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...Many still distrust Web sites is yours credible enough?
Many Internet surfers often believe they know a good Web site when they see one. Their intuition is based on a number of surface-level factors. For example, surfers are more likely to trust a site when it a...When doing a good job isn't good enough
You work hard. You've developed a lot of relevant expertise. You've achieved results that are recognized within your company. And you just got fired. Or laid off or RiF'd (reduction in force) or downsized or bought out. Whatever. The bottom line is that that sweet little professional fairy tale of upward and onward has taken a sudden lost-in-a...When technology is not enough, have more picnics
Moveon.org and Howard Deans presidential bid have proven that the internet, when...Californians: Stem cells important enough to go into debt for
Californians have approved putting their state into further debt to fund stem-cell research. In election-day polling, 59 percent of California voters approved Proposition 71, which will provide $3 billion in research grants over the next decade. The proposition, which was endorsed by state Governor Arnold Schwarzenegger in mid-October, establishes a California Institute for Regenerative...AIDS and tobacco are worldwide killers: Is bioscience doing enough to stop them?
MADISON A Wisconsin-born leader in the World Health Organization has laid down an urgent challenge for bioscience researchers: Arrest AIDS and develop an antidote to nicotine addiction, and the planet will be a safer and more productive place. Tom Loftus, the former U.S. ambassador to Norway and the former Speaker of the Wisconsin Assembly, added a sobering global perspective to last we...Kids not getting enough Physical Exercise
Obesity and type 1 diabetes in children, which lead to chronic health problems in adulthood are on the rise. The top issue for paediatricians in the treatment of obesity in children is the amount of physical exercise(PE) that the kids are getting. A recent study has shown that children are not getting nearly enough exercise, making them fall short of the American National guidelines. The...Reducing Number Of Cigarettes Not Enough
Cigarette smoking is the cause of 90 percent of the world’s lung cancer cases. Smokers who substantially reduce // the number of cigarettes they smoke per day are exposed to lower amounts of a potent tobacco carcinogen, or cancer-causing agent. However, the reduction in the amount or concentration of the carcinogen exposure is often temporary and not proportional to the reduction in cigar...Condoms May not be safe Enough
Condoms have been used for prevention of pregnancy for decades and more recently for prevention of // AIDS. However a recent study indicates that wearing a condom during intercourse may not give good enough protection against other sexually transmitted diseases, such as herpes and syphilis. There has been a rise recently in STD's among the young people (15 to 24 yrs) and the news may c...Competitive Sports: Is the heart Sportive Enough?
Sports have been held in high regard since the very old days and it continues to enjoy the privilege even today. None of the other recreation forms have been able to substitute mankind with another alternative. // Very little is known about the risk of sudden death associated with exercise in young competitors. The benefits versus the hazards of sports activity pose a clinical dilemma....
