UCSD researchers maintain stem cells without contaminated animal feeder layers
The growth and maintenance of human embryonic stem cells in the absence of contaminated animal products has been demonstrated by University of California, San Diego (UCSD) School of Medicine researchers in the Whittier Institute, La Jolla, California. Published in the April 2005 issue of the journal Stem Cells, the study shows that laboratory culture media enriched by a human protein calle...Gray wolves maintain the food chain in winter
Climate change has already had dramatic effects on individual species, with disruptions in range, reproductive success, and seasonal phenomena like migration. But, in a new study from the open-access online journal PLoS Biology (www.plosbiology.org), Christopher Wilmers and Wayne Getz show that the impact of climate change on many different species in Yellowstone Park can be buffered by a top pre...Leptin-signaling Protein Maintains Normal Body Weight And Energy Balance In Mice
32% increase of African fish supply needed by 2020 just to maintain consumption levels Calling fisheries critical for nourishing the poor and for helping Africa cope with the health, economic and social devastation of problems like HIV and AIDS, the New Partnership for Africa's Development (NEPAD), the WorldFish Center and partners are making an urgent appeal to boost the continent's fish...Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal
A team of scientists at the Weizmann Institute of Science, led by Prof. Michal Schwartz of the Neurobiology Department, has come up with new findings that may have implications in delaying and slowing down cognitive deterioration in old age. The basis for these developments is Schwartz's team's observations, published today in the February issue of Nature Neuroscience, that immune cells contribut...Neuroscientists discover new cell type that may help brain maintain memories of smells
Neuroscientists at Case Western Reserve University School of Medicine have discovered a new cell type in the part of the brain that processes our sense of smell. This new cell type, the Blanes cell, is a member of a group of previously unstudied brain cells described by the Spanish neuroanatomist Blanes (pronounced blon ?es) in the late 1800s. Blanes cells have unusual properties which may help...Maintaining High Sensitivity when Working with Small-Volume Samples

MADISON The white board in the middle of the emergency room that lists each patient and their condition is a familiar scene in many hospitals. But is it a violation of patient privacy? Balancing the best interest of the patient but still providing information to the many care givers that require it was the top...How Wisconsin Can Maintain Its Lead in Stem Cell Research
MADISON South Korea is a nation deeply imbued with Confucian values, such as the belief that human bodies are inherited from ancestors and should never be tampered with. So there was understandable culture clash in Seoul last week when South Korean researchers announced they had become the first to clone a mature, human embryo and then collect from it master stem cells in a process that may som...Telomerase Vital In Maintaining Ability of Stem Cell to Multiply
Carol Greider, Ph.D., director and professor of molecular biology and genetics in the Johns Hopkins Institute of Basic Biomedical Sciences and colleagues have found that the length of telomeres is important// in ensuring that stem cells are able to divide indefinitely. Telomeres are the ends of the chromosomes that protect genetic information while the chromosome is undergoing division....Weizmann Institute of Science says Immune Cells Could Help Maintain Brain Function
New research from the Weizmann Institute of Science throws light on cells that could prevent deterioration of cognition in old age. These findings appear in the February issue of Nature Neuroscience. Professor Michal Schwartz of the Neurobiology Department at Weizmann led the study, //which might have important implication in delaying the onset of cognitive deterioration in the elderly....Blood Pressure Drugs maintain muscle strength
Drugs used to reduce blood pressure could help to keep elderly people fitter for longer by slowing the physical decline that accompanies age.// ACE inhibitors prevent high blood pressure by blocking an enzyme that causes blood vessels to constrict. The drugs also help to preserve muscle strength in patients suffering from congestive heart failure (CHF). Researchers said the drug...Vitamin C maintains healthy lungs
According to a recent study, the researchers confirmed that people who consume high levels of vitamin C and magnesium tend to have healthier lungs. And for the first time, the research showed that people with high levels of vitamin C intake experience less decline in lung function over time.// Just like an apple a day keeps the doctor away, an orange a day may help keep lung disease away,...Maintaining warmth during cold
Avoid hypothermia by following a few tips on dressing well given by an emergency doctor. There is no need to feel you've got to stay indoors when the weather is cold. A brisk walk and exposure to sunlight will do you a lot of good.// But it's important to dress properly if you want to avoid the ill-effects of cold weather. Just putting on a woolly scarf and a pair of gloves isn't necessar...Study Suggests Invega Helps Patients With Schizophrenia Maintain Symptom Control
52-Week Trial Maintained Improvement in Personal and SocialPerformance COLORADO SPRINGS, Colo., March 30, 2007 /PRNewswire/ --Longer-term treatment with INVEGA(TM) (paliperidone)Extended-Release Tablets, a new once daily oral medication forschizophrenia, helped many patients effectively control theirsymptoms and maintain their improvements in personal and socialfunctioning....
