Oxygen treatment for severe asthma could save lives
Asthmatic patients are still dying during severe attacks, yet making oxygen available in every general practice to treat patients with a life threatening asthma attack could save lives, concludes a study in this week's BMJ. The authors urge the British Thoracic Society to review this issue when it updates its asthma guidelines. A research team in... view more... (2001-07-11)
Oxygen Treatment - New guidelines for use inside and outside the home
Oxygen therapy has long been recognised as helping some patients with COPD live longer, and it is estimated that around 18,000 patients benefit from the treatment each year in the UK. view more (1999-07-23)
Toxic to aliens -- but key to health of planet
Scientists at the University of Leicester are using an ingredient found in common shampoos to investigate how the oxygen content of the oceans has changed over geologically recent time. view more (2008-06-19)
Should People With Diabetes Sleep With The Lights On?
A research letter in this week's issue of THE LANCET suggests that night-time illumination could help prevent the onset of diabetic retinopathy, a condition which can result in severe visual impairment in people with diabetes. People with diabetes generally have impaired blood capillary function, which reduces oxygen uptake to body tissue,... view more... (2002-06-26)
The beat goes on: a vertebrate heart that beats without oxygen
Scientists have discovered that the heart of a carp keeps beating when it is starved of oxygen for five days. "This is the first time that a vertebrate heart has been shown to survive such prolonged periods without oxygen and actually keep beating at the same rate as when oxygen is available" says Jonathan Stecyk (Simon Fraser... view more...

54 per cent of air passengers experience significant reductions in oxygen levels
More than half of air travellers find that their oxygen saturation drops to a level at which many hospital patients would be prescribed extra oxygen, according to a paper in the May issue of Anaesthesia. view more (2005-04-25)
Alligators hint at what life may have been like for dinosaurs
During the last 540 million years, the earth's oxygen levels have fluctuated wildly. Knowing that the dinosaurs appeared around the time when oxygen levels were at their lowest at 12%, Tomasz Owerkowicz, Ruth Elsey and James Hicks wondered how these monsters coped at such low oxygen levels. view more (2009-04-17)
Medical breakthrough for organ transplants and cardiovascular diseases by Flemish researchers
When a blood vessel clogs up, a localized deficiency of oxygen results, causing the surrounding tissue to die. However, working with mice, VIB scientists connected to the Katholieke Universiteit Leuven have been able to prevent muscular tissue with severe hypoxia from dying. view more (2008-01-07)
Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body. view more (2005-12-29)
Oxygen increase caused mammals to triumph, researchers say
The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet. view more (2005-09-30)
Computers explain why pears may become brown during commercial storage
Internal browning of pears stored under low oxygen conditions is related to restricted gas exchange inside the fruit, according to a study published March 7th in the open-access journal PLoS Computational Biology. view more (2008-03-10)
Air Rather Than Oxygen For Babies Requiring Ventilation After Delivery (pp 1293, 1329)
Provision of air rather than 100% oxygen for babies requiring ventilation after delivery could reduce infant mortality, suggests a study in this week's issue of THE LANCET. The finding is counter to the long-held belief that 100% oxygen is better than air for babies requiring ventilation in the first few minutes of life. view more (2004-10-06)
Bonn scientists discover new hemoglobin type
Scientists at the University of Bonn have discovered a new rare type of haemo-globin. Haemoglobin transports oxygen in the red blood corpuscles. view more (2008-03-18)
Patients receiving supplemental oxygen during surgery have reduced risk of wound infection
Patients who received a higher concentration of supplemental oxygen during colorectal surgery had a significantly reduced risk of wound infection. view more (2005-10-26)
Ancient oceans offer new insight into the origins of animal life
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. view more (2009-09-10)
Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in Alberta, Canada. view more (2005-08-05)
Microbes in mud flats clean up oil spill chemicals
Micro-organisms occurring naturally in coastal mudflats have an essential role to play in cleaning up pollution by breaking down petrochemical residues. view more (2009-03-30)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
Helium helps patients breathe easier
It makes for bobbing balloons and squeaky voices, but now helium is also helping people with severe respiratory problems breathe easier. view more (2007-02-02)
Enzyme may be a key to Alzheimer's-related cell death
A Purdue University researcher has discovered that the amount of an enzyme present in neurons can affect the mechanism thought to cause cell death in Alzheimer's disease patients and may have applications for other diseases such as stroke and heart attack. view more (2009-10-08)
