Expression and localization of HBsAg in corneas from HBsAgseropositive donors preserved in mediumterm preservation solution and glycerol.

Objectives: Due to the severe shortage of donor corneas for transplantation in China, corneal component transplantation may expand the available donor pool. This study aims to evaluate the safety and feasibility of corneal component transplantation by examining the distribution of hepatitis B surface antigen (HBsAg) in corneas from HBsAg-seropositive donors under different storage media.

Methods: Ten corneas (from 6 donors) donated between December 2019 and March 2021 and stored at the Eye Bank of Xiangya Third Hospital, Central South University, were analyzed.

Design Strategies of S Molecule Cathodes for Room-Temperature Na-S Batteries.

Sodium-sulfur batteries have been provided as a highly attractive solution for large-scale energy storage, benefiting from their substantial storage capacity, the abundance of raw materials, and cost-effectiveness. Nevertheless, conventional sodium-sulfur batteries have been the subject of critique due to their high operating temperature and costly maintenance. In contrast, room-temperature sodium-sulfur batteries exhibit significant advantages in these regards.

Population genomics and transcriptomics identify patterns of selection in two Liangshan chicken breeds.

1. The global diversity of domestic chicken breeds, each exhibiting unique and specialised traits, offers a compelling context to explore how selection influences genetic variation patterns. China, with its myriad local chicken breeds, contributes significantly to this diversity.

Methylseleninic Acid Elevating the Nrf2-GPX4 Axis Relieves Endothelial Dysfunction and Ferroptosis Induced by Arsenic Exposure.

Chronic exposure to arsenic (As), a ubiquitous contaminant, poses deleterious health risks to humans, including cardiovascular disease. Recent studies have implicated ferroptosis, in which the essential micronutrient selenium (Se) plays a crucial role, in several As-induced pathological processes. However, whether Se can counteract As-induced endothelial dysfunction through ferroptosis remains unclear.

Network analyses unraveled the complex interactions in the rumen microbiota associated with methane emission in dairy cattle.

Background: Methane emissions from livestock, particularly from dairy cattle, represent a significant source of greenhouse gas, contributing to the global climate crisis. Understanding the complex interactions within the rumen microbiota that influence methane emissions is crucial for developing effective mitigation strategies.

Results: This study employed Weighted Gene Co-expression Network Analysis to investigate the complex interactions within the rumen microbiota that influence methane emissions.
