A Pilot Rapid Triage Process for Prehospital ST-Segment Myocardial Infarction Patients Direct to the Catheterization Lab.

Background Rapid treatment of ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention (PCI) significantly reduces morbidity and mortality rates. Recent studies emphasize the importance of reducing total ischemic time, making first-medical-contact-to-balloon (FMCTB) time a key performance indicator. To improve FMCTB times in patients brought to the Emergency Department (ED) by Emergency Medical Services (EMS), we implemented a "Direct to Lab" (DTL) workflow during the following conditions: weekday daytime hours, when the lab is fully staffed, and for hemodynamically stable STEMI patients presenting via EMS.

Vulvar Lactating Adenoma: A Rare Representation of Mammary-Like Anogenital Glands.

Mammary-like anogenital glands are considered a normal constituent of the anogenital area. These glands can have epithelial components with eccrine or apocrine features. They often undergo transformation into mammary-like lesions, including lactational changes that occur during pregnancy and the breastfeeding period.

The abscopal effects of sonodynamic therapy in cancer.

The abscopal effect is a phenomenon wherein localised therapy on the primary tumour leads to regression of distal metastatic growths. Interestingly, various pre-clinical studies utilising sonodynamic therapy (SDT) have reported significant abscopal effects, however, the mechanism remains largely enigmatic. SDT is an emerging non-invasive cancer treatment that uses focussed ultrasound (FUS) and a sonosensitiser to induce tumour cell death.

Treatment with novel topoisomerase inhibitors in Ewing sarcoma models reveals heterogeneity of tumor response.

Introduction: The topoisomerase 1 (TOP1) inhibitor irinotecan is a standard-of-care agent for relapsed Ewing sarcoma (EWS), but its efficacy is limited by chemical instability, rapid clearance and reversibility, and dose-limiting toxicities, such as diarrhea. Indenoisoquinolines (IIQs) represent a new class of clinical TOP1 inhibitors designed to address these limitations.

Methods: In this study, we evaluated the preclinical efficacy of three IIQs (LMP400, LMP744, and LMP776) in relevant models of EWS.

Understanding Glucagon Aggregation: In Silico Insights and Experimental Validation.

Peptide aggregation poses a significant challenge in biopharmaceutical development and neurodegenerative diseases. This study combines computational simulations and experimental validation to uncover the underlying mechanisms and countermeasures for the aggregation of glucagon, a peptide with a high tendency to aggregate. In silico simulations demonstrate that lactose and 2-hydroxypropyl-β-cyclodextrin (2-HPβCD) influence glucagon aggregation differently: lactose stabilizes glucagon by increasing the α-helical content, while 2-HPβCD disrupts protein-protein interactions.
