Language control processes allow for the flexible manipulation and access to context-appropriate verbal representations. Functional magnetic resonance imaging (fMRI) studies have localized the brain regions involved in language control processes usually by comparing high vs. low lexical-semantic control conditions during verbal tasks.

Background: In modern conflicts, extremities are mainly affected, with limb amputations required for approximately 5% of severely injured combatants and 7% of those with serious limb injuries. Amputations are some of the most challenging injuries endured by survivors, significantly affecting the patients and the healthcare system. This study aims to describe the rates, characteristics, and risk factors of limb amputations in patients with serious extremity trauma during the 2023 conflict in Israel.

Increased expression of the stem cell transcription factor, MECOM, underlies one key driver mechanism in largely incurable AMLs. How MECOM results in such aggressive AML phenotypes remains unknown.

In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Methods: This single-center retrospective study evaluated consecutive patients undergoing ViV TAVR with the Evolut Pro/Pro+/Fx between 2018 and 2022. These patients were compared based on the true internal diameter (ID) of the failed bioprosthesis, specifically ≤19 mm (small group) vs.
