Whole blood serotonin levels in young men were investigated during exposure to a 4% carbon dioxide environment (PICO2 = 29.9 mm. Hg) for a 10-day period. No significant change in serotonin levels was found in those men acting as outside controls at ambient (0.03%) carbon dioxide, but ...

Conclusion Both HFNC and NIPPV treatments can effectively improve RR and blood gas indexes in patients with AECOPD complicated with type Ⅱ respiratory failure. Higher level of RR at admission and 72-hour fluid balance volume are the risk factors of failure of HFNC in treatment of AECOPD patients...
Briefly, music puts you in high spirits, which makes you better at studying - but it also distracts you, which makes you worse at studying. So if you want to study effectively with music on, you can try to reduce how distracting music can be, and increase the level to which music kee...
Hemoglobin (sometimes abbreviated as Hb) is a complex protein found in red blood cells that contains an iron molecule. The main function of hemoglobin is to carry oxygen from the lungs to the body tissues, and to exchange the oxygen for carbon dioxide, and then carry the carbon dioxide back...
Embedded within the heme compound is an iron atom that is vital in transporting oxygen and carbon dioxide in our blood. The iron contained in hemoglobin is also responsible for the red color of blood. It also plays an important role in maintaining the shape of the red blood cells. In ...
Changes in cerebral blood flow (CBF) may occur with acute exposure to high altitude; however, the CBF of the brain parenchyma has not been studied to date. In this study, identical magnetic resonance scans using arterial spin labeling (ASL) were performe
Energy consumption per unit of GDP dropped by 8.1 percent, and carbon dioxide emissions fell by 14.1 percent. In cities at and above the prefecture level, the average concentration of fine particulate matter (PM2.5) dropped by 27.5 percent and the number of days with heavy air pollution fell ...
