Cell-cell crosstalk in the pathogenesis of acute lung injury and acute respiratory distress syndrome.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the result of an exaggerated inflammatory response triggered by a variety of pulmonary and systemic insults. The lung tissues are comprised of a variety of cell types, including alveolar epithelial cells, pulmonary vascular endothelial cells, macrophages, neutrophils, and others. There is mounting evidence that these diverse cell populations within the lung interact to regulate lung inflammation in response to both direct and indirect stimuli.

Identification and Construction of a R-loop Mediated Diagnostic Model and Associated Immune Microenvironment of COPD through Machine Learning and Single-Cell Transcriptomics.

However, the risk of minor stroke has been consistently higher with carotid artery stenting.

Objectives: The authors sought to evaluate the safety and effectiveness of a novel carotid stent system comprised of a stent, an adjustable integrated embolic filter and a postdilation balloon, in patients at elevated risk for adverse events from carotid endarterectomy.

Extensive homologous recombination safeguards oocyte genome integrity in mammals.

Meiosis in mammalian oocytes is interrupted by a prolonged arrest at the germinal vesicle stage, during which oocytes have to repair DNA lesions to ensure genome integrity or otherwise undergo apoptosis. The FIRRM/FLIP-FIGNL1 complex dissociates RAD51 from the joint DNA molecules in both homologous recombination (HR) and DNA replication. However, as a type of non-meiotic, non-replicative cells, whether this RAD51-dismantling mechanism regulates genome integrity in oocytes remains elusive.

Effects of Exogenous Boron on Salt Stress Responses of Three Mangrove Species.

Salt stress is common but detrimental to plant growth, even in mangroves that live in saline areas. Boron (B) is an essential micronutrient that performs an important role in many functions in plants; however, its protective role under salt stress is poorly understood, especially in long-lived woody plants. In this study, we conducted an indoor experiment under simulated tidal conditions with four treatments (10‱ salinity, 40‱ salinity, 40‱ salinity + 100 μM B, and 40‱ salinity + 500 μM B) and three mangrove species (, , and ) to investigate the effects of exogenous B on salt tolerance in plant growth, morphology, physiology, and leaf anatomy.
