New findings challenge one of the established views of how nerve cells communicate with one another

Every time we move, feel emotions, think or remember, the nerve cells, or neurons, in our body transmit messages to one another via chemical signals called neurotransmitters. Within neurons are tiny organelles called synaptic vesicles that sequester neurotransmitters and release them when needed into the synapse, or space between nerve cells, where the chemical signal is transmitted to other neurons.

EuroVacc 02 HIV Vaccine trial begins

The European Vaccine Effort against HIV/AIDS, has announced that a phase I clinical trial of novel investigational vaccines comprising DNA-HIV-C and NYVAC-HIV-C for the prevention of HIV infection has started in Lausanne and London in February 2005.

Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

New technique to identify fetal genetic material from amniotic fluid

A preliminary report suggests that cell-free fetal messenger RNA (ribonucleic acid) can be extracted from amniotic fluid (fluid around the fetus), and then be analyzed to study gene expression changes that may reflect the well-being of the fetus, according to a paper in the February 16 issue of JAMA, a theme issue on medical applications of biotechnology.

New report detailing how animal experiments misled scientists on Vioxx

Tommorow, February 17, John J. Pippin, M.D., FA.C.C., will testify before Food and Drug Administration (FDA) officials and present a new report detailing how experiments on mice, dogs, and other animals misled scientists and ultimately contributed to a tragic outcome for human patients exposed to Vioxx and other drugs.

Angiogenesis inhibitor molecules defend against the development and spread of cancer

Research led by investigators at Beth Israel Deaconess Medical Center (BIDMC) helps explain how a group of angiogenesis inhibitor molecules serve as an important defense mechanism against the development and spread of cancer, offering key insights into why cancerous tumors grow at different rates among different individuals.

Exposure of expectant mothers to urban air pollution may alter the structure of babies' chromosomes while in the womb

A new study of 60 newborns in New York City reveals that exposure of expectant mothers to combustion-related urban air pollution may alter the structure of babies' chromosomes while in the womb.

Discovery may have implications for the treatment of hemophilia A and B

University of North Carolina at Chapel Hill researchers have made a discovery that may have implications for the treatment of liver-based genetic defects such as hemophilia A and B in humans.

Blocking estrogen may be vitally important to improving survival from lung cancer

New and effective treatments for lung cancer may rest on their ability to hinder the action of estrogen in lung cancer cells, according to two studies published in the current issue of Cancer Research.

Green tea extract has potential as an anti-cancer agent

A new study on bladder cancer cells lines shows that green tea extract has potential as an anti-cancer agent, proving for the first time that it is able to target cancer cells while leaving healthy cells alone.

Mesoblast signs adult stem cells agreement

Australia’s adult stem cell company, Mesoblast Limited, today announced that it had signed an agreement for production of specialised adult stem cells, known as Mesenchymal Precursor Cells (MPCs), to be used in human pilot clinical trials in patients with orthopaedic and cardiovascular diseases.

Novel approach to treating hearing loss

GenVec today reported that encouraging preclinical findings on a novel approach to treating hearing loss have been published in the March 2005 issue of Nature Medicine.

Under-active thyroid associated with reduced breast cancer risk

Researchers at The University of Texas M. D. Anderson Cancer Center have found that women with a common thyroid gland disorder appear to have a reduced chance of developing invasive breast cancer, according to a study published in the March 15 issue of Cancer, out online Feb. 14.

Paradox suggests reasons why COX-2 inhibitors hurt and help

Laboratory studies at Johns Hopkins have revealed that certain products of the enzymes COX-1 and COX-2 can both protect and damage the brain. The findings, published in the February 2005 issue of the Journal of Neurochemistry, offer tantalizing clues to why drugs like Vioxx and Celebrex, which block COX-2, can ease arthritis but potentially harm the heart and brain.

Key insight into the process of normal synapse development may lead to improved treatment of conditions such as drug addiction and epilepsy

Communication in the brain travels from one nerve cell to another through critical connections called synapses. These neuron-to-neuron junctions form early in brain development, and their construction was thought to be guided by the nerve cells themselves.

New way of transporting medicines into the brain

Dutch researcher Corine Visser investigated a new way of transporting medicines into the brain. Her approach made use of an iron transport system located on the blood-brain barrier. The smaller the medicine, the more easily it penetrates the brain.
