Small Business Owners Deliver Mixed Messages To Capitol Hill
As more specific legislative language emerges on health care, "small business organizations are encouraging members to make their views known through e-mails, letters, phone calls and personal visits" to members of Congress, but "the message is a decidedly mixed one," Kaiser Health News reports. "Small business, a powerful constituency in every congressional district, no longer speaks with one voice on health care. Many of the bigger and more powerful groups that represent small businesses, including the National Federation of Independent Business (NFIB) and the U.S. Chamber of Commerce, have long been allied with Republicans and are lobbying hard against the public option and the employer mandate." But newer, less conservative groups, including the Main Street Alliance, are advocating for those same hot button issues.

Physicians Wait For Health IT Guidelines, Officials Want 'Every Doctor's Office' Online
Physicians are still waiting for clear cut rules for how they must use health information technology in order to be eligible for economic stimulus-funded incentives, American Medical News, a publication of the American Medical Association, reports. The publication notes that (the $2 billion) "incentive money will directly address the use of EMRs, not the purchase of the systems." The sole, ambiguous requirement - that doctors must make "meaningful use" of the technology - will be defined by year"s end. But, industry consultants say doctors can and should get a head start on the governments expectation that they"ll be able to adopt the technology by 2011. Practices can expect requirements to include e-prescribing, certification through a government-approved certifying body, quality reporting, and the ability of one system to exchange information with others (Dolan, 6/15).

Gastrin Plays Significant Role In Helicobacter-Induced Stomach Cancer
A group led by Columbia University Medical Center"s Timothy Wang, M.D., has studied the role of Helicobacter infection in the development of stomach cancer and found that the hormone gastrin, which stimulates secretion of gastric acid, plays a key role in the development of Helicobacter-induced stomach cancer, and may have distinct effects on carcinogenesis in different parts of the stomach.

Ageing Brains Show Great Promise For Rejuvenation

UQ neuroscientists have, for the first time, been able to demonstrate that moderate exercise significantly increases the number of neural stem cells in the ageing brain. In research published in Stem Cells, Dr Daniel Blackmore and his colleagues at the Queensland Brain Institute (QBI) have shown that moderate exercise directly increases the number of stem cells in the ageing brain. Despite the conventional wisdom that we only have a set number of neurons or brain cells, neuroscientists have known for some time that, in healthy brains, the creation of new neurons is an ongoing and lifelong mechanism. However, it has also been known for more than a decade that the number of new neurons we produce slowly declines with age. According to QBI neuroscientist Dr Blackmore, researchers are interested in finding ways to stimulate the production of neurons to negate any decline brought about by age or disease. "Our findings suggest that moderate exercise, from early to late in life, can have a very positive effect," Dr Blackmore said. In controlled models of ageing, the number of neural stem cells produced by animals participating in voluntary exercise (running wheel) were significantly higher than in animals of the same age which did not exercise (no running wheel). "Investigating the mechanism by which neural stem cell numbers are altered will undoubtedly increase our understanding of how the brain responds to its environment," Dr Blackmore said. "Ultimately, this should allow us to discover how to harness the brain"s regenerative capacity, and to bring about new and effective treatments for conditions caused by trauma, disease, or even normal ageing. "The brain"s ability, even at an advanced age, to respond in a positive manner is very exciting as it extends the time-frame in which manipulation is possible." QBI Director Professor Perry Bartlett FAA said the research represented another significant understanding of the why neural stem cells were so important to brain function. "It is the first experimental data that shows how we can change the propensity of the brain to make new neurons through increasing the number of stem cells - even in the aged animal," Professor Bartlett said. "We can now show that exercise directly causes an increase in the number of stem cells in the brain. "Stem cells develop into neurons and a good supply of neurons is essential for good mental health." The research paper, "Exercise increases neural stem cell number in a GH-dependent manner, augmenting the regenerative response in aged mice", by Dr Daniel Blackmore, Dr Mohammad Golmohammadi, Beatrice Large, Dr Michael Waters and Dr Rodney Rietze appeared in the 14 May online edition of Stem Cells.
