Flatworms yield insights (December 11, 2005)
If you take a planarian flatworm and chop it in half, something extraordinary happens: One section grows a new head, the other a new tail, and soon you have two new flatworms. Chop it into quarters, or eighths, and you'll notice the same thing. For centuries researchers have puzzled over this biological phenomenon, but only recently have they understood that these creatures are a goldmine for exploring how stem cells regenerate damaged tissue. Now, researchers at Whitehead Institute for Biomedical Research and University of Utah School of Medicine have begun to understand the biological processes of how the planarian flatworm achieves in itself what researchers hope to one day accomplish in the clinic: complete regeneration of damaged tissue.

Hole in Heart Does Not Make Stroke Always (December 11, 2005)
Mayo Clinic scientists have found that -- contrary to current thinking by some in the medical community -- a patent foramen ovale (PFO), a small hole between the two upper chambers of the heart, does not predestine an individual to a stroke later in life. Findings will appear online on Friday, Dec. 9 in the Journal of the American College of Cardiology.

Threat of Avian Influenza Pandemic Grows (December 11, 2005)
An editorial in the recent issue of Mayo Clinic Proceedings paints a picture of a world population very susceptible to an avian flu pandemic, but also offers suggestions to physicians that could help answer questions presented by patients who may be feeling anxious about the "bird flu."

Protein Guides HIV Integration into Human Genome (December 11, 2005)
A Mayo Clinic research collaboration has discovered that a human protein - LEDGF - plays a guiding role in where HIV inserts itself in the human genome. The findings appear in the current edition of Nature Medicine (Opens in a new window). Collaborating scientists are from the University of Pennsylvania and the Salk Institute.

Holiday Air Travel with Infants and Toddlers (December 11, 2005)

Month Following Heart Attack (December 11, 2005)
A Mayo Clinic research team discovered that heart attack patients have a 44-fold increased risk of stroke in the 30 days following the heart attack, compared with the general population, according to findings published in the current Annals of Internal Medicine. About 22.6 strokes occurred within the first 30 days of the heart attack for every 1,000 patients followed.

Redefining How Heart Functions (December 11, 2005)
Contrary to the widely accepted explanation that the human heart is simply a pump, Mayo Clinic scientists have uncovered novel findings on how cardiac muscle operates. The findings will appear in the Jan. 3, 2005, issue of the Journal of the American College of Cardiology. "Redefining how the heart functions is one of the first steps that could lead to revolutionary approaches to treating patients who have heart failure - 5 million and growing in the U.S. - or better yet, preventing the heart failure from developing," says Bijoy Khandheria, M.D., chair of the Division of Cardiology at Mayo Clinic in Arizona and one of the co-authors of the study.

Stroke Risk Significant in Month Following Heart Attack (December 11, 2005)
A Mayo Clinic research team discovered that heart attack patients have a 44-fold increased risk of stroke in the 30 days following the heart attack, compared with the general population, according to findings published in the current Annals of Internal Medicine. About 22.6 strokes occurred within the first 30 days of the heart attack for every 1,000 patients followed.

Solutions for Quality of Life Assessments (December 11, 2005)
Mayo Clinic Cancer Center scientists recently published the first series of chapters in a two-part monograph discussing quality of life (QOL) assessment -- best practices, promising techniques and revolutionary applications. The monograph was published in the November-recent issue of Current Problems in Cancer, with the second half to follow in early 2006.

Smoking After Cancer Diagnosis (December 11, 2005)
A pair of articles from The University of Texas M. D. Anderson Cancer Center makes the case that patients would receive better care if physicians and scientists would address the issue of tobacco use after a cancer diagnosis and monitor tobacco use during clinical trials that test new agents.
