1  108 121 A REVIEW OF THE PROTECTIVE EFFECT OF MELATONIN IN PESTICIDE-INDUCED TOXICITY. PESTICIDES ARE AMONG THE MOST IMPORTANT CHEMICALS USED IN AGRICULTURE SECTOR. HOWEVER, THEIR EXTENSIVE USE HAS POLLUTED THE ENVIRONMENT AND INCREASED HUMAN VULNERABILITY TO VARIOUS CHRONIC DISEASES. PESTICIDE EXPOSURE CAUSES GENETIC AND EPIGENETIC MODIFICATIONS, ENDOCRINE DISRUPTION, MITOCHONDRIAL DYSFUNCTION AND OXIDATIVE STRESS. AREAS COVERED: THIS REVIEW IS BASED ON THE LITERATURE STUDIES CURRENTLY REPORTED ON PESTICIDE-INDUCED TOXICITY AND THE PROTECTIVE ROLE OF MELATONIN. SCIENTIFIC DATABASES SUCH AS PUBMED, SCOPUS AND WEB OF SCIENCE WERE SEARCHED USING KEYWORDS 'PESTICIDE' AND 'MELATONIN' UP TO JANUARY 2016. FULL LENGTH ARTICLES RELATED TO ANIMAL AND HUMAN EXPOSURE WERE RETRIEVED. A TOTAL NUMBER OF 181 RECORDS WERE OBTAINED, AND AFTER EXCLUDING THE DUPLICATES, 97 PAPERS WERE FURTHER SCREENED ON THE BASIS OF RELEVANCE TO THE TOPIC. EXPERT OPINION: MELATONIN AS A BROAD-SPECTRUM ANTIOXIDANT IS ABLE TO PENETRATE CELLULAR COMPARTMENTS SPECIFICALLY THE MITOCHONDRIA. IT IS A POTENT FREE RADICAL SCAVENGER WITH LOW TOXICITY AND DESIRABLE SOLUBILITY IN ORGANIC AND AQUEOUS PHASES. WE ARE OF THE OPINION THAT MELATONIN IS A PROMISING AGENT IN MINIMIZING ORGAN INJURIES INDUCED BY PESTICIDES.	2017

3 1324  31 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
4 5194  38 PRENATAL EXPOSURE TO POTENTIALLY TOXIC METALS AND THEIR EFFECTS ON GENETIC MATERIAL IN OFFSPRING: A SYSTEMATIC REVIEW. IN RECENT YEARS, THE BACKGROUND LEVEL OF ENVIRONMENTAL POLLUTANTS, INCLUDING METALS, HAS INCREASED. POLLUTANT EXPOSURE DURING THE EARLIEST STAGES OF LIFE MAY DETERMINE CHRONIC DISEASE SUSCEPTIBILITY IN ADULTHOOD BECAUSE OF GENETIC OR EPIGENETIC CHANGES. THE OBJECTIVE OF THIS REVIEW WAS TO IDENTIFY THE ASSOCIATION BETWEEN PRENATAL AND EARLY POSTNATAL EXPOSURE TO POTENTIALLY TOXIC METALS (PTMS) AND THEIR ADVERSE EFFECTS ON THE GENETIC MATERIAL OF OFFSPRING. A SYSTEMATIC REVIEW WAS CARRIED OUT FOLLOWING THE COCHRANE METHODOLOGY IN FOUR DATABASES: PUBMED, SCOPUS, WEB OF SCIENCE, AND THE COCHRANE LIBRARY. ELIGIBLE PAPERS WERE THOSE CONDUCTED IN HUMANS AND PUBLISHED IN ENGLISH BETWEEN 2010/01/01 AND 2021/04/30. A TOTAL OF 57 ARTICLES WERE INCLUDED, MOST OF WHICH EVALUATED PRENATAL EXPOSURE. MOST COMMONLY EVALUATED PTMS WERE AS, CD, AND PB. MAIN ADVERSE EFFECTS ON THE GENETIC MATERIAL OF NEWBORNS ASSOCIATED WITH PTM PRENATAL EXPOSURE WERE ALTERATIONS IN TELOMERE LENGTH, GENE OR PROTEIN EXPRESSION, MITOCHONDRIAL DNA CONTENT, METABOLOMICS, DNA DAMAGE, AND EPIGENETIC MODIFICATIONS. MANY OF THESE EFFECTS WERE SEX-SPECIFIC, BEING PREDOMINANT IN BOYS. ONE ARTICLE REPORTED A SYNERGISTIC INTERACTION BETWEEN AS AND HG, AND TWO ARTICLES OBSERVED ANTAGONISTIC INTERACTIONS BETWEEN PTMS AND ESSENTIAL METALS, SUCH AS CU, SE, AND ZN. THE FINDINGS IN THIS REVIEW HIGHLIGHT THAT THE PROBLEM OF PTM EXPOSURE PERSISTS, AFFECTING THE MOST SUSCEPTIBLE POPULATIONS, SUCH AS NEWBORNS. SOME OF THESE ASSOCIATIONS WERE OBSERVED AT LOW CONCENTRATIONS OF PTMS. MOST OF THE STUDIES HAVE FOCUSED ON SINGLE EXPOSURES; HOWEVER, THREE INTERACTIONS BETWEEN ESSENTIAL AND NONESSENTIAL METALS WERE OBSERVED, HIGHLIGHTING THAT METAL MIXTURES NEED MORE ATTENTION.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5 6211  28 THE INTERPLAY BETWEEN OXIDATIVE STRESS, EXERCISE, AND PAIN IN HEALTH AND DISEASE: POTENTIAL ROLE OF AUTONOMIC REGULATION AND EPIGENETIC MECHANISMS. OXIDATIVE STRESS CAN BE INDUCED BY VARIOUS STIMULI AND ALTERED IN CERTAIN CONDITIONS, INCLUDING EXERCISE AND PAIN. ALTHOUGH MANY STUDIES HAVE INVESTIGATED OXIDATIVE STRESS IN RELATION TO EITHER EXERCISE OR PAIN, THE LITERATURE PRESENTS CONFLICTING RESULTS. THEREFORE, THIS REVIEW CRITICALLY DISCUSSES EXISTING LITERATURE ABOUT THIS TOPIC, AIMING TO PROVIDE A CLEAR OVERVIEW OF KNOWN INTERACTIONS BETWEEN OXIDATIVE STRESS, EXERCISE, AND PAIN IN HEALTHY PEOPLE AS WELL AS IN PEOPLE WITH CHRONIC PAIN, AND TO HIGHLIGHT POSSIBLE CONFOUNDING FACTORS TO KEEP IN MIND WHEN REFLECTING ON THESE INTERACTIONS. IN ADDITION, AUTONOMIC REGULATION AND EPIGENETIC MECHANISMS ARE PROPOSED AS POTENTIAL MECHANISMS OF ACTION UNDERLYING THE INTERPLAY BETWEEN OXIDATIVE STRESS, EXERCISE, AND PAIN. THIS REVIEW HIGHLIGHTS THAT THE RELATION BETWEEN OXIDATIVE STRESS, EXERCISE, AND PAIN IS POORLY UNDERSTOOD AND NOT STRAIGHTFORWARD, AS IT IS DEPENDENT ON THE CHARACTERISTICS OF EXERCISE, BUT ALSO ON WHICH POPULATION IS INVESTIGATED. TO BE ABLE TO COMPARE STUDIES ON THIS TOPIC, STRICT GUIDELINES SHOULD BE DEVELOPED TO LIMIT THE EFFECT OF SEVERAL CONFOUNDING FACTORS. THIS WAY, THE TRUE INTERPLAY BETWEEN OXIDATIVE STRESS, EXERCISE, AND PAIN, AND THE UNDERLYING MECHANISMS OF ACTION CAN BE REVEALED AND VALIDATED VIA INDEPENDENT STUDIES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
6 4805  35 OBESITY AND METABOLIC COMORBIDITIES: ENVIRONMENTAL DISEASES? OBESITY AND METABOLIC COMORBIDITIES REPRESENT INCREASING HEALTH PROBLEMS. ENDOCRINE DISRUPTING COMPOUNDS (EDCS) ARE EXOGENOUS AGENTS THAT CHANGE ENDOCRINE FUNCTION AND CAUSE ADVERSE HEALTH EFFECTS. MOST EDCS ARE SYNTHETIC CHEMICALS; SOME ARE NATURAL FOOD COMPONENTS AS PHYTOESTROGENS. PEOPLE ARE EXPOSED TO COMPLEX MIXTURES OF CHEMICALS THROUGHOUT THEIR LIVES. EDCS IMPACT HORMONE-DEPENDENT METABOLIC SYSTEMS AND BRAIN FUNCTION. LABORATORY AND HUMAN STUDIES PROVIDE COMPELLING EVIDENCE THAT HUMAN CHEMICAL CONTAMINATION CAN PLAY A ROLE IN OBESITY EPIDEMIC. CHEMICAL EXPOSURES MAY INCREASE THE RISK OF OBESITY BY ALTERING THE DIFFERENTIATION OF ADIPOCYTES. EDCS CAN ALTER METHYLATION PATTERNS AND NORMAL EPIGENETIC PROGRAMMING IN CELLS. OXIDATIVE STRESS MAY BE INDUCED BY MANY OF THESE CHEMICALS, AND ACCUMULATING EVIDENCE INDICATES THAT IT PLAYS IMPORTANT ROLES IN THE ETIOLOGY OF CHRONIC DISEASES. THE INDIVIDUAL SENSITIVITY TO CHEMICALS IS VARIABLE, DEPENDING ON ENVIRONMENT AND ABILITY TO METABOLIZE HAZARDOUS CHEMICALS. A NUMBER OF GENES, ESPECIALLY THOSE REPRESENTING ANTIOXIDANT AND DETOXIFICATION PATHWAYS, HAVE POTENTIAL APPLICATION AS BIOMARKERS OF RISK ASSESSMENT. THE POTENTIAL HEALTH EFFECTS OF COMBINED EXPOSURES MAKE THE RISK ASSESSMENT PROCESS MORE COMPLEX COMPARED TO THE ASSESSMENT OF SINGLE CHEMICALS. TECHNIQUES AND METHODS NEED TO BE FURTHER DEVELOPED TO FILL DATA GAPS AND INCREASE THE KNOWLEDGE ON HARMFUL EXPOSURE COMBINATIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
7  637  27 BIOLOGY OF PREMATURE AGEING IN SURVIVORS OF CANCER. OVER 30 MILLION CANCER SURVIVORS EXIST WORLDWIDE. SURVIVORS HAVE AN EARLIER ONSET AND HIGHER INCIDENCE OF CHRONIC COMORBIDITIES, INCLUDING ENDOCRINOPATHIES, CARDIAC DYSFUNCTION, OSTEOPOROSIS, PULMONARY FIBROSIS, SECONDARY CANCERS AND FRAILTY THAN THE GENERAL POPULATION; HOWEVER, THE FUNDAMENTAL BASIS OF THESE CHANGES AT THE CELLULAR LEVEL IS UNKNOWN. AN ELECTRONIC SEARCH WAS PERFORMED ON EMBASE, MEDLINE IN-PROCESS & OTHER NON-INDEXED CITATIONS, AND THE COCHRANE CENTRAL REGISTER OF CONTROLLED TRIALS. ORIGINAL ARTICLES ADDRESSING THE CELLULAR BIOLOGY OF AGEING AND/OR THE MECHANISMS OF CANCER THERAPIES SIMILAR TO AGEING MECHANISMS WERE INCLUDED, AND REFERENCES OF THESE ARTICLES WERE REVIEWED FOR FURTHER SEARCH. WE FOUND MULTIPLE BIOLOGICAL PROCESS OF AGEING AT THE CELLULAR LEVEL AND THEIR ASSOCIATION WITH CANCER THERAPIES, AS WELL AS WITH CLINICAL EFFECTS. THE DIRECT EFFECTS OF VARIOUS CHEMOTHERAPIES AND RADIATION ON TELOMERE LENGTH, SENESCENT CELLS, EPIGENETIC MODIFICATIONS AND MICRORNA WERE FOUND. WE REVIEW THE EFFECTS OF CANCER THERAPIES ON RECOGNISED HALLMARKS OF AGEING. LONG-TERM COMORBIDITIES SEEN IN CANCER SURVIVORS MIMIC THE PHENOTYPES OF AGEING AND LIKELY RESULT FROM THE INTERACTION BETWEEN THERAPEUTIC EXPOSURES AND THE UNDERLYING BIOLOGY OF AGEING. LONG-TERM FOLLOW-UP OF CANCER SURVIVORS AND RESEARCH ON PREVENTION STRATEGIES SHOULD BE PURSUED TO INCREASE THE LENGTH AND QUALITY OF LIFE AMONG THE GROWING POPULATION OF CANCER SURVIVORS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
8 2213  32 EPIGENETIC MODIFICATIONS AS OUTCOMES OF EXERCISE INTERVENTIONS RELATED TO SPECIFIC METABOLIC ALTERATIONS: A SYSTEMATIC REVIEW. BACKGROUND: CHRONIC DISEASES ARISE AS A CONSEQUENCE OF AN UNHEALTHY LIFESTYLE PRIMARILY CHARACTERIZED BY PHYSICAL INACTIVITY AND UNBALANCED DIETS. REGULAR PHYSICAL ACTIVITY CAN IMPROVE HEALTH, AND THERE IS CONSISTENT EVIDENCE THAT THESE IMPROVEMENTS MAY BE THE RESULT OF EPIGENETIC MODIFICATIONS. OBJECTIVE: TO IDENTIFY EPIGENETIC MODIFICATIONSAS OUTCOMES OF EXERCISE INTERVENTIONS RELATED TO SPECIFIC METABOLIC ALTERATIONS. METHODS: THE PREFERRED REPORTING ITEMS FOR SYSTEMATIC REVIEWS AND META-ANALYSES PROTOCOLS (PRISMA-P) METHODOLOGY FOR MANUSCRIPT RESEARCH AND PREPARATION WAS FOLLOWED USING PUBMED AND EBSCO DATABASES FOR LITERATURE REVIEW. OUT OF 2,638 ARTICLES IDENTIFIED, ONLY 34 ARTICLES MET THE INCLUSION CRITERIA. RESULTS: THE SECTIONS OF THE REVIEW WERE ORGANIZED BY METABOLIC ALTERATIONS IN WHICH STUDIES WERE GROUPED ACCORDING TO HEALTHY, DISEASED, AND TRAINED INDIVIDUALS. RESISTANCE EXERCISE IN HUMANS INDUCED EPIGENETIC CHANGES IN PATHWAYS ASSOCIATED WITH ENERGY METABOLISM AND INSULIN SENSITIVITY, CONTRIBUTING TO HEALTHY SKELETAL MUSCLE. ENDURANCE EXERCISE ALSO CAUSED MODIFICATIONS IN BIOMARKERS ASSOCIATED TO METABOLIC ALTERATIONS THROUGH CHANGES IN DNA METHYLATION AND THE EXPRESSION OF SPECIFIC MIRNAS. HOWEVER, BOTH RESISTANCE AND ENDURANCE EXERCISE ARE NECESSARY TO OBTAIN A BETTER PHYSIOLOGICAL ADAPTATION AND A COMBINATION OF BOTH SEEMS TO BE NEEDED TO PROPERLY TACKLE THE INCREASING PREVALENCE OF NON-COMMUNICABLE PATHOLOGIES. CONCLUSION: GIVEN THE HETEROGENEITY AND COMPLEXITY OF THE EXISTING LITERATURE, IT IS CURRENTLY NOT POSSIBLE TO PROPOSE A SPECIFIC RECOMMENDATION ABOUT THE TYPE, INTENSITY, OR DURATION OF EXERCISE THAT COULD BE BENEFICIAL FOR DIFFERENT SUBSETS OF THE POPULATION (HEALTHY, DISEASED, AND/OR TRAINED). NEVERTHELESS, THIS REVIEW HIGHLIGHTS THE IMPORTANCE OF EXERCISE FOR HEALTH AND SHOWS THE NEED TO PERFORM MORE RESEARCH IN THIS EMERGING AREA TO IDENTIFY EPIGENETIC BIOMARKERS THAT COULD SERVE AS INDICATORS OF EXERCISE ADAPTATIONS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9  228  30 ADAPTATION OF THE HUMAN POPULATION TO THE ENVIRONMENT: CURRENT KNOWLEDGE, CLUES FROM CZECH CYTOGENETIC AND "OMICS" BIOMONITORING STUDIES AND POSSIBLE MECHANISMS. THE HUMAN POPULATION IS CONTINUALLY EXPOSED TO NUMEROUS HARMFUL ENVIRONMENTAL STRESSORS, CAUSING NEGATIVE HEALTH EFFECTS AND/OR DEREGULATION OF BIOMARKER LEVELS. HOWEVER, STUDIES REPORTING NO OR EVEN POSITIVE IMPACTS OF SOME STRESSORS ON HUMANS ARE ALSO SOMETIMES PUBLISHED. THE MAIN AIM OF THIS REVIEW IS TO PROVIDE A COMPREHENSIVE OVERVIEW OF THE LAST DECADE OF CZECH BIOMONITORING RESEARCH, CONCERNING THE EFFECT OF VARIOUS LEVELS OF AIR POLLUTION (BENZO[A]PYRENE) AND RADIATION (URANIUM, X-RAY EXAMINATION AND NATURAL RADON BACKGROUND), ON THE DIFFERENTLY EXPOSED POPULATION GROUPS. BECAUSE SOME RESULTS OBTAINED FROM CYTOGENETIC STUDIES WERE OPPOSITE THAN HYPOTHESIZED, WE HAVE SEARCHED FOR A MEANINGFUL INTERPRETATION IN GENOMIC/EPIGENETIC STUDIES. A DETAILED ANALYSIS OF OUR DATA SUPPORTED BY THE STUDIES OF OTHERS AND CURRENT EPIGENETIC KNOWLEDGE, LEADS TO A HYPOTHESIS OF THE VERSATILE MECHANISM OF ADAPTATION TO ENVIRONMENTAL STRESSORS VIA DNA METHYLATION SETTINGS WHICH MAY EVEN ORIGINATE IN PRENATAL DEVELOPMENT, AND HELP TO REDUCE THE RESULTING DNA DAMAGE LEVELS. THIS HYPOTHESIS IS FULLY IN AGREEMENT WITH UNEXPECTED DATA FROM OUR STUDIES (E.G. LOWER LEVELS OF DNA DAMAGE IN SUBJECTS FROM HIGHLY POLLUTED REGIONS THAN IN CONTROLS OR IN SUBJECTS EXPOSED REPEATEDLY TO A POLLUTANT THAN IN THOSE WITHOUT PREVIOUS EXPOSURE), AND IS ALSO SUPPORTED BY DIFFERENCES IN DNA METHYLATION PATTERNS IN GROUPS FROM REGIONS WITH VARIOUS LEVELS OF POLLUTION. IN LIGHT OF THE ADAPTATION HYPOTHESIS, THE FOLLOWING POINTS MAY BE SUGGESTED FOR FUTURE RESEARCH: (I) THE CHRONIC AND ACUTE EXPOSURE OF STUDY SUBJECTS SHOULD BE DISTINGUISHED; (II) THE EXPOSURE HISTORY SHOULD BE MAPPED INCLUDING PLACE OF RESIDENCE DURING THE LIFE AND PRENATAL DEVELOPMENT; (III) CHANGES OF EPIGENETIC MARKERS SHOULD BE MONITORED OVER TIME. IN SUMMARY, INVESTIGATION OF HUMAN ADAPTATION TO THE ENVIRONMENT, ONE OF THE MOST IMPORTANT PROCESSES OF SURVIVAL, IS A NEW CHALLENGE FOR FUTURE RESEARCH IN THE FIELD OF HUMAN BIOMONITORING THAT MAY CHANGE OUR VIEW ON THE RESULTS OF BIOMARKER ANALYSES AND POTENTIAL NEGATIVE HEALTH IMPACTS OF THE ENVIRONMENT.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
10 6781  36 [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	

11 1932  21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12 6295  33 THE PROMISES AND CHALLENGES OF TOXICO-EPIGENOMICS: ENVIRONMENTAL CHEMICALS AND THEIR IMPACTS ON THE EPIGENOME. BACKGROUND: IT HAS BEEN ESTIMATED THAT A SUBSTANTIAL PORTION OF CHRONIC AND NONCOMMUNICABLE DISEASES CAN BE CAUSED OR EXACERBATED BY EXPOSURE TO ENVIRONMENTAL CHEMICALS. MULTIPLE LINES OF EVIDENCE INDICATE THAT EARLY LIFE EXPOSURE TO ENVIRONMENTAL CHEMICALS AT RELATIVELY LOW CONCENTRATIONS COULD HAVE LASTING EFFECTS ON INDIVIDUAL AND POPULATION HEALTH. ALTHOUGH THE POTENTIAL ADVERSE EFFECTS OF ENVIRONMENTAL CHEMICALS ARE KNOWN TO THE SCIENTIFIC COMMUNITY, REGULATORY AGENCIES, AND THE PUBLIC, LITTLE IS KNOWN ABOUT THE MECHANISTIC BASIS BY WHICH THESE CHEMICALS CAN INDUCE LONG-TERM OR TRANSGENERATIONAL EFFECTS. TO ADDRESS THIS QUESTION, EPIGENETIC MECHANISMS HAVE EMERGED AS THE POTENTIAL LINK BETWEEN GENETIC AND ENVIRONMENTAL FACTORS OF HEALTH AND DISEASE. OBJECTIVES: WE PRESENT AN OVERVIEW OF EPIGENETIC REGULATION AND A SUMMARY OF REPORTED EVIDENCE OF ENVIRONMENTAL TOXICANTS AS EPIGENETIC DISRUPTORS. WE ALSO DISCUSS THE ADVANTAGES AND CHALLENGES OF USING EPIGENETIC BIOMARKERS AS AN INDICATOR OF TOXICANT EXPOSURE, USING MEASURES THAT CAN BE TAKEN TO IMPROVE RISK ASSESSMENT, AND OUR PERSPECTIVES ON THE FUTURE ROLE OF EPIGENETICS IN TOXICOLOGY. DISCUSSION: UNTIL RECENTLY, EFFORTS TO APPLY EPIGENOMIC DATA IN TOXICOLOGY AND RISK ASSESSMENT WERE RESTRICTED BY AN INCOMPLETE UNDERSTANDING OF EPIGENOMIC VARIABILITY ACROSS TISSUE TYPES AND POPULATIONS. THIS IS POISED TO CHANGE WITH THE DEVELOPMENT OF NEW TOOLS AND CONCERTED EFFORTS BY RESEARCHERS ACROSS DISCIPLINES THAT HAVE LED TO A BETTER UNDERSTANDING OF EPIGENETIC MECHANISMS AND COMPREHENSIVE MAPS OF EPIGENOMIC VARIATION. WITH THE FOUNDATIONS NOW IN PLACE, WE FORESEE THAT UNPRECEDENTED ADVANCEMENTS WILL TAKE PLACE IN THE FIELD IN THE COMING YEARS.

13 1998  31 EPIGENETIC AND MIRNA EXPRESSION CHANGES IN PEOPLE WITH PAIN: A SYSTEMATIC REVIEW. ACCUMULATING EVIDENCE SUGGESTS THAT EPIGENETIC MECHANISMS MAY HOLD GREAT POTENTIAL IN THE FIELD OF PAIN. WE SYSTEMATICALLY REVIEWED THE LITERATURE EXPLORING EPIGENETIC MECHANISMS IN PEOPLE WITH PAIN. FOUR DATABASES HAVE BEEN INTERROGATED: MEDLINE, THE COCHRANE CENTRAL REGISTER OF CONTROLLED TRIAL, SCOPUS, AND WEB OF SCIENCE, FOLLOWING PRISMA GUIDELINES IN CONDUCTING STUDY SELECTION AND ASSESSMENT. THIRTY-SEVEN STUDIES WERE INCLUDED. STUDIES EXPLORED EPIGENETICS IN CONDITIONS SUCH AS FIBROMYALGIA, CRPS, NEUROPATHIES, OR OSTEOARTHRITIS. RESEARCH FOCUSSED ON GENOME-WIDE AND GENE-SPECIFIC DNA METHYLATION, AND MIRNA EXPRESSION. BIOINFORMATICS ANALYSES EXPLORING MIRNA-ASSOCIATED MOLECULAR PATHWAYS WERE ALSO PERFORMED. SEVERAL GENES ALREADY KNOWN FOR THEIR ROLE IN PAIN (BDNF, HDAC4, PRKG1, IL-17, TNFRSF13B, ETC.), AND SEVERAL MIRNAS LINKED TO INFLAMMATORY REGULATION, NOCICEPTIVE SIGNALLING AND PROTEIN KINASES FUNCTIONS HAVE BEEN FOUND TO DIFFER SIGNIFICANTLY BETWEEN PEOPLE WITH CHRONIC PAIN AND HEALTHY CONTROLS. ALTHOUGH THE STUDIES INCLUDED WERE CROSS-SECTIONAL IN NATURE, AND NO CONCLUSION ON CAUSAL LINKS BETWEEN EPIGENETIC CHANGES AND PAIN COULD BE DRAWN, WE SUMMARISED THE LARGE AMOUNT OF DATA AVAILABLE IN LITERATURE ON THE TOPIC, HIGHLIGHTING RESULTS THAT HAVE BEEN REPLICATED BY INDEPENDENT INVESTIGATIONS. THE FIELD OF PAIN EPIGENETICS APPEARS VERY EXCITING AND HAS ALL THE POTENTIAL TO LEAD TO REMARKABLE SCIENTIFIC ADVANCES. HOWEVER, HIGH-QUALITY, WELL-POWERED, LONGITUDINAL STUDIES ARE WARRANTED. PERSPECTIVE: THOUGH MORE HIGH-QUALITY RESEARCH IS NEEDED, AVAILABLE RESEARCH EXPLORING EPIGENETIC MECHANISMS OR MIRNAS IN PEOPLE WITH PAIN SHOWS THAT GENES REGULATING SYNAPTIC PLASTICITY AND EXCITABILITY, PROTEIN KINASES, AND ELEMENTS OF THE IMMUNE SYSTEM MIGHT HOLD GREAT POTENTIAL IN UNDERSTANDING THE PATHOPHYSIOLOGY OF DIFFERENT CONDITIONS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14 6458  31 TIME COURSE OF DNA METHYLATION IN PAIN CONDITIONS: FROM EXPERIMENTAL MODELS TO HUMANS. BACKGROUND AND OBJECTIVE: THROUGHOUT THE LAST DECADE, RESEARCH HAS UNCOVERED ASSOCIATIONS BETWEEN PAIN AND EPIGENETIC ALTERATIONS CAUSED BY ENVIRONMENTAL FACTORS. SPECIFICALLY, STUDIES HAVE DEMONSTRATED CORRELATIONS BETWEEN PAIN CONDITIONS AND ALTERED DNA METHYLATION PATTERNS. THUS, DNA METHYLATION HAS BEEN REVEALED AS A POSSIBLE MODULATOR OR CONTRIBUTOR TO PAIN CONDITIONS, PROVIDING A POTENTIAL THERAPEUTIC TARGET FOR TREATMENT BY DNA METHYLATION MODIFICATION. TO DEVELOP SUCH TREATMENTS, IT IS NECESSARY TO CLARIFY A WIDE NUMBER OF ASPECTS ON HOW DNA METHYLATION AFFECTS PAIN PERCEPTION; FIRST AND FOREMOST, THE TEMPORAL DYNAMICS. THE OBJECTIVE OF THE PRESENT REVIEW IS TO PROVIDE AN OVERVIEW OF CURRENT KNOWLEDGE ON TEMPORAL DYNAMICS OF DNA METHYLATION IN RESPONSE TO PAIN, AND TO INVESTIGATE IF A TIMEFRAME CAN BE ESTABLISHED BASED ON THE DATA OF CURRENTLY PUBLISHED STUDIES. DATABASES AND DATA TREATMENT: PUBMED, MEDLINE, GOOGLE SCHOLAR AND EMBASE WERE SEARCHED COMPREHENSIVELY FOR STUDIES OF DNA METHYLATION IN NEUROPATHIC, INFLAMMATORY AND ALTERNATIVE ANIMAL PAIN MODELS, AND IN CHRONIC PAIN PATIENTS INCLUDING COMPLEX REGIONAL PAIN SYNDROME, CHRONIC POSTSURGICAL PAIN, CHRONIC WIDESPREAD PAIN, FIBROMYALGIA AND CROHN'S DISEASE. RESULTS: WE IDENTIFIED 34 ARTICLES HIGHLIGHTING VARIATIONS IN TEMPORAL DYNAMICS OF DNA METHYLATION ACROSS SPECIES AND BETWEEN DIFFERENT TYPES OF PAIN. THESE STUDIES REPRESENT A STARTING POINT TO UNCOVER NEW INSIGHTS IN THE DNA METHYLATION TIME COURSE IN PAIN.

15 6159  32 THE GENETICS AND EPIGENETICS OF FATIGUE. FATIGUE IS A COMMON SYMPTOM AND INCLUDES BOTH PHYSICAL AND MENTAL COMPONENTS. IT CAN BE ASSOCIATED WITH A VARIETY OF DIFFERENT SYNDROMES AND DISEASES, BUT IN MANY CASES IS NOT ASSOCIATED WITH OTHER COMORBID CONDITIONS. MOST HUMANS HAVE EXPERIENCED ACUTE FATIGUE IN RELATION TO DIFFERENT STRESSORS. ACUTE FATIGUE TYPICALLY DECREASES AS THE EFFECT OF THE TRIGGERING FACTOR IS REDUCED AND A NORMAL HOMEOSTATIC BALANCE IS RESTORED. FATIGUE THAT PERSISTS FOR 6 MONTHS OR MORE IS TERMED CHRONIC FATIGUE. CHRONIC FATIGUE (CF) IN COMBINATION WITH A MINIMUM OF 4 OF 8 SYMPTOMS AND THE ABSENCE OF DISEASES THAT COULD EXPLAIN THESE SYMPTOMS, CONSTITUTE THE CASE DEFINITION FOR CHRONIC FATIGUE SYNDROME. IN SPITE OF ITS PREVALENCE, THE BIOLOGY OF FATIGUE IS RELATIVELY POORLY UNDERSTOOD AND BIOLOGICAL MARKERS HAVE NOT YET BEEN IDENTIFIED. THIS LITERATURE SEARCH WAS PERFORMED IN PUBMED TO IDENTIFY RESEARCH ON THE GENETICS AND EPIGENETICS OF FATIGUE. PUBLICATIONS WERE INCLUDED IF FATIGUE WAS A MAJOR TOPIC AND THE TOPIC WAS COMBINED WITH GENETIC AND/OR EPIGENETIC MEASUREMENTS IN ADULT HUMANS. A TOTAL OF 40 PUBLICATIONS WERE IDENTIFIED. ALTHOUGH ALTERED FUNCTIONING IN THE HYPOTHALAMIC-PITUITARY-ADRENAL AXIS, THE SEROTONERGIC SYSTEM, AND ASSOCIATIONS WITH INFECTIOUS AGENTS HAVE BEEN IDENTIFIED, THE SEARCH FOR GENETIC OR EPIGENETIC MARKERS OF FATIGUE, EITHER IN THE CONTEXT OF CF OR CHRONIC FATIGUE SYNDROME (CFS) HAS BEEN RELATIVELY UNPRODUCTIVE OR, IN THE CASE OF EPIGENETICS, NONEXISTENT. ALTHOUGH SEVERAL STUDIES, BOTH HYPOTHESIS-TESTING AND HYPOTHESIS-GENERATING, HAVE BEEN PERFORMED TO SEARCH FOR BIOMARKERS, THEY HAVE MOSTLY BEEN UNDERPOWERED, RESTRICTED BY THE HETEROGENEITY OF THE PHENOTYPE, OR LIMITED BY AN UNSYSTEMATIC STUDY DESIGN. TO BE ABLE TO CONFIRM THE HYPOTHESIS THAT RISK FOR, OR LEVELS OF, FATIGUE ARE INFLUENCED BY THE GENETIC OR EPIGENETIC BACKGROUND OF AN INDIVIDUAL, STUDIES NEED TO BE BASED ON LARGER SAMPLE SIZES WITH A MORE CLEARLY DEFINED PHENOTYPE. STUDIES NEED TO FOCUS NOT ONLY ON THE INFLUENCE OF A SINGLE ASPECT SUCH AS SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS) OR DIFFERENTIAL GENE EXPRESSION ON DISEASE RISK OR STATE, BUT ALSO ON THE SYSTEMS BIOLOGY BEHIND THE DISEASE IN COMBINATION WITH INFORMATION ON ENVIRONMENTAL INFLUENCES AND VALIDATION OF FINDINGS IN FUNCTIONAL STUDIES.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16 5450  40 REPRODUCTIVE TOXICITY OF COMBINED EFFECTS OF ENDOCRINE DISRUPTORS ON HUMAN REPRODUCTION. CONFLUENCE OF ENVIRONMENTAL, GENETIC, AND LIFESTYLE VARIABLES IS RESPONSIBLE FOR DETERIORATION OF HUMAN FECUNDITY. ENDOCRINE DISRUPTORS OR ENDOCRINE DISRUPTING CHEMICALS (EDCS) MAY BE FOUND IN A VARIETY OF FOODS, WATER, AIR, BEVERAGES, AND TOBACCO SMOKE. IT HAS BEEN DEMONSTRATED IN EXPERIMENTAL INVESTIGATIONS THAT A WIDE RANGE OF ENDOCRINE DISRUPTING CHEMICALS HAVE NEGATIVE EFFECTS ON HUMAN REPRODUCTIVE FUNCTION. HOWEVER, EVIDENCE ON THE REPRODUCTIVE CONSEQUENCES OF HUMAN EXPOSURE TO ENDOCRINE DISRUPTING CHEMICALS IS SPARSE AND/OR CONFLICTING IN THE SCIENTIFIC LITERATURE. THE COMBINED TOXICOLOGICAL ASSESSMENT IS A PRACTICAL METHOD FOR ASSESSING THE HAZARDS OF COCKTAILS OF CHEMICALS, CO-EXISTING IN THE ENVIRONMENT. THE CURRENT REVIEW PROVIDES A COMPREHENSIVE OVERVIEW OF STUDIES EMPHASIZING THE COMBINED TOXICITY OF ENDOCRINE DISRUPTING CHEMICALS ON HUMAN REPRODUCTION. ENDOCRINE DISRUPTING CHEMICALS INTERACT WITH EACH OTHER TO DISRUPT THE DIFFERENT ENDOCRINE AXES, RESULTING IN SEVERE GONADAL DYSFUNCTIONS. TRANSGENERATIONAL EPIGENETIC EFFECTS HAVE ALSO BEEN INDUCED IN GERM CELLS, MOSTLY THROUGH DNA METHYLATION AND EPIMUTATIONS. SIMILARLY, AFTER ACUTE OR CHRONIC EXPOSURE TO ENDOCRINE DISRUPTING CHEMICALS COMBINATIONS, INCREASED OXIDATIVE STRESS (OS), ELEVATED ANTIOXIDANT ENZYMATIC ACTIVITY, DISRUPTED REPRODUCTIVE CYCLE, AND REDUCED STEROIDOGENESIS ARE OFTEN REPORTED CONSEQUENCES. THE ARTICLE ALSO DISCUSSES THE CONCENTRATION ADDITION (CA) AND INDEPENDENT ACTION (IA) PREDICTION MODELS, WHICH REVEAL THE IMPORTANCE OF VARIOUS SYNERGISTIC ACTIONS OF ENDOCRINE DISRUPTING CHEMICALS MIXTURES. MORE CRUCIALLY, THIS EVIDENCE-BASED STUDY ADDRESSES THE RESEARCH LIMITATIONS AND INFORMATION GAPS, AS WELL AS PARTICULARLY PRESENTS THE FUTURE RESEARCH VIEWS ON COMBINED ENDOCRINE DISRUPTING CHEMICALS TOXICITY ON HUMAN REPRODUCTION.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17 2869  32 FUNCTIONAL FOODS AND HEALTH EFFECTS: A NUTRITIONAL BIOCHEMISTRY PERSPECTIVE. BACKGROUND: INCREASED CONSUMER S INTEREST IN HEALTH HAS DRIVEN THE DEVELOPMENT OF FOODS THAT OFFER SPECIFIC BENEFICIAL EFFECTS. THE LIST OF FOODS AND INGREDIENTS INCLUDES ESSENTIAL AND NON-ESSENTIAL NUTRIENTS, PLANT AND MARINE COMPONENTS, WHOLE FOODS, MICROORGANISMS, MICROALGAE AND TECHNOLOGICAL APPROACHES. TRADITIONALLY, HEALTH OUTCOMES FOCUSSED ON THE PREVENTION OF CHRONIC DISEASES BUT HEALTH TARGETS HAVE EXPANDED TO COVER AREAS SUCH AS BRAIN HEALTH, INFLAMMATION, EYE HEALTH, WOMEN S HEALTH, HEALTHY AGEING AND BEAUTY. OBJECTIVE: THIS REVIEW HIGHLIGHTS, FROM A NUTRITIONAL BIOCHEMISTRY PERSPECTIVE, DIFFERENTIAL ASPECTS ON DESIGNING AND INTERPRETING HUMAN STUDIES TO SUPPORT THE HEALTH EFFECTS OF FUNCTIONAL FOODS. RESULTS: DESPITE THE AVAILABLE EVIDENCE FROM IN VITRO, ANIMAL AND OBSERVATIONAL STUDIES, WELLDESIGNED HUMAN STUDIES ARE NECESSARY TO SUPPORT THE HEALTH EFFECTS OF FUNCTIONAL FOODS. INTERVENTION TRIALS WITH FOODS ARE COMPLEX AS THEY IMPLY LIMITATIONS DUE TO METHODOLOGICAL, FOOD-RELATED AND HOST-RELATED FACTORS. THE USE OF RESPONSIVE, VALIDATED AND CLINICALLY RELEVANT MARKERS BECOMES ESSENTIAL EVEN THOUGH THERE IS A LACK OF RELIABLE BIOMARKERS OF EXPOSURE FOR MANY BIOACTIVES. FURTHERMORE, THE EFFECT OF MODULATING FACTORS SUCH AS SUBCLINICAL INFLAMMATION, GUT MICROBIOTA AND GENETIC VARIABILITY SHOULD BE TAKEN INTO ACCOUNT. MULTIPLE INDICATORS MAY PROVIDE A MORE RELIABLE ALTERNATIVE TO ASSESS PHYSIOLOGICAL PROCESSES WHILE EMERGING BIOMARKERS (MICRORNAS, EPIGENETIC CHANGES) CONSTITUTE A PROMISING APPROACH. ADDITIONALLY, THE MAGNITUDE OF THE CHANGE IS CRITICAL TO SUPPORT ANY HEALTH EFFECT ALTHOUGH INTERVENTIONS MAY HAVE A LIMITED CLINICAL IMPACT BUT BE EPIDEMIOLOGICALLY RELEVANT. ALSO, BASED ON THE AVAILABLE DATA, THE PREMISE THAT BIOACTIVESCONTAINING FOODS ARE SAFE MAY BE QUESTIONABLE. CONCLUSION: AN INTEGRATED APPROACH INCLUDING MULTIPLE BIOMARKERS, GENETIC VARIABILITY, EFFECT OF GUT MICROBIOTA AND RISK/BENEFIT ASSESSMENT SHOULD BE USED TO SUPPORT THE POTENTIAL HEALTH EFFECTS OF FUNCTIONAL FOODS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
18 3577  30 IMPACT OF NUTRITION ON TELOMERE HEALTH: SYSTEMATIC REVIEW OF OBSERVATIONAL COHORT STUDIES AND RANDOMIZED CLINICAL TRIALS. DIET, PHYSICAL ACTIVITY, AND OTHER LIFESTYLE FACTORS HAVE BEEN IMPLICATED IN THE PATHOPHYSIOLOGY OF SEVERAL CHRONIC DISEASES, BUT ALSO IN A LOWER TOTAL MORTALITY AND LONGER LIFE EXPECTANCY. ONE OF THE MECHANISMS IN WHICH DIET CAN REDUCE THE RISK OF DISEASE IS WITH REGARD TO ITS IMPACT ON TELOMERES. TELOMERE LENGTH (TL) IS HIGHLY CORRELATED TO CHRONOLOGICAL AGE AND METABOLIC STATUS. INDIVIDUALS WITH SHORTER TELOMERES ARE AT HIGHER RISK OF CHRONIC DISEASES AND MORTALITY. DIET MAY INFLUENCE TL BY SEVERAL MECHANISMS SUCH AS REGULATING OXIDATIVE STRESS AND INFLAMMATION OR MODULATING EPIGENETIC REACTIONS. THE PRESENT SYSTEMATIC REVIEW AIMS TO EXAMINE THE RESULTS FROM EPIDEMIOLOGIC AND CLINICAL TRIALS CONDUCTED IN HUMANS EVALUATING THE ROLE OF NUTRIENTS, FOOD GROUPS, AND DIETARY PATTERNS ON TL. WE ALSO DISCUSS THE POSSIBLE MECHANISMS OF ACTION THAT INFLUENCE THIS PROCESS, WITH THE PERSPECTIVE THAT TL COULD BE A NOVEL BIOMARKER INDICATING THE RISK OF METABOLIC DISTURBANCES AND AGE-RELATED DISEASES. THE AVAILABLE EVIDENCE SUGGESTS THAT SOME ANTIOXIDANT NUTRIENTS, THE CONSUMPTION OF FRUITS AND VEGETABLES, AND MEDITERRANEAN DIET ARE MAINLY ASSOCIATED WITH LONGER TELOMERES. HOWEVER, MOST OF THE EVIDENCE IS BASED ON HIGH HETEROGENIC OBSERVATIONAL STUDIES AND VERY FEW RANDOMIZED CLINICAL TRIALS (RCTS). THEREFORE, THE ASSOCIATIONS SUMMARIZED IN THE PRESENT REVIEW NEED TO BE CONFIRMED WITH LARGER PROSPECTIVE COHORT STUDIES AND BETTER-DESIGNED RCTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
19 2900  23 GENDER BIAS IN THERAPEUTIC EFFORT: FROM RESEARCH TO HEALTH CARE. THERE ARE RELEVANT DIMENSIONS FROM A GENDER PERSPECTIVE RELATED TO THERAPEUTIC EFFORT. TO ILLUSTRATE AND DISCUSS POSSIBLE GENDER BIAS RELATED TO MEDICINES, THROUGH THE CONSUMPTION ANALYSIS IN WOMEN, THE PRESCRIPTION OF BIOLOGICAL DRUGS ACCORDING TO SEX, THE POTENTIAL GENDER INEQUALITY IN ADVERSE DRUG REACTIONS, AND RESEARCH WITH CLINICAL TRIALS, AS WELL AS THE DECISIONS OF INTERNATIONAL INSTITUTIONS IN THE MARKETING OF MEDICINAL PRODUCTS. THERE IS GREATER TENDENCY TO PRESCRIBE PAIN RELIEVERS, REGARDLESS OF PAIN, AND DRUGS FOR LOW INTENSITY DEPRESSIVE SYMPTOMS IN WOMEN THAN IN MEN. THE OPPOSITE OCCURS IN THE PRESCRIPTION OF STATINS AND ADEQUATE DOSES, AND WITH THE GREATER PROBABILITY OF PRESCRIBING ANTI-TUMOR NECROSIS FACTOR IN MEN THAN IN WOMEN WITH ANKYLOSING SPONDYLITIS, DESPITE A SIMILAR DISEASE BURDEN. ADVERSE DRUG REACTIONS ARE OBSERVED MORE FREQUENTLY IN WOMEN THAN IN MEN, WHERE DETERMINANTS SUCH AS BODY WEIGHT ARE HAVING LITTLE INFLUENCE ON THE DOSAGE. IT IS CURRENTLY SCARCELY CONSIDERED IN THE PRESCRIPTION THAT WOMEN HAVE DIFFERENCES IN THE ACTIVITY OF CYTOCHROME CYPP450 ENZYMES, WHICH CAN AFFECT THE LIVER'S METABOLISM RATE. THERE ARE EVEN IMMUNOLOGICAL, GENETIC AND EPIGENETIC EFFECTS (DUE TO HEREDITY AND UNEVEN GENE DOSING LOCATED IN THE X AND Y CHROMOSOMES) THAT CAN INFLUENCE THESE DIFFERENCES BY SEX. FINALLY, THROUGH CASES OF HORMONAL THERAPY CLINICAL TRIALS, A DRUG FOR WOMEN'S INHIBITED SEXUAL DESIRE AND A CONTRACEPTIVE FOR MEN, GENDER BIAS AND STEREOTYPES ARE SHOWN TO INFLUENCE A POTENTIAL GENERATION OF INEQUALITIES, ESPECIALLY IN ADVERSE DRUG REACTIONS TO THE DETRIMENT OF WOMEN. IN CONCLUSION, HEALTH PROFESSIONALS FREQUENTLY ATTRIBUTE PHYSICAL SYMPTOMS TO WOMEN'S EMOTIONALITY, INFLUENCING THEIR GREATER PRESCRIPTION OF SYMPTOMATIC DRUGS. WHETHER THE SAME REASON INFLUENCES THE LOWER PRESCRIPTION OF THERAPEUTIC DRUGS IN WOMEN THAN IN MEN SHOULD BE ANALYZED. THERE ARE BIOLOGICAL DETERMINANTS TO CONSIDER DUE TO THEIR INFLUENCE ON A GREATER PHARMACOLOGICAL TOXICITY IN WOMEN. CLINICAL TRIALS SHOULD IMPROVE ACCORDING TO THE GENDER RECOMMENDATIONS BY THE FOOD AND DRUGS ADMINISTRATION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20 3881  31 KETOGENIC DIETS AND THE NERVOUS SYSTEM: A SCOPING REVIEW OF NEUROLOGICAL OUTCOMES FROM NUTRITIONAL KETOSIS IN ANIMAL STUDIES. OBJECTIVES: KETOGENIC DIETS HAVE REPORTED EFFICACY FOR NEUROLOGICAL DYSFUNCTIONS; HOWEVER, THERE ARE LIMITED PUBLISHED HUMAN CLINICAL TRIALS ELUCIDATING THE MECHANISMS BY WHICH NUTRITIONAL KETOSIS PRODUCES THERAPEUTIC EFFECTS. THE PURPOSE OF THIS PRESENT STUDY WAS TO INVESTIGATE ANIMAL MODELS THAT REPORT VARIATIONS IN NERVOUS SYSTEM FUNCTION BY CHANGING FROM A STANDARD ANIMAL DIET TO A KETOGENIC DIET, SYNTHESISE THESE INTO BROAD THEMES, AND COMPARE THESE WITH MECHANISMS REPORTED AS TARGETS IN PAIN NEUROSCIENCE TO INFORM HUMAN CHRONIC PAIN TRIALS. METHODS: AN ELECTRONIC SEARCH OF SEVEN DATABASES WAS CONDUCTED IN JULY 2020. TWO INDEPENDENT REVIEWERS SCREENED STUDIES FOR ELIGIBILITY, AND DESCRIPTIVE OUTCOMES RELATING TO NERVOUS SYSTEM FUNCTION WERE EXTRACTED FOR A THEMATIC ANALYSIS, THEN SYNTHESISED INTO BROAD THEMES. RESULTS: IN TOTAL, 170 STUDIES FROM EIGHTEEN DIFFERENT DISEASE MODELS WERE IDENTIFIED AND GROUPED INTO FOURTEEN BROAD THEMES: ALTERATIONS IN CELLULAR ENERGETICS AND METABOLISM, BIOCHEMICAL, CORTICAL EXCITABILITY, EPIGENETIC REGULATION, MITOCHONDRIAL FUNCTION, NEUROINFLAMMATION, NEUROPLASTICITY, NEUROPROTECTION, NEUROTRANSMITTER FUNCTION, NOCICEPTION, REDOX BALANCE, SIGNALLING PATHWAYS, SYNAPTIC TRANSMISSION AND VASCULAR SUPPLY. DISCUSSION: THE MECHANISMS PRESENTED CENTRED AROUND THE REDUCTION OF INFLAMMATION AND OXIDATIVE STRESS AS WELL AS A REDUCTION IN NERVOUS SYSTEM EXCITABILITY. GIVEN THE MULTIPLE POTENTIAL MECHANISMS PRESENTED, IT IS LIKELY THAT MANY OF THESE ARE INVOLVED SYNERGISTICALLY AND UNDERGO ADAPTIVE PROCESSES WITHIN THE HUMAN BODY, AND CONTROLLED ANIMAL MODELS THAT LIMIT THE INVESTIGATION TO A PARTICULAR PATHWAY IN ISOLATION MAY REACH DIFFERING CONCLUSIONS. ATTENTION IS REQUIRED WHEN TRANSLATING THIS INFORMATION TO HUMAN CHRONIC PAIN POPULATIONS OWING TO THE LIMITATIONS OUTLINED FROM THE ANIMAL RESEARCH.	2022
