IQUB mutation induces radial spoke 1 deficiency causing asthenozoospermia with normal sperm morphology in humans and mice.

Background: Asthenozoospermia (ASZ) accounts for about 20-40% of male infertility, and genetic factors, contributing to 30-40% of the causes of ASZ, still need further exploration. Radial spokes (RSs), a T-shaped macromolecular complex, connect the peripheral doublet microtubules (DMTs) to a central pair (CP), forming a CP-RS-DMT structure to regulate the beat frequency and amplitude of sperm flagella. To date, many components of RSs and their functions in human sperm flagella remain unclear.

Safety and efficacy of catheter ablation in atrial fibrillation patients with heart failure with preserved ejection fraction.

Purpose: Catheter ablation (CA) for atrial fibrillation (AF) in heart failure patients with preserved ejection fraction (HFPEF) has shown promising results in reducing mortality and improving heart function. However, previous studies have been limited by a lack of control groups and significant heterogeneity in their methodologies.

Hypothesis: CA for AF in HFPEF patients may not increase the complications and had similarly the rate of freedom from AF vs.

Trichinella spiralis excretory/secretory proteins mediated larval invasion via inducing gut epithelial apoptosis and barrier disruption.

Background: Intestinal larva invasion is a crucial step of Trichinella spiralis infection. Intestinal infective larvae (IIL) and their excretory/secretory proteins (ESP) interact with gut epithelium, which often results in gut epithelium barrier injuries. Previous studies showed when T.

Vaccination of mice with Trichinella spiralis C-type lectin elicited the protective immunity and enhanced gut epithelial barrier function.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.
