Developing new biomarkers for liver cancer with RNA splicing techniques

Researchers at Cold Spring Harbor Laboratory (CSHL), led by Professor Adrian Krainer, have developed a method for identifying splicing-based biomarkers for hepatocellular carcinoma (HCC). They have published their findings in journal Genome Research. Different versions, or isoforms, of messenger RNAs generated by the human AFMID gene, are represented, showing their relative prevalence in cancerous (top) …

Peripheral vision reaction time assessment to diagnose mild traumatic brain injury patients

A new test using peripheral vision reaction time could lead to earlier diagnosis and more effective treatment of mild traumatic brain injury, often referred to as a concussion, according to Peter J. Bergold, PhD, professor of physiology and pharmacology at SUNY Downstate Medical Center and corresponding author of a study published by the Journal of Neurotrauma. While …

Research categorizes depression in to 4 subtypes based on fMRI scans

Patients with depression can be categorized into four unique subtypes defined by distinct patterns of abnormal connectivity in the brain, according to new research from Weill Cornell Medicine. In a collaborative study published in Nature Medicine, Dr. Conor Liston, an assistant professor of neuroscience in the Feil Family Brain and Mind Institute and an assistant …

Fluselenamyl in conjuction with positron emission tomography (PET) scans shown effective in diagnosing early Alzheimer’s disease pathology

Researchers at Washington University School of Medicine in St. Louis have developed a chemical compound, named Fluselenamyl, that detects amyloid clumps better than current FDA-approved compounds. If a radioactive atom is incorporated into the compound, its location in a living brain can be monitored using positron emission tomography (PET) scans. The compound, described in a paper …
