Amazonian Fruits: An Overview of Nutrients, Calories and Use in Metabolic Disorders  [PDF]
Moacir Couto de Andrade Júnior, Jerusa Souza Andrade
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.517182
Abstract: Amazonian fruits are outstanding in quality. They are consumed as true delicacies of nature by the Brazilian population. Besides their attractive attributes, i.e. appearance, different textures and distinctive flavors, their nutritional value is diversified in the type of calories and the functional food ingredients. In addition to being very palatable, Amazonian fruits provide energy-rich macronutrients (lipids, proteins and carbohydrates), micronutrients (minerals, water-soluble vitamins and fat-soluble vitamins), prebiotics (dietary fibers, especially pectin), bioactive substances (carotenoids and polyphenols), variety in the diet and improvement in the organoleptic properties and digestibility of (mixed) foods. This study first aimed to review concepts applicable to nutritional constituents and caloric contents of Amazonian fruits. It also attempted to clarify the potential use of these fruits in metabolic disorders (i.e. diabetes mellitus and/or obesity). To fulfill these purposes, 12 fruits were chosen for their dietetic significance in the Brazilian Amazonia.
Biochemical Changes of Cubiu Fruits (Solanum sessiliflorum Dunal, Solanaceae) According to Different Tissue Portions and Ripening Stages  [PDF]
Moacir Couto de Andrade Júnior, Jerusa Souza Andrade, Suely de Souza Costa
Food and Nutrition Sciences (FNS) , 2016, DOI: 10.4236/fns.2016.712111
Abstract: Cubiu fruits (Solanum sessiliflorum Dunal, Solanaceae) are known for their high nutritional value and low caloric content. This work aimed at evaluating biochemical indices of cubiu fruits according to different tissues (peel, pulp and placenta) and ripening stages (green, turning, ripe and fully ripe). The fruits were randomly harvested to investigate sensory aspects (colorimetry, blanching effect, pigments) and biochemical indices (moisture and dry matter, Total Soluble Solids (TSS), pH, Titratable Acidity (TA), TSS/TA ratio, ascorbic acid, Alcohol-Insoluble Solids (AIS), pectinesterase activity and pectin content). The analyses were performed at the laboratory of Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, Brazil. The blanching process preserved pulp colors at all ripening stages. Chlorophylls were higher in green peels; flavonoids and carotenoids, in fully ripe peels. Anthocyanins were entirely absent. Pulp (turning fruits) showed the highest moisture content (91.05), followed by ripe pulp (90.70) and fully ripe pulp (90.62). Pulp TSS changed little whereas placenta TSS declined and were associated with increased TA and pH reduction (fully ripe fruits). Pulp pH and TA varied little whereas placenta pH was notably low and TA was remarkably high (fully ripe fruits). Pulp TSS/TA ratio showed predominance of TSS while in placenta, there was predominance of organic acids. AIS, precursors of pectin, were stable during ripening. The statistical analysis of dietary fiber content showed one modal value in the AIS. In pulp, pectinesterase activity correlated inversely with pectin content. Cubiu fruits were significant sources of bioactive compounds, e.g. chlorophylls, flavonoids and carotenoids, predominantly in the peel and the pulp; soluble functional fibers, e.g. pectin (g/100 g fresh weight), particularly in the green peel (1.00) and the fully ripe pulp (1.12), and other versatile molecules, e.g. ascorbic acid (mg/100 g fresh weight), especially in the fully ripe peel (32.45) and placenta (24.84) and the turning placenta (21.27). Cubiu fruits are rich in ascorbic acid and should be included in the human diet.

Abstract: steel cylindrical silos, when empty, are susceptible to the crumpling of the sheeting of the cylinder by the wind action. this paper compares the effects of internal and external stiffening with columns on the aerodynamic behavior of cylindrical silos with conical roof. the theoretical studies leaded to wind tunnel experiments, which have been carried out on two types of scaled silo models, one with smooth surface (internal stiffening), the other with ribbed surface (external stiffening), both with two geometric height/diameter ratio of cylinder (0.5 and 1.0) and a conical roof pitch equal to 27o. based on the information gained during these experiments, external coefficients of pressure and drag and lift coefficients are derived for the cylinders, as well as the drag and lift coefficients for the conical roofs. with this, it is identified the best stiffening arrangement for an optimum design of cylindrical silos to resist wind loads. the final result is an updated data set, originated from tests with geometric and aerodynamic characteristics well conditioned, which are applicable to a variety of cylindrical silos.

Andrade Júnior, Péricles Morais de;
História (S?o Paulo) , 2010, DOI: 10.1590/S0101-90742010000100007
Abstract: this article aims to analyze the social distinctions incorporated in the catholicism in the province of sergipe del rey during the nineteenth century. the analysis will be centered in the criteria of admission of two active religious brotherhoods in the city of estancia in sergipe, brazil. the research shows that there was a population divided between the brotherhoods of the blessed sacrament and our lady of the rosary, reflections of a more diversified social hierarchy about the criteria of race, wealth and social prestige. the space presented meanings in so far as the city reproduced, symbolically, the society and its organization in social strata. in other words, we notice that the catholic religious field in the population of estancia followed the mechanisms of expression of the segregation and presented itself as representative of the oppositions between the social groups, which were characterized by associations which defined the social position and the tastes of their members.

Torna tua a heran?a de teu pai: o Nome-do-Pai na psicanálise lacaniana
Andrade Júnior, Moisés de;
Psicologia Clínica , 2011, DOI: 10.1590/S0103-56652011000200012
Abstract: this article studies some key moments in the development of the lacanian concept name-of-the-father, starting with freud’s works about the repression, demonstrating the importance of freud’s thinking for the development of the concept. three periods of his trajectory are investigated: the name-of-the-father as the incest interdiction; the name-of-the-father pluralized as establisher of the unconscious structured as a language; finally, his role in the borromean knots theory. to do so, we will investigate the transfinite mathematics, whose logic pervades some of the lacanians elaborations. the orientation of this line of thought will be the possibility of unconscious itself, taken as the repressed material, or as the articulation between significants.

Quantification of the Expression of HIF-1alpha by Real-Time PCR in Rat Hepatocytes Cultures Invaded by Shigella flexneri under Normoxic and Hypoxic Conditions  [PDF]
Camila Bárbara Cantalupo Lima, Sania Alves dos Santos, Dahir Ramos de Andrade Júnior
Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.57052
Abstract: Aim: Shigella flexneri (S. flexneri) is a gram-negative enterobacterium responsible for severe intestinal end systemic infection in humans. The bacteria can reach the liver due to degeneration of the colonic epithelium. Hypoxia is present in many human diseases and can induce the expression of the transcription factor HIF-1alpha that may have a cell protective role. The influence of hypoxia and HIF-1alpha on bacterial infection, studied in this work, is unclear. Hypoxia inducible factor-1alpha (HIF-1alpha) is a transcription factor that acts as a master regulator of gene expression induced by hypoxia. Methods: We compared the ability of S. flexneri to invade rat hepatocytes in primary culture both in normoxic and hypoxic conditions. We evaluated TNF-alpha released by hepatocytes, apoptosis rate and HIF-1alpha expression by confocal microscopy as well as real time PCR technique. Results: We showed that S. flexneri invaded less hepatocytes previously submitted to 24 h hypoxia (6.5% O2) than those cultivated in normoxia (21% O2). S. flexneri also induced HIF-1α expression in hepatocytes, TNF-α secretion and apoptosis. Conclusion: a) Hypoxia alone was not a stimulus to TNF-α secretion, but induced cell apoptosis and HIF-1α expression; b) S. flexneri was able to invade rat hepatocytes and hypoxia apparently influenced significantly bacterial cell invasiveness; c)

Ciência e Tecnologia de Alimentos , 2012, DOI: 10.1590/S0101-20612012005000049
Abstract: cubiu shrubs (solanum sessiliflorum dunal) have drawn the attention of researchers for their biological versatility (preferential heliophilous or facultative ombrophilous shrubs), their capacity to grow in upland or lowland areas, and the good technological quality of their fruits for the food industry. the aim of this study was to verify physicochemical changes in cubiu fruits during maturation. the fruits were harvested from the experimental station of olericulture of the instituto nacional de pesquisas da amaz?nia (inpa), brazil. the analyses were performed in whole cubiu fruits (peel, pulp, and placenta) at four traditional ripening stages (green, turning, ripe, and fully ripe) for the determination of weight, moisture, total solids, total carotenoids, proteins, lipids, and ash. cubiu fruits showed large weight variation, with amodal distribution. the ripe stage was critical to maintain moisture, and from that stage on, water loss became evident. the lipids increased steadily over the four ripening stages, maintaining, however, insignificant calorie content. total carotenoids, proteins, and ash reached the maximum level at the fully ripe stage. with the exception of weight and moisture, all physicochemical changes exhibited the same general behavior, i.e. they increased as the fruits ripened at the four investigated stages.
The influence of the human genome on chronic viral hepatitis outcome
Andrade Júnior, Dahir Ramos de;Andrade, Dahir Ramos de;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2004, DOI: 10.1590/S0036-46652004000300001
Abstract: the mechanisms that determine viral clearance or viral persistence in chronic viral hepatitis have yet to be identified. recent advances in molecular genetics have permitted the detection of variations in immune response, often associated with polymorphism in the human genome. differences in host susceptibility to infectious disease and disease severity cannot be attributed solely to the virulence of microbial agents. several recent advances concerning the influence of human genes in chronic viral hepatitis b and c are discussed in this article: a) the associations between human leukocyte antigen polymorphism and viral hepatic disease susceptibility or resistance; b) protective alleles influencing hepatitis b virus (hbv) and hepatitis c virus (hcv) evolution; c) prejudicial alleles influencing hbv and hcv; d) candidate genes associated with hbv and hcv evolution; d) other genetic factors that may contribute to chronic hepatitis c evolution (genes influencing hepatic stellate cells, tgf-b1 and tnf-alpha production, hepatic iron deposits and angiotensin ii production, among others). recent discoveries regarding genetic associations with chronic viral hepatitis may provide clues to understanding the development of end-stage complications such as cirrhosis or hepatocellular carcinoma. in the near future, analysis of the human genome will allow the elucidation of both the natural course of viral hepatitis and its response to therapy.
