Alterações no Sistema de Fibras Elásticas da Fáscia Endopélvica de Paciente Jovem com Prolapso Uterino

É apresentado um caso de prolapso do útero de 2º grau em paciente de 18 anos, virgem. Durante o ato cirúrgico corretivo (cirurgia de Gillian) foram recolhidas amostras dos ligamentos e fáscias para avaliação do sistema de fibras elásticas. Foram demonstradas alterações estruturais nas fibras elásticas semelhantes às que ocorrem no envelhecimento, o que promove o enfraquecimento do tecido conjuntivo induzindo ao defeito de suporte do assoalho pélvico.

Enteroparasitoses, Anemia e Estado Nutricional em Grávidas Atendidas em Serviço Público de Saúde

Objetivos: estimar a freqüência de enteroparasitoses em gestantes de pré-natal de baixo risco e sua associação com anemia, estado nutricional, escolaridade e saneamento (fossa sanitária) no domicílio. Métodos: a partir de amostra de 316 gestantes que iniciaram o pré-natal de baixo risco do ambulatório de pré-natal do Instituto Materno Infantil de Pernambuco (IMIP) no período de maio de 2000 a julho de 2001, determinaram-se, por meio de um desenho de corte transversal, as freqüências de enteroparasitoses (método Hoffman, em única amostra) e de anemia (Hb <11,0 g/dL), o estado nutricional (índice de massa corporal - IMC - ajustado para idade gestacional) e indicadores sociais (escolaridade e presença de fossa sanitária em domicílio). Resultados: a freqüência de enteroparasitoses entre estas pacientes foi de 37,0%, sendo 31,6% dos casos positivos representados por monoparasitas. As espécies de parasitos mais freqüentes foram Entamoeba histolytica (13,3%) e Ascaris lumbricoides (12,0%). Detectaram-se 55,4% de gestantes anêmicas, 25,0% de desnutridas e 24,1% com sobrepeso ou obesidade. Houve associação estatisticamente significativa entre enteroparasitose e escolaridade. Não se observou, por outro lado, associação entre anemia, estado nutricional materno, presença de fossa sanitária em domicílio e enteroparasitoses. Conclusões: constataram-se freqüência elevada de enteroparasitoses e anemia, sem, entretanto, haver associação entre estas ocorrências. A escolaridade esteve estatisticamente relacionada com a presença de parasitos intestinais.

Influence of tail biting on weight gain, lesions and condemnations at slaughter of finishing pigs

The present study assessed the association of tail-biting lesions in finishing pigs with weight gain, occurrence of locomotion or respiratory disorders and abscesses during finishing period, and carcass condemnation at slaughter. The study was carried out on 4 different farms. For each animal with a tail biting lesion, two control pigs were selected. The total number of animals in the study was 312, with 104 of them being tail-bitten. Tail lesions were classified according to the degree of severity into four scores: score 0 -normal tail withou lesion; score 1-3 - increasing lesion severity, and score 4 - healed lesions. Overall, the occurrence of severe tail lesions (score 3) varied from 55 to 73% of tail-bitten pigs among farms. On all farms, healing of tail lesions was observed in 95% to 100% of the animals at the evaluation performed within 41-43 days after the commencement of the study. In two out of the four evaluated farms, pigs with score of 3 showed lower weight gain (P<0.05) compared with score 0 pigs. Before slaughter, the occurrence of locomotion problems and nodules/abscesses was associated (P<0.05) with the presence of tail-biting lesions. At slaughter, tail-biting lesions were associated (P<0.05) with the presence of abscesses, lung lesions (pleuritis and embolic pneumonia) or arthritis in carcasses. Carcass condemnation was associated with the presence of tail-biting lesions (P<0.05). Overall, carcass condemnation rate was 21.4%, of which animals with tail-biting lesions accounted for 66.7% of condemnations. Among the animals diagnosed with cannibalism at farm level, only two had not healed their lesions at slaughter. The fact that there were a lot of carcass condemnations, despite the fact that tail-bitten animals had no more active lesions, suggests that different situations may be observed between the field and slaughter, reinforcing the need to analyze pigs both at farm and slaughter to allow proper assessment of losses related to tail biting. Collectively, the observations of the present study show that complications associated with tail-biting found in slaughterhouses are probably underestimating field prevalence.

O que os santos podem fazer pela antropologia?

O artigo sustenta que os santos podem servir de eixo a uma abordagem mais etnográfica e radical da antropologia da religião. De praxe, essa subdisciplina está excessivamente pautada pelas concepções de apenas um tipo de nativos: teólogos, sacerdotes, especialistas. Doutrinas estabelecidas servem como referência, e a religião comum vira assim uma religião popular, subalterna ou desviante. Os santos, personagens locais que no entanto atravessam fronteiras entre credos e são por sua vez subalternos nas elaborações teológicas, podem ser vistos como atores essenciais dentro de uma rede de relações (do tipo das propostas pela actor-network theory), a unir mitos, devotos, lugares, objetos ou personagens sagrados, rituais, doutrinas e, como um limite externo, Deus. Essa rede, sugiro, deve se reivindicar como objeto prioritário dos estudos sobre religião.

Efeito do tempo de fornecimento de ração suplementada com óleo de linhaça sobre a composição físico-química e de ácidos graxos em cabeças de tilápias do Nilo (Oreochromis niloticus)

Este trabalho teve como objetivo realizar um estudo sobre a composição físico-química e, especialmente sobre a composição de ácidos graxos nos lipídios totais de cabeças de tilápias (Oreochromis niloticus), submetidas a diferentes tempos (0, 10, 20, 30 dias) de fornecimento de ração suplementada com óleo de linhaça (fonte do ácido a-linolênico, 18:3n-3 LNA), em substituição ao óleo de girassol. Não houveram diferenças (P>0,05) entre os teores de umidade, cinza, proteína e lipídios totais para os diferentes tratamentos (tempos de fornecimento). Os teores de lipídios totais das cabeças variaram de 8,41 a 10,13% e foi encontrado um total de 27 ácidos graxos nestes lipídios para todos os tratamentos. Os ácidos graxos majoritários foram 18:2n-6 (29,66 a 32,11%), 18:1n-9 (29,68 a 31,71%) e 16:0 (15,53 a 16,63%). Houve um aumento nos teores percentuais do ácido 18:3n-3, da somatória de ácidos graxos ômega-3 e uma diminuição da razão n-6/n-3, com diferenças (P<0,05) entre o tratamento A (tempo zero) e os demais tratamentos que receberam óleo de linhaça. Não houveram diferenças (P>0,05) entre os tratamentos para a razão entre ácidos graxos polinsaturados e saturados (AGPI/AGS).

Isolation of a yeast strain able to produce a polygalacturonase with maceration activity of cassava roots

The objective of the present study was the isolation of a yeast strain, from citrus fruit peels, able to produce a polygalacturonase by submerged fermentation with maceration activity of raw cassava roots. Among 160 yeast strains isolated from citrus peels, one strain exhibited the strongest pectinolytic activity. This yeast was identified as Wickerhamomyces anomalus by 5.8S-ITS RFLP analysis and confirmed by amplification of the nucleotide sequence. The yeast produced a polygalacturonase (PG) in Erlenmeyer shake flasks containing YNB, glucose, and citrus pectin. PG synthesis occurred during exponential growth phase, reaching 51 UE.mL-1 after 8 hours of fermentation. A growth yield (Yx/s) of 0.43 gram of cell dry weight per gram of glucose consumed was obtained, and a maximal specific growth rate (µm) of 0.346 h-1 was calculated. The microorganism was unable to assimilate sucrose, galacturonic acid, polygalacturonic acid, or citrus pectin, but it required glucose as carbon and energy source and polygalacturonic acid or citrus pectin as inducers of enzyme synthesis. The crude enzymatic extract of Wickerhamomyces anomalus showed macerating activity of raw cassava. This property is very important in the production of dehydrated mashed cassava, a product of regional interest in the province of Misiones, Argentina.

Antioxidant capacity and chemical composition in seeds rich in omega-3: chia, flax, and perilla

The chemical composition and antioxidant capacity of five seeds, chia, golden flax, brown flax, white perilla, and brown perilla, were determined. The chemical properties analyzed included moisture, ash, crude protein, carbohydrates, total lipids, fatty acids, and antioxidant capacity (ABTS•+, DPPH•, and FRAP). The results showed the highest amounts of protein and total lipids in brown and white perilla. Perilla and chia showed higher amounts of alpha-linolenic fatty acid than those of flaxseed varieties, ranging between 531.44 mg g-1 of lipids in brown perilla, 539.07 mg g-1 of lipids in white perilla, and 544.85 mg g-1 of lipis in chia seed. The antioxidant capacity of the seeds, evaluated with ABTS•+, DPPH• , and FRAP methods, showed that brown perilla had greater antioxidant capacity when compared with white perilla, flax, and chia seeds.

Incorporation and profile of fatty acids in tilapia fillets (Oreochromis niloticus) fed with tung oil

The acceptance of tung oil enriched diet and the incorporation of conjugated linolenic acid - CLnA into fillets of Genetically Improved Farmed Tilapia (GIFT) were investigated. The diet was well accepted, and after 10 days CLnA was incorporated into the fillets with a 1.02% content of total fatty acids (FA). In addition, biosynthesis of the conjugated linoleic acid isomers - CLA (0.31% of fillet total FA content) from CLnA, and the presence of alpha-linolenic acid - LNA (1.08% of fillet total FA content), eicosapentaenoic acid - EPA (2.85% of fillet total FA content) and docosahexaenoic acid - DHA (3.08% of fillet total FA content) were observed. Therefore, the consumption of this fish can increase the intake of different FA (CLnA, CLA, LNA, EPA and DHA), which play an important role in human metabolism.

Applying life cycle management of colombian cocoa production

The present research aims to evaluate the usefulness of the application of Life Cycle Management in the agricultural sector focusing on the environmental and socio-economic aspects of decision making in the Colombian cocoa production. Such appraisal is based on the application of two methodological tools: Life Cycle Assessment, which considers environmental impacts throughout the life cycle of the cocoa production system, and Taguchi Loss Function, which measures the economic impact of a process' deviation from production targets. Results show that appropriate improvements in farming practices and supply consumption can enhance decision-making in the agricultural cocoa sector towards sustainability. In terms of agri-business purposes, such qualitative shift allows not only meeting consumer demands for environmentally friendly products, but also increasing the productivity and competitiveness of cocoa production, all of which has helped Life Cycle Management gain global acceptance. Since farmers have an important role in improving social and economic indicators at the national level, more attention should be paid to the upgrading of their cropping practices. Finally, one fundamental aspect of national cocoa production is the institutional and governmental support available for farmers in face of socio-economic or technological needs.

Prevention of enzymatic browning of yacon flour by the combined use of anti-browning agents and the study of its chemical composition

Yacon roots present functional properties because of the high levels of fructooligosaccharides (FOS), which are considered as prebiotic fibers. In addition, yacon roots are rich in phenolic compounds. During the processing of yacon, the freshly cut surface undergoes rapid enzymatic browning. Control of enzymatic browning during processing is very important to preserve the appearance of yacon flour. In this study, it was evaluated the combined effect of anti-browning agents (ascorbic acid, citric acid and L-cysteine) on the inhibition of enzymatic browning of yacon, using Response Surface Methodology. The yacon pre-treated with anti-browning agents in concentrations of 15.0 mM for ascorbic acid, 7.5 mM for citric acid and 10.0 mM for L-cysteine was used for the processing of flour. Yacon flour presented an attractive color and good sensory properties, without residual aroma. The contents of FOS and phenolic compounds obtained in yacon flour were 28.60 g.100 g- 1 and 1.35 g.100 g- 1. Yacon flour can be considered as a potential functional food, especially due to high levels of FOS, which allows for its use in formulation of various foods.

Effect of Amaranth addition on the nutritional composition and consumer acceptability of extruded provitamin A-biofortified maize snacks

The objective of this study was to determine the effect of adding Amaranth leaf powder on the nutrient content and consumer acceptability of extruded provitamin A-biofortified (PVA) maize snacks. Flours of four varieties of PVA maize were composited with Amaranth leaf powder at 0, 1 and 3% (w/w) substitution of, respectively, and extruded into snacks. The ash content of the snacks increased from 0.53 g/100 g-0.58 g/100 g to 0.650 g/100g-89 g/100 g and protein content increased from 9.12 g/100 g-10.94 g/100 g when Amaranth was increased from 0% to 3%. Similarly, lysine content increased from 0.10 g/100 g to 0.17 g/100 g, whilst methionine increased from 0.14 g/100 g to 0.19 g/100 g. The provitamin A content of the snacks ranged from 1.29 µg/g to 1.40 µg/g at 0% Amaranth and 1.54 µg/g to 1.78 µg/g at 3% Amaranth. The acceptability of the snacks decreased with increasing Amaranth concentration, only a very small proportion (2-8%) of the panel liked the snacks extremely. PVA maize with added Amaranth leaf powder has a potential for use in nutritious and healthy extruded snacks, but the consumer acceptability of the snacks should be improved.

Prevention of contrast induced nephropathy with sodium bicarbonate (the PROMEC study)

Introduction: Contrast-induced nephropathy is a common complication of radiographic procedures. Different measures have been used to avoid this damage, but the evidence is controversial. New investigations are required to clarify it. We investigated the efficacy and safety of sodium bicarbonate solution compared with sodium chloride solution to prevent contrast induced nephropathy in patients with or at risk of renal dysfunction. Methods: A prospective, single-center, randomized clinical trial conducted from May 1, 2007 to February 8, 2008. Inpatients in a tertiary center, scheduled to undergo a procedure with the nonionic radiographic contrast agent iohexol. There were 220 patients with serum creatinine levels of at least 1.2 mg/dL (106.1 µmol/L) and/or type 2 diabetics, who were randomized to receive an infusion of sodium chloride (n = 113) or sodium bicarbonate (n = 107) before and after contrast dye administration. The intervention were "A" group received 1 ml/kg/hour of normal saline solution, starting 12 hours before and continuing 12 hours after iohexol contrast. "B" group received 3 ml/kg of sodium bicarbonate solution (150 mEq/L) one hour prior to procedure and then drip rate was decreased to 1 ml/kg/hour until 6 hours post procedure. Our main outcome measure was change in serum creatinine. Results: The mean creatinine value after the procedure was 1.26 mg/dL in the saline group and 1.22 mg/dL in the bicarbonate group (mean difference: 0.036; CI 95%: -0.16 to 0.23, p = 0.865). The diagnosis of contrast-induced nephropathy, defined by increase in serum creatinine on 25% or more within 2 days after administration of radiographic contrast, was done in twelve patients (12%) in the bicarbonate group and eighth patients (7.1%) in the saline group (RR: 1.68, CI 95%: 0.72 to 3.94). Conclusion: Our investigation showed that there were no differences between normal saline solution (extended infusion) vs. bicarbonate solution for nephroprotection.
