Abstract

Multislice computed tomography (CT) is widely used in analysing the native coronary arteries. The usefulness of 64 slice CT in patients with coronary artery bypass grafts (CABG) is analysed in the present study. Sixty-five patients (59 [92%] males and 6 [8%] females with the mean age of 59 ± 9.1 years) underwent 64 slice CT and a total of 186 bypass grafts (62 arterial and 124 venous grafts) were analysed using 64 slice CT. Bypass grafts and native vessels with the diameter of >1.5 mm were evaluated for the presence of significant stenosis of >70%. In all patients invasive coronary angiogram was done. On the whole 43 venous grafts and 3 arterial grafts were found to be occluded. Majority of the grafts were occluded at the ostium. It was observed that the 64 slice CT was 90% sensitive and 96% specific for the evaluation of bypass grafts. It had 95% positive predictive value and 93% negative predictive value for predicting the luminal narrowing of grafts. For the assessment of arterial graft, it was 80% sensitive, 100% specific with a positive predictive value of 100% and negative predictive value of 93%. For the evaluation of venous grafts, the sensitivity, specificity, positive, and negative predictive value were 94%, 94%, 93%,...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.
