Effects of Limiting the Number of Different Cross-Sections Used in Statically Loaded Truss Sizing and Shape Optimization.

This research aims to show the effects of adding cardinality constraints to limit the number of different cross-sections used in simultaneous sizing and shape optimization of truss structures. The optimal solutions for sizing and shape optimized trusses result in a generally high, and impractical, number of different cross-sections being used. This paper presents the influence of constraining the number of different cross-sections used on the optimal results to bring the scientific results closer to the applicable results.

Oligonucleotide-Blocked Streptavidin for Biotinylation Analysis.

Binding between streptavidin, or its homologues, to biotin is one of the most widely exploited biological interactions in the biomedical sciences. Controlling the extent of biotinylation is important for meeting the requirements of the intended design and to preserve the native function of the biotin recipient. Within the protein world, a"trial-and-error" optimization approach toward biotinylation reaction conditions is often necessary due to widely varying properties of proteins.

Prevention, treatment and outcomes of left ventricular assist device driveline infections. A single Center experience.

Introduction: While the survival rates for patients with end-stage heart failure have dramatically improved with newer generations of left ventricular assist devices, LVAD-specific infections are important cause of morbidity, mortality, and hospital readmissions in these patients.

Methods: We performed a retrospective analysis of all driveline infections in patients who had undergone LVAD implantation at a single cardiosurgical center. Between June 2013 and March 2017, 51 patients underwent implantation of LVAD.

Improvement of Glycemic Control in Insulin-Dependent Diabetics with Depression by Concomitant Treatment with Antidepressants.

BACKGROUND It is still disputable whether negative effects of comorbid depression in diabetics can be diminished by successful treatment of depression. The primary aim of this study was to assess whether addition of antidepressants to existing insulin treatment would further improve glycemic control in these patients. A secondary objective was to assess whether such treatment impairs their lipid and inflammatory status.

Quantitation of brinzolamide in dried blood spots by a novel LC-QTOF-MS/MS method.

In the current study, a rapid and sensitive LC-QTOF-MS/MS method for the determination of brinzolamide in dried blood spots (DBS) was developed and validated. This novel sample collection, storage and transfer technique was suitable for analyzing a drug with high distribution into red blood cells and negligible plasma levels. The method included an isocratic mobile phase consisting of methanol and 10mM ammonium formate (90:10, v/v) and detection in positive electrospray mode (ESI+).
