Outcomes of Endovascular Treatment for Salvaging Failed Hemodialysis Arteriovenous Fistula - Role of Balloon Angioplasty as Initial Therapy.

Background: This study aims to evaluate the technical and clinical outcomes of endovascular treatment for failed native hemodialysis fistulas, mainly the role of balloon angioplasty in salvaging thrombosed and stenosed arteriovenous fistulas.

Materials And Methods: This retrospective study was done on 23 patients who had presented with non-functioning dialysis fistulas. The mean age of the patients was 58.

Comparative secretome metabolic dysregulation by six engineered dietary nanoparticles (EDNs) on the simulated gut microbiota.

The potential use of engineered dietary nanoparticles (EDNs) in diet has been increasing and poses a risk of exposure. The effect of EDNs on gut bacterial metabolism remains largely unknown. In this study, liquid chromatography-mass spectrometry (LC-MS) based metabolomics was used to reveal significantly altered metabolites and metabolic pathways in the secretome of simulated gut microbiome exposed to six different types of EDNs (Chitosan, cellulose nanocrystals (CNC), cellulose nanofibrils (CNF) and polylactic-co-glycolic acid (PLGA); two inorganic EDNs including TiO and SiO) at two dietary doses.

Roadmap for Drug Product Development and Manufacturing of Biologics.

Therapeutic biology encompasses different modalities, and their manufacturing processes may be vastly different. However, there are many similarities that run across the different modalities during the drug product (DP) development process and manufacturing. Similarities include the need for Quality Target Product Profile (QTTP), analytical development, formulation development, container/closure studies, drug product process development, manufacturing and technical requirements set out by numerous regulatory documents such as the FDA, EMA, and ICH for pharmaceuticals for human use and other country specific requirements.

Chitosan nanofibrous scaffold with graded and controlled release of ciprofloxacin and BMP-2 nanoparticles for the conception of bone regeneration.

The repair of bone defects using grafts is commonly employed in clinical practice. However, the risk of infection poses a significant concern. Tissue engineering scaffolds with antibacterial functionalities offer a better approach for bone tissue repair.

Clinical Trial Comparing the Efficacy and Safety of Regional Citrate Anticoagulation Versus Heparin in CRRT.

Introduction: Heparin continues to be the most common modality of anticoagulation in CRRT. The increased risk of hemorrhagic complications associated with its use led to the emergence of regional citrate anticoagulation (RCA) as an alternative. However, the perceived complexities associated with its use and the risk of metabolic derangements have prevented it from being adopted on a larger scale.
