Genomics Technique Accelerate Detection of Foodborne Bacterial Outbreaks

Diagnostic testing for foodborne pathogens relies on culture-based techniques that are not rapid enough for real-time disease surveillance and do not give a quantitative picture of pathogen abundance or the response of the natural microbiome. More...

Real-Time PCR Of Oropharyngeal Swabs Diagnoses Pneumonia in Adults

A lack of sensitive tests and difficulties obtaining representative samples contribute to the challenge in identifying etiology in pneumonia. Upper respiratory tract swabs can be easily collected and analyzed with real-time polymerase chain reaction (rtPCR). More...

Unique Assay Improves Cancer Diagnosis for Leukemia Patients

A new CE-IVD-marked assay for calreticulin (CALR) mutations, run on a well-established RT-PCR platform, aids in establishing the diagnosis of myeloproliferative neoplasms (MPN) in line with the latest WHO recommendations and clinical guidelines. More...

Blood Test Could Predict Best Treatment for Lung Cancer

A blood test could predict how well small-cell lung cancer (SCLC) patients will respond to treatment. In most patients with SCLC, a metastatic, aggressive disease, the condition is initially chemosensitive, but then relapses with acquired chemoresistance. More...

Rare Genetic Variations Linked to Schizophrenia

Genetic variations that increase schizophrenia risk are rare, making it difficult to study their role and to overcome this. Recently, the genomes of more than 41,000 people have been analyzed in the largest study of its kind to date. More...

Genetic Testing Identifies High-Risk Subtype of Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL) is less common in adults than in children, but adults are far less likely to survive. Adults make up about 40% of the estimated 6,590 new cases of ALL identified annually in the USA. More...

A, p15 expression in a benign intradermal nevus and B, antibody control C, co-immunofluorescence of p15 and Melan-A in a representative intradermal benign nevus. D, nevus melanocytes express p15, whereas non- nevus melanocytes (white arrows) are p15-negative (Photo courtesy of University of Pennsylvania).

Specific Gene Expression Differentiates Moles from Melanoma

Most melanomas are driven by mutations that spur out-of-control cell replication, while nevi which are moles composed of non-cancerous cells at the skin surface, that harbor the same mutations do not grow wildly. More...
