Bird 'breathalyzer' helps assess migratory diet

KINGSTON, R.I. -- November 24, 2003 -- While breathalyzers help police crack down on drunk driving, a similar new device is helping a University of Rhode Island graduate student analyze the dietary changes of migrating songbirds. ...

Ultra-low oxygen could have triggered die-offs, spurred bird breathing system

Recent evidence suggests that oxygen levels were suppressed worldwide 175 million to 275 million years ago and fell to precipitously low levels compared with today's atmosphere, low enough to make breathing the air at sea level feel like respiration at high altitude.... ... Now, a University of Washington paleontologist theorizes that low oxygen and repeated short but substantial temperature incr...

Nasal contribution to breathing with exercise: The effect of race and gender

(Bethesda, MD) The mode of breathing -- via the mouth (oral) or the nose (nasal) -- is an important determinant of a deposited dose of inhaled particles and gases to the lungs. The nose can act as an effective filter to prevent penetration of particles and gases to the lower respiratory tract. Gases that are very water soluble or reactive (such as ozone) can be extracted in the nose by as much...

Rb2 gene may play role in determining effectiveness of drug therapies against breat cancer

The tumor suppressing gene pRb2/p130 may play a significant role in determining the effectiveness of drug therapies against breast cancer in women, according to a study by researchers at Temple University's Sbarro Institute for Cancer Research and Molecular Medicine. ... The study, "pRb2/p130-E2F4/5-HDAC1-SUV39H1-p300 and pRb2/p130-E2F4/5-HDAC1-SUV39H1-DNMT1 Multimolecular Complexes Mediate the T...

Genomic study breathes new life into asthma research

Research published in this month's Genome Biology has identified 149 genes that may be involved in the development of asthma. This research, the first of its kind, is exciting, as 52 of these genes were previously unknown.

Virtual lung models every breath you take - and its impact

RICHLAND, Wash. - A virtual lung model developed at the Department of Energys Pacific Northwest National Laboratory may help predict the impact of pollutants on respiratory systems and provide new insights into asthma, a condition afflicting 15 million American adults, as well as other pulmonary diseases.... The computer model, called the virtual respiratory tract, provides an unprecedented,...

UCLA neurobiologists identify brain cells that control breathing

For the first time, UCLA scientists have identified the small group of brain cells believed to originate breathing in mammals. Reported in the September issue of Nature Neuroscience, their discovery could lead researchers to new approaches to addressing serious health problems, such as sleep apnea and sudden infant death syndrome....... In a previous study, the UCLA team had pinpointed a specifi...

Study: breath test effective in showing patients who should get less cancer drug

. . Battling cancer is traumatic enough without worrying about whether chemotherapy will prove toxic, but that's the added risk facing a minority of cancer patients.. Standard doses of chemotherapy -- often effective in treating various solid tumors -- sometimes kill people whose livers cannot clear the drug at the normal rate. Doctors can't tell beforehand which patients might have trouble wi...

Studies of marine mammals indicate a "breathtaking" ability to dive to great depths
