Mapping the molecular mechanism of zinc catalyzed Suzuki-Miyaura coupling reaction: a computational study.

The Suzuki-Miyaura Coupling (SMC) reaction is a powerful method for forming carbon-carbon bonds in organic synthesis. Recent advancements in SMC reactions have introduced first-row transition metal catalysts, with zinc garnering significant interest due to its cost-effective and eco-friendly nature. Despite progress in experimental protocols, the mechanistic details of zinc-catalyzed SMC reactions are limited.

The Role of Processed Electroencephalography in the Detection and Management of Acute Cerebral Ischemia: A Scoping Review.

Processed electroencephalography (pEEG) is increasingly used to titrate the depth of anesthesia. Whether such intra-procedural pEEG monitoring can offer additional information on cerebral perfusion or acute focal or global cerebral ischemia is unknown. This scoping review aimed to provide a narrative analysis of the current literature reporting the potential role of pEEG in adults with acute cerebral ischemia.

Undifferentiated Pleomorphic Sarcoma: A Case Report.

Undifferentiated pleomorphic sarcoma (UPS) is an uncommon and aggressive soft tissue tumor primarily affecting older adults, often presenting as a rapidly enlarging, painless mass in the extremities or other deep-seated locations. This case involves a 55-year-old woman who experienced a rapidly progressive and painful swelling in her right thigh following trauma. Imaging studies identified a large, lobulated tumor in the adductor muscles, close to the femur and pubic ramus, with no bone involvement or evidence of distant metastasis.

Latitudinal gradients in air density create invisible topography at sea level, affecting animal flight costs.

Regional patterns in wind underpin the low-cost migratory flyways of billions of birds and insects, but the effect of large-scale changes in temperature on flight is unknown. Flight costs should increase with rising temperatures because lift decreases as density decreases, whereas weight remains unchanged. The effects of density are well-established in the context of high-altitude movements and migration.
