Transplantation Of Monkey Embryonic Stem Cells Reverses Parkinson Disease In Primates

...d for that survival to be long lasting in order to render thisapproach as a useful therapy in humans.Langston highlights that "clearly the study reported here will advanceresearch aimed at validating the use of stem cells to treatneurodegenerative disease" and this is most welcome particularly asinvestigato...

Gene variations explain drug dose required to control seizures

...s with long-term drug side effects that eventually render the disease untreatable, he said. Patients' genetic makeup might also influence the dose of chemotherapy needed to successfully fight a tumor, while minimizing often intolerable side effects. ...

UCSD research reveals mechanism involved with type of fatal epilepsy

...s with Lafora disease have mutations in malin that render it unable to mark laforin for degradation. This increase in laforin may lead to Lafora disease through aberrant glycogen metabolism. This work establishes a few testable models as to the molecular mechanism of the disease. Dixon and colleagues are c...

Rhesus monkeys can assess the visual perspective of others when competing for food

...ow exactly how blocking or averting one's eyes can render one unable to see. Thus, even without any training, these monkeys were able to accurately consider the visual perspective of others when deciding from whom to steal. In previous studies, rhesus monkeys (and other primates) were thought to do no more...

Map of life on Earth could be used on Mars

...rsity in St. Louis is developing new techniques to render a more coherent story of how primitive life arose and diverged on Earth ?with implications for Mars. Carrine Blank Ph.D., Washington University assistant professor of earth and planetary sciences in Arts & Sciences, has some insight concerning te...

Redesigned protein accelerates blood clotting

...no factor VIII suffer severe immune reactions that render the treatment inactive. In addition, current treatment costs as much as $200,000 per patient per year. Researchers at the University of Rochester Medical Center have been studying the structure of factor VIII for 20 years, and are making subtle chang...

Researchers find how some antibiotics kill bacteria

...icrobiology at Ohio State. "Those mutations could render these antibiotics ineffective against most of the serious health threats that they are being used to manage," he continued. All rifamycins belong to one of two structural classes. The researchers used two clinically important rifamycins ?rifapentin ...

Micro RNAs play role in egg making

...protein-making machinery, and their shutdown would render cells unable to produce new proteins. The investigators also found that miRNAs appear to attenuate protein turnover. They speculate that this function may allow a developing egg to accumulate large amounts of specific proteins necessary to drive the...

Human brain is still evolving

... In humans, mutations in either of these genes can render the gene nonfunctional and cause microcephaly - a clinical syndrome in which the brain develops to a much smaller size than normal. In earlier studies of non-human primates and humans, Lahn and his colleagues determined that both Microcephalin and A...

Modifications render carbon nanotubes nontoxic

...d elsewhere have developed processing methods that render nanotubes soluble. In particular, scientists are keen to exploit the fluorescent properties of carbon nanotubes for medical diagnostics. Nanotubes are long, hollow molecules of pure carbon with walls just one atom thick. They are related to buckybal...

Predicting success

...pressure in cancer tissues is at levels that could render chemotherapy ineffective. Their research, which led to the method, was done with MRI equipment similar to that found in hospitals and clinics. A contrast agent often employed in MRI was used as a stand-in for chemotherapy drugs, and this material was...

Study suggests that publicly available genome data may contain small but significant errors

...ways that the two types of data can be combined to render increased confidence levels of the assembly. This physical mapping technology is simple to implement and is relatively inexpensive. It is likely to have significant commercial impact through disease-related genetics studies, such as cancer and au...

Protein translation in sperm

... sperm, collectively known as "capacitation," that render the sperm competent to penetrate and fertilize the female oocyte. In their new report, Drs. Gur and Breitbart demonstrate that human, rat, bovine and mouse sperm all incorporate labeled amino acids into polypeptides during the capacitation phase. T...

Less is more, gene study shows

...anzees and also had mutations in places that would render the human versions inactive. They ended up with 67 human-specific pseudogenes, to which they added 13 that had been reported in the literature but not included in the original database, bringing the total to 80. Next, Zhang and his team consulted a...

High-resolution light microscope reveals the fundamental mechanisms of nerve communication

...ult to efficiently label the proteins of a cell to render them visible with an electron microscope. Moreover, electron beams are only able to penetrate the first several micrometers of a biological sample. For these reasons, among others, despite using electron microscopy for high-resolution cell imaging, m...

Study shows that cells have a natural defense against HIV

... In time, however, HIV can develop mutations that render those drugs ineffective. "Our findings identify a new potential drug target, one that involves a natural host defense," says principal investigator Richard Fishel, professor of molecular virology, immunology and molecular genetics and a researcher ...

Teens unaware of sexually transmitted diseases until they catch one, Carnegie Mellon study finds

...s, for example, cannot be cured. Genital warts can render a woman more susceptible to cervical cancer, and chlamydia can lead to infertility. A 2004 study, involving the same group of adolescent girls, found that those who viewed an interactive sex education DVD created by Carnegie Mellon researchers were ...

Mystery solved: Gold's power against autoimmune diseases defined

...metals, including a special form of gold, that all render MHC class II proteins inactive. In subsequent exp...ents in cell culture, gold compounds were shown to render the immune system antigen presenting cells inactive, further strengthening this connection. These fi...

DOE JGI finishes 100th microbial genome

...t. Those lessons, and how they can be captured to render clean renewable sources of energy and to repair damaged environments, are among the many secrets encoded in their DNA sequence. On May 23, at the general meeting of the American Society of Microbiology (ASM), the U.S. Department of Energy Joint Geno...

Circadian gene helps the brain predict mealtime

...the first evidence that a single gene mutation can render mice totally unable to predict the time of food availability. Studying mice, they found that this lack of food anticipation at both behavioral and physiological levels is specifically associated with a mutation in the Period 2 gene, a gene that previ...
