Iron-carbohydrate complexes treating iron anaemia: Understanding the nano-structure and interactions with proteins through orthogonal characterisation

Antonia Neels, Marianne Liebi, Tiberiu Totu

Intravenous (IV) iron-carbohydrate complexes are widely used nanoparticles (NPs) to treat iron deficiency anaemia, often associated with medical conditions such as chronic kidney disease, heart failure and various inflammatory conditions. Even though a ple ...

Iron status influences non-alcoholic fatty liver disease in obesity through the gut microbiome

Xavier Fernandez-Real Girona

Background: The gut microbiome and iron status are known to play a role in the pathophysiology of nonalcoholic fatty liver disease (NAFLD), although their complex interaction remains unclear. Results: Here, we applied an integrative systems medicine approa ...

Factors influencing safety and efficacy of intravenous iron-carbohydrate nanomedicines: From production to clinical practice

Heinrich Hofmann

Iron deficiency is an important subclinical disease affecting over one billion people worldwide. A growing body of clinical records supports the use of intravenous iron-carbohydrate complexes for patients where iron replenishment is necessary and oral iron ...

Low Fe(II) Concentrations Catalyze the Dissolution of Various Fe(III) (hydr)oxide Minerals in the Presence of Diverse Ligands and over a Broad pH Range

Janet Gordon Hering

Dissolution of Fe(III) (hydr)oxide minerals by siderophores (i.e., Fe-specific, biogenic ligands) is an important step in Fe acquisition in environments where Fe availability is low. The observed coexudation of reductants and ligands has raised the questio ...

Iron phosphate nanoparticles for food fortification: Biological effects in rats and human cell lines

Christian Ludwig

Nanotechnology offers new opportunities for providing health benefits in foods. Food fortification with iron phosphate nanoparticles (FePO4 NPs) is a promising new approach to reducing iron deficiency because FePO4 NPs combine high bioavailability with sup ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, Michel Prudent, Manon Sandra Bardyn

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

Iron regulatory proteins and their role in controlling iron metabolism

Cellular iron homeostasis is regulated by post-transcriptional feedback mechanisms, which control the expression of proteins involved in iron uptake, release and storage. Two cytoplasmic proteins with mRNA-binding properties, iron regulatory proteins 1 and ...

Iron Pincer Complexes as Catalysts and Intermediates in Alkyl Aryl Kumada Coupling Reactions

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Gerald Bauer

Iron-catalyzed alkylaryl Kumada coupling has developed into an efficient synthetic method, yet its mechanism remains vague. Here, we apply a bis(oxazolinylphenyl)amido pincer ligand (Bopa) to stabilize the catalytically active Fe center, resulting in isola ...

The In-Vivo Use of Superparamagnetic Iron Oxide Nanoparticles to Detect Inflammation Elicits a Cytokine Response but Does Not Aggravate Experimental Arthritis

Heinrich Hofmann, Lionel André Maurizi

Background Superparamagnetic Iron Oxide Nanoparticles (SPION) are used in diagnostic imaging of a variety of different diseases. For such in-vivo application, an additional coating with a polymer, for example polyvinyl alcohol (PVA), is needed to stabilize ...

Large scale inkjet-printing of carbon nanotubes electrodes for antioxidant assays in blood bags

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar, Niels Erik Lion, Michel Prudent

Herein, we present the large scale fabrication of carbon nanotubes (CNT) electrodes supported on flexible polymeric sheets by subsequent multilayer inkjet printing of a silver layer for electrical connection, CNT layers as active electrode material and an ...

A fast and reproducible method to quantify magnetic nanoparticle biodistribution

Heinrich Hofmann, Lionel André Maurizi, Usawadee Sakulkhu

The quantification of nanoparticles, particularly superparamagnetic iron oxide nanoparticles (SPIONs), both in vitro and in vivo has become highly important in recent years. Some methods, such as induced coupled plasma (ICP) spectroscopy and UV-visible che ...

Cell viability assessment by flow cytometry using yeast as cell model

Philippe Renaud, Niccolo Piacentini, Nina Buffi

This paper reports the new combination of cell sorting and counting capabilities on a single device. Most state-of-the-art devices combining these technologies use optical techniques requiring complicated experimental setups and labeled samples. The use of ...

Intestinal ferritin H is required for an accurate control of iron absorption

Lukas Kühn

To maintain appropriate body iron levels, iron absorption by the proximal duodenum is thought to be controlled by hepcidin, a polypeptide secreted by hepatocytes in response to high serum iron. Hepcidin limits basolateral iron efflux from the duodenal epit ...

Analysis of mice with conditional ferritin H deletion

Iron is a transitional metal required by virtually all organisms as a dietary micromineral, indispensable for cellular survival and proliferation. The management of iron absorption and distribution in the organism and inside the cell must be tightly regula ...

Conditional deletion of ferritin H in mice induces loss of iron storage and liver damage

Friedrich Beermann, Lukas Kühn

Ferritin plays a central role in iron metabolism by acting both as iron storage and detoxifying protein. We have generated a ferritin H allele with loxP sites and studied the conditional ferritin H deletion in adult mice. Ten days after Mx-Cre induced dele ...

Differential translational regulation of IRE-containing mRNAs in Drosophila melanogaster by endogenous IRP and a constitutive human IRP1 mutant

Lukas Kühn

Insects, like vertebrates, express iron regulatory proteins (IRPs) that may regulate proteins in cellular iron storage and energy metabolism. Two mRNAs, an unspliced form of ferritin H mRNA and succinate dehydrogenase subunit b (SDHb) mRNA, are known to co ...

Delivery of erythropoietin by encapsulated myoblasts in a genetic model of severe anemia

Patrick Aebischer, Bernard Schneider, Nicole Déglon

BACKGROUND: Existing animal models of anemia inadequately reflect the hematocrit usually present in chronic renal failure (CRF) patients and do not permit long-term treatment studies. The transgenic mouse strain 134.3LC (Epo-TAg(H)) displays a severe chron ...
