by British Medical Journal The combination of alcohol plus cabin pressure at cruising altitude may threaten sleeping plane passengers’ heart health, particularly on long-haul flights, suggests the first study of its kind, published in Thorax. The duo lowers the amount of oxygen in the blood (SpO2) and raises the heart rate for a protracted period,...

Low-Frequency Ultrasound Can Increase the Amount of Oxygen in the Blood
A team of scientists from Kaunas University conducted research that unveiled the impact of low-frequency ultrasound on blood parameters. The findings suggest that the influence of ultrasound on hemoglobin can enhance the transfer of oxygen from the lungs to the body’s tissues. Blood – artistic visualization. The study involved the analysis of 300 blood samples...

Scientists develop synthetic blood-thinner that doesn’t cause bleeding side-effects
by Ecole Polytechnique Federale de Lausanne gulation factor XII (FXII), and the mice without the enzyme had a highly reduced risk of thrombosis without bleeding side-effects. The discovery triggered a race for FXII inhibitors. The Laboratory of Therapeutic Proteins and Peptides of Professor Christian Heinis at EPFL has now developed the first synthetic inhibitor of...

Scientists decipher key mechanism in hypoxia
by Centro Nacional de Investigaciones Cardiovasculares Carlos III (F.S.P.) The figure illustrates the role of the mitochondrial Ca2+/Na+ exchanger (NCLX) in the early adaptation to low oxygen concentrations (hypoxia) through the entry of sodium into the mitochondrial interior. This role is exemplified by hypoxic vasoconstriction of the pulmonary artery, which connects the heart to the...

Using Epo to treat COVID-19
by Max Planck Society Erythropoietin (Epo) is actually a medication for anemia. According to researchers at the Max Planck Institute of Experimental Medicine in Göttingen, the doping agent Epo could also be effective against COVID-19. The growth factor could mitigate severe disease progression and protect patients from long-term neurological effects when the SARS-CoV-2 virus attacks...
