Assessment of age specific serum Prostate Specific Antigen (PSA) levels for Indian population: A retrospective analysis at a tertiary healthcare facility.

Introduction: Prostate-specific antigen (PSA) is a key marker for prostate cancer screening, but its utility is debated, prompting exploration of PSA derivatives for improved accuracy. While racial variations in serum PSA levels are documented, limited data exists for the Indian population. Given increasing life expectancy and heightened awareness of prostate cancer, this study aims to establish age-specific PSA ranges in an Indian cohort, contributing vital insights for population-specific screening and diagnosis.

Laccase Immobilized on Arginine-Functionalized Boron Nitride Nanosheets for Enhanced Atrazine Degradation.

Enzyme-mediated systems have been widely employed for the biotransformation of environmental contaminants. However, the catalytic performance of free enzymes is restricted by the rapid loss of their catalytic activity, stability, and reusability. In this work, we developed an enzyme immobilization platform by elaborately anchoring fungal laccase onto arginine-functionalized boron nitride nanosheets (BNNS-Arg@Lac).

Developing a microbial community structure index (MCSI) as an approach to evaluate and optimize bioremediation performance.

Much attention is placed on organohalide-respiring bacteria (OHRB), such as Dehalococcoides, during the design and performance monitoring of chlorinated solvent bioremediation systems. However, many OHRB cannot function effectively without the support of a diverse group of other microbial community members (MCMs), who play key roles fermenting organic matter into more readily useable electron donors, producing corrinoids such as vitamin B12, or facilitating other important metabolic processes or biochemical reactions. While it is known that certain MCMs support dechlorination, a metric considering their contribution to bioremediation performance has yet to be proposed.

Evaluation of historical data on persistent organic pollutants and heavy metals in Lake Baikal: Implications for accumulation in marine environments.

Lake Baikal, the largest freshwater lake by volume, provides drinking water and aquatic food supplies to over 2.5 million people. However, the lake has been contaminated with recalcitrant pollutants released from surrounding industrial complexes, agriculture, and natural lands, thereby increasing the risk of their bioaccumulation in fish and seals.
