1 1347 180 HYPOXIA IN CNS PATHOLOGIES: EMERGING ROLE OF MIRNA-BASED NEUROTHERAPEUTICS AND YOGA BASED ALTERNATIVE THERAPIES. CELLULAR RESPIRATION IS A VITAL PROCESS FOR THE EXISTENCE OF LIFE. ANY CONDITION THAT RESULTS IN DEPRIVATION OF OXYGEN (ALSO TERMED AS HYPOXIA) MAY EVENTUALLY LEAD TO DELETERIOUS EFFECTS ON THE FUNCTIONING OF TISSUES. BRAIN BEING THE HIGHEST CONSUMER OF OXYGEN IS PRONE TO INCREASED RISK OF HYPOXIA-INDUCED NEUROLOGICAL INSULTS. THIS IN TURN HAS BEEN ASSOCIATED WITH MANY DISEASES OF CENTRAL NERVOUS SYSTEM (CNS) SUCH AS STROKE, ALZHEIMER'S, ENCEPHALOPATHY ETC. ALTHOUGH SEVERAL STUDIES HAVE INVESTIGATED THE PATHOPHYSIOLOGICAL MECHANISMS UNDERLYING ISCHEMIC/HYPOXIC CNS DISEASES, THE KNOWLEDGE ABOUT PROTECTIVE THERAPEUTIC STRATEGIES TO AMELIORATE THE AFFECTED NEURONAL CELLS IS MEAGER. THIS HAS AUGMENTED THE NEED TO IMPROVE OUR UNDERSTANDING OF THE HYPOXIC AND ISCHEMIC EVENTS OCCURRING IN THE BRAIN AND IDENTIFY NOVEL AND ALTERNATE TREATMENT MODALITIES FOR SUCH INSULTS. MICRORNA (MIRNAS), SMALL NON-CODING RNA MOLECULES, HAVE RECENTLY EMERGED AS POTENTIAL NEUROPROTECTIVE AGENTS AS WELL AS TARGETS, UNDER HYPOXIC CONDITIONS. THESE 18-22 NUCLEOTIDE LONG RNA MOLECULES ARE PROFUSELY PRESENT IN BRAIN AND OTHER ORGANS AND FUNCTION AS GENE REGULATORS BY CLEAVING AND SILENCING THE GENE EXPRESSION. IN BRAIN, THESE ARE KNOWN TO BE INVOLVED IN NEURONAL DIFFERENTIATION AND PLASTICITY. THEREFORE, TARGETING MIRNA EXPRESSION REPRESENTS A NOVEL THERAPEUTIC APPROACH TO INTERCEDE AGAINST HYPOXIC AND ISCHEMIC BRAIN INJURY. IN THE FIRST PART OF THIS REVIEW, WE WILL DISCUSS THE NEUROPHYSIOLOGICAL CHANGES CAUSED AS A RESULT OF HYPOXIA, FOLLOWED BY THE CONTRIBUTION OF HYPOXIA IN THE NEURODEGENERATIVE DISEASES. SECONDLY, WE WILL PROVIDE RECENT UPDATES AND INSIGHTS INTO THE ROLES OF MIRNA IN THE REGULATION OF GENES IN OXYGEN AND GLUCOSE DEPRIVED BRAIN IN ASSOCIATION WITH CIRCADIAN RHYTHMS AND HOW THESE CAN BE TARGETED AS NEUROPROTECTIVE AGENTS FOR CNS INJURIES. FINALLY, WE WILL EMPHASIZE ON ALTERNATE BREATHING OR YOGIC INTERVENTIONS TO OVERCOME THE HYPOXIA ASSOCIATED ANOMALIES THAT COULD ULTIMATELY LEAD TO IMPROVEMENT IN CEREBRAL PERFUSION.	2017	
                                                                                        
2 1881  23 REDUCED HYPOXIC VENTILATORY RESPONSE WITH PRESERVED BLOOD OXYGENATION IN YOGA TRAINEES AND HIMALAYAN BUDDHIST MONKS AT ALTITUDE: EVIDENCE OF A DIFFERENT ADAPTIVE STRATEGY? YOGA INDUCES LONG-TERM CHANGES IN RESPIRATORY FUNCTION AND CONTROL. WE TESTED WHETHER IT REPRESENTS A SUCCESSFUL STRATEGY FOR HIGH-ALTITUDE ADAPTATION. WE COMPARED VENTILATORY, CARDIOVASCULAR AND HEMATOLOGICAL PARAMETERS IN: 12 CAUCASIAN YOGA TRAINEES AND 12 CONTROL SEA-LEVEL RESIDENTS, AT BASELINE AND AFTER 2-WEEK EXPOSURE TO HIGH ALTITUDE (PYRAMID LABORATORY, NEPAL, 5,050 M), 38 ACTIVE LIFESTYLE HIGH-ALTITUDE NATIVES (SHERPAS) AND 13 CONTEMPLATIVE LIFESTYLE HIGH-ALTITUDE NATIVES WITH PRACTICE OF YOGA-LIKE RESPIRATORY EXERCISES (BUDDHIST MONKS) STUDIED AT 5,050 M. AT BASELINE, HYPOXIC VENTILATORY RESPONSE (HVR), RED BLOOD CELL COUNT AND HEMATOCRIT WERE LOWER IN CAUCASIAN YOGA TRAINEES THAN IN CONTROLS. AFTER 14 DAYS AT ALTITUDE, YOGA TRAINEES SHOWED SIMILAR OXYGEN SATURATION, BLOOD PRESSURE, RR INTERVAL COMPARED TO CONTROLS, BUT LOWER HVR (-0.44 +/- 0.08 VS. -0.98 +/- 0.21 L/MIN/M/%SAO(2), P < 0.05), MINUTE VENTILATION (8.3 +/- 0.9 VS. 10.8 +/- 1.6 L/MIN, P < 0.05), BREATHING RATE (INDICATING HIGHER VENTILATORY EFFICIENCY), AND LOWER RED BLOOD CELL COUNT, HEMOGLOBIN, HEMATOCRIT, ALBUMIN, ERYTHROPOIETIN AND SOLUBLE TRANSFERRIN RECEPTORS. HYPOXIC VENTILATORY RESPONSE IN MONKS WAS LOWER THAN IN SHERPAS (-0.23 +/- 0.05 VS. -0.63 +/- 0.09 L/MIN/M/%SAO(2), P < 0.05); VALUES WERE SIMILAR TO BASELINE DATA OF YOGA TRAINEES AND CAUCASIAN CONTROLS, RESPECTIVELY. RED BLOOD CELL COUNT AND HEMATOCRIT WERE LOWER IN MONKS AS COMPARED TO SHERPAS. IN CONCLUSION, CAUCASIAN SUBJECTS PRACTICING YOGA MAINTAIN A SATISFACTORY OXYGEN TRANSPORT AT HIGH ALTITUDE, WITH MINIMAL INCREASE IN VENTILATION AND WITH REDUCED HEMATOLOGICAL CHANGES, RESEMBLING HIMALAYAN NATIVES. RESPIRATORY ADAPTATIONS INDUCED BY THE PRACTICE OF YOGA MAY REPRESENT AN EFFICIENT STRATEGY TO COPE WITH ALTITUDE-INDUCED HYPOXIA.	2007	
                                                                                                                                                                                                                                                                             
3 1149  46 ENHANCEMENT OF CANCER STEM CELL SUSCEPTIBILITY TO CONVENTIONAL TREATMENTS THROUGH COMPLEMENTARY YOGA THERAPY: POSSIBLE CELLULAR AND MOLECULAR MECHANISMS. CANCER STEM CELLS (CSCS) ARE STEM-LIKE TUMOR POPULATIONS THAT ARE REPORTED TO CONTRIBUTE TOWARDS TUMOR GROWTH, MAINTENANCE AND RECURRENCE AFTER THERAPY. HYPOXIA INCREASES CSC FRACTION AND PROMOTES ACQUISITION OF A STEM-CELL-LIKE STATE. CANCER STEM CELLS ARE CRITICALLY DEPENDANT ON THE HYPOXIA-INDUCIBLE FACTOR-1 (HIF-1) FOR SURVIVAL, SELF-RENEWAL, TUMOR GROWTH AND MAINTENANCE OF THEIR UNDIFFERENTIATED PHENOTYPE. RECENT RESEARCHES SHOW THAT STAGE OF DIFFERENTIATION OF THE TUMOR CELLS IS PREDICTIVE OF THEIR SUSCEPTIBILITY TO NATURAL KILLER CELL (NK) CELL MEDIATED CYTOTOXICITY AND CANCER STEM CELLS ARE SIGNIFICANT TARGETS OF NK CELL CYTOTOXICITY. STUDIES ALSO SHOW THAT REVERSION OF TUMOR CELLS TO A LESS-DIFFERENTIATED PHENOTYPE CAN BE ACHIEVED BY BLOCKING NFKAPPAB. YOGA THERAPY (YOGIC LIFESTYLE MODIFICATIONS ENCOMPASSING PHYSICAL POSTURES, BREATHING PRACTICES, RELAXATION TECHNIQUES AND MEDITATIONS) IS KNOWN TO MODULATE NEURAL, ENDOCRINE AND IMMUNE FUNCTIONS AT THE CELLULAR LEVEL THROUGH INFLUENCING CELL CYCLE CONTROL, AGING, OXIDATIVE STRESS, APOPTOSIS AND SEVERAL PATHWAYS OF STRESS SIGNALING MOLECULES. YOGA THERAPY HAS ALSO BEEN SHOWN TO ENHANCE NATURAL KILLER CELL ACTIVITY AND MODULATE STRESS AND DNA DAMAGE IN BREAST CANCER PATIENTS RECEIVING RADIOTHERAPY. RECENT STUDY FOUND THAT BRIEF DAILY YOGIC MEDITATION MAY REVERSE THE PATTERN OF INCREASED NFKAPPAB-RELATED TRANSCRIPTION OF PRO-INFLAMMATORY CYTOKINES IN LEUKOCYTES. THUS, YOGA THERAPY HAS THE POTENTIAL TO REDUCE CANCER STEM CELL SURVIVAL, SELF -RENEWAL AND TUMOR GROWTH BY MODIFYING THE TUMOR MICRO-ENVIRONMENT THROUGH VARIOUS MECHANISMS SUCH AS; 1) REDUCING HIF-1 ACTIVITY BY ENHANCED OXYGENATION, 2) PROMOTING NK CELL ACTIVITY DIRECTLY (OR INDIRECTLY THROUGH DOWN REGULATING NFKAPPAB EXPRESSION), THEREBY ENHANCING NK CELL MEDIATED CSC LYSIS, AND 3) BY MINIMIZING THE ABERRANT EXPRESSIONS OR ACTIVITIES OF VARIOUS HORMONES, CYTOKINES, CHEMOKINES AND TUMOR SIGNALING PATHWAYS. YOGA THERAPY MAY HAVE A SYNERGISTIC EFFECT WITH CONVENTIONAL MODALITIES OF TREATMENT IN PREVENTING CANCER PROGRESSION AND RECURRENCES.	2012	

4 1112  26 EFFICACY AND TOLERABILITY OF YOGA BREATHING IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE: A PILOT STUDY. PURPOSE: YOGA-DERIVED BREATHING HAS BEEN REPORTED TO IMPROVE GAS EXCHANGE IN PATIENTS WITH CHRONIC HEART FAILURE AND IN PARTICIPANTS EXPOSED TO HIGH-ALTITUDE HYPOXIA. WE INVESTIGATED THE TOLERABILITY AND EFFECT OF YOGA BREATHING ON VENTILATORY PATTERN AND OXYGENATION IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). METHODS: PATIENTS WITH COPD (N = 11, 3 WOMEN) WITHOUT PREVIOUS YOGA PRACTICE AND TAKING ONLY SHORT-ACTING BETA2-ADRENERGIC BLOCKING DRUGS WERE ENROLLED. VENTILATORY PATTERN AND OXYGEN SATURATION WERE MONITORED BY MEANS OF INDUCTIVE PLETHYSMOGRAPHY DURING 30-MINUTE SPONTANEOUS BREATHING AT REST (SB) AND DURING A 30-MINUTE YOGA LESSON (Y). DURING THE YOGA LESSON, THE PATIENTS WERE REQUESTED TO MOBILIZE IN SEQUENCE THE DIAPHRAGM, LOWER CHEST, AND UPPER CHEST ADOPTING A SLOWER AND DEEPER BREATHING. WE EVALUATED OXYGEN SATURATION (SAO2%), TIDAL VOLUME (VT), MINUTE VENTILATION (E), RESPIRATORY RATE (I>F), INSPIRATORY TIME, TOTAL BREATH TIME, FRACTIONAL INSPIRATORY TIME, AN INDEX OF THORACOABDOMINAL COORDINATION, AND AN INDEX OF RAPID SHALLOW BREATHING. CHANGES IN DYSPNEA DURING THE YOGA LESSON WERE ASSESSED WITH THE BORG SCALE. RESULTS: DURING THE YOGA LESSON, DATA SHOWED THE ADOPTION OF A DEEPER AND SLOWER BREATHING PATTERN (VTSB L 0.54[0.04], VTY L 0.74[0.08], P = .01; I>FSB 20.8[1.3], I>FY 13.8[0.2], P = .001) AND A SIGNIFICANT IMPROVEMENT IN SAO2% WITH NO CHANGE IN E (SAO2%SB 91.5%[1.13], SAO2%Y 93.5%[0.99], P = .02; ESB L/MIN 11.2[1.1], EY L/MIN 10.2[0.9]). ALL THE PARTICIPANTS REPORTED TO BE COMFORTABLE DURING THE YOGA LESSON, WITH NO INCREASE IN DYSPNEA INDEX. CONCLUSION: WE CONCLUDE THAT SHORT-TERM TRAINING IN YOGA IS WELL TOLERATED AND INDUCES FAVORABLE RESPIRATORY CHANGES IN PATIENTS WITH COPD.	2009	
                                                                                                                                                                                                                                                                                                                                                                                       
5 2396  20 YOGA AND CHEMOREFLEX RESPONSE TO HYPOXIA AND HYPERCAPNIA. WE TESTED WHETHER CHEMOREFLEX SENSITIVITY COULD BE AFFECTED BY THE PRACTICE OF YOGA, AND WHETHER THIS IS SPECIFICALLY BECAUSE OF A SLOW BREATHING RATE OBTAINED DURING YOGA OR AS A GENERAL CONSEQUENCE OF YOGA. WE FOUND THAT SLOW BREATHING RATE PER SE SUBSTANTIALLY REDUCED CHEMOREFLEX SENSITIVITY, BUT LONG-TERM YOGA PRACTICE WAS RESPONSIBLE FOR A GENERALISED REDUCTION IN CHEMOREFLEX.	2000	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
6  652  32 EASTERN APPROACHES FOR ENHANCING WOMEN'S SEXUALITY: MINDFULNESS, ACUPUNCTURE, AND YOGA (CME). INTRODUCTION: A SIGNIFICANT PROPORTION OF WOMEN REPORT UNSATISFYING SEXUAL EXPERIENCES DESPITE NO OBVIOUS DIFFICULTIES IN THE TRADITIONAL COMPONENTS OF SEXUAL RESPONSE (DESIRE, AROUSAL, AND ORGASM). SOME SUGGEST THAT NONGOAL-ORIENTED SPIRITUAL ELEMENTS TO SEXUALITY MIGHT FILL THE GAP THAT MORE CONTEMPORARY FORMS OF TREATMENT ARE NOT ADDRESSING. AIM: EASTERN TECHNIQUES INCLUDING MINDFULNESS, ACUPUNCTURE, AND YOGA, ARE EASTERN TECHNIQUES, WHICH HAVE BEEN APPLIED TO WOMEN'S SEXUALITY. HERE, WE REVIEW THE LITERATURE ON THEIR EFFICACY. METHODS: OUR SEARCH REVEALED TWO EMPIRICAL STUDIES OF MINDFULNESS, TWO OF ACUPUNCTURE, AND ONE OF YOGA IN THE TREATMENT OF SEXUAL DYSFUNCTION. MAIN OUTCOME MEASURE: LITERATURE REVIEW OF EMPIRICAL SOURCES. RESULTS: MINDFULNESS SIGNIFICANTLY IMPROVES SEVERAL ASPECTS OF SEXUAL RESPONSE AND REDUCES SEXUAL DISTRESS IN WOMEN WITH SEXUAL DESIRE AND AROUSAL DISORDERS. IN WOMEN WITH PROVOKED VESTIBULODYNIA, ACUPUNCTURE SIGNIFICANTLY REDUCES PAIN AND IMPROVES QUALITY OF LIFE. THERE IS ALSO A CASE SERIES OF ACUPUNCTURE SIGNIFICANTLY IMPROVING DESIRE AMONG WOMEN WITH HYPOACTIVE SEXUAL DESIRE DISORDER. ALTHOUGH YOGA HAS ONLY BEEN EMPIRICALLY EXAMINED AND FOUND TO BE EFFECTIVE FOR TREATING SEXUAL DYSFUNCTION (PREMATURE EJACULATION) IN MEN, NUMEROUS HISTORICAL BOOKS CITE BENEFITS OF YOGA FOR WOMEN'S SEXUALITY. CONCLUSIONS: THE EMPIRICAL LITERATURE SUPPORTING EASTERN TECHNIQUES, SUCH AS MINDFULNESS, ACUPUNCTURE, AND YOGA, FOR WOMEN'S SEXUAL COMPLAINTS AND LOSS OF SATISFACTION IS SPARSE BUT PROMISING. FUTURE RESEARCH SHOULD AIM TO EMPIRICALLY SUPPORT EASTERN TECHNIQUES IN WOMEN'S SEXUALITY.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
7  438  25 CARDIOVASCULAR AND RESPIRATORY EFFECT OF YOGIC SLOW BREATHING IN THE YOGA BEGINNER: WHAT IS THE BEST APPROACH? SLOW BREATHING INCREASES CARDIAC-VAGAL BAROREFLEX SENSITIVITY (BRS), IMPROVES OXYGEN SATURATION, LOWERS BLOOD PRESSURE, AND REDUCES ANXIETY. WITHIN THE YOGA TRADITION SLOW BREATHING IS OFTEN PAIRED WITH A CONTRACTION OF THE GLOTTIS MUSCLES. THIS RESISTANCE BREATH "UJJAYI" IS PERFORMED AT VARIOUS RATES AND RATIOS OF INSPIRATION/EXPIRATION. TO TEST WHETHER UJJAYI HAD ADDITIONAL POSITIVE EFFECTS TO SLOW BREATHING, WE COMPARED BRS AND VENTILATORY CONTROL UNDER DIFFERENT BREATHING PATTERNS (EQUAL/UNEQUAL INSPIRATION/EXPIRATION AT 6 BREATH/MIN, WITH/WITHOUT UJJAYI), IN 17 YOGA-NAIVE YOUNG HEALTHY PARTICIPANTS. BRS INCREASED WITH SLOW BREATHING TECHNIQUES WITH OR WITHOUT EXPIRATORY UJJAYI (P < 0.05 OR HIGHER) EXCEPT WITH INSPIRATORY + EXPIRATORY UJJAYI. THE MAXIMAL INCREASE IN BRS AND DECREASE IN BLOOD PRESSURE WERE FOUND IN SLOW BREATHING WITH EQUAL INSPIRATION AND EXPIRATION. THIS CORRESPONDED WITH A SIGNIFICANT IMPROVEMENT IN OXYGEN SATURATION WITHOUT INCREASE IN HEART RATE AND VENTILATION. UJJAYI SHOWED SIMILAR INCREASE IN OXYGEN SATURATION BUT SLIGHTLY LESSER IMPROVEMENT IN BAROREFLEX SENSITIVITY WITH NO CHANGE IN BLOOD PRESSURE. THE SLOW BREATHING WITH EQUAL INSPIRATION AND EXPIRATION SEEMS THE BEST TECHNIQUE FOR IMPROVING BAROREFLEX SENSITIVITY IN YOGA-NAIVE SUBJECTS. THE EFFECTS OF UJJAYI SEEMS DEPENDENT ON INCREASED INTRATHORACIC PRESSURE THAT REQUIRES GREATER EFFORT THAN NORMAL SLOW BREATHING.	2013

THE RESULTS SUGGEST THAT LOWER CHEMOSENSITIVITY TO HYPERCAPNIA IN YOGA PRACTITIONERS MAY BE DUE TO AN ADAPTATION TO LOW ARTERIAL PH AND HIGH PACO2 FOR LONG PERIODS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
9 2224  35 THE IMPACT OF THE "YOGIC LIFESTYLE" ON CANCER PROGNOSIS AND SURVIVAL: CAN WE TARGET CANCER STEM CELLS WITH YOGA? CANCER HAS RECENTLY BEEN KNOWN TO ORIGINATE FROM STEM CELL-LIKE CELLS, CALLED CANCER STEM CELLS (CSCS). THEIR UNIQUE PROPERTIES OF SELF-DUPLICATION, MULTIPLICATION, AS WELL AS MIGRATION GIVE THE CSC RESISTANCE OVER CONVENTIONAL CANCER THERAPIES. NEWER THERAPIES ARE IN DEVELOPMENTAL STAGE TO TARGET THESE STEM CELL-LIKE POPULATIONS AND BECOME THE VANGUARD OF FUTURE TREATMENTS. SEVERAL COMPLEMENTARY AND ALTERNATIVE TREATMENTS HAVE BEEN USED IN CANCER MANAGEMENT AS AN ADJUNCT TO CONVENTIONAL THERAPY TO IMPROVE THE OVERALL QUALITY OF LIFE AND REDUCE RECURRENCE. YOGA STANDS AS THE THIRD MOST POPULAR OF ALL COMPLEMENTARY AND ALTERNATIVE MEDICINE TREATMENTS CURRENTLY USED IN CANCER PATIENTS TODAY. PRELIMINARY RESULTS SHOW THAT YOGA MODULATES NEURAL, HORMONAL, AND IMMUNE FUNCTIONS AT A CELLULAR LEVEL. THE SCOPE OF THIS COMMENTARY IS TO DISCUSS THE CURRENT EVIDENCE-BASED MEDICINE ON YOGA AND ITS EFFECT ON CSCS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10 1639  41 MODULATION OF IMMUNE RESPONSES IN STRESS BY YOGA. STRESS IS A CONSTANT FACTOR IN TODAY'S FASTPACED LIFE THAT CAN JEOPARDIZE OUR HEALTH IF LEFT UNCHECKED. IT IS ONLY IN THE LAST HALF CENTURY THAT THE ROLE OF STRESS IN EVERY AILMENT FROM THE COMMON COLD TO AIDS HAS BEEN EMPHASIZED, AND THE MECHANISMS INVOLVED IN THIS PROCESS HAVE BEEN STUDIED. STRESS INFLUENCES THE IMMUNE RESPONSE PRESUMABLY THROUGH THE ACTIVATION OF THE HYPOTHALAMIC-PITUITARY ADRENAL AXIS, HYPOTHALAMIC PITUITARY-GONADAL AXIS, AND THE SYMPATHETIC-ADRENAL-MEDULLARY SYSTEM. VARIOUS NEUROTRANSMITTERS, NEUROPEPTIDES, HORMONES, AND CYTOKINES MEDIATE THESE COMPLEX BIDIRECTIONAL INTERACTIONS BETWEEN THE CENTRAL NERVOUS SYSTEM (CNS) AND THE IMMUNE SYSTEM. THE EFFECTS OF STRESS ON THE IMMUNE RESPONSES RESULT IN ALTERATIONS IN THE NUMBER OF IMMUNE CELLS AND CYTOKINE DYSREGULATION. VARIOUS STRESS MANAGEMENT STRATEGIES SUCH AS MEDITATION, YOGA, HYPNOSIS, AND MUSCLE RELAXATION HAVE BEEN SHOWN TO REDUCE THE PSYCHOLOGICAL AND PHYSIOLOGICAL EFFECTS OF STRESS IN CANCERS AND HIV INFECTION. THIS REVIEW AIMS TO DISCUSS THE EFFECT OF STRESS ON THE IMMUNE SYSTEM AND EXAMINE HOW RELAXATION TECHNIQUES SUCH AS YOGA AND MEDITATION COULD REGULATE THE CYTOKINE LEVELS AND HENCE, THE IMMUNE RESPONSES DURING STRESS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
11 1669  41 NEUROPHYSIOLOGICAL AND NEUROCOGNITIVE MECHANISMS UNDERLYING THE EFFECTS OF YOGA-BASED PRACTICES: TOWARDS A COMPREHENSIVE THEORETICAL FRAMEWORK. DURING RECENT DECADES NUMEROUS YOGA-BASED PRACTICES (YBP) HAVE EMERGED IN THE WEST, WITH THEIR AIMS RANGING FROM FITNESS GAINS TO THERAPEUTIC BENEFITS AND SPIRITUAL DEVELOPMENT. YOGA IS ALSO BEGINNING TO SPARK GROWING INTEREST WITHIN THE SCIENTIFIC COMMUNITY, AND YOGA-BASED INTERVENTIONS HAVE BEEN ASSOCIATED WITH MEASUREABLE CHANGES IN PHYSIOLOGICAL PARAMETERS, PERCEIVED EMOTIONAL STATES, AND COGNITIVE FUNCTIONING. YBP TYPICALLY INVOLVE A COMBINATION OF POSTURES OR MOVEMENT SEQUENCES, CONSCIOUS REGULATION OF THE BREATH, AND VARIOUS TECHNIQUES TO IMPROVE ATTENTIONAL FOCUS. HOWEVER, SO FAR LITTLE IF ANY RESEARCH HAS ATTEMPTED TO DECONSTRUCT THE ROLE OF THESE DIFFERENT COMPONENT PARTS IN ORDER TO BETTER UNDERSTAND THEIR RESPECTIVE CONTRIBUTION TO THE EFFECTS OF YBP. A CLEAR OPERATIONAL DEFINITION OF YOGA-BASED THERAPEUTIC INTERVENTIONS FOR SCIENTIFIC PURPOSES, AS WELL AS A COMPREHENSIVE THEORETICAL FRAMEWORK FROM WHICH TESTABLE HYPOTHESES CAN BE FORMULATED, IS THEREFORE NEEDED. HERE WE PROPOSE SUCH A FRAMEWORK, AND OUTLINE THE BOTTOM-UP NEUROPHYSIOLOGICAL AND TOP-DOWN NEUROCOGNITIVE MECHANISMS HYPOTHESIZED TO BE AT PLAY IN YBP.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
12  741  22 EFFECT OF REGULAR YOGA PRACTICE ON RESPIRATORY REGULATION AND EXERCISE PERFORMANCE. YOGA ALTERS SPONTANEOUS RESPIRATORY REGULATION AND REDUCES HYPOXIC AND HYPERCAPNIC VENTILATORY RESPONSES. SINCE A LOWER VENTILATORY RESPONSE IS ASSOCIATED WITH AN IMPROVED ENDURANCE CAPACITY DURING WHOLE-BODY EXERCISE, WE TESTED WHETHER YOGIC SUBJECTS (YOGA) SHOW AN INCREASED ENDURANCE CAPACITY COMPARED TO MATCHED NON-YOGIC INDIVIDUALS (CON) WITH SIMILAR PHYSICAL ACTIVITY LEVELS. RESTING VENTILATION, THE VENTILATORY RESPONSE TO HYPERCAPNIA, PASSIVE LEG MOVEMENT AND EXERCISE, AS WELL AS ENDURANCE PERFORMANCE WERE ASSESSED. YOGA (N = 9), COMPARED TO CONTROL (N = 6), HAD A HIGHER TIDAL VOLUME AT REST (0.7+/-0.2 VS. 0.5+/-0.1 L, P = 0.034) AND A REDUCED VENTILATORY RESPONSE TO HYPERCAPNIA (33+/-15 VS. 47+/-15 L.MIN(-1), P = 0.048). A YOGA SUBGROUP (N = 6) WITH MAXIMAL PERFORMANCE SIMILAR TO CONTROL SHOWED A BLUNTED VENTILATORY RESPONSE TO PASSIVE CYCLING (11+/-2 VS. 14+/-2 L.MIN(-1), P = 0.039) AND A TENDENCY TOWARDS LOWER EXERCISE VENTILATION (33+/-2 VS. 36+/-3 L.MIN(-1), P = 0.094) WHILE CYCLING ENDURANCE (YOGA: 17.3+/-3.3; CON: 19.6+/-8.5 MIN, P = 0.276) DID NOT DIFFER. THUS, YOGA PRACTICE WAS NOT ASSOCIATED WITH IMPROVED EXERCISE CAPACITY NOR WITH SIGNIFICANT CHANGES IN EXERCISE VENTILATION DESPITE A SIGNIFICANTLY DIFFERENT RESPIRATORY REGULATION AT REST AND IN RESPONSE TO HYPERCAPNIA AND PASSIVE LEG MOVEMENT.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
13 1773  45 POTENTIAL YOGA MODULES FOR TREATMENT OF HEMATOPOIETIC INHIBITION IN HIV-1 INFECTION. THIS ARTICLE IS EXPECTED TO CONTRIBUTE TOWARDS UNDERSTANDING THE THERAPEUTIC BENEFITS OF SPECIFIC YOGA MODULES ON THE INHIBITION OF REPLICATION AND ENHANCEMENT TO NORMAL LEVELS OF HEMATOPOIESIS IN HIV-1 INFECTED SUBJECTS. MORE UNIQUE COULD BE THE EFFECTS OF YOGA ON THE INDIRECT EFFECTS OF HIV-1 INDUCED HEMATOPOIETIC INHIBITION OF THE CD34+ PROGENITOR STEM CELLS, VIA THE CD4+ T LYMPHOCYTES. SUCH INDIRECT EFFECTS MAY BE CAUSED BY HOST CELLULAR FACTORS. YOGA PRACTICES MAY ALSO IMPROVE THE SELF RENEWAL CAPACITY (A STEP THAT PRECEDES COMMITMENT OF CD34+ PROGENITOR CELLS TO TERMINAL DIFFERENTIATION), VIA STAT5 GENE REGULATION. THIS MAY ELIMINATE THE NEED FOR CONSTITUTIVE STAT5 GENE EXPRESSION THROUGH GENE THERAPY. IN THIS ARTICLE RECENT RESEARCH AND ANCIENT INDIAN LITERATURE ARE REVIEWED TO DEVISE YOGA MODULES FOR THE POTENTIAL TREATMENT OF HEMATOPOIETIC INHIBITION IN HIV-1 INFECTION. THE POSSIBLE MECHANISMS THROUGH WHICH HEMATOPOIETIC INHIBITION MAY OCCUR IN HIV-1 INFECTED PATIENTS ARE FIRST DESCRIBED FOLLOWED BY THE ROLE OF STRESS IN THE PROGRESSION OF HIV WHERE PROBABLE INVOLVEMENT OF PSYCHO-NEURO-IMMUNOLOGICAL AXIS (PNI) IS HIGHLIGHTED. YOGA THERAPY IS INTRODUCED AND ITS EFFECTIVENESS IN TERMS OF EVIDENCE IN RELEVANT AREA IS REVIEWED. FURTHER, THE BASIC PRINCIPLES OF INTEGRATED APPROACH OF YOGA THERAPY [IAYT] ARE DESCRIBED AND DEPENDING ON THE POTENTIAL MECHANISMS THROUGH WHICH YOGA THERAPY MAY ACT, BOTH MODERN SCIENTIFIC RESEARCH AND ANCIENT "SCRIPTURAL" EVIDENCE ARE PROVIDED AT ALL THE FIVE LEVELS OF EXISTENCE (BODY, LIFE FORCE, EMOTIONAL, INTELLECTUAL AND BLISS). THIS WILL ENABLE TO DESIGN COMPREHENSIVE YOGA MODULES THAT MAY INTERVENE IN THIS INDIRECT INHIBITION OF HAEMATOPOIESIS IN HIV-1 INFECTED INDIVIDUALS AND POTENTIALLY RESTORE NORMAL LEVELS OF HAEMATOPOIESIS.	2010	
                                                                                                                                                                                                                                                                                                                                                                        
14  571  22 DEFINING YOGA-NIDRA: TRADITIONAL ACCOUNTS, PHYSIOLOGICAL RESEARCH, AND FUTURE DIRECTIONS. THE TERM YOGA-NIDRA HAS BEEN USED IN MANY EMPIRICAL STUDIES TO REFER TO RELAXATION AND GUIDED IMAGERY. THESE TECHNIQUES DO NOT REPRESENT THE INTENTION OR PHYSIOLOGICAL CORRELATES OF YOGANIDRA DISCUSSED IN THE TRADITIONAL YOGA LITERATURE. WE PROPOSE AN OPERATIONAL DEFINITION OF YOGA-NIDRA THAT IS SUPPORTED BY SEVERAL PHYSIOLOGICALLY TESTABLE HYPOTHESES REGARDING ITS OUTCOMES AND EFFECTS. TRADITIONAL DESCRIPTIONS OF YOGA-NIDRA AND CONTEMPORARY ACCOUNTS OF ITS PRACTICE ARE REVIEWED, AND STUDIES EXAMINING THE PHYSIOLOGICAL CORRELATES OF YOGA-NIDRA ARE EXAMINED. PROPOSED HYPOTHESES FOR FUTURE RESEARCH USING THIS OPERATIONAL DEFINITION ARE PROVIDED.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
15   82  48 A MECHANISTIC MODEL FOR YOGA AS A PREVENTIVE AND THERAPEUTIC MODALITY. YOGA IS AN ANCIENT INDIAN TECHNIQUE OF HEALTHY LIVING. NUMEROUS STUDIES HAVE CORROBORATED YOGA'S BENEFICIAL EFFECTS, INCLUDING A FAVORABLE INFLUENCE ON AUTONOMIC FUNCTION AND NEGATIVE EMOTIONS. EXTENSIVE RESEARCH IN THE LAST FEW DECADES HAS REVEALED THE CRITICAL ROLE THAT YOGA CAN PLAY IN ERADICATING STRESS. THIS HAS LAID TO THE FOUNDATION FOR A SCIENTIFIC UNDERSTANDING OF PATHOPHYSIOLOGICAL CHANGES ATTRIBUTED TO STRESS, PARTICULARLY AT THE MOLECULAR AND GENETIC LEVELS. THIS PRIMARILY HAS HELPED UNDERSTAND THE EPIGENETIC AND GENETIC MECHANISM AT PLAY TO INDUCE AND ALLEVIATE STRESS, PARTICULARLY THOSE RELATED TO EMOTIONAL ABERRATIONS. AS RESEARCH HAS INDICATED, NEGATIVE EMOTIONS ARE TRANSLATED INTO VASCULAR INFLAMMATION APPROPRIATELY ACCENTUATED BY A SYMPATHETIC PREDOMINANT AUTONOMIC FUNCTION. THIS CASCADE IS BOLSTERED BY MULTIPLE FACTORS, INCLUDING ACTIVATION OF "STRESSOR" GENES AND ELABORATING HORMONES, INCLUDING STEROIDS WITH SOMETIMES NOCUOUS CONSEQUENCES, PARTICULARLY WHEN CHRONIC. YOGA HAS BEEN CATEGORICALLY FOUND TO HAVE INHIBITED EACH AND EVERY ONE OF THESE BANEFUL EFFECTS OF STRESS. IN FACT, IT ALSO CHANGES THE NEURONAL CIRCUITS THAT POTENTIATE SUCH A PLETHORA OF PATHOLOGICAL CHANGES. THIS, IN TURN, HAS ACCENTUATED YOGA'S RELEVANCE AS A POWERFUL PREVENTIVE INTERVENTION IN NONCOMMUNICABLE DISEASES (NCD). NCDS, INCLUDING HEART DISEASE, STROKE, AND RHEUMATOLOGICAL DISORDERS, ARE ESSENTIALLY INFLAMMATORY DISEASES THAT PERPETUATE INFLAMMATION IN DIFFERENT BEDS LIKE VASCULAR OR JOINT SPACES. THE PRECISE MECHANISM BY WHICH YOGA INDUCES SUCH BENEFICIAL CHANGES IS YET TO BE DELINEATED. HOWEVER, A CORNUCOPIA OF POINTERS INDICATES THAT NEURAL, ENDOCRINE, IMMUNOLOGICAL, CELLULAR, GENETIC, AND EPIGENETIC MECHANISMS ARE AT PLAY. THIS ARTICLE ATTEMPTS TO COBBLE TOGETHER NEWFANGLED RESEARCH TO DELINEATE A MEDICAL MODEL FOR THIS 5000-YEAR-OLD PRACTICE FROM INDIA. THIS IS IMPERATIVE, AS A MECHANISTIC MODEL OF THIS ANCIENT-BUT-COMPLEX SYSTEM WOULD ENABLE A MORE COMPREHENSIVE UNDERSTANDING OF ITS MECHANISM AND REVEAL ITS YET-UNDISCOVERED POSITIVE HEALTH EFFECTS.	2021	
                                                                                    
16 2886  38 YOGA: BALANCING THE EXCITATION-INHIBITION EQUILIBRIUM IN PSYCHIATRIC DISORDERS. SOCIAL BEHAVIORAL DISTURBANCES ARE CENTRAL TO MOST PSYCHIATRIC DISORDERS. A DISEQUILIBRIUM WITHIN THE CORTICAL EXCITATORY AND INHIBITORY NEUROTRANSMITTER SYSTEMS UNDERLIES THESE DEFICITS. GAMMA-AMINOBUTYRIC ACID (GABA) AND GLUTAMATE ARE THE MOST ABUNDANT EXCITATORY AND INHIBITORY NEUROTRANSMITTERS IN THE BRAIN THAT CONTRIBUTE TO THIS EQUILIBRIUM. SEVERAL CONTEMPORARY THERAPIES USED IN TREATING PSYCHIATRIC DISORDERS, REGULATE THIS GABA-GLUTAMATE BALANCE. YOGA HAS BEEN STUDIED AS AN ADJUVANT TREATMENT ACROSS A BROAD RANGE OF PSYCHIATRIC DISORDERS AND IS SHOWN TO HAVE SHORT-TERM THERAPEUTIC GAINS. EMERGING EVIDENCE FROM RECENT CLINICAL IN VIVO EXPERIMENTS SUGGESTS THAT YOGA IMPROVES GABA-MEDIATED CORTICAL-INHIBITORY TONE AND ENHANCES PERIPHERAL OXYTOCIN LEVELS. THIS IS LIKELY TO HAVE A MORE CONTROLLED DOWNSTREAM RESPONSE OF THE HYPOTHALAMO-PITUITARY-ADRENAL SYSTEM BY MEANS OF REDUCED CORTISOL RELEASE AND HENCE A BLUNTED SYMPATHETIC RESPONSE TO STRESS. ANIMAL AND EARLY FETAL DEVELOPMENTAL STUDIES SUGGEST AN INTER-DEPENDENT ROLE OF OXYTOCIN AND GABA IN REGULATING SOCIAL BEHAVIORS. IN KEEPING WITH THESE OBSERVATIONS, WE PROPOSE AN INTEGRATED NEUROBIOLOGICAL MODEL TO STUDY THE MECHANISMS OF THERAPEUTIC BENEFITS WITH YOGA. APART FROM PROVIDING A NEUROSCIENTIFIC BASIS FOR APPLYING A TRADITIONAL SYSTEM OF PRACTICE IN THE CLINICAL SETTING, THIS MODEL CAN BE USED AS A FRAMEWORK FOR STUDYING YOGA MECHANISMS IN FUTURE CLINICAL TRIALS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
17 1634  40 MODELING THE EFFECTS OF YOGA ON THE PROGRESSION OF ALZHEIMER'S DISEASE IN A DISH. ALZHEIMER'S DISEASE (AD) ACCOUNTS FOR 80% OF ALL DEMENTIA CASES, MAKING IT THE MOST COMMON FORM OF DEMENTIA. AGING SERVES AS THE MAIN RISK FACTOR FOR AD, BUT EARLY ONSET AD CAN ALSO OCCUR IN INDIVIDUALS YOUNGER THAN 65 YEARS. AD RESULTS FROM PROGRESSIVE NEURODEGENERATION LEADING TO DYSFUNCTIONAL SYNAPTIC TRANSMISSION IN THE BRAIN. THE CASCADE HYPOTHESIS OF AD STATES THAT AMYLOID PRECURSOR PROTEIN (APP) METABOLISM BECOMES IMPAIRED EITHER BY MUTATION OR AN INTERLEUKIN-MEDIATED STRESS RESPONSE TO INJURY, RESULTING IN THE SPLICING OF HARMFUL OLIGOMERIC FORMS OF AMYLOID BETA (ABETA). THESE OLIGOMERS DISRUPT EXTRACELLULAR RECEPTOR BINDING, INTRACELLULAR FUNCTION, AND CELLULAR MEMBRANE INTEGRITY. YOGA AND MEDITATIVE PRACTICES SLOW THE PROGRESSION OF THE COGNITIVE DECLINE ASSOCIATED WITH AD. HOWEVER, THE BIOLOGICAL MECHANISMS UNDERLYING THIS THERAPEUTIC EFFECT REMAIN ELUSIVE. HERE, WE INVESTIGATED THE ABILITY OF NEUROTRANSMITTERS RELEASED DURING YOGA AND MEDITATIVE PRACTICES TO RESCUE NEURONS FROM SYNAPTIC DYSFUNCTION IN AN IN VITRO ALZHEIMER'S MODEL CREATED BY CULTURING BASAL FOREBRAIN CHOLINERGIC NEURONS WITH PHYSIOLOGICALLY RELEVANT LEVELS OF THE I-42 ISOFORM OF OLIGOMERIC ABETA (OALPHABETAI-42). WE FOUND THAT THE NEUROTRANSMITTERS DOPAMINE AND HISTAMINE PRODUCE A COOPERATIVE ACTION WITH SEROTONIN TO REVERSE THE LOSS OF CHOLINE ACETYLTRANSFERASE (CHAT) BY OALPHABETAI-42. THE LOSS OF CHAT, THE ENZYME RESPONSIBLE FOR PROCESSING THE CHOLINERGIC NEUROTRANSMITTER ACETYLCHOLINE, CONTRIBUTES TO THE SYNAPTIC DYSFUNCTION EXPERIENCED DURING AD. THESE NEUROTRANSMITTERS INHIBIT NITRIC OXIDE SYNTHESIS CAUSED BY OALPHABETAI-42, PREVENTING OXIDATIVE AND NITROSATIVE STRESS. SEROTONIN ACTIVATES AN ALTERNATE CLEAVAGE OF APP TO PRODUCE A FRAGMENT WITH KNOWN NEUROTROPHIC EFFECTS, GIVING IT THE UNIQUE ABILITY TO INHIBIT THE OALPHABETAI-42 PRODUCTION CYCLE. WE HYPOTHESIZE HERE THAT THESE CONCERTED ACTIONS LEAD TO THE PROTECTION OF CHOLINERGIC SYNAPTIC TRANSMISSION IN AD.	2018	
                                                                                                                                                                                     
18 1266  21 FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ORGANIZATION IN AGING YOGA AND MEDITATION PRACTITIONERS. NUMEROUS STUDIES HAVE DOCUMENTED THE NORMAL AGE-RELATED DECLINE OF NEURAL STRUCTURE, FUNCTION, AND COGNITIVE PERFORMANCE. PRELIMINARY EVIDENCE SUGGESTS THAT MEDITATION MAY REDUCE DECLINE IN SPECIFIC COGNITIVE DOMAINS AND IN BRAIN STRUCTURE. HERE WE EXTENDED THIS RESEARCH BY INVESTIGATING THE RELATION BETWEEN AGE AND FLUID INTELLIGENCE AND RESTING STATE BRAIN FUNCTIONAL NETWORK ARCHITECTURE USING GRAPH THEORY, IN MIDDLE-AGED YOGA AND MEDITATION PRACTITIONERS, AND MATCHED CONTROLS. FLUID INTELLIGENCE DECLINED SLOWER IN YOGA PRACTITIONERS AND MEDITATORS COMBINED THAN IN CONTROLS. RESTING STATE FUNCTIONAL NETWORKS OF YOGA PRACTITIONERS AND MEDITATORS COMBINED WERE MORE INTEGRATED AND MORE RESILIENT TO DAMAGE THAN THOSE OF CONTROLS. FURTHERMORE, MINDFULNESS WAS POSITIVELY CORRELATED WITH FLUID INTELLIGENCE, RESILIENCE, AND GLOBAL NETWORK EFFICIENCY. THESE FINDINGS REVEAL THE POSSIBILITY TO INCREASE RESILIENCE AND TO SLOW THE DECLINE OF FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ARCHITECTURE AND SUGGEST THAT MINDFULNESS PLAYS A MECHANISTIC ROLE IN THIS PRESERVATION.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19  321  40 ANALOGY BETWEEN CLASSICAL YOGA/ZEN BREATHING AND MODERN CLINICAL RESPIRATORY THERAPY. ANESTHESIOLOGISTS AND INTENSIVISTS ARE MODERN-DAY PROFESSIONALS WHO PROVIDE APPROPRIATE RESPIRATORY CARE, VITAL FOR PATIENT SURVIVAL. RECENTLY, ANESTHESIOLOGISTS HAVE INCREASINGLY FOCUSED THEIR ATTENTION ON THE TYPE OF SPONTANEOUS BREATHING MADE BY NON-INTUBATED PATIENTS WITH PULMONARY DISEASE CARED FOR IN AN INTENSIVE CARE UNIT, AND ALSO PATIENTS WITH CHRONIC PAIN RECEIVING COGNITIVE BEHAVIORAL THERAPY. PRIOR TO OUR MODERN UNDERSTANDING OF RESPIRATORY PHYSIOLOGY, ZEN MEDITATORS RECOGNIZED THAT BREATHING HAS A SIGNIFICANT IMPACT ON A PERSON'S MENTAL STATE AND GENERAL PHYSICAL WELL-BEING. EXAMPLES OF THIS KNOWLEDGE REGARDING RESPIRATION INCLUDE THE BENEFICIAL EFFECTS OF DEEP INHALATION AND SLOW EXHALATION ON ANXIETY AND GENERAL WELLNESS. THE CLASSICAL LITERATURE HAS NOTED MANY SUGGESTIONS FOR BREATHING AND ITS PSYCHO-PHYSICAL EFFECTS. IN THE PRESENT REVIEW, WE EXAMINE THE EFFECT OF CLASSICAL BREATHING METHODS AND FIND AN ANALOGY BETWEEN TYPICAL YOGA/ZEN BREATHING AND MODERN CLINICAL RESPIRATORY THERAPY. EVIDENCE IS INCREASING ABOUT HISTORICAL BREATHING AND RELATED MEDITATION TECHNIQUES THAT MAY BE EFFECTIVE IN MODERN CLINICAL PRACTICE, ESPECIALLY IN THE FIELD OF ANESTHESIOLOGY, SUCH AS IN IMPROVING RESPIRATORY FUNCTION AND REDUCING CHRONIC PAIN. CLARIFICATION OF THE DETAILED MECHANISMS INVOLVED IS ANTICIPATED.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
20 1590  24 MEDITATION AND YOGA CAN MODULATE BRAIN MECHANISMS THAT AFFECT BEHAVIOR AND ANXIETY-A MODERN SCIENTIFIC PERSPECTIVE. MEDITATION AND YOGA TECHNIQUES ARE RECEIVING INCREASED ATTENTION THROUGHOUT THE WORLD, DUE TO THE ACCUMULATION OF EVIDENCE BASED RESEARCH THAT PROVES THE DIRECT AND INDIRECT BENEFITS OF SUCH PRACTICES. BASED ON STUDIES CONDUCTED SO FAR, IT HAS BEEN FOUND THAT THE PRACTICE OF MEDITATION TRIGGERS NEUROTRANSMITTERS THAT MODULATE PSYCHOLOGICAL DISORDERS SUCH AS ANXIETY. THIS PAPER WILL REVIEW THE PSYCHOLOGICAL EFFECTS OF THE PRACTICE OF MEDITATION, THE ROLE OF NEUROTRANSMITTERS, AND STUDIES USING EEG AND FMRI.	2015
