Relações Comprimento-peso Da Ictiofauna De Um Sistema Costeiro Subtropical: Uma Ferramenta Para Estimativas De Biomassa E Modelagem De Ecossistemas

Aiming to analyse the growth pattern, to allow biomass estimates and consequently to subsidize the ecosystem modelling, the length-weight relationships (LWR) of 39 fish species from the Araçá Bay, a subtropical coastal area chosen as model for a holistic study comprising environmental, social and economic aspects have been estimated. The objective of this study was to provide LWR for the fishes from the area itself, accurately based on the life stages of fish populations present there. Particularly for Albula vulpes, Trachinotus carolinus, T. falcatus, Archosargus rhomboidalis and Kyphosus sectatrix these are the first records of LWR in Brazil. © 2016, Universidade Estadual de Campinas UNICAMP.

Semiquantitative interpretation of anticardiolipin and antiβ2glycoprotein I antibodies measured with various analytical platforms: communication from the ISTH SSC subcommittee on Lupus Anticoagulant/Antiphospholipid antibodies

Background Antiβ2glycoprotein I (aβ2GPI) and anticardiolipin (aCL) IgG/IgM show differences in positive/negative agreement and titers between solid phase platforms. Method specific semiquantitative categorization of titers could improve and harmonize the interpretation across platforms. Aim To evaluate the traditionally 40/80 units thresholds used for aCL and aβ2GPI for categorization into moderate/high positivity with different analytical systems, and to compare with alternative thresholds. Material and methods aCL and aβ2GPI thresholds were calculated for two automated systems (chemiluminescent immunoassay (CLIA) and multiplex flow immunoassay (MFI)) by ROC-curve analysis on 1108 patient samples, including patients with and without APS, and confirmed on a second population (n=279). Alternatively, regression analysis on diluted standard material was applied to identify thresholds. Thresholds were compared to 40/80 threshold measured by an enzyme linked immunosorbent assay (ELISA). Additionally, likelihood ratios (LR) were calculated. Results Threshold levels of 40/80 units show poor agreement between ELISA and automated platforms for classification into low/moderate/high positivity, especially for aCL/aβ2GPI IgG. Agreement for semiquantitative interpretation of aPL IgG between ELISA and CLIA/MFI improves with alternative thresholds. LR for aPL IgG increase for thrombotic and obstetric APS based on 40/80 thresholds for ELISA and adapted thresholds for the other systems, but not for IgM. Conclusion Use of 40/80 units as medium/high thresholds is acceptable for aCL/aβ2GPI IgG ELISA, but not for CLIA and MFI. Alternative semiquantitative thresholds for non-ELISA platforms can be determined by a clinical approach or by using monoclonal antibodies. Semiquantitative reporting of aPL IgM has less impact on increasing probability for APS

Three-Dimensional Integrable Models and Associated Tangle Invariants

In this paper we show that the Boltzmann weights of the three-dimensional Baxter-Bazhanov model give representations of the braid group, if some suitable spectral limits are taken. In the trigonometric case we classify all possible spectral limits which produce braid group representations. Furthermore we prove that for some of them we get cyclotomic invariants of links and for others we obtain tangle invariants generalizing the cyclotomic ones.Comment: Number of pages: 21, Latex fil

Phenolic compound profile by UPLC-MS/MS and encapsulation with chitosan of Spondias mombin L. fruit peel extract from Cerrado hotspot-Brazil

8openInternationalInternational coauthor/editorTaperebá (Spondias mombin L.) is a native species of the Brazilian Cerrado that has shown important characteristics such as a significant phenolic compound content and biological activities. The present study aimed to characterize the phenolic compound profile and antioxidant activity in taperebá peel extract, as well as microencapsulating the extract with chitosan and evaluating the stability of the microparticles. The evaluation of the profile of phenolic compounds was carried out by UPLC-MS/MS. The in vitro antioxidant activity was evaluated by DPPH and ABTS methods. The microparticles were obtained by spray drying and were submitted to a stability study under different temperatures. In general, the results showed a significant content of polyphenols and antioxidant activity. The results of UPLC-MS/MS demonstrated a significant content of polyphenols in taperebá peel, highlighting the high content of ellagic acid and quercetin compounds. There was significant retention of phenolic compounds when microencapsulated, demonstrating high retention at all evaluated temperatures. This study is the first to microencapsulate the extract of taperebá peel, in addition to identifying and quantifying some compounds in this fruitopenBrito, Giovanna Oliveira de; Reis, Bruna Cabral; Ferreira, Eduardo A; Vilela Junqueira, Nilton T; Sá-Barreto, Lívia C L; Mattivi, Fulvio; Vrhovsek, Urska; Gris, Eliana FortesBrito, G.O.D.; Reis, B.C.; Ferreira, E.A.; Vilela Junqueira, N.T.; Sá-Barreto, L.C.L.; Mattivi, F.; Vrhovsek, U.; Gris, E.F

Assessment of oxidative metabolism

Oxidative metabolism is one of the central physiological processes that regulate multiple functions in a cell including cell death and survival, proliferation, gene transcription, and protein modification. There are multitudes of techniques that are used to evaluate oxidative activity. Here, we summarize how to measure oxidative activity by flow cytometry. This versatile technique allows the evaluation of the level of oxidative activity within heterogeneous populations of cells and in cell culture. Flow cytometry is a quick method that yields highly reproducible results with small sample volumes. Therefore, it is an ideal technique for evaluating changes in oxidative activity in samples from mice

Caracterização de duas cultivares de soja RR para cultivo no Sul de Minas Gerais.

Avaliou-se duas cultivares de soja transgênicas RR (BRSMG 780RR e BRSMG 820RR) oriundas do Programa de Melhoramento Genético de Soja para o estado de Minas Gerais, convênio Embrapa/Epamig/Fundação Triângulo, submetidas à quatro populações de plantas (100.000, 200.000, 300.000 e 400.000 plantas ha-1). Utilizou se o delineamento de blocos casualizados com três repetições, determinando-se altura de plantas e de inserção de 1° legume, índice de acamamento, n° de legumes por planta, n° de grãos por legume, peso de 100 grãos e rendimento de grãos. As cultivares BRSMG 780RR e BRSMG 820RR mostraram alta plasticidade à medida que a variação na população de plantas alterou somente os índices de acamamento de plantas. No entanto, recomenda-se estudos por mais de um ano agrícola
