- Stanford scientists make major breakthrough in regenerative medicine
04-24-2007 · EurekAlert!
Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine -- a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.

- Cross-species transplant in rhesus macaques is step toward diabetes cure for humans
10-18-2007 · EurekAlert!
With an eye on curing diabetes, scientists at Washington University School of Medicine in St. Louis have successfully transplanted embryonic pig pancreatic cells destined to produce insulin into diabetic macaque monkeys -- all without the need for risky immune suppression drugs that prevent rejection.

- Paving the way toward a vaccine against Alzheimer's disease
06-21-2007 · EurekAlert!
Scientists have provided new details about how proteins used to destroy bacteria and viruses may help treat Alzheimer's disease. Gunnar K. Gouras, associate professor of neurology and neuroscience at Weill Medical College of Cornell University, New York, and colleagues provide new insights into how these proteins, called antibodies, reduce the main hallmarks of Alzheimer's disease and raise hopes for a vaccine against the disease.

- Alzheimer's prevention role discovered for prions
07-03-2007 · EurekAlert!
A role for prion proteins, the much debated agents of mad cow disease and vCJD, has been identified. It appears that the normal prions produced by the body help to prevent the plaques that build up in the brain to cause Alzheimer’s disease. The possible function for the mysterious proteins was discovered by a team of scientists led by Medical Research Council funded scientist Professor Nigel Hooper of the University of Leeds.

- Adult pig stem cells show promise in repairing animals' heart attack damage
11-13-2006 · EurekAlert!
Johns Hopkins scientists have successfully grown large numbers of stem cells taken from adult pigs' healthy heart tissue and used the cells to repair some of the tissue damage done to those organs by lab-induced heart attacks. Pigs' hearts closely resemble those in humans, making them a useful model in such research.

08-20-2007 · Brookhaven National Laboratory
In an effort to develop alternative energy sources such as fuel cells and solar fuel from "artificial" photosynthesis, scientists at the U.S. Department of Energy's Brookhaven National Laboratory are taking a detailed look at electrons - the particles that set almost all chemical processes in motion.

- Biorefining of corn brings gelatin production into the 21st century
08-22-2007 · EurekAlert!
Scientists are reporting an advance toward turning corn plants into natural factories for producing gelatin to replace animal-sourced gelatin widely used by the pharmaceutical industry for manufacturing capsules and tablets. The advance may lead to a safe, inexpensive source of this protein for manufacturers who now rely on material obtained as a byproduct of meat production. The study will be reported in August at the American Chemical Society national meeting in Boston.

- Key Function Of Nervous System Enzyme Found; Impact On Drug Development Against Alzheimer's
09-29-2006 · ScienceDaily
Ever since scientists first elucidated the molecular mechanisms underlying the pathology and loss of nerve cells in Alzheimer's disease, drug companies have been working to develop drugs which will inhibit the outbreak of this severe form of dementia. Now researchers in Munich and Berlin (Germany) have discovered that an enyzme which has a central causal role in Alzheimer's disease happens also to have a key function in the normal development of the nervous system. This enzyme, beta-secretase or BACE1, ensures that nerve fibers (axons) are adequately isolated with sheaths of myelin, enabling rapid conduction of electrical impulses, as well as preventing short-circuits, akin to plastic insulation on electrical wires.
