13. Thi1, a protein involved on biosynthesis of thiamin in Arabidopsis thaliana: structural analysis of Thi1(A140V) mutant / Thi1, uma proteína envolvida na síntese de tiamina em Arabidopsis thaliana: análises estruturais do mutante Thi1 (A140V)
A forma ativa da vitamina B1, tiamina pirofosfato (TPP), é um cofator indispensável para certas enzimas que atuam no metabolismo de carboidratos e aminoácidos. Sua biossíntese se dá pela formação independente de suas partes componentes pirimidina e tiazol. Em procariotos a via de síntese para vitamina B1 já foi esclarecida, entretanto em eucariotos

14. Deficiência de tiamina e isolamento social afetam aspectos do comportamento motor e níveis centrais de GABA e glutamato
The main phenomenon approached in this study is the motor behavior, evaluated after two different types of environmental stimuli, the consumption of diet deficient in B1 vitamin and/or social isolation. The B1 vitamin, thiamine, is an essential nutrient for the nervous tissue. In previous studies, our research group has shown that the maternal thiamine defic

15. ProduÃÃo de Ãcido CÃtrico utilizando glicerol residual da produÃÃo de biodiesel como substrato / Production of citric acid using residual glycerol from biodiesel production as a substrate
Due to government financial incentives, which boost the production of biodiesel, there has been a large scale production of this fuel. However, this growth has proved to be exaggerated, rising a worrying factor: the destination of the glycerol excess from biodiesel production. Such concern is clearly shown to prove an important fact: for every ton of biodies

16. Evaluation of turbidimetric and nephelometric techniques for analytical determination of n-acetylcysteine and thiamine in pharmaceutical formulations employing a lab-made portable microcontrolled turbidimeter and nephelometer
A análise turbidimétrica e nefelométrica sequencial (STN) para duas aplicações analíticas empregando um nefelômetro e turbidímetro microcontrolado portátil (PMTN) é proposta. O PMTN é constituído de diodos emissores de luz, fotodiodos, microcontrolador como unidade de processamento central (CPU) e um um LCD (liquid crystal display) como amostrado

17. Rearing the southern green stink bug using an artificial dry diet and an artificial plant.
Laboratory and greenhouse studies were conducted with an artificial dry diet to rear nymphs, and with an artificial plant as substrate for egg laying by the southern green stink bug, Nezara viridula (L.). The artificial diet was composed of: soybean protein (15 g); potato starch (7.5 g); dextrose (7.5 g); sucrose (2.5 g); cellulose (12.5 g); vitamin mixture

18. Avaliação nutricional e do consumo alimentar de trabalhadoras de enfermagem em um hospital público de Fortaleza / Nutritional assessment and dietary intake of nurses in a public hospital in Fortaleza
Accumulate evidence that the qualitative characteristics of the diet are important in defining the health status of the general population. The increasing prevalence of obesity and chronic diseases it is perceived increasingly important to study the contribution of this factor in worker health. Relationship between chronic diseases and body fat accumulation

19. Perfil epidemiológico do beribéri notificado de 2006 a 2008 no estado do Maranhão, Brasil e as ações de enfrentamento / Epidemiological profile of beriberi reported from 2006 to 2008 in the State of Maranhão, Brazil and its preventing and controlling strategies
Introduction: Beriberi is a disease caused by a deficiency of thiamine (vitamin B1) which, although easily treatable, may lead to death. There had been no register of beriberi outbreaks in Brazil for at least seventy years. Objective: To describe the epidemiological profile of reported beriberi cases in the State of Maranhão. Method: A descriptive retrospec

20. Restrição de tiamina no período perinatal, induz, em animais na idade adulta, déficits motores e alterações em parâmetros centrais GABAérgicos e glutamatérgicos
Thiamine, also known as vitamin B1, is an essential nutrient required by all tissues including the nervous system. In a previous study our group has shown that the maternal thiamine deficiency can lead to decrease in brain weight and changes in central neurochemical parameters assessed in the offspring. Considering the importance of thiamine to brain develop

21. Seleção de leveduras potencialmente produtoras de vitaminas do complexo B e estudo do processo fermentativo visando aplicação em alimentação animal / Screening of potential B-vitamin producer yeasts and the study of fermentation process for feed application
The present work had as the main the objective, the isolation and selection of potential B-vitamin producer yeast and the study of fermentative process for B-vitamin production for feed application. Among 267 isolated strains, one was selected as extracellular thiamine producer and the strain Candida sp. LEB 130 as riboflavin and biotin producer. In the stud

22. Desinfecção de explantes e cultivo in vitro de Piretro da Dalmácia (Chrysanthemum cinerariaefolium Vis. cv. Vacaria) / Pyrethrum (Chrysanthemum cinerariaefolium cv. Vacaria) explants disinfection and cultivation in vitro
The activities that involve floriculture have distinguished positively in the economic scenario of the Brazilian agribusiness. Among the plant species used for that purpose it can be distinguished the species belonging to the botanical family Asteraceae, mainly from the genus Chrysanthemum. The species C. cinerariaefolium Vis. is worldwide cultivated in orde

23. Avaliação do efeito da tiamina ou benfotiamina sobre sistema antioxidante hepático em modelo experimental agudo de alcoolismo / Evaluation of the effect of thiamine or benfotiamina on liver antioxidant system in an experimental model of acute alcoholism.
The proposed arrangements for the range of deleterious actions caused by ethanol are due to biochemical changes occurring in hepatocytes such as: 1) increasing in generation of free radicals; 2) production exacerbated an intermediary of high reactivity from peroxidation of macromolecules, and 3) depletion of substances of antioxidant defense system. The use

24. Aspectos funcionais do gene thi1 em plantas selvagens e mutantes de Arabidopsis thaliana (Brassicaceae) / Functional aspects of thi1 gene in wild-type and mutant plants of Arabidopsis thaliana (Brassicaceae)
O gene thi1 foi isolado a partir de uma biblioteca de cDNA de A. thaliana devido à sua capacidade de complementar mutantes de E. coli para rotas de reparo de DNA. O posterior seqüenciamento desse gene permitiu a identificação de similaridade com genes de fungos ativados em condições de estresse ou ativados na ausência de tiamina (vitamina B1). A sínt
