Smoking and solid fuel use in homes cause millions of deaths
sea-maid submitted, created time 1 day 15 hours (esciencenews.com)
If current levels of smoking and biomass and coal fuel use in homes continues, between 2003 and 2033 there will be an estimated 65 million deaths from chronic obstructive pulmonary disease (COPD) and 18 million deaths from lung cancer in China, accounting for 19% and 5% of all deaths in that country during this period. Researchers at the Harvard School of Public Health (HSPH) predict that the combined effects of these two major factors alone will be responsible for more than 80% of COPD deaths and 75% of lung cancer deaths in China over a thirty-year period
Gene therapy tool would target free radicals

Gene therapy has been touted as a possible way to cure genetic diseases, but new research suggests that it could also fight the wear and tear that leads to cardiovascular diseases.
ScienceNews reports:
"To work within this delicate balance, researchers in Finland have developed a way to insert into human cells free radical–fighting genes that only get switched on when free radical concentrations are high. That way, the genes could stave off the worst effects of free radicals without inhibiting the molecules’ useful functions, the researchers report in the September Gene Therapy."
Do light cigarettes deliver less nicotine to the brain than regular cigarettes?

For decades now, cigarette makers have marketed so-called light cigarettes — which contain less nicotine than regular smokes — with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain despite having a lower overall nicotine content.

The path from the lab to the marketplace for genetically modified cows, pigs and chickens has been clearly spelled out for the first time.
On September 18, the U.S. Food and Drug Administration released a draft of regulations for approving engineered animals for commercial use. The draft is freely available and open for public comment until November 18...
Baby Bottle Chemical Linked to Disease

The first major epidemiological study of bisphenol A, a common ingredient in baby bottles and drink containers, suggests that relatively higher doses of the chemical double the risk of diabetes and cardiovascular disease. The finding comes as a scientific review panel meets here to begin evaluating the U.S. Food and Drug Administration's (FDA's) draft assessment of the health risks of the compound

The debate over the safety of a chemical ubiquitous in the lives of Americans took center stage at a scientific hearing of the U.S. Food and Drug Administration on Tuesday as federal officials, scientists and health advocates gave vastly different assessments of the effects of exposure to bisphenol A...
Fat Molecule Fights Weight Gain

Rearchers have isolated a fat molecule in mice that prevents the animals from storing more fat. The discovery could open a new front in the battle against the bulge if the molecule has the same effect in humans.
The word "fat" typically evokes the image of clogged arteries or cellulite jiggling on a thigh. But fat has a good side, too. Fat cells make up adipose tissue, which helps regulate insulin levels and breaks down dietary fat for energy. This breakdown is accomplished via proteins in fat cells called fatty acidinding proteins

Surgical interventions for many obese children suffering from obstructive sleep apnea may not cure the problem, says new research presented at the 2008 American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL. Obese children are at increased risk for developing obstructive sleep apnea (OSA), a sleep disorder that is associated with a decreased quality of life as well as behavioral, neurocognitive, cardiovascular, metabolic, endocrine, and psychiatric complications
