...stics of the disease, so they will probably not be appropriate for direct use in treating patients. In addition, researchers must develop methods to efficiently direct the differentiation of embryonic stem cells to specific stable cell types. Scientists must also find a way to remove the remaining animal compone...

A new way to share models of biological systems

...e components of models, and helps them to retrieve appropriate models, which they can then visualize and build upon using any SBML-compatible software. "Ultimately," says Le Novère, "we hope that publishers will encourage any author who plans to publish a new model to submit it to the BioModels database; this w...

Where bacteria get their genes

...es of Streptococcus and can therefore prescribe an appropriate antibiotic. If you couldn't classify bacteria because they have genes from all over, doctors wouldn't be able to do this."

Analysis Of Human Genome To Predict The Development Of Illnesses

...of the sickness using the gathered data. Using the appropriate analyses, it enables the measurement of the efficiency of and patient response to the different treatments administered, thus enabling the identification of new, more effective therapeutic targets. This new tool is available on Internet, thus enabli...

Active Vaccine Prevents Mice From Developing Prion Disease

"These technical issues are not major hurdles," says Dr. Wisniewski. "Developing a marketable vaccine for livestock is something that is very achievable." The aut...

Stem cell treatment improves mobility after spinal cord injury

...o full-grown oligodendrocyte cells and migrated to appropriate neuronal sites within the spinal cord. In the rats treated seven days after the injury, myelin tissue formed as the oligodendrocyte cells wrapped around damaged neurons in the spinal cord. Within two months, these rats began to show significant impr...

Random gene expression may drive HIV into hiding

...ferent qualitative behaviors," said Arkin. If the appropriate modifications take place, then the HIV genome is transcribed and the positive feedback loop kicks in. If these Tat modifications don't happen, then HIV ceases to be expressed, and the cell can then possibly enter a latent state. The significance of ...

Four cases of polio were confirmed on 20 April in just one governorate in the south-western part of the country, on the Red Sea coast. The latest 18 cases occurred across five governorates throughout Yemen, inc...

Bees, Brains and Addiction

Computer models of how a bee assimilates and responds to information about a reward can be then applied to studies of how humans make decisions about rewards.

Environmental chemical cocktail may sabotage sperm

"The sperm were still alive and their ability to move was unaffected, but the spontaneous acrosome reaction meant that they were unable to f...

The Johns Hopkins researchers have found that this advice is delivered by a sequence of chemical reactions called the "JAK/STAT" pathway.

Researchers seek to discover what really happens when a virus enters the body

And as NIH's Matzinger says, knowing what initiates an immune response will affect and, researchers hope, improve medical treatment. Bell is an associate membe...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

Finally, studies need to be conducted to demonstrate that giving pregnant women higher levels of vitamin C will not itself cause development problems. The ONPRC is a registered research institution, inspected regularly b...

Novel mechanism for DNA replication discovered

In other words, if a guanine base is on the original strand of DNA then its partner, a cytosine base, will pair to it on the replicated strand. In a study published in this week's issue of Science, researchers from Mount Si...
