TIME Examines HIV Vaccine Efforts TIME features a profile on David Ho, director of the Aaron Diamond AIDS Research Center (ADARC) in New York City, who is currently working on a novel HIV vaccine. Ho "now believes that a traditional shot, one that relies on snippets of a virus to both awaken and prod the immune system to churn out antibodies, may not be the best way to fight HIV. Rather than expecting the body to do all the work of first recognizing then mounting an attack against the virus, why not just present the body with a ready-made arsenal of antibodies that can home in on HIV?, " the magazine writes. The article details Ho's theory, highlights how his research helped to shape current HIV drug regimens and tracks the challenges scientists have faced in developing an HIV vaccine in recent years (Park, 1/25).

Sweating Out The Cravings

It's been 18 excruciating hours since you last had one. You're irritable, stressed out, and the cravings are intense. There is only one thing you can think about firing up - and it isn't your treadmill. But that's exactly what University of Western Ontario researchers have been hard at work trying to convince smokers to do. Dr. Harry Prapavessis, Director of Western's new Exercise and Health Psychology Laboratory, and his team (Dr. Anita Cramp, Dr. Mary Jung and Therese Harper) are getting smokers to make the switch from lighting up to lacing up in an effort to help beat their cravings and kick their smoking habit - for good. Dr. Harry Prapavessis and his team have shown that supervised exercise in addition to pharmacological agents like nicotine replacement therapy (NRT) helps smoking cessation, improves physical fitness, and delays weight gain in women smokers.

Electronic Cigarettes: Are They Safe?

Two experts on today say that further research is needed before consumers can be reassured that electronic cigarettes (also known as e-cigarettes) are safe. "Our knowledge on the acute and long term effects of e-cigarette use is, at best, very limited", say Andreas Flouris and Dimitris Oikonomou, from the Institute of Human Performance and Rehabilitation in Greece. Interest in alternative smoking products is augmenting since anti-smoking policies are becoming more widespread. Electronic cigarettes or e-cigarettes are one of the most newly introduced products on the market. These are battery operated devices that allow users to inhale a nicotine vapor.

Tobacco Smoke Causes Inflammation, Promotes Cancer Growth

Repeated exposure to tobacco smoke makes lung cancer much worse, and one reason is that it steps up inflammation in the lung. Scientists at the University of California, San Diego School of Medicine have found that mice with early lung cancer lesions that were repeatedly exposed to tobacco smoke developed larger tumors - and developed tumors more quickly - than unexposed animals. The key contributing factor was lung tissue inflammation. The results of their study, to be published January 19 in the journal Cancer Cell, provide definitive evidence for the role of lung inflammation brought on by chronic exposure to tobacco smoke in promoting lung cancer growth.

Molecular Link Between Tobacco Carcinogen And Cancer

A team of researchers, led by Yi-Ching Wang, at National Cheng Kung University, Taiwan, Republic of China, has uncovered a potential mechanism by which the tobacco-specific carcinogen NNK promotes lung tumor formation and development. Specifically, they suggest that NNK induces the accumulation of a protein known as DNMT1 in the nucleus and that this protein silences genes that suppress tumor formation. The authors generate several lines of evidence to support their suggested mechanism, one of which is the observation that DNMT1 accumulates in both lung adenomas from NNK-treated mice and tumors from lung cancer patients that were smokers. Of clinical relevance, DNMT1 overexpression in lung cancer patients who smoked continuously correlated with poor prognosis.

Court Affirms Electronic Cigarettes As Tobacco Products, Not Drugs

Smoking Everywhere, Inc. announced that the U.S. District Court for the District of Columbia ruled in its favor Thursday, affirming that the company's electronic cigarette product is legally considered a tobacco product and cannot be regulated by the U.S. Food and Drug Administration (FDA) as a drug. Smoking Everywhere filed a lawsuit against the FDA in April 2009, claiming that inbound shipments of its products from overseas manufacturers had been denied entry into the United States, or had otherwise been detained, by order of the FDA on the ground that electronic cigarettes are an unapproved drug-device combination under the Food, Drug, and Cosmetic Act (FDCA).

China To Ban Smoking In 7 Cities: Pilot Project

Seven cities in China, the largest consumer of tobacco worldwide, are taking steps to ban smoking in workplaces and public venues: under current legislation smoking is allowed in certain public places, but experts say enforcement is poor.

Speaking at the launch of the joint project on Friday, Wang Yu, director of China's CDC told the media that: "Only with the support of the pilot cities' municipal governments and legislatures can the people there finally enjoy smoke-free environments.

Federal Court Halts FDA Efforts To Detain E-Cigarettes

Matt Salmon, president of the Electronic Cigarette Association (ECA), today applauded a federal court's decision yesterday to halt the Food and Drug Administration's (FDA) regulatory overreaching by blocking adult consumers' access to electronic cigarettes. "This is a major victory for consumers, common sense, and electronic cigarette companies, " said Salmon. "It is a significant step in the right direction for the electronic cigarette industry and finally gives the long-overdue recognition of its products as viable alternatives to traditional cigarettes." Yesterday, the U.S. District Court for the District of Columbia issued a decision granting a preliminary injunction seeking to prevent the FDA from detaining or refusing U.
