Organic phosphate pesticides are of great enviro-nmental concern primarily because they are toxic to mammals and birds, and are relatively soluble in water to contaminate surface water and groundwater [1,2]. In this study, the decomposition of phorate, a widely used organic phosphate insecticide, in aqueous solutions by Boron doped diamond(BDD) electrode was examined. The LD50 of phorate was re...

Synaptic NMDA receptors (NMDARs) are crucial for neural coding and plasticity. However, little is known about the adaptive function of extrasynaptic NMDARs occurring mainly on dendritic shafts. Here, we find that in CA1 pyramidal neurons, back-propagating action potentials (bAPs) recruit shaft NMDARs exposed to ambient glutamate. In contrast, spine NMDARs are "protected," under baseline conditi...

Bessey et al. (1) reported a simple method of photolytic determination of vitamin A in as little as 0.06ml of blood serum and Jackson et al. (2) and Krause et al. (3) used this method for studies on serum vitamin A. Sahashi et al. (4) reexamined the method applying the apparatus and reagents available in the country. Sobel et al. (5) noticed too high values for carotene, when the method was app...

A systematic consistency analysis and optimization procedure is applied to models of representative ozone, OH, and HO2 observations in the mesosphere and upper stratosphere. The approach considers both measurement and rate parameter uncertainties. The results show some data point inconsistencies and the inability of the accepted photochemical mechanism to predict observations without unfavored ...
