1. The first series of cases of ketosis-prone type 2 diabetes (flatbush diabetes) in Brazilian adults
SUMMARY Ketosis-prone type 2 diabetes (KPD) is an emerging form of diabetes mellitus characterized by unprovoked ketoacidosis, absence of autoimmunity and beta-cell dysfunction. The KPD may improve after initial glycemic compensation and evolve to exogenous insulin independence, most cases were observed in populations with African or Hispanic backgrounds. We

2. Repercussions of low fructose-drinking water in male rats
Abstract Fructose consumption has increased worldwide, and it has been associated with the development of metabolic diseases such as insulin resistance (IR) and steatosis. The aim was to evaluate if lower fructose concentrations may cause pancreatic structural abnormalities, leading to a glucose intolerance without steatosis in male rats. Young male rats ora

3. Leishmania donovani infection activates Toll-like receptor 2, 4 expressions and Transforming growth factor-beta mediated apoptosis in renal tissues
Abstract The present study was aimed to identify the underlying mechanisms of improper renal function in Leishmania donovani infection that causes VL. Mice (BALB/c) were infected with L. donovani and different parameters for proteinuria were assessed. The levels of superoxide anion (O2 -), hydrogen peroxide (H2O2), lipid peroxidation (MDA), inflammatory cyto

4. Role of microRNAs in the treatment of type 2 diabetes mellitus with Roux-en-Y gastric bypass
The aim of this study was to investigate the effect of Roux-en-Y gastric bypass (RYGB) on the peripheral blood microRNAs (miRNAs) of patients with type 2 diabetes mellitus (T2DM). miRNAs are small 20- to 22-nucleotide (nt) noncoding RNAs. They constitute a novel class of gene regulators that negatively regulate gene expression at the post-transcriptional lev

5. SENSIBILIDADE INSULÍNICA E FUNÇÃO DA CÉLULA BETA EM INDIVÍDUOS HETEROZIGÓTICOS PARA UMA MUTAÇÃO NO GENE DO RECEPTOR DO GHRH. / INSULIN SENSITIVITY AND CELL FUNCTION BETA IN A HETEROZYGOUS MUTATION IN THE GHRH RECEPTOR.
GH e o fator de crescimento semelhante à insulina tipo I (IGF-I) apresentam funções sinérgicas sobre a síntese protéica e massa muscular. No tecido adiposo, o GH estimula a lipólise e oxidação lípidica, enquanto o IGF-I estimula a diferenciação dos pré adipócitos em adipócitos. No metabolismo glicídico, GH e IGF-I têm ações opostas, sendo

6. Effect of high-fat diets on body composition, lipid metabolism and insulin sensitivity, and the role of exercise on these parameters
Dietary fat composition can interfere in the development of obesity due to the specific roles of some fatty acids that have different metabolic activities, which can alter both fat oxidation and deposition rates, resulting in changes in body weight and/or composition. High-fat diets in general are associated with hyperphagia, but the type of dietary fat seem

7. ADIPOCINAS, EXCREÇÃO URINÁRIA DE ALBUMINA, SENSIBILIDADE INSULÍNICA E FUNÇÃO DA CÉLULA BETA NA DEFICIÊNCIA ISOLADA DO HORMÔNIO DE CRESCIMENTO. / ADIPOKINES, URINARY ALBUMIN EXCRETION, INSULIN SENSITIVITY AND BETA CELL FUNCTION IN ISOLATED GROWTH HORMONE DEFICIENCY.
O objetivo deste trabalho foi aprofundar a avaliação da dissociação entre a presença de marcadores de risco cardiovascular (CV) e a ausência de doença CV (DCV) na deficiência isolada do GH (DIGH) por mutação no gene do receptor do hormônio liberador do GH. Foi realizado um protocolo com duas etapas. No primeiro experimento, foram avaliados os nív

8. Avaliação do metabolismo ósseo após transplante alogênico de células tronco hematopoiéticas
O transplante de células tronco hematopoiéticas (TCTH) é uma terapia bem estabelecida para o tratamento de diversas doenças hematológicas benignas e malignas, sendo amplamente realizado em vários países, inclusive no Brasil. Com a sobrevivência dos pacientes transplantados por tempo longo, verifica-se o desenvolvimento de complicações tardias, gera

9. Proximal tubular dysfunction as an indicator of chronic graft dysfunction
New strategies are being devised to limit the impact of renal sclerosis on graft function. Individualization of immunosuppression, specifically the interruption of calcineurin-inhibitors has been tried in order to promote better graft survival once chronic graft dysfunction has been established. However, the long-term impact of these approaches is still not

10. Construção de ferramentas para estudo da possível interação entre interferon-beta e p53. / Construction of tools for study of the possible interaction between interferon-beta and P53.
Formation of tumors it must to combinations of factors. The p53 pathway has an essential role in proliferation control and apoptosis. The interferon-beta (IFNb) is important in modulation of the immunologic response, in the antitumoral effect and in the apoptotic impact in tumor cells. According to literature, IFNb activate the p53 transcription and componen

11. A expressão e atividade da NAD(P)H oxidase em ilhotas pancreáticas de ratos tratados com dieta hiperlipídica. / NAD(P)H oxidase expression and activity in pancreatic islets from rats treated with high fat diet.
Feeding animals with high fat diet containing lard causes obesity, insulin resistance and dysfunction of pancreatic beta cells. High fat diet induces oxidative stress and modulates NAD(P)H oxidase expression and activity in many tissues. This enzyme may be involved in many pathophysiological processes. The objective of this study was to evaluate the action o

12. Obtention of human pancreatic islets for transplantation through an increase in cell mass and an immunoisolation with biocompatible microcapsules / Ilhotas pancreáticas humanas viáveis para o transplante através do aumento da massa de células e do imunoisolamento com microcápsulas biocompatíveis
Islet transplantation has been proposed as a promising therapeutic strategy for the cure of type 1 diabetes mellitus (DM), however, its application to all diabetic patients is still not possible due to the limited source of islets or β cells and to the need of an immunosuppressive treatment of the recipient to avoid graft rejection. The use of immunosup
