Abstract

A series of 45 adults with severe valvular aortic stenosis underwent echocardiographic examination before surgery. The echocardiographic indices of the severity of the stenosis were reviewed: In M mode: aortic valve opening was only clearly defined and quantifiable in 22 out of 45 cases. In these 22 cases, the separation of the valves was variable in 9 cases; the stenosis was underestimated in 2 cases both of which were unsuspected bicuspid valves; the stenosis were overestimated in 1 case leading to an erroneous diagnosis. In 2D: aortic valve opening was easier to detect than in M mode; it was quantifiable in 16 out of 21 patients (80 p. 100). The subcostal view was particularly valuable in patients with chronic pulmonary disease or with barrel-shaped chests. The 2D examination however, suffers from the same limitations as M mode: variability in the values of aortic valve opening in a third of cases and a general tendency to overestimate the severity of the stenosis. In two cases an erroneous diagnosis of severe stenosis was made in cases of simple aortic sclerosis either because of the inability to visualise a mobile 3rd left anterior cusp in the long axis view or because of artefact due to paravalvular calcification.

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.
