Structure of molecular machine that targets viral DNA for destruction determined

Posted: Published on August 9th, 2014

With a featured publication in the Aug. 7 issue of Science, Montana State University researchers have made a significant contribution to the understanding of a new field of DNA research, with the acronym CRISPR, that holds enormous promise for fighting infectious diseases and genetic disorders. The MSU-led research provides the first detailed blueprint of a multi-subunit "molecular machinery" that bacteria use to detect and destroy invading viruses. "We generally think of bacteria as making us sick, but rarely do we consider what happens when the bacteria themselves get sick. Viruses that infect bacteria are the most abundant biological agents on the planet, outnumbering their bacterial hosts 10 to 1," said Blake Wiedenheft, senior author of the paper and assistant professor in MSU's Department of Microbiology and Immunology. "Bacteria have evolved sophisticated immune systems to fend off viruses. We now have a precise molecular blueprint of a surveillance machine that is critical for viral defense," Wiedenheft said. These immune systems rely on a repetitive piece of DNA in the bacterial genome called a CRISPR. CRISPR is an acronym that stands for Clustered Regularly Interspaced Short Palindromic Repeats. These repetitive elements maintain a molecular memory of viral infection by inserting short segments … Continue reading →

St. Elizabeth’s Hospital cardiology department honored

Posted: Published on August 9th, 2014

BELLEVILLE The cardiology department at St. Elizabeth's Hospital has been awarded for excellence for the second consecutive year. On Friday, the Belleville hospital announced it has received the American College of Cardiology's NCDR ACTION Registry-GWTG Platinum Performance Achievement Award for 2014. St. Elizabeth's Hospital is one of only 256 hospitals nationwide to receive the honor. Bonnie Schnieder, director of Heart and Vascular Services at St. Elizabeth's Hospital, said this award reflects the hospital's ongoing commitment to patient care. "I believe more than anything, this shows the dedication to the quality that we provide," Schnieder. "We are doing a good job meeting all of the guidelines that the American College of Cardiology puts forward for us. We adhere to that by going above and beyond so patients have the best possible care." St. Elizabeth's Hospital cardio lab director Dr. Atul Shah said this award reveals the outstanding service by physicians and staff throughout the hospital. "Everybody is very closely involved and really interested in making sure that the proper care is given," Shah said. Shah is also manager of the Prairie Cardiovascular Consultants Ltd., a group of about 75 cardiologists serving patients from Springfield to Carbondale. About 10 of those cardiologists … Continue reading →

New Nano3 microscope will allow high-resolution look inside cells

Posted: Published on August 9th, 2014

PUBLIC RELEASE DATE: 8-Aug-2014 Contact: Tiffany Fox tfox@ucsd.edu 858-246-0353 University of California - San Diego The University of California, San Diego's Nanofabrication Cleanroom Facility (Nano3) is the first institution to obtain a novel FEI Scios dual-beam microscope, with an adaptation for use at cryogenic temperatures. The new microscope will enable research among a highly diverse user base, ranging from materials science to structural and molecular biology. As Nano3 Technical Director Bernd Fruhberger explains: "There is a tremendous interest in utilizing this instrument among faculty from multiple departments. The Departments of Nanoengineering, Materials and Aerospace Engineering, Electrical and Computer Engineering, Chemistry, Physics and Biology at UC San Diego all have projects in need of this tool, and have been actively involved in making the procurement of the tool a reality. "The instrument provides state-of-the-art capabilities for cross-sectioning, preparation of sections for Transmission Electron Microscopy and more," he adds, "but what truly differentiates it is the novel cryo-capability, which will make it possible for cell biologists to see the structures of biological cells in higher resolution to better understand how cells function at a molecular level. This could possibly pave the way for new treatments and drug discovery." Elizabeth Villa, a new … Continue reading →
