Extracting information on virus-human interactions and on antiviral compounds based on automated analysis of large text collections.

The development of effective antivirals is of great importance due to the threat associated with the rapid spread of viral infections. The accumulation of data in scientific publications and in databases of biologically active compounds provides an opportunity to extract specific information about interactions between chemicals and their viral and host targets. This information can be used for elucidation of knowledge about potential antiviral activity of chemical compounds, their side effects and toxicities.

The effect of coronary revascularization treatment timing on mortality in patients with stable ischemic heart disease in British Columbia.

Background: Prior research has shown that patients with stable ischemic heart disease who undergo delayed coronary artery bypass graft (CABG) surgery face higher mortality rates than those who receive CABG within the time recommended by physicians. However, this research did not account for percutaneous coronary intervention (PCI), a widely available alternative to delayed CABG in many settings. We sought to establish whether there was a difference in mortality between timely PCI and delayed CABG.

The effect of treatment timing on repeat revascularization in patients with stable ischemic heart disease.

Objectives: In patients with stable ischemic heart disease, there is no evidence for the effect of revascularization treatment timing on the need for repeat procedures. We aimed to determine if repeat revascularizations differed among patients who received coronary artery bypass graft surgery after the time recommended by physicians compared with those who had timely percutaneous coronary intervention.

Methods: We identified 25,520 British Columbia residents 60 years or older who underwent first-time nonemergency revascularization for angiographically proven, stable left main or multivessel ischemic heart disease between January 1, 2001, and December 31, 2016.

Prediction of viral protease inhibitors using proteochemometrics approach.

Being widely accepted tools in computational drug search, the (Q)SAR methods have limitations related to data incompleteness. The proteochemometrics (PCM) approach expands the applicability area by using description for both protein and ligand structures. The PCM algorithms are urgently required for the development of new antiviral agents.

Lanthanide Contraction in F ( = Ce-Lu) and Its Chemical and Structural Consequences: Part 2: Specialized Empirical System of ( = Y, La, and 14 ) and F Ionic Radii for F Series.

A () () for = Y, La, , and F ( rare earth elements ()) was derived from the dependence of () on the () of (). LC decreased the radius of the cation with increasing Z. The structures of -F (LaF-NdF, "-SmF") of the LaF type, 11 -F ( = Sm-Lu), and -YF of the β-YF type were studied.
