Emory Study Tests Bone Marrow Stem Cells to Improve Circulation in Legs

Physicians at Emory University School ofMedicine are conducting a clinical trial using stem cells generatedwithin the bone marrow to grow new blood vessels that could improvecirculation in patients with blockages in the arteries of their legs --a condition called (PVD). Individuals with PVD...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

In a new study, researchers present a “cautionary tale?about what may go wrong when using the fledgling science of proteomics to devise a diagnostic test for cancer. In the February 16 issue of the Journal of the National Cancer Institute, researchers from The University of Texas M. D. Anderson Cancer Center detail why an experimental test intended to identify early ovarian cancer from a...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

A molecule designed to block cat allergies successfully prevented allergic reactions in laboratory mice, as well as in human cells in a test tube, University of California, Los Angeles (UCLA) researchers report in the April issue of Nature Medicine, available online now. In the future, the investigators say, these promising results could lead to a new therapy not only for human cat allergies, but...

Scientists develop new color-coded test for protein folding

Every protein--from albumin to testosterone --is folded into a unique, three-dimensional shape that allows it to function properly. Now Stanford University scientists have developed a simple test that instantly changes color when a protein molecule attached to a gold nanoparticle folds or unfolds. The new technique, which works on the sa...

Highly adaptable genome in gut bacterium key to intestinal health

A bacterium that lives in the human gut adaptively shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates. This adaptive mechanism not only allows the bacterial species to survive rapidly changing nutrient conditions but also helps maintain the functions and stability of the gut's highly complex microbial society, according...

First Vaccine Designed for Africa Cleared for Testing in Humans

The first AIDS vaccine candidate designed specifically for Africa will enter human trials this summer. The International AIDS Vaccine Initiative (IAVI) announced on July 11 at the 13th International AIDS Conference in Durban, South Africa, that the Medicines Control Agency (MCA) of the United Kingdom has approved Phase I testing of a DNA vaccine based on HIV subtype A, the most commo...

Laboratory Testing Can Identify Risk of Pre-Term Labor and Delivery

A test for fetal fibronectin can predict whether a pregnant woman is at risk for early labor and delivery. Those at high risk for pre-term births are women with previous pre-term deliveries, those with multiple gestation pregnancy, and those who suffer from diabetes and/or hypertension. The current approach for finding whether a woman will go into premature labor is the use of a clinical...

Long-Term Survival can be Predicted by a Simple Lung Test

Researchers have found a simple pulmonary test can predict overall long-term survival rates in both men and women. Their findings are presented in the September issue of Chest. Researchers studied survival rates based on a lung function test, called forced expiratory volume in one second (FEV1).They performed the lung function test on a group of more than 550 men and more than 640 wom...

More Accurate "PROSTATE CANCER" Test can save Unnecessary Biopsies

Prostate cancer can effect men over the age of 40 years and is the second commonest cancer among men after lung cancer. Usually it goes undetected till it is advanced and beyond cure.
