Researchers at the University of Michigan have published the findings of their work on Alzheimer's care in a recent edition of Journal of the American Chemical Society. Alzheimer's disease (AD) is characterized by memory loss and other cognitive difficulties associated with clumps of peptides called amyloid betas that form the plaque that kills braincells.  In order to learn how to prevent brain damage, scientists must learn how these clumps form, and the researchers at U of M have developed new molecular tools that could help make the discovery.Though the origins of the clumps are still unknown, scientists think copper ions are involved in their formation, as this metal is believed to cause cell damage in certain contexts. Researchers sometimes study the role of copper in the clumping process by combining metal ions with a certain kind of molecule called a chelator. In the past, scientists have found that by then removing the metals from the molecule, they can make the chelator hamper the clumping. Though scientists frequently conduct research on AD, the Mayo Clinic says the disease has no cure. Nearly 50 percent of Americans over the age of 85 have AD. © Copyright |

Overactive immune response complicates eldercare
Thursday, November 19, 2009
Research conducted by experts at the Yale School of Medicine suggests some seniors have an overactive immune response, which can have an negative impact on retirement living.
The researchers discovered that exaggerated responses by the immune systems of some elderly people could be responsible for certain health problems like viral infections.

New information regarding eldercare for seniors with coronary artery disease
Thursday, November 19, 2009
Research recently conducted in Maryland involving over 100 elderly men and women could have an impact on the eldercare that seniors with coronary artery disease receive.
In Baltimore, 145 men and women over the age of 65 with atherosclerosis were tested by experts from Johns Hopkins to see if dual niacin-statin therapy was more effective than traditional cholesterol-lowering therapy. Some doctors believe that niacin, often referred to as vitamin B3, can add benefit in correcting arterial narrowing when combined with statins, which are the drugs used in conventional cholesterol treatment.
"Our recommendation to physicians is that current national treatment guidelines, which recommend mainly statin therapy tailored to the severity of atherosclerosis for preventing arteries from reclogging and narrowing, appear to be sufficient and accurate for physicians and patients to follow," said Dr Joao Lima of Johns Hopkins.

Heart research could affect eldercare
Tuesday, November 17, 2009
Research presented at the Amercian Heart Association's Scientific Sessions 2009 event could help prevent both younger and older persons from suffering brain damage during cardiac arrest.
When a person experiences a sudden loss in heart function, it might be possible to protect them from brain damage by quickly cooling their body.
"We now have a method that is safe and can be started within minutes of cardiac arrest to minimize damage during this very critical period," said Dr Maaret Castren, the lead author of the study.
The researchers examined 200 adult patients who went into cardiac arrest.
