A 'grape' future for Alzheimer's disease research
With National Alzheimer's Awareness Month upon us, attention continues to focus on new approaches to cognitive health in an aging population. view more (2007-11-07)
Scientists develop a new way to target Alzheimer's disease
The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by interfering with the deadly embrace of these proteins. view more (2006-12-05)
Diet of young, pregnant smokers cause for concern
Just under 800 young women, pregnant for the first time, completed detailed seven day food diaries. Around 40 per cent of the women were smokers. Smokers had significantly lower intakes of most vitamins and minerals, although dietary intakes were similar between the smokers and non-smokers. The differences in vitamin C and beta carotenoid intake... view more... (1999-12-13)
New advances may slow tumor growth in pancreatic cancer
Making new strides in their ongoing effort to understand mechanisms behind the relentless growth of cancer cells, researchers at Dartmouth Medical School have found a promising key that may open doors to future treatments in pancreatic and other forms of cancer view more (2005-06-10)
New cancer weapon: nuclear nanocapsules
Rice University chemists have found a way to package some of nature's most powerful radioactive particles inside DNA-sized tubes of pure carbon -- a method they hope to use to target tiny tumors and even lone leukemia cells. view more (2007-08-24)
Scientists identify new strategy for preventing acute and chronic brain disease
Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that reducing levels of the protein tau can prevent seizures and neurological deficits related to Alzheimer's disease. view more (2007-05-04)
Ghrelin: A player in diabetes but not obesity?
Ghrelin, a hormone long considered a key player in obesity, may instead take a major role in maintaining the balance between insulin and glucose and the development of diabetes. view more (2006-05-10)
Kidney disease linked to lower medication use after heart attack
Patients with kidney disease-especially end-stage renal disease (ESRD) requiring dialysis-are less likely to receive recommended medications after a heart attack, reports a study in the September 2008 Clinical Journal of the American Society of Nephrology (CJASN). view more (2008-07-10)
Preclinical study shows chronic stress agitates ovarian cancer; reducing stress slows tumor growth
When mice with ovarian cancer are stressed, their tumors grow and spread more quickly, but that effect can be blocked using a medication commonly prescribed for heart disease. view more (2006-07-24)
Smithsonian scientists show differing patterns of rainforest biodiversity
Rainforests are the world's treasure houses of biodiversity, but all rainforests are not the same. Biodiversity may be more evenly distributed in some forests than in others and, therefore, may require different management and preservation strategies. view more (2007-08-09)
Refuted claims from observational studies often persist despite strong evidence against them
Prominent claims from observational studies of the cardiovascular benefits of vitamin E often continue to be supported in medical literature despite strong contradictory evidence from randomized trials. view more (2007-12-05)
Sleep apnea may not be closely linked to heart failure severity
Obstructive sleep apnea (OSA) and central sleep apnea (CSA) are not markedly decreased in heart failure (HF) patients managed with beta-blockers and spironolactone. view more (2009-05-06)
New study reveals signaling pathways required for expansion of pancreas stem cells
IDDM, which used to be referred to as Type 1 diabetes, results from selective destruction of insulin-producing pancreatic islet beta cells by the body's immune system. view more (2006-05-17)
Deadly infectious entity of prions discovered
The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape of the prion protein's structure. view more (2005-06-10)
Genetic variation may reduce Alzheimer's risk
Adults with a genetic variation enabling them to express higher levels of fetal hemoglobin may have a reduced risk of Alzheimer's disease, researchers say. view more (2007-01-09)
Understanding Heart Disease: Research Explains Link Between Cholesterol and Heart Disease
Cholesterol contributes to atherosclerosis - a condition that greatly increases the risk of heart attack and stroke - by suppressing the activity of a key protein that protects the heart and blood vessels, researchers at the Saint Louis University School of Medicine have found. view more (2007-09-19)
Enzyme action creates protein linked to Alzheimer's disease
Researchers at UT Southwestern Medical Center have defined a key step in the production of beta-amyloid, a short protein that is thought to be responsible for the development of Alzheimer's disease. view more (2005-08-15)
Looking beyond the drug receptor for clues to drug effectiveness
Antipsychotic drugs that are widely used to treat schizophrenia and other problems may not work as scientists have assumed, according to findings from Duke University Medical Center researchers that could lead to changes in how these drugs are developed and prescribed. view more (2008-08-26)
A high fat, low carbohydrate diet improves Alzheimer's disease in mice
Mice with the mouse model of Alzheimer's disease show improvements in their condition when treated with a high-fat, low-carbohydrate diet. view more (2005-10-17)
New strains of symbiotic nitrogen fixing Proteobacteria
Nitrogen is essential for plant growth. Legumes, representing the Earth's largest family of plants, can fix atmospheric nitrogen necessary for their growth thanks to an association with bacteria, the rhizobia. This ability proves to be particularly valuable when soils are poor in nitrogen. The nitrogen fixing symbiosis occurs in nodules,... view more... (2001-06-19)
