PROLONGED ROTE LEARNING PRODUCES DELAYED MEMORY FACILITATION AND METABOLIC CHANGES IN THE HIPPOCAMPUS OF THE AGEING HUMAN BRAIN

Prolonged rote learning produces delayed memory facilitation and metabolic changes in the hippocampus of the ageing human brain

Abstract Background Repeated rehearsal is one method by which verbal material may be transferred from short- to long-term memory.We hypothesised that extended engagement of memory structures through prolonged rehearsal would result orly purple nail polish in enhanced efficacy of recall and also of brain structures implicated in new learning.Twenty-

Formation of NifA-PII complex represses ammonium-sensitive nitrogen fixation in diazotrophic proteobacteria lacking NifL

Summary: Biological nitrogen fixation catalyzed by nitrogenase contributes greatly to the global nitrogen cycle.Nitrogenase expression is subject to regulation in response to nitrogen availability.However, the mechanism through which the vive night splint transcriptional activator NifA regulates nitrogenase expression by interacting with PII nitrog
