endothelial cells present in brain are unique and differ from other peripheral tissues in a number of ways, which ensures specific brain endothelial barrier properties. endothelial dysfunction is the earliest event in the initiation of vascular damage caused by inflammation. various micrornas (mirna) have been discovered in different cellular components of the blood bran barrier (bbb). mirnas a...

Endothelial cells present in brain are unique and differ from other peripheral tissues in a number of ways, which ensures specific brain endothelial barrier properties. Endothelial dysfunction is the earliest event in the initiation of vascular damage caused by inflammation. Various microRNAs (miRNA) have been discovered in different cellular components of the blood bran barrier (BBB). miRNAs a...

microglia, the sentries of the brain, is highly implicated in neurodegeneration as in neuroprotection. chronic microglial activation endangers neuronal survival through the release of various potentially neurotoxic mediators including nitric oxide (no). thus, negative regulators of microglial activation have been considered as potential therapeutic candidates to target neurodegeneration, such a...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

one of the major classes of ionotropic glutamate receptors is the class of n-methyl-d-aspartate receptors (nmdars). receptor activation recruits, via calcium signal transduction mechanisms which play important roles in oxidative metabolism, mitochondrial free radical production and occurrence of other mitochondrial factors which potentially contribute to excitotoxicity and neuronal death. in...

It has been hypothesized that elevated plasma Homocysteine (Hcy) plays a role in the pathogenesis of Alzheimer’s disease (AD) and age-related cognitive decline. The mechanism of Hcy neurotoxicity in the brain is controversial as well Hcy is a ligand of NMDA receptor. Memantine, an uncompetitive antagonist of N-methyl-D-aspartate (NMDA) receptors approved for the treatment of moderate to severe ...
