'Dead Zone' causing wave of death off Oregon coast
The most severe low-oxygen ocean conditions ever observed on the West Coast of the United States have turned parts of the seafloor off Oregon into a carpet of dead Dungeness crabs and rotting sea worms, a new survey shows. Virtually all of the fish appear to have fled the area. view more (2006-08-11)
New groundbreaking treatment for oxygen-deprived newborns
Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. view more (2009-08-11)
Cancer cells 'reprogram' energy needs to grow and spread, study suggests
Studying a rare inherited syndrome, researchers at Johns Hopkins have found that cancer cells can reprogram themselves to turn down their own energy-making machinery and use less oxygen, and that these changes might help cancer cells survive and spread. view more (2007-05-08)
Increasing carbon dioxide and decreasing oxygen in the oceans will make it harder for deep-sea animals to
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. view more (2009-04-20)
Biofuel production could undercut efforts to shrink Gulf 'Dead Zone'
Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. view more (2009-09-17)
Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor. view more (2008-08-05)
Measuring fetal oxygen does not reduce Caesarean rate, researchers find
Measuring the amount of oxygen in the blood of a fetus during labor has no bearing on whether a Caesarean section is performed and does not affect the health of the newborn baby, researchers at UT Southwestern Medical Center have found in a multicenter study. view more (2006-11-27)
New bone marrow model could help people with sickle cell disease
A new model showing how sickle cell blood cells operate within bone marrow is presented at a conference in Austria today. Researchers at Imperial College London, who developed the model, hope that it will eventually be used by clinicians to advance more effective treatments for sickle cell disease. This disease causes red blood cells to become... view more... (2005-02-18)
LSUHSC study finds high-dose HBO2 therapy extends survival window after cardiopulmonary arrest
A ground-breaking study by researchers at the School of Medicine at LSU Health Sciences Center New Orleans published in the August 2008 issue of Resuscitation has major implications for the #1 cause of death of Americans -- sudden cardiac arrest. view more (2008-07-16)
Biologists ID molecular basis of high-altitude adaptation in mice
Biologists have long known how adaptive evolution works. New mutations arise within a population and those that confer some benefits to the organism increase in frequency and eventually become fixed in the population. view more (2009-08-11)
Researchers identify genetic switch critical for cell survival in hypoxia
Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. view more (2008-10-17)
Oxygen + MRI might help determine cancer therapy success
A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center. view more (2009-06-03)
Music played to premature babies may lessen pain and improve feeding habits
Music played to premature babies may help to reduce their pain and encourage better oral feeding, suggests research published ahead of print in the Archives of Disease in Childhood. view more (2009-05-28)
The healing power of Hydrogen Peroxide
Hydrogen peroxide is usually used for cleansing scratches and cuts. However, this is not the only one possible application of this substance in medicine. The vapor of a low-concentrated peroxide solution containing oxygen radicals can be used as an inhalant for an additional treatment of many illnesses. This has been established by the research... view more... (2002-04-19)
HFI-1 gene has key role in both oxygen sensing, heat shock pathway
University of Oregon researchers have found an unexpected regulatory link between cellular responses to hypoxia and heat shock. Central to the discovery is a gene known as Hypoxia-Inducible Factor-1 (HIF-1) that is critical for both normal and pathological changes, making it a potential target for both health promotion and cancer therapies. view more (2006-10-26)
New light on link between snoring and cognitive deficits in children
About two-thirds of children with sleep-disordered breathing (SDB)- snoring or obstructive sleep apnea (OSA)- have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the SDB. view more (2008-10-07)
Helium helps lung patients breathe easier
New research published in the international journal Chest, by Neil Eves, PhD, finds that people with chronic obstructive pulmonary disease (COPD) who breathed a mix of 60% helium and 40% oxygen during a rehabilitation program were able to exercise longer and harder than those who breathed normal air. view more (2009-03-10)
Researchers figure out how hearts fail
Researchers have determined how metabolic pathways differ between healthy and failing hearts. Normally, a heart derives its energy from a balance of fatty acids and carbohydrates, specifically glucose. view more (2005-07-25)
Oxygen-saturated blood reduces levels of damaged heart tissue following a heart attack
Results of a clinical trial published today in Circulation: Cardiovascular Interventions demonstrate that an infusion of blood that is "supersaturated" with oxygen (SS02) can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack. view more (2009-09-16)
Harnessing Microbes to Kill Cancer
An ingenious new way to attack cancer tumours is being developed by medical researchers from Nottingham as part of an EU consortium, the Society for General Microbiology's Spring Meeting in Edinburgh heard today, Tuesday 8 April 2003. The problem with powerful anti-cancer drugs is that they kill healthy cells too, and concentrations needed to wipe... view more... (2003-04-02)
