Genome-wide comparative analyses highlight selection signatures underlying saline adaptation in Chilika buffalo.

Chilika, a native buffalo breed of the Eastern coast of India, is mainly distributed around the Chilika brackish water lake connected with the Bay of Bengal Sea. This breed possesses a unique ability to delve deep into the salty water of the lake and stay there to feed on local vegetation of saline nature. Adaptation to salinity is a genetic phenomenon; however, the genetic basis underlying salinity tolerance is still limited in animals, specifically in livestock.

Eco-evolutionary impact of ultraviolet radiation (UVR) exposure on microorganisms, with a special focus on our skin microbiome.

Sunlight is pivotal for our survival, and daily UV exposure has impacted the evolutionary course of all forms of life, from microorganisms to humans. Deciphering the role of UVR in regulating the microbial dynamics of environmental and host-associated microbes is crucial. UVR may be responsible for affecting skin pathology by influencing the skin microbiome, both qualitatively and quantitatively, as evident in low-dose narrow-band UVB phototherapy.

The PBMCs model was used for this investigation as it plays crucial role in the immune system regulation.

Genomic Diversity Profiling and Breed-Specific Evolutionary Signatures of Selection in Arunachali Yak.

Arunachali yak, the only registered yak breed of India, is crucial for the economic sustainability of pastoralist Monpa community. This study intended to determine the genomic diversity and to identify signatures of selection in the breed. Previously available double digest restriction-site associated DNA (ddRAD) sequencing data of Arunachali yak animals was processed and 99,919 SNPs were considered for further analysis.

Bacteriophage therapeutics to confront multidrug-resistant Acinetobacter baumannii - a global health menace.

We have already entered the post-antibiotic era as the outbreaks of numerous multidrug-resistant strains in the community as well as hospital-acquired infections are ringing alarm bells in the health sector. Acinetobacter baumannii is one such pathogen that has been considered a worldwide threat as it acquires multidrug resistance. It is one of the most challenging hospital-acquired pathogens as World Health Organization has listed carbapenem-resistant A.

Differentially expressed microRNAs in biochemically characterized Frieswal crossbred bull semen.

Validation of selected miRNAs viz.

Microbial, environmental and anthropogenic factors influencing the indoor microbiome of the built environment.

A built environment is a human-made environment providing surroundings for human occupancy, activities, and settlement. It is supposed to safeguard humans from all undesirable and harmful pollutants; however, indoor concentrations of some pollutants are much greater than that of the outdoors. Bioaerosols infiltrate from the outdoors in addition to many indoor sources of bioaerosols including the use of various chemicals as well as activities like cooking, smoking, cleaning, or even normal movement.

Comparison of Mental Health Status of Married and Unmarried Girls of Late Adolescent Age in an Urban Slum of Delhi.

Introduction: Late adolescence age (16-19 years) is organized around central task of achieving an identity. In India, age at marriage for girls has been legally declared as 18 years, but many girls are married much before this age. Early marriage for girls can have profound psychological and emotional impacts.

Genome-Wide Analysis to Identify HLA Factors Potentially Associated With Severe Dengue.

The pathogenesis of dengue hemorrhagic fever (DHF), following dengue virus (DENV) infection, is a complex and poorly understood phenomenon. In view of the clinical need of identifying patients with higher likelihood of developing this severe outcome, we undertook a comparative genome-wide association analysis of epitope variants from sequences available in the ViPR database that have been reported to be differentially related to dengue fever and DHF. Having enumerated the incriminated epitope variants, we determined the corresponding HLA alleles in the context of which DENV infection could potentially precipitate DHF.
