Representative Tumor Sampling Method Lessens Molecular Analyses Bias

Over the past decade, clinical scientists have demonstrated the inability of an individual biopsy or formalin-fixed paraffin-embedded (FFPE) block to capture the genetic diversity of a solid tumor. More...

An Analytical Method to Monitor Dietary Fat Intake

An advanced analytical technique was used to determine unequivocally the composition of fats in the diets of pregnant women and female patients suspected of being deficient in certain dietary fats. More...

Germline Risk Variants Found in Prostate Cancer Patients

Studies done over the past five years or so have unearthed pathogenic germline variants in some 12% to 17% of men with prostate cancer, and such alterations can impact everything from the treatment options available to them, to the management strategies used for other members of the same family. More...

Non-Invasive Blood Assay Can Detect Early Colorectal Cancer

Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine). In general, colon cancer begins when healthy cells in the colon develop changes (mutations) in their DNA and as the cells accumulate, they form a tumor. More...

New Blood Test Can Determine When an Individual Was Exposed to a Pathogenic Microorganism

An international research team has developed a diagnostic blood test – initially for the recurring form of vivax malaria – that can determine when an individual was exposed to a pathogenic microorganism, including the coronavirus that causes COVID-19. More...

Rare Kidney Cancer Marked by Molecular Features

Renal medullary carcinoma is a rare cancer of the kidney that predominantly afflicts young people of African descent who carry the sickle cell trait, sickle cell disease, or other sickle hemoglobinopathies that can cause sickling of the red blood cells. More...

Higher Concentrations of COVID-19 Receptor Protein Found in Men’s Plasma

Results of a large-scale study revealed that plasma concentrations of angiotensin-converting enzyme 2 (ACE2) were higher in men than in women, but use of neither an ACE inhibitor nor an angiotensin receptor blocker (ARB) was associated with higher plasma ACE2 concentrations. More...
