Molecule P-glycoprotein (Pgp), may help reduce risk of Alzheimer's

A molecule that has long been an obstacle to cancer chemotherapy and drug treatments for brain disorders may soon become an ally in the fight against Alzheimer's disease, according to researchers at Washington University School of Medicine in St. Louis and the University of Rochester.

Alzheimer disease and the blood brain barrier

Increased production of the amyloid-beta (Abeta) peptide can lead to Abeta aggregation and buildup in the brain and rare familial forms of early onset Alzheimer disease (AD).

Aβ and Fyn cooperate to cause Alzheimer-like changes in the brain

Reporting in two companion papers in the October 19 issue of the Journal of Neuroscience, investigators from the Gladstone Institute of Neurological Disease show in genetically engineered mouse models of the disease that the accumulation of Alzheimer-related neurotoxic amyloid-beta (Aâ) peptides can deplete key proteins in a specific memory center of the brain.

dnaJP1 - novel drug for the treatment of rheumatoid arthritis

Researchers at the University of California, San Diego (UCSD) School of Medicine have announced successful completion of Phase II clinical trials of a novel drug for the treatment of rheumatoid arthritis (RA), one that works without suppressing the patient's immune system.

New light shed on the causes of drug addiction

A methamphetamine epidemic rages across the United States with addicts blinded by uncontrollable desires for a drug that eventually thrusts them into a dire and catastrophic existence. Doctors don't have any effective treatments for these addicts, or for any other drug addicts; drug addiction is a disease that remains a medical mystery.

Researchers set out to determine the effectiveness of endomorphin 1, with a painkilling capacity equal to or greater than morphine

Nearly one third of the world's adult population suffers with the pain of arthritis. While NSAIDs and COX-2 inhibitors offer the promise of relief, these drugs also bring the risk of adverse effects, from stomach ulcers to heart attack.

Potential beneficial effect of copper orotate

As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt), which is given together with a standard cholinesterase inhibitor.

Salivary antimicrobial peptide expression and dental caries experience in children

A study comparing antimicrobial peptides, or AMPs, a group of small proteins that occur naturally in human saliva and act like antibiotics against oral bacteria, could lead to new ways to screen children for risk of tooth decay and protect them against this common, chronic problem.

Possible therapy that could control blood pressure

A newly developed virus that introduces a blood pressure-lowering gene into cells and enables that gene to maintain blood pressure at healthy levels for four months promises to take gene therapy for the disorder a step closer to reality, said researchers at Baylor College of Medicine in a report released online in the Proceedings of the National Academy of Sciences.

Cancer vaccine based on the bacterium Listeria monocytogenes, can cure mice with breast tumors

A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. Cancer vaccines, which are more properly described as immunotherapy, work by boosting an immune response against tumor-associated antigens.

SARS can infiltrate brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problems, according to an article in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Discovery that protein CD38 interrupts an interaction between the AIDS virus and its point of entry into cells

Cornell University researchers have discovered the 3-D crystal structure of a protein, human CD38, which may lead to important discoveries about how cells release calcium - a mineral used in almost every cellular process.

Key cellular switch that controls glucose production in liver cells

In many patients with type 2 diabetes, the liver acts like a sugar factory on overtime, churning out glucose throughout the day, even when blood sugar levels are high. Scientists at the Salk Institute for Biological Studies discovered a key cellular switch that controls glucose production in liver cells.
