Insights into periplasmic nitrate reductase function under single turnover.

Nitrate reductases play pivotal roles in nitrogen metabolism by leveraging the molybdopterin cofactor to facilitate the reduction of nitrate to nitrite. Periplasmic nitrate reductases (NapA) utilize nitrate as a terminal electron acceptor when oxygen is limiting, helping to drive anaerobic metabolism in bacteria. Despite extensive research into NapA homologs, open questions about the mechanism remain especially at the molecular level.

Surface elemental and structural analysis of ancient Indian punch-marked coins (600 to 200 BCE): insights into metallurgy and economic practices.

Punch-marked coins (PMCs) are the oldest coins in India and among the most widely circulated globally, often found in hoards that highlight their extensive use. This study utilizes X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) to analyze the surface elemental composition and chemical properties of nine series (S-0 to S-VIII) of Janapada (S-0) and imperial PMCs (S-1 to S-VIII) dating from 600 to 200 BCE, housed in the Numismatic Society of India at BHU, Varanasi, based on the Gupta-Hardakar classification related to the PMCs. XRD results reveal four prominent diffraction peaks corresponding to metallic silver (Ag) in the face-centred cubic (fcc) phase, with a slight variation in d-spacing (∼ 0.

Identification of biallelic POLA2 variants in two families with an autosomal recessive telomere biology disorder.

POLA2 encodes the accessory subunit of DNA polymerase α (polα)/primase, which is crucial for telomere C-strand fill-in. Incomplete fill-in of the C-rich telomeric strand after DNA replication has been proposed as a mechanism for Coats plus syndrome, a phenotype within the broader spectrum of telomere biology disorders (TBD). Coats plus syndrome has so far been associated with pathogenic variants in POT1, CTC1, and STN1.

Clonal landscape and clinical outcomes of telomere biology disorders: somatic rescue and cancer mutations.

Telomere biology disorders (TBDs), caused by pathogenic germ line variants in telomere-related genes, present with multiorgan disease and a predisposition to cancer. Clonal hematopoiesis (CH) as a marker of cancer development and survival in TBDs is poorly understood. Here, we characterized the clonal landscape of a large cohort of 207 patients with TBD with a broad range of age and phenotype.

Factors Affecting Compliance and Visual Outcomes in Patients Receiving Intravitreal Bevacizumab Injections.

Background Vascular endothelial growth factor (VEGF) is a powerful mitogen for endothelial cells that promotes migration, proliferation, and tube formation necessary for the angiogenic development of new blood vessels. When VEGF increases significantly, it causes pathological angiogenesis and increased vascular permeability in eye conditions such as diabetic retinopathy (DR), age-related macular degeneration (AMD), and retinal vein occlusion (RVO). These disorders have become important global sources of morbidity and have a substantial financial impact not only on the medical community but also on the patients.
