The accuracy of magnetic resonance (MR) imaging was assessed for in vivo measurement of the ventricular end-systolic pressure-volume relation (ESPVR) and preload recruitable stroke work (PRSW). The conductance catheter was used as reference. In 10 pigs, ventricular volumes were measured with both methods under different loading conditions at two levels of contractility. Increased contractility resulted in a significant leftward shift of the ESPVR and PRSW for both methods. The magnitude of these shifts was on average similar for the two methods; MR imaging, 6.9 ml for ESPVR, 9.3 ml for PRSW; and the conductance catheter, 7.4 ml for ESPVR, 9.1 ml for PRSW. It was concluded that MR imaging may be used for in vivo analysis of pressure-volume relations, and that its sensitivity for detecting contractility changes is similar to that of the conductance catheter method.

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.

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.

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.
