Recovery of Complex Isolates Including Pre-Extensively Drug-Resistant Strains From Cattle at a Slaughterhouse in Chennai, India.

Background: India has the highest global burden of human tuberculosis (TB) and the largest cattle herd with endemic bovine TB (bTB). However, the extent of cross-species transmission and the zoonotic spillover risk, including drug-resistant complex (MTBC) strains circulating in cattle, remain uncharacterized.

Methods: To address this major knowledge gap, we investigated tissue samples from 500 apparently healthy cattle at a slaughterhouse in Chennai, India.

Host-Matrix Interactions and Molecular Functionalization: Shaping the Delayed Emission Properties of Indenophenanthridine Derivatives.

The advancement of organic room temperature phosphorescence (RTP) materials has attracted considerable interest owing to their extensive applications. Their distinct advantages, including a metal-free composition, low toxicity, and facile synthesis under ambient conditions, make them highly desirable. This study examines the delayed fluorescence (DF) and RTP of metal-free, amorphous indenophenanthridine (IND)-based derivatives (1-10) and provides insights into molecular functionalisation and host matrix effects on delayed emission (RTP and DF).

Accurate Molar Mass Estimation of Polyolefin Blends Using High Temperature-size Exclusion Chromatography With Triple Detection: Insight Into Molecular Level Mixing of Polypropylene With Various Application Grades of Polyethylene.

In this study, a commercially available polypropylene homopolymer (H-PP) was blended with blow molding polyethylene (PE) grade via melt mixing using a compounding machine. The resulting blends were subjected to high-temperature size exclusion chromatography (SEC) analysis, coupled with infrared-5 (IR-5), viscometer (VISCO), and multi-angle laser light scattering (MALS) detectors. The molecular weight (MW) and MW distributions were investigated using SEC, and the exact blend compositions were evaluated using C nuclear magnetic resonance.

Impact of selenium supplementation on antioxidant enzyme activity and liver gene expression in juvenile pangasius catfish (Pangasius pangasius).

This study examined the effect of dietary selenium (Se) fortification on growth efficiency, antioxidant status, and liver gene expression in juvenile pangasius catfish. Sodium selenite was incorporated into a basal diet at incremental levels of 0-2.0 mg Se/kg.

Dysregulated genes in HIGK-treated and their possible association with HNSCC.

The present study aims to identify the differentially expressed genes in HIGK treated with and their possible role in establishing head and neck squamous cell carcinoma. The study design follows a computational approach wherein multiple databases and tools are used to derive the possible association between exposure and the development of HNSCC. The GEOmnibus dataset GSE6927 provided data on the differentially expressed genes in the HIGK treated with .
