LINKOPING, Sweden, Nov. 26, 2012 /PRNewswire-iReach/ -- According to the Chief CT Technologist of RAS, Shane Shepherd, "We performed side-by-side comparisons between Sapheneia's Clarity and the solution available from our original equipment manufacturer, (OEM), of our CT scanners. Our radiologists agreed Clarity(TM) performed as well as the OEM solution when comparing image quality at lower doses. Additionally, Sapheneia was able to provide us a custom solution to cater to the varying...

The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer. In a study published online this week in the Proceedings of the National Academy of Sciences, scientists at the Ludwig Institute for Cancer Research in Oxford discovered a critical molecular switch that regulates autophagy. They also studied the links between autophagy...

A Simon Fraser University graduate student's collaboration with her thesis supervisor on how a particular type of protein controls the growth of another protein could advance cancer research. Their findings have just been published in the online July 26 issue of Current Biology, a CellPress journal. Esther Verheyen, an SFU professor of molecular biology and biochemistry, has helped her Master's of Science student Joanna Chen uncover how Hipk can be manipulated to stop Yorkie from...

The human body does a great job of generating new cells to replace dead ones but it is not perfect. Cells need to communicate with or signal to each other to decide when to generate new cells. Communication or signaling errors in cells lead to uncontrolled cell growth and are the basis of many cancers. At The University of Texas Health Science Center at Houston (UTHealth) Medical School, scientists have made a key discovery in cell signaling that is relevant to the fight against melanoma...

SAN DIEGO, April 30, 2012 /PRNewswire/ -- Trovagene, Inc. (Pink Sheets: TROV.PK), a developer of trans-renal molecular diagnostics, announced today that the Company has successfully completed the analytical development of digital PCR assays for the detection of the most prevalent K-RAS mutations, which are, according to recent estimates, observed in more than 90% of pancreatic cancers(1-3), and in 23% of all solid tumors(4). The Company intends to establish and validate the performance of...

Researchers trace influence via mouse model that allows oncogene to be turned on and off A genetic mutation that drives the initiation of pancreatic cancer also manipulates metabolic pathways to support tumor growth and progression, scientists report in the journal Cell. This newly discovered role for the Kras oncogene opens up a new category of potential targets for thwarting the influential mutation, which has proved difficult to attack directly, said study co-lead author Haoqiang...

Testing patients with non-small cell lung cancer for both mutations and amplifications of the KRAS gene prior to therapy may help to predict response to treatment with antifolates, according to the updated results of a preclinical study presented at the AACR Annual Meeting 2012, held here March 31 - April 4. Patients, especially those with lung cancer, who have KRAS gene mutations have a worse prognosis and do not respond well to targeted therapies, according to Sarah Bacus, Ph.D.,...

Better understanding of cancer-promoting pathway may lead to new strategy for treatment-resistant tumors Researchers from the Massachusetts General Hospital (MGH) Cancer Center have identified a new potential strategy for treating colon tumors driven by mutations in the KRAS gene, which usually resist both conventional and targeted treatments. In a paper appearing in the Feb. 17 issue of Cell, the team reports that targeting a later step in the pathway leading from KRAS activation to tumor...
