Researchers discover 'acquired' DNA key to certain bacterial infection

...ult in serious lung infections and is prevalent in emphysema and AIDS patients among others – infects tissue cells or “macrophages” and thus compromises the body’s immunity. Results of the study, led by researchers at Oregon State University, will be published online this week in the Proceedings of the Nation...

Helium helps patients breathe easier

...s caused by smoking and includes the conditions of emphysema and chronic bronchitis. This was the first study to demonstrate that helium-hyperoxia (40 per cent oxygen, 60 per cent helium) improves the exercise tolerance of COPD patients to a greater extent than oxygen alone, which is currently used for tre...

Lungs try to repair damaged elastic fibers

...racterize the regions of the lung showing moderate emphysema and regions showing severe emphysema. They found that new elastin synthesis was initiated in moderately diseased specimens. The researchers did a second study using 10 lungs from end-stage COPD patients who had undergone transplants. Again, they f...

Gene therapy for hereditary lung disease advances

...s. Alpha-1 deficiency can in some patients lead to emphysema and cirrhosis, both progressive diseases that can be fatal. Alpha-1 patients with symptoms of emphysema can be treated through weekly intravenous injections of alpha-1 protein derived from human plasma. T...

New MRI technique shows emphysema in asymptomatic smokers

-A new imaging method has revealed early signs of emphysema in smokers with no external symptoms of the diseas...own that it is possible to measure the severity of emphysema and its progression through time without the radiation exposure of lung CT tests," said Sean B. Fain...

Researches discover gene critical for protection against septic-shock-induced death

...lammatory diseases such as cigarette-smoke-induced emphysema and allergic asthma in mice models. Biswal's team found that the deletion of the Nrf2 gene increased the inflammatory response and caused early death in mice subjected to septic peritonitis or endotoxin shock or both. Mice deficient in Nrf2 gene ex...

Most common lung cancers may begin in newly discovered cells

... to new therapies for other lung diseases, such as emphysema and cystic fibrosis. "We tend to emphasize cancer, because we are in a lab that studies cancer," Bender Kim said. "Identifying stem cells is the biggest part of the story. This population could be very useful for more than cancer." In their paper, t...
