Killing brain tumors from within: A 'Trojan horse' approach

...ors were grown. The tests proved 100% effective in eliminating the tumorous growths. An article on the work of Prof. Levitzki, along with his associate Dr. Shir and Professors Manfred Orgris and Ernst Wagner of Ludwig-Maximilians University in Munich, was published in a recent article in the journal PLOS Med...

Bacterial protein shows promise in treating intestinal parasites

...msters infected with hookworms was as effective in eliminating the parasites, curing anemia and restoring weight gain in the hamsters as mebendazole, one of the drugs currently recommended to treat infections in humans. The scientists also discovered that this protein, called Cry5B, targets both developing, or l...

P(acman) takes a bite out of deciphering Drosophila DNA

...nt gene to go in the genetic blueprint of the fly, eliminating the apples-and-oranges problem. This third technique ?phiC31 ?works also in mouse and human cells, implying that this new technique could be used in those cells as well. ...

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study

... height of grasses, trees or other plants, thereby eliminating the need to constantly manicure gardens. Based on earlier studies, the Salk researchers had developed a model that explained what happens inside a plant cell when brassinolide signals a plant cell to start growing. But a model is just a model. Of...

Salk scientists untangle steroid hormone signaling in plants

Vaccine shown effective against chancroid

... chancroid could shut down the cycle of infection, eliminating the disease of not only sex workers but their sexual partners. And evidence suggests that eliminating chancroid throughout Africa could help reduce the transmission of HIV. "Diverting but a fraction o...

Interfering RNA silences genes in 'slippery' immune cells

...ay allow HIV-infected cells to self-destruct, thus eliminating a hiding place for the virus," said Dr. Finkel. "More broadly," she added, "the technique could theoretically be directed against other immune-related diseases, by silencing harmful genes active in T cells." Dr. Finkel's co-authors, all from The ...

Scientists take 'snapshots' of enzyme action

...nd functional mechanism of an enzyme essential for eliminating unwanted, non-nutritional compounds such as drugs, industrial chemicals, and toxic compounds from the body. The detailed mechanism of action will help scientists understand how these compounds are eliminated and what goes wrong in cases where normal ...

Snakes' virtual glasses, leopard spots and all-optical transistors

...tive performance, there are additional benefits to eliminating calculation-crammed test booklets. Multiple choice tests ease grading demands in large classes, reduce grading ambiguity and inconsistencies between graders, and severely cut back on the numbers of students contesting grades. While standardized test ...

The molecular mechanism of a diabetes vaccine revealed

...roducing pancreatic cells, reducing and ultimately eliminating the production of insulin ?a hormone needed to convert sugar, starches, and other foods into energy. Several years ago, Prof. Cohen and colleagues developed a vaccine that arrests the progression of Type 1 diabetes in laboratory animals. They had di...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...ter, needed by the cell to stay alive. Further, by eliminating stresses ordinarily caused by drying, the nanostructure forms without fine-line cracks. These improvements help maintain the functionality of the cell and the accessibility of its surface. By comparison, the more common practice of merely 'trapping...

Device effective in zapping the pain out of migraines

...the experimental device appears to be effective in eliminating the headache when administered during the onset of the migraine. The study, led by the Ohio State University Medical Center neurology investigators, was presented Thursday (6/22) at the annual American Headache Society meeting in Los Angeles . A ...

Research identifies protein in mice that regulates bone formation

...chool of Public Health (HSPH) have discovered that eliminating a protein, Schnurri-3 (Shn3), in mice led to profound increases in bone mass throughout their skeletal system. The results may have implications for the treatment of osteoporosis. The study was published in the May 26 edition of Science ( http://www....

Radiation-killed bacteria vaccine induces broad immune response in mice

...tituted just before use, explains Dr. Raz, thereby eliminating the cold chain requirement. It is also possible that a strategy based on irradiation-inactivated whole pathogens could rapidly yield vaccines against such bacterial diseases as typhoid, cholera, tuberculosis and other diseases of public health co...

New pathways for autoimmune treatment identified

...ells that are dysfunctional. Negative selection is eliminating T-cells that recognize the body's own proteins, Dr. She says. Other researchers recently confirmed that the Aire gene is involved in negative selection by controlling some protein expression in the thymus, Dr. Mi says. The thymus is supposed to expr...

New protein target may advance design of HIV and cancer drugs

...er affinity for the protein peptide backbone, thus eliminating the zinc from its active site. In the specific case discussed in the paper, the HIV NCp7 protein is responsible for the proliferation of the HIV virus. If researchers can inhibit the action of this zinc finger protein, they can stop the spread of th...
