New drug will help fight against superbugs

In the fight against the infections invading hospitals both sides of the globe, scientists have developed a drug that destroys the defences of superbugs, raising hopes it could help quell the rampant and often lethal outbreaks that continue to strike hospitals.

Naturally occurring peptide hormones - candidates for the treatment of cancer, sexual dysfunction, eating disorders

Chemists at the University of Arizona have developed modified versions of naturally occurring peptide hormones that could be key to novel treatments of a variety of diseases, including eating disorders (anorexia, obesity), diabetes, sexual dysfunction and skin cancer.

Molecular switch that turns on the production of myelin

Scientists at New York University School of Medicine report in a new study that they have identified the molecular switch that turns on the production of myelin, the fatty insulation around nerve cells that ensures swift and efficient communication in the nervous system.

Potential new way to fight HIV

Researchers have confirmed for the first time the benefit of an innate defense system present in the few patients who remain healthy after years of infection with HIV despite receiving no treatment, according to an article published in the September edition of the Journal of Virology.

C. elegans worm provides clues to dealing with human disease

A step towards understanding cell mutations that cause a variety of human diseases, particularly in children -- including that which brings about premature aging and early death -- has been taken by researchers at the Hebrew University of Jerusalem Silberman Institute of Life Sciences and the John Hopkins University School of Medicine.

Researchers link individual preferences to neuronal activity in brain

Life is full of choices. But how do individuals know what their preferences are and how do they act on them? And what leads mothers to make choices that benefit or lead to neglect of her offspring? Based on research performed using laboratory rats, a team of neuroscience researchers at Rutgers University-Newark suggest that an intricate system exists within the brain for establishing individual preferences, which ultimately impacts choices.

Prostate cancer manipulates an important group of signaling proteins called Wnts to establish itself in bone

Prostate cancer is a cruel disease. Left untreated, prostate cancer cells often metastasize, or spread, to bone where they form fracture-prone tumors that are extremely painful.

More than 15 percent of our genes are mobilized to defend against microbial attacks

The body's overwhelming genetic defense, which has implications for the survival of patients who are severely burned or injured, was revealed in a sweeping analysis of gene activity in volunteers who were injected with a bacterial product that temporarily created flu-like symptoms.

Low doses of the active form of vitamin D and non-steroidal anti-inflammatory drugs form one-two punch against prostate cancer cells

Low doses of the active form of vitamin D and non-steroidal anti-inflammatory drugs, taken in combination, have been shown to act as a powerful one-two punch that knocks down the growth of prostate cancer cells.

When it comes to inflammation, too much of a good thing can be deadly

In some severely injured patients, this normal healing process can develop into a lethal, whole-body response, including bloodstream infection (sepsis) and multiple organ failure. How and why inflammation turns from healing to harming is still mysterious, so doctors can't accurately predict how each injured patient will fare.

Designer molecules that combine metals such as copper with natural organic materials could treat diseases in the body

That's the finding of chemists at Ohio State University, who have successfully tested such molecules against portions of HIV and Hepatitis C virus RNA in the laboratory. They've also created molecules that act like ACE, or angiotensin-converting enzyme, inhibitors - drugs that are used to lower blood pressure.

Toxic flame retardants known as PBDEs are becoming a major environmental health concern

An analysis of persistent chemicals in the breastmilk of Pacific Northwest mothers, released today at an international scientific conference in Toronto, “Dioxin 2005,” found that levels of the toxic flame retardants PBDEs may be overtaking those of PCBs, an industrial chemical banned in the late 1970s.

Asian bird flu expert joins Murdoch University

Murdoch University's School of Veterinary and Biomedical Sciences have appointed Dr Trevor Ellis, an expert in Asian Bird flu, SARS and Foot and Mouth Disease.

Good old fashioned soap and water the answer for "superbug"

Superbugs are bacteria that have mutated to become resistant to common antibiotics which are no longer any use against them.

New treatment can zap cancer cells and avoid healthy tissue

Australian researchers say they have developed a cancer treatment which can identify and kill individual cancer cells.

Blocking Hutchinson-Gilford progeria syndrome (HGPS) with anticancer drugs

A class of anticancer drugs currently being evaluated in phase 3 clinical trials may also be an effective treatment for Hutchinson-Gilford progeria syndrome (HGPS), a fatal genetic disorder that causes premature aging.

Three-dimensional molecular structure of a promising malaria-vaccine component

An international team of scientists that includes a researcher from the U.S. Department of Energy's Brookhaven National Laboratory has determined the three-dimensional molecular structure of a promising malaria-vaccine component.

Drugs known as farnesyltransferase inhibitors (FTIs) may hold promise for premature aging disorder

In a surprising development, a research team led by the National Human Genome Research Institute (NHGRI), has found that a class of experimental anti-cancer drugs also shows promise in laboratory studies for treating a fatal genetic disorder that causes premature aging.
