Motor transport in bio-nano systems

... knowledge that is necessary to improve the system design and to optimize its performance. We now have a ba...omputer simulations. These theories can guide the design of new transport systems by exploring different system architectures in a systematic way before they...

Scripps research scientists identify infertility molecule

...he body, and an important class of targets for the design of drugs. Indeed, about half of the medicines on the market target such GPCRs. In the last few years, Chun and his colleagues have been pursuing basic research on LPA and its receptors to try to understand their roles, particularly in the brain -- l...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

.... In theory, the new research makes it possible to design a pill that will have the same pain relieving effe... the brain's own marijuana-like compounds. "If we design chemicals that tweak the levels of these transmitter substances in the brain," said Piomelli, "we mi...

Scripps research scientists solve structure of a critical innate immune system protein

...as given us great insights into experiments we can design to explore their function. In advance, we wouldn't have known where to look." In addition to helping scientists better understand how TLRs work, the structure may also help scientists take steps toward improving human health, since TLRs are implicat...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...ligand), works with hydrogen peroxide. Its "green" design is based on elements used naturally in biochemistry. Fe-TAMLs were discovered by Collins, whose group has developed an extensive suite of these catalysts to provide clean, safe alternatives to existing industrial practices, as well as ways to remedia...

Study: Harmless virus kills some cancers

... endure for those with cancer." Though similar in design and effectiveness to some gene therapies, Meyers and his team did not modify the AAV2, but left it in its natural form. Therefore, it would not be classified as a gene therapy. Future studies will investigate the precise mechanisms through which AAV...

Disease diagnosis, bioengineering covered at state nano summit

Research into the evolution of protein design by a University of Houston professor will be featured among nearly 20 presentations at the 2005 Nano Summit Research Conference July 28. Kurt L. Krause, an associate professor of biology and biochemistry at UH, will give a presentation at 11 a.m. on...

Compound might defeat African sleeping sickness, clinical trial beginning this month

...lly monitoring the trials," said Olson, who helped design and will oversee the study. She is an infectious disease expert who retired after a long career with Abbott Laboratories. "We're trying to improve the lives of these patients by treating the disease early on in the local villages before it progresse...

Gene expands malaria's invasion options

... The results have important implications for the design of anti-malaria vaccines. The molecule on the parasite that binds to sialic acid receptors on host cells is considered a target in anti-malaria medications, but Cowman notes that if only that gene is blocked, some parasites can still use PfRh4 to swi...

Fragment of yellow fever virus may hold key to safer vaccine

...ly, he said, the findings could help manufacturers design a more consistent vaccine based on recombinant genetic technology, without the potential side effects from variations of the weakened virus strain now grown in fertilized chicken eggs. ...

Redesigned protein accelerates blood clotting

...ective, less burdensome treatment. "We set out to design a version of factor VIII that would improve on the naturally-occurring form of the protein," said Philip Fay, Ph.D., professor in the Department of Biochemistry and Biophysics at the University of Rochester Medical Center, and the study's senior auth...

Snapin: A protein with therapy potential for autism

...ng between the cypin and snapin. This is easier to design and cypin can still function with the other proteins it binds to." Firestein's goal is to build "a core pathway of dendric branching" ?a sequence of steps, each affecting the next, with cypin at the center. "Our pathway says cypin does this; now wha...

Scientists devise way to measure RNA synthesis on the fly in a live cell

...said. In recent years, astronomers have rushed to design experiments that might help them determine what dark matter is made of. "RNA molecules could be called the 'dark matter' of biology," Cluzel said. Biologists have long known that RNA serves as an important intermediary between DNA and the factories ...

Secrets to antibody's success against West Nile Virus surprise scientists

...r results in the Sept. 29 issue of Nature, hope to design a new diagnostic system that can determine whether vaccines for West Nile and related viruses undergoing clinical trials stimulate production of antibodies that stop infections at a similar point. In 2004, West Nile virus, which is a mosquito-born...

Malfunctioning bone marrow cells sabotage nerve cells in diabetes

Secrets of the deep may hold key to life on other planets

...ed a natural environment research council grant to design and build seafloor fossilisation experiments to investigate this fundamental process. "We've already found a number of fossils, but don't know how they came to be there," said Dr Little. "Until we know more it's very difficult to interpret the fossil...
