Abstract

The purpose of this study is to better define arteriographic selection criteria for living related liver transplantation (LRLT) based on literature review, technical and theoretical considerations, and correlation of patterns of variation in hepatic artery anatomy with recipient and donor outcomes. Visceral angiograms of 92 consecutive living related liver transplant donors were retrospectively reviewed by two radiologists and one transplant surgeon. Arterial configurations were categorized. Recipient and donor outcomes were determined by a review of transplant surgery and radiology records. Anomalous hepatic artery anatomy was identified in 67% of potential donors. A left hepatic artery (LHA) with a diameter of less than 2 mm was identified in 1%, and with a diameter of 2-3 mm, in 5%. A dual LHA supply to the left lateral segment was identified in 11%. Two subtypes were defined. Bifurcation of the LHA into branches entering segment II and segment III less than 1 cm from the LHA origin was present in 8%. A replaced LHA from the left gastric artery (17%) and complex, aberrant branching of the LHA (4%) were identified. Vital LHA supply to tissue other than the left lateral segment was present in 21%, including the cystic artery a...Continue Reading

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.
