Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

Advanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...

Coronary magnetic resonance imaging after routine implantation of bioresorbable vascular scaffolds allows non-invasive evaluation of vascular patency. [PDF]

, 2018
Evaluation of recurrent angina after percutaneous coronary interventions is challenging. Since bioresorbable vascular scaffolds (BVS) cause no artefacts in magnetic resonance imaging (MRI) due to their polylactate-based backbone, evaluation of vascular ...

Determinants of patency of arteriovenous fistula in hemodialysis patients

Saudi Journal of Kidney Diseases and Transplantation, 2018
The arteriovenous fistula (AVF) is the vascular access of the first choice for hemodialysis (HD). Studies on patency of AVF and its affecting factors reveal a high risk for access failure. The aim of this study was to assess the primary and secondary AVF

Patency and effectiveness of vascular access for hemodialysis patients: a descriptive study

Polish Journal of Cardio-Thoracic Surgery
Vascular access is one of the most important issues affecting the quality of life of patients who are dialysis-dependent.The aim of our study was to determine the infection rates of permanent catheters. We also evaluated the thrombosis, maturation time, and patency rates of arteriovenous fistulas based on their location in the arm in dialysis patients ...
