Novel Design Strategy for Potent and Selective CDPK1 Inhibitors for Cryptosporidiosis
… a pyridopyrimidinone scaffold, was reported as a novel class of CDPK1 inhibitors showing good Cp growth inhibition (IC50 = 0.04 μM) in HCT-8 host cells and no acute toxicity in mice. However, UH15-16 also moderately inhibited human Src kinase (IC50 = 0.28 μM), which raises a toxicity concern. …

Finite Element Analysis of a Novel Design for a Non-Migrating Biliary Stent
Biliary stenting is most frequently caused by an interruption in the ability to drain bile into the duodenum. This obstructive jaundice is commonly a result of a stricture from a tumor located at the pancreas’s head, peri-ampulary area, bile duct, or gall bladder. Jaundice can also occur from …
