PRODUCTION OF A PRODUCT SIMILAR TO GELATIN FROM CHICKEN FEET COLLAGEN

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Chicken feet can be used as an alternative source of collagen for the development of new products. In this sense, the aim of this study was the production of a product similar to gelatin from collagen extracted from chicken feet and the evaluation of sensory quality. The products were produced in two distinct flavors, with grape flavor called GU and pineapple flavor called GA. Subsequently, we compared these formulations with gelatin of a trademark established in the market. We used in the verification of sensory acceptability of products a hedonic scale of 9 points and the availability of consuming the product by 30 untrained tasters. According to the results, all formulations showed good levels of acceptability, indicating the collagen from chicken feet as an alternative source of high quality in the production of gelatin.33612891300Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)UNINOVECoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Wine clarification from Spondias mombin L. pulp by hollow fiber membrane system

The aim of this work was to study the caja (Spondias mombin L.) wine clarification using a hollow fiber membrane system. Two caja wines clarified with bentonite clay were used for comparison. Transmembrane pressures of 0.40 and 0.60 bar were used. Ninety-five percent of caja wine colors were reduced at both transmembrane pressures and 66% with bentonite clay clarification. Caja wine clarified with the membrane process was light yellow; but caja wine clarified with bentonite clay had a turbid appearance. This works showed that it is possible to clarify the caja wine with the membrane process and that this process did not change the quality of the wine and retained color, aroma and flavor from the caja fruits. The membrane clarification enables a continuous process for caja wine production. (C) 2007 Elsevier Ltd. All rights reserved.42111516152

Molecular analysis of homocystinuria in Brazilian patients

Background: Cystathionine beta-synthase (CBS) deficiency is the most common cause of homocystinuria. However, no data are available concerning the molecular basis of this disease in Brazilian populations.Methods: We studied 14 Brazilian patients from 11 unrelated families using a combined screening approach, involving restriction analysis, single-strand conformational polymorphism (SSCP) scanning, and sequencing.Results: All patients presented homocysteine levels higher than 200 mu mol/l before the beginning of treatment. the most common CBS gene mutations, p.G307S (c.919G > A) and p.1278T (c.833T > C), were evaluated and the allele c.919A was not found. One allele with the c.844 ins68 (4.5%) in the CBS gene was found. Three families (6 patients) presented the allele c.833 C (13.6%), without the insertion in the heterozygous state. SSCP scanning and sequencing showed 3 alleles p.T191M (13.64%) in 2 families. One allele with a novel mutation was found in exert 4 (c.168T > A) of the CBS gene (4.5%). We also analyzed c.677C > T and c.1298A > C polymorphisms to the methylenetetrahydrofolate reductase (MTHFR) gene and the 2756A > G polymorphism in the methionine synthase (MTR) gene. the frequencies of mutated alleles were: 50% c.677T and 18.2`x, c.1298C for MTHFR, and 27.3% c.2756G for MTR.Conclusion: in spite of the high level of racial mixing in the country, Brazilian homocystinuric patients did not present a high prevalence of the most common mutations described in the literature.

Prenatal exposure to misoprostol and vascular disruption defects: A case-control study

Prenatal exposure to misoprostol has been associated with Moebius and limb defects. Vascular disruption has been proposed as the mechanism for these teratogenic effects. The present study is a multicenter, case-control study that was designed to compare the frequency of prenatal misoprostol use between mothers of Brazilian children diagnosed with vascular disruption defects and matched control mothers of children diagnosed with other types of defects. A total of 93 cases and 279 controls were recruited in eight participating centers, Prenatal exposure was identified in 32 infants diagnosed with vascular disruption defects (34.4%) compared with only 12 (4.3%) in the control group (P < 0.0000001). Our data suggest that prenatal exposure to misoprostol is associated to the occurrence of vascular disruption defects in the newborns, 2000 Wiley-Liss, Inc.95430230

Inter-relações de nitrogênio e fósforo na capacidade de combinação e na seleção em milho

Tem sido observada, em milho, a redução da absorção de nitrogênio (N), por causa da deficiência de fósforo (P), mas o efeito dessa combinação na seleção de genitores ainda precisa de estudos. Os objetivos deste trabalho foram avaliar os efeitos das inter-relações de P e N na capacidade de combinação e seleção de genitores de milho. As 28 combinações híbridas (CH), obtidas de um dialelo completo entre oito genótipos de milho e três testemunhas, foram avaliadas em quatro ambientes, obtidos pelas combinações de alta e baixa disponibilidade de P e N. Avaliaram-se o rendimento de grãos (RG) e as características secundárias: altura de plantas (AP) e espigas (AE), índice de colheita (IC), peso volumétrico (PV), prolificidade (PRL) e massa seca da parte aérea (MSPA). O efeito do estresse de N no RG foi similar em baixo e alto P. O genótipo P3041 apresentou alto RG em todos os ambientes. As correlações genéticas das características secundárias com o RG foram afetadas pelos ambientes. Em alto P, a capacidade geral de combinação (CGC) foi significativa para RG apenas em alto N. Em baixo P, a CGC apresentou significância em ambos os níveis de N. Os genótipos AG1051 e P3041 tiveram estimativas positivas de CGC em todos os ambientes. Conclui-se que, para o rendimento de grãos, a CGC somente não é importante em alto P e baixo N e a CEC não é importante em estresse de P ou N
