1. Increased hepcidin expression in multibacillary leprosy
Iron is essential for all organisms and its availability can control the growth of microorganisms; therefore, we examined the role of iron metabolism in multibacillary (MB) leprosy, focusing on the involvement of hepcidin. Erythrograms, iron metabolism parameters, pro-inflammatory cytokines and urinary hepcidin levels were evaluated in patients with MB and m

2. Non-HFE hemochromatosis
Hereditary hemochromatosis (HH) is an autosomal recessive disorder classically related to HFE mutations. However, since 1996, it is known that HFE mutations explain about 80% of HH cases, with the remaining around 20% denominated non-HFE hemochromatosis. Nowadays, four main genes are implicated in the pathophysiology of clinical syndromes classified as non-H

3. Evolução de indicadores nutricionais de saúde infantil entre 2003 e 2007 em área urbana de Acrelândia, Acre / Evolution of nutritional indicators of child health between 2003 and 2007 in urban area of Acrelândia, Acre
Introduction: The nutritional picture of Brazilian infancy in recent decades is characterized by a downward trend in the prevalence of malnutrition and unchanged prevalence of anemia, especially iron deficiency anemia. However, regional inequalities persist, particularly in the North of the country. The early and inadequate introduction of foods has been con

4. Estudo in vitro sobre a interação celular e vias endocíticas de papilomavírus humano (HPV) em leucócitos do sangue periférico. / In vitro study on the interaction of human papillomavirus in cell from peripheral blood leukocytes.
Human papillomavirus (HPV) is the primary etiologic agent of anogenital and cervical cancer, caused mainly by the high-risk HPV16 and HPV18 viruses. Recent studies revealed that besides the sexual transmission of HPV, there are other forms of contagion. However, the difficulty in obtaining quantities of viable wild-type or mutant of HPV constitutes a limitin

5. Avaliação da expressão de hepcidina e produção de IL-6 por monócitos de indivíduos idosos / Evaluation of hepcidin expression and IL-6 production by monocytes in elderly
Anemia in elderly is associated with increased morbidity and mortality in this population. The causes of anemia in elderly can be divided into three groups: anemia of chronic diseases (ACD), anemia of nutrients deficiency, which include iron deficiency anemia (IDA) and unexplained anemias. Hepcidin is an important link between primary defense, inflammation a

6. Analysis of HFE and non-HFE gene mutations in Brazilian patients with hemochromatosis
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 transferr

7. Complementary feeding and nutritional status of 6-24-monthold children from Acrelândia, Acre, Westhern Brazilian Amazon / Alimentação complementar e estado nutricional de crianças menores de dois anos em Acrelândia, Acre, Amazônia Ocidental Brasileira
Objective: To investigate the nutritional status, food consumption and complementary feeding practices in children aged between 6 and 24 months living in Acrelândia, Acre State, Westhern Brazilian Amazon. Methods: A population-based, cross-sectional study was conducted within an urban area of Acrelândia. Information on sociodemographic conditions, morbidit

8. Iron status and some phagocytes oxidative stress functions in the elderly with or without anemia, carriers of inflammation chronic diseases. / Status férrico e algumas funções do estresse oxidativo de fagócitos em idosos anêmicos ou não, portadores de doenças inflamatórias crônicas
Introdução. A Anemia das Doenças Crônicas (ADC) é uma desordem comum em idosos, freqüentemente multifatorial, e exacerbada por citocinas pró-inflamatórias. Nesta população, o diagnóstico de anemia por deficiência de ferro (ADF) é difícil utilizando-se os testes laboratoriais convencionais, devido à prevalência destes estados crônicos. Espéc

9. ESTUDO MORFOFUNCIONAL DAS CÉLULAS DE SERTOLI DE RATOS ALBINOS TRATADOS COM ETOPOSIDE NA FASE PRÉ-PÚBERE. / Morphological and functional evalution of Sertoli cells from albino treated with etoposide during preopubertal phase. / ESTUDO MORFOFUNCIONAL DAS CÉLULAS DE SERTOLI DE RATOS ALBINOS TRATADOS COM ETOPOSIDE NA FASE PRÉ-PÚBERE. / Morphological and functional evalution of Sertoli cells from albino treated with etoposide during preopubertal phase.
Spermatogenesis is a complex and controlled process in which Sertoli cells play a key role. In the testis, endocrine, paracrine and autocrine mechanisms that control spermatogenesis occurrence. The Sertoli cells synthesize substances which are essential for these mechanisms. Among them is transferrin. This protein is an important iron transporter that binds

10. Cells T immunophenotypic analysis in animal modelo of iron deficiency / Avaliação fenotípica dos linfócitos T em um modelo animal de deficiência de ferro
O ferro é um elemento chave em muitos processos metabólicos, como transporte de oxigênio, síntese de hormônios esteróides, respiração celular, transporte de elétrons, síntese de DNA, proliferação e diferenciação celular e regulação gênica. A deficiência de ferro é a desordem nutricional mais comum afetando aproximadamente um terço da popu

11. Niveis dos receptores soluveis de transferrina e graus de maturidade dos reticulocitos na talassemia alfa+
Background and Objective. It has been suggested that an increased number of young circulating red blood cells (RBC) in a+-thalassemic children could be related to the high frequencies of the a+-thalassemic allele in malaria endemic areas. Reticulocyte (RET) evaluation in this condition, however, has not been performed so far. Our objective was to determine t

12. Soluble transferrin receptor and immature reticulocytes are not useful for distinguishing iron-deficiency anemia from heterozygous beta-thalassemia
A deficiência de ferro e a beta-talassemia heterozigótica são importantes causas de microcitose e hipocromia. São propostos dois parâmetros laboratoriais para auxiliar na diferenciação entre essas anemias. O número de reticulócitos altamente imaturos e níveis do receptor solúvel da transferrina foram determinados em pacientes com anemia ferropriva
