A complex signaling network involving protein kinase CK2 is required for hepatitis C virus core protein-mediated modulation of the iron-regulatory hepcidin gene expression
(2014)Hepatitis C virus (HCV) infection is associated with hepatic iron overload and elevated serum iron that correlate to poor antiviral responses. Hepcidin (HAMP), a 25-aa cysteine-rich liver-specific peptide, controls iron ... -
Does hepcidin affect erythropoiesis in hemodialysis patients?
(2006)Introduction: Prohepcidin is the precursor of hepcidin, a liver-derived peptide involved in iron metabolism by blocking its intestinal absorption and its release by the reticuloendothelial system. Iron overload and ... -
Effectors of Pregorexia and Emesis among Pregnant Women: A Pilot Study
(2022)During pregnancy, women tend to improve their lifestyle habits and refine their dietary intake. Quite often, however, these dietary improvements take an unhealthy turn, with orthorexia nervosa (ON) practices being apparent. ... -
Ferroportin in monocytes of hemodialysis patients and its associations with hepcidin, inflammation, markers of iron status and resistance to erythropoietin
(2014)Disturbed iron homeostasis contributes to resistance to recombinant human erythropoietin (rHuEpo) in hemodialysis (HD) patients. Increased hepcidin, which downregulates the iron exporter ferroportin, has been incriminated. ... -
Fibroblast Growth Factor 23 (FGF23) and Klotho Protein in Beta-Thalassemia
(2020)Derangements in phosphate and calcium homeostasis are common in patients with beta-thalassemia. Fibroblast growth factor 23 (FGF23) is among the main hormones regulating phosphate levels, while several studies underline ... -
Hair Loss After Laparoscopic Sleeve Gastrectomy
(2018)Aim: The aim of this study was to evaluate the prevalence of hair loss after laparoscopic sleeve gastrectomy (LSG). The effects of variables on the likelihood that patients developed hair loss were also examined. Material ... -
Iron status markers are only transiently affected by a football game
(2015)We examined the temporal variation of iron’s status markers during a 60 h period following a football game. Thirty-four male football players were randomly assigned to a control group (CG, N = 14, participated only in ... -
Iron Supplementation Effects on Redox Status following Aseptic Skeletal Muscle Trauma in Adults and Children
(2017)Exercise-induced skeletal muscle microtrauma is characterized by loss of muscle cell integrity, marked aseptic inflammatory response, and oxidative stress. We examined if iron supplementation would alter redox status after ... -
Iron-embedded nitrogen doped carbon frameworks as robust catalyst for oxygen reduction reaction in microbial fuel cells
(2017)A kind of 3D Fe-embedded N doped carbon framework catalyst is successfully developed and tested in the present work as a robust cathode catalyst for microbial fuel cells (MFCs). Due to the well-arranged mesopores, the high ... -
Management of iron deficiency in chronic heart failure: Practical considerations for clinical use and future directions
(2019)Heart Failure (HF) is a global pandemic with rapidly increasing prevalence. In an attempt to maintain patients well being, the therapeutic interest has expanded to the vicious cycles that confer to HF mortality and morbidity ... -
Novel Fe7S8/C nanocomposites with accelerating iron cycle for enhanced heterogeneous electro-Fenton degradation of dyes
(2022)Fe3+/Fe2+ interconversion is one of the key factors for heterogeneous electro-Fenton degradation of organic pollutants. In this study, MIL-101Fe-derived carbon wrapping Fe7S8 nanocomposite (Fe7S8/C-1-600) exhibits outstanding ... -
Numerical investigation of the contribution of metallic dowels to the stability of multi-drum columns
(2022)Remnants of Greek Temples are found all over the Mediterranean, surviving in most cases in the form of free-standing columns. In many cases the drums are placed on top of each other without any connection, whereas in some ... -
Oral sucrosomial iron improves exercise capacity and quality of life in heart failure with reduced ejection fraction and iron deficiency: a non-randomized, open-label, proof-of-concept study
(2021)Aims: Oral sucrosomial iron (SI) combines enhanced bioavailability and tolerance compared to conventional oral iron along with similar efficacy compared to intravenous iron in several conditions associated with iron ... -
Oxygen-dependent secretion of a bioactive hepcidin-GFP chimera
(2013)Hepcidin, a hepatic hormone, regulates serum iron levels by controlling both intestinal iron absorption and iron release from macrophages. Although transcription of hepcidin is controlled by diverse stimuli, it remains ... -
Role of microbial diversity for sustainable pyrite oxidation control in acid and metalliferous drainage prevention
(2020)Acid and metalliferous drainage (AMD) remains a challenging issue for the mining sector. AMD management strategies have attempted to shift from treatment of acid leachates post-generation to more sustainable at-source ... -
Serum copper and ferroportin in monocytes of hemodialysis patients are both decreased but unassociated
(2014)Disturbed iron homeostasis contributes to resistance to recombinant human erythropoietin (rHuEpo) in hemodialysis (HD) patients. Although increased hepcidin, which downregulates the iron exporter ferroportin, had been ... -
Transferrin receptor-1 and 2 expression in chronic lymphocytic leukemia
(2006)Transferrin receptor (TfR)-1 and 2 mRNA and CD71 (TfR1) expression was analyzed in 118 CLL patients. Ninety-five out of 109 analyzed cases expressed CD71, mostly at a high level; 60% of CD71 (+) cases were IGH-mutated. All ... -
Validation of a new t2∗ algorithm and its uncertainty value for cardiac and liver iron load determination from MRI magnitude images
