Urine-Based Liquid Biopsy Test Detects Urothelial Carcinoma

Urine cytology, which is widely used to screen for bladder cancer, has high specificity but lacks sensitivity, especially for low-grade cancers. Cystoscopy, while more accurate than cytology, is an invasive procedure with added costs and potential complications for the patient. More...

Analysis of Placental Cell Free DNA and RNA Predicts Gestational Complications

A recent paper revealed that circulating cell-free nucleic acids (DNA and RNA) shed from the placenta into the mother's blood during the first trimester of pregnancy could be used to predict potentially serious complications such as ischemic placental disease and gestational diabetes. More...

Exome Sequencing Identifies Genetic Loci Linked to the Fetal Syndrome Nonimmune Hydrops Fetalis

An exome sequencing technique was used to identify genetic loci linked to development of about 30% of cases of nonimmune hydrops fetalis (NIHF). More...

Mutations Disrupting Neuritogenesis Genes Confer Risk for Cerebral Palsy

Cerebral palsy (CP) is a group of permanent movement disorders that appear in early childhood. Signs and symptoms vary among people and over time. Often, symptoms include poor coordination, stiff muscles, weak muscles, and tremors. More...

Elevated Levels of Defective Mitochondrial DNA Predict Likelihood of Reproductive Success

A sperm biomarker has been found that may be able to supplement or replace the semen parameters that poorly predict reproductive success yet are the most prevalent diagnostic tool for male infertility. More...

Use of Dried Blood Samples Facilitates Tracking of COVID-19 Antibodies

A recent study confirmed that dried blood spot samples could be used as an alternative to venous blood for detecting antibodies to the SARS-CoV-2 virus (COVID-19). More...
