Proteins linked with Alzheimer's, other neurodegenerative diseases found to clump in normal aging

In neurodegenerative diseases, clumps of insoluble proteins appear in patients' brains. These aggregates contain proteins that are unique to each disease, such as amyloid beta in Alzheimer's disease, but they are intertwined with small amounts of many other insoluble proteins that are normally present in a soluble form in healthy young individuals. For years, these other proteins were thought to be accidental inclusions in the aggregates, much as a sea turtle might be caught in a net of fish. more  

Study finds similar personality types in male and female domestic violence perpetrators

New research published in the August edition of the American Psychological Association's Journal of Abnormal Psychology, is providing a better picture of the roles played by gender, personality and mental illness in domestic violence. more

Molecular imaging identifies high-risk patients with heart disease

A study published in the August Journal of Nuclear Medicine (JNM) finds that molecular imaging—a non-invasive imaging procedure—can identify high-risk patients with potentially life-threatening cardiovascular conditions and help physicians determine which patients are best suited for implantable cardioverter defibrillator (ICD) therapy. more  

Breast cancer risk varies among different progestins used in hormone replacement therapy, MU researchers finds

Progestins are used in hormone replacement therapies to counteract the negative effects of estrogen on the uterus and reduce the risk of uterine cancer. However, evidence in recent studies and clinical trials has demonstrated that progestins increase the risk of breast cancer. Now, University of Missouri researchers have compared four types of progestins used in hormone replacement therapies and found significantly different outcomes on the progression of breast cancer in an animal model depending on the type of progestins used. more

Distinguishing ‘senior moments’ from Alzheimer’s  

With the help of volunteers aged 18 to 89, UC Irvine researchers have identified for the first time in humans a long-hidden part of the brain called the perforant path. Scientists have struggled for decades to locate the tiny passage, which is believed to deteriorate gradually as part of normal aging and far more quickly due to Alzheimer’s disease. more

Chemical system in brain behaves differently in cocaine addicts, UT Southwestern scientists find  

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug. more

Adequate zinc eases pneumonia in elderly

A high proportion of nursing facility residents were found to have low serum (blood) zinc concentrations during an observational study funded by the Agricultural Research Service (ARS) and the National Institute of Aging. The scientists found that those with normal blood zinc concentrations were about 50 percent less likely to develop pneumonia than those with low concentrations. more
