Stressgen granted new U.S. patent for treatment of Hepatitis B

Stressgen Biotechnologies announced today that the U.S. Patent and Trademark Office granted Patent Number 6,921,534 covering fusion protein compositions comprised of a hepatitis B virus (HBV) antigen fused to a heat shock protein (Hsp), as well as DNA encoding such fusion proteins, and methods of treating an HBV infection using these fusion proteins.

Researchers develop screening test for cells that activate immune system

UT Southwestern Medical Center researchers are the first to create a large-scale, cell-based screening method that identifies which compounds activate immune-response cells that hold promise for future cancer-fighting vaccines.

Call for more donations of brains to help researchers discover new treatments for neurological disorders

Speaking at the BA Festival of Science, at Trinity College, Dublin, Dr Kirstin Goldring from Imperial College London and Charing Cross Hospital is calling for more donations of brains to help researchers discover new treatments for neurological disorders.

Methoxychlor (MXC) may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women

The researchers found that MXC, which was manufactured as a safer replacement for the now-banned DDT, alters the estrogen-regulated gene Hoxa10 in the reproductive tract and reduces the ability of the uterus to support embryo implantation. The researchers used mice and then human cell lines to confirm their findings.

Researchers uncover how the inhaled form of anthrax disarms bacteria-fighting white blood cells before they can fend off the disease

The lethal toxin in anthrax paralyzes neutrophils, the white blood cells that act as the body's first defense against infection, by impairing how they build tiny filaments that allow them to crawl throughout the body and eat invading bacteria.

Researchers to study information technology impact on children

Michigan State University researchers will use a $750,000 grant from the National Science Foundation to better understand the nature and extent of children's information technology (IT) use and how using IT is affecting them.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Chinese scientists clone a goat

It was released on August 24, 2005 by Prof. Chen Dayuan (Da-Yuan Chen) from the CAS Institute of Zoology that the first success in cloning Asian Yellow Goat by nuclear transfer had recently been achieved in east China's Shandong Province.

DNA research: learning the language of genes

Griffith University's Dr Christine Wells is one of just a handful of women scientists in the global FANTOM consortium which has announced a major breakthrough in unraveling the mammalian genome.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

Giving patients both chemotherapy and radiation in the beginning of treatment may help cancer patients live longer

While researchers have learned in the last decade that combining chemotherapy with radiation is better than radiation alone for treating non-small cell lung cancer patients with locally advanced disease - cancer confined to the lungs - finding the right combination of drugs - and the best timing of treatment - has been tricky.

Immune cells known as macrophages linked to growth of lymph vessels in eyes,

Scientists at Schepens Eye Research Institute have discovered that a particular immune cell contributes to the growth of new lymph vessels, which aid in healing. This cell, known as a macrophage, is called in by the body during the wound healing process.

Double whammy of vitamin D and anti-inflammatory zaps prostate cancer cells

Scientists from Stanford University say they have discovered that vitamin D, known as the "sunshine vitamin,"can limit the growth of prostate cancer cells when combined with non-steroidal anti-inflammatory drugs.

New way to assess risk of breast cancer recurrence

Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast.

Gene B-myb essential in preventing tumors

A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors.

Single molecular anchor holds the key to treating many types of bacterial meningitis

By blocking the molecule's anchoring ability, researchers may be able to find a way to stave off the most common serious infection of the central nervous system and a major cause of childhood death and disability. The researchers' findings appear in the September 2005 issue of the Journal of Clinical Investigation.

New vaccine with the potential to protect against fungal pathogens

A group of scientists in Italy have developed a vaccine with the potential to protect against fungal pathogens that commonly infect humans, according to a study by Torosantucci and colleagues in the September 5 issue of The Journal of Experimental Medicine.
