Abstract

Infarct size measured by microscopic method is consistently larger than that measured macroscopically, indicating that certain areas of infarction are missed when observed macroscopically. Existence of a good correlation between the two methods, however, suggests that macroscopic estimation of infarct size would be enough for initial screening of the interventions designed for salvation of ischemic myocardium, as it is an easy method. An additional advantage of this method is that it can be utilized to measure infarct size as early as 72 h after production of infarction. Comparison of weight and volume method of macroscopic estimation of infarct size has shown that they do not give significantly different results. Weight method being less cumbersome and less time-consuming, may be adopted for initial screening of cardioprotective agents.

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.
