Adaptation to oxygen deprivation elucidates tumor physiology
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.   view more (2006-03-08)

Second low-oxygen pathway hints at cancer, cardiovascular disease physiology
Researchers at the University of Pennsylvania School of Medicine have identified a second molecular pathway that promotes cell survival in low-oxygen conditions.   view more (2006-02-17)

'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)

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)

Ocean 'dead zones' trigger sex changes in fish, posing extinction threat
Oxygen depletion in the world's oceans, primarily caused by agricultural run-off and pollution, could spark the development of far more male fish than female, thereby threatening some species with extinction.   view more (2006-03-30)

Inhaled nitric oxide may help sickle cell disease
Inhaling a small dose of nitric oxide gas may one day help sickle cell patients avoid pain crises and live healthier lives, researchers say.   view more (2005-10-24)

Marine 'dead zone' off Oregon is spreading
A hypoxic "dead zone" has formed off the Oregon Coast for the fifth time in five years, according to researchers at Oregon State University.   view more (2006-07-28)

Ways to avoid hazards of heart bypass under study
The heart-lung bypass machine that stills the heart while surgeons bypass an adult's clogged arteries or repair a baby's malformed heart can also trigger a potentially deadly inflammatory response.   view more (2005-08-29)

Cool therapy reduces brain injury and death from oxygen loss in newborns
Infants born with oxygen loss who are given an innovative therapy that lowers their entire body temperature by four degrees within the first six hours of life, have a better chance of survival and lower incidence of brain injury.   view more (2005-10-14)

Perinatal complications linked to eating disorders
Certain complications during and immediately after birth are associated with the development of the eating disorders anorexia nervosa and bulimia nervosa.   view more (2006-01-03)

Pomegranate juice for moms may help babies resist brain injury
Expectant mothers at risk of premature birth may want to consider drinking pomegranate juice to help their babies resist brain injuries from low oxygen and reduced blood flow, a new mouse study from Washington University School of Medicine in St. Louis suggests.   view more (2005-06-28)

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)

Stanford scientists identify protein involved in fast-spreading cancers
Researchers at the Stanford University School of Medicine have found a protein that may explain why tumors in a low-oxygen environment are more deadly.   view more (2006-04-27)

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)

Alternative farming cleans up water
Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leach nutrients, polluting the water supply.   view more (2007-07-20)

New tool tracks brain development in babies
Researchers have used a new technique to monitor brain development in infants and detect disturbances in white matter, according to a study in the July issue of Radiology.   view more (2006-06-27)

Deadly hypoxic event finally concludes
The longest, largest and most devastating hypoxic event ever observed in marine waters off the Oregon Coast has finally ended.   view more (2006-10-31)

Seals protect brain, conserve oxygen by turning off shivering response on icy dives
Seals shiver when exposed to cold air but not when diving in chilly water, a finding that researchers believe allows the diving seal to conserve oxygen and minimize brain damage that could result from long dives.   view more (2006-10-10)

Coffee: a cause of neonatal seizures?
Epidemiological observations raised the possibility that coffee was deleterious for newborn babies. For the last ten years the American Food and Drug Administration (FDA) has therefore recommended that pregnant women limit their consumption of coffee.   view more (1999-06-16)

Bedtime Oxygen Tent 'Supercharges' Olympian Athlete
Olympic runner Spencer Duval says a fitness technique he is pioneering with the support of a sports science expert at Staffordshire University could significantly boost the performance of other UK endurance athletes aiming for medals in the Sydney 2000 Games. Spencer, 30, who is set to represent... view more (2000-06-05)

FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.   view more (2007-12-28)

A new chemotherapeutic target for hepatocellular carcinoma
Hepatocellular carcinoma (HCC) is a major health problem worldwide. Currently, the only chance for obtaining a cure in patients with HCC is by either a surgical resection or liver transplantation.   view more (2007-10-25)

Tea, turmeric and the fight against cancer
"There has been a marked increase in cancer research in Leicester in recent years. A great deal of the new work that we undertake here now relates to assessment of novel treatments and prevention and much of the funding for this comes from drug trials for pharmaceutical companies. It is extremely... view more (1999-12-14)

Hearts of male and female rainbow trout are different
The heart is one of the most energy demanding organs of the human body. Its failure to function properly accounts for 600,000 deaths each year. Similarly, the rainbow trout, native to the Pacific Northwest and beloved as a sport- and food fish, requires dynamic and sustained cardiac function to... view more (2007-04-30)

Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.   view more (2008-01-23)
