Bone Marrow Alternative: Stem Cells From Umbilical Cord May Be Used To Treat Hepatic Diseases (July 5, 2008) -- Researchers from the Universities of Granada and León have shown that mononuclear blood cells from human umbilical cord can be an effective alternative to bone marrow. This work, to be published in the journal Cell Transplantation, could potentially mean a great advance in regenerative hepatic medicine. ... > full story
Women Over 90 More Likely To Have Dementia Than Men (July 5, 2008) -- Women over 90 are significantly more likely to have dementia than men of the same age, according UC Irvine researchers involved with the 90+ Study, one of the nation's largest studies of dementia and other health factors in the fastest-growing age demographic. ... > full story
Scientists Set Out To Measure How We Perceive Naturalness (July 5, 2008) -- Scientists at the National Physical Laboratory are working towards producing the world's first model that will predict how we perceive naturalness. The results could help make synthetic products so good that they are interpreted by our senses as being fully equivalent to the "real thing," but with the benefits of reduced environmental impact and increased durability. ... > full story
Seizures In Newborns Can Be Detected With Small, Portable Brain Activity Monitors (July 5, 2008) -- Compact, bedside brain-activity monitors detected most seizures in at-risk infants. That means the compact units could assist clinicians in monitoring for electrical seizures until confirmation with conventional EEG, the researchers assert in an article in Pediatrics. ... > full story
Coronary Arterial Calcium Scans Help Detect Overall Death Risk In The Elderly (July 5, 2008) -- Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study in the Journal of the American College of Cardiology. ... > full story
Weight Watchers Vs. Fitness Centers (July 5, 2008) -- The nationally known commercial weight loss program, Weight Watchers, was compared to gym membership programs to find out which method wins in the game of good health.

Breast Cancer: How Tumor Cells Break Free And Form Metastases (July 5, 2008) -- When tumor cells acquire the capacity to move around and invade other tissues, there is a risk of metastases and cancer treatment becomes more difficult. Scientists have just discovered how breast cancer cells break the bonds that tether them to the tumor. ... > full story
How Cold Sore Virus Hides During Inactive Phase (July 5, 2008) -- Now that scientists have figured out how the virus that causes cold sores hides out, they may have a way to wake it up and kill it. Cold sores, painful, unsightly blemishes around the mouth, have so far evaded a cure or even prevention. ... > full story
Healthy Or Diseased? Analysis Of Body's Metabolism Sheds New Light On The Question (July 5, 2008) -- Scientists have shown that biological indicators for diseases caused or influenced by environmental factors can be detected by the systemic analysis of the body's metabolism (metabolomics). The procedure presented here is also suitable for pre-clinical drug testing and allows for the early detection of possible side effects of a new medication. ... > full story
Researchers Coat Titanium With Polymer To Improve Integration Of Joint Replacements (July 5, 2008) -- New research shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone. ... > full story
Depression Ups Risk Of Complications Following Heart Attack, Study Suggests (July 5, 2008) -- People who suffer from severe depression following a heart attack might be more likely to experience cardiac complications while hospitalized, according to a new study. "There is good evidence that if a person has depression after a heart attack, they are more likely to die from cardiac causes in the following months and years," said the lead author and assistant professor at Harvard Medical School. "No one had yet studied whether depression impacts cardiac outcomes immediately after a heart attack -- the time we see the most complications." ... > full story
'Mind's Eye' Influences Visual Perception (July 4, 2008) -- Letting your imagination run away with you may actually influence how you see the world. New research has found that mental imagery -- what we see with the "mind's eye" -- directly impacts our visual perception. ... > full story
