Plasma Virome of Brazilians with Unexplained Symptoms of Infection

 Deep sequencing of nucleic acids in clinical samples now allows the identification of any known infectious agents, resulting in improved diagnostic capabilities. Blood from healthy people with high exposure to viral infections has also been analyzed using metagenomics. More...

Increased Membrane Glycoprotein Level Predicts Lung Cancer Metastasis

 A protein found in extracellular vesicles (Evs) shed by lung cancer cells was found to be an effective, relatively noninvasive biomarker for the early detection of lung cancer metastasis and could shape the direction of therapeutic decisions. More...

EGFR Mutation Assay Cartridges Evaluated

 Lung cancer remains the leading cause of cancer deaths. The management of lung cancer has been aided by the better understanding of molecular mechanisms involved in its initiation and progression and increased usage of molecular testing. More...

Combination of Genetic Signatures Identifies Ultra High Risk Multiple Myelomas

 Combining two panels of genetic biomarkers enabled cancer researchers to identify multiple myeloma patients at “ultra high risk” of progression of the disease and probable lack of response to lenalidomide, the primary drug used to treat it. More...

SARS-CoV-2 Detected in Multiple Sample Types

 An epidemic of respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in China and has spread to other countries. Real-time reverse transcriptase–polymerase chain reaction (rRT-PCR) of nasopharyngeal swabs typically has been used to confirm the clinical diagnosis. More...

T-cell Monitoring to Predict Risk of Kidney Transplant Failure

 A recently published paper discussed the potential application of CD8+ memory T-cell monitoring to improve risk prediction for kidney transplant failure. More...

NGS Identifies Genomic Characteristics of Pediatric Leukemia

 Pediatric leukemias have a diverse genomic landscape associated with complex structural variants, including gene fusions, insertions and deletions, and single nucleotide variants. Routine karyotype and fluorescence in situ hybridization (FISH) techniques lack sensitivity for smaller genomic alternations. More...
