Solvothermal Synthesis of Medium-Entropy Oxide Spheres for Thermocatalytic Conversion of CO to Methanol.

New chemical compositions and structures for medium- and high-entropy oxides (HEOs) currently represent a promising new avenue in materials research for a wide range of applications including catalysis, energy storage, and ceramics. To speed up further development, synthesis methods for multicationic oxides are needed for controlling features like morphology, porosity, and chemical compositions. In this work, mesoporous spinel oxide spheres with five cations are synthesized using solvothermal synthesis techniques.

Bafilomycin 1A Affects p62/SQSTM1 Autophagy Marker Protein Level and Autophagosome Puncta Formation Oppositely under Various Inflammatory Conditions in Cultured Rat Microglial Cells.

Regulation of autophagy through the 62 kDa ubiquitin-binding protein/autophagosome cargo protein sequestosome 1 (p62/SQSTM1), whose level is generally inversely proportional to autophagy, is crucial in microglial functions. Since autophagy is involved in inflammatory mechanisms, we investigated the actions of pro-inflammatory lipopolysaccharide (LPS) and anti-inflammatory rosuvastatin (RST) in secondary microglial cultures with or without bafilomycin A1 (BAF) pretreatment, an antibiotic that potently inhibits autophagosome fusion with lysosomes. The levels of the microglia marker protein Iba1 and the autophagosome marker protein p62/SQSTM1 were quantified by Western blots, while the number of p62/SQSTM1 immunoreactive puncta was quantitatively analyzed using fluorescent immunocytochemistry.

Temperature Evolution of Composition, Thermal, Electrical and Magnetic Properties of TiCT-MXene.

MXenes are a family of two-dimensional nanomaterials. Titanium carbide MXene (TiCT-MXene), reported in 2011, is the first inorganic compound reported among the MXene family. In the present work, we report on the study of the composition and various physical properties of TiCT-MXene nanomaterial, as well as their temperature evolution, to consider MXenes for space applications.

Significantly Elevated CA 19-9 after COVID-19 Vaccination and Literature Review of Non-Cancerous Cases with CA 19-9 > 1000 U/mL.

Background: CA 19-9 is a commonly assessed tumor marker, considered characteristic of pancreatic ductal adenocarcinoma (PDAC) and biliary tract cancers; however, the positive predictive value of CA 19.9 is too low, and the usage of CA 19.9 as a screening tool in the healthy population remains controversial.
