Hyper-Cross-Linked Polymer-Derived Carbon-Coated Fe-Ni Alloy/CNT as a Bifunctional Electrocatalyst for Rechargeable Zinc-Air Batteries.

The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are considered to be the most important processes in metal-air batteries and regenerative fuel cell devices. Metal-organic polymers are attracting interest as promising precursors of advanced metal/carbon electrocatalysts because of their hierarchical porous structure along with the integrated metal-carbon framework. We developed carbon-coated CNTs with Ni/Fe and Cu/Fe as active sites.

Ionic-liquid-supported copper-promoted synthesis of 3,5-disubstituted-1,2,4-triazoles.

The synthesis of triazoles plays an important role in drug discovery research. 1,2,4-triazoles are considered significant scaffolds among several bioactive heterocycles due to their extensive use in the pharmaceutical and agrochemical sectors. Consequently, the importance of the synthesis of 1,2,4-triazoles a sustainable method has increased.

An Unusual Case Report of Duodenojejunal Flexure Tumor With a Systematic Review of the Literature.

The small intestine is the longest segment of the gastrointestinal (GI) tract, but cancers in the small intestine are infrequent. The duodenojejunal (DJ) flexure is an uncommon site for tumors, and those located in these sites are difficult to identify and manage properly. Their rarity, along with ambiguous symptoms that can be readily misattributed to milder conditions, results in a delayed diagnosis when the tumors have significantly advanced.

Data-driven discovery of associations between prescribed drugs and dementia risk: A systematic review.

Abstract: Recent clinical trials on slowing dementia progression have led to renewed focus on finding safer, more effective treatments. One approach to identify plausible candidates is to assess whether existing medications for other conditions may affect dementia risk. We conducted a systematic review to identify studies adopting a data-driven approach to investigate the association between a wide range of prescribed medications and dementia risk.

Fibrosarcomatous Dermatofibrosarcoma Protuberans With COL1A1-PDGFB Fusion in a 2-Year-Old Child: A Rare Occurrence With Spectrum of Histopathological Findings and Review of Literature.

Dermatofibrosarcoma protuberans (DFSP) is an intermediate-grade fibroblastic neoplasm commonly seen in young and middle-aged patients and rarely in pediatric patients. Fibrosarcomatous transformation is common in adults but extremely uncommon in children. Here, we present a case of a 2-year-old child who presented with a progressively enlarging subcutaneous mass in the knee.
