High-sensitivity troponin test reduces risk of future heart attack

A blood test that measures the presence of heart-specific proteins called troponins is used by emergency clinics to diagnose myocardial infarction in patients with chest pain. For the past few years a newer laboratory method has been used at most hospitals in Sweden that is ten times more sensitive than the conventional troponin test. The […]

Pap test fluids used in gene-based screening test for two Gyn cancers

Cervical fluid samples gathered during routine Papanicolaou (Pap) tests are the basis of a new screening test for endometrial and ovarian cancers developed by researchers at the Johns Hopkins Kimmel Cancer Center. PapSEEK detects mutations in DNA that have been identified for specific cancers sooner. Earlier detection of cancer could lead to earlier treatment and […]

EKF procalcitonin assay validated for Beckman AU chemistry analysers

EKF Diagnostics announces that its Stanbio Chemistry Procalcitonin (PCT) LiquiColor® assay has been FDA cleared and validated for use on Beckman AU 480, 680 and 5800 clinical chemistry analysers.  EKF is pleased to confirm the immediate availability of a user-defined application (UDA) for running this 10-minute test for bacterial infection and sepsis on these Beckman […]

New methods for genetics analyses and diagnosis of inflammatory bowel disease

The two most common types of inflammatory bowel diseases are ulcerous colitis and Crohn’s disease. These are diagnosed by camera inside the gut, and by investigating small samples of the gut (biopsies). The diagnosis is often difficult, and if the wrong diagnosis is made, there may be severe consequences for the patients, because the treatments […]

Medical researchers find protein that marks difference between cancer and non-cancer cells

A discovery sheds light on how cancerous cells differ from healthy ones, and could lead to the development of new strategies for therapeutic intervention for difficult-to-treat cancers in the future. An international team of investigators found a “stop sign”—a modified protein researchers named a PIP-stop—inside cells that are overused by cancerous cells that effectively prevents […]

Researchers advance technique to detect ovarian cancer

Researchers at Rice University and the University of Texas MD Anderson Cancer Center have refined and, for the first time, run in vivo tests of a method that may allow nanotube-based probes to locate specific tumours in the body. Their ability to pinpoint tumours with sub-millimetre accuracy could eventually improve early detection and treatment of […]

Researchers take a step closer to developing a DNA test for liver cancer

A group of researchers from Mayo Clinic and Exact Sciences Corporation have completed a phase II study comparing a set of DNA markers to alpha fetoprotein as a method to test for liver cancer. “We currently test for liver cancer using ultrasound and a blood protein marker called alpha fetoprotein,” says John Kisiel, M.D., a […]

Genetic variants linked to type 2 diabetes identified in Chinese populations

Researchers investigated genomes from diverse Chinese populations to identify new and known genetic variants that contribute to a person’s blood sugar level and risk of Type 2 diabetes. Karen Mohlke at the University of North Carolina at Chapel Hill, Wei Huang at the Chinese National Human Genome Center and Shanghai Industrial Technology Institute, and their […]

Cancer’s gene-determined “immune landscape” dictates progression of prostate tumours

The field of immunotherapy – the harnessing of patients’ own immune systems to fend off cancer – is revolutionizing cancer treatment today. However, clinical trials often show marked improvements in only small subsets of patients, suggesting that as-yet unidentified variations among tumours result in distinct paths of disease progression and response to therapy. Now, researchers […]

Study provides more clarity on the genetic causes of children’s food allergies

What role do genes play in egg, milk, and nut allergies? A study, led by the Max Delbrück Center for Molecular Medicine (MDC) and Charité – Universitätsmedizin Berlin, has found five genetic risk loci that point to the importance of skin and mucous membrane barriers and the immune system in the development of food allergies.
