1  761 161 EFFECT OF SUDARSHAN KRIYA YOGA (SKY) ON DAYTIME AND SITUATIONAL SLEEP PROPENSITY IN NOVICE PRACTITIONERS: A PROSPECTIVE COHORT STUDY. OBJECTIVES: HECTIC, LATE-NIGHT LIFESTYLE HAS REDUCED 90 MIN SLEEP IN 20% ADULTS RESULTING IN INSOMNIA AND EXCESSIVE DAYTIME SLEEPINESS (EDS). WE ASSESS THE SCOPE OF SUDARSHAN KRIYA YOGA (SKY), A 4-COMPONENT, BREATHING PROCESS IN REDUCING EDS, GENERALLY AND SITUATIONALLY. METHODS: THIS IS A PROSPECTIVE, CONTROLLED STUDY INVOLVING RANDOMIZED SUBJECTS WITHOUT ANY SLEEP-WAKE CYCLE ANOMALIES AND PRIOR EXPERIENCE IN SKY. SUBJECTS (N=52) PERFORMED 30 MIN OF SKY FOR 6 DAYS/WEEK FOR 8 WEEKS, WHILE CONTROLS (N=53) PERFORMED SITTING ACTIVITY AND SURYANAMASKAR FOR 4-WEEKS EACH. EPWORTH SLEEPINESS SCALE (ESS) WAS USED TO MEASURE EDS AT 0, 4, AND 8 WEEKS. RESULTS: SKY GROUP SHOWED SIGNIFICANT ESS SCORE IMPROVEMENTS BETWEEN 0-4 WEEKS AND 4-8 WEEKS OF 1.22 (P=0.0001) AND 1.66 (P=0.001) RESPECTIVELY. CONTROLS HOWEVER FAILED TO IMPROVE WITH SCORE DIFFERENCES OF 0.02 (P=0.892) AND 0.02 (P=0.8212) RESPECTIVELY. SKY GROUP SHOWED SIGNIFICANT ESS SCORE IMPROVEMENT OVER CONTROLS AT 4-WEEKS (DIFFERENCE=1.74; P=0.013) AND 8-WEEKS (DIFFERENCE EIGHT; P=0.0001). IMPROVEMENT WAS MOST FOR OBESE PEOPLE AND THOSE SITTING IN A HALTED CAR. CONCLUSIONS: IMPROVEMENT IN SUBJECTS' NIGHTTIME SLEEP AND DAYTIME WAKEFULNESS IN SKY PRACTITIONERS CAN BE ATTRIBUTED TO POLYVAGAL THEORY. INCREASED HEART RATE VARIABILITY (HRV) ALTERATIONS AND SYMPATHETIC HYPERAROUSAL IN CHRONIC INSOMNIA; AND CHOLINERGIC AND GABAERGIC DYSREGULATION IN ANXIETY DISORDERS ARE COUNTERED BY REGULATED VAGAL NERVE STIMULATION POST SKY. OUR STUDY ESTABLISHES EFFECTIVITY OF SKY IN REDUCING EDS (TOTAL AND SITUATIONAL), PROVIDES A CLINICAL CORRELATION FOR PRIOR POLYSOMNOGRAPHIC EVIDENCE AND PAVES WAY FOR LARGER TRIALS DIRECTED TOWARDS SKY PRESCRIPTIONS FOR INSOMNIA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                      
2 1634  22 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	
                                                                                                                                                                      
3 1667  30 NEUROCHEMICAL AND NEUROANATOMICAL PLASTICITY FOLLOWING MEMORY TRAINING AND YOGA INTERVENTIONS IN OLDER ADULTS WITH MILD COGNITIVE IMPAIRMENT. BEHAVIORAL INTERVENTIONS ARE BECOMING INCREASINGLY POPULAR APPROACHES TO AMELIORATE AGE-RELATED COGNITIVE DECLINE, BUT THEIR UNDERLYING NEUROBIOLOGICAL MECHANISMS AND CLINICAL EFFICIENCY HAVE NOT BEEN FULLY ELUCIDATED. THE PRESENT STUDY EXPLORED BRAIN PLASTICITY ASSOCIATED WITH TWO BEHAVIORAL INTERVENTIONS, MEMORY ENHANCEMENT TRAINING (MET) AND A MIND-BODY PRACTICE (YOGIC MEDITATION), IN HEALTHY SENIORS WITH MILD COGNITIVE IMPAIRMENT (MCI) USING STRUCTURAL MAGNETIC RESONANCE IMAGING (S-MRI) AND PROTON MAGNETIC RESONANCE SPECTROSCOPY ((1)H-MRS). SENIOR PARTICIPANTS (AGE >/=55 YEARS) WITH MCI WERE RANDOMIZED TO THE MET OR YOGIC MEDITATION INTERVENTIONS. FOR BOTH INTERVENTIONS, PARTICIPANTS COMPLETED EITHER MET TRAINING OR KUNDALINI YOGA (KY) FOR 60-MIN SESSIONS OVER 12 WEEKS, WITH 12-MIN DAILY HOMEWORK ASSIGNMENTS. GRAY MATTER VOLUME AND METABOLITE CONCENTRATIONS IN THE DORSAL ANTERIOR CINGULATE CORTEX (DACC) AND BILATERAL HIPPOCAMPUS WERE MEASURED BY STRUCTURAL MRI AND (1)H-MRS AT BASELINE AND AFTER 12 WEEKS OF TRAINING. METABOLITES MEASURED INCLUDED GLUTAMATE-GLUTAMINE (GLX), CHOLINE-CONTAINING COMPOUNDS (CHO, INCLUDING GLYCEROPHOSPHOCHOLINE AND PHOSPHOCHOLINE), GAMMA-AMINOBUTYRIC ACID (GABA), AND N-ACETYL ASPARTATE AND N-ACETYLASPARTYL-GLUTAMATE (NAA-NAAG). IN TOTAL, 11 PARTICIPANTS COMPLETED MET AND 14 COMPLETED YOGIC MEDITATION FOR THIS STUDY. STRUCTURAL MRI ANALYSIS SHOWED AN INTERACTION BETWEEN TIME AND GROUP IN DACC, INDICATING A TREND TOWARDS INCREASED GRAY MATTER VOLUME AFTER THE MET INTERVENTION. (1)H-MRS ANALYSIS SHOWED AN INTERACTION BETWEEN TIME AND GROUP IN CHOLINE-CONTAINING COMPOUNDS IN BILATERAL HIPPOCAMPUS, INDUCED BY SIGNIFICANT DECREASES AFTER THE MET INTERVENTION. THOUGH PRELIMINARY, OUR RESULTS SUGGEST THAT MEMORY TRAINING INDUCES STRUCTURAL AND NEUROCHEMICAL PLASTICITY IN SENIORS WITH MCI. FURTHER RESEARCH IS NEEDED TO DETERMINE WHETHER MIND-BODY INTERVENTIONS LIKE YOGA YIELD SIMILAR NEUROPLASTIC CHANGES.	2016	
                                                                                                                            
4 2295  27 THERAPEUTIC POTENTIAL OF YOGA PRACTICES IN MODIFYING CARDIOVASCULAR RISK PROFILE IN MIDDLE AGED MEN AND WOMEN. AIMS OF STUDY: TO STUDY EFFECT OF YOGA ON THE PHYSIOLOGICAL, PSYCHOLOGICAL WELL BEING, PSYCHOMOTOR PARAMETER AND MODIFYING CARDIOVASCULAR RISK FACTORS IN MILD TO MODERATE HYPERTENSIVE PATIENTS. METHODS: TWENTY PATIENTS (16 MALES, 4 FEMALES) IN THE AGE GROUP OF 35 TO 55 YEARS WITH MILD TO MODERATE ESSENTIAL HYPERTENSION UNDERWENT YOGIC PRACTICES DAILY FOR ONE HOUR FOR THREE MONTHS. BIOCHEMICAL, PHYSIOLOGICAL AND PSYCHOLOGICAL PARAMETERS WERE STUDIED PRIOR AND FOLLOWING PERIOD OF THREE MONTHS OF YOGA PRACTICES, BIOCHEMICAL PARAMETERS INCLUDED, BLOOD GLUCOSE, LIPID PROFILE, CATECHOLMINES, MDA, VIT. C CHOLINESTERASE AND URINARY VMA. PSYCHOLOGICAL EVALUATION WAS DONE BY USING PERSONAL ORIENTATION INVENTORY AND SUBJECTIVE WELL BEING. RESULTS: RESULTS SHOWED DECREASE IN BLOOD PRESSURE AND DRUG SCORE MODIFYING RISK FACTORS, I.E. BLOOD GLUCOSE, CHOLESTEROL AND TRIGLYCERIDES DECREASED OVERALL IMPROVEMENT IN SUBJECTIVE WELL BEING AND QUALITY OF LIFE. THERE WAS DECREASE IN VMA CATECHOLAMINE, AND DECREASE MDA LEVEL SUGGESTIVE DECREASE SYMPATHETIC ACTIVITY AND OXIDANT STRESS. CONCLUSION: YOGA CAN PLAY AN IMPORTANT ROLE IN RISK MODIFICATION FOR CARDIOVASCULAR DISEASES IN MILD TO MODERATE HYPERTENSION.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
5 1089  35 EFFECTS OF YOGA ON THE AUTONOMIC NERVOUS SYSTEM, GAMMA-AMINOBUTYRIC-ACID, AND ALLOSTASIS IN EPILEPSY, DEPRESSION, AND POST-TRAUMATIC STRESS DISORDER. A THEORY IS PROPOSED TO EXPLAIN THE BENEFITS OF YOGA PRACTICES IN DIVERSE, FREQUENTLY COMORBID MEDICAL CONDITIONS BASED ON THE CONCEPT THAT YOGA PRACTICES REDUCE ALLOSTATIC LOAD IN STRESS RESPONSE SYSTEMS SUCH THAT OPTIMAL HOMEOSTASIS IS RESTORED. IT IS HYPOTHESIZED THAT STRESS INDUCES (1) IMBALANCE OF THE AUTONOMIC NERVOUS SYSTEM (ANS) WITH DECREASED PARASYMPATHETIC NERVOUS SYSTEM (PNS) AND INCREASED SYMPATHETIC NERVOUS SYSTEM (SNS) ACTIVITY, (2) UNDERACTIVITY OF THE GAMMA AMINO-BUTYRIC ACID (GABA) SYSTEM, THE PRIMARY INHIBITORY NEUROTRANSMITTER SYSTEM, AND (3) INCREASED ALLOSTATIC LOAD. IT IS FURTHER HYPOTHESIZED THAT YOGA-BASED PRACTICES (4) CORRECT UNDERACTIVITY OF THE PNS AND GABA SYSTEMS IN PART THROUGH STIMULATION OF THE VAGUS NERVES, THE MAIN PERIPHERAL PATHWAY OF THE PNS, AND (5) REDUCE ALLOSTATIC LOAD. DEPRESSION, EPILEPSY, POST TRAUMATIC STRESS DISORDER (PTSD), AND CHRONIC PAIN EXEMPLIFY MEDICAL CONDITIONS THAT ARE EXACERBATED BY STRESS, HAVE LOW HEART RATE VARIABILITY (HRV) AND LOW GABAERGIC ACTIVITY, RESPOND TO PHARMACOLOGIC AGENTS THAT INCREASE ACTIVITY OF THE GABA SYSTEM, AND SHOW SYMPTOM IMPROVEMENT IN RESPONSE TO YOGA-BASED INTERVENTIONS. THE OBSERVATION THAT TREATMENT RESISTANT CASES OF EPILEPSY AND DEPRESSION RESPOND TO VAGAL NERVE STIMULATION CORROBORATES THE NEED TO CORRECT PNS UNDERACTIVITY AS PART OF A SUCCESSFUL TREATMENT PLAN IN SOME CASES. ACCORDING TO THE PROPOSED THEORY, THE DECREASED PNS AND GABAERGIC ACTIVITY THAT UNDERLIES STRESS-RELATED DISORDERS CAN BE CORRECTED BY YOGA PRACTICES RESULTING IN AMELIORATION OF DISEASE SYMPTOMS. THIS HAS FAR-REACHING IMPLICATIONS FOR THE INTEGRATION OF YOGA-BASED PRACTICES IN THE TREATMENT OF A BROAD ARRAY OF DISORDERS EXACERBATED BY STRESS.	2012	
                                                                                                                                                                                                                                                                                                                                                       
6 1472  24 INSULAR CORTEX MEDIATES INCREASED PAIN TOLERANCE IN YOGA PRACTITIONERS. YOGA, AN INCREASINGLY POPULAR DISCIPLINE AMONG WESTERNERS, IS FREQUENTLY USED TO IMPROVE PAINFUL CONDITIONS. WE INVESTIGATED POSSIBLE NEUROANATOMICAL UNDERPINNINGS OF THE BENEFICIAL EFFECTS OF YOGA USING SENSORY TESTING AND MAGNETIC RESONANCE IMAGING TECHNIQUES. NORTH AMERICAN YOGIS TOLERATED PAIN MORE THAN TWICE AS LONG AS INDIVIDUALLY MATCHED CONTROLS AND HAD MORE GRAY MATTER (GM) IN MULTIPLE BRAIN REGIONS. ACROSS SUBJECTS, INSULAR GM UNIQUELY CORRELATED WITH PAIN TOLERANCE. INSULAR GM VOLUME IN YOGIS POSITIVELY CORRELATED WITH YOGA EXPERIENCE, SUGGESTING A CAUSAL RELATIONSHIP BETWEEN YOGA AND INSULAR SIZE. YOGIS ALSO HAD INCREASED LEFT INTRAINSULAR WHITE MATTER INTEGRITY, CONSISTENT WITH A STRENGTHENED INSULAR INTEGRATION OF NOCICEPTIVE INPUT AND PARASYMPATHETIC AUTONOMIC REGULATION. YOGIS, AS OPPOSED TO CONTROLS, USED COGNITIVE STRATEGIES INVOLVING PARASYMPATHETIC ACTIVATION AND INTEROCEPTIVE AWARENESS TO TOLERATE PAIN, WHICH COULD HAVE LED TO USE-DEPENDENT HYPERTROPHY OF INSULAR CORTEX. TOGETHER, THESE FINDINGS SUGGEST THAT REGULAR AND LONG-TERM YOGA PRACTICE IMPROVES PAIN TOLERANCE IN TYPICAL NORTH AMERICANS BY TEACHING DIFFERENT WAYS TO DEAL WITH SENSORY INPUTS AND THE POTENTIAL EMOTIONAL REACTIONS ATTACHED TO THOSE INPUTS LEADING TO A CHANGE IN INSULAR BRAIN ANATOMY AND CONNECTIVITY.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
7 1439  22 INCREASED GREY MATTER ASSOCIATED WITH LONG-TERM SAHAJA YOGA MEDITATION: A VOXEL-BASED MORPHOMETRY STUDY. OBJECTIVES: TO INVESTIGATE REGIONAL DIFFERENCES IN GREY MATTER VOLUME ASSOCIATED WITH THE PRACTICE OF SAHAJA YOGA MEDITATION. DESIGN: TWENTY THREE EXPERIENCED PRACTITIONERS OF SAHAJA YOGA MEDITATION AND TWENTY THREE NON-MEDITATORS MATCHED ON AGE, GENDER AND EDUCATION LEVEL, WERE SCANNED USING STRUCTURAL MAGNETIC RESONANCE IMAGING AND THEIR GREY MATTER VOLUME WERE COMPARED USING VOXEL-BASED MORPHOMETRY. RESULTS: GREY MATTER VOLUME WAS LARGER IN MEDITATORS RELATIVE TO NON-MEDITATORS ACROSS THE WHOLE BRAIN. IN ADDITION, GREY MATTER VOLUME WAS LARGER IN SEVERAL PREDOMINANTLY RIGHT HEMISPHERIC REGIONS: IN INSULA, VENTROMEDIAL ORBITOFRONTAL CORTEX, INFERIOR TEMPORAL AND PARIETAL CORTICES AS WELL AS IN LEFT VENTROLATERAL PREFRONTAL CORTEX AND LEFT INSULA. NO AREAS WITH LARGER GREY MATTER VOLUME WERE FOUND IN NON-MEDITATORS RELATIVE TO MEDITATORS. CONCLUSIONS: THE STUDY SHOWS THAT LONG-TERM PRACTICE OF SAHAJA YOGA MEDITATION IS ASSOCIATED WITH LARGER GREY MATTER VOLUME OVERALL, AND WITH REGIONAL ENLARGEMENT IN SEVERAL RIGHT HEMISPHERIC CORTICAL AND SUBCORTICAL BRAIN REGIONS THAT ARE ASSOCIATED WITH SUSTAINED ATTENTION, SELF-CONTROL, COMPASSION AND INTEROCEPTIVE PERCEPTION. THE INCREASED GREY MATTER VOLUME IN THESE ATTENTION AND SELF-CONTROL MEDIATING REGIONS SUGGESTS USE-DEPENDENT ENLARGEMENT WITH REGULAR PRACTICE OF THIS MEDITATION.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  629  26 DIFFERENCES IN BRAIN STRUCTURE AND FUNCTION AMONG YOGA PRACTITIONERS AND CONTROLS. BACKGROUND: YOGA IS A MIND-BODY BASED PHYSICAL ACTIVITY THAT HAS DEMONSTRATED A VARIETY OF PHYSIOLOGICAL, PSYCHOLOGICAL AND COGNITIVE HEALTH BENEFITS. ALTHOUGH YOGA PRACTICE HAS SHOWN TO IMPROVE COGNITIVE PERFORMANCE, FEW STUDIES HAVE EXAMINED THE UNDERLYING NEUROLOGICAL CORRELATES. OBJECTIVE: THE CURRENT STUDY AIMED TO DETERMINE THE DIFFERENCES IN GRAY MATTER VOLUME OF THE HIPPOCAMPUS, THALAMUS AND CAUDATE NUCLEUS AND BRAIN ACTIVATION DURING THE STERNBERG WORKING MEMORY TASK. METHOD: PARTICIPANTS WERE 13 EXPERIENCED YOGA PRACTITIONERS (MEAN AGE = 35.8), DEFINED AS HAVING MORE THAN 3 YEARS OF REGULAR YOGA PRACTICE, AND 13 AGE- AND SEX-MATCHED CONTROLS (MEAN AGE = 35.7). ALL PARTICIPANTS COMPLETED A 6-MIN WALK TEST TO ASSESS FITNESS, PSYCHOSOCIAL AND DEMOGRAPHIC QUESTIONNAIRES; AND UNDERWENT MAGNETIC RESONANCE IMAGING TO ASSESS GRAY MATTER VOLUME AND BRAIN ACTIVATION. RESULTS: THERE WERE NO GROUP DIFFERENCES ON DEMOGRAPHIC MEASURES OF INCOME, EDUCATION AND ON ESTIMATED VO2MAX OR PHYSICAL ACTIVITY LEVELS. GRAY MATTER VOLUME DIFFERENCES WERE OBSERVED IN THE LEFT HIPPOCAMPUS, SHOWING GREATER VOLUME IN EXPERIENCED YOGA PRACTITIONERS COMPARED TO CONTROLS (P = 0.017). THE FUNCTIONAL MRI RESULTS REVEALED LESS ACTIVATION IN THE DORSOLATERAL PREFRONTAL CORTEX IN YOGA PRACTITIONERS COMPARED TO CONTROLS DURING THE ENCODING PHASE OF THE STERNBERG TASK (P < 0.05). REACTION TIME AND ACCURACY ON THE TASK DID NOT DIFFER BETWEEN THE GROUPS. CONCLUSIONS: OUR RESULTS SUGGEST AN ASSOCIATION BETWEEN REGULAR LONG-TERM YOGA PRACTICE AND DIFFERENTIAL STRUCTURE AND FUNCTION OF SPECIFIC BRAIN REGIONS INVOLVED IN EXECUTIVE FUNCTION, SPECIFICALLY WORKING MEMORY, WHICH HAS PREVIOUSLY SHOWN TO IMPROVE WITH YOGA PRACTICE. FUTURE STUDIES NEED TO EXAMINE INTERVENTION EFFECTS OF YOGA AND EXPLORE ITS POTENTIAL TO MAINTAIN AND IMPROVE COGNITIVE HEALTH ACROSS THE LIFESPAN THROUGH LONGITUDINAL AND INTERVENTION STUDIES.	2018	
                                                                                                                                                                                                                                      
9 1641  23 MONITORING THE NEURAL ACTIVITY OF THE STATE OF MENTAL SILENCE WHILE PRACTICING SAHAJA YOGA MEDITATION. OBJECTIVE: TO IDENTIFY THE NEURAL CORRELATES OF THE STATE OF MENTAL SILENCE AS EXPERIENCED THROUGH SAHAJA YOGA MEDITATION. DESIGN: NINETEEN EXPERIENCED MEDITATORS UNDERWENT FUNCTIONAL MAGNETIC RESONANCE IMAGING DURING THREE SHORT CONSECUTIVE MEDITATION PERIODS, CONTRASTED WITH A CONTROL RELAXATION CONDITION. RESULTS: RELATIVE TO BASELINE, AT THE BEGINNING OF THE MEDITATION SESSIONS THERE WAS A SIGNIFICANT INCREASE OF ACTIVATION IN BILATERAL INFERIOR FRONTAL AND TEMPORAL REGIONS. ACTIVATION BECAME PROGRESSIVELY MORE REDUCED WITH DEEPER MEDITATION STAGES AND IN THE LAST MEDITATION SESSION IT BECAME LOCALIZED TO THE RIGHT INFERIOR FRONTAL CORTEX/ RIGHT INSULA AND RIGHT MIDDLE/SUPERIOR TEMPORAL CORTEX. FURTHERMORE, RIGHT INFERIOR FRONTAL ACTIVATION WAS DIRECTLY ASSOCIATED WITH THE SUBJECTIVE DEPTH OF THE MENTAL SILENCE EXPERIENCE. CONCLUSIONS: MEDITATORS APPEAR TO PASS THROUGH AN INITIAL INTENSE NEURAL SELF-CONTROL PROCESS NECESSARY TO SILENCE THEIR MIND. AFTER THIS THEY EXPERIENCE RELATIVELY REDUCED BRAIN ACTIVATION CONCOMITANT WITH THE DEEPENING OF THE STATE OF MENTAL SILENCE OVER RIGHT INFERIOR FRONTAL CORTEX, PROBABLY REFLECTING AN EFFORTLESS PROCESS OF ATTENTIONAL CONTEMPLATION ASSOCIATED WITH THIS STATE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10 1105  42 EFFECTS OF YOGA VERSUS WALKING ON MOOD, ANXIETY, AND BRAIN GABA LEVELS: A RANDOMIZED CONTROLLED MRS STUDY. OBJECTIVES: YOGA AND EXERCISE HAVE BENEFICIAL EFFECTS ON MOOD AND ANXIETY. GAMMA-AMINOBUTYRIC ACID (GABA)-ERGIC ACTIVITY IS REDUCED IN MOOD AND ANXIETY DISORDERS. THE PRACTICE OF YOGA POSTURES IS ASSOCIATED WITH INCREASED BRAIN GABA LEVELS. THIS STUDY ADDRESSES THE QUESTION OF WHETHER CHANGES IN MOOD, ANXIETY, AND GABA LEVELS ARE SPECIFIC TO YOGA OR RELATED TO PHYSICAL ACTIVITY. METHODS: HEALTHY SUBJECTS WITH NO SIGNIFICANT MEDICAL/PSYCHIATRIC DISORDERS WERE RANDOMIZED TO YOGA OR A METABOLICALLY MATCHED WALKING INTERVENTION FOR 60 MINUTES 3 TIMES A WEEK FOR 12 WEEKS. MOOD AND ANXIETY SCALES WERE TAKEN AT WEEKS 0, 4, 8, 12, AND BEFORE EACH MAGNETIC RESONANCE SPECTROSCOPY SCAN. SCAN 1 WAS AT BASELINE. SCAN 2, OBTAINED AFTER THE 12-WEEK INTERVENTION, WAS FOLLOWED BY A 60-MINUTE YOGA OR WALKING INTERVENTION, WHICH WAS IMMEDIATELY FOLLOWED BY SCAN 3. RESULTS: THE YOGA SUBJECTS (N = 19) REPORTED GREATER IMPROVEMENT IN MOOD AND GREATER DECREASES IN ANXIETY THAN THE WALKING GROUP (N = 15). THERE WERE POSITIVE CORRELATIONS BETWEEN IMPROVED MOOD AND DECREASED ANXIETY AND THALAMIC GABA LEVELS. THE YOGA GROUP HAD POSITIVE CORRELATIONS BETWEEN CHANGES IN MOOD SCALES AND CHANGES IN GABA LEVELS. CONCLUSIONS: THE 12-WEEK YOGA INTERVENTION WAS ASSOCIATED WITH GREATER IMPROVEMENTS IN MOOD AND ANXIETY THAN A METABOLICALLY MATCHED WALKING EXERCISE. THIS IS THE FIRST STUDY TO DEMONSTRATE THAT INCREASED THALAMIC GABA LEVELS ARE ASSOCIATED WITH IMPROVED MOOD AND DECREASED ANXIETY. IT IS ALSO THE FIRST TIME THAT A BEHAVIORAL INTERVENTION (I.E., YOGA POSTURES) HAS BEEN ASSOCIATED WITH A POSITIVE CORRELATION BETWEEN ACUTE INCREASES IN THALAMIC GABA LEVELS AND IMPROVEMENTS IN MOOD AND ANXIETY SCALES. GIVEN THAT PHARMACOLOGIC AGENTS THAT INCREASE THE ACTIVITY OF THE GABA SYSTEM ARE PRESCRIBED TO IMPROVE MOOD AND DECREASE ANXIETY, THE REPORTED CORRELATIONS ARE IN THE EXPECTED DIRECTION. THE POSSIBLE ROLE OF GABA IN MEDIATING THE BENEFICIAL EFFECTS OF YOGA ON MOOD AND ANXIETY WARRANTS FURTHER STUDY.	2010	
                                                                                                                  
11 1670  22 NEUROPROTECTIVE EFFECTS OF YOGA PRACTICE: AGE-, EXPERIENCE-, AND FREQUENCY-DEPENDENT PLASTICITY. YOGA COMBINES POSTURES, BREATHING, AND MEDITATION. DESPITE REPORTED HEALTH BENEFITS, YOGA'S EFFECTS ON THE BRAIN HAVE RECEIVED LITTLE STUDY. WE USED MAGNETIC RESONANCE IMAGING TO COMPARE AGE-RELATED GRAY MATTER (GM) DECLINE IN YOGIS AND CONTROLS. WE ALSO EXAMINED THE EFFECT OF INCREASING YOGA EXPERIENCE AND WEEKLY PRACTICE ON GM VOLUME AND ASSESSED WHICH ASPECTS OF WEEKLY PRACTICE CONTRIBUTED MOST TO BRAIN SIZE. CONTROLS DISPLAYED THE WELL DOCUMENTED AGE-RELATED GLOBAL BRAIN GM DECLINE WHILE YOGIS DID NOT, SUGGESTING THAT YOGA CONTRIBUTES TO PROTECT THE BRAIN AGAINST AGE-RELATED DECLINE. YEARS OF YOGA EXPERIENCE CORRELATED MOSTLY WITH GM VOLUME DIFFERENCES IN THE LEFT HEMISPHERE (INSULA, FRONTAL OPERCULUM, AND ORBITOFRONTAL CORTEX) SUGGESTING THAT YOGA TUNES THE BRAIN TOWARD A PARASYMPATICALLY DRIVEN MODE AND POSITIVE STATES. THE NUMBER OF HOURS OF WEEKLY PRACTICE CORRELATED WITH GM VOLUME IN THE PRIMARY SOMATOSENSORY CORTEX/SUPERIOR PARIETAL LOBULE (S1/SPL), PRECUNEUS/POSTERIOR CINGULATE CORTEX (PCC), HIPPOCAMPUS, AND PRIMARY VISUAL CORTEX (V1). COMMONALITY ANALYSES INDICATED THAT THE COMBINATION OF POSTURES AND MEDITATION CONTRIBUTED THE MOST TO THE SIZE OF THE HIPPOCAMPUS, PRECUNEUS/PCC, AND S1/SPL WHILE THE COMBINATION OF MEDITATION AND BREATHING EXERCISES CONTRIBUTED THE MOST TO V1 VOLUME. YOGA'S POTENTIAL NEUROPROTECTIVE EFFECTS MAY PROVIDE A NEURAL BASIS FOR SOME OF ITS BENEFICIAL EFFECTS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12 2720  26 YOGA MEDITATION PRACTITIONERS EXHIBIT GREATER GRAY MATTER VOLUME AND FEWER REPORTED COGNITIVE FAILURES: RESULTS OF A PRELIMINARY VOXEL-BASED MORPHOMETRIC ANALYSIS. HATHA YOGA TECHNIQUES, INCLUDING PHYSICAL POSTURES (ASANAS), BREATHING EXERCISES (PRANAYAMA), AND MEDITATION, INVOLVE THE PRACTICE OF MINDFULNESS. IN TURN, YOGA MEDITATION PRACTICES MAY INDUCE THE STATE OF MINDFULNESS, WHICH, WHEN EVOKED RECURRENTLY THROUGH REPEATED PRACTICE, MAY ACCRUE INTO TRAIT OR DISPOSITIONAL MINDFULNESS. PUTATIVELY, THESE CHANGES MAY BE MEDIATED BY EXPERIENCE-DEPENDENT NEUROPLASTIC CHANGES. THOUGH PRIOR STUDIES HAVE IDENTIFIED DIFFERENCES IN GRAY MATTER VOLUME (GMV) BETWEEN LONG-TERM MINDFULNESS PRACTITIONERS AND CONTROLS, NO STUDIES TO DATE HAVE REPORTED ON WHETHER YOGA MEDITATION IS ASSOCIATED WITH GMV DIFFERENCES. THE PRESENT STUDY INVESTIGATED GMV DIFFERENCES BETWEEN YOGA MEDITATION PRACTITIONERS (YMP) AND A MATCHED CONTROL GROUP (CG). THE YMP GROUP EXHIBITED GREATER GM VOLUME IN FRONTAL, LIMBIC, TEMPORAL, OCCIPITAL, AND CEREBELLAR REGIONS; WHEREAS THE CG HAD NO GREATER REGIONAL GREATER GMV. IN ADDITION, THE YMP GROUP REPORTED SIGNIFICANTLY FEWER COGNITIVE FAILURES ON THE COGNITIVE FAILURES QUESTIONNAIRE (CFQ), THE MAGNITUDE OF WHICH WAS POSITIVELY CORRELATED WITH GMV IN NUMEROUS REGIONS IDENTIFIED IN THE PRIMARY ANALYSIS. LASTLY, GMV WAS POSITIVELY CORRELATED WITH THE DURATION OF YOGA PRACTICE. RESULTS FROM THIS PRELIMINARY STUDY SUGGEST THAT HATHA YOGA PRACTICE MAY BE ASSOCIATED WITH THE PROMOTION OF NEUROPLASTIC CHANGES IN EXECUTIVE BRAIN SYSTEMS, WHICH MAY CONFER THERAPEUTIC BENEFITS THAT ACCRUE WITH REPEATED PRACTICE.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
13  455  36 CHANGES IN NEURAL CONNECTIVITY AND MEMORY FOLLOWING A YOGA INTERVENTION FOR OLDER ADULTS: A PILOT STUDY. BACKGROUND: NO STUDY HAS EXPLORED THE EFFECT OF YOGA ON COGNITIVE DECLINE AND RESTING-STATE FUNCTIONAL CONNECTIVITY. OBJECTIVES: THIS STUDY EXPLORED THE RELATIONSHIP BETWEEN PERFORMANCE ON MEMORY TESTS AND RESTING-STATE FUNCTIONAL CONNECTIVITY BEFORE AND AFTER A YOGA INTERVENTION VERSUS ACTIVE CONTROL FOR SUBJECTS WITH MILD COGNITIVE IMPAIRMENT (MCI). METHODS: PARTICIPANTS ( >/= 55 Y) WITH MCI WERE RANDOMIZED TO RECEIVE A YOGA INTERVENTION OR ACTIVE "GOLD-STANDARD" CONTROL (I.E., MEMORY ENHANCEMENT TRAINING (MET)) FOR 12 WEEKS. RESTING-STATE FUNCTIONAL MAGNETIC RESONANCE IMAGING WAS USED TO MAP CORRELATIONS BETWEEN BRAIN NETWORKS AND MEMORY PERFORMANCE CHANGES OVER TIME. DEFAULT MODE NETWORKS (DMN), LANGUAGE AND SUPERIOR PARIETAL NETWORKS WERE CHOSEN AS NETWORKS OF INTEREST TO ANALYZE THE ASSOCIATION WITH CHANGES IN VERBAL AND VISUOSPATIAL MEMORY PERFORMANCE. RESULTS: FOURTEEN YOGA AND 11 MET PARTICIPANTS COMPLETED THE STUDY. THE YOGA GROUP DEMONSTRATED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN DEPRESSION AND VISUOSPATIAL MEMORY. WE OBSERVED IMPROVED VERBAL MEMORY PERFORMANCE CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE DMN AND FRONTAL MEDIAL CORTEX, PREGENUAL ANTERIOR CINGULATE CORTEX, RIGHT MIDDLE FRONTAL CORTEX, POSTERIOR CINGULATE CORTEX, AND LEFT LATERAL OCCIPITAL CORTEX. IMPROVED VERBAL MEMORY PERFORMANCE POSITIVELY CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE LANGUAGE PROCESSING NETWORK AND THE LEFT INFERIOR FRONTAL GYRUS. IMPROVED VISUOSPATIAL MEMORY PERFORMANCE CORRELATED INVERSELY WITH CONNECTIVITY BETWEEN THE SUPERIOR PARIETAL NETWORK AND THE MEDIAL PARIETAL CORTEX. CONCLUSION: YOGA MAY BE AS EFFECTIVE AS MET IN IMPROVING FUNCTIONAL CONNECTIVITY IN RELATION TO VERBAL MEMORY PERFORMANCE. THESE FINDINGS SHOULD BE CONFIRMED IN LARGER PROSPECTIVE STUDIES.	2016	
                                                                                                                                                                                                                                                                                                                           
14 1286  26 GRAY MATTER AND FUNCTIONAL CONNECTIVITY IN ANTERIOR CINGULATE CORTEX ARE ASSOCIATED WITH THE STATE OF MENTAL SILENCE DURING SAHAJA YOGA MEDITATION. SOME MEDITATION TECHNIQUES TEACH THE PRACTITIONER TO ACHIEVE THE STATE OF MENTAL SILENCE. THE AIM OF THIS STUDY WAS TO INVESTIGATE BRAIN REGIONS THAT ARE ASSOCIATED WITH THEIR VOLUME AND FUNCTIONAL CONNECTIVITY (FC) WITH THE DEPTH OF MENTAL SILENCE IN LONG-TERM PRACTITIONERS OF SAHAJA YOGA MEDITATION. TWENTY-THREE LONG-TERM PRACTITIONERS OF THIS MEDITATION WERE SCANNED USING MAGNETIC RESONANCE IMAGING. IN ORDER TO IDENTIFY THE NEURAL CORRELATES OF THE DEPTH OF MENTAL SILENCE, WE TESTED WHICH GRAY MATTER VOLUMES (GMV) WERE CORRELATED WITH THE DEPTH OF MENTAL SILENCE AND WHICH REGIONS THESE AREAS WERE FUNCTIONALLY CONNECTED TO UNDER A MEDITATION CONDITION. GMV IN MEDIAL PREFRONTAL CORTEX INCLUDING ROSTRAL ANTERIOR CINGULATE CORTEX WERE POSITIVELY CORRELATED WITH THE SUBJECTIVE PERCEPTION OF THE DEPTH OF MENTAL SILENCE INSIDE THE SCANNER. FURTHERMORE, THERE WAS SIGNIFICANTLY INCREASED FC BETWEEN THIS AREA AND BILATERAL ANTERIOR INSULA/PUTAMEN DURING A MEDITATION-STATE SPECIFICALLY, WHILE DECREASED CONNECTIVITY WITH THE RIGHT THALAMUS/PARAHIPPOCAMPAL GYRUS WAS PRESENT DURING THE MEDITATION-STATE AND THE RESTING-STATE. THE CAPACITY OF LONG-TERM MEDITATORS TO ESTABLISH A DURABLE STATE OF MENTAL SILENCE INSIDE AN MRI SCANNER WAS ASSOCIATED WITH LARGER GRAY MATTER VOLUME IN A MEDIAL FRONTAL REGION THAT IS CRUCIAL FOR TOP-DOWN COGNITIVE, EMOTION AND ATTENTION CONTROL. THIS IS FURTHERMORE CORROBORATED BY INCREASED FC OF THIS REGION DURING THE MEDITATION-STATE WITH BILATERAL ANTERIOR INSULA/PUTAMEN, WHICH ARE IMPORTANT FOR INTEROCEPTION, EMOTION, AND ATTENTION REGULATION. THE FINDINGS HENCE SUGGEST THAT THE DEPTH OF MENTAL SILENCE IS ASSOCIATED WITH MEDIAL FRONTO-INSULAR-STRIATAL NETWORKS THAT ARE CRUCIAL FOR TOP-DOWN ATTENTION AND EMOTIONAL CONTROL.	2018	
                                                                                                                                                                                                                                                                                                                    
15 1266  19 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16 2693  19 YOGA INCREASES THE VOLUME OF THE HIPPOCAMPUS IN ELDERLY SUBJECTS. CONTEXT: THE NEUROBIOLOGICAL EFFECT OF YOGA ON THE CORTICAL STRUCTURES IN THE ELDERLY IS AS YET UNKNOWN. MATERIALS AND METHODS: SEVEN HEALTHY ELDERLY SUBJECTS RECEIVED YOGA INTERVENTION AS AN ADD-ON LIFE-STYLE PRACTICE. MAGNETIC RESONANCE IMAGING SCANS WERE OBTAINED BEFORE AND 6 MONTHS LATER. VOXEL-BASED-MORPHOMETRIC ANALYSES COMPARED THE BRAINS BEFORE AND AFTER THE YOGA. RESULTS: YOGA GROUP WAS FOUND TO HAVE INCREASES IN HIPPOCAMPAL, BUT NOT IN OCCIPITAL GRAY MATTER. CONCLUSION: YOGA HAS POTENTIAL TO REDUCE NEURO-SENESCENCE. SMALL SAMPLE SIZE AND ABSENCE OF THE CONTROL GROUP PREVENT GENERALIZATION OF THE FINDINGS LIMITING ITS TRANSLATIONAL VALUE.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
17 1329  34 HIGH-FREQUENCY CEREBRAL ACTIVATION AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SUDARSHAN KRIYA YOGA AS GLOBAL BRAIN RHYTHMS: THE STATE EFFECTS. CONTEXT: RESPIRATION IS KNOWN TO MODULATE NEURONAL OSCILLATIONS IN THE BRAIN AND IS MEASURED BY ELECTROENCEPHALOGRAM (EEG). SUDARSHAN KRIYA YOGA (SKY) IS A POPULAR BREATHING PROCESS AND IS ESTABLISHED FOR ITS SIGNIFICANT EFFECTS ON THE VARIOUS ASPECTS OF PHYSIOLOGY AND PSYCHOLOGY. AIMS: THIS STUDY AIMED TO OBSERVE NEURONAL OSCILLATIONS IN MULTIFREQUENCY BANDS AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SKY. SETTINGS AND DESIGN: THIS STUDY EMPLOYED BEFORE- AND AFTER-STUDY DESIGN. SUBJECTS AND METHODS: FORTY HEALTHY VOLUNTEERS (AVERAGE AGE 25.45 +/- 5.75, 23 MALES AND 17 FEMALES) PARTICIPATED IN THE STUDY. NINETEEN-CHANNEL EEG WAS RECORDED AND ANALYZED FOR 5 MIN EACH: BEFORE AND AFTER SKY. SPECTRAL POWER FOR DELTA, THETA, ALPHA, BETA, AND GAMMA FREQUENCY BAND WAS CALCULATED USING MULTI-TAPER FAST FOURIER TRANSFORM (CHRONUX TOOLBOX). THE ASYMMETRY INDEX WAS CALCULATED BY SUBTRACTING THE NATURAL LOG OF POWERS OF LEFT (L) HEMISPHERE FROM THE RIGHT((R)) TO SHOW INTERHEMISPHERIC SYNCHRONIZATION. STATISTICAL ANALYSIS: PAIRED T-TEST WAS USED FOR STATISTICAL ANALYSIS. RESULTS: SPECTRAL POWER INCREASED SIGNIFICANTLY IN ALL FREQUENCY BANDS BILATERALLY IN FRONTAL, CENTRAL, PARIETAL, TEMPORAL, AND OCCIPITAL REGIONS OF THE BRAIN AFTER LONG SKY. ELECTRICAL ACTIVITY SHIFTED FROM LOWER TO HIGHER FREQUENCY RANGE WITH A SIGNIFICANT RISE IN THE GAMMA AND BETA POWERS FOLLOWING SKY. ASYMMETRY INDEX VALUES TENDED TOWARD 0 FOLLOWING SKY. CONCLUSIONS: A SINGLE SESSION OF SKY GENERATES GLOBAL BRAIN RHYTHM DOMINANTLY WITH HIGH-FREQUENCY CEREBRAL ACTIVATION AND INITIATES APPROPRIATE INTERHEMISPHERIC SYNCHRONIZATION IN BRAIN RHYTHMS AS STATE EFFECTS. THIS SUGGESTS THAT SKY LEADS TO BETTER ATTENTION, MEMORY, AND EMOTIONAL AND AUTONOMIC CONTROL ALONG WITH ENHANCED COGNITIVE FUNCTIONS, WHICH FINALLY IMPROVES PHYSICAL AND MENTAL WELL-BEING.	2020	
                                                                                                                                                                                                                                             
18  324  25 ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. OBJECTIVE: THIS STUDY AIMED TO EVALUATE ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL PARAMETERS IN CLIMACTERIC YOGA PRACTITIONERS. METHODS: THIS STUDY INVESTIGATED 108 CLIMACTERIC WOMEN. WE RECRUITED 28 WOMEN BETWEEN 40 AND 65 YEARS OLD WHO STARTED YOGA PRACTICES IN PREMENOPAUSE AND HAD ALREADY PRACTICED FOR AT LEAST 5 YEARS. AS CONTROLS, WE SELECTED 30 PHYSICAL ACTIVITY (PA) PRACTITIONERS WHO HAD PRACTICED FOR AT LEAST 5 YEARS AND 50 SEDENTARY WOMEN IN THE SAME AGE RANGE. WE CONDUCED ANTHROPOMETRIC, BIOCHEMICAL AND BLOOD PRESSURE MEASUREMENTS. RESULTS: THE YOGA GROUP HAD SIGNIFICANTLY LOWER FASTING BLOOD GLUCOSE THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. YOGA PRACTITIONERS ALSO HAD LOWER WEIGHT, BODY MASS INDEX, WAIST CIRCUMFERENCE, BODY FAT PERCENTAGE AND WAIST-TO-HEIGHT RATIO; HIGHER LEVELS OF HIGH-DENSITY LIPOPROTEIN CHOLESTEROL; LOWER LEVELS OF TRIGLYCERIDES, INSULIN, HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE, URIC ACID, APOLIPOPROTEIN B AND HIGH-SENSITIVITY C-REACTIVE PROTEIN; AND LOWER FREQUENCY OF METABOLIC SYNDROME, LIPID ACCUMULATION PRODUCT, VISCERAL ADIPOSITY INDEX AND SYSTOLIC BLOOD PRESSURE THAN THE SEDENTARY WOMEN. CONCLUSION: YOGA PRACTITIONERS HAD LOWER GLUCOSE SERUM CONCENTRATIONS THAN THE PA PRACTITIONERS AND SEDENTARY WOMEN. OVERALL, THE YOGA GROUP ALSO HAD BETTER ANTHROPOMETRIC, BIOCHEMICAL AND CLINICAL VARIABLES THAN THE OTHER GROUPS. ALTHOUGH FURTHER INVESTIGATION IS REQUIRED, YOGA PRACTICE IN PREMENOPAUSE SEEMS TO BE BENEFICIAL FOR WOMEN WHEN THEY REACH MENOPAUSE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
19  176  33 A RANDOMIZED CONTROLLED TRIAL OF KUNDALINI YOGA IN MILD COGNITIVE IMPAIRMENT. BACKGROUND: GLOBAL POPULATION AGING WILL RESULT IN INCREASING RATES OF COGNITIVE DECLINE AND DEMENTIA. THUS, EFFECTIVE, LOW-COST, AND LOW SIDE-EFFECT INTERVENTIONS FOR THE TREATMENT AND PREVENTION OF COGNITIVE DECLINE ARE URGENTLY NEEDED. OUR STUDY IS THE FIRST TO INVESTIGATE THE EFFECTS OF KUNDALINI YOGA (KY) TRAINING ON MILD COGNITIVE IMPAIRMENT (MCI). METHODS: OLDER PARTICIPANTS (>/=55 YEARS OF AGE) WITH MCI WERE RANDOMIZED TO EITHER A 12-WEEK KY INTERVENTION OR MEMORY ENHANCEMENT TRAINING (MET; GOLD-STANDARD, ACTIVE CONTROL). COGNITIVE (I.E. MEMORY AND EXECUTIVE FUNCTIONING) AND MOOD (I.E. DEPRESSION, APATHY, AND RESILIENCE) ASSESSMENTS WERE ADMINISTERED AT BASELINE, 12 WEEKS AND 24 WEEKS. RESULTS: AT BASELINE, 81 PARTICIPANTS HAD NO SIGNIFICANT BASELINE GROUP DIFFERENCES IN CLINICAL OR DEMOGRAPHIC CHARACTERISTICS. AT 12 WEEKS AND 24 WEEKS, BOTH KY AND MET GROUPS SHOWED SIGNIFICANT IMPROVEMENT IN MEMORY; HOWEVER, ONLY KY SHOWED SIGNIFICANT IMPROVEMENT IN EXECUTIVE FUNCTIONING. ONLY THE KY GROUP SHOWED SIGNIFICANT IMPROVEMENT IN DEPRESSIVE SYMPTOMS AND RESILIENCE AT WEEK 12. CONCLUSION: KY GROUP SHOWED SHORT- AND LONG-TERM IMPROVEMENTS IN EXECUTIVE FUNCTIONING AS COMPARED TO MET, AND BROADER EFFECTS ON DEPRESSED MOOD AND RESILIENCE. THIS OBSERVATION SHOULD BE CONFIRMED IN FUTURE CLINICAL TRIALS OF YOGA INTERVENTION FOR TREATMENT AND PREVENTION OF COGNITIVE DECLINE (NCT01983930).	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
20 1012  28 EFFECTS OF ONE MONTH OF COMMON YOGA PROTOCOL PRACTICE APPEAR TO BE MEDIATED BY THE ANGIOGENIC AND NEUROGENIC PATHWAY: A PILOT STUDY. OBJECTIVE: TO EXAMINE THE MOLECULAR EFFECTS OF MINDFUL ACTIVITIES SUCH AS YOGA AND MEDITATION DESIGN: THIS WAS AN OPEN LABEL SINGLE ARM EXPLORATORY YOGA INTERVENTION STUDY. STUDY PARTICIPANTS: 64 HEALTHY INDIVIDUALS WITHIN THE AGE OF 18-60 YEARS WERE RECRUITED FOR THIS ONE MONTH YOGA INTERVENTION STUDY. INTERVENTION: COMMON YOGA PROTOCOL (CYP) IS A STANDARDIZED YOGA PROTOCOL RELEASED BY MINISTRY OF AYUSH, INDIA FOR INTERNATIONAL YOGA DAY. IT INCLUDES ALL ASPECTS OF YOGA I.E. ASANAS, PRANAYAMA AND MEDITATION. IT IS DESIGNED FOR ADOPTION BY ALL AGE GROUPS FOR THE HEALTH OF COMMUNITY. OUTCOME MEASURES: THE PARTICIPANTS WERE ASSESSED FOR BIOCHEMICAL PARAMETERS INCLUDING FASTING SUGAR AND LIPID PROFILE. THE MOLECULAR MARKERS OF NEUROGENESIS (I.E. BRAIN DERIVED NEUROTROPIC FACTOR, BDNF) AND ANGIOGENESIS (I.E. VASCULAR ENDOTHELIAL GROWTH FACTOR, VEGF AND ANGIOGENIN) ALONG WITH AMYLOID BETA (MARKER RELATED TO NEURO-DEGENERATIVE DISEASES) WERE ASSESSED. ALL THE ASSESSMENTS WERE MADE AT BASELINE AND AFTER ONE MONTH OF THE INTERVENTION. RESULTS: AFTER ONE MONTH OF CYP PRACTICE HIGH DENSITY LIPOPROTEIN (HDL) LEVELS INCREASED SIGNIFICANTLY (P<0.001), ALTHOUGH OTHER BIOCHEMICAL PARAMETERS I.E. FASTING SUGAR AND OTHER LIPID ASSESSMENTS WERE FOUND TO BE UNALTERED. ANGIOGENESIS MARKER, ANGIOGENIN WAS INCREASED SIGNIFICANTLY (P<0.002), OTHER ANGIOGENESIS MARKER VEGF DID NOT SHOW ANY CHANGE ALONG WITH BDNF, MARKER OF NEUROGENESIS. AMYLOID BETA LEVELS WERE ALSO UNALTERED. EVEN THOUGH INDIVIDUAL LEVELS OF VEGF AND AMYLOID BETA DID NOT SHOW ANY CHANGE, PROPORTION OF VEGF TO AMYLOID BETA SHOWED A SIGNIFICANT INCREASE (P<0.001) AFTER ONE MONTH OF CYP INTERVENTION INDICATING THAT THE CHANGE IN VEGF LEVELS WAS SIGNIFICANTLY HIGHER THAN THE CHANGE IN AMYLOID BETA LEVELS. CONCLUSION: CYP PRACTICE MAY INFLUENCE CELL SURVIVAL PATHWAYS MEDIATED BY ANGIOGENIC AND NEUROGENIC CROSS TALK. HENCE, CYP CAN BE CONSIDERED AS A PREVENTIVE MEASURE FOR DISEASES ASSOCIATED WITH IMPAIRED ANGIOGENIC AND NEUROGENIC MECHANISM. THIS IS THE FIRST STUDY TO EXAMINE THE EFFECTS OF CYP AT THE MOLECULAR LEVEL.	2021
