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

A new study has found that close to half of 154 smokers who had surgery to remove early stage lung cancer picked up a cigarette again within 12 months of their potentially curative operation, and more than one-third were smoking at the one year mark. Sixty percent of patients who started smoking again did so within two months of surgery. The study, led by researchers at Washington Univers...

Gene therapy to lower blood pressure just enough

A newly developed virus that introduces a blood pressure-lowering gene into cells and enables that gene to maintain blood pressure at healthy levels for four months promises to take gene therapy for the disorder a step closer to reality, said researchers at Baylor College of Medicine in a report released online in the Proceedings of the National Academy of Sciences. "High blood pressure is...

A little telomerase isn't enough

With seed money from Johns Hopkins Institute of Cell Engineering, a Johns Hopkins geneticist and her team have discovered a critical link between the health of stem cells and the length of the chromosome ends within them. Chromosome ends, or telomeres, are repetitive stretches of DNA that protect chromosomes in much the same way as plastic tips on shoelaces prevent the fabric from fraying....

Medical experts: US unlikely to have enough vaccines to stop avian flu

A group of medical experts who attended a national avian flu conference last fall believe there is little chance the United States will be able to manufacture and stockpile enough vaccine or antiviral medication to stop a bird flu pandemic should the virus mutate into a form that can be spread easily from human to human, according to a survey led by researchers at Carnegie Mellon University. The...

Heart has enough oxygen to survive hypothermia, CPR crucial

Researchers from Norway may have ruled out insufficient oxygen supply to the heart as the critical variable in whether a mammal's heart survives while in a hypothermic state. Writing in the July issue of the American Journal of Physiology-Heart and Circulatory Physiology, researchers found no significant difference in the amount of oxygen available to the heart between rats exposed to one...

Walking not enough for significant exercise benefits

Walking is a popular form of exercise, but may not be enough to experience significant health benefits, a University of Alberta study shows. "Generally, low-intensity activity such as walking alone is not likely going to give anybody marked health benefits compared to programs that occasionally elevate the intensity," said Dr. Vicki Harber, lead author on the Health First study, which was...

Increase in drug development for killer diseases is not enough

A recent report shows that drug development for killer diseases such as HIV/AIDS, TB, Malaria, Chagas and Sleeping Sickness has increased in recent years. This is despite the fact that these diseases mainly affect the poor in developing countries and development of treatments is inhibitive due to lack of economic demand. Researchers argue that the rate of development of drugs (and of some vaccine...
