1  361 158 AMBIENT AIR POLLUTION AND THROMBOSIS. AIR POLLUTION IS A GROWING PUBLIC HEALTH CONCERN OF GLOBAL SIGNIFICANCE. ACUTE AND CHRONIC EXPOSURE IS KNOWN TO IMPAIR CARDIOVASCULAR FUNCTION, EXACERBATE DISEASE AND INCREASE CARDIOVASCULAR MORTALITY. SEVERAL PLAUSIBLE BIOLOGICAL MECHANISMS HAVE BEEN PROPOSED FOR THESE ASSOCIATIONS, HOWEVER, AT PRESENT, THE PATHWAYS ARE INCOMPLETE. A SEMINAL REVIEW BY THE AMERICAN HEART ASSOCIATION (2010) CONCLUDED THAT THE THROMBOTIC EFFECTS OF PARTICULATE AIR POLLUTION LIKELY CONTRIBUTED TO THEIR EFFECTS ON CARDIOVASCULAR MORTALITY AND MORBIDITY. THE AIM OF THE CURRENT REVIEW IS TO APPRAISE THE NEWLY ACCUMULATED SCIENTIFIC EVIDENCE (2009-2016) ON CONTRIBUTION OF HAEMOSTASIS AND THROMBOSIS TOWARDS CARDIOVASCULAR DISEASE INDUCED BY EXPOSURE TO BOTH PARTICULATE AND GASEOUS POLLUTANTS.SEVENTY FOUR PUBLICATIONS WERE REVIEWED IN-DEPTH. THE WEIGHT OF EVIDENCE SUGGESTS THAT ACUTE EXPOSURE TO FINE PARTICULATE MATTER (PM(2.5)) INDUCES A SHIFT IN THE HAEMOSTATIC BALANCE TOWARDS A PRO-THROMBOTIC/PRO-COAGULATIVE STATE. INSUFFICIENT DATA WAS AVAILABLE TO ASCERTAIN IF A SIMILAR RELATIONSHIP EXISTS FOR GASEOUS POLLUTANTS, AND VERY FEW STUDIES HAVE ADDRESSED LONG-TERM EXPOSURE TO AMBIENT AIR POLLUTION. PLATELET ACTIVATION, OXIDATIVE STRESS, INTERPLAY BETWEEN INTERLEUKIN-6 AND TISSUE FACTOR, ALL APPEAR TO BE POTENTIALLY IMPORTANT MECHANISMS IN POLLUTION-MEDIATED THROMBOSIS, TOGETHER WITH AN EMERGING ROLE FOR CIRCULATING MICROVESICLES AND EPIGENETIC CHANGES.OVERALL, THE RECENT LITERATURE SUPPORTS, AND ARGUABLY STRENGTHENS, THE CONTENTION THAT AIR POLLUTION CONTRIBUTES TO CARDIOVASCULAR MORBIDITY BY PROMOTING HAEMOSTASIS. THE VOLUME AND DIVERSITY OF THE EVIDENCE HIGHLIGHTS THE COMPLEXITY OF THE PATHOPHYSIOLOGIC MECHANISMS BY WHICH AIR POLLUTION PROMOTES THROMBOSIS; MULTIPLE PATHWAYS ARE PLAUSIBLE AND IT IS MOST LIKELY THEY ACT IN CONCERT. FUTURE RESEARCH SHOULD ADDRESS THE ROLE GASEOUS POLLUTANTS PLAY IN THE CARDIOVASCULAR EFFECTS OF AIR POLLUTION MIXTURE AND DIRECT COMPARISON OF POTENTIALLY SUSCEPTIBLE GROUPS TO HEALTHY INDIVIDUALS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
2 6781  57 [BREATHING: AMBIENT AIR POLLUTION AND HEALTH - PART III]. THE THIRD PART OF THE DGP STATEMENT INTRODUCES THE CURRENT BODY OF KNOWLEDGE ON LESS STUDIED HEALTH OUTCOMES ASSOCIATED WITH EXPOSURE TO AMBIENT AIR POLLUTION: THE NEGATIVE IMPACT ON METABOLISM LEADING TO IMPAIRED GLUCOSE TOLERANCE AND DIABETES AS WELL AS CONTRIBUTION TO THE DEVELOPMENT OF NEURODEGENERATIVE DISORDERS AND DELAYED COGNITIVE FUNCTION IN CHILDREN. FURTHERMORE, PRENATAL EXPOSURE AND ADVERSE EFFECTS ON MOTHER AND CHILD ARE ADDRESSED. FINALLY, THE CURRENTLY DISCUSSED BIOLOGICAL MECHANISMS UNDERLYING VARIOUS HEALTH EFFECTS ASSOCIATED WITH EXPOSURE TO AIR POLLUTION ARE DESCRIBED.DIFFERING, BUT OFTEN COMPLEMENTARY BIOLOGICAL MECHANISMS CREATE THE BASIS FOR THE DIVERSE HEALTH OUTCOMES CAUSED BY AIR POLLUTION. OXIDATIVE STRESS AND A SUBCLINICAL INFLAMMATORY RESPONSE IN THE LUNGS AND ON A SYSTEMIC LEVEL ("LOW-GRADE SYSTEMIC INFLAMMATION") ARE CONSIDERED TO BE KEY MECHANISMS. THEY PROMOTE SECONDARY ALTERATIONS IN THE BODY, SUCH AS VASCULAR OR METABOLIC PROCESSES, AND MAY ALSO RESULT IN THE CURRENTLY STUDIED EPIGENETIC PHENOMENA OR NEUROINFLAMMATION. IN THIS CONTEXT, THE HEALTH SIGNIFICANCE OF SOLUBLE PARTICULATE MATTER AND THE ROLE OF ULTRAFINE PARTICLES TRANSLOCATED ACROSS BIOLOGICAL MEMBRANES INTO BLOOD VESSEL AND TRANSPORTED VIA THE CIRCULATION TO SECONDARY TARGET ORGANS, SUCH AS LIVER, BRAIN OR THE FETUS, ARE INTENSIVELY DISCUSSED.DIABETES IS ONE OF THE LEADING CHRONIC DISEASES WORLDWIDE, WITH A PREVALENCE OF ALMOST 14 % IN GERMANY. ALTHOUGH LIFESTYLE FACTORS ARE THE MAIN CAUSES, CURRENT EVIDENCE SUGGESTS THAT LONG-TERM EXPOSURE TO AIR POLLUTION MAY ADDITIONALLY INCREASE THE RISK FOR TYPE 2 DIABETES. SUPPORTING EVIDENCE FOR A CAUSAL ROLE OF AIR POLLUTION IS PROVIDED BY STUDIES ADDRESSING THE REGULATION OF THE BLOOD GLUCOSE LEVELS IN METABOLICALLY HEALTHY PARTICIPANTS, INSULIN SENSITIVITY, OR PREGNANCY-RELATED DIABETES. EXPERIMENTAL STUDIES PROVIDE FURTHER SUPPORT FOR PLAUSIBLE BIOLOGICAL MECHANISMS. HOWEVER, PROSPECTIVE STUDIES ARE NEEDED TO GAIN MORE EVIDENCE, TAKING MULTIPLE LIFESTYLE AND ENVIRONMENTAL FACTORS, SUCH AS GREEN SPACE AND NOISE, AND AN IMPROVED INDIVIDUAL EXPOSURE ASSESSMENT INTO ACCOUNT.THE AGING POPULATION HAS AN INCREASED RISK OF NEURODEGENERATIVE DISEASES. FIRST STUDIES POINT TOWARDS A CONTRIBUTION OF CHRONIC EXPOSURE TO AIR POLLUTION, SPECIFICALLY BY PARTICULATE MATTER. SEVERAL STUDIES REPORT ITS ASSOCIATION WITH DECREASED NEUROCOGNITIVE CAPACITY OR AN INCREASED PREVALENCE OF DEMENTIA OR ALZHEIMER'S DISEASE IN ADULTS. HOWEVER, THE STUDIES ARE INHOMOGENEOUS REGARDING DESIGN, EXPOSURE AND OUTCOME, LEADING TO INCONSISTENT RESULTS. WITH RESPECT TO THE INFLUENCE ON NEUROCOGNITIVE DEVELOPMENT OF CHILDREN, FIRST STUDIES SUGGEST AN ASSOCIATION BETWEEN THE LEVEL OF AIR POLLUTION, E. G. AT SCHOOL, AND DELAYED COGNITIVE DEVELOPMENT.EVEN THOUGH THE EVIDENCE FOR THE DIFFERENT BIOLOGICAL ENDPOINTS DURING PREGNANCY IS STILL HETEROGENEOUS, THE STUDIES GENERALLY POINT TOWARDS AN ADVERSE IMPACT OF AIR POLLUTION ON THE MATERNAL AND FETAL ORGANISMS. THE STRONGEST EVIDENCE EXISTS FOR LOW BIRTH WEIGHT, WITH SMALL EFFECT SIZES OF ONLY SOME GRAMS, AND FOR A HIGHER INCIDENCE OF REDUCED BIRTH WEIGHT (< 2500 G). AN INCREASED RISK FOR GESTATIONAL HYPERTENSION AND PREECLAMPSIA UNDERSCORES THE POSSIBLE IMPACT OF EXPOSURE TO AIR POLLUTION ON THE MATERNAL ORGANISM. HOWEVER, THE CURRENT BODY OF EVIDENCE DOES NOT YET ALLOW A FINAL CONCLUSION ON THE INFLUENCE OF INTRAUTERINE EXPOSURE TO AIR POLLUTION REGARDING EARLY CHILDHOOD LUNG FUNCTION AND DEVELOPMENT OF ALLERGIES, PARTICULARLY IN LIGHT OF THE FACT THAT IT IS HARD TO DISTINGUISH IN EPIDEMIOLOGICAL STUDIES BETWEEN THE EFFECTS OF PRE- AND POSTNATAL EXPOSURE.	2019	

3  360  29 AMBIENT AIR POLLUTION AND BIOMARKERS OF HEALTH EFFECT. RECENTLY, THE AIR POLLUTION SITUATION OF OUR COUNTRY IS VERY SERIOUS ALONG WITH THE DEVELOPMENT OF URBANIZATION AND INDUSTRIALIZATION. STUDIES INDICATE THAT THE EXPOSURE OF AIR POLLUTION CAN CAUSE A RISE OF INCIDENCE AND MORTALITY OF MANY DISEASES, SUCH AS CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), ASTHMA, MYOCARDIAL INFARCTION, AND SO ON. HOWEVER, THERE IS NOW GROWING EVIDENCE SHOWING THAT SIGNIFICANT AIR POLLUTION EXPOSURES ARE ASSOCIATED WITH EARLY BIOMARKERS IN VARIOUS SYSTEMS OF THE BODY. IN ORDER TO BETTER PREVENT AND CONTROL THE DAMAGE EFFECT OF AIR POLLUTION, THIS ARTICLE SUMMARIZES COMPREHENSIVELY EPIDEMIOLOGICAL STUDIES ABOUT THE BAD EFFECTS ON THE BIOMARKERS OF RESPIRATORY SYSTEM, CARDIOVASCULAR SYSTEM, AND GENETIC AND EPIGENETIC SYSTEM EXPOSURE TO AMBIENT AIR POLLUTION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
4 1324  43 DEOXYRIBONUCLEIC ACID (DNA) METHYLATION IN CHILDREN EXPOSED TO AIR POLLUTION: A POSSIBLE MECHANISM UNDERLYING RESPIRATORY HEALTH EFFECTS DEVELOPMENT. AIR POLLUTION IS A SUBSTANTIAL ENVIRONMENTAL THREAT TO CHILDREN AND ACTS AS ACUTE AND CHRONIC DISEASE RISK FACTORS ALIKE. SEVERAL STUDIES HAVE PREVIOUSLY EVALUATED EPIGENETIC MODIFICATIONS CONCERNING ITS EXPOSURE ACROSS VARIOUS LIFE STAGES. HOWEVER, FINDINGS ON EPIGENETIC MODIFICATIONS AS THE CONSEQUENCES OF AIR POLLUTION DURING CHILDHOOD ARE RATHER MINIMAL. THIS REVIEW EVALUATED HIGHLY RELEVANT STUDIES IN THE FIELD TO ANALYZE THE EXISTING LITERATURE REGARDING EXPOSURE TO AIR POLLUTION, WITH A FOCUS ON EPIGENETIC ALTERATIONS DURING CHILDHOOD AND THEIR CONNECTIONS WITH RESPIRATORY HEALTH EFFECTS. THE SEARCH WAS CONDUCTED USING READILY AVAILABLE ELECTRONIC DATABASES (PUBMED AND SCIENCEDIRECT) TO SCREEN FOR CHILDREN'S STUDIES ON EPIGENETIC MECHANISMS FOLLOWING EITHER PRE- OR POST-NATAL EXPOSURE TO AIR POLLUTANTS. STUDIES RELEVANT ENOUGH AND MATCHED THE PREDETERMINED CRITERIA WERE CHOSEN TO BE REVIEWED. NON-ENGLISH ARTICLES AND STUDIES THAT DID NOT REPORT BOTH AIR MONITORING AND EPIGENETIC OUTCOMES IN THE SAME ARTICLE WERE EXCLUDED. THE REVIEW FOUND THAT EPIGENETIC CHANGES HAVE BEEN LINKED WITH EXPOSURE TO AIR POLLUTANTS DURING EARLY LIFE WITH EVIDENCE AND REPORTS OF HOW THEY MAY DEREGULATE THE EPIGENOME BALANCE, THUS INDUCING DISEASE PROGRESSION IN THE FUTURE. EPIGENETIC STUDIES EVOLVE AS A PROMISING NEW APPROACH IN DECIPHERING THE UNDERLYING IMPACTS OF AIR POLLUTION ON DEOXYRIBONUCLEIC ACID (DNA) DUE TO LINKS ESTABLISHED BETWEEN SOME OF THESE EPIGENETIC MECHANISMS AND ILLNESSES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5 3106  37 GENOMICS AND THE RESPIRATORY EFFECTS OF AIR POLLUTION EXPOSURE. ADVERSE HEALTH EFFECTS FROM AIR POLLUTANTS REMAIN IMPORTANT, DESPITE IMPROVEMENT IN AIR QUALITY IN THE PAST FEW DECADES. THE EXACT MECHANISMS OF LUNG INJURY FROM EXPOSURE TO AIR POLLUTANTS ARE NOT YET FULLY UNDERSTOOD. STUDYING THE GENOME (E.G. SINGLE-NUCLEOTIDE POLYMORPHISMS (SNP) ), EPIGENOME (E.G. METHYLATION OF GENES), TRANSCRIPTOME (MRNA EXPRESSION) AND MICRORNAOME (MICRORNA EXPRESSION) HAS THE POTENTIAL TO IMPROVE OUR UNDERSTANDING OF THE ADVERSE EFFECTS OF AIR POLLUTANTS. GENOME-WIDE ASSOCIATION STUDIES OF SNP HAVE DETECTED SNP ASSOCIATED WITH RESPIRATORY PHENOTYPES; HOWEVER, TO DATE, ONLY CANDIDATE GENE STUDIES OF AIR POLLUTION EXPOSURE HAVE BEEN PERFORMED. CHANGES IN EPIGENETIC PROCESSES, SUCH DNA METHYLATION THAT LEADS TO GENE SILENCING WITHOUT ALTERING THE DNA SEQUENCE, OCCUR WITH AIR POLLUTANT EXPOSURE, ESPECIALLY GLOBAL AND GENE-SPECIFIC METHYLATION CHANGES. RESPIRATORY CELL LINE AND ANIMAL MODELS DEMONSTRATE DISTINCT GENE EXPRESSION SIGNATURES IN THE TRANSCRIPTOME, ARISING FROM EXPOSURE TO PARTICULATE MATTER OR OZONE. PARTICULATE MATTER AND OTHER ENVIRONMENTAL TOXINS ALTER EXPRESSION OF MICRORNA, WHICH ARE SHORT NON-CODING RNA THAT REGULATE GENE EXPRESSION. WHILE IT IS CLEARLY IMPORTANT TO CONTAIN RISING LEVELS OF AIR POLLUTION, STRATEGIES ALSO NEED TO BE DEVELOPED TO MINIMIZE THE DAMAGING EFFECTS OF AIR POLLUTANT EXPOSURE ON THE LUNG, ESPECIALLY FOR PATIENTS WITH CHRONIC LUNG DISEASE AND FOR PEOPLE AT RISK OF FUTURE LUNG DISEASE. CAREFUL STUDY OF GENOMIC RESPONSES WILL IMPROVE OUR UNDERSTANDING OF MECHANISMS OF LUNG INJURY FROM AIR POLLUTION AND ENABLE FUTURE CLINICAL TESTING OF INTERVENTIONS AGAINST THE TOXIC EFFECTS OF AIR POLLUTANTS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
6 2849  34 FROM AIR POLLUTION TO CARDIOVASCULAR DISEASES: THE EMERGING ROLE OF EPIGENETICS. THE ASSOCIATION BETWEEN AIR POLLUTION AND A WIDE-RANGING SPECTRUM OF ACUTE AND CHRONIC DISORDERS-INCLUDING CARDIOVASCULAR DISEASES-IS WIDELY ACKNOWLEDGED. EXPOSURE TO AIRBORNE POLLUTANTS TRIGGERS HARMFUL MECHANISMS SUCH AS OXIDATIVE STRESS AND SYSTEMIC INFLAMMATION, WHICH LEAD TO INCREASED INCIDENCE OF MYOCARDIAL INFARCTION, ARTERIAL HYPERTENSION, STROKE, AND HEART FAILURE. SUSTAINED EFFORTS HAVE BEEN MADE IN RECENT YEARS TO DISCOVER HOW ENVIRONMENTAL EXPOSURES AFFECT HUMAN HEALTH THROUGH EPIGENETIC PHENOMENA, SUCH AS DNA METHYLATION, HISTONE MODIFICATIONS AND NON-CODING RNA-MEDIATED GENE REGULATION. THIS REVIEW SUMMARIZES THE CURRENT EVIDENCES ON THE RELATIONSHIP BETWEEN AIR POLLUTION EXPOSURE, EPIGENETIC ALTERATIONS AND CARDIOVASCULAR IMPACT, IN VIEW OF PRESENT IMPLICATIONS AND FUTURE PERSPECTIVES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
7  754  43 CARDIOVASCULAR ADAPTATIONS TO PARTICLE INHALATION EXPOSURE: MOLECULAR MECHANISMS OF THE TOXICOLOGY. AMBIENT AIR, OCCUPATIONAL SETTINGS, AND THE USE AND DISTRIBUTION OF CONSUMER PRODUCTS ALL SERVE AS CONDUITS FOR TOXICANT EXPOSURE THROUGH INHALATION. WHILE THE PULMONARY SYSTEM REMAINS A PRIMARY TARGET FOLLOWING INHALATION EXPOSURE, CARDIOVASCULAR IMPLICATIONS ARE EXCEPTIONALLY CULPABLE FOR INCREASED MORBIDITY AND MORTALITY. THE EPIDEMIOLOGICAL EVIDENCE FOR CARDIOVASCULAR DYSFUNCTION RESULTING FROM ACUTE OR CHRONIC INHALATION EXPOSURE TO PARTICULATE MATTER HAS BEEN WELL DOCUMENTED, BUT THE MECHANISMS DRIVING THE RESULTING DISTURBANCES REMAIN ELUSIVE. IN THE CURRENT REVIEW, WE AIM TO SUMMARIZE THE CELLULAR AND MOLECULAR MECHANISMS THAT ARE DIRECTLY LINKED TO CARDIOVASCULAR HEALTH FOLLOWING EXPOSURE TO A VARIETY OF INHALED TOXICANTS. THE PURPOSE OF THIS REVIEW IS TO PROVIDE A COMPREHENSIVE OVERVIEW OF THE BIOCHEMICAL CHANGES IN THE CARDIOVASCULAR SYSTEM FOLLOWING PARTICLE INHALATION EXPOSURE AND TO HIGHLIGHT POTENTIAL BIOMARKERS THAT EXIST ACROSS MULTIPLE EXPOSURE PARADIGMS. WE ATTEMPT TO INTEGRATE THESE MOLECULAR SIGNATURES IN AN EFFORT TO PROVIDE DIRECTION FOR FUTURE INVESTIGATIONS. THIS REVIEW ALSO CHARACTERIZES HOW MOLECULAR RESPONSES ARE MODIFIED IN AT-RISK POPULATIONS, SPECIFICALLY THE IMPACT OF ENVIRONMENTAL EXPOSURE DURING CRITICAL WINDOWS OF DEVELOPMENT. MATERNAL EXPOSURE TO PARTICULATE MATTER DURING GESTATION CAN LEAD TO FETAL EPIGENETIC REPROGRAMMING, RESULTING IN LONG-TERM DEFICITS TO THE CARDIOVASCULAR SYSTEM. IN BOTH DIRECT AND INDIRECT (GESTATIONAL) EXPOSURES, CONNECTING THE BIOCHEMICAL MECHANISMS WITH FUNCTIONAL DEFICITS OUTLINES PATHWAYS THAT CAN BE TARGETED FOR FUTURE THERAPEUTIC INTERVENTION. ULTIMATELY, FUTURE INVESTIGATIONS INTEGRATING "OMICS"-BASED APPROACHES WILL BETTER ELUCIDATE THE MECHANISMS THAT ARE ALTERED BY XENOBIOTIC INHALATION EXPOSURE, IDENTIFY BIOMARKERS, AND GUIDE IN CLINICAL DECISION MAKING.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
8 1932  41 ENVIRONMENTAL EXPOSURES: AN UNDERRECOGNIZED CONTRIBUTION TO NONCOMMUNICABLE DISEASES. PREVIOUS ATTEMPTS TO DETERMINE THE DEGREE TO WHICH EXPOSURE TO ENVIRONMENTAL FACTORS CONTRIBUTE TO NONCOMMUNICABLE DISEASES (NCDS) HAVE BEEN VERY CONSERVATIVE AND HAVE SIGNIFICANTLY UNDERESTIMATED THE ACTUAL CONTRIBUTION OF THE ENVIRONMENT FOR AT LEAST TWO REASONS. FIRSTLY, MOST PREVIOUS REPORTS HAVE EXCLUDED THE CONTRIBUTION OF LIFESTYLE BEHAVIORAL RISK FACTORS, BUT THESE USUALLY INVOLVE SIGNIFICANT EXPOSURE TO ENVIRONMENTAL CHEMICALS THAT INCREASE RISK OF DISEASE. SECONDLY, EARLY LIFE EXPOSURE TO CHEMICAL CONTAMINANTS IS NOW CLEARLY ASSOCIATED WITH AN ELEVATED RISK OF SEVERAL DISEASES LATER IN LIFE, BUT THESE CONNECTIONS ARE OFTEN DIFFICULT TO DISCERN. THIS IS ESPECIALLY TRUE FOR ASTHMA AND NEURODEVELOPMENTAL CONDITIONS, BUT THERE IS ALSO A MAJOR CONTRIBUTION TO THE DEVELOPMENT OF OBESITY AND CHRONIC DISEASES. MOST CANCERS ARE CAUSED BY ENVIRONMENTAL EXPOSURES IN GENETICALLY SUSCEPTIBLE INDIVIDUALS. IN ADDITION, NEW INFORMATION SHOWS SIGNIFICANT ASSOCIATIONS BETWEEN CARDIOVASCULAR DISEASES AND DIABETES AND EXPOSURE TO ENVIRONMENTAL CHEMICALS PRESENT IN AIR, FOOD, AND WATER. THESE RELATIONSHIPS LIKELY REFLECT THE COMBINATION OF EPIGENETIC EFFECTS AND GENE INDUCTION. ENVIRONMENTAL FACTORS CONTRIBUTE SIGNIFICANTLY MORE TO NCDS THAN PREVIOUS REPORTS HAVE SUGGESTED. PREVENTION NEEDS TO SHIFT FOCUS FROM INDIVIDUAL RESPONSIBILITY TO SOCIETAL RESPONSIBILITY AND AN UNDERSTANDING THAT EFFECTIVE PREVENTION OF NCDS ULTIMATELY RELIES ON IMPROVED ENVIRONMENTAL MANAGEMENT TO REDUCE EXPOSURE TO MODIFIABLE RISKS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
9  299  41 AIR POLLUTION AND DNA METHYLATION: EFFECTS OF EXPOSURE IN HUMANS. AIR POLLUTION EXPOSURE IS ESTIMATED TO CONTRIBUTE TO APPROXIMATELY SEVEN MILLION EARLY DEATHS EVERY YEAR WORLDWIDE AND MORE THAN 3% OF DISABILITY-ADJUSTED LIFE YEARS LOST. AIR POLLUTION HAS NUMEROUS HARMFUL EFFECTS ON HEALTH AND CONTRIBUTES TO THE DEVELOPMENT AND MORBIDITY OF CARDIOVASCULAR DISEASE, METABOLIC DISORDERS, AND A NUMBER OF LUNG PATHOLOGIES, INCLUDING ASTHMA AND CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). EMERGING DATA INDICATE THAT AIR POLLUTION EXPOSURE MODULATES THE EPIGENETIC MARK, DNA METHYLATION (DNAM), AND THAT THESE CHANGES MIGHT IN TURN INFLUENCE INFLAMMATION, DISEASE DEVELOPMENT, AND EXACERBATION RISK. SEVERAL TRAFFIC-RELATED AIR POLLUTION (TRAP) COMPONENTS, INCLUDING PARTICULATE MATTER (PM), BLACK CARBON (BC), OZONE (O(3)), NITROGEN OXIDES (NO(X)), AND POLYAROMATIC HYDROCARBONS (PAHS), HAVE BEEN ASSOCIATED WITH CHANGES IN DNAM; TYPICALLY LOWERING DNAM AFTER EXPOSURE. EFFECTS OF AIR POLLUTION ON DNAM HAVE BEEN OBSERVED ACROSS THE HUMAN LIFESPAN, BUT IT IS NOT YET CLEAR WHETHER EARLY LIFE DEVELOPMENTAL SENSITIVITY OR THE ACCUMULATION OF EXPOSURES HAVE THE MOST SIGNIFICANT EFFECTS ON HEALTH. AIR POLLUTION EXPOSURE-ASSOCIATED DNAM PATTERNS ARE OFTEN CORRELATED WITH LONG-TERM NEGATIVE RESPIRATORY HEALTH OUTCOMES, INCLUDING THE DEVELOPMENT OF LUNG DISEASES, A FOCUS IN THIS REVIEW. RECENTLY, INTERVENTIONS SUCH AS EXERCISE AND B VITAMINS HAVE BEEN PROPOSED TO REDUCE THE IMPACT OF AIR POLLUTION ON DNAM AND HEALTH. ULTIMATELY, IMPROVED KNOWLEDGE OF HOW EXPOSURE-INDUCED CHANGE IN DNAM IMPACTS HEALTH, BOTH ACUTELY AND CHRONICALLY, MAY ENABLE PREVENTATIVE AND REMEDIAL STRATEGIES TO REDUCE MORBIDITY IN POLLUTED ENVIRONMENTS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10  625  35 BIOLOGICAL AGE AND ENVIRONMENTAL RISK FACTORS FOR DEMENTIA AND STROKE: MOLECULAR MECHANISMS. SINCE THE DEVELOPMENT OF ANTIBIOTICS AND VACCINATION, AS WELL AS MAJOR IMPROVEMENTS IN PUBLIC HYGIENE, THE MAIN RISK FACTORS FOR MORBIDITY AND MORTALITY ARE AGE AND CHRONIC EXPOSURE TO ENVIRONMENTAL FACTORS, BOTH OF WHICH CAN INTERACT WITH GENETIC PREDISPOSITIONS. AS THE AVERAGE AGE OF THE POPULATION INCREASES, THE PREVALENCE AND COSTS OF CHRONIC DISEASES, ESPECIALLY NEUROLOGICAL CONDITIONS, ARE RAPIDLY INCREASING. THE DELETERIOUS EFFECTS OF AGE AND ENVIRONMENTAL RISK FACTORS, DEVELOP CHRONICALLY OVER RELATIVELY LONG PERIODS OF TIME, IN CONTRAST TO THE RELATIVELY RAPID DELETERIOUS EFFECTS OF INFECTIOUS DISEASES OR ACCIDENTS. OF PARTICULAR INTEREST IS THE HYPOTHESIS THAT THE DELETERIOUS EFFECTS OF ENVIRONMENTAL FACTORS MAY BE MEDIATED BY ACCELERATION OF BIOLOGICAL AGE. THIS HYPOTHESIS IS SUPPORTED BY EVIDENCE THAT DIETARY RESTRICTION, WHICH UNIVERSALLY DELAYS AGE-RELATED DISEASES, ALSO AMELIORATES DELETERIOUS EFFECTS OF ENVIRONMENTAL FACTORS. CONVERSELY, BOTH AGE AND ENVIRONMENTAL RISK FACTORS ARE ASSOCIATED WITH THE ACCUMULATION OF SOMATIC MUTATIONS IN MITOTIC CELLS AND EPIGENETIC MODIFICATIONS THAT ARE A MEASURE OF "BIOLOGICAL AGE", A BETTER PREDICTOR OF AGE-RELATED MORBIDITY AND MORTALITY THAN CHRONOLOGICAL AGE. HERE WE REVIEW EVIDENCE THAT ENVIRONMENTAL RISK FACTORS SUCH AS SMOKING AND AIR POLLUTION MAY ALSO DRIVE NEUROLOGICAL CONDITIONS, INCLUDING ALZHEIMER'S DISEASE, BY THE ACCELERATION OF BIOLOGICAL AGE, MEDIATED BY CUMULATIVE AND PERSISTENT EPIGENETIC EFFECTS AS WELL AS SOMATIC MUTATIONS. ELUCIDATION OF SUCH MECHANISMS COULD PLAUSIBLY ALLOW THE DEVELOPMENT OF INTERVENTIONS WHICH DELAY DELETERIOUS EFFECTS OF BOTH AGING AND ENVIRONMENTAL RISK FACTORS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
11 1157  40 CONTAMINANT METALS AS CARDIOVASCULAR RISK FACTORS: A SCIENTIFIC STATEMENT FROM THE AMERICAN HEART ASSOCIATION. EXPOSURE TO ENVIRONMENTAL POLLUTANTS IS LINKED TO INCREASED RISK OF CARDIOVASCULAR DISEASE. BEYOND THE EXTENSIVE EVIDENCE FOR PARTICULATE AIR POLLUTION, ACCUMULATING EVIDENCE SUPPORTS THAT EXPOSURE TO NONESSENTIAL METALS SUCH AS LEAD, CADMIUM, AND ARSENIC IS A SIGNIFICANT CONTRIBUTOR TO CARDIOVASCULAR DISEASE WORLDWIDE. HUMANS ARE EXPOSED TO METALS THROUGH AIR, WATER, SOIL, AND FOOD AND EXTENSIVE INDUSTRIAL AND PUBLIC USE. CONTAMINANT METALS INTERFERE WITH CRITICAL INTRACELLULAR REACTIONS AND FUNCTIONS LEADING TO OXIDATIVE STRESS AND CHRONIC INFLAMMATION THAT RESULT IN ENDOTHELIAL DYSFUNCTION, HYPERTENSION, EPIGENETIC DYSREGULATION, DYSLIPIDEMIA, AND CHANGES IN MYOCARDIAL EXCITATION AND CONTRACTILE FUNCTION. LEAD, CADMIUM, AND ARSENIC HAVE BEEN LINKED TO SUBCLINICAL ATHEROSCLEROSIS, CORONARY ARTERY STENOSIS, AND CALCIFICATION AS WELL AS TO INCREASED RISK OF ISCHEMIC HEART DISEASE AND STROKE, LEFT VENTRICULAR HYPERTROPHY AND HEART FAILURE, AND PERIPHERAL ARTERY DISEASE. EPIDEMIOLOGICAL STUDIES SHOW THAT EXPOSURE TO LEAD, CADMIUM, OR ARSENIC IS ASSOCIATED WITH CARDIOVASCULAR DEATH MOSTLY ATTRIBUTABLE TO ISCHEMIC HEART DISEASE. PUBLIC HEALTH MEASURES REDUCING METAL EXPOSURE ARE ASSOCIATED WITH REDUCTIONS IN CARDIOVASCULAR DISEASE DEATH. POPULATIONS OF COLOR AND LOW SOCIOECONOMIC MEANS ARE MORE COMMONLY EXPOSED TO METALS AND THEREFORE AT GREATER RISK OF METAL-INDUCED CARDIOVASCULAR DISEASE. TOGETHER WITH STRENGTHENING PUBLIC HEALTH MEASURES TO PREVENT METAL EXPOSURES, DEVELOPMENT OF MORE SENSITIVE AND SELECTIVE MEASUREMENT MODALITIES, CLINICAL MONITORING OF METAL EXPOSURES, AND THE DEVELOPMENT OF METAL CHELATION THERAPIES COULD FURTHER DIMINISH THE BURDEN OF CARDIOVASCULAR DISEASE ATTRIBUTABLE TO METAL EXPOSURE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12  303  38 AIR POLLUTION STRESS AND THE AGING PHENOTYPE: THE TELOMERE CONNECTION. AGING IS A COMPLEX PHYSIOLOGICAL PHENOMENON. THE QUESTION WHY SOME SUBJECTS GROW OLD WHILE REMAINING FREE FROM DISEASE WHEREAS OTHERS PREMATURELY DIE REMAINS LARGELY UNANSWERED. WE FOCUS HERE ON THE ROLE OF AIR POLLUTION IN BIOLOGICAL AGING. HALLMARKS OF AGING CAN BE GROUPED INTO THREE MAIN CATEGORIES: GENOMIC INSTABILITY, TELOMERE ATTRITION, AND EPIGENETIC ALTERATIONS LEADING TO ALTERED MITOCHONDRIAL FUNCTION AND CELLULAR SENESCENCE. AT BIRTH, THE INITIAL TELOMERE LENGTH OF A PERSON IS LARGELY DETERMINED BY ENVIRONMENTAL FACTORS. TELOMERE LENGTH SHORTENS WITH EACH CELL DIVISION AND EXPOSURE TO AIR POLLUTION AS WELL AS LOW RESIDENTIAL GREENS SPACE EXPOSURE IS ASSOCIATED WITH SHORTER TELOMERE LENGTH. RECENT STUDIES SHOW THAT THE ESTIMATED EFFECTS OF PARTICULATE AIR POLLUTION EXPOSURE ON THE TELOMERE MITOCHONDRIAL AXIS OF AGING MAY PLAY AN IMPORTANT ROLE IN CHRONIC HEALTH EFFECTS OF AIR POLLUTION. THE EXPOSOME ENCOMPASSES ALL EXPOSURES OVER AN ENTIRE LIFE. AS TELOMERES CAN BE CONSIDERED AS THE CELLULAR MEMORIES OF EXPOSURE TO OXIDATIVE STRESS AND INFLAMMATION, TELOMERE MAINTENANCE MAY BE A PROXY FOR ASSESSING THE "EXPOSOME". IF TELOMERES ARE CAUSALLY RELATED TO THE AGING PHENOTYPE AND ENVIRONMENTAL AIR POLLUTION IS AN IMPORTANT DETERMINANT OF TELOMERE LENGTH, THIS MIGHT PROVIDE NEW AVENUES FOR FUTURE PREVENTIVE STRATEGIES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13 5254  45 PROGRAMMING OF RESPIRATORY HEALTH IN CHILDHOOD: INFLUENCE OF OUTDOOR AIR POLLUTION. PURPOSE OF REVIEW: THIS OVERVIEW HIGHLIGHTS RECENT EXPERIMENTAL AND EPIDEMIOLOGICAL EVIDENCE FOR THE PROGRAMMING EFFECTS OF OUTDOOR AIR POLLUTION EXPOSURES DURING EARLY DEVELOPMENT ON LUNG FUNCTION AND CHRONIC RESPIRATORY DISORDERS, SUCH AS ASTHMA AND RELATED ALLERGIC DISORDERS. RECENT FINDINGS: AIR POLLUTANTS MAY IMPACT ANATOMY AND/OR PHYSIOLOGICAL FUNCTIONING OF THE LUNG AND INTERRELATED SYSTEMS. PROGRAMMING EFFECTS MAY RESULT FROM POLLUTANT-INDUCED SHIFTS IN A NUMBER OF MOLECULAR, CELLULAR, AND PHYSIOLOGICAL STATES AND THEIR INTERACTING SYSTEMS. SPECIFIC KEY REGULATORY SYSTEMS SUSCEPTIBLE TO PROGRAMMING MAY INFLUENCE LUNG DEVELOPMENT AND VULNERABILITY TO RESPIRATORY DISEASES, INCLUDING BOTH CENTRAL AND PERIPHERAL COMPONENTS OF NEUROENDOCRINE PATHWAYS AND AUTONOMIC NERVOUS SYSTEM (ANS) FUNCTIONING WHICH, IN TURN, INFLUENCE THE IMMUNE SYSTEM. STARTING IN UTERO, ENVIRONMENTAL FACTORS, INCLUDING AIR POLLUTANTS, MAY PERMANENTLY ORGANIZE THESE SYSTEMS TOWARD TRAJECTORIES OF ENHANCED PEDIATRIC (E.G., ASTHMA, ALLERGY) AS WELL AS ADULT DISEASE RISK (E.G., CHRONIC OBSTRUCTIVE PULMONARY DISEASE). EVIDENCE SUPPORTS A CENTRAL ROLE OF OXIDATIVE STRESS IN THE TOXIC EFFECTS OF AIR POLLUTION. ADDITIONAL RESEARCH SUGGESTS XENOBIOTIC METABOLISM AND SUBCELLULAR COMPONENTS, SUCH AS MITOCHONDRIA ARE TARGETS OF AMBIENT AIR POLLUTION AND PLAY A ROLE IN ASTHMA AND ALLERGY PROGRAMMING. MECHANISMS OPERATING AT THE LEVEL OF THE PLACENTA ARE BEING ELUCIDATED. EPIGENETIC MECHANISMS MAY BE AT THE ROOTS OF ADAPTIVE DEVELOPMENTAL PROGRAMMING. SUMMARY: OPTIMAL COORDINATED FUNCTIONING OF MANY COMPLEX PROCESSES AND THEIR NETWORKS OF INTERACTION ARE NECESSARY FOR NORMAL LUNG DEVELOPMENT AND THE MAINTENANCE OF RESPIRATORY HEALTH. OUTDOOR AIR POLLUTION MAY PLAY AN IMPORTANT ROLE IN EARLY PROGRAMMING OF RESPIRATORY HEALTH AND IS POTENTIALLY AMENABLE TO INTERVENTION.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
14 5434  29 RELATIONSHIP BETWEEN ENVIRONMENTAL EXPOSURES IN CHILDREN AND ADULT LUNG DISEASE: THE CASE FOR OUTDOOR EXPOSURES. THERE IS A GROWING UNDERSTANDING THAT CHRONIC RESPIRATORY DISEASES IN ADULTS HAVE THEIR ORIGINS IN EARLY LIFE. ADVERSE ENVIRONMENTAL EXPOSURES OCCURRING IN VULNERABLE PERIODS DURING LUNG GROWTH AND DEVELOPMENT IN THE FETAL PERIOD AND IN EARLY CHILDHOOD THAT ALTER LUNG STRUCTURE AND LIMIT THE GROWTH IN LUNG FUNCTION MAY HAVE LIFELONG CONSEQUENCES. EVIDENCE IS INCREASING THAT EXPOSURE TO THE AMBIENT ENVIRONMENT, INCLUDING AIR POLLUTANTS, PERSISTENT TOXIC SUBSTANCES, WATER POLLUTANTS AND RESPIRATORY VIRAL INFECTIONS, CAN INHIBIT LUNG FUNCTION GROWTH AND PREDISPOSE TO CHRONIC NON-MALIGNANT LUNG DISEASES. THESE EXPOSURES GENERALLY INTERACT WITH A GENETIC PREDISPOSITION, AND GENE-ENVIRONMENT INTERACTIONS AND EPIGENETIC PHENOMENA ARE ATTRACTING CONSIDERABLE STUDY. AN UNDERSTANDING OF HOW AMBIENT EXPOSURES IMPACT ON NORMAL LUNG GROWTH AND DEVELOPMENT WILL AID IN UNDERSTANDING OF HOW CHRONIC RESPIRATORY DISEASES OF ADULTS DEVELOP AND MAY LEAD TO NEW PREVENTATIVE STRATEGIES.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
15 4266  36 MICRO-RNAS: CROSSROADS BETWEEN THE EXPOSURE TO ENVIRONMENTAL PARTICULATE POLLUTION AND THE OBSTRUCTIVE PULMONARY DISEASE. ENVIRONMENTAL POLLUTION HAS REACHED A GLOBAL ECHO AND REPRESENTS A SERIOUS PROBLEM FOR HUMAN HEALTH. AIR POLLUTION ENCOMPASSES A SET OF HAZARDOUS SUBSTANCES, SUCH AS PARTICULATE MATTER AND HEAVY METALS (E.G., CADMIUM, LEAD, AND ARSENIC), AND HAS A STRONG IMPACT ON THE ENVIRONMENT BY AFFECTING GROUNDWATER, SOIL, AND AIR. AN ADAPTIVE RESPONSE TO ENVIRONMENTAL CUES IS ESSENTIAL FOR HUMAN SURVIVAL, WHICH IS ASSOCIATED WITH THE INDUCTION OF ADAPTIVE PHENOTYPES. THE EPIGENETIC MECHANISMS REGULATING THE EXPRESSION PATTERNS OF SEVERAL GENES ARE PROMISING CANDIDATES TO PROVIDE MECHANISTIC AND PROGNOSTIC INSIGHTS INTO THIS. MICRO-RNAS (MIRNAS) FULFIL THESE FEATURES GIVEN THEIR ABILITY TO RESPOND TO ENVIRONMENTAL FACTORS AND THEIR CRITICAL ROLE IN DETERMINING PHENOTYPES. THESE MOLECULES ARE PRESENT IN EXTRACELLULAR FLUIDS, AND THEIR EXPRESSION PATTERNS ARE ORGAN-, TISSUE-, OR CELL-SPECIFIC. MOREOVER, THE EXPERIMENTAL SETTINGS FOR THEIR QUANTITATIVE AND QUALITATIVE ANALYSIS ARE ROBUST, STANDARDIZED, AND INEXPENSIVE. IN THIS REVIEW, WE PROVIDE AN UPDATE ON THE ROLE OF MIRNAS AS SUITABLE TOOLS FOR UNDERSTANDING THE MECHANISMS BEHIND THE PHYSIOPATHOLOGICAL RESPONSE TO TOXICANTS AND THE PROGNOSTIC VALUE OF THEIR EXPRESSION PATTERN ASSOCIABLE WITH SPECIFIC EXPOSURES. WE LOOK AT THE MECHANISTIC EVIDENCE ASSOCIABLE TO THE ROLE OF MIRNAS IN THE PROCESSES LEADING TO ENVIRONMENTAL-INDUCED PULMONARY DISEASE (I.E., CHRONIC OBSTRUCTIVE PULMONARY DISEASE).	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16  298  48 AIR POLLUTION AND AIRWAY DISEASE. EPIDEMIOLOGICAL AND TOXICOLOGICAL RESEARCH CONTINUES TO SUPPORT A LINK BETWEEN URBAN AIR POLLUTION AND AN INCREASED INCIDENCE AND/OR SEVERITY OF AIRWAY DISEASE. DETRIMENTAL EFFECTS OF OZONE (O(3)), NITROGEN DIOXIDE (NO(2)) AND PARTICULATE MATTER (PM), AS WELL AS TRAFFIC-RELATED POLLUTION AS A WHOLE, ON RESPIRATORY SYMPTOMS AND FUNCTION ARE WELL DOCUMENTED. NOT ONLY DO WE HAVE STRONG EPIDEMIOLOGICAL EVIDENCE OF A RELATIONSHIP BETWEEN AIR POLLUTION AND EXACERBATION OF ASTHMA AND RESPIRATORY MORBIDITY AND MORTALITY IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), BUT RECENT STUDIES, PARTICULARLY IN URBAN AREAS, HAVE SUGGESTED A ROLE FOR POLLUTANTS IN THE DEVELOPMENT OF BOTH ASTHMA AND COPD. SIMILARLY, WHILE PREVALENCE AND SEVERITY OF ATOPIC CONDITIONS APPEAR TO BE MORE COMMON IN URBAN COMPARED WITH RURAL COMMUNITIES, EVIDENCE IS EMERGING THAT TRAFFIC-RELATED POLLUTANTS MAY CONTRIBUTE TO THE DEVELOPMENT OF ALLERGY. FURTHERMORE, NUMEROUS EPIDEMIOLOGICAL AND EXPERIMENTAL STUDIES SUGGEST AN ASSOCIATION BETWEEN EXPOSURE TO NO(2) , O(3) , PM AND COMBUSTION PRODUCTS OF BIOMASS FUELS AND AN INCREASED SUSCEPTIBILITY TO AND MORBIDITY FROM RESPIRATORY INFECTION. GIVEN THE CONSIDERABLE CONTRIBUTION THAT TRAFFIC EMISSIONS MAKE TO URBAN AIR POLLUTION RESEARCHERS HAVE SOUGHT TO CHARACTERIZE THE RELATIVE TOXICITY OF TRAFFIC-RELATED PM POLLUTANTS. RECENT ADVANCES IN MECHANISMS IMPLICATED IN THE ASSOCIATION OF AIR POLLUTANTS AND AIRWAY DISEASE INCLUDE EPIGENETIC ALTERATION OF GENES BY COMBUSTION-RELATED POLLUTANTS AND HOW POLYMORPHISMS IN GENES INVOLVED IN ANTIOXIDANT PATHWAYS AND AIRWAY INFLAMMATION CAN MODIFY RESPONSES TO AIR POLLUTION EXPOSURES. OTHER INTERESTING EPIDEMIOLOGICAL OBSERVATIONS RELATED TO INCREASED HOST SUSCEPTIBILITY INCLUDE A POSSIBLE LINK BETWEEN CHRONIC PM EXPOSURE DURING CHILDHOOD AND VULNERABILITY TO COPD IN ADULTHOOD, AND THAT INFANTS SUBJECTED TO HIGHER PRENATAL LEVELS OF AIR POLLUTION MAY BE AT GREATER RISK OF DEVELOPING RESPIRATORY CONDITIONS. WHILE THE CHARACTERIZATION OF POLLUTANT COMPONENTS AND SOURCES PROMISE TO GUIDE POLLUTION CONTROL STRATEGIES, THE IDENTIFICATION OF SUSCEPTIBLE SUBPOPULATIONS WILL BE NECESSARY IF TARGETED THERAPY/PREVENTION OF POLLUTION-INDUCED RESPIRATORY DISEASES IS TO BE DEVELOPED.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17 6876  44 [PROLONGED EXPOSURE TO ATMOSPHERIC AIR POLLUTION AND MORTALITY FROM RESPIRATORY CAUSES]. DIFFERENT DESIGNS CAN BE USED TO ANALYZE THE RELATIONSHIPS BETWEEN RESPIRATORY MORTALITY AND LONG TERM EXPOSURE TO ATMOSPHERIC POLLUTION: EPIDEMIOLOGICAL STUDIES (COHORT, PREVALENCE STUDY) DEMONSTRATE THE REALITY OF THE RELATIONSHIP AND TOXICOLOGICAL STUDIES EXPLAIN IT. COHORT STUDIES HAVE THE ADVANTAGE OF BEING ABLE TO TAKE INTO ACCOUNT MANY CONFOUNDING FACTORS AND THUS AVOID BIASES (WHICH IS NOT THE CASE WITH PREVALENCE STUDIES), BUT REQUIRE SIGNIFICANT HUMAN AND FINANCIAL RESOURCES. THEY WERE FIRST ADOPTED IN THE US, BUT ARE NOW MORE OFTEN APPLIED IN EUROPE. THE RESULTS ARE RELATIVELY CONSISTENT, AS THEY ALL SHOW A STATISTICALLY SIGNIFICANT ASSOCIATION BETWEEN AN INCREASE IN PARTICULATE POLLUTION AND CARDIOPULMONARY MORTALITY. MORTALITY FROM LUNG CANCER IS ALSO ASSOCIATED WITH LONG TERM EXPOSITION TO PARTICLES AND SOMETIMES TO OZONE OR NITROGEN OXIDES. CEREBROVASCULAR DISEASES AND SUDDEN DEATH OF YOUNG CHILDREN HAVE ALSO BEEN ASSOCIATED WITH PARTICULATE POLLUTION. THE RELATIONSHIPS ARE MORE POWERFUL FOR LONG TERM THAN SHORT TERM EXPOSURE BUT ARE ALSO LINEAR AND WITHOUT THRESHOLD. IN ORDER TO EXPLAIN THESE EFFECTS (TODAY THE CAUSALITY OF THE RELATIONSHIP IS CERTAIN) THERE ARE MANY POSSIBLE FACTORS, PARTICULARLY REGARDING PARTICULATE EXPOSURES: AN INCREASE IN CARDIOVASCULAR RISK BIOMARKERS (FIBRINOGEN, WHITE BLOOD CELLS, AND PLATELETS), ATHEROSCLEROSIS, CHRONIC INFLAMMATION OF LUNG TISSUES INCREASED BY ACUTE EXPOSURE, ETC. MORE AND MORE STUDIES ADDRESS THE INTERACTION BETWEEN GENE AND ENVIRONMENT AND EVEN EPIGENETIC PHENOMENA WHICH COULD BE RESPONSIBLE OF THESE EFFECTS. PUBLIC HEALTH IMPACT COULD BE QUANTIFIED. THE EUROPEAN E&H SURVEILLANCE PROGRAM APHEIS, FOR EXAMPLE, ESTIMATED THAT IF PM2.5 LEVELS REMAINED BELOW 15 MICROG/M(3), A 30 YEAR OLD PERSON COULD SEE HIS LIFE EXPECTANCY INCREASED BY 1 MONTH TO 2 YEARS, DEPENDING ON THE STUDIED CITY. FINALLY, MORTALITY IS NOT THE ONLY RELEVANT INDICATOR FOR HEALTH EFFECTS OF AIR POLLUTION. ISAAC STUDIES ADDRESS ASTHMA, ALLERGIC RHINITIS AND ECZEMA AMONG CHILDREN.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
18 6909  42 [TOXIC COMPONENTS OF PM(2.5) AND THEIR TOXICITY MECHANISMS-ON THE TOXICITY OF SULFATE AND CARBON COMPONENTS]. RECENTLY, THE MAIN AIR POLLUTANT HAS BEEN FINE PARTICULATE MATTER (PM(2.5)), WHICH IS TAKEN UP BY THE WHOLE BODY WITH SEVERE ADVERSE HEALTH EFFECTS. THE MAIN CHEMICAL COMPONENTS OF PM(2.5) ARE SALTS OF SULFATE (AND NITRATE) AND CARBONS. HOWEVER, IT REMAINS UNKNOWN WHICH COMPONENTS ARE TOXIC. HERE, THE AUTHOR REVIEWED THE LITERATURES TO DETERMINE WHICH COMPONENTS ARE TOXIC AND THE MAIN MECHANISMS UNDERLYING THEIR TOXICITY. MANY EPIDEMIOLOGICAL STUDIES HAVE SHOWN THAT SULFATE CONCENTRATION IS STRONGLY RELATED TO MORTALITY. HOWEVER, THERE IS NO EXPERIMENTAL EVIDENCE SHOWING THAT SULFATE AT ENVIRONMENTAL CONCENTRATIONS OF PM(2.5) CAUSES CARDIOVASCULAR DISEASE OR OTHER DISEASE. ON THE OTHER HAND, CARBON COMPONENTS SUCH AS ELEMENTARY CARBON (EC) PRODUCES HIGH CONCENTRATIONS OF REACTIVE OXYGEN SPECIES (ROS) VIA ITS PHAGOCYTOSIS BY MACROPHAGES, AND ORGANIC CARBON (OC) ALSO PRODUCES HIGH CONCENTRATIONS OF ROS DURING ITS METABOLIC PROCESSES, AND THE ROS CAUSE ACUTE AND CHRONIC INFLAMMATION. THEY CAUSE MANY DISEASES INCLUDING CARDIOVASCULAR DISEASE, ASTHMA AND CANCER. FURTHERMORE, THERE ARE MANY LINES OF EVIDENCE SHOWING THAT EPIGENETIC CHANGES SUCH AS DNA METHYLATION OR MICRORNA EXPRESSION INDUCED BY PARTICULATE MATTERS ALSO INDUCE THE DEVELOPMENT OF MANY DISEASES SUCH AS THOSE MENTIONED ABOVE. IT HAS BEEN REPORTED THAT CARBON COMPONENTS ARE INCORPORATED INTO THE BRAIN AND PRODUCE ROS, AND THAT THE ROS CAUSE DAMAGE TO BRAIN CELLS AND ALZHEIMER'S DISEASE AND COGNITIVE DISORDERS IN THE ELDERLY.FROM THESE LINES OF EVIDENCE, THE AUTHOR WOULD LIKE TO EMPHASIZE THAT THE MAIN TOXICITY OF PM(2.5) IS DUE TO CARBON COMPONENTS, AND IT IS IMPORTANT TO TAKE COUNTERMEASURES TO DECREASE THE CONCENTRATION OF CARBON COMPONENTS IN AMBIENT AIR.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19 6183  35 THE IMPACT OF ENVIRONMENTAL FACTORS IN INFLUENCING EPIGENETICS RELATED TO OXIDATIVE STATES IN THE CARDIOVASCULAR SYSTEM. OXIDATIVE STATES EXERT A SIGNIFICANT INFLUENCE ON A WIDE RANGE OF BIOLOGICAL AND MOLECULAR PROCESSES AND FUNCTIONS. WHEN THEIR BALANCE IS SHIFTED TOWARDS ENHANCED AMOUNTS OF FREE RADICALS, PATHOLOGICAL PHENOMENA CAN OCCUR, AS THE GENERATION OF REACTIVE OXYGEN SPECIES (ROS) IN TISSUE MICROENVIRONMENT OR IN THE SYSTEMIC CIRCULATION CAN BE DETRIMENTAL. EPIDEMIC CHRONIC DISEASES OF WESTERN SOCIETIES, SUCH AS CARDIOVASCULAR DISEASE, OBESITY, AND DIABETES CORRELATE WITH THE IMBALANCE OF REDOX HOMEOSTASIS. CURRENT ADVANCES IN OUR UNDERSTANDING OF EPIGENETICS HAVE REVEALED A PARALLEL SCENARIO SHOWING THE INFLUENCE OF OXIDATIVE STRESS AS A MAJOR REGULATOR OF EPIGENETIC GENE REGULATION VIA MODIFICATION OF DNA METHYLATION, HISTONES, AND MICRORNAS. THIS HAS PROVIDED BOTH THE BIOLOGICAL LINK AND A POTENTIAL MOLECULAR EXPLANATION BETWEEN OXIDATIVE STRESS AND CARDIOVASCULAR/METABOLIC PHENOMENA. ACCORDINGLY, IN THIS REVIEW, WE WILL PROVIDE CURRENT INSIGHTS ON THE PHYSIOLOGICAL AND PATHOLOGICAL IMPACT OF CHANGES IN OXIDATIVE STATES ON CARDIOVASCULAR DISORDERS, BY SPECIFICALLY FOCUSING ON THE INFLUENCE OF EPIGENETIC REGULATION. A SPECIAL EMPHASIS WILL HIGHLIGHT THE EFFECT ON EPIGENETIC REGULATION OF HUMAN'S CURRENT LIFE HABITS, EXTERNAL AND ENVIRONMENTAL FACTORS, INCLUDING FOOD INTAKE, TOBACCO, AIR POLLUTION, AND ANTIOXIDANT-BASED APPROACHES. ADDITIONALLY, THE STRATEGY TO QUANTIFY OXIDATIVE STATES IN HUMANS IN ORDER TO DETERMINE WHICH BIOLOGICAL MARKER COULD BEST MATCH A SUBJECT'S PROFILE WILL BE DISCUSSED.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
20 4881  39 OVERVIEW OF THE CARDIOVASCULAR EFFECTS OF ENVIRONMENTAL METALS: NEW PRECLINICAL AND CLINICAL INSIGHTS. ENVIRONMENTAL CAUSES OF CARDIOVASCULAR DISEASES (CVDS) ARE GLOBAL HEALTH ISSUES. IN PARTICULAR, AN ASSOCIATION BETWEEN METAL EXPOSURE AND CVDS HAS BECOME EVIDENT BUT CAUSAL EVIDENCE STILL LACKS. THEREFORE, THIS SYMPOSIUM AT THE SOCIETY OF TOXICOLOGY 2022 ANNUAL MEETING ADDRESSED EPIDEMIOLOGICAL, CLINICAL, PRE-CLINICAL ANIMAL MODEL-DERIVED AND MECHANISM-BASED EVIDENCE BY FIVE PRESENTATIONS: 1) AN EPIDEMIOLOGIC STUDY ON POTENTIAL CVD RISKS OF INDIVIDUALS EXPOSED OCCUPATIONALLY AND ENVIRONMENTALLY TO HEAVY METALS; 2) BOTH PRESENTATIONS OF THE SECOND AND THIRD WERE CLINICAL STUDIES FOCUSING ON THE POTENTIAL LINK BETWEEN HEAVY METALS AND PULMONARY ARTERIAL HYPERTENSION (PAH), BY PRESENTING ALTERED BLOOD METAL CONCENTRATIONS OF BOTH NON-ESSENTIAL AND ESSENTIAL METALS IN THE PATIENTS WITH PAH AND POTENTIAL THERAPEUTIC APPROACHES; 3) ARSENIC-INDUCED ATHEROSCLEROSIS VIA INFLAMMATORY CELLS IN MOUSE MODEL; 4) PATHOGENIC EFFECTS ON THE HEART BY ADULT CHRONIC EXPOSURE TO VERY LOW-DOSE CADMIUM VIA EPIGENETIC MECHANISMS AND WHOLE LIFE EXPOSURE TO LOW DOSE CADMIUM VIA EXACERBATING HIGH-FAT-DIET-LIPOTOXICITY. THIS SYMPOSIUM HAS BROUGHT EPIDEMIOLOGISTS, THERAPEUTIC INDUSTRY, PHYSICIANS, AND TRANSLATIONAL SCIENTISTS TOGETHER TO DISCUSS THE HEALTH RISKS OF OCCUPATIONAL AND ENVIRONMENTAL EXPOSURE TO HEAVY METALS THROUGH DIRECT CARDIOTOXICITY AND INDIRECT DISRUPTION OF HOMEOSTATIC MECHANISMS REGULATING ESSENTIAL METALS, AS WELL AS LIPID LEVELS. THE DATA SUMMARIZED BY THE PRESENTERS INFERS A POTENTIAL CAUSAL LINK BETWEEN MULTIPLE METALS AND CVDS AND DEFINES DIFFERENCES AND COMMONALITIES. THEREFORE, SUMMARY OF THESE PRESENTATIONS MAY ACCELERATE THE DEVELOPMENT OF EFFICIENT PREVENTIVE AND THERAPEUTIC STRATEGIES BY FACILITATING COLLABORATIONS AMONG MULTIDISCIPLINARY INVESTIGATORS.	2022
