Endothelial Cytotoxicity of Drug‐Doped Polypyrrole Coatings on Biodegradable Iron for Stent Applications

Advanced Materials Interfaces, EarlyView.
Electrochemically deposited polypyrrole coatings doped with salicylate and dexamethasone are tested on iron substrates. Their safety for biological use is confirmed in vitro with human endothelial cells. Abstract Conducting polymers, such as polypyrrole (PPy), are promising coatings for biodegradable vascular implants due to their electrical ...

Erythrocytes and Vascular Function: Oxygen and Nitric Oxide

Frontiers in Physiology, 2018
Erythrocytes regulate vascular function through the modulation of oxygen delivery and the scavenging and generation of nitric oxide (NO). First, hemoglobin inside the red blood cell binds oxygen in the lungs and delivers it to tissues throughout the body

Ceftriaxone-induced hemolysis

Indian Journal of Pharmacology, 2013
Immune hemolytic anemia is a rare adverse effect of ceftriaxone, a third-generation cephalosporin, which is a commonly used antibiotic. We describe a 60-years-old lady, a case of community-acquired pneumonia, who developed severe hemolysis after the first dose of ceftriaxone. Her hemoglobin dropped from 9.6 g /dl to 5.5 g /dl.

7-Keto-Cholesterol and Cholestan-3beta, 5alpha, 6beta-Triol Induce Eryptosis through Distinct Pathways Leading to NADPH Oxidase and Nitric Oxide Synthase Activation [PDF]

, 2019
BACKGROUND/AIMS: We showed that patho-physiological concentrations of either 7-keto-cholesterol (7-KC), or cholestane-3beta, 5alpha, 6beta-triol (TRIOL) caused the eryptotic death of human red blood cells (RBC), strictly dependent on the early production

Characterization of Renal Injury and Inflammation in an Experimental Model of Intravascular Hemolysis

Frontiers in Immunology, 2018
Intravascular erythrocyte destruction, accompanied by the release of pro-oxidative and pro-inflammatory components hemoglobin and heme, is a common event in the pathogenesis of numerous diseases with heterogeneous etiology and clinical features.

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, EarlyView.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.

Sublytic Terminal Complement Components Induce Eryptosis in Autoimmune Haemolytic Anaemia Related to IgM Autoantibodies [PDF]

, 2019
BACKGROUND/AIMS: Eryptosis, the suicidal death of red blood cells (RBCs), is characterized by phosphatidylserine (PS) exposure at the cell surface. It can be catalysed by a variety of abnormal conditions and diseases.

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

Advanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.

Evaluation of the red cell hemolysis in packed red cells during processing and storage

Asian Journal of Transfusion Science, 2011
Introduction : Storage of red cells causes a progressive increase in hemolysis. In spite of the use of additive solutions for storage and filters for leucoreduction, some amount of hemolysis is still inevitable.

A Degradable Device for Sustainable Capillary Blood Sampling

Advanced Materials Technologies, EarlyView.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...
