Nanopore Method Detects Single Influenza Virus at Single Particle Level

A team of Japanese researchers has introduced a novel sensor concept capable of discriminating various types of influenza virus in a label-free fashion by their distinct particle properties. More...

Highly Multiplexed Broad Pathogen Assay Detects Infectious Diseases

Identifying the causative agent in an acute febrile illness can be challenging diagnostically, especially when organisms in a particular region have overlapping clinical presentation or when that pathogen’s presence is unexpected. More...

Acute Myeloid Leukemia Regulatory Networks Identified

Adult acute myeloid leukemia (AML) is a type of cancer in which the bone marrow makes abnormal myeloblasts (a type of white blood cell), red blood cells, or platelets. AML is a heterogeneous disease caused by a variety of alterations in transcription factors, epigenetic regulators and signaling molecules. More...

Pregnancy-Related Immune Changes Revealed by Placenta Sequencing

A team of scientists has used single-cell RNA sequencing to map expression profiles in the placenta, focusing on the decidua tissue that forms from the lining of the uterus and placental trophoblast tissue from the fetus that interacts with maternal cells. More...

Image: The ability to detect cell-free circulating tumor DNA in blood provides the opportunity to develop non-invasive tests to measure tumor burden and detect molecular signatures in tumors that are associated with resistance to therapy (Photo courtesy of Huntsman Cancer Institute).

Sensitive Tumor Detection Uses Cell-Free DNA Methylomes

A combination of "liquid biopsy," epigenetic alterations and machine learning has been used to develop a blood test to detect and classify cancer at its earliest stages. The method holds promise of being able to find cancer earlier when it is more easily treated and long before symptoms ever appear. More...

Biomarker Found for Prostate Cancer Treatment Response

Prostate cancer is one of the most common cancers in males and has one of the highest five-year survival rate when diagnosed in the localized stage. When diagnosed in the advanced stage or when a localized tumor relapses after the initial local treatment, the usual procedure is to fight it using male hormone (androgen) deprivation therapy. More...

Recognized Cause of Pediatric Mitochondrial Disease Found

Leigh syndrome is a frequent, heterogeneous pediatric presentation of mitochondrial oxidative phosphorylation (OXPHOS) disease, manifesting with psychomotor retardation and necrotizing lesions in brain deep gray matter. More...
