NIH grants $2.5M for the study of physical forces on cell function

The National Institutes of Health today announced an award of $2.5 million to a team led by Boston University biomedical engineer Bela Suki that will study the role of physical forces on cell function, with the goal of understanding the possible roles of these forces in diseases like atherosclerosis, neuro-degenerative diseases, metabolic disorders, aging and cancer.

Research study links high-fructose diet to increased blood pressure in men

A high-fructose diet raises blood pressure in men, while a drug used to treat gout seems to protect against the blood pressure increase, according to research reported at the American Heart Association's 63rd High Blood Pressure Research Conference.

Lab-on-a-chip performs 1,000 chemical reactions at once

Flasks, beakers, and hot plates may soon be a thing of the past in medicinal chemistry labs. Instead of handling a few experiments on a benchtop, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results literally shrinking the lab down to the size of a thumbnail.

Drugs blocking the effects of ACh may prevent cancer

By seeing what substances and molecules affect the development of our diseases, we can develop drugs that prevent or cure diseases. In her dissertation at Kalmar University in Sweden, Ann Novotny has found that the signal molecule acetylcholine (ACh) is important for the progress of cancer of the large intestine and colon, knowledge that is important to factor in when developing drugs that block the effects of Ach on tumor cells.

New method to identify active tuberculosis in patients

Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers. Active tuberculosis (TB) is the seventh-leading cause of death worldwide, and while the diagnosis of active TB can be rapidly established when the bacteria can be identified on sputum microscopy, in about half of all cases, the TB bacterium cannot be detected, making another diagnostic option critical in efforts to control the spread of TB.

Preventing nerve cell death in diabetics

Dennis Paul, PhD, Associate Professor of Pharmacology, and Harry Gould, MD, PhD, the Tom Benson Professor of Neurology at LSU Health Sciences Center New Orleans, have been awarded one of two scientific research grants made in 2009 by The Neuropathy Association. The $80,000 grant will fund research to learn how to prevent nerve cell death in people with uncontrolled or untreated diabetes resulting in neuropathy.

Researching the causes of Alzheimer's disease

The standard explanation for what causes Alzheimer's is known as the amyloid hypothesis, which posits that the disease results from of an accumulation of the peptide amyloid beta, the toxic protein fragments that deposit in the brain and become the sticky plaques that have defined Alzheimer's for more than 100 years.

Declining performance of muscles linked to harmful byproducts of air we breathe

If you think the air outside is polluted, a new research report in the September 2009 issue of the journal Genetics (http://www.genetics.org) might make you to think twice about the air inside our bodies too. That's because researchers show how about 3 percent of the air we breathe gets converted into harmful superoxides, which ultimately harm our muscles.

Antigen to block infection by genetically-diverse strains of HIV

Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vaccines by virtue of its chemically-activated property that enables close sharing of electrons and produces strong covalent bonding.

Industrial lipases launched by EUCODIS Bioscience

EUCODIS Bioscience, a company developing, customizing, manufacturing, and marketing enzymes for the chemical industry, announced today that it has launched the first enzymes of its lipase portfolio. EUCODIS Bioscience currently offers 12 lipases that have been selected to cover a broad range of potential industrial applications.

Blood vessels around the brain now converted into production/delivery systems

The blood brain barrier is generally considered an obstacle to delivering therapies from the bloodstream to the brain. However, University of Iowa researchers have discovered a way to turn the blood vessels surrounding brain cells into a production and delivery system for getting therapeutic molecules directly into brain cells.

Coenzyme Q10 to slow down the effects of Parkinson's disease?

Rush University Medical Center is participating in a large-scale, multi-center clinical trial in the U.S. and Canada to determine whether a vitamin-like substance, in high doses, can slow the progression of Parkinson's disease, a neurodegenerative disorder that affects about one million people in the United States.

Interim data from Micromet's T-cell engaging BiTE antibody study for treating solid tumors

Micromet, Inc. (Nasdaq: MITI), a biopharmaceutical company developing novel, proprietary antibodies for the treatment of cancer, inflammation and autoimmune diseases, today presented first interim data from a phase 1 dose-escalation clinical study for BiTE antibody MT110, the first T-cell engaging antibody for the treatment of solid tumors.

Signaling molecules have different effects on key inhibitory protein

Researchers have identified a mechanism that may keep a well known signaling molecule from eroding bone and inflaming joints, according to an early study published online today in the Journal of Clinical Investigation.

Novel cleavage sites for enzyme caspase-3 identified

Investigators at Burnham Institute for Medical Research (Burnham) have identified novel cleavage sites for the enzyme caspase-3 (an enzyme that proteolytically cleaves target proteins). Using an advanced proteomic technique called N-terminomics, Guy Salvesen, Ph.D., professor and director of the Apoptosis and Cell Death Research program of Burnham's NCI-designated Cancer Center, and colleagues determined the cleavage sites on target proteins and found, contrary to previous understanding, that caspase-3 targets α-helices as well as unstructured loops.
