Generation of an electrochemical proton gradient is the first step of cell bioenergetics. In prokaryotes, the gradient is created by outward membrane protein proton pumps. Inward plasma membrane native proton pumps are yet unknown. We describe comprehensive functional studies of the representatives of the yet noncharacterized xenorhodopsins from Nanohaloarchaea family of microbial rhodopsins. T...

abstractintroduction: previous investigations have shown that protein malnutrition can alters the structure and function of some areas of hippocampal formation. we investigated the effect of protein malnutrition on amygdaloid projections to the ca1 hippocampal area. in this study we investigated level and pattern of distribution of efferent projections from amygdala to hippocampus in the rat by...

Bacterial meningitis causes persisting neurofunctional sequelae. Theoccurrence of apoptotic cell death in the hippocampal subgranular zone of the dentate gyrus characterizes the disease in patients and relates to deficits in learning and memory in corresponding experimental models. Here, we investigated why neurogenesis fails to regenerate the damage in the hippocampus associated with the persi...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

 Background and Objective: Based on both laboratory animal and human society studies, inequality in food intake and social instability has adverse effects on individuals and community health. However, it is not known whether social instability, food deprivation and food inequality affect neuronal death and premature aging in young animals. To address this question, the effect of food d...

This study investigated location-, movement-, and directional-selectivity of action potential discharges of hippocampal neurons in awake rats subjected to passive displacements in order to estimate vestibular contributions to this activity. Water-deprived rats were habituated to being restrained in a sling mounted on a moving robot. The extracellular activity of single complex-spike cells in ar...

Group I metabotropic glutamate (mGlu) receptors regulate hippocampal CA1 pyramidal neuron excitability via Ca(2+) wave-dependent activation of small-conductance Ca(2+)-activated K(+) (SK) channels. Here, we show that mGlu5 receptors and SK2 channels coassemble in heterologous coexpression systems and in rat brain. Further, in cotransfected cells or rat primary hippocampal neurons, mGlu5 recepto...

    Background & Aim: Maternal steroids modulate various functions in the brain. However, tamoxifen(TAM) treatment, as an estrogen antagonist, induces cell death in the hippocampus formation of a prenatal and postnatal rat. Estrogen influences cognitive functions, learning process, aging, vasodilation, angiogenesis, neurogenesis and neuroprotection. The present study deals with the effects of t...

Hippocampal neural stem/progenitor cells (hipp-NS/PCs) of the adult mammalian brain are important sources of neuronal and gial cell production. In this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. To this end, the differentiation of the hipp-NS/PCs isolated from 3-month-old Wistar rats was investigated in response to the embryonic...
