introduction babesiosis is caused by apicomplexa parasites of the genus babesia. humans are commonly infected by babesia through tick bites. there is limited information available about babesia infection of humans in china. the aim of this study was to isolate the pathogen from a patient with severe parasitemia. case presentation blood samples were observed by transmission electron microscopy (...

Our objective was to study the properties of the carboxyfluorescein diacetate succinimidyl ester (CFDA-SE) and the methodology of cell labeling using CFDA-SE fluorescent dye. First, we analyzed the kinetics of CFDA-SE fluorescent dye intensity over time. Second, we determined the optimal concentration of CFDA-SE fluorescent dye for cell labeling. Third, we tested the toxicity of CFDA-SE fluores...

FluoSpheres and TransFluoSpheres polystyrene microspheres 1 satisfy several prerequisites of ideal long-term biological tracers. Because the dyes in our microspheres are incorporated throughout the microsphere rather than just on its surface, the fluorescence output per microsphere is significantly greater than that obtained from protein or dextran conjugates (Table 6.6) and is relatively immun...

let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
