In Mycobacterium tuberculosis, the sensor kinases DosT and DosS activate the transcriptional regulator DosR, resulting in the induction of the DosR regulon, which is important for anaerobic survival and perhaps latent infection. The individual and collective roles of these sensors have been postulated biochemically, but their roles in vivo have remained unclear. This work demonstrates distinct ...

The Mg(BiO2)2 is the orthorhombic crystal system acting as semiconductor in electric devices. To evaluate electronic band structures, the total density of state (TDOS) and the partial density of state (PDOS), Generalized Gradient Approximation (GGA) based on the Perdew–Burke–Ernzerhof (PBE0) was used for Mg(BiO2)2. The band gap was recorded at 0.959 eV, which is supported by a good semiconducto...

Lung morpho-functional alterations and inflammatory response to various types of mechanical ventilation (MV) have been assessed in normal, anesthetized, open-chest rats. Measurements were taken during protective MV [tidal volume (Vt) = 8 ml/kg; positive end-expiratory pressure (PEEP) = 2.6 cmH(2)O] before and after a 2- to 2.5-h period of ventilation on PEEP (control group), zero EEP without (Z...

The electronic structures of the luminescent center ions Cr3+ and Fe3+ in deep red phosphors LiAl5O8:Cr3+, ?-Al2O3:Cr3+, ?-LiAlO2:Fe3+ were calculated by DV-X? method, which local distortion induced replacement Al3+ sites host crystals was reproduced classical molecular dynamics (MD) simulation. MD simulations based on allowed for handling more than 1000 atoms lattice relaxation calculations, a...

in present work, we have calculated the electronic properties including density of states (dos) and electron density for gan, inn and in wurtzite phase for x=0.5. the study is based on density functional theory (dft) with full potential linearized augmented plane wave method (fp-lapw) by generalized gradient approximation (gga-pbesol) for calculating electronic properties. in this report we con...

First-principles calculations based on density functional theory have been performed for the quaternary GaAs1-x-y N x Bi y alloy lattice-matched to GaAs. Using the state-of-the-art computational method with the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional, electronic, and optical properties were obtained, including band structures, density of states (DOSs), dielectric function, absorption co...
