Multivariate Approaches Boosting Lithium-Mediated Ammonia Electrosynthesis in Different Electrolytes.

Ammonia electrosynthesis through the lithium-mediated approach has recently reached promising results towards high activity and selectivity in aprotic media, reaching high Faradaic efficiency (FE) values and NH production rates. To fasten the comprehension and optimization of the complex lithium-mediated nitrogen reduction system, for the first time a multivariate approach is proposed as a powerful tool to reduce the number of experiments in comparison with the classical one-factor-at-a-time approach. Doehlert design and surface response methodology are employed to optimize the electrolyte composition for a batch autoclaved cell.

Value of NT-ProBNP level and echocardiographic parameters in ST-segment elevation myocardial infarction treated by primary angioplasty: relationships between these variables and their usefulness as predictors of ventricular remodeling.

Introduction And Objectives: To assess the value of N-terminal fragment of brain natriuretic peptide (NT-proBNP) measurement and echocardiography for predicting ventricular remodeling after myocardial infarction and to investigate relationships between the NT-proBNP level and echocardiographic parameters at discharge and in the medium term.

Methods: The study involved 159 patients with myocardial infarction treated by primary coronary angioplasty. The NT-proBNP level was measured on admission, at discharge and after 6 months.

Sirolimus-eluting stents compared with standard stents in the treatment of patients with primary angioplasty.

Background: Sirolimus-eluting stents have been shown to decrease restenosis and reintervention as compared with standard stents. We evaluated the use of sirolimus-eluting stents in primary percutaneous coronary intervention for acute myocardial infarction with ST-segment elevation.

Methods: We randomly assigned 120 patients to compare sirolimus-eluting stents with uncoated stents in primary percutaneous coronary intervention for acute myocardial infarction with ST-segment elevation.

[Percutaneous treatment of bifurcation lesions by crush T stenting: immediate and medium-term outcomes].

Introduction And Objectives: Percutaneous coronary intervention for coronary bifurcations is usually associated with a low success rate, a high rate of complications, and a more frequent need for target lesion revascularization. The aim of this prospective study was to evaluate immediate and medium-term clinical and angiographic outcomes after the application of crush T stenting.

Methods: This approach to bifurcation stenting follows the same steps as modified T stenting.
