Background: "Himalayan P waves," are reported in congenital heart disease and cardiomyopathies.
Methods: We report a family with hypertrophic cardiomyopathy, Himalayan P waves, extensive focal right atrial wall thickening and left ventricular hypertrabeculation/noncompaction (LVHT).
Results: The father received a pacemaker and underwent heart transplantation because of hypertrophic cardiomyopathy. His daughters showed Himalayan P waves and right atrial wall thickening. LVHT was diagnosed in sister A at age 23 years and developed in sister B between 42 and 46 years. In sister A the heart rate continuously declined. She refused implantation of a pacemaker and died with 49 years. Sister B, suffers from bradycardia.
Conclusions: Himalayan P waves are due to focal right atrial wall thickening, may be familially and associated with LVHT.

The study aimed to extract and encapsulate betalain pigment from prickly pear (Opuntia ficus-indica) using ultrasound-assisted extraction and eco-friendly glycerol. Subsequent analysis encompassed assessing its thermal stability, shelf-life, bio-accessibility, and biological properties. The process optimization employed Response Surface Methodology (RSM), focusing on glycerol concentration (20-50 %), sample to solvent ratio (1:10-1:20), temperature (30-60 °C), and time (10-30 min).

India had faced three waves throughout the Coronavirus disease 2019 (COVID-19) pandemic, which had already impacted economic lives and affected the healthcare setting and infrastructure. The widespread impacts have inspired researchers to look for clinical indicators of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection prognosis. Cyclic threshold values have been used to correlate the viral load in COVID-19 patients and for viral transmission.

Spatiotemporal analysis is a critical tool for understanding COVID-19 spread. This study examines the pattern of spatial distribution of COVID-19 cases across India, based on data provided by the Indian Council of Medical Research (ICMR). The research investigates temporal patterns during the first, second, and third waves in India for an informed policy response in case of any present or future pandemics.

The cases of infection in India have remained low, despite the continued surge of Omicron sub-lineages reported in a few countries. In this study, we determined the presence of the circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains in the population of Kangra District, Himachal Pradesh, India.

The earthquake hazard associated with the Main Himalayan Thrust (MHT) is a critical issue for India and its neighbouring countries in the north. We used data from a dense seismic network in Uttarakhand, India, to model the lateral variations in the depths of MHT (2-6% drop in V at 12-21 km depths), Moho (a sharp increase in V (by ~ 0.5-0.
