CD44-Mediated Metabolic Rewiring is A Targetable Dependency of IDH-Mutant Leukemia.

Recurrent IDH mutations catalyze NADPH-dependent production of oncometabolite R-2HG for tumorigenesis. IDH inhibition provides clinical response in a subset of acute myeloid leukemia (AML) cases; however, most patients develop resistance, highlighting the need for more effective IDH-targeting therapies. By comparing transcriptomic alterations in isogenic leukemia cells harboring CRISPR base-edited IDH mutations, we identify the activation of adhesion molecules including CD44, a transmembrane glycoprotein, as a shared feature of IDH-mutant leukemia, consistent with elevated CD44 expression in IDH-mutant AML patients.

Framing a Global Pandemic: Journalism Cultures and Media Coverage of COVID-19 in China, South Korea, the United Kingdom, and the United States.

Using a computational approach, this study analyzes and compares news coverage of the novel coronavirus in six major newspapers (i.e. , , , , , and ) from four countries (i.

Group a remains viable inside fibrin clots and gains access to human plasminogen for subsequent fibrinolysis and dissemination.

Unlabelled: Group A (GAS) is a major human pathogen that causes several invasive diseases including necrotizing fasciitis. The host coagulation cascade initiates fibrin clots to sequester bacteria to prevent dissemination into deeper tissues. GAS, especially skin-tropic bacterial strains, utilize specific virulence factors, plasminogen binding M-protein (PAM) and streptokinase (SK), to manipulate hemostasis and activate plasminogen to cause fibrinolysis and fibrin clot escape.

The Role of Re-Entrant Microstructures in Modulating Droplet Evaporation Modes.

The evaporation dynamics of sessile droplets on re-entrant microstructures are critical for applications in microfluidics, thermal management, and self-cleaning surfaces. Re-entrant structures, such as mushroom-like shapes with overhanging features, trap air beneath droplets to enhance non-wettability. The present study examines the evaporation of a water droplet on silicon carbide (SiC) and silicon dioxide (SiO) re-entrant structures, focusing on the effects of material composition and solid area fraction on volume reduction, contact angle, and evaporation modes.

The GLOB-cAGE Consortium: A Global Cardiovascular Collaborative Network of Older Adults with Cardiovascular Disease.

Background: GLOB-cAGE is a newly established unprecedented consortium that brings together cohorts of older persons with cardiovascular disease worldwide. GLOB-cAGE aims to harmonize non-identifiable data from longitudinal cohorts examining cardiovascular health and cardiovascular disease diagnosis and management in older individuals to perform meta-regression analyses using combined repositories of standardized subject-level data points.

Methods And Design: Studies registered into GLOB-cAGE are population-based longitudinal cohort studies or clinical trials, either ongoing or completed, that involve assessing cardiovascular health as a central objective.
