Various Manifestations of 5-Fluorouracil Cardiotoxicity: A Multicenter Case Series and Review of Literature.

5-Fluorouracil is a key element to the treatment of colon cancer. But it is also one of the most cardiotoxic chemotherapies, and the management of those that experience cardiotoxicity can be challenging. We present three cases of 5-FU cardiac toxicity that manifested as myocardial infarction, cardiogenic shock, and ventricular fibrillation.

Temporal trends, outcomes, and predictors of mortality after pericardiocentesis in the United States.

Background: Data regarding the temporal trends, outcomes, and predictors of in-hospital mortality after pericardiocentesis are limited.

Methods: The National Inpatient Sample database was used to extract hospitalizations of patients who underwent pericardiocentesis from January 2007 to September 2015. We examined the rates of in-hospital mortality, its predictors, and the temporal trends of pericardiocentesis utilization in the United States during the study period.

Two Arabidopsis loci encode novel eukaryotic initiation factor 4E isoforms that are functionally distinct from the conserved plant eukaryotic initiation factor 4E.

Canonical translation initiation in eukaryotes begins with the Eukaryotic Initiation Factor 4F (eIF4F) complex, made up of eIF4E, which recognizes the 7-methylguanosine cap of messenger RNA, and eIF4G, which serves as a scaffold to recruit other translation initiation factors that ultimately assemble the 80S ribosome. Many eukaryotes have secondary EIF4E genes with divergent properties. The model plant Arabidopsis (Arabidopsis thaliana) encodes two such genes in tandem loci on chromosome 1, EIF4E1B (At1g29550) and EIF4E1C (At1g29590).
