Stress response reduces memory during tests in older adults

Your mother had a doctor's appointment for a memory test. The results are conclusive: she presents with the first signs of Alzheimer type dementia. Now, to get to her appointment, your mother, who is no longer used to driving in town, took her car, looked for a parking space for 15 minutes, got lost in a labyrinth of one-way streets, had never used those new electronic parking meters before and is convinced that the "machine" stole her credit card number.

Data supports links between AD and diabetes: New study

Alzheimer's disease is the sixth leading cause of death in the United States and the only cause of death among the top 10 in America without a way to prevent, cure or even slow its progression, according to the Alzheimer's Association. Today, 5.4 million Americans are living with the disease, and another American develops it every 69 seconds.

Researchers use game theory to understand dynamics of cancer tumor evolution under stress

In search of a different perspective on the physics of cancer, Princeton University and University of California, San Francisco researchers teamed up to use game theory to look for simplicity within the complexity of the dynamics of cooperator and cheater cells under metabolic stress conditions and high spatial heterogeneity. In the context of cancer, cooperator cells obey the general rules of communal survival, while cheater cells do not.

Defects in schizophrenia-risk genes and environmental stress lead to abnormal brain development

Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect one's risks for schizophrenia and abnormal brain development in general.

UAB cardiac rehab program reduces mortality among people with heart attack

After two heart attacks and 10 stents, Rick Vinson had a decision to make — do nothing and likely die from heart disease like his father or take a chance at having a long life. Vinson chose the latter. After receiving his last stent in October 2010, he entered a cardiac rehab program at the University of Alabama at Birmingham. Since then he has dropped 20 pounds, his cholesterol has dropped to 141 from 315 and his triglycerides are down to 149 from 465.

CCTA can safely and rapidly identify candidates for discharge from EDs

Coronary CT angiography (CCTA) -- a non-invasive way to look inside arteries that supply blood to the heart -- can quickly and reliably determine which patients complaining of chest pain at an emergency department can safely be sent home, according to research presented today at the American College of Cardiology's 61st Annual Scientific Session.

DBS allows surgeons to control tremors with brain 'pacemaker'

For nearly 30 years, Tom Rogers' left hand would shake when he tried to use it, making even simple tasks such as drinking a glass of water, writing a check, or making a sandwich challenging. The tremor eventually became so disruptive that he lost use of his dominant hand. Rogers sought care and learned that his tremor was a symptom of Parkinson's disease, yet felt he was suffering from something different.

ACS symposium focuses on biomimetics

Combining the secrets that enable water striders to walk on water and give wood its lightness and great strength has yielded an amazing new material so buoyant that, in everyday terms, a boat made from 1 pound of the substance could carry five kitchen refrigerators, about 1,000 pounds.

Pregnancy raises risk of heart attacks

According to a new study pregnancy and related hormonal changes that continue 12 weeks after giving birth increase a woman's risk of heart attack. Although the likelihood of having a heart attack during pregnancy is very low - just 1 in every 16,000 deliveries - it is still 3 to 4 times higher than non-pregnant women of the same age.
