Abstract

Treatment of significant coronary artery disease with primary percutaneous coronary intervention (PCI) seems better than angioplasty balloon; because the incidence of restenosis is lower in this method, however, a serious complication of PCI is stent thrombosis which would lead to repeated myocardial infarction (MI) and increase the mortality and morbidity. One of the frequent medications which is used to prevent from stent thrombosis is clopidogrel, but, stent thrombosis was seen in many of the patients despite given the conventional dosage of this drug. This study aimed to evaluate the effect of doubling the maintenance dose of clopidogrel to prevent from early stent thrombosis, MI and mortality rate. This was a clinical trial study which was done in Shahid Chamran Hospital in winter 2010 in Isfahan, Iran. A total of 400 patients with PCI were prospectively followed-up for 30 days. All the patients were randomly allocated into two groups. The control group received a maintenance dose of 75 mg clopidogrel while the case group received 150 mg clopidogrel after the initial dosage of 600 mg for 30 days after the PCI. The incidence of primary outcome such as total mortality was recorded during the study. Early stent thrombosis was...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.
