Branched-chain amino acids levels associated with risk of erectile dysfunction: A Mendelian randomization analysis.

Background: Erectile dysfunction (ED) is a prevalent male sexual dysfunction that remarkably impacts patients' quality of life and is also recognized as a precursor to cardiovascular disease (CVD) events. Branched-chain amino acids (BCAAs) are derived from dietary intake and mainly involved in energy metabolism. Previous studies have underscored the association between BCAAs and CVD, but the causal link between BCAAs and ED remains uncertain.

Single-cell RNA sequencing reveals the changes of the pulmonary immune environment in rat after L. treatment.

FGF19-Activated Hepatic Stellate Cells Release ANGPTL4 that Promotes Colorectal Cancer Liver Metastasis.

Liver and lung are the most common metastatic sites in colorectal cancer (CRC), where the tumor microenvironment (TME) plays a crucial role in the progression and metastasis of CRC. Understanding the interactions between various types of cells in the TME can suggest innovative therapeutic strategies. Using single-cell RNA sequencing (scRNA-Seq) and clinical samples, fibroblast growth factor-19 (FGF19, rodent FGF15) is found to mediate a significant interaction between CRC cells and cancer-associated fibroblasts (CAFs), activating the hepatic stellate cells (HSCs)-to-CAFs differentiation.

Localized release of muscle-generated BDNF regulates the initial formation of postsynaptic apparatus at neuromuscular synapses.

Growing evidence indicates that brain-derived neurotrophic factor (BDNF) is produced in contracting skeletal muscles and is secreted as a myokine that plays an important role in muscle metabolism. However, the involvement of muscle-generated BDNF and the regulation of its vesicular trafficking, localization, proteolytic processing, and spatially restricted release during the development of vertebrate neuromuscular junctions (NMJs) remain largely unknown. In this study, we first reported that BDNF is spatially associated with the actin-rich core domain of podosome-like structures (PLSs) at topologically complex acetylcholine receptor (AChR) clusters in cultured Xenopus muscle cells.

Re-expansion pulmonary oedema: two case reports and review of the current literature.

Re-expansion pulmonary oedema (RPE) is an uncommon complication that occurs when a collapsed lung suddenly re-expands, resulting in an osmotic shift of fluid from the blood vessels into the air spaces within the lungs. This condition can develop following thoracocentesis or intercostal chest drainage. We report two cases of RPE that developed after varying volumes of pleural drainage and at different times.
