Abstract

The Liver Imaging Reporting and Data System (LI-RADS) is a comprehensive system for standardizing the terminology, interpretation, reporting, and data collection of liver imaging. Over the past 10 years, LI-RADS has undergone a substantial expansion in scope, building on and refining its initial CT and MRI algorithm for hepatocellular carcinoma (HCC) diagnosis and developing three new algorithms: ultrasound (US) LI-RADS for HCC screening and surveillance, contrast-enhanced US (CEUS) LI-RADS for HCC diagnosis, and LI-RADS CT/MRI treatment response. As of 2018, LI-RADS and the American Association for the Study of Liver Diseases (AASLD) guidance share LR-5 (definitely HCC) criteria for the image-based diagnosis of HCC, and LI-RADS diagnostic criteria and management recommendations were integrated into the AALSD clinical practice guidance for HCC diagnosis, staging, and management. LI-RADS is updated in response to new knowledge, technology, and user feedback every 3-5 years. This article details the origins and growth of LI-RADS, reviews its current state, and articulates its short- and long-term objectives.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
