Direct Observation of Phase Change Accommodating Hydrogen Uptake in Bimetallic Nanoparticles.

Hydrogen holds great promise as a cleaner alternative to fossil fuels, but its efficient and affordable storage remains a significant challenge. Bimetallic systems, such as Pd and Ni, present a promising option for storing hydrogen. In this study, using the combination of different cutting-edge X-ray and electron techniques, we observed the transformations of Pd-Ni nanoparticles, which initially consist of a NiO-rich shell surrounding a Pd-rich core but undergo a major transformation when they interact with hydrogen.

Drone-based medical delivery in the extreme conditions of Himalayan region: a feasibility study.

Introduction: Unmanned aerial vehicles, or drones, have emerged as versatile tools across various sectors, including defence, agriculture, surveillance, mining, infrastructure, emergency response, transportation, geospatial mapping and notably medical supply delivery to challenging terrains. This study aims to investigate the feasibility of using drones for delivering essential medical supplies in Keylong, Himachal Pradesh, situated amidst the Middle Himalayan Range, where heavy snowfall during peak winter restricts access to remote regions, posing logistical hurdles for healthcare provision.

Methods: This cross-sectional used a mixed-method approach alongside assessing the drone-based medical delivery.

Factor XI and XII inhibitors-Dawn of a new era.

The history of coagulation cascade dates back to 17th century. The extrinsic and intrinsic pathways were proposed in 1998. Extrinsic pathway includes the tissue factor and stable factor which activates factor X and with help of factor V, this converts prothrombin to thrombin which is stabilised by factor XIII.

Pathogenesis, attenuation, and treatment strategies for keloid management.

Keloid is an outcome of abnormal cellular response in the wound healing process with excessive fibroblast and collagen deposition in the dermal layer of the skin. It is characterized by a scar showing fibrous outgrowth that grows beyond the original boundaries of the wound. Thus, it is cosmetically and functionally disturbing to the patient.

Prolonged administration of letrozole induces polycystic ovary syndrome leading to osteoporosis in rats: model development and validation studies.

Polycystic ovary syndrome (PCOS) mainly affects women of reproductive age. Clinical studies suggest a link between PCOS and osteoporosis (OP). Our goal was to explore the correlation between the two.
