Enzyme family plays role in Alzheimer's

The route to a treatment for Alzheimer's disease may have become more straightforward with the discovery that a key enzyme known to have a major role in this disease is in fact part of a family of enzymes. Only some family members play a role in the progression of this brain-wasting illness, new research at the University of Toronto has found.

Chemotherapy for brain tumors is boosted after vaccine targets resistance-related TRP-2 antigen

In the August issue of the journal Oncogene, researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute describe a molecular mechanism that appears to make malignant brain tumors more vulnerable to chemotherapy after they have been treated with the dendritic cell vaccine.

Venom of marine cone snails may provide an improved treatment for neuropathic pain associated with diabetes

A cone snail toxin discovered by Melbourne researchers has proven to have great potential for easing pain and could provide an improved treatment for neuropathic pain associated with diabetes.

Researchers discover how hepatic-C virus evades immune system in acute and chronic infections

Researchers at Johns Hopkins have uncovered how a majority of the genetic changes in the hepatic-C virus, the most common cause of liver disease, allow it to evade the body's immune system during infection.

Designed drug for combined hormone and chemotherapy treatment

The search for new drugs to fight cancer remains at the top of the to do list for pharmaceutical researchers. A recent variation is polymer chemotherapy agents, drugs that have been attached to a "backbone" of long chain molecules.

Discovery of molecular mechanism that seems to play an important role in Alzheimer's disease

An international team of chemists and molecular biologists has discovered a fundamental molecular mechanism that seems to play an important role in Alzheimer's disease, Parkinson's disease, mad cow disease and two-dozen other degenerative and fatal diseases.

Simple blood test can quickly identify type of congestive heart failure

A simple blood test can quickly identify what type of congestive heart failure (CHF) a patient has, improving diagnostic accuracy; eliminating the need for extensive diagnostic tests, such as heart muscle biopsy or exploratory surgery; and enabling the patient to be treated sooner, according to a study published in the June 7 Journal of the American College of Cardiology.

Combining morphine with small doses of methadone could increase the effectiveness of morphine for the treatment of chronic pain

Although morphine is well known as a highly effective analgesic, its clinical utility is severely limited by the development of drug tolerance, the requirement for increasing doses to maintain analgesic effect, and the development of physical dependence.

Association between inflammation from knee injuries and a progressive loss of joint lubrication

Researchers have found an association between inflammation from knee injuries and a progressive loss of joint lubrication, which may predispose people to arthritis. They have also found a way to quantify how much lubrication is lost following injury.

New Calcitonin drug delivery research holds promise for osteoporosis sufferers

Calcitonin, a hormone that lowers calcium levels in the blood and prevents bone loss, has only been available in an injectable and nasally-administered format to date.

New understanding of DNA repair processes may pave way to cancer treatments

A Burnham Institute study has found that a protein known for its role in gene regulation has another important function, that of initiating DNA repair. The study, published in the May 27th edition of Molecular Cell, points to new targets for treatment of cancer.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked

Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells known as lymphocytes would recognize the trespassers and attack them.

Engineers have found a way to modify a plastic to anchor molecules that promote nerve regeneration, blood vessel growth or other biological processes

In the study led by Dr. Christine Schmidt, the researchers identified a piece of protein from among a billion candidates that could perform the unusual feat of attaching to polypyrrole, a synthetic polymer (plastic) that conducts electricity and has shown promise in biomedical applications.

Valium puts humans and amoeba to sleep

Biologists at University of California, San Diego (UCSD) have discovered that the popular sedative Valium has similar effects on the social amoeba Dictyostelium discoideum as it does in humans. Their surprising finding that Valium, as well as a "natural Valium" molecule found in human brains, causes the social amoeba to enter a dormant or "sleep" phase, may provide new insights into how cells in higher organisms, including humans, communicate with each other.

Unsuspected protein CD147, regulates the production of plaque-forming peptides that are the defining feature of Alzheimer's

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory have discovered an unsuspected subunit of the protein complex gamma-secretase, which plays a central role in Alzheimer's disease.

Two-sided coating could breathe life into medical implants

By mimicking an adhesive protein secreted by mussels and a polymer that repels cells and proteins, researchers at Northwestern University have designed a versatile new two-sided coating that could breathe life into medical implants.
