- Immune responses spread from one protein to another in type 1 diabetes
12-01-2006 · EurekAlert!
Type 1 diabetes (T1D) occurs when the immune system inappropriately attacks cells in the pancreas. Although many of the proteins attacked during T1D have been identified, it has not been determined whether immune responses to the individual proteins develop independently or whether a response to one protein then spreads to others. Now, a new study shows that in mice the immune system first attacks a single protein and then expands its attack to other proteins.

- Researchers use new method to probe recollections in memory-impaired patients
02-04-2008 · EurekAlert!
Neuroscientists continue to debate whether or not long-term memory always depends on a region of the brain called the medial temporal lobe, which contains the brain's memory-processing center, the hippocampus. A new study of brain-damaged patients by researchers at the University of California-San Diego School of Medicine readdresses the issue using a new method to elicit more detailed long-term memories.

- First human trial tests stem-cell-based treatment for heart attacks
03-25-2007 · EurekAlert!
Previous research on the efficacy of stem cell therapy for heart repair has shown possible benefit from mesenchymal stem cells (MSCs) -- cells found in bone marrow that create connective tissue, bone and cartilage. A study presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit reveals the results of the first human trial using MSCs for the treatment of myocardial infarction (MI, or heart attack).

- UMass Medical School study finds patients diagnosed with coronary heart disease continue poor diets
01-30-2008 · EurekAlert!
More than 13 million Americans have survived a heart attack or have been diagnosed with coronary heart disease, the number one cause of death in the United States. In addition to medications, lifestyle changes, such as a healthy diet and exercise, are known to reduce the risk for subsequent cardiac events. Despite this evidence, a high proportion of heart attack survivors do not follow their doctor's advice to adhere to a healthy diet.

- Dementia on the rise in aging populations
10-30-2006 · EurekAlert!
Life expectancy continues to rise in most countries around the world, and in industrialized nations it is not uncommon for people to live well into their 90s. One consequence is that dementia will become much more common as a new study published in PLoS Medicine suggests.

04-12-2007 · EurekAlert!
Psychiatric nurses face real and highly understandable fears, but they take firmer action when patients attack staff than when they attack other patients. The study of 254 aggressive incidents in London psychiatric wards appears in the latest Journal of Advanced Nursing.

- Study analyzes heart attack mortality risk associated with Hodgkin disease treatments
02-06-2007 · EurekAlert!
Doctors have long known that patients treated for Hodgkin disease are at an increased risk for heart attacks. In the February 7 issue of the Journal of the National Cancer Institute, researchers quantify the risk of fatal heart attacks associated with different types of treatment, and they find that the increased risk persists for at least 25 years after Hodgkin disease treatment.

- Living arrangements, health and well-being: A European perspective
11-15-2007 · EurekAlert!
Ageing populations are an increasing issue for the Western world. The proportion of people over aged 60 is growing plus there has been a rise in older men and women living alone and a decline in those living with children or relatives. A new study, funded by the Economic and Social Research Council, analysed the impact of living alone, with a spouse or with others on the health and happiness of older people and how it varies within Europe and in England and Wales.

- Neural stem cell study reveals mechanism that may play role in cancer
09-04-2007 · EurekAlert!
In the dynamic world of the developing brain, neural stem cells give rise to neurons deep within the brain’s fluid-filled ventricles. These newborn neurons then migrate along the stem cell fibers up to the neocortex, the seat of higher cognitive functions. Now, scientists have discovered a key mechanism of this migration -- one that may also play an important role in other developmental processes and diseases, including cancer.
