Identification of Ftr1 and Zrt1 as iron and zinc micronutrient transceptors for activation of the PKA pathway in Saccharomyces cerevisiae

Multiple types of nutrient transceptors, membrane proteins that combine a transporter and receptor function, have now been established in a variety of organisms.However, so far all established transceptors utilize one of the macronutrients, glucose, amino acids, ammonium, nitrate, phosphate or sulfate, as substrate.This is also true for the Sacchar

Effects of ionizing radiation on schedule-induced polydipsia

The aim of the present work was to explore and evaluate the effects of ionizing radiation on schedule-induced polydipsia.Five food deprived rats were used as subjects and submitted to baseline procedure, after that they were divided in two experimental groups: two subjects were exposed to a fixed-time 60 seconds of food schedule (FT 60 s) and three
