New research helps explain why treated genital herpes sores boost risk of HIV infection

New research helps explain why infection with herpes simplex virus-2 (HSV-2), which causes genital herpes, increases the risk for HIV infection even after successful treatment heals the genital skin sores and breaks that often result from HSV-2.

New blood tests may detect pancreatic cancer more effectively

A new diagnostic tool developed by Van Andel Research Institute (VARI) scientists has shown promising results when used with patients of pancreatic cancer, one of the deadliest forms of cancer due to the difficulty of diagnosing it in its early stages. The method, which studies carbohydrate structures in the bloodstream, could lead to the development of blood tests that can detect cancer more effectively.

New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, 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.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Selective method kills metastatic melanoma cells

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma - a cancer that is highly resistant to current treatment strategies.

FDA approves Avastin plus interferon-alfa for people with metastatic renal cell carcinoma

Genentech, Inc. today announced that the U.S. Food and Drug Administration (FDA) approved Avastin (bevacizumab) plus interferon-alfa for people with metastatic renal cell carcinoma, the most common type of kidney cancer. According to the American Cancer Society, kidney cancer is the eighth most commonly diagnosed cancer in the United States. In 2009, approximately 13,000 Americans will die from the disease.

Gene therapy for retinitis pigmentosa

An international team of scientists and clinicians from the United States and Saudi Arabia are working to develop gene therapy for treating a rare, hereditary retinal disease.

Common food additive lecithin may help control blood lipids and reduce disease risk

Scientists at Washington University School of Medicine in St. Louis have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes, hypertension or cardiovascular disease using treatments delivered in food rather than medication.

Heat shock proteins provide protection against cataracts

The human eye lens consists of a highly concentrated mix of several proteins. Protective proteins prevent these proteins from aggregating and clumping. If this protective function fails, the lens blurs and the patient develops cataracts. Two research groups at the Department of Chemistry of the Technische Universitaet Muenchen (TUM) have succeeded in explaining the molecular architecture of this kind of protective protein.

Discovery of genetic link to age-related cataracts

Bing-Cheng Wang, Ph.D., Case Western Reserve University School of Medicine professor of pharmacology and senior staff scientist at MetroHealth Medical Center, and Sudha K. Iyengar, Ph.D. professor of genetic and molecular epidemiology at Case Western Reserve University School of Medicine, have discovered the first gene associated with the formation of age-related cataracts, a leading causes of blindness.

Dynamic, 3D pattern formation within protein-based gel

Modern regenerative medicine is on the lookout for implantable materials that can change as the surrounding tissue does, and two Stanford University researchers have made some new gel materials that do just that. Karin Straley and Professor Sarah Heilshorn have developed a method for preparing protein-based implant materials that can evolve with the changing needs of the host biological system. Not only can their new materials change in different ways at different times, they can do so at different places within the implant materials.

Research suggests that zinc activates a key protein on T cells needed to fight infections

Everyone knows that vitamins "from A to zinc" are important for good health. Now, a new research study in the August 2009 print issue of the Journal of Leukocyte Biology suggests that zinc may be pointing the way to new therapeutic targets for fighting infections.

UV radiation from sunlight may trigger certain autoimmune diseases in women

Ultraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women, according to a study by researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health.

Protein level may predict severe osteoarthritis

Osteoarthritis (OA), the most common joint disorder throughout the world and a leading cause of disability, is characterized by pain, impaired joint mobility, reduction of muscular strength and loss of joint function. Unlike most other common diseases, little is known about its origins, and factors predicting a severe disease course have not been identified.

Mathematical modeling predicts Herceptin resistance

Cancer researchers are turning to mathematical models to help answer important clinical questions, and a new paper in Cancer Research, a journal of the American Association for Cancer Research, illustrates how the technique may answer questions about Herceptin resistance.

Scientists re-engineer human enzyme to become resistant to harmful agents such as chemotherapy

Scientists from the Université de Montréal and McGill University have re-engineered a human enzyme, a protein that accelerates chemical reactions within the human body, to become highly resistant to harmful agents such as chemotherapy, according to a new study published in The Journal of Biological Chemistry.

Research shows why HIV virus is so successful and so deadly

Retroviruses such as HIV that are already within cells are much more easily transmitted when they are next to uninfected cells than if they are floating free in the bloodstream.
