Successful lung cancer surgery not enough to break nicotine dependence in many smokers

...lker said. "Their cancer was discovered largely by accident when they were being examined for other medical conditions, and so was potentially curable by surgery," he said. "More than two-thirds of lung cancer is diagnosed at later stages in people with symptoms, and treatment is much less successful." The...

Gene chip technology shows potential for identifying life-threatening blood infection

...g from surgery, pancreatitis, or trauma from a car accident or fall. Because these patients are also hooked up to IV fluids, catheters or ventilators, they are also prone to bacterial infections, including pneumonia, that can quickly spiral out of control and lead to sepsis. Although both conditions are li...

New research promising for improving brain cell survival after brain injury

...age has wide application and could be given to car accident and assault victims, people undergoing radiotherapy for brain tumours, premature babies that need to be induced, and stroke patients. "While we still have a long way to go before such a drug will be available, this research is a promising step for...

HIV-1's high virulence might be an accident of evolution

...tly responsible for human AIDS--might amount to an accident of evolution, new evidence reveals. A gene function lost during the course of viral evolution predisposed HIV-1 to spur the fatal immune system failures that are the hallmarks of AIDS, researchers report in the June 16, 2006 Cell. AIDS has killed mo...

Unusual mechanism keeps repair protein accurate

...ith regions three and four," Suo says. "Then by accident we learned that this was not just a structural connection, but that it is critical to the protein's ability to replicate DNA with very few mistakes." For this study, Suo and his colleagues wanted to learn how efficiently the new protein made new D...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

...ick thought the difference in number was simply an accident "frozen in time". The University of Bath researchers suggest that the primordial 'doublet' code was read in threes - but with only either the first two 'prefix' or last two 'suffix' pairs of bases being actively read.
