Current-Tunneling Measurements Analyze Single DNA Molecules

A team of Japanese genomics researchers has devised a method for cancer diagnosis, which is based on the analysis of single molecules of DNA without the need for chemical modification or amplification. More...

Variant CJD Diagnosed by Protein Misfolding Amplification

Variant Creutzfeldt-Jakob disease (vCJD) is a neurodegenerative infectious disease caused by transmission of a cattle prion disease (bovine spongiform encephalopathy) to humans. Most vCJD cases have occurred in the United Kingdom, where an estimated 1 in 2,000 persons is potentially asymptomatically infected. More...

Recurrent Rearrangements Identified in Soft Tissue Tumors

A new genomic and transcriptomic analysis of rare, soft tissue tumors that develop in infants has detected recurrent specific gene rearrangements that may render them responsive to targeted treatment. More...

Image: Neuromyelitis optica (NMO) is an autoimmune disease and a potentially fatal disease in which the immune system attacks cells in the optic nerve and spinal cord. Aquaporin-4–immunoglobulin G (AQP4-IgG) is the specific biomarker for NMO spectrum disorders and most accurately diagnosed using a cell-based blood test (Photo courtesy of Mayo Clinic Laboratories).

DNA Code Unraveled for Rare Neurologic Disease

Neuromyelitis optica (NMO) is a potentially fatal disease in which the immune system attacks cells in the optic nerve and spinal cord, leaving some patients blind and/or paralyzed. More...

Measurement of Two Biomarkers Predicts Diabetes Risk

Results presented in a recently published study indicated that it is possible to predict likelihood of developing diabetes by measuring the levels of two biomarkers in a single blood sample. More...

UTIs Diagnosed with Genetic Analysis of Cell-Free DNA

Genetic analysis of cell-free DNA (cfDNA) in urine samples reveals valuable information, which enables comprehensive monitoring of host and pathogen dynamics in bacterial and viral urinary tract infections. More...

Gene Signatures and Biomarkers Predict RA Onset

Rheumatoid arthritis is characterized by joint inflammation leading to destruction of bone and cartilage. Since structural joint damage is irreversible, early recognition and treatment is a key focus in an effort to halt the progression of the disease. More...
