Effects of Implementing a Heart Failure Order Set to Optimize Guideline-Directed Medical Therapy and Diuresis in Patients with Acute Heart Failure.

Utilization of guideline-directed medical therapy in patients hospitalized for acute heart failure is suboptimal during the hospitalization and after discharge. An inpatient heart failure order set may be a convenient and useful intervention to improve heart failure therapy in the inpatient setting. This is a retrospective study that assessed the use of an inpatient heart failure order set on pharmacologic therapy in patients hospitalized for acute heart failure from May to August 2022.

Modular synthesis of amphiphilic Janus glycodendrimers and their self-assembly into glycodendrimersomes and other complex architectures with bioactivity to biomedically relevant lectins.

The modular synthesis of 7 libraries containing 51 self-assembling amphiphilic Janus dendrimers with the monosaccharides D-mannose and D-galactose and the disaccharide D-lactose in their hydrophilic part is reported. These unprecedented sugar-containing dendrimers are named amphiphilic Janus glycodendrimers. Their self-assembly by simple injection of THF or ethanol solution into water or buffer and by hydration was analyzed by a combination of methods including dynamic light scattering, confocal microscopy, cryogenic transmission electron microscopy, Fourier transform analysis, and micropipet-aspiration experiments to assess mechanical properties.

Improved tumor targeting of polymer-based nanovesicles using polymer-lipid blends.

Block copolymer-based vesicles have recently garnered a great deal of interest as nanoplatforms for drug delivery and molecular imaging applications due to their unique structural properties. These nanovesicles have been shown to direct their cargo to disease sites either through enhanced permeability and retention or even more efficiently via active targeting. Here, we show that the efficacy of nanovesicle targeting can be significantly improved when prepared from polymer-lipid blends compared with block copolymer alone.

Quantitative analysis of three-dimensional fluid flow in rotating bioreactors for tissue engineering.

Tissue engineering has emerged as a viable alternative to the problem of organ and tissue shortage. Our laboratory has developed matrices for bone tissue engineering based on sintered spherical particles and, using bioreactor technology, has demonstrated the ability to produce highly mineralized matrices in vitro. In this study, porous microcapsule scaffolds were developed for bone tissue engineering in the high aspect ratio vessel rotating bioreactor.
