Discovery of a Pyrazolopyridinone-Based MYC Inhibitor That Selectively Engages Intracellular c-MYC and Disrupts MYC-MAX Heterodimerization.

c-MYC is an oncogenic transcription factor that plays a crucial role in the regulation of downstream targets involved in proliferation, apoptosis, differentiation, metabolism, signaling, and immune response processes whose deregulation leads to the progression of different pathologies. The development of selective and potent small-molecule inhibitors of c-MYC remains a grand challenge in chemical biology and medicine due to its undruggability, derived from extensive intrinsic disorder. In this study, we identified a novel dihydro pyrazolo pyridinone scaffold, , that selectively targets c-MYC in cells and disrupts MYC-MAX interaction.

Efficacy of Anthelmintics Against Canine Hookworm Infections in the Bono East Region of Ghana.

Hookworm infections present a major health risk to dogs, especially in areas characterized by warmer climates and poor sanitation. This cross-sectional study was undertaken to determine the prevalence of hookworm infections and the efficacy of anthelmintic treatments in dogs from the Bono East Region of Ghana. Four hundred and ninety-one (491) canine stool samples were examined using the McMaster technique to ascertain the prevalence of hookworms.

An activation-based high throughput screen identifies caspase-10 inhibitors.

Caspases are a family of highly homologous cysteine proteases that play critical roles in inflammation and apoptosis. Small molecule inhibitors are useful tools for studying caspase biology, complementary to genetic approaches. However, achieving inhibitor selectivity for individual members of this highly homologous enzyme family remains a major challenge in developing such tool compounds.

Management of Patients with Myocardial Injury After Noncardiac Surgery: A Retrospective Chart Review.

Background: Myocardial injury after noncardiac surgery (MINS) is associated with an increased incidence of cardiac morbidity and mortality. Little is known about how these patients are managed.

Methods: We performed a single-centre retrospective chart review of patients referred to a postoperative clinic with the diagnosis of MINS.

Safety and Efficacy of Tranexamic Acid in General Surgery.

Importance: Perioperative bleeding is common in general surgery. The POISE-3 (Perioperative Ischemic Evaluation-3) trial demonstrated efficacy of prophylactic tranexamic acid (TXA) compared with placebo in preventing major bleeding without increasing vascular outcomes in noncardiac surgery.

Objective: To determine the safety and efficacy of prophylactic TXA, specifically in general surgery.
