New test to detect rare proteins in blood

...eveloping tests for other cancer markers including lung cancer and colon cancer. All proteins tested so far with FACTT have been detected with an over 1000-fold higher sensitivity compared to current technologies. The researchers say this points to FACTT's broad applicability and compatibility with curre...

DNA end caps may lead to cancer treatments, UT Southwestern researchers report

...anti-telomerase drug that helps slow the spread of lung cancer cells in mice. The drug is being tested in humans to see if it's safe. The researchers say that any anti-telomerase drug would not be used alone to treat cancer. Rather, it would be used in conjunction with more traditional treatments, such ...

Study may help slay 'Yellow Monster'

Chemical in many air fresheners may reduce lung function

...robenzene (1,4 DCB) may cause modest reductions in lung function. "Even a small reduction in lung function may indicate some harm to the lungs," said NIEHS researcher Stephanie London, M.D., lead in...

DNA: Bacteria's survival ration

... cystic fibrosis is suspected of feeding on DNA in lung tissue, Finkel said. Biofilms, which have been linked to chronic infections, also may harbor nutritionally competent germs. If researchers succeeded in turning off nutritional competence in such pathogens, as Finkel did in E. coli, the advance might...

Failure of 'scout cells' may lead to cancer in transplant patients

...atients and in up to 20 percent of bone marrow and lung transplant patients. The disease usually arises within six months to a year after transplantation, and it can have a 70- to 80-percent mortality rate. The study by VanBuskirk and her colleagues examines two types of immune cells: cells that act as...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...T/CT images (with FDG) are accurate for evaluating lung and colorectal cancer; however, they lack the anatomic information that can be provided by 3-D images from a multidetector CT scan. Even so, with 3-D CT scans, small and flat lesions in the lungs and colon are difficult to see or characterize, said Q...
