General description

Electrochemical oxidation of 3-methylpyridine (3-MP) at synthetic boron-doped diamond (BDD) thin film electrode has been investigated by cyclic voltammetry and bulk electrolysis. 3-Methylpyridine forms adduct with 2,6-dichloro-4-nitrophenol and the structure of adduct has been determined by X-ray diffraction.

Pathological retinal angiogenesis is a major cause of vision loss. Semaphorin 3A (Sema3A), a chemorepellent guidance protein, plays crucial roles in neural and vascular patterning. To identify its role in retinal neovascularization, we investigated its antiangiogenic effects. Human umbilical vein
