Morphology of sections through the fetal heart

International Journal of Cardiology

Abstract

Two human embryos, of 28 and 29 mm crown-rump length, were studied. One had been serially sectioned in the transverse plane, the other in the sagittal plane. With the help of a graphic reconstruction method two new sets of sectioning planes were constructed. One set started from the transverse plane, which was gradually angulated towards the frontal plane. The other set started from the sagittal plane, which, too, was angulated towards the frontal plane. These procedures were carried out at various levels in both cases. We produced a continuous series of sectioning planes of the young fetal heart, which together give a clear representation of spatial morphology. We believe that these images can be of help in the interpretation of fetal echocardiograms. The morphology of these young fetuses differs considerably from older stages in that the atrioventricular septum is not yet present. Full development of the tricuspid valve and the mitral valve can only later lead to the different septal attachments of the two valves.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
