Antithrombotic and Antimicrobial Potential of S -Nitroso-1-Adamantanethiol-Impregnated Extracorporeal Circuit.

This study presents the utilization of a novel, highly lipophilic nitric oxide (NO) donor molecule, S -nitroso-1-adamantanethiol (SNAT), for developing an NO-emitting polymer surface aimed at preventing thrombus formation and bacterial infection in extracorporeal circuits (ECCs). S -nitroso-1-adamantanethiol, a tertiary nitrosothiol-bearing adamantane species, was synthesized, characterized, and used to impregnate polyvinyl chloride (PVC) tubing for subsequent in vivo evaluation. The impregnation process with SNAT preserved the original mechanical strength of the PVC.

Mechanistic analysis of the photolytic decomposition of solid-state S-nitroso-N-acetylpenicillamine.

S-Nitroso-N-acetylpenicillamine (SNAP) is among the most common nitric oxide (NO)-donor molecules and its solid-state photolytic decomposition has potential for inhaled nitric oxide (iNO) therapy. The photochemical NO release kinetics and mechanism were investigated by exposing solid-state SNAP to a narrow-band LED as a function of nominal wavelength and intensity of incident light. The photolytic efficiency, decomposition products, and the photolytic pathways of the SNAP were examined.

A Pumpless Pediatric Artificial Lung Maintains Function for 72 h Without Systemic Anticoagulation Using the Nitric Oxide Surface Anticoagulation System.

Background: Children with end-stage lung disease are commonly managed with extracorporeal life support (ECLS) as a bridge to lung transplantation. A pumpless artificial lung (MLung) is a portable alternative to ECLS and it allows for ambulation. Both ECLS and pumpless artificial lungs require systemic anticoagulation which is associated with hemorrhagic complications.

ULTRASOUND-GUIDED PERCUTANEOUS TREATMENT OF HEPATIC HYDATIDOSIS IN TWO RED-SHANKED DOUC LANGURS ().

Hydatid disease caused by is a major cause of morbidity and mortality for critically endangered captive langurs in northern Vietnam. The most common sites for hydatid cyst development are the liver and the lungs. Chemotherapy trials with albendazole alone or in combination with praziquantel in these langurs had varying results and in most cases were ineffective.

Controllable release of nitric oxide from an injectable alginate hydrogel.

Currently, the controlled release of nitric oxide (NO) plays a crucial role in various biomedical applications. However, injectable NO-releasing materials remain an underexplored research field to date. In this study, via the incorporation of S-nitroso-N-acetyl-penicillamine (SNAP) as an NO donor, a family of NO-releasing injectable hydrogels was synthesized through the in situ cross-linking between sodium alginate and calcium ion induced by D-(+)-gluconate δ-lactone as an initiator.
