Tuberculous ureteric stricture

Ceylon Medical Journal, 2015
The management of a young woman with a ureteric stricture is a challenge to the urologist. Genitourinary tuberculosis can cause ureteric strictures, with minimal symptoms. Untreated, it can lead to impairment of renal function. Diagnosis of genitourinary tuberculosis may be delayed until histopathological assessment.

Magnetically‐Induced Suppression of Oxidative Stress Prevents Venous Thrombosis

Advanced Science, EarlyView.
Venous thromboembolism (VTE) remains a leading cause of cardiovascular mortality. This study demonstrates that static magnetic fields (SMF) offer a novel non‐pharmacological intervention against VTE by mitigating endothelial oxidative stress. Mechanistically, SMF elevates intracellular Ca2+, boosts ATP production, and suppresses NOX4‐mediated ROS ...

The Utility of Magnetic Resonance Enterography and Double Balloon Enteroscopy-Assisted Endoscopic Balloon Dilatation for Small Bowel Strictures in Crohn’s Disease: A Retrospective Observational Study

Inflammatory Intestinal Diseases
Introduction: Crohn’s disease (CD) of the small bowel is associated with a severe course and increased risk of complications. Strictures at this location are challenging to diagnose and out-of-reach of colonoscopy. We aimed to evaluate the detection rate

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

Advanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

Monocyte‐Differentiation‐Activated Fluorescent “Scout” Probe for Precise in Vivo Detection of Vulnerable Plaque

Advanced Science, EarlyView.
An innovative monocyte‐differentiation‐activated fluorescent “scout” probe (MDAF) leverages the inherent chemotaxis of monocytes toward vulnerable plaques (VAP) to enable efficient targeted delivery while achieving spatiotemporally controllable activation of its AIE fluorescent signals with the dynamic differentiation of monocytes, providing an ...
