Заразяване Причинител е вирусът на птичия грип (ПГ). Всички ПГ-вируси принадлежат към родa на грипния вирус А от семейство Orthomyxoviridae и са сегментирани РНК вируси с отрицателна верига. Птичият грип се разпространява по въздуха и чрез изпражненията. Дивите птици често изпълняват ролята на резистентни носители, предавайки го на по-чувствителни домашни породи.

Filed under: Breast Cancer , Celebrity cancer diagnosis , Television , Daily news , Surgery ABC's Good Morning America co-anchor Robin Roberts is at home resting after a successful surgery for breast cancer. Pathology reports will take some time to pocess, but when more information is available, the public will be updated, says a Good Morning America spokesperson. Roberts, 46, told her story recently in an e-mail. I never thought I'd be writing this. ... I have breast cancer," writes Roberts. It all started a few weeks ago. We had gotten the news that our dear colleague and friend Joel Siegel had passed away and we began preparing for our special tribute show for him. I did a piece about Joel's courageous battle with cancer, reporting on the way my friend had lived his life and been such a successful advocate for the importance of early cancer screenings.

Filed under: Skin Cancer , Daily news Last Tuesday night, I watched Greta Van Susteren of Fox News' On The Record as she interviewed Brittany Lietz, Miss Maryland 2006. Greta asked Brittany what her Miss Maryland job entails. Brittany told Greta her full-time job is to represent her platform -- skin cancer. Brittany didn't choose just any topic for her platform. She chose one that is entirely personal. Skin cancer has left more than 20 scars on Brittany's body. One, on her back, marks the site where a stage two melanoma was removed when she was just 19 years old. It presented as a mole, a little smaller than a nickel, she says. In all likelihood, the cancer was caused by two years of tanning bed use. Brittany says she probably tanned every day for two years. Her pursuit of bronzed skin began when she was 17 and wanted a tan for her prom. It ended after doctors told her she had cancer. Brittany's cancer was caught early and both she and her dermatologist believe her prognosis is good. Between Brittany's vigilant monitoring of her own skin and her every-three-month doctor visits, anything suspicious that pops up will surely be detected. Greta asked Brittany's dermatologist what it is about skin cancer that we just don't get. Here is what she said: UV radiation is a carcinogen .

Filed under: All Cancers , Opinion When I read something powerful -- a quote, a story, a reflection -- I write it down or cut it out or make a copy of it and drop it into a file folder I've titled inspiration. This file, among others, has been on many a moving van and has traveled with me all over the East coast, from city to city, house to house. And every once in a while, when I need a lift, this is my go-to file -- I go to it, pluck something out, and refresh my mind and spirit. This file has been with me since at least 1997 -- the date on a photo-copied Ann Landers column I have sitting before me. It's 10 years old, but there's nothing dated about the words printed on this single sheet of paper. They are as touching and moving and relevant now as they were when I first read them. They may be even more meaningful today, because of the thread of cancer that is now woven throughout my days. These are life lessons, offered by a publisher of the Mount Pleasant News in Iowa, for students about to graduate from high school. They go like this: Dear Graduates: There is the kind of education you get in school and the kind you get afterward. Both are important. Put them together, and you have wisdom. The trouble is, life is generally half over before you figure out what is going on. Graduating seniors can save 25 years of trial, error, and hard knocks by memorizing the lessons of life listed below. On the average, you learn about one big lesson per year after you leave high school. In really tough years, you learn two or three. Some years, you don't learn anything. After 40, you forget things and have to learn them again. Some of this information is borrowed. Some is stolen. Some may even be original, but that's doubtful. It's pretty hard to be original in a world as old as this one. 25 Things You'll Need To Know After High School 1. Don't sweat the small stuff, and remember, most stuff is small. 2. The most boring word in any language is "I." 3. Nobody is indispensable, especially you. 4. Life is full of surprises. Just say "never" and you'll see. 5. People are more important than things. 6. Persistence will get you almost anything eventually. 7. Nobody can make you happy. Most folks are as happy as they make up their minds to be. 8. There's so much bad in the best of us and so much good in the worst of us that it doesn't behoove any of us to talk about the rest of us. 9. Live by what you trust, not by what you fear. 10. Character counts. Family matters. 11. Eating out with small children isn't worth it, even if someone else is paying. 12. If you wait to have kids until you can afford them, you probably never will. 13. Baby kittens don't begin to open their eyes for six weeks after birth. Men generally take 26 years. 14. The world would run a lot smoother if more men knew how to dance. 15. Television ruins more minds than drugs. 16. Sometimes there is more to gain in being wrong than right. 17. Life is so much simpler when you tell the truth. 18. People who do the world's real work don't usually wear neckties. 19. A good joke beats a pill for a lot of ailments. 20. There are no substitutes for fresh air, sunshine, and exercise. 21. A smile is the cheapest way to improve your looks, even if your teeth are crooked. 22. May you live life so there is standing room only at your funeral. 23. Mothers always know best, but sometimes fathers know too. 24. Forgive your friends and your enemies. You're all only human. 25. If you don't do anything else in life, love someone and let someone love you. Permalink     Email this     Linking Blogs     Comments

Filed under: Colon and Rectal Cancer , Politics , Daily news , Celebrity news , Cancer Survivors , Surgery White House press secretary and colon cancer survivor Tony Snow asks the public to refrain from jumping to conclusions regarding the surgery he will have on Monday to remove a growth from his lower abdomen. Blood tests and a CAT scan of the growth show no presence of cancer, he reports. But still, he and doctors are proceeding cautiously due to his history.

Making a small change in the outer coating of the lethal 1918 flu virus was enough to stop it from spreading — a discovery that may help scientists monitor today’s bird flu and other influenza strains for signs of the next pandemic. The 1918 pandemic was triggered by a bird virus that mutated into one that [...]

Leading scientists in Hong Kong have found that the H5N1 bird flu virus can infect cells in the upper airway of humans and need not penetrate deep in the lungs to cause infection. A study by scientists based in the United States in 2006 suggested that H5N1 could not infect people easily because it had to [...]

Could some people have a little immunity to the H5N1 bird flu virus? One study in mice published Monday suggests it is, in theory, possible. They found mice inoculated with a human virus known as H1N1 were less likely to die when they were infected with a little bit of H5N1 — although this protection went [...]

Similarity of H5N1 strains indicates transmission between poultry Tests on H5N1 bird flu viruses found in Britain and Hungary showed they are “essentially identical” and the most likely transmission route was from poultry to poultry, Britain said on Tuesday. The government said in a statement it had not found any evidence of illegal or unsafe movements of [...]
