During the first weeks of life, injury to the central nervous system caused by brief periods of oxygen deprivation greatly increases. To investigate possible causes for this change, the effects of hypoxia or application of the excitatory neurotransmitter glutamate on intracellular calcium ([Ca2+]i) and ATP were studied in rat cerebrocortical brain slices.(More)
Recent studies suggest that turtles avoid disturbances in brain ionic regulation during anoxia by reducing the activity of brain calcium and sodium channels. Because glutamate released during anoxia may cause cytotoxic elevations in intracellular calcium, blockade of glutamate-mediated calcium channels may be essential for cellular survival. Elevations in(More)
In shaded wheat (Triticum aestivum L.) leaves, the suppression of blue radiation (BR) triggers senescence. This phenomenon is correlated to an increase in oxidative stress symptoms and a decrease of catalase (CAT) activity, among other traits. Previous data suggest that the radiation signal transduction pathway may involve changes in Ca2+ and H2O2(More)
