Heme-regulated eIF2alpha kinase (HRI) is essential for regulating globin translation in iron deficiency and in beta-thalassemia. We investigated the role of heme-regulated eIF2alpha kinase in hemoglobin and red blood cell production as well as in iron homeostasis in a mouse model of iron overload. We show that HRI deficiency does not significantly affect red cell parameters of hemochromatosis (...
In this article, we investigate the question of equivalent keys for two Multivariate Quadratic public key schemes HFE and C∗−− and improve over a previously known result, to appear at PKC 2005. Moreover, we show a new non-trivial extension of these results to the classes HFE, HFEv, HFEv-, and C∗−−, which are cryptographically stronger variants of the original HFE and C∗ / MIA schemes. In partic...
Mutations in the HFE (hemochromatosis) gene cause hereditary hemochromatosis, an iron overload disorder that is hallmarked by excessive accumulation of iron in parenchymal organs. The HFE mutation p.Cys282Tyr is pathologically most relevant and occurs in the Caucasian population with a carrier frequency of up to 1 in 8 in specific European regions. Despite this high prevalence, the mutation cau...
Our paper ‘A strategy for human factors/ergonomics: developing the discipline and profession’ (Dul et al. 2012) was intended to suggest directions for and to stimulate discussions in the human factors/ergonomics (HFE) community on the future of our field. We believe that discussing the future is an urgent endeavour, as – after decades of existence – in many parts of the world HFE is often under...
BACKGROUND Approximately one-half of Brazilian patients with hereditary hemochromatosis (HH) are neither homozygous for the C282Y mutation nor compound heterozygous for the H63D and C282Y mutations that are associated with HH in Caucasians. Other mutations have been described in the HFE gene as well as in genes involved in iron metabolism, such as transferrin receptor 2 (TfR2) and ferroportin 1...
BACKGROUND Gastric bypass surgery is a highly effective therapy for long-term weight loss in severely obese patients, but carries significant perioperative risks including infection, wound dehiscence, and leaks from staple breakdown. Iron status can affect immune function and wound healing, thus may influence peri-operative complications. Common mutations in the HFE gene, the gene responsible f...
BACKGROUND Pathological brain iron deposition has been implicated as a source of neurotoxic reactive oxygen species in Alzheimer (AD) and Parkinson diseases (PD). Iron metabolism is associated with the gene hemochromatosis (HFE Human genome nomenclature committee ID:4886), and mutations in HFE are a cause of the iron mismetabolism disease, hemochromatosis. Several reports have tested the associ...
BACKGROUND Hereditary hemochromatosis (HH) is a common autosomal recessive disorder in populations of European descent. It is characterized by a variable prevalence of mutations in the hemochromatosis gene (HFE) in different countries and a complex relationship between the HFE genotype and the HH phenotype. Genetic analysis has not been conducted in Croatian patients with iron overload. The aim...
Hereditary hemochromatosis is a disorder of iron metabolism characterized by increased iron intake and progressive storage and is related to mutations in the HFE gene. Interactions between thalassemia and hemochromatosis may further increase iron overload. The ethnic background of the Brazilian population is heterogeneous and studies analyzing the simultaneous presence of HFE and thalassemia-re...
