Cyclodextrin-Based Polymeric Materials Bound to Corona Protein for Theranostic Applications.

Cyclodextrins (CDs) are cyclic oligosaccharide structures that could be used for theranostic applications in personalized medicine. These compounds have been widely utilized not only for enhancing drug solubility, stability, and bioavailability but also for controlled and targeted delivery of small molecules. These compounds can be complexed with various biomolecules, such as peptides or proteins, via host-guest interactions.

Stabilization of Delphinidin in Complex with Sulfobutylether-β-Cyclodextrin Allows for Antinociception in Inflammatory Pain.

Delphinidin (DEL) is a plant-derived antioxidant with clinical potential to treat inflammatory pain but suffers from poor solubility and low bioavailability. The aim of the study was to develop a well-tolerated cyclodextrin (CD)-DEL complex with enhanced bioavailability and to investigate the mechanisms behind its antinociceptive effects in a preclinical model of inflammatory pain. CD-DEL was highly soluble and stable in aqueous solution, and was nontoxic.

Association of increased myocardial contractility and elevated end-diastolic wall tension with short-term myocardial ischemia: a pressure-volume analysis.

Objective: Critical myocardial oxygen imbalance as indicated by elevated interstitial lactate levels may occur in cases of rapidly elevated end-diastolic myocardial wall tension during elevated myocardial contractility in the intact myocardium. Simultaneous administration of beta-adrenergic receptor agonist and antagonist reliably allows for investigating the myocardial response.

Design: Experimental using an in vivo animal model.

How to distinguish between ischemic and nonischemic postsystolic thickening: a strain rate imaging study.

Ongoing myocardial thickening after aortic valve closure (postsystolic thickening = epsilonPST) is an established marker for the presence of segmental ischemia. However, epsilonPST may also be present in late activated segments and can be induced by pharmacological interventions or left ventricular pressure overload. The aim of this study was to determine if it is possible to distinguish between ischemic and nonischemic epsilonPST.

Determination of preload-recruitable stroke work and elastance by the relationship of arterial blood flow velocity to left ventricular area.

Objective: The authors investigated the feasibility of an online sampling and display of LV flow-area loops for the determination of LV elastance and preload-recruitable stroke work (PRSW). Automated LV area measurements by echocardiography may be combined with flow velocity measurements in the internal carotid artery to construct LV flow-area loops as estimates of the systolic pressure-volume relationship.

Setting: University hospital.
