Abstract

From April, 1983 to March, 1993, 63 patients (pts) underwent reoperations of valvular heart disease at Tokyo Medical and Dental University Hospital, of which 44 pts had undergone closed mitral commissurotomy (CMC), open aortic or mitral commissurotomy (OAC or OMC) or valvuloplasty, and 17 pts had undergone aortic or mitral valve replacement (AVR or MVR). Valve replacement was performed in 59 pts (mechanical valve replacement; 42 pts, porcine valve replacement; 12 pts), and 2 pts received OMC due to restenosis after CMC. Preoperative diagnosis included restenosis after CMC, OMC or valvuloplasty in 43 pts, bioprosthetic dysfunction after MVR in 10 pts, perivalvular leakage after AVR in 1 pt, valve detachment after AVR in 4 pts (Beçhet 3 pts, infective endocarditis 1 pts). Valve replacement or valvuloplasty was done for another valves in addition to the previously operated valve in 44 pts (72.1%), especially for tricuspid valve. Restenosis after CMC, occurred at 20.6 years after surgery, and restenosis after OMC and valvuloplasty at 13.1 years. Bioprosthetic dysfunction after MVR occurred at 8.5 years. Valve dysfunction of the mechanical valve was not observed. The early operative mortality after reoperations was 11.5% (7 pts) in ...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.
