Study on the In Vitro and In Vivo Antioxidant Activity and Potential Mechanism of L.

Oxidative stress refers to the phenomenon in which the redox balance of the body is disrupted in response to stimuli, leading to an excessive accumulation of reactive oxygen species in vivo, which can lead to a variety of diseases. In contrast to artificial antioxidants, whose safety is controversial, natural antioxidants, which are widely available, pharmacologically active, and have little toxic side effects, are expected to be candidates for the treatment of oxidative stress-related diseases.

Lubricating Copolymer Brushes Achieving Excellent Antiadhesion and Antibacterial Performance through Hydration and Electrostatic Repulsion Effects.

Interventional catheters have been widely applied in diagnostics, therapeutics, and other biomedical areas. The complications caused by catheter-related bacterial infection, venous thrombosis, and vascular abrasion have become the main reasons for the failure of interventional therapy. In this study, polyacrylamide/poly(acrylic acid) lubricating copolymer brushes were constructed on the surface of catheters and efficiently resisted the adhesion of blood components and bacteria through hydration and electrostatic repulsion effects.

[Preoperative diagnostic efficacy of novel blood markers white blood cell ratio and fibrinogen levels in periprosthetic joint infection].

Objective: To investigate the clinical utility of novel of new hematological markers in the preoperative diagnosis of periprosthetic joint infection (PJI).

Methods: A retrospective analysis was conducted on a total of 149 patients who underwent revision of total hip arthroplasty (THA) or total knee arthroplasty (TKA) at a single center between January 2016 and June 2022, including 63 males and 86 females, aged from 47 to 93 years old with an average of (69.5±11.

Identification of germplasm resources based on metabolomics and DNA barcoding.

Introduction: radix et rhizoma (Danshen) is a crucial medicinal material for treating cardiovascular and cerebrovascular diseases. However, the presence of adulterants and intraspecific variability poses challenges to its clinical safety.

Methods: This study collected samples of from various regions and commonly encountered adulterants.

FSD1 inhibits glioblastoma diffuse infiltration through restriction of HDAC6-mediated microtubule deacetylation.

The infiltration of glioblastoma multiforme (GBM) is predominantly characterized by diffuse spread, contributing significantly to therapy resistance and recurrence of GBM. In this study, we reveal that microtubule deacetylation, mediated through the downregulation of fibronectin type III and SPRY domain-containing 1 (FSD1), plays a pivotal role in promoting GBM diffuse infiltration. FSD1 directly interacts with histone deacetylase 6 (HDAC6) at its second catalytic domain, thereby impeding its deacetylase activity on α-tubulin and preventing microtubule deacetylation and depolymerization.
