BACKGROUND Mifepristone (RU486), a potent antagonist of progesterone and glucocorticoids, is involved in immune regulation. Our previous studies demonstrated that mifepristone directly augments the cytotoxicity of human uterine natural killer (uNK) cells. However, the mechanism responsible for this increase in cytotoxicity is not known. Here, we explored whether the increased cytotoxicity in uN...

Many medicinal plants found in Africa, such as Dovyallis caffra, have been reported to contain various bioactive compounds, which reduce metal salts into their corresponding metal-based nanoparticles. In this paper, the evaluation of synthesis, characterization, and biological properties caffra-mediated cassiterite (SnO2) nanoparticles was carried out. The physicochemical synthesized material w...
