Abstract

This study sought to determine the value of portal venography with 64-slice MDCT in the evaluation of compensatory circulation resulting from decompensated posthepatitic cirrhosis (PHC), and in the clarification of its anatomic distribution. Thirty-six patients with clinically confirmed compensatory circulations resulting from PHC were enrolled in this study. They underwent thoracicoabdominal triphasic enhancement CT scans with 64-slice MDCT. The data of the portal venous phase acquired were used for obtaining CT-MIP (maximum intensity projection) images of portosystematic collaterals such as gastric fundic and esophageal varices, paraumbilical veins, spleno-renal shunts, and their inflowing and outflowing vessels. On CT-MIP portography, gastric fundic varices were shown in 35 cases (97%) and esophageal varices in 30 cases (83%). The left gastric vein was the common inflowing vessel of the varices in 34 cases (94%); it was mainly originated from splenic vein in 24 cases (67%). With regard to the outflowing vessels, they were commonly azygos vein in 30 cases (83%). As for paraumbilical veins in 7 cases (19%), the inflowing vessel was the left branch of portal vein, and the outflowing vesse was the superficial epigastric vein. Ca...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.
