A bacterial genome reveals new targets to combat infectious disease

...understanding the details of this relationship may help identify new strategies for controlling diseases caused by filarial nematodes. In a new study published in the freely-available online journal PLoS Biology, Barton Slatko and colleagues present the complete DNA sequence of the Wolbachia pipientis str...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

... the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows. Researchers at the University of Michigan Comprehensive Cancer Center developed the assessment, which they call a functional diffusion...

Gene variations explain drug dose required to control seizures

...r conditions in which gene-based diagnostics might help determine the optimum dosage of particular therapies for particular patients, Goldstein said. "For most drugs we know a lot about how and where they act in the body," Goldstein said. "The current results support the idea that known drug targets, tra...

Purdue proves concept of using nano-materials for drug discovery

...te of Indiana to promote high-tech research and to help commercialize innovations. The vessels discussed in the research paper are cylindrical cavities that are open at the top and sealed at the bottom with a material called alumina, which contains numerous pores measured in nanometers, or billionths of ...

Researchers identify target for cancer drugs

...when mTOR and rictor bind and form a complex, they help activate Akt by adding a phosphate group to a sequence of its amino acids (a process called "phosphorylation"). This process occurs not only in human cells but in other organisms such as the fruit fly. Finding this complex conserved in species as di...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...in plant root nodules. Furthermore, these proteins help to maintain free-oxygen concentrations in nodules at levels low enough to avoid damage of oxygen-sensitive nitrogenase, the bacterial enzyme complex responsible for symbiotic nitrogen fixation. Thus, plant hemoglobins fulfill roles analogous to those...
