We report here fast A-site cation cross-exchange between APbX 3 perovskite nanocrystals (NCs) made of different A-cations (Cs (Cesium), FA (formamidinium), and MA (methylammonium)) at room temperature. Surprisingly, the A-cation proceeds as halide (X=Cl, Br, or I) exchange with help free A-oleate complexes present in freshly prepared colloidal NC solutions. It enabled preparation double (MACs, ...

An experiment was conducted to determine whether feeding rumen-protected fatty acids (FA) to postpartum heifers would increase plasma concentrations of linoleic acid and PGF2α metabolite (PGFM), shorten the interval from calving to first increase in plasma concentrations of progesterone (P4), and increase pregnancy rate relative to controls. Hereford × Angus heifers (346 kg) were assigned rando...

Leukocytosis and thrombocytopenia occur during cardiopulmonary bypass (CPB) with extracorporeal circulation (ECC). Elevated circulating concentrations of macrophage colony-stimulating factor (M-CSF) are reported during thrombocytopenia and leukopenia of different origins. We have assessed M-CSF concentrations in 40 patients undergoing CPB with ECC. Plasma M-CSF concentrations were stable during...

Background: Real-time monitoring of chronic lymphocytic leukemia (CLL) is crucial for effective patient management. Peripheral blood (PB) the preferred source obtaining CLL cells due to its ease access and lower cost. However, traditional methods evaluating PB films have several drawbacks, such as lack automation, reliance on personal experience, low repeatability reproducibility. To address th...
