ScienceDaily (May 22, 2009) - A new article in the journal Risk Analysis assessed various ways in which aerosol transmission of the flu, a central mode of diffusion which involves breathing droplets in the air, can be reduced. Results show that face protection is a key infection control measure for influenza and can thus affect how people should try to protect themselves from the swine flu. Lawrence M. Wein, Ph.D., and Michael P. Atkinson of Stanford University constructed a mathematical model of aerosol transmission of the flu to explore infection control measures in the home. Their model predicted that the use of face protection including N95 respirators (these fit tight around the face and are often worn by construction workers) and surgical masks (these fit looser around the face and are often worn by dental hygienists) are effective in preventing the flu. The filters in surgical masks keep out 98 percent of the virus. Also, only 30 percent of the benefits of the respirators and masks are achieved if they are used only after an infected person develops symptoms. "Our research aids in the understanding of the efficacy of infection control measures for influenza, and provides a framework about the routes of transmission," the authors conclude. This timely article has the potential to impact current efforts and recommendations to control the so-called swine flu by international, national and local governments in perspective. This study is published in the journal Risk Analysis.

March 9, 2009 -- Red or white wine with dinner? A new study suggests a woman's wine choice should be based on personal preference rather than any hope that a wine's color may affect its breast cancer-fighting ability. "We found no difference between red or white wine in relation to breast cancer risk. Neither appears to have any benefits," researcher Polly Newcomb, PhD, MPH, head of the Cancer Prevention Program at the Fred Hutchinson Cancer Research Center in Seattle, says in a news release.

dbroadwa I had a case of macular degeneration 7 years ago. For about three months I couldn't make out any features on a person's face from across a room with my right eye. My eye doc told me there was no cure. I contacted a person who worked at a holistic health college and she told me it sounded like I was dangerously deficient in zinc and selenium. She also sent me a chinese herbal formula called Celosia 10, some died red berries and told me to pick up bilberry supplement. I started taking these five supplements and in a week to ten days my eyesight was back to normal. On the next visit to the eye doc he was reading my file as he came in and asked if there were any changes since my last visit. I said 'as a matter of fact, yes'. He wrote down all the supplements I'd taken and I later printed out all the info off the containers and dropped it off at his office. He called to tell me that I was taking too much zinc and it could do liver damage, but I'd stopped taking it by then. Three times since, I've started to get the symptoms back and took at least some of these things with the same results. There are two types of MD, and I think only one responds to this approach. bpfsa Spinach truly is a wonderful vegetable, full of healthy properties. There's a website at http://www.spinachwords.com that shows how spinach is a multi-vitamin, multi-mineral, multi-amino, multi-phytonutrient powerhouse. There's alot more to spinach than just lutein and zexanthin and it is beneficial for much more than just your vision. It is great for your heart, for cancer prevention, for maternal & fetal health & development, it boosts your natural SPF levels in your skin, it wards of memory loss, dementia and other signs of ageing, and it is good for strong bones, too. Popeye was right - except maybe about eating a highly processed, canned product instead of fresh spinach.

Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D. Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.
