Grapes inhibit cancer growth

Components in grapes, including some newly identified ones, work together to dramatically inhibit an enzyme crucial to the proliferation of cancer cells, say scientists at the University of Illinois at Urbana-Champaign.

No serious adverse events found with next-generation smallpox vaccine

Interim data from a phase I/II clinical trial of a next-generation vaccine for smallpox suggest that the vaccine may provide immunity and thus far the trial has been without any serious adverse events.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Scientists have replicated hepatitis C virus (HCV) in the laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV.

Differing forms of taste genes mean that we all live in our own unique taste world

A study published in the February 22 issue of Current Biology confirms the influential role of genetics in determining the wide range of human sensitivity to taste, ultimately impacting how we each perceive the world in a slightly different way.

Discovery of gene related to p53 called Bnip3L that can also cause cell death

Researchers have known for a decade that the p53 tumor suppressor gene is important for killing cells as they proliferate under low-oxygen conditions inside tumors.

Novel approach to bioengineer artificial skin for burn victims

Each year more than 45,000 Americans suffer burns serious enough to require a hospital stay, according to the American Burn Association. While the traditional therapy of using skin grafts to cover burn sites has improved, a number of problems including scarring, infection and poor adhesion remain.

Exposure to the chemical BPA (Bisphenol A) stimulates prostate cancer cell growth

An estrogen-like chemical commonly used to synthesize plastic food containers has been shown to encourage the growth of a specific category of prostate cancer cell, potentially affecting the treatment efficacy for a subset of prostate cancers.

Stress affects molecules believed to play a key role in cellular aging

There have been many studies that have shown that your health is greatly affected by how you react to stressful events in life-setbacks or deadlines at work, conflicts and losses at home.

Scientists have given blind nerve cells the ability to detect light

Scientists at the University of California, Berkeley, have given "blind" nerve cells the ability to detect light, paving the way for an innovative therapy that could restore sight to those who have lost it through disease.

Cells linked to asthma and eczema also help cure deadly illness in mice

Mast cells are immune cells known mostly for their unwanted effects: they cause the wheezing of asthma, the itching of eczema, the sneezing and runny nose of hay fever and, in extreme cases, the life-threatening shock of anaphylaxis.

The Bush Medicare Prescription has changed the identity of medical oncology

Under previous law, Medicare covered chemotherapy as well as radiation treatment for cancer patients, but did not pay for oral-dose anti-cancer drugs, unless they were available in both oral and injectable form.

Evidence links cellular iron deficiency to restless legs syndrome

Iron-deficient cells in the brain are mixing up central nervous system signals to the legs and arms causing the irresistible urges to move and creepy-crawly sensations that characterize restless legs syndrome (RLS), a Penn State College of Medicine study reports.

Findings could lead to improvements in the next generation of implantable cardioverter defibrillators

For people who suffer from a rapid heartbeat condition called tachycardia, an implanted device can usually nudge the racing blood pump back into a normal rhythm by applying electrical pulses to the heart.
