Abstract

Despite its proven superiority compared to conventional echocardiographic techniques, three-dimensional (3D) echocardiography has not gained widespread acceptance in clinical medicine for the quantification of left ventricular volumes, function and mass. This is mainly due to the large, time-consuming process of data analysis. We sought to validate a new method that enables the accurate quantification of the left ventricle in a clinically acceptable short period of time. Left ventricular volumes, ejection fraction and mass were determined in 44 patients using 3D echocardiography. The 3D echocardiographic data sets were analysed: (i) using the conventional 'summation of slices' algorithm (slice thickness 5 and 10mm), which is based on the analysis of the 3D reconstructed left ventricle in short-axis cross-sections; and (ii) using the new method which is based on the analysis of the 3D reconstructed left ventricle in long-axis images. In each patient measurements were repeated using 3, 6, 7, 8, 9, 12 and 15 long-axis images. For all volumetric measurements there was a continuous reduction of measurement variability using increasing numbers of long-axis images. The use of more than nine long-axis images for volumes, and eight long...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.
