Molecular Differences Discovered Among Ovarian Cancer Subgroups

Ovarian cancer is a highly diverse disease with a high rate of overall mortality. High-grade serous ovarian cancer (HGSC) is the most common and aggressive type of epithelial ovarian cancer, exhibiting high levels of tumor heterogeneity and variable clinical outcomes. More...

Urea Dissociation Tests Reduces SARS-CoV-2 IgM False-Positives

At present, the diagnosis of COVID-19 is mainly based on epidemiological history inquiry, laboratory testing, and chest radiology examination. Among these examinations, the detection of nucleic acid from SARS-CoV-2 is the direct evidence for COVID-19 diagnosis. More...

Human NK Cells Identified by Single-Cell RNA Sequencing

Natural killer (NK) cells are cytotoxic lymphocytes that are crucial for viral defense as well as detecting and killing cancer cells. This cell type is therefore of great interest for cancer immunotherapy. More...

Biomarker Panel Evaluated for Primary Hyperoxaluria Patients

Primary hyperoxaluria (PH) is a group of autosomal recessive disorders characterized by recurrent urinary stones and nephrocalcinosis. Roughly half of PH patients present with advanced chronic kidney disease (CKD) at the time of diagnosis. More...

Functional Comparison of Different Tubes for Isolating Mononuclear Cells

Profiling of immune cells with single-cell technologies is a key component of both basic science studies, evaluation of therapeutics in clinical trials, and clinical care. Cryopreserved human peripheral blood mononuclear cells (PBMCs) are a commonly used sample type for a variety of immunological assays. More...

Missing BAP1 Gene Associated with Immunosuppressive Molecules in Uveal Melanoma

Uveal melanoma is a cancer (melanoma) of the eye involving the iris, ciliary body, or choroid (collectively referred to as the uvea). Tumors arise from the pigment cells (melanocytes) that reside within the uvea and give color to the eye. More...

Commercial Kits Evaluated for Mediterranean Visceral Leishmaniasis

Human visceral leishmaniasis (VL) is a neglected disease endemic in the Mediterranean region, caused by Leishmania infantum. Accurate VL diagnosis is critical for rapid and correct patient management. Dogs are the main reservoir of L. infantum parasites that are transmitted to humans by the bite of infected phlebotomine sand flies. More...
