Metabolomic Analytical Approach Identifies Multiple Neonatal Errors of Metabolism Disorders

A recent paper demonstrated that an untargeted metabolomics analytical approach could identify many more neonatal disorders caused by inborn errors of metabolism (IEM) than could be found by traditional methods. More...

Targeted Locus Amplification Validated for Lymphoma

Structural variation (SV) in the genome is a recurring hallmark of cancer. Translocations (genomic rearrangements between chromosomes) in particular are found as recurrent drivers in many types of hematolymphoid malignancies. More...

Protein Biomarker Helps Diagnose Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC), characterized by dense desmoplastic stroma laid down by pancreatic stellate cells (PSC), has no reliable diagnostic biomarkers for timely detection. More...

Rotavirus Co-Infection with Diarrheagenic Pathogens Detected by Different Methods

Diarrhea is the second most common cause of childhood mortality worldwide, with Group A Rotavirus (RVA) recognized as a leading diarrheagenic agent, causing 38% of acute diarrhea among children aged five and below worldwide. More...

Portable, PCR-Based Assay Developed for Rapid, Multiplexed DNA Detection

The detection of specific DNA sequences is central to precision medicine, from pathogen identification to the risk assessment of human genetic diseases to disease prognosis. While technologies exist for DNA detection, they tend to be limited either in terms of multiplexing, turnaround times, quantification accuracy, or specificity for single-nucleotide differences.

Genotyping Helps Avoid Needless Bone Marrow Biopsies in African-Americans

Bone marrow biopsies may be used unnecessarily in some African American individuals who are genetically predisposed to having relatively low white blood cell counts. More...

A Novel Nanowell Array Sensor for POC Measurement of Stress Hormones

Researchers have constructed a microchip "nanosensor" to measure stress hormones such as cortisol in a dedicated nanowell array, which does not require molecular labels or washing steps. More...
