Immunological effectsOne study is reported to have found that women with breast cancer who reported more social activity and social satisfaction had “stronger stimulated TNF-alpha responses". TNF-alpha is a compound produced by immune-system cells, and is “associated with tumour regression and increased survival time for cancer patients". Another study is reported to find increased levels of a particular type of immune-system cell among those women with ovarian cancer who reported a greater amount of social support. The article's author also reports that loneliness has been linked to “low-grade peripheral inflammation" and may therefore be linked to inflammatory diseases, and that lack of social connection or loneliness has also been linked to increased risk of cardiovascular disease.
Helium and exercise help COPD patients breathe easier
Chronic obstructive pulmonary disease is the fourth leading cause of death in Canada. It currently kills more women than breast cancer and health experts project that the disease will become more prevalent as the population ages. Interestingly, Eves' innovative research protocol is already being used in a clinical application by Alberta Health Services Chronic Disease Management Program. "We are always interested in innovations that can help to improve the effectiveness of our health interventions," says Dr. Sandra Delon, PhD, the director of Alberta Health Services' Chronic Disease Management Program. "We've already seen some promising results in this pilot program, so we're very encouraged."

New gold nano-particle to treat breast cancer
Scientists at Brown University have developed a new gold nanoparticle that could help to treat breast cancer, it has been claimed. A twin nanoparticle formed by combining the precious metal with iron oxide may enable cancer fighting drugs to be delivered into the human body without the side effects of medications administered during chemotherapy, Nanowerk News reports. Shouheng Sun, a chemistry professor at the university, told the news source that the aim of the technology is to target tumour cells while ignoring the healthy ones. Start trading in currencies, most happening place to trade"Like a missile, you don't want the anti-cancer drugs to explode everywhere," he was quoted as saying. The technique has destroyed affected cells in up to 80 per cent of cases during laboratory tests and scientists also hope to be able to develop nanoparticles that can release the drug remotely through the use of magnetic heating.
Is Calorie Restriction the Key to a Longer Life?
The xxxx was wide ranging: "significantly decrease the incidence of breast cancer"; or heart disease; or pancreatic cancer; or neurodegenerative diseases; or diabetic diseases; or other cancers; or, the one the media keeps focusing on: CR is the only known intervention that significantly increases the maximal life span of several species. (I posted excerpts and links from several scientific articles on my personal website http://www.nbrhd.net/CR/CR.htm) No other diet came even close to the amount of research on CR/ER. And I had never heard of it. So I looked further. In 1937 CR was shown to increase the maximal (not just the average) life span of rats. This gives an incredible model for studying aging and age related diseases. But then the subject was pretty much dropped until the late 20th century.
Avoiding Incorrect Dosing Of A Common Drug Using Genetic Profiles
Tamoxifen Pharmacogenomics Consortium to determine the effect of CYP2D9 genotypes on outcomes for women taking the breast cancer drug tamoxifen.
"It's really an amazing story," said Altman. "Even though we described what is probably the best ever clinical algorithm for warfarin dosing, this paper shows conclusively that including a patient's genetic information yields a far superior prediction. It's a vast improvement over the guessing game physicians play now."

Wolf Man didn't mind doing nude calendar
Williams is among 40 NRL and football players who stripped down for the McGrath Foundation breast cancer charity calendar, Gods Of Football. Williams also features on the front cover of a new behind the scenes DVD, to be released on Thursday, posing in just a pair of white briefs. The DVD offers a revealing look into the calendar shoot. It features Dragons player Matt Cooper and Manly's Brett Stewart from the NRL, and Hawthorn's Luke Hodge and Essendon's Andrew Welsh from the AFL. Asked if he would pose naked again, Williams said: "Yes, I certainly would." He also said he liked being a gay icon, and joked that he'd turn gay for his Sea Eagles teammate Heath L'estrange. "I like my gay fans and I'm thankful for their support - we need all the support we can get," he said.
NB assumes oversight of hospital labs after public inquiry
An audit of Menon's work last year found 18 per cent of 227 breast and prostate cancer reports were incomplete and three per cent were incorrect. Menon, who is now in his 70s, has maintained his work was not as flawed as the inquiry was told, and he portrayed himself as the victim of a hospital administration that was out to get him. The government said Friday it has also implemented improvements to quality assurance and it is consulting on amendments to the Medical Act so that the investigative, disciplinary, and audit authority of the provincial college of physicians and surgeons can be expanded. "Judge Creaghan's comprehensive report has been very useful to this government in our efforts to ensure that patients throughout the province receive the highest quality pathology services in our health-care system," said Murphy.
