Latest Hypoxia Stories
A new study links the intermittent interruption of breathing that occurs in patients with obstructive sleep apnea (OSA) to enhanced proliferation of melanoma cancer cells and increased tumor growth in mice.
CAMBRIDGE, Mass., April 12, 2011 /PRNewswire/ -- Quanterix Corporation, enabling a new generation of diagnostics based on revolutionary Single Molecule Array (SiMoA(TM)) technology, today announced that significant elevations in blood levels of amyloid beta (Abeta) 42 peptide, a component of the plaques that are a hallmark of Alzheimer's disease, were detected in patients who experienced hypoxia (inadequate supply of oxygen to the brain) following cardiac arrest.
When muscles and organs are deprived of an adequate supply of oxygen--a condition called hypoxia--the body's usual responses include increased circulation and a slight drop in blood pressure in the blood vessels serving the affected tissue.
In one of the most comprehensive studies of its kind, researchers at the University of Colorado School of Medicine in partnership with the Harvard School of Global Health have found that people living at higher altitudes have a lower chance of dying from ischemic heart disease and tend to live longer than others.
When the body is deprived of oxygen during a major surgery, the kidneys, heart muscles or lungs can be injured as a result.
From the highest mountaintop comes a new research report in the FASEB Journal (http://www.fasebj.org) that gets to the bottom of what happens to the hearts of people when exposed to low-levels of oxygen, such as those on Mount Everest or in the intensive care unit of a hospital.
In an important study that may shed light on human ability to adapt to hypoxia, or inadequate levels of oxygen, researchers at the University of California, San Diego School of Medicine have proven that the genome of flies exposed to long-term hypoxia are changed to permanently affect gene expression.
Large hypoxic zones low in oxygen long have been thought to have negative influences on aquatic life, but a Purdue University study shows that while these so-called dead zones have an adverse affect, not all species are impacted equally.
The giant dragonflies of ancient Earth with wingspans of up to 70 centimeters (28 inches) are generally attributed to higher oxygen atmospheric levels in the atmosphere in the past.
A change to the way paramedics use oxygen when treating patients with chronic lung disease could cut the death rate in these cases by up to 78%.
