BD (Becton, Dickinson and Company), a leading global medical technology company, today announced the CE-IVDD certification of the BD COR™ System in Europe. The high throughput solution for infectious disease diagnostics sets a new standard in automation for molecular testing in core laboratories and other large centralized laboratories.

New research demonstrating the clinical utility of Bio-Rad's Droplet Digital PCR (ddPCR) powered liquid biopsy will be presented this week during the 2019 American Association for Cancer Research (AACR) Annual Meeting in Atlanta, March 29-April 3. Many of the studies rely on the sensitivity, speed, and cost-effectiveness of ddPCR technology to measure blood-based tumor biomarkers in a reproducible way.
Immune checkpoint inhibitors, such as the anti-PD-1 antibody pembrolizumab, have become important tools for managing non-small-cell lung cancer (NSCLC). Assessing the level of programmed death ligand 1 (PD-L1) expressed by a tumor can help clinicians determine how the patient should be treated. A report in The Journal of Molecular Diagnostics describes a novel and rapid approach for quantifying PD-L1 expression levels in tumors that requires only small amounts of tissue that can be collected using minimally-invasive bronchoscopy techniques.
A highly sensitive blood test that detects minute traces of cancer-specific DNA has been shown to accurately determine whether patients with HPV-related oropharyngeal squamous cell carcinoma (OPSCC) are free from cancer following radiation therapy. Findings will be presented today at the 60th Annual Meeting of the American Society for Radiation Oncology (ASTRO).
Yale Cancer Center (YCC) scientists have filled in a key gap in understanding the unusual route by which the Human papillomavirus (HPV) infects cells. Their findings, published online today in the journal Cell, may eventually help to broaden the scope of defenses against HPV and provide valuable clues for delivering drugs into cells.
HPV is a family of killers. Although there are effective vaccines against these viruses, they still cause about 5% of cancer deaths worldwide, including more than 250,000 women who die of cervical cancer each year.
When it comes to diagnosing a condition in which the plasma cells that normally make antibodies to protect us instead become cancerous, it may be better to look at the urine as well as the serum of our blood for answers, pathologists say.
The condition is monoclonal gammopathy, in which immune cells called plasma cells start making just one immunoglobulin, or antibody, instead of their usual vast array. The result can be the cancer multiple myeloma.
Human papillomavirus (HPV) genotyping assays are becoming increasingly attractive for use in mass screening, as they offer a possibility to integrate HPV screening with HPV vaccine monitoring, thereby generating a synergy between the two main modes of cervical cancer prevention. The Genomica CLART HPV2 assay is a semi-automated PCR-based microarray assay detecting 35 high-risk and low-risk HPV genotypes. However, few reports have described this assay in cervical screening.
Existing microscopy-based methods of detecting apoptosis, such as TUNEL (terminal deoxynucleotidyl transferase dUTP nick-end labeling), have limited quantitative capabilities due to insufficient signal-to-noise ratios. Researchers at the National Cancer Institute and National Cancer Institute-Frederick have addressed this issue via development of a highly specific apoptosis assay designed for immunofluorescence microscopy analysis of fixed core needle biopsy specimens.
A Phase I clinical trial testing the safety of vaccines that might have the potential to prevent HIV infection will begin this month at four sites in the United States, marking the latest step in a three-decade quest at UMass Medical School to harness the power of DNA vaccines in addressing a major global health threat. The study, which is the result of research by Shan Lu, MD, PhD, professor of medicine and biochemistry & molecular pharmacology, will also monitor the vaccine's ability to create an immune response against HIV.
Physicians now have a more dependable, less expensive tool to help detect bladder cancer earlier.
Researchers at The University of Texas M. D. Anderson Cancer Center found that a simple test that can be administered and read in the doctor's office was three times more effective than a conventional laboratory test for detecting bladder cancer.
