A novel ENTH domain-containing protein TgTEPSIN is essential for structural maintenance of the plant-like vacuolar compartment and bradyzoite differentiation in toxoplasma gondii.

Toxoplasma gondii is an intracellular and parasitic protozoon that harbors specialized cellular structures and molecular mechanisms, including the Plant-like Vacuolar Compartment (PLVAC). The PLVAC performs multifaceted roles in the parasite, contributing to ion homeostasis, proteolysis, pH regulation, and autophagy. Despite significant efforts over the past decade to characterize the PLVAC, the proteins localized to this organelle remain largely unidentified.

Discovery of Novel Diagnostic Biomarkers for Common Pathogenic Through Pan-Genome and Comparative Genome Analysis, with Preliminary Validation.

The aim of this study was to reveal diagnostic biomarkers of considerable importance for common pathogenic , utilizing pan-genomic and comparative genome analysis to accurately characterize clinical infections. In this study, complete or assembled genome sequences of common pathogenic and closely related species were obtained from NCBI as discovery and validation sets, respectively. Genome annotation was performed using Prokka software, and pan-genomic analysis and extraction of core genes were performed using BPGA software.

Bamboo-inspired ultra-strong nanofiber-reinforced composite hydrogels.

Biological materials, such as bamboo, are naturally optimized composites with exceptional mechanical properties. Inspired by such natural composites, traditional methods involve extracting nanofibers from natural sources and applying them in composite materials, which, however, often results in less ideal mechanical properties. To address this, this study develops a bottom-up nanofiber assembly strategy to create strong fiber-reinforced composite hydrogels inspired by the hierarchical assembly of bamboo.

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.
