Biochem/physiol Actions

Potassium channel blocker. Antimalarial
Potassium channel blocker. Antimalarial, anticholinergic, antihypertensive, and hypoglycemic agent; alkaloid originally isolated from the Cinchona family of South American trees. Inhibits mitochondrial ATP-regulated potassium channel. Used to study the metabolism of biocrystalized heme, hemozoin, in malarial parasites and to study the toxicity of heme (FP)-complexes.

We have used magnetization transfer NMR experiments to measure the exchange rate constant (kex) of the imino protons in the unbound, cocaine-bound, and quinine-bound forms of the cocaine-binding DNA aptamer. Both long-stem 1 (MN4) and short-stem 1 (MN19) variants were

Coinfection can markedly alter the response to a pathogen, thereby changing its clinical presentation. For example, non-typhoidal Salmonella (NTS) serotypes are associated with gastroenteritis in immunocompetent individuals. In contrast, individuals with severe pediatric malaria can develop bacteremic infections with NTS

High production output of solid pharmaceutical formulations requires fast methods to ensure their quality. Likewise, fast analytical procedures are required in forensic sciences, for example at customs, to substantiate an initial suspicion. We here present the design and the optimization

New hybrid materials consisting of ZnO nanorods sensitized with three different biomass-derived carbon quantum dots (CQDs) were synthesized, characterized, and used for the first time to build solid-state nanostructured solar cells. The performance of the devices was dependent on the

Hollow cross-linked fluorescent carbon nitride nanoparticles (CNNPs) were fabricated via a facile one-pot solvothermal process. The obtained CNNPs were characterized by multiple analytical techniques including transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), solid-state nuclear magnetic resonance
