Aided by next-generation DNA sequencing technology, an international team of researchers has gained insights into how more than 60 carcinogens associated with cigarette smoke bind to and chemically modify human DNA, ultimately leading to cancer-causing genetic mutations. http://www.physorg.com/news180191982.html Medicine & Health Wed, 16 Dec 2009 13:21:09 EST news180191982 Asthmatic smokers may be able to reverse some of the damage to their lungs that exacerbates asthmatic symptoms just by putting down their cigarettes, according to research out of the University of Groningen in the Netherlands. http://www.physorg.com/news179379532.html Medicine & Health Mon, 07 Dec 2009 03:50:01 EST news179379532 Researchers at the UC San Diego School of Medicine have pinpointed a mechanism that may help explain how chromosomal translocations - the supposedly random shuffling of large chunks of DNA that frequently lead to cancer - aren't so random after all. They have developed a model of such chromosomal mix-ups in prostate cancer which indicates that the male sex hormone (androgen) receptor unexpectedly plays a key role in driving specific translocations in the development of cancer. http://www.physorg.com/news179065247.html Medicine & Health Thu, 03 Dec 2009 12:21:27 EST news179065247 A new study on the smokeless tobacco product called moist snuff - placed between lip and gum - has led scientists in Minnesota to urge the tobacco industry to change manufacturing practices to reduce snuff's content of carcinogens.

The study, published this month in the journal Circulation, showed that tobacco smoke leads to accelerated immune system rejection of the transplanted heart, heightened vascular inflammation and increased oxidative stress, and a reduction in the transplanted organ's chance of survival by 33-57 percent. http://www.physorg.com/news178310182.html Medicine & Health Tue, 24 Nov 2009 18:38:10 EST news178310182 Children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults, according to new research from Butler Hospital and Brown University. http://www.physorg.com/news177951030.html Medicine & Health Fri, 20 Nov 2009 14:51:27 EST news177951030 A recent study determined there is a significant risk of seizure for individuals who currently smoke cigarettes. Boston-based researchers from Brigham and Women's Hospital and Harvard Medical School also found that long-term, moderate intake of caffeine or alcohol does not increase the chance of having a seizure or developing epilepsy. This is the first prospective study to examine the potential risks associated with cigarette smoking, caffeine intake, and alcohol consumption as they independently relate to epilepsy. Full findings of this study are currently available online and will appear in the February 2010 issue of Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy. http://www.physorg.com/news177763536.html Medicine & Health Wed, 18 Nov 2009 11:20:02 EST news177763536 Risk of bladder cancer for smokers has increased since the mid-1990s, with a risk progressively increasing to a level five times higher among current smokers in New Hampshire than that among nonsmokers in 2001-2004, according to a new study published online November 16 in the Journal of the National Cancer Institute. Furthermore, researchers found that among individuals who smoked the same total number of cigarettes over their lifetime, smoking fewer cigarettes per day for more years may be more harmful than smoking more cigarettes per day for fewer years. http://www.physorg.com/news177620245.html Medicine & Health Mon, 16 Nov 2009 22:30:01 EST news177620245 As if there weren't enough reasons to stop smoking, a team of researchers at the Research Institute of the McGill University Health Centre (RI-MUHC) have just found another. A study led by Dr. Christian A Pineau, Co-Director of the Lupus and Vasculitis clinic at the MUHC, has clearly linked skin damage and rashes to smoking in people with systemic lupus erythematosus (SLE).

An anonymous survey of over 700 home healthcare RNs employed in New York City provided the most complete assessment of homecare hazardous household conditions to date. The most common hazardous conditions found in households were environmental and physical hazards, including animal hair, cigarette smoke, excessive dust, and mold/dampness. Physical hazards, such as loose rugs, were also common. http://www.physorg.com/news155387948.html Medicine & Health Wed, 04 Mar 2009 11:20:10 EST news155387948 Although the immune system is designed to protect the body from harm, it may actually worsen one of the most difficult-to-treat respiratory diseases: chronic obstructive pulmonary disorder (COPD), according to new University of Cincinnati (UC) research. http://www.physorg.com/news153422895.html Medicine & Health Mon, 09 Feb 2009 17:29:33 EST news153422895
