Abstract

The aim of the present study was to assess the in-stent restenosis and occlusion of coronary artery stents by multislice computed tomography (MSCT) compared with conventional coronary angiography in patients with atypical chest pain and not practicable/non-conclusive stress test. Between December 2004 and March 2006, 81 patients were scheduled and of these 72 (65 men, mean age 61 years) with 90 stents underwent MSCT angiography using a 16-slice scanner, Toshiba Aquilion 16, 8-12 months after stent placement. Of the 90 stents, 71 (79%) could be assessed and 19 (21%) were excluded because the image quality at the stent level was incompatible with diagnostic assessment. This results in sensitivity, specificity, and positive and negative predictive values for all assessable stents in the identification of occlusion and/or in-stent restenosis of 82, 96, 87, and 94%, respectively. When the 19 uninterpretable stents were included in the analysis, the diagnostic accuracy of MSCT in detecting in-stent restenosis and occlusion resulted in a sensitivity of 82%, specificity of 71%, positive predictive value of 40%, and negative predictive value of 94%. The results of the study suggest that MSCT angiography is a useful method for evaluating...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.
