PTFE Stent Membrane Based on the Electrospinning Technique and Its Potential for Replacing ePTFE.

Expanded poly(tetrafluoroethylene) (ePTFE), obtained by the paste extrusion-stretching method, is a commonly used stent membrane material for the treatment of arterial stenosis or aneurysm in clinical practice. However, the structure of ePTFE is nonfibrous, which is not friendly to cells, and the equipment consumes a lot of energy and often requires the use of flammable and toxic lubricants. In this study, electrospinning was used to prepare PTFE vascular stent membranes, following plasma treatment, dopamine, and heparin grafting to obtain an anticoagulant surface.

Optimizing continuous passive motion duration following arthroscopic release of elbow contracture: a retrospective study.

The online software JASPAR was used to predict transcription factors binding to differentially methylated sites.

ICOSL deficiency promotes M1 polarization to alleviate liver fibrosis in schistosomiasis mice.

The expression of inducible co-stimulator ligand (ICOSL) on macrophage (Mφ) implies their ability to interact with inducible co-stimulator (ICOS)-expressing T cells, thereby modulating immune responses within the liver microenvironment. This study aimed to elucidate the mechanism underlying ICOS/ICOSL signaling in the regulation of Mφ polarization during Schistosomiasis-induced liver fibrosis. To investigate this, ICOSL-knock out (KO) and wildtype (WT) C57BL/6 mice were infected with Schistosoma japonicum (S.

The immune function of thioester-containing proteins in typical invertebrate disease vectors.

Disease vectors, such as arthropods, primarily rely on innate immunity to counteract pathogen invasions, typically through the recognition and binding of pathogen-associated molecular patterns (PAMPs) by the host's pattern recognition receptors (PRRs). As a conserved immune effector gene family from insects to mammals, the complement system may play an essential role in combating pathogenic microorganisms. In arthropods, the complement proteins are often referred to as thioester-containing proteins (TEPs) because thioester motifs are one of the essential functional domains of the first proteins characterized within the C3 and AM family.

Carbon dots induce endoplasmic reticulum stress-mediated lipid dysregulation and embryonic developmental toxicity in zebrafish.

Carbon dots (CDs) are widely utilized due to their exceptional physical and chemical properties. Nevertheless, there is a paucity of research examining the potential toxicity of carbon dots to human health, particularly with regard to developmental toxicity. The present study demonstrated that exposure to CDs resulted in increased mortality and malformations in zebrafish embryos.

Investigating the diagnostic and prognostic significance of genes related to fatty acid metabolism in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal cancers worldwide, with death rates increasing by approximately 2-3% per year. The high mortality and poor prognosis of HCC are primarily due to inaccurate early diagnosis and lack of monitoring when liver transplantation is not feasible. Fatty acid (FA) metabolism is a critical metabolic pathway that provides energy and signaling factors in cancer, particularly in HCC, and promotes malignancy.

GelMA encapsulating BMSCs-exosomes combined with interference screw or suture anchor promotes tendon-bone healing in a rabbit model.

The tendon-bone junction (TBJ), a critical transitional zone where tendons and bones connect, is particularly prone to injury due to the forces from muscle contractions and skeletal movements. Once tendon-bone injuries occur, the complex original tissue structure is difficult to restore, increasing the risk of re-tear. In this study, we initially established a rabbit model of tendon-bone injury and treated it using either interference screw or suture anchor.
