The collaboration was led by Erin Purcell, assistant professor of biomedical engineering at Michigan State University; Joseph W. Salatino, Purcell's graduate student researcher; Kip A. Ludwig, associate director of technology at Mayo Clinic; and Takashi Kozai, assistant professor of bioengineering at the University of Pittsburgh's Swanson School of Engineering. "Glial cells
Researchers with NIH's National Institute of Biomedical Imaging and Bioengineering (NIBIB) have devised an innovative biochemical formula of mineralized compounds that interacts in the bloodstream to regulate blood sugar for days at a time. In a proof-of-concept study performed with mice, the researchers showed that the biochemically formulated patch of
Now, an international group of researchers including UIC professor of chemistry Petr Kral, have designed new anti-viral nanoparticles that bind to a range of viruses, including herpes simplex virus, human papillomavirus, respiratory syncytial virus and Dengue and Lentiviruses. Unlike other broad-spectrum antivirals, which simply prevent viruses from infecting cells, the
In a study led by Dipanjan Pan, an Illinois professor of bioengineering, researchers designed nanoparticles that specifically bind to a protein that marks the surface of breast cancer stem cells. Encapsulated in the particles is the drug niclosamide -- a drug commonly prescribed around the world to treat tapeworm infections,
Cancer is caused by changes in the human genome. Mutations in oncogenes and in tumor suppressor genes accumulate unrecognized over time and lead to uncontrolled cell proliferation eventually. In 50% of all human tumors the tumor suppressor gene TP53 is no longer functional being the most frequently mutated cancer gene.
Specifically, the team used neutron crystallography to study the location of hydrogen atoms in aspartate aminotransferase, or AAT, an enzyme vital to the metabolism of certain amino acids. "We visualized the first neutron structure of a vitamin B6 enzyme that belongs to a large protein family with hundreds of members that exist
Out of this realization has come a debate: how such proteins spend their time when floating in the cell. Since they're not folded into their precise shapes, do they contract into balls, or remain expanded, like a rope? Different methods have yielded different results. Scattering using X-rays suggested they remained
Researchers at the University of Washington developed a device smaller than a toaster that can detect the level of hemoglobin in whole blood samples using optical absorbance. The work is published this week in AIP Advances, from AIP Publishing. Hemoglobin is a protein found in red blood cells that transports oxygen throughout
