Engineering a defect-rich Prussian blue analog composite for enhanced Cs removal performance.

Using a novel, irregular honeycombed N-doped porous carbon (NPC) as a support and defect inducer, defect-rich Zn-PBA was formed and evenly anchored on the surface of NPC to obtain a defect-rich Zn-PBA/NPC composite. This composite demonstrated an ultrafast Cs adsorption rate that reached equilibrium within 60 s as well as excellent adsorption capacity, stability and reusability. The adsorption mechanism indicated that Cs was quickly adsorbed the defect sites close to the Zn-PBA crystal face accompanied by K(OH) elimination.

Rice body synovitis in systemic lupus erythematosus.

Rice bodies (RBs) synovitis in the shoulder joints of systemic lupus erythematosus patients is a rare clinical condition that has not been previously reported. Despite the fact that the diagnosis of RBs synovitis has primarily relied on MRI imaging, ultrasound has been used less frequently. In this report, we discuss a 43-year-old female diagnosed with systemic lupus erythematosus who presented with pain and swelling in the right shoulder.

This study aimed to investigate the protective effect and possible mechanisms of MgIG against cisplatin-induced nephrotoxicity from the perspective of cellular pharmacokinetics.

Species Difference in the Metabolism of Mulberrin in Vitro and Its Inhibitory Effect on Cytochrome P450 and UDP-Glucuronosyltransferase Enzymes.

This study aimed to evaluate the interspecies difference in metabolism of mulberrin and examine the interaction between mulberrin and CYP enzymes or recombinant human uridine 5'-diphosphate (UDP)-glucuronosyltransferase (UGT) enzymes. Liver microsomes from human (HLMs), Beagle dog (DLMs), minipig (PLMs), monkey (MLMs), rabbit (RLMs), rat (RAMs), and mouse (MIMs) were used to investigate metabolic diversity among different species. Additionally, recombinant human supersomes were used to confirm that metabolic enzymes are involved in the biotransformation of mulberrin.

Sex differences in cognitive flexibility are driven by the estrous cycle and stress-dependent.

Stress is associated with psychiatric disorders such as post-traumatic stress disorder, major depressive disorder, anxiety disorders, and panic disorders. Women are more likely to be diagnosed with these stress-related psychiatric disorders than men. A key phenotype in stress-related psychiatric disorders is impairment in cognitive flexibility, which is the ability to develop new strategies to respond to different patterns in the environment.

Developing effective adsorbents for Cs removal from complex wastewater systems has been a significant challenge. Although existing spheres adsorbents could improve the post-separation ability and practical operability, the adsorption kinetics are still significantly retarded due to the large intra-particle diffusion resistance. Here, we demonstrate the efficiency of a robust Prussian blue analogue/polyvinyl chloride composite membrane (PPM), which was easily prepared by a simple solvent evaporation method.
