Soluble guanylate cyclase (sGC) enzyme is activated by the gaseous signaling agent nitric oxide (NO) and triggers the conversion of GTP (guanosine 5′-triphosphate) to cGMP (cyclic guanylyl monophosphate). It contains the heme binding H-NOX (heme- nitric oxide/oxygen binding) domain which serves as the sensor of NO and it is highly conserved across eukaryotes and bacteria as well. Many...

In: Journal of Global Antimicrobial Resistance, 2020, vol. 22, p. 832–834

Objectives: This study describes the first draft genome sequence of a multidrug- resistant (MDR) Escherichia coli D-ST69 clinical isolate from Egypt carrying blaNDM-1 and blaOXA-244.Methods: The strain was isolated in December 2014 from a wound pus swab of a male patient in the city of Kafr El-Sheikh using MacConkey agar containing 2 μg/mL meropenem. The strain was subjected to antimicrobial ...

Hypersatellite x-ray decay of $3d$ hollow-$K$-shell atoms produced by heavy-ion impact

We report on the radiative decay of double K-shell vacancy states produced in solid Ca, V, Fe, and Cu targets by impact with about 10 MeV/amu C and Ne ions. The resulting K hypersatellite x-ray emission spectra were measured by means of high- energy-resolution spectroscopy using a von Hamos bent crystal spectrometer. The experiment was carried out at the Philips variable energy cyclotron of...

Electronic fine structure calculation of metal complexes with three-open-shell s, d, and p configurations

Ramanantoanina, Harry ; Daul, Claude

In: Journal of Molecular Modeling, 2017, vol. 23, no. 8, p. 243

The ligand field density functional theory (LFDFT) algorithm is extended to treat the electronic structure and properties of systems with three-open-shell electron configurations, exemplified in this work by the calculation of the core and semi-core 1s, 2s, and 3s one-electron excitations in compounds containing transition metal ions. The work presents a model to non-empirically resolve the...
