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 vessels 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. "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 adapts When 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...

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 diseases 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 the study, researchers...

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. Their findings, to be published online by the journal of the Proceedings of the National Academy of Sciences (PNAS) the week of January 24, 2011, may lead to new targets for development of...

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. Tomas Höök, an assistant professor of forestry and natural resources, and former Purdue postdoctoral researcher Kristen Arend used output from a model to estimate how much dissolved oxygen was present in Lake Erie's hypoxic zone each day from 1987...

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. New experiments in raising modern insects in various oxygen-enriched atmospheres have confirmed that dragonflies grow bigger with more oxygen, or hyperoxia. However, not all insects were larger when oxygen was higher in the past. For instance, the largest cockroaches ever are skittering around today. The question...

Research: Effect of high flow oxygen on mortality in chronic obstructive pulmonary disease patients in pre-hospital setting: Randomized controlled trial 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%, according to a new study published on bmj.com today. Researchers based in Australia found the risk of death in patients with chronic obstructive pulmonary disease (COPD) was significantly reduced by...
