Detecting Cancer as DNA Changes Could Enhance Diagnosis

DNA methylation is an epigenetic modification involving the addition of a methyl group to DNA, which is heavily involved in gene expression and regulation, thereby critical to the progression of diseases such as cancer. More...

Cytology Test for Pre-Cancer Diagnosis Receives FDA Approval

A cytology test, which is the only clinically validated cyclin-dependent kinase inhibitor 2A (p16) biomarker test that, when used in conjunction with hematoxylin & eosin (H&E) staining, helps pathologists determine which women should receive treatment for cervical pre-cancer. More...

Bacterial Panel Detects Stool Pathogens from Swabs

Repeated bouts of diarrhea and persistent diarrheal disease disrupt intestinal function and absorption, making diarrheal disease a leading cause of malnutrition in children less than 5 years of age. Importantly, diarrheal disease is both treatable when correctly diagnosed and preventable via proper infection control measures. More...

New sPCR Technology Runs on Standard Devices

Synergistic PCR (sPCR), a new method of DNA analysis developed for use on a new high-speed assay device, can also be carried out on widely available laboratory real-time PCR (qPCR) instruments and does not require calibration. More...

Gene-Based Blood Tests Identify More Skin Cancers

Genetic testing of tumor and blood fluid samples from people with and without one of the most aggressive forms of skin cancer has shown that two new blood tests can reliably detect previously unidentifiable forms of the disease. More...

Routine Donor Screening Revealed Acute Usutu Virus

Usutu virus (USUV) an Old World flavivirus included in the Japanese encephalitis virus (JEV) antigenic complex is transmitted by mosquitoes to birds that act as the main amplifying hosts, while humans are considered incidental or dead-end hosts. More...
