Background: is a fast pace respiratory exercise or , which is supposed to be practiced by yogis to clean their brain. are well known to improve heart rate variability (HRV) ultimately leading to better autonomic functions. Other studies have observed the immediate effect of on various neurological (brain and spine) and autonomic functions, but their results are varied and inconclusive.
Objective: The aim of this study is to find out the changes in HRV and brain waves during and after practice of as compared with the baseline values of different parameters.
Methods: Various parameters were measured at baseline, during and after with the help of Dinamika HRV-Advanced HRV Test System, Moscow, Russia. Statistical analysis was accomplished employing repeated measures analysis of variance with Bonferroni post-hoc analysis and Holm's multiple comparisons using the Version 28.0.0.0 of the Statistical Package for the Social Sciences (SPSS) for Windows (190) SPSS Inc., Chicago.
Results: We found that during and after , changes in HRV were significant in time and frequency domain showing parasympathetic withdrawal and insignificant changes in brain waves as compared with reference point values.
Conclusion: is initially energizing, cleansing, and heating. There occurs parasympathetic withdrawal and sympathetic activation during . There is an increase gamma wave activation post showing control of the default mode network.

Background: Cardiac autonomic neuropathy (CAN) is a significant complication in chronic kidney disease (CKD), leading to increased morbidity and mortality. Early detection is essential for managing CKD patients effectively, especially those on hemodialysis. This study evaluated the prevalence CAN in CKD and diagnostic accuracy of Bellavere's Score in predicting CAN in CKD patients, including those undergoing hemodialysis.

Objective: Imbalanced autonomic nervous system (ANS) activity raises concerns about the development of systemic complications during dental treatment. The purpose of this study was to determine whether a psychological test (Toho Medical Index (TMI)) prior to the impacted mandibular third molar extraction can identify patients with potentially imbalanced autonomic function.
Materials And Methods: In this prospective study, 34 healthy adult patients with no history of systemic disease were assigned to either the autonomic imbalance group (type II, III, IV) or the control group (type I) based on the results of the TMI.

Chemotherapy-induced peripheral neuropathy is a debilitating pain condition resulting from cancer treatment and is known to be associated with a decrease in health-related quality of life. This single-center cross-sectional study, conducted at Institute of Nuclear Medicine Oncology and Radiotherapy (INOR), Abbottabad, Pakistan, assessed the prevalence and severity of chemotherapy-induced peripheral neuropathy and its impact on quality of life in cancer patients undergoing chemotherapy. Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-CIPN20 questionnaires.
