At the present theoretical study, DFT calculations were performed for elucidating thereaction, absorption energy and the quantum molecular descriptors including electronic chemical potential, chemical hardness, Homo, Lumo, band gap energy (Eg) and finding the most active nitrogen-doped graphene sheet (N-G) for absorption H2S, CH4, N2 and CO2 gases. Finally it found that nitrogen-doped gra...

Death after hemorrhagic shock (HS) may be caused by a generalized reperfusion injury, particularly noticeable in the gut. A period of tissue ischemia followed by reinstitution of perfusion produces severe inflammation that can be blocked in mice by preventing the binding of a pathogenic natural immunoglobulin M (IgM) of defined specificity to antigens in reperfused tissue by using a soluble pep...

Background: Considerable studies showed associations between chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD), we evaluated the role of endogenous hydrogen sulfide (H2S)/homocysteine (Hcy) in patients with COPD combined with CVD. Methods: Fifty one stable patients with COPD were enrolled (25 COPD, 26 COPD + CVD). Lung function, sputum, peripheral blood samples, seru...

Ionic liquids (ILs) are proposed as potential “green” solvents with remarkable properties. Deep eutectic (DESs) a new type of ILs additional properties, such higher biodegradability and lower price. DESs absorbents for various gas separations, CO2/N2, CO2/H2/CO, H2S/CH4, N2O/N2. Due to their large number, the screening is crucial. Although high absorption capacities were screened using solubili...
