Abstract

Immediate effect of PTCA and CABG for unstable angina then followed-up for PTCA and CABG several years are analyzed in 112 patients selected out of 204 unstable angina patients hospitalized from 1990 to 1991. Fifty three patients, aged 25-68 (mean 51) were assigned to PTCA, fifty nine aged 33-69 (mean 53) were subjected to CABG. Both groups comprised of 72% and 83% males respectively. Nine patients with de novo angina, forty with crescendo angina and four with prolonged stenocardia were assigned to PTCA. 28% of patients have had myocardial infarction. Nine patients with de novo angina and fifty with crescendo angina were assigned to CABG. 56% of them have had myocardial infarction. Left ventricular ejection fraction (LVEF) less than 40% was found in 8 (15%) PTCA patients and in 18 (31%) patients who underwent CABG. Full revascularization was achieved in 38 (73%) patients treated with PTCA and 46 (78%) CABG patients. In 9/17% patients only critical stenosis in multivessel disease was subjected to PTCA. Four cases of myocardial infarction underwent intervention and all of these patients died: one (2%) after PTCA, and three (5%) after CABG. Fifty two patients after PTCA and fifty six after CABG were followed for one to four (mean ...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.
