Abstract
Objective: We aimed to study the short-term effects of Integrated Amrita Meditation (IAM) technique in anxiety and depression states and to have a better understanding on the underlying physiological changes related to short-term and long-term IAM practice. Design: Short-term IAM practitioners (ST-IAM) and long-term IAM practitioners (LT-IAM) were compared to control groups of the same age and naïve to yoga and meditation (ST-control and LT-control, respectively). Settings/Location: Kerala, India. Subjects: People that did not suffer from any major medical condition. All participants were naïve to yoga and meditation practices, except for the 5 LT-IAM practitioners. Intervention: ST-IAM practitioners underwent 2 community IAM practices and 5 individual IAM practices. LT-IAM practitioners (performing IAM regularly for more than 4 years) underwent a community IAM practice before the study. Outcome measures: Anxiety and depression states and physiological parameters from ST-IAM and ST-control groups were assed in two different visits (before and after the week of IAM practice or control condition). LT-IAM and LT-control subjects' physiological measurements were taken in only one visit. Results: Short-term IAM practice significantly decreased anxiety and depression states; two way ANOVA indicated differences on anxiety and depression scores across visits between ST-IAM and ST-control groups (Group effect: F(1, 25) = 6.083, p = 0.0209; F(1, 25) = 4.449, p = 0.0451). However, no changes were observed on their physiological parameters (heart rate, blood pressure, oxygen saturation, and dopamine and GABA plasma levels). Interestingly, LT-IAM practitioners showed increased GABA plasma levels than the LT-control group (p = 0.0358, t = 2.521, df = 8). Conclusions: Our study indicates the possible role of IAM technique on modulations of the plasma GABAergic levels and shows that one week of IAM practice is accompanied by a significant decrease of anxiety and depression states in the healthy population.

Abstract
Experiencing pain, especially when chronic, is an excruciating condition that should be regarded as a syndrome, if not a disease. People suffering from chronic pain tend to develop psychological discomfort mostly due to lack of acceptance, disbelief, blame. The complexity of pain pathophysiology, plus a wide range of negative psychosocial factors, leads to a more complex suffering that deserves attention and multidisciplinary treatments. The possibility that chronic pain may occur following physical aggression, torture, or persecution raises the issue of evil as a major contributor to pain in its worst representation - when individuals or groups are attacked based on racial, social, gender, religious, political, or other grounds. To explore the complex issue of chronic pain following physical or psychological harm, and to underscore the need for a multidisciplinary approach to reduce the burden of chronic pain, we discuss the biological mechanisms underlying pain state. We seek to clarify those factors leading to pain chronification, as well as personal and social attitudes that confound patients with chronic pain. The importance of family and social environment is also investigated, as well as personality traits of chronic pain patients that may further hamper successful treatment. The presence of chronic pain, modulated by, for example, acceptance of being a victim of premeditated physical and social violence, makes the issue more difficult to comprehend.

Abstract
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.

Abstract
Chronic pain, the most common complication of diabetes, is treated with medication often to no avail. Our study aimed to compare the use of mindfulness meditation and progressive relaxation to reduce chronic pain in older females with diabetes. Methods The 105 study participants were divided randomly into 3 groups: Group MM (mindfulness meditation), Group CM (control meditation), and Group PM (progressive relaxation meditation). Assessment of analgesic effectiveness required changes in average daily pain Brief Pain Inventory (BPI) modified for painful diabetic peripheral neuropathy and Patient Global Impression of Change using descriptive statistics, Student's t test, and analysis of variance where applicable. Results Both Groups MM and PM experienced significant (P < .05) reduction in average daily pain in last 24 hours at study end compared to baseline (28.7% and 39.7%, respectively). Group MM had more significant (P < .01) reduction of pain compared to control, a score of 5.2 ± 1.2 dropped to 3.0 ± 1.1 by week 12 of treatment. Groups MM and PM showed significant improvement in patients' impression at study end, 75 ± 5.1% (n = 36) and 61 ± 6.5% (n = 32), respectively. In Group MM, patient satisfaction scores increased significantly (P < .05) to 3.8 ± 1.9 by week 12. Conclusion Integrative therapies such as mindfulness meditation can be part of a comprehensive pain management plan. Benefits include reduction of pain-related medication consumption, better treatment outcomes, improvement in comorbid conditions such as anxiety and depression as well as no risk of addiction or abuse.

Abstract
Meditation is a complex process involving change in cognition, memory, and social and emotional control, and causes improvement in various cardiovascular, neurological, autoimmune, and renal pathologies. Meditation also become widely used in medical and psychological treatment therapies for stress-related physical and mental disorders. But still, biological mechanisms in terms of effect on brain and body are poorly understood. This paper explains the basic changes due to meditation in cerebral cortex, prefrontal area, cingulate gyrus, neurotransmitters, white matter, autonomic nervous system, limbic system, cytokines, endorphins, hormones, etc. The following is a review of the current literature regarding the various neurophysiological mechanisms, neuro-endocrine mechanisms, neurochemical substrates, etc. that underlies the complex processes of meditation.

Abstract
The practice of yoga regulates body physiology through control of posture, breathing, and meditation. Effects of yoga on autonomic functions of patients with refractory epilepsy, as quantified by standardized autonomic function tests (AFTs), were determined. The yoga group (n=18) received supervised training in yoga, and the exercise group (n=16) practiced simple routine exercises. AFTs were repeated after 10 weeks of daily sessions. Data were compared with those of healthy volunteers (n=142). The yoga group showed significant improvement in parasympathetic parameters and a decrease in seizure frequency scores. There was no improvement in blood pressure parameters in either group. Two patients in the yoga group achieved normal autonomic functions at the end of 10 weeks of therapy, whereas there were no changes in the exercise group. The data suggest that yoga may have a role as an adjuvant therapy in the management of autonomic dysfunction in patients with refractory epilepsy.

Abstract
Brain Respiration (BR)-training is a unique form of breathing exercise that develops potential ability by facilitating brain function. It is recognized as an effective method of improving the scholastic aptitude and emotional stability of children. The present study was designed to investigate the characteristics of the EEG during this training. Spectral analysis was used to examine the relative power in the EEG of 12 children while they practiced BR-training, and these were compared to those of 12 matched controls. BR-trainees showed a lower theta rhythm than the controls before the training session began and lower beta2 power before, during and after the session. In contrast, the BR subjects showed greater relative alpha1 power than the controls in the left frontal region during BR-training, which persisted throughout the BR-training schedule. There is evidence that decreased theta and beta waves may be correlated with emotional maturation, whilst increased alpha waves are associated with educational achievement. These findings enhance our understanding of the neurophysiological basis of the effects of BR-training upon emotion and maturation.

Abstract
Transcendental meditation (TM) is a stylized form of physical and mental relaxation which is associated with changes in the secretion and release of several pituitary hormones. The hormonal changes induced by TM mimic the effects of the inhibitory neurotransmitter gamma aminobutyric acid (GABA). It is hypothesized that TM produces changes in pituitary hormone secretion by enhancing hypothalamic GABAergic tone as a result of TM associated ketosis. Ketosis enhances the entry of glutamate, the amino acid substrate of GABA into synaptosomes, making more glutamate available for conversion to GABA through the glutamate decarboxylase pathway.

Abstract
OBJECTIVE Increased peripheral vasoconstriction (ie, total peripheral resistance, or TPR) has been implicated as playing an important role in the early development of essential hypertension. Some studies have demonstrated that Transcendental Meditation (TM) reduces high blood pressure, but the hemodynamic adjustments behind these blood pressure reductions have not been elucidated. The aim of this study was to provide a preliminary investigation of the acute effects of TM on TPR. METHODS Subjects were 32 healthy adults (16 women and 16 men; 30 white and two African American; mean age, 46.4 +/- 3.9 years). Subjects were divided into a TM group of long-term TM practitioners (eight white women, nine white men, and one African American man; mean years of twice-daily TM practice, 22.4 +/- 6.7) and a control group (eight white women, five white men, and one African American man). Hemodynamic functioning was assessed immediately before and during three conditions: 20 minutes of rest with eyes open (all subjects), 20 minutes of TM (TM group), and 20 minutes of eyes-closed relaxation (control group). RESULTS During eyes-open rest, the TM group had decreases in systolic blood pressure (SBP) and TPR, compared with increases in the control group (SBP: -2.5 vs. +2.4 mm Hg, p < .01; TPR: -0.7 vs. +0.5 mm Hg/liter per minute, p < .004). During TM, there was a greater decrease in SBP due to a concomitantly greater decrease in TPR compared with the control group during eyes-closed relaxation (SBP: -3.0 vs. +2.1 mm Hg, p < .04; TPR: -1.0 vs. +0.3 mm Hg/liter per minute, p < .03). CONCLUSIONS TPR decreased significantly during TM. Decreases in vasoconstrictive tone during TM may be the hemodynamic mechanism responsible for reduction of high blood pressure over time. The results of this study provide a preliminary contribution to the understanding of the underlying hemodynamic mechanisms responsible for the beneficial influence of TM on cardiovascular risk factors.

Abstract
We have evaluated the effect of Transcendental Meditation (TM) on the hypothalamo-hypophyseal-adrenal axis diurnal rhythms through the determination of hormone levels. Blood samples were taken at 0900 hours. and at 2000 hours. These samples were taken from 18 healthy volunteers who regularly practice TM and from nine healthy non-meditators. Cortisol, beta-endorphin, and adrenocorticotropic hormone (ACTH) were measured at both hours. TM practitioners showed no diurnal rhythm for ACTH and for beta-endorphin (ACTH, pg/mL, mean +/- SE; 13.8+/-1.2 - 12.1+/-1.5/beta-endorphin, pg/mL; 14.4+/-1.5 - 17.2+/-1.9, at 0900 hours and 2000 hours, respectively), in contrast to control subjects, who showed normal diurnal rhythm for these hormones and for cortisol (ACTH, pg/mL; 19.4+/-1.9 - 11.9+/-2.2/beta-endorphin, pg/mL; 25.4+/-1.7 - 17.7+/-1.1/Cortisol, ng/mL; 201.4+/-13.2 - 71.3+/-6.5, at 0900-2000 hours, respectively, p < 0.01 in the three cases). Practitioners of TM with similar anxiety levels to those of the control group showed a different pattern in the daytime secretion of pituitary hormones. TM thus appears to have a significant effect on the neuroendocrine axis. Because cortisol levels had a normal pattern in the TM group, these results may be due to a change in feedback sensitivity caused by this mental technique.

Abstract
Our objective was to test the short-term efficacy and feasibility of two stress-reduction approaches for the treatment of hypertension in older African Americans, focusing on subgroup analysis by sex and by high and low risk on six measures of hypertension risk: psychosocial stress, obesity, alcohol use, physical inactivity, dietary sodium-potassium ratio, and a composite measure. The study involved a follow-up subgroup analysis of a 3-month randomized, controlled, single-blind trial conducted in a primary care, inner-city health center. Subjects were 127 African American men and women, aged 55 to 85 years, with diastolic pressure of 90 to 104 mm Hg and systolic pressure less than or equal to 179 mm Hg. Of these, 16 did not complete follow-up blood pressure measurements. Mental and physical stress-reduction approaches-the Transcendental Meditation technique and progressive muscle relaxation, respectively-were compared with a life-style modification education control and with each other. Both systolic and diastolic pressures changed from baseline to follow-up for both sexes and for high and low risk level (defined by median split) on the six measures of hypertension risk. Compared with education control subjects, women practicing the Transcendental Meditation technique showed adjusted declines in systolic (10.4 mm Hg, P < .01) and diastolic (5.9 mm Hg, P < .01) pressures. Men in this treatment group also declined in both systolic (12.7 mm Hg, P < .01) and diastolic (8.1 mm Hg, P < .001) pressures compared with control subjects. Women practicing muscle relaxation did not show a significant decrease compared with control subjects, and men declined significantly in diastolic pressure only (6.2 mm Hg, P < .01). For the measure of psychosocial stress, both the high and low risk subgroups using the Transcendental Meditation technique declined in systolic (high risk, P = .0003; low, P = .06) and diastolic (high risk, P = .001; low, P = .008) pressures compared with control subjects, whereas for muscle relaxation, blood pressure dropped significantly only in the high risk subgroup and only for systolic pressure (P = .03) compared with control subjects. For each of the other five risk measures, Transcendental Meditation subjects in both the high and low risk groups declined significantly in systolic and diastolic pressures compared with control subjects. Effects of stress reduction on blood pressure were found to generalize to both sexes and diverse risk factor subgroups and were significantly greater in the Transcendental Meditation treatment group. These effects (along with high compliance) even in individuals with multiple risk factors for hypertension clearly warrant longer-term investigation in this and other populations.
