The Mycobacterium tuberculosis dosR gene (Rv3133c) is part of an operon, Rv3134c-Rv3132c, and encodes a response regulator that has been shown to be upregulated by hypoxia and other in vitro stress conditions and may be important for bacterial survival within granulomatous lesions found in tuberculosis. DosR is activated in response to hypoxia and nitric oxide by DosS (Rv3132c) or DosT (Rv2027c...
In this paper, we study the electronic conductance and density of states for a comb-like polymer with periodic hopping energies in the tight-binding approach. Electron transmission coefficient and density of states are analytically calculated by using Green’s function of the system. The results show that the electronic conductance spectrum has one energy gap in the absence of carbon-hydrogen b...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
The effect of impurities on quantum chemical parameters of single-walled nanotubes (SWNTs) was studied using density functional theory (DFT). The density of states (DOS), Fermi energy and thermodynamic energies of (5,5) carbon nanotubes were calculated in the presence of nitrogen impurity. It was found that this nanotube remains metallic after being doped with one nitrogen atom. The partial den...
Greater trochanteric pain syndrome (GTPS) is a common condition resulting in posterolateral hip pain typically in perimenopausal women. Gluteal tendinopathy is the underlying pathology and contributes to health care cost burden as a poorly managed tendon disorder. There is no established effective treatment for gluteal tendon pathology in GTPS. This article describes clinical, imaging and life ...
In this paper, some electronics properties of new superconductor Sr2VO3FeAs, such as density of states, band structure, density of electron cloud and bound lengths in the ground state have been calculated. According to N(Ef) in ground state CV/T value has been estimated. The calculations were performed in the framework of density functional theory (DFT), using the full potential linearized augm...
In present work, we have calculated the electronic properties including density of states and electron density for GaN, InN and InxGa1-xN in wurtzite phase for x=0.5. The study is based on density functional theory with full potential linearized augmented plane wave method by generalized gradient approximation for calculating electronic properties. In this report we concluded that InxGa1-xN ba...
After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants, current studies to date focus on the anionic surfactant, bis-(2-eth...
Genistein (5,7,4′-trihydroxyisoflavone) is an isoflavone abundantly found in soy and other legumes acts as a selective estrogen receptor modulator (SERM). When testing for similar abilities among flavonoids, it has been to be strong topoisomerase inhibitor. Similar some high-dose chemotherapy drugs, was strongly toxic normal cells. In this study, the adsorption of genistein on surface exclusive...
