Latest Hypoxia Stories
Research may have implications for heart disease, stroke and cancer Scientists at the Gladstone Institutes have identified a protein that kick–starts the response to low levels of oxygen, suggesting new lines of research relevant to a variety of potentially fatal disorders associated with diminished oxygen supply, including cancer, heart disease, stroke and other neurological conditions that affect millions of people worldwide. In a paper being published today in Molecular Cell, the...
The latest results from an expedition to Mount Everest that looked at the body's response to low oxygen levels suggest that drugs or procedures that promote the body's production of a chemical compound called nitric oxide (NO) could improve the recovery of critically ill patients in intensive care. Oxygen is required by all larger organisms, including humans, to survive. Many critically ill patients suffer from a shortage of oxygen (a condition known as 'hypoxia'), which can be...
ORCHARD, Texas, July 1, 2011 /PRNewswire/ -- The Company believes the Alternative Oxygen Therapy industry is poised for explosive growth. Oxygen Orchard, Inc. has been instrumental in shaping this new industry with its innovative products, informed by years of medical and scientific research. Enormous marketing opportunities exist for non-pharma biotech and the Company. The National Institutes of Health reports that 88,000,000 American adults used alternative medicine in 2009. This...
The Gulf of Mexico's "dead zone" is predicted to be the largest ever recorded due to extreme flooding of the Mississippi River this spring, according to a team of scientists working through the support of the National Oceanic and Atmospheric Administration (NOAA). The scientists, from the Louisiana Universities Marine Consortium, Louisiana State University and the University of Michigan, based their forecast on Mississippi River nutrient inputs compiled annually by the US Geological Survey...
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, according to researchers in Spain. The study also found tumor cells of OSA mouse models tended to contain more dead cells, indicating a more aggressive type of cancer.The results of the study will be presented at the ATS 2011 International Conference in Denver."To our knowledge, this...
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. The ability of SiMoA to...
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. However, the blood vessels in the lungs react differently: blood pressure in the lungs rises, often with deleterious effects on the lungs' tissue and the heart. Larissa A. Shimoda, PhD, Associate Professor of Medicine at the Johns Hopkins University School...
Low oxygen may spur genes to create blood vesselsIn 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."If living in a lower oxygen environment such as in our Colorado mountains helps reduce the risk of dying from heart disease it...
University of Colorado researchers focus on how the body adaptsWhen the body is deprived of oxygen during a major surgery, the kidneys, heart muscles or lungs can be injured as a result. The problem is that lack of oxygen can lead to inflammation.Yet some athletes deliberately train at high altitude, with less oxygen, so they can perform better. Their bodies adapt to the reduced oxygen.Now a doctor at the University of Colorado School of Medicine has explored the relationship between lack of...
New research in the FASEB Journal suggests that there are extensive but reversible changes in the heart when it is exposed to low oxygen levels similar to those caused by many diseasesFrom 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 the study, researchers...
