The exposure of cells to several metal ions stabilizes HIF-1 alpha protein. However, the molecular mechanisms are not completely understood. They may involve inhibition of hydroxylation by either substitution of iron by metal ions or by iron oxidation in the hydroxylases. Here we provide evidence supporting the latter mechanism. We show that HIF-1 alpha stabilization in human lung epithelial ce...

Critical MANET environments such as military battlefields and disaster recovery operations impose a number of requirements (such as the need for robustness and performance within a high mobility scenarios), and constraints (such as Hostile attacks, RF range and cost, battery limitations). Many studies proved that PUMA (Protocol for Unified Multicasting through Announcements) is superior compare...

We show how the mechanism of electron transfer through molecules can be switched between different regimes by using Hg-based metal–molecules–metal junctions. The junctions are easy to assemble and allow for hosting of self-assembled monolayers (SAMs) of a large variety of molecular structures. In this paper, we compare results from studies of charge transport across two different types of junct...

The separation of mercury ions from artificially contaminated water by the foam fractionation process using a biosurfactant (surfactin) and chemical surfactants (SDS and Tween-80) was investigated in this study. Parameters such as surfactant and mercury concentration, pH, foam volume, and digestion time were varied and their effects on the efficiency of mercury removal were investigated. The re...

several studies have shown that oil recovery significantly increased by low salinity water flooding (lswf) in sandstones. however, mechanism of oil recovery improvement is still controversial. co2 that develops buffer in presence of water is expected as a deterrent factor in lswf efficiency based on mechanism of ift reduction due to ph uprising. no bright evidence in literature supports this id...
