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 ...
Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is routinely measured as part of a routine blood test termed blood count (CBC). A complete blood count is...

If you’ve been diagnosed with high blood pressure, you might be worried about taking medication to bring your numbers down. Chronic(慢性的) stress may contribute to high blood pressure. More research is needed to determine the effects of chronic stress on blood pressure. Occasional stress also...
Hemoglobin (abbreviated Hgb or Hb) is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hgb is made up of four protein molecules (globulin chains) that are connected. The normal ...
Long-term exposure to hyperglycemic conditions leads to β-cell dysfunction, particularly mitochondrial dysfunction, and inflammatory and oxidative stress responses, which are considered the primary causes of β-cell death and the hallmarks of diabetes.
Indicators of inflammation (white blood cells, hydrogen peroxide production, and IL-1 and IL-8 cytokine mRNA expression in cells from the alveolar wash) qualitatively indicated less injury in the high PCO2 group, although the differ- ences were not significant. Preterm lambs tolerated a very...
carbon dioxide production, respiratory quotient, and animal locomotion (all meters) were determined and analyzed over a ten-day period33. All data (besides RER and all meters = two-tailed student’s T-test) were analyzed using an ANCOVA with lean mass as a covariate utilizing the MMPC ...
Near-infrared spectroscopy (NIRS) has been used in conjunction with EMG and achieved a higher decoding performance in a prosthesis, compared to using each method individually32, in which NIRS adds the blood oxygen information during muscle movement. Sheng et al. integrated EMG, MMG, and NIRS ...
Zokors, an Asiatic group of subterranean rodents, originated in lowlands and colonized high-elevational zones following the uplift of the Qinghai–Tibet plateau about 3.6 million years ago. Zokors live at high elevation in subterranean burrows and experience hypobaric hypoxia, including both hypoxia (...
