Gene variations explain drug dose required to control seizures

Determining which variants of particular genes patients with epilepsy carry might enable doctors to better predict the dose of drugs necessary to control their seizures, suggest basic findings by researchers at the Duke University Institute for Genome Sciences & Policy (IGSP) and the University College London.

Tool reliably predicts recovery from coma

A Department of Veterans Affairs and Northwestern University researcher has developed the first reliable measure of neurobehavioral functioning that will help physicians predict the likelihood of a patient recovering consciousness during coma from severe brain injury within the first year of injury--with up to 86 percent certainty.

Patients with Hepatitis C have a significant decrease in their health-related quality-of-life

Patients with Hepatitis C virus (HCV) have a significant decrease in their health-related quality-of-life (HRQOL), although treatment success can mitigate this negative effect.

Statins appear to be safe for people with fatty liver disease

Statins appear to be safe for people with fatty liver disease who could benefit from their cholesterol-lowering capabilities, concludes a review paper published in the April 2005 issue of Hepatology, the official journal of the American Association for the Study of Liver Diseases (AASLD).

Variation in the gene ENPP1 may predict risk for diabetes

A particular gene variant that could serve as a predictor for type 2 diabetes has been identified by researchers at UT Southwestern Medical Center.

Researchers have identified the proteins that allow specific brain cells to "change channels"

Johns Hopkins researchers have identified the proteins that allow specific brain cells to "change channels," a rare ability that tweaks what can come into the cell. The findings, described in the March 24 issue of Neuron, might let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease.

Vital molecular step in cell migration

A vital molecular step in cell migration, the movement of cells within the body during growth, tissue repair and the body's immune response to invading pathogens, has been demonstrated by researchers in the University of California, San Diego (UCSD) School of Medicine.

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.

Important that menopause not viewed as a disease

An independent panel convened last week by the National Institutes of Health found that many women move through the menopausal transition with few disabling symptoms, and that it is important that menopause not be viewed as a disease.

Gene/yeast finding links processes in heart disease and cancer

By studying a little-known yeast too primitive to get diseases, Johns Hopkins researchers have uncovered a surprising link between two processes at play in heart disease and cancer in people.

Molecule that causes secondary stroke

Scientists at the University of Cincinnati (UC) College of Medicine have discovered the cause of a deadly type of secondary stroke known as cerebral vasospasm.

Benefits of lung cancer screening with CT questioned

Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.

Research tool for turning off genes may eventually have therapeutic application

A research team based at Massachusetts General Hospital (MGH) has identified 80 new genes essential to the process of RNA interference (RNAi), a powerful new research tool for inactivating genes in plants or animals.

Marburg death toll in Angola now up to 122

Carlos Alberto, a spokesman for the Angolan health ministry, says the death toll in the Marburg hemorrhagic fever outbreak in Angola has now risen to 122, just one fewer than in the largest previous outbreak of the disease, in the Democratic Republic of the Congo from 1998 to 200 and killed 123 of 149 people infected.

Use of DNA-damaging agents revolutionizes chemotherapy against a wide variety of cancers

A new study demonstrates the potential effectiveness of treating tumors by combining agents that damage DNA with a drug that sensitizes cancer cells to these agents.

Three different leukemias are all caused by mutations that alter a specific enzyme controlling blood cell proliferation

Identifying the genetic malfunction that causes these disorders raises the hope that researchers may be able to devise a targeted therapy, just as they have done for chronic myelogenous leukemia (CML), which is presently treated with Gleevec. The three leukemias that share a common genetic cause are polycythemia vera (PV), essential thrombocythemia (ET) and myeloid metaplasia with myelofibrosis (MMM).

Test that will prevent the needless loss of the thyroid gland in people with the noncancerous condition

New research suggests that physicians can distinguish between a type of thyroid cancer and an identical-looking, non-cancerous thyroid condition by simply determining the activity of three genes.

E. coli petting zoo link in Florida

A 12-year-old girl's death is being investigated for possible links to an outbreak of E. coli bacterial infections among people who attended one of two fairs in early March that included petting zoos, the Strawberry Festival in Plant City and the Central Florida Fair in Orlando.

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.

New therapy for treating cat allergies looks promising

Andrew Saxon, M.D., and a team of researchers at University of California, Los Angeles (UCLA) have found that a molecule designed to block cat allergies can prevent allergic reactions in laboratory mice and was also successful when tested on human cells in a test tube.
