Secondhand smoke damages lungs, MRIs show

It's not a smoking gun, but it's smoking-related, and it's there in bright medical images: evidence of microscopic structural damage deep in the lungs, caused by secondhand cigarette smoke. For the first time, researchers have identified lung injury to nonsmokers that was long suspected, but not previously detectable with medical imaging tools. The researchers suggest that their findings may strengthen public health efforts to restrict secondhand smoke.

2. Cells in the lung clear the air to prevent lung damage
   03-01-2007 · EurekAlert!
   Air pollution and tobacco smoke contain oxidants that when inhaled can cause damage to the lungs and contribute to diseases such as asthma and chronic obstructive pulmonary disease (COPD). In a study that appears in the March issue of the Journal of Clinical Investigation, researchers from the Harvard School of Public Health, Boston, identify a new mechanism by which mice are protected against inhaled oxidants.

   10-16-2006 · EurekAlert!
   Levels of heme oxygenase-1 (HO-1), an antioxidant that protects against reactive oxygen species (damaging oxygen molecules that cause direct tissue injury), become elevated in the lungs of chronic silicosis patients and could represent a new treatment approach for the disease.These results appear in the second issue for October 2006 of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.

   05-02-2007 · EurekAlert!
   Scientists have found that sperm from diabetic men have greater levels of DNA damage than sperm from men who do not have the disease. They warn that such DNA damage might affect a man's fertility. The research is published in the journal, Human Reproduction.

6. Gene variations directly link inflammation to an increased risk for lung cancer
   07-03-2007 · EurekAlert!
   Variations in two genes related to inflammation may be a major risk factor for developing lung cancer, according to a team of scientists from the National Cancer Institute and the University of Texas M. D. Anderson Cancer Center. The effect of these genes is especially strong among heavy smokers, suggesting that the inflammatory response is important in modulating the damage caused by tobacco smoke.

   Researchers at the Royal Veterinary College, London, have made a significant breakthrough in their understanding of how infection of the uterus damages fertility in cows. Their findings, which show that common uterine infections can damage the ovaries, may provide insights into how to treat infections such as chlamydia in humans.

8. Cigarettes leave deadly path by purging protective genes
   01-23-2008 · EurekAlert!
   A University of Rochester scientist discovered that the toxins in cigarette smoke wipe out a gene that plays a vital role in protecting the body from the effects of premature aging. Without this gene we not only lose a bit of youthfulness -- but the lungs are left open to destructive inflammation and diseases such as chronic obstructive pulmonary disease and lung cancer.

   Researchers at Johns Hopkins have discovered the first genetic evidence that secondhand smoke can worsen lung disease. The report in this week's Journal of the American Medical Association describes one gene variation that can weaken lung function as well as shorten the lifespan of those affected by cystic fibrosis and also are exposed to secondhand smoke.

10. Nicotine Receptors On Kidneys May Speed Kidney Damage
    10-10-2006 · ScienceDaily
    Scientists say they have found nicotine receptors on kidney cells that may link nicotine to accelerated kidney damage in cigarette smokers. Their research -- presented at the American Heart Association's 60th Annual Fall Conference of the Council for High Blood Pressure Research -- also identifies nicotine as the component of cigarette smoke that damages the kidneys.
