Use Of Protease Inhibitors For HIV Associated With Dramatic Rise In Oral Warts
While the main oral infections associated with HIV infection and AIDS have been brought under control, the use of powerful new protease inhibitors to treat HIV has led to a dramatic, unexplained increase in oral warts among patients, a new study reveals.

Bone Marrow Transplants May Be Improved Thanks To Discovery Of Mechanism Underlying Human Stem Cell Migration
Weizmann Institute has discovered a key mechanism of stem cell migration that may lead to significantly improved bone marrow transplants, as reported in the February 5 issue of Science.

Researchers Making Methane More Marketable
Researchers at Michigan Tech are hoping a new process they developed for creating liquid methanol from methane will open the door for greater commercial use of this plentiful gas.

An Expedition Of Genetic Proportions Leads Duke Researcher To A New Culprit In Lung Cancer Metastasis
Mapping the human genome isn't his job, but Dr. Gerold Bepler, a researcher at Duke University Medical Center, has tackled part of it anyway.

Repairing Stroke-Induced Brain Damage May Be Possible Through Brain Cell Transplantation
Researchers who have pioneered a technique of transplanting laboratory-grown neuronal cells into the brains of stroke patients say that the procedure has been performed in seven patients, and some of those patients report that the therapy may have helped to restore motor and speech skills that otherwise would have been lost forever.

UCSF/Gladstone Finding May Explain HIV'S Ability To Infect Cells Lacking The Key Target Of HIV: The CD4 Receptor
Researchers may have identified the molecular mechanism that enables HIV to cast its infectious net beyond those cells bearing the CD4 receptor, the loading dock that HIV normally first engages on a cell's surface.

Boom Doom Looms: Millions Of "Poor, Frail Older Americans" Foreseen
Unless more resources than the current $1 billion per year are devoted to research and prevention of the diseases of aging, the next millennium will be characterized by millions of poor and frail older Americans, a gerontologist warns.

UCSF Researchers Pinpoint Molecule That Triggers Deadly Progress Of Pulmonary Fibrosis
Scientists have uncovered crucial steps in a grim molecular dance that asphyxiates more than 5,000 people a year in the United States.

U.S. Natural Disaster Planning Bit Of Disaster Itself, Study Finds
CHAPEL HILL -- When University of North Carolina at Chapel Hill professor David Godschalk and colleagues agreed to conduct the first complete study of how the nation's 11-year- old basic natural disaster law was being implemented, they expected to discover both poor and good planning.

UCSF Researchers Identify Key Genes In Bone Healing Process That Could Lead To New, Molecular-Based Treatments
Researchers from the University of California San Francisco studying bone healing in animal models have found that two genes essential for bone formation in the fetus are also key to successful fracture repair in the adult.

Aerogel Rides Again
Aerogel will take its next ride into space on Stardust, launching this weekend.

A Real Smart Asp: Snakes Show Surprising Ability To Learn
A University of Rochester neuroscientist has found that snakes have a much greater capacity for learning than most earlier studies have indicated.

Arctic indigenous leaders, scientists to study reindeer and caribou systems
Indigenous leaders, reindeer herders, caribou hunters, scientists and policy makers from ten countries will gather next week (February 10 - 14) in Rovaniemi, Finland to discuss the role of humans in managing and protecting reindeer and caribou, the most important land-based species for people living in the Arctic.

Research Shows Wrong Activity Worse Than No Activity In Developing Brain
New research reported in the Jan. 28 issue of Nature provides insights into a fundamental part of normal brain development.

Researchers Identify Molecular Site That Is Key To HIV's Ability To Infect Cells Of Brain, Colon
Researchers have determined that HIV infects cells of the brain and colon by binding with a particular co-receptor, CCR5, located on the surface of some, but not all, cells targeted by HIV.

Wine Drinkers Consume Heart-Smart Diets
Several previous studies have touted the benefits of drinking wine to prevent heart disease-a concept known as the

AIDS Virus May Evolve Differently In Cerebrospinal Fluid Compared With Blood In Some Patients, UCSF/Gladstone Research Finds
Genetic analysis and clinical studies have revealed that the AIDS virus in the cerebrospinal fluid (CSF) of some people with AIDS-related dementia evolves independently of the virus in their blood, leading to two genetically distinct forms of the virus.

Earlier Detection Of Infant Cataracts Needed
In twenty-nine per cent of cases, infant congenital and infantile cataracts are not detected by health professionals before the age of one year, despite current UK recommendations to routinely examine newborn babies, says a study in this week's BMJ carried out through the British Congenital Cataract Interest Group.

Do Varicose Veins Have Symptoms?
In this week's BMJ Andrew Bradbury and colleagues at the University of Edinburgh, along with researchers at the Edinburgh Royal Infirmary, report that symptoms including heaviness, swelling, cramps and tingling in the legs are extremely common in the general population whether or not varicose veins are present.

UF Team Achieves Milestone In Design Of New Semiconductors
Using a material called gallium nitride a group of University of Florida engineers is the first to develop an important building block for a new breed of electronic switches likely to provide smooth, uninterrupted electricity in the coming era of utility deregulation.

Life Among Dead Brain Cells: Discovery Could Help Improve Memory Capacity Of Stroke Victims
For years, scientists have believed that brain cells can't be born or newly generated following a stroke.

Do Post-Menopausal Women Really Need Cervical Smear Tests?
In this week's BMJ, Chris Sherlaw-Johnson and colleagues from University College London and Queen's Medical Centre, Nottingham use a mathematical model to assess whether post- menopausal women who are at little risk of developing cervical cancer could be safely removed from the screening programme.

Radioactive Beads Latest Weapon In Fighting Cancer In Dogs, Cats
When surgery can't be performed or isn't enough to remove cancerous tumors, veterinarians at Kansas State University's College of Veterinary Medicine are using a new, implantable radiation treatment option.
