Infections caused by fungal pathogens are a global health problem, and have created an urgent need for new antimicrobial strategies. This report details the synthesis of lipidated 2-vinyl-4,4-dimethyl-5-oxazolone (VDM) oligomers an optimized Cu(0)-mediated reversible-deactivation radical polymerization (RDRP) approach. Cholesterol-Br was used as an initiator to synthesize a library of oligo-VDM (degree of polymerisation = 5, 10, 15, 20, and 25), with an α-terminal cholesterol group.

Introduction: Veno-venous extracorporeal membrane oxygenation (V-V ECMO) is increasingly used in the treatment of severe respiratory failure. Despite a significant increase in the worldwide use of extracorporeal lung assist devices recirculation remains a common complication and is associated with a reduced effectiveness of ECMO support and increased hemolysis. In this observational study we aimed to investigate the impact of cannula configuration and extracorporeal flow on recirculation.

The therapeutic effect of immune checkpoint inhibitors (ICIs) in triple-negative breast cancer (TNBC) is unsatisfactory. The immune "cold" microenvironment caused by tumor-associated fibroblasts (TAFs) has an adverse effect on the antitumor response. Therefore, in this study, mixed cell membrane-coated porous magnetic nanoparticles (PMNPs) were constructed to deliver salvianolic acid B (SAB) to induce an antitumor immune response, facilitating the transition from a "cold" to a "hot" tumor and ultimately enhancing the therapeutic efficacy of immune checkpoint inhibitors.

Background: EMP2 is a tumor-associated membrane protein belonging to the GAS-3/PMP22 gene family. EMP2 expression demonstrates significant tissue specificity and heterogeneity in various human tissues and tumor tissues, where it may play a role in either promoting or inhibiting tumor growth. This study aimed to investigate the expression level, biological functions, and molecular mechanisms of EMP2 in liver cancer.

Background: Currently, there is limited research on the impact of abdominal infection on intestinal damage under microgravity conditions. Cordyceps polysaccharide (CPS), the main active ingredient of Cordyceps, has demonstrated various pharmacological effects, including anti-inflammatory, antioxidant, and immunomodulatory properties. Moxifloxacin (MXF) is a fourth-generation quinolone antibiotic that is believed to have a dual regulatory effect on immune system activation and suppression.
