Introduction: Acute cholecystitis (AC) is a prevalent condition in emergency departments (EDs). Standard care involves early laparoscopic cholecystectomy; however, in cases of delayed presentation, high surgical risk, or during situations like the COVID-19 pandemic, percutaneous cholecystostomy (PC) serves as an alternative management strategy. This study reports our center's experience with PC in managing AC, providing insights from a unique geographical context.

All extracts and fractions showed antioxidant (DPPH and FRAP) and enzyme inhibition activities (HAS and DPP-IV) and also suppressed STZ-effects in diabetic mice by increasing Superoxide Dismutase, Glutathione S-Transferase and insulin and decreasing HOMA2-IR, urea and creatinine, with sumac extract showing benefits even when administered prior to STZ. These findings suggest that all tested extracts, particularly sumac, possess significant antioxidant and antidiabetic potential.

View Article and Find Full Text PDFThe timings of several cellular events like cell lysis, cell division, or pore formation in endosomes are regulated by the time taken for the relevant proteins to cross a threshold in number or concentration. Since protein synthesis is stochastic, the threshold crossing time is a first passage problem. The exact distributions of these first passage processes have been obtained recently for unregulated and autoregulated genes.

A key component in developing atrial digital twins (ADT) - virtual representations of patients' atria - is the accurate prescription of myocardial fibers which are essential for the tissue characterization. Due to the difficulty of reconstructing atrial fibers from medical imaging, a widely used strategy for fiber generation in ADT relies on mathematical models. Existing methodologies utilize semi-automatic approaches, are tailored to specific morphologies, and lack rigorous validation against imaging fiber data.
