Intestinal schistosomiasis masquerading as intestinal polyps.

Background: Schistosomiasis is very common in the southern part of the Yangtze River Basin in China. It is mainly manifested as appendicitis, ulcers, hematomas, and thickening of the intestinal tract. Schistosomiasis of the appendix is rare, mainly manifested as appendicitis, which is easy to be misdiagnosed.

Ce-Doping to Modulate Photoluminescence Kinetics for Efficient CsPbBr Nanocrystals Based Light-Emitting Diodes.

Inorganic perovskite CsPbBr nanocrystals (NCs) are emerging, highly attractive light emitters with high color purity and good thermal stability for light-emitting diodes (LEDs). Their high photo/electroluminescence efficiencies are very important for fabricating efficient LEDs. Here, we propose a novel strategy to enhance the photo/electroluminescence efficiency of CsPbBr NCs through doping of heterovalent Ce ions via a facile hot-injection method.

Large improvement of coercivity in Sm-(Co,Cu)/Fe films by Cu addition.

The magnetic properties and microstructure of Sm-(Co,Cu)/Fe films were investigated systematically. The addition of Cu is helpful for keeping a better multilayer structure due to the reduction of the crystallization temperature of the hard phase. With lowering the temperature, the coercivity of the Sm-(Co,Cu)/Fe films increases rapidly with a linear relationship.
