Oxygen deprived brains repaired and saved
Scientists from Melbourne's Howard Florey Institute have found special proteins that protect the brain after it has been damaged by a lack of oxygen, which occurs in conditions such as stroke, perinatal asphyxia, near-drowning and traumatic brain injury. view more (2006-08-25)
Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death. view more (2007-06-08)
The coward of the coral reef
The broad barred goby is a coward. A sweeping statement you may say, but even though the goby is poisonous to its predators, the cowardly fish still spends almost all its time cowering in an inaccessible coral home 20-30 cm in diameter. A new study, to be presented to the Society for Experimental biology on Wednesday 3rd April, reveals how the... view more... (2003-04-01)
DVT Risk From Air Travel Unrelated To Reduced Air Pressure In Cabin (p 2207)
Results of a study published as a research letter in this week's issue of THE LANCET suggest that reduced air pressure (leading to decreased oxygen availability) in pressurised aircraft cabins is not associated with increased activity of the agents responsible for blood clotting and potential deep-vein thrombosis (DVT). The risk of venous... view more... (2003-06-25)
Genes may interact with obstetric complications to boost schizophrenia risk
The cause of schizophrenia is thought to include both epistasis and gene-environment interactions. view more (2008-01-15)
The mental health dangers of birth hypoxia
Complications during pregnancy and birth, such as birth hypoxia - the shortage of oxygen in the body - are associated with an increased risk for schizophrenia. view more (2008-10-28)
New sensor to provide early warning of oxygen loss to unborn children
esearchers at the University of Warwick, and the University Hospitals Coventry and Warwickshire NHS Trust, have devised a new sensor which has the power to dramatically improve the amount of early warning doctors and midwives get of a dangerous situation in the birth process when the unborn child's brain is starved of oxygen-Fetal Hypoxia. view more (2006-02-14)
Hypoxia training suppresses harmful cardiac nitric oxide production during heart attack
Researchers at the University of North Texas Health Science Center, Fort Worth, Texas have demonstrated that, contrary to prevailing dogma, hypoxia can be remarkably beneficial to the heart. These discoveries, to be reported in the June 2008 issue of Experimental Biology and Medicine, may lead to a new paradigm to protect hearts of patients at... view more... (2008-05-27)
Low oxygen in coastal waters impairs fish reproduction
Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes' hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found. view more (2007-08-29)
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)
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)
Long-term study shows low oxygen levels in prostate tumors can predict recurrence
Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer. view more (2009-05-18)
SUMO-Wrestling with Thin Air
When the flow of blood to an organ or tissue is disrupted, cells become starved of oxygen. The inflammation that occurs as a result of this can be seen in many diseases. Inflammation in the gut is a significant event in Crohn's disease. Understanding how the body responds to oxygen deprivation (hypoxia) is the key to identifying new targets for... view more...

Exploring how the body adapts to exercise at altitude-hypoxia affects muscle and nerve responses
Exercise requires the integrated activity of every organ and tissue in the body, and understanding how these respond to the decreased oxygen levels present at moderate to high altitude is the focus of the current special issue of High Altitude Medicine & Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. view more (2009-06-30)
Sleep Apnea Increases Heart Disease Risk
Obstructive sleep apnea, or periodic interruptions in breathing throughout the night, thickens sufferers' blood vessels. Moreover, it increases the risk of several forms of heart and vascular disease. view more (2009-05-05)
Simple drug treatment may prevent nicotine-induced SIDS: Study
A new study has identified a specific class of pharmaceutical drugs that could be effective in treating babies vulnerable to Sudden Infant Death Syndrome (SIDS), because their mothers smoked during pregnancy. view more (2009-06-03)
A new gene trigger for pregnancy disorder identified
The COMT gene - known already for its role in schizophrenia - has been found to play a role in preeclampsia, according to a report in today's advance on-line issue of Nature. view more (2008-05-12)
Scientists unlock solid tumor treatment genetic secrets
A biochemical mechanism that cells use to cope with hypoxia (lack of oxygen) actually cooperates with a less well-known mechanism that helps increase the expression of those hypoxia-sensitive genes. view more (2005-12-02)
Link between chronic kidney disease and oxygen-deprived tissue
Researchers at the University of Pennsylvania School of Medicine have discovered how low-oxygen conditions can worsen chronic kidney disease (CKD). view more (2007-12-19)
Long airplane flight does not appear to increase risk of blood clots
Researchers simulating conditions of reduced cabin pressure and reduced oxygen levels, such as may be encountered during an 8-hour airplane flight, found no increase in the activation of the blood clotting system among healthy individuals. view more (2006-05-17)
