Multivariate Study Of Nile Tilapia Byproducts Enriched With Omega-3 And Dried With Different Methods
The present work aimed at studying the effect of different drying methods applied to tilapia byproducts (heads, viscera and carcasses) fed with flaxseed, verifying the contents of omega-3 fatty acids. Two diets were given to the tilapia: a control and a flaxseed formulation, over the course of 60 days. After this period, they were slaughtered and their byproducts (heads, viscera and carcasses) were collected. These fish parts were analyzed in natura, lyophilized and oven dried. Byproducts from tilapia fed with flaxseed presented docosapentaenoic, eicopentaenoic and docosahexanoic fatty acids as a result of the enzymatic metabolism of the fish. The byproducts from the oven drying process had lower levels of polyunsaturated fatty acids. In the multivariate analysis, the byproducts from fish fed with flaxseed had a greater composition of fatty acids. The addition of flaxseed in fish diets, as well as the utilization of their byproducts, may become a good business strategy. Additionally, the byproducts may be dried to facilitate transport and storage. © 2016 Sociedade Brasileira de Ciencia e Tecnologia de Alimentos, SBCTA. All rights reserved.361182
Insights into the mechanism of MCT8 oligomerization
Mutations in the thyroid hormone transporter monocarboxylate transporter 8 (MCT8) result in MCT8 deficiency, characterized by severe intellectual and motor disability. The MCT8 protein is predicted to have 12 transmembrane domains (TMDs) and is expressed as monomers, homodimers, and homo-oligomers. This study aimed to delineate the mechanism o

Genetic Diversity Of Pacu And Piapara Broodstocks In Restocking Programs In The Rivers Paraná And Paranapanema (brazil)
The genetic diversity of Piaractus mesopotamicus (pacu) and Leporinus elongatus (piapara) broodstocks used in restocking programs in the rivers Paraná and Paranapanema is analyzed. One hundred and twenty specimens (two broodstocks of each species) from fish ponds in Palotina PR Brazil and in Salto Grande SP Brazil were assessed. Ten primers produced 96 fragments, comprising 68 (70.83%) and 94 (97.92%) polymorphic fragments for P. mesopotamicus and L. elongatus broodstocks, respectively. Differences (p <0.05) in the frequency of 15 and 27 fragments were detected for each species, without exclusive fragments. Shannon Index (0.347-0.572) and the percentage of polymorphic fragments (57.3%-94.8%) revealed high intra-population genetic variability for all broodstocks. Results of molecular variance analyses (AMOVA) showed that most variations do not lie between the broodstocks but within each broodstock (89%). Genetic (0.088 and 0.142) and identity (0.916 and 0.868) distance rates demonstrated similarity between the broodstocks of each species, corroborated by Fst (0.1023 and 010.27) and Nm (4.18 and 4.33) rates, with a slight genetic difference due to genic flux. High intrapopulation genetic variability and similarity between the broodstocks of each species was also detected, proving a common ancestry.3742365237
Validação Da Versão De 36 Itens Do Who Disability Assessment Schedule 2.0 (whodas 2.0) Para A Avaliação De Incapacidade E Funcionalidade Da Mulher Associada à Morbidade Materna
Conselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgico (CNPq)To validate the translation and adaptation to Brazilian Portuguese of 36 items from the World Health Organizaton Disability Assessment Schedule 2.0 (WHODAS 2.0), regarding their content and structure (construct), in a female population after pregnancy. Methods This is a validation of an instrument for the evaluation of disability and functioning and an assessment of its psychometric properties, performed in a tertiary maternity and a referral center specialized in high-risk pregnancies in Brazil. A sample of 638 women in different postpartum periods who had either a normal or a complicated pregnancy was included. The structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while the content and relationships among the domains were assessed through Pearson’s correlation coefficient. The sociodemographic characteristics were identified, and the mean scores with their standard deviations for the 36 questions of the WHODAS 2.0 were calculated. The internal consistency was evaluated byCronbach’s α. Results Cronbach’s α was higher than 0.79 for both sets of questons of the questionnaire. The EFA and CFA for the main 32 questions exhibited a total variance of 54.7% (Kaiser-Meyer-Olkin [KMO] measure of sampling adequacy = 0.934; p < 0.001) and 53.47% (KMO = 0.934; p < 0.001) respectively. There was a significant correlation among the 6 domains (r = 0.571–0.876), and a moderate correlation among all domains (r = 0.476–0.694). Conclusion The version of the WHODAS 2.0 instrument adapted to Brazilian Portuguese showed good psychometric properties in this sample, and therefore could be applied to populations of women regarding their reproductive history. © 2017 by Thieme-Revinter Publicações Ltda, Rio de Janeiro, Brazil.3924452471142/2011-5, CNPq, Conselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgicoConselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgico (CNPq
Heterosis and combining ability for ear yield in a diallel cross among six maize varieties
Este estudo teve o objetivo de estimar os efeitos das capacidades geral e especĂfica de combinação, e os valores de heterose, na produção de espigas de cruzamentos dialĂ©licos parciais entre seis variedades de milho (Zea mays L.) em melhoramento, no Centro Nacional de Pesquisa de Milho e Sorgo, (CNPMS), em Sete Lagoas, MG. Os tratamentos compreenderam as variedades CMS 05, CMS 04, CMS 22, CMS 11, CMS 12 e CMS 28, alĂ©m dos seus quinze hĂbridos intervarietais (F1). A análise conjunta de variância para produção de espigas mostrou efeitos significativos (P <0.01) para as capacidades geral e especĂfica de combinação e para as interações com locais. Tais resultados indicam variabilidade originada de efeitos gĂŞnicos aditivos e nĂŁo-aditivos. As variedades CMS 04 e CMS 05 apresentaram, respectivamente, os maiores valores para efeitos de capacidade geral de combinação, 142,82 e 233,93, e mĂ©dia geral para peso de espigas de 4.528 kg/ha e 4.445 kg/ha, respectivamente. Os maiores efeitos para capacidade especĂfica de combinação corresponderam aos cruzamentos CMS 05 x CMS 28 com 462,28 e CMS 11 x CMS 28 com 392,87. Os valores percentuais de heterose em relação a mĂ©dia dos pais foram de 21,16% e 17,49%e em relação ao pai mais produtivo foram de 12,92% e 13,28%, para os dois hĂbridos intervarietais citados. A mĂ©dia de produção das variedades paternais (4.127 kg/ha) foi inferior Ă mĂ©dia dos seus quinze hĂbridos (4.433 kg/ha). A maior produção mĂ©dia, 5.026 kg/ha, resultou do cruzamento entre as variedades CMS 05 e CMS 28.The objective of this study was to estimate the general and specific combining ability effects and heterosis value for ear yield from e diallel cross among six varieties of maize (Zea mays L.) under breeding at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS) at Sete Lagoas, MG, Brazil. The treatments were: CMS 04, CMS 05, CMS 11, CMS 12, CMS 22, CMS 28 and their 15 possible F1 hybrids. The combined analysis showed general and specific effects to be highly significant (P < 0.01), as well as their interactions with locations. There is an indication of variability among varieties with the presence of additive and nonadditive gene effects. The varieties CMS 04 and CMS 05 presented the highest values for general combining ability effects, 142.82 and 233.93, and mean ear weights of 4.528 kg/ha and 4.445 kg/ha, respectively. The hybrids CMS 05 x CMS 28 and CMS 11 x CMS 28 presented the highest values for specific combining ability effects of 462.28 and 392.87, respectively. Heterosis percentual values related to parental mean were 21.16% and 17.49% and to the highest yialding parent were 12.92% and 13.28% for the hybrids CMS 05 x CMS 28 and CMS 11 x CMS 28, respectively. Mean yield of parentals (4.127 kg/ha) was lower tham mean yield of the 15 hybrids (4,433 kg/ha). The highest mean yield was 5.026 kg/ha for the hybrid CMS 05 x CMS 28
Excitation and decay of projectile-like fragments formed in dissipative peripheral collisions at intermediate energies
Projectile-like fragments (PLF:15<=Z<=46) formed in peripheral and
mid-peripheral collisions of 114Cd projectiles with 92Mo nuclei at E/A=50 MeV
have been detected at very forward angles, 2.1 deg.<=theta_lab<=4.2 deg.
Calorimetric analysis of the charged particles observed in coincidence with the
PLF reveals that the excitation of the primary PLF is strongly related to its
velocity damping. Furthermore, for a given V_PLF*, its excitation is not
related to its size, Z_PLF*. For the largest velocity damping, the excitation
energy attained is large, approximately commensurate with a system at the
limiting temperatureComment: 5 pages, 6 figure
Isotopic composition of fragments in multifragmentation of very large nuclear systems: effects of the chemical equilibrium
Studies on the isospin of fragments resulting from the disassembly of highly
excited large thermal-like nuclear emitting sources, formed in the ^{197}Au +
^{197}Au reaction at 35 MeV/nucleon beam energy, are presented. Two different
decay systems (the quasiprojectile formed in midperipheral reactions and the
unique source coming from the incomplete fusion of projectile and target in the
most central collisions) were considered; these emitting sources have the same
initial N/Z ratio and excitation energy (E^* ~= 5--6 MeV/nucleon), but
different size. Their charge yields and isotopic content of the fragments show
different distributions. It is observed that the neutron content of
intermediate mass fragments increases with the size of the source. These
evidences are consistent with chemical equilibrium reached in the systems. This
fact is confirmed by the analysis with the statistical multifragmentation
model.Comment: 9 pages, 4 ps figure
