A major role for Müller cells in the retina is to buffer changes in the extracellular K+ concentration ([K+]o) resulting from light-evoked neuronal activity. The primary K+ conductance in Müller cells is the inwardly rectifying K+ channel Kir4.1. Since this channel is constitutively active, K+ can enter or exit Müller cells depending on the state of the [K+]o. This process of [K+]o buffering by...

Nano dithiocarbamate (DTC) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. Reaction conditions such as the ligand DTC and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. The dithiocarbamate complex nanoparticles have been pre...

In order to assess the presence or absence of fluids under peak metamorphic conditions within the inner aureole of the Etive igneous complex in west Scotland, eight suitable metabasic hornfels samples and one suitable pelitic hornfels were used to calculate water activities using a mineral equilibria. Calculated activities for water are lower than unity in the pelitic sample and extremely low i...
