Gene Therapy For Parkinson's Disease Moves Forward In Animals

... John Paul II was recently hospitalized because of breathing problems that were complicated by his advancing Parkinson's disease. “The use of GDNF as an approach against Parkinson's disease has truly had some ups and downs,?said J. William Langston, M.D., scientific director and chief executive officer of The...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

New studies suggest airborne SARS transmission is possible

...the virus from an infected patient to the air, via breathing or coughing. During the outbreak in Toronto hospitals, health care workers became infected with the virus despite observance of strict infection control precautions. The investigators wondered whether environmental contamination of hospital air or s...

New research indicates a 'troubled' greenhouse is brewing

...igh atmospheric carbon dioxide from studies of the breathing pores in fossil leaves," he explains. "At that time, Wyoming warmed from a mean annual temperature of some 55 degrees to a summer-like 65 degrees Fahrenheit. Rainfall in Utah jumped from 16 inches per year to 26 inches per year. As a result, sagebrus...

Atmosphere may cleanse itself better than previously thought

...hat could be giving our pollution-weary lungs more breathing room." Francisco's research, which he performed at the University of California, San Diego with two of that institution's scientists, lead author Amitabha Sinha and graduate student Jamie Matthews, appears in this week's (May 9?3) online early editi...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...om in vitro studies may not be relevant to living, breathing organisms. The Salk scientists' findings are published in this week's online early edition of the journal Proceedings of the National Academy of Sciences. Until now, scientists had assumed, based on studies in cultured cells, that p53 had to be modi...

How exactly does the brain control breathing?

An understanding of exactly how the brain controls breathing is fundamental to the treatment of respiratory disorders. We know that breathing is an automatic rhythmic process that persists without conscious effort whether we are awake or asle...

Bacterial genome sheds light on synthesizing cancer-fighting compounds

Sea squirts around the world are breathing a sigh of relief, as they no longer run the risk of being harvested for their natural disease-fighting substances. Scientists recently discovered that the bacterium Prochloron didemnii, which lives symbiotically inside the sea squirt, actually produc...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...comparable to those of a smoking human mother. The breathing abilities and lung development of these monkeys was then compared with monkeys born to mothers who had received both nicotine and vitamin C doses during pregnancy. A third group of baby monkeys that did not receive either nicotine or vitamin C during...

Researchers identify genes associated with lung transplant rejection

It was conducted by reviewing the medical literature and calculating, based on animal studies, the amount of manganese people would absorb by showering 10 minutes a day. Because manganese is monitored in public w...
