Effects of yoga breathing practice on heart rate variability in healthy adolescents: a randomized controlled trial

This study was conducted among healthy adolescents to assess the effects of a yoga breathing practice (Bhramari pranayama, Bhr.P) towards cardiac autonomic function using heart rate variability (HRV) parameters.MethodsOf the 730 eligible subjects screened, 520 healthy adolescents who met the inclusion and exclusion criteria were randomly assigned to either yoga breathing group (n = 260) or control group (n = 260). The yoga breathing group practiced Bhr.P. five days a week for a duration of six months while the control group continued with their daily routine without any intervention. Outcome measures were time and frequency domain of HRV in both groups which were assessed before and after the intervention using Lead II ECG. Linear models were used in the analysis of short term HRV.ResultsAfter 6 months of yoga breathing, the time domain parameters of short term HRV showed significant (P

There have been several hypotheses developed to elucidate the mechanisms behind these findings. It is well documented that cold represents a very efficient stressor that activates sympathetic nerves and increases tissue and plasma norepinephrine levels. Importantly, recently accumulated data indicate that norepinephrine c...

Authors: Park TH, Lee JB, Lee HJ, Yun B Abstract The purpose of this study was to quantitatively assess the difference in sudomotor function between healthy males and females in their early twenties by measuring skin surface area and activated sweat gland density (ASGD). The quantitative sudomotor axon reflex test (QSART), a method for evaluating autonomic nervous system activity, was used for quantification. In QSART, the sweat glands are activated directly or indirectly by the subcutaneous application of neurotransmitters, such as acetylcholine, through iontophoresis. This series of mechanisms is called the sudom...

Conclusions: RPE atrophy progresses along with a loss of photoreceptors, and parafoveal RPE hypoautofluorescence is commonly seen in KIZ-associated RP patients. KIZ-associated RP is an early-onset severe rod-cone dystrophy. PMID: 32052671 [PubMed - as supplied by publisher]

Previous studies have demonstrated that human elbow muscles express an inter-limb stretch reflex at long-latency (50-100 ms), a timing consistent with a trans-cortical linkage. Here we probe for inter-limb stretch reflexes in the shoulder muscles of human participants. Unexpected torque pulses displaced one or both shoulders while participants adopted a steady posture against background torques. The results dem...

Cardiac involvements in DM1 are characterized by cardiac conduction delays and atrial or ventricular tachycardia, which increase the risk of sudden cardiac death when compared with general population. Only a fe...

ABSTRACT Objective: To present a case of bilateral gynecomastia in a prepubertal boy with autism spectrum disorder, diagnosed with myotonic dystrophy type 1. Case description: A 12-year-old boy with autism spectrum disorder presented at a follow-up visit with bilateral breast growth. There was a family history of gynecomastia, cataracts at a young age, puberty delay, and myotonic dystrophy type 1. The physical examination showed that he had bilateral gynecomastia with external genitalia Tanner stage 1. Neurologic examination was regular, without demonstrable myotonia. The analytical study revealed increased estradiol level...

Myotonic dystrophy type 1 is a neuromuscular disease, characterized by a progressive loss of strength, muscle stiffness, and difficulty in relaxation. Myotonic dystrophy type 1 patients can present several neuropsychological deficits, as well as anxiety and mood disorders. Aim of this study is to evaluate the feasibility and the effect of virtual reality in the cognitive and behavioral recovery of myotonic dystrophy type 1 patients. Eleven patients (8 female and 3 male) underwent a specific cognitive rehabilitation program including a conventional neuropsychological treatment followed by a virtual reality neurorehabilitati...
