Abstract The influence of magnesium on roasting vanadium slag was investigated by simulating the roasting process of vanadium by mixing V2O5 and MgO. The calcination products of V2O5 reacted with MgO at different temperatures which were characterized by X-ray diffraction (XRD), Thermogravimetry-differential scanning calorimetry (TG-DSC) and scanning electron microscope (SEM). There were two mass loss intervals, three endothermic peaks and one exothermic peak appearing during the reaction by the integrated thermal analysis as the temperature increased from room temperature to 1273.15 K. The samples of mixed V2O5 an...

Authors: Qian WJ, Li L, Sun LY, Shi HR, Liu H, Jing X Abstract Novel coronavirus disease-19 (COVID-19) has widely spread all over the world and seriously threatened people's health. This disease is currently diagnosed by clinical features, chest computed tomography (CT) scan, and nucleic acid test of severe acute respiratory syndrome coronavirus (SARS-CoV-2). Recently, some studies have suggested parenchymal consolidation and air bronchogram in severe cases. However, the effective treatment for COVID-19 patients with bronchogram has not been discussed. Herein, we report a case of 47-year-old woman who suffered from...

CONCLUSIONS: Oxidative stress and Inflammation significantly correlate with OSA; similarly, vascular functioning is impaired in accordance to unregulated levels of NO and derived compounds. Continuous Positive Airway Pressure markedly improves oxidative stress, inflammation and endothelial dysfunction in OSA. PMID: 32633387 [PubMed - in process]
