1. Hereditary hemochromatosis beyond hyperferritinemia: Clinical and laboratory investigation of the patient’s profile submitted to phlebotomy in two reference centers in southern Brazil
Abstract Hereditary Hemochromatosis is a disorder characterized by iron deposition in several organs and hyperferritinemia. The most studied variants are linked to the HFE gene. In Brazil, surveys that characterize this population are scarce, with no sampling in the state of Rio Grande do Sul. Our objective is to carry out a data collection focusing on the p

2. HFE hemochromatosis: an overview about therapeutic recommendations
Abstract Hemochromatosis is currently characterized by the iron overload caused by hepcidin deficiency. Large advances in the knowledge on the hemochromatosis pathophysiology have occurred due to a better understanding of the protein of the iron metabolism, the genetic basis of hemochromatosis and of other iron overload diseases or conditions which can lead

3. Effects of Incubator Carbon Dioxide and Oxygen Levels, and Egg Weight on Broilers’ Hatchability of Fertile Eggs
ABSTRACT This study investigated the effects of incubator carbon dioxide (CO2) and oxygen (O2) levels, and egg weight (EW) on embryo mortality (EM) and hatchability of fertile eggs (HFE). A total of 1920 hatching eggs were obtained from a middle-aged (41 weeks) ROSS 308 broiler breeder flock. The eggs were classified according to EW as heavy (69.63 ± 0.09 g

4. Hepcidin is a useful biomarker to evaluate hyperferritinemia associated with metabolic syndrome
Abstract: Investigation of hyperferritinemia in metabolic syndrome patients represents a diagnostic challenge, but it is essential for the identification of individuals with iron overload. Hepcidin negatively regulates iron absorption and release. An increase in hepcidin occurs when iron levels are sufficient or in inflammatory states, conditions often assoc

5. Effects of Protein in Diet and Sex Ratio on Egg Production, Egg and Hatching Chick Weight, Fertility, Hatchability and Embryonal Mortality in Pheasants (Phasianus Colchicus)
ABSTRACT This study was performed to investigate the effects of crude protein (CP) in diet and sex ratio on egg production, egg and hatching chick weight and hatchability traits in pheasants (Phasianus Colchicus). In this study, the treatment groups were constructed as 15% CP-5:1; 15% CP-7:1; 18% CP-5:1; 18% CP-7:1 for CP and sex (male:female) ratio respecti

6. Prevalência das mutações C282Y e H63D no gene HFEem pacientes de São Paulo e do Sul do Brasil
RESUMO A hemocromatose hereditária (HH) é uma desordem autossômica recessiva provocada por mutações no gene HFE e caracterizada pelo risco de uma sobrecarga de ferro. As mutações mais conhecidas associadas à HH são a C282Ye a H63D. Este estudo teve como objetivo determinar a frequência das mutações no sul do Brasil e em São Paulo. Ele utilizou a

7. Ancestral association between HLA and HFE H63D and C282Y gene mutations from northwest Colombia
A significant association between HFE gene mutations and the HLA-A*03-B*07 and HLA-A*29-B*44 haplotypes has been reported in the Spanish population. It has been proposed that these mutations are probably connected with Celtic and North African ancestry, respectively. We aimed to find the possible ancestral association between HLA alleles and haplotypes assoc

8. Mutations in the HFE gene and sporadic amyotrophic lateral sclerosis risk: a meta-analysis of observational studies
Iron homeostasis dysregulation has been regarded as an important mechanism in neurodegenerative diseases. The H63D and C282Y polymorphisms in theHFE gene may be involved in the development of sporadic amyotrophic lateral sclerosis (ALS) through the disruption of iron homeostasis. However, studies investigating the relationship between ALS and these two polym

9. Fatores precipitantes na porfiria cutanea tardia no Brasil com enfase nas mutacoes do gene (HFE) da hemocromatose. Estudo de 60 casos
FUNDAMENTOS: A porfiria cutânea tardia é a forma mais comum das porfirias e caracteriza-se pela diminuição da atividade da enzima uroporfirinogênio descarboxilase. Há vários relatos da associação das mutações do gene HFE da hemocromatose hereditária com porfiria cutânea tardia no mundo, mas até hoje apenas um estudo foi realizado no Brasil.

10. HFE MUTATIONS AND IRON OVERLOAD IN PATIENTS WITH ALCOHOLIC LIVER DISEASE
ContextoA doença hepática alcoólica (DHA) está geralmente associada à sobrecarga de ferro, que pode contribuir para a sua patogênese, através do aumento do estresse oxidativo e dano celular. As descrições existentes na literatura sobre a associação entre mutações HFE e a gravidade da DHA nem sempre são concordantes.ObjetivosComparar a prevalên

11. Porfiria cutânea tardia com mutações do gene da hemocromatose C282Y e H63D e análise retrospectiva do perfil de ferro em relação ao tratamento: estudo de 60 casos / Porphyria cutanea tarda with hemochromatosis gene mutations C282Y and H63D and retrospective analysis of the iron profile in relation to treatment: study of 60 cases
Background: Porphyria cutanea tarda (PCT) is the most common form of porphyria and is characterized by the decreased activity of the uroporphyrinogen decarboxylase enzyme. Several reports associated HFE gene mutations of hereditary hemochromatosis with PCT worldwide, although up to date only one study has been conducted in Brazil. Objective: Study the associ

12. Efeito do polimorfismo do gene HFE sobre a resposta viral sustentada em portadores de hepatite crônica C com ferritina sérica elevada
CONTEXTO: Níveis séricos anormais de ferritina são encontrados em aproximadamente 20%-30% dos pacientes com hepatite crônica C e estão associadas a uma baixa taxa de resposta à terapia com interferon. OBJETIVO: Avaliar a associação entre a presença de mutações do gene HFE e a taxa de resposta virológica sustentada ao interferon em pacientes porta
