Resumo Seis diferentes cultivares de feijão comum (BRS Embaixador, BRS Pitanga, BRS Estilo, Pérola, BRS Campeiro e BRS Esplendor) foram caracterizados visando suas possíveis utilizações em produtos alimentícios variados. As amostras foram analisadas para determinação da composição química, peso de 100 grãos, pH, capacidade de absorção de água e óleo (CAA e CAO, respectivamente), propriedades espumantes nos pHs 2,5; 5,6; e 8,0 e propriedades emulsificantes. A relação entre as propriedades físico-químicas e funcionais foi descrita utilizando Análise de Componentes Principais (ACP). Os resultados da composição química, peso de 100 grãos, CAA e CAO mostraram diferenças até mesmo entre cultivares do mesmo grupo comercial. A capacidade de formação de espuma também variou entre os cultivares. A capacidade de formação de espuma e a estabilidade da espuma foram maiores nos pHs 5,6 e 8,0. A capacidade emulsificante foi alta para todos os cultivares bem como a estabilidade da emulsão. De acordo com estas propriedades, com a contribuição da ACP, cada cultivar diferente de feijão pode ser destinado a aplicações específicas, de acordo com as suas propriedades físico-químicas.

Abstract Six different common bean cultivars (BRS Embaixador, BRS Pitanga, BRS Estilo, Pérola, BRS Campeiro and BRS Esplendor) were characterized aiming to determine possible uses for them in various food products. The samples were analysed to determine their chemical composition, weight per hundred beans, pH, water and oil absorption capacities (WAC and OAC, respectively), foaming at pH 2.5, 5.6 and 8.0 and emulsifying properties. The relationship between the physicochemical and functional properties was described using the Principal Component Analysis (PCA). The results of the chemical composition, weight per hundred beans, WAC and OAC showed differences even between cultivars of the same commercial group. Foaming also varied between the cultivars and foaming capacity and stability were greatest at pH 5.6 and 8.0. The emulsifying capacity proved quite high for all cultivars, as well as the stability of the emulsion. According to these properties, with the contribution of the PCA, each different bean cultivar can be destined to specific applications according to its physicochemical properties.

Visando avaliar os efeitos cardiovasculares e analgésicos de dois protocolos epidurais em felinos submetidos à OSH, 16 gatas mestiças, adultas, que, após indução à anestesia geral, receberam anestesia epidural (L7 - S1) com 0,26mL kg-1 de ropivacaína 0,75%, isolada (GR) ou associada a 0,1mg kg-1 morfina (GRM). A ETCO2, f, FC, PAS, T°R e relaxamento muscular foram avaliados no momento basal, 30 minutos após epidural, após incisão de pele, ligadura dos pedículos ovarianos e cérvix, final da celiorrafia e cirurgia, sendo administrado fentanil, caso ocorresse aumento de 20% na PAS, FC ou f em relação ao momento basal. Ao final do procedimento, foram avaliados, com auxílio de uma escala multidimensional de dor aguda em felinos, durante 12 horas, e, quando a pontuação fosse ≥8, era realizado resgate analgésico com morfina 0,2mg kg-1. Não ocorreram diferenças entre ETCO2, f, T°C e relaxamento muscular. A PAS aumentou em ambos os grupos durante o pinçamento dos pedículos ovarianos e cérvix, quando 100% dos animais do GR e 87,5% do GRM necessitaram fentanil transoperatório. Em 100% dos animais do GR, houve necessidade de morfina pós-operatória às 2 e 4 horas de avaliação, comparados com 50% e 37,5% no GRM. Nos momentos seguintes aos resgates, o somatório de pontos foi semelhante entre grupos. Conclui-se que a administração epidural de ropivacaína associada à morfina em gatas submetidas à ovariosalpingohisterectomia reduz o requerimento analgésico pós-operatório em até 56,2%, durante as primeiras 4 horas, e promove analgesia adequada durante 12 horas, quando comparado à ropivacaína isolada

Seeking to evaluate the cardiovascular and analgesic effects of two epidural protocols in cats undergoing OH, 16 female adult mixed-breed cats were induced to general anesthesia, and then epidural was achieved with 0,26mL kg-1 of isolated ropivacaine (GR) (0,75%) or associated with 0,1mg kg-1 morphine (GRM). ETCO2, RR, HR, SAP, T° and muscular relaxation were evaluated in baseline, 30 minutes after epidural; after skin incision, ovarian pedicles and uterine cervix ligation; end of laparohraphy; and end of surgery. They received fentanyl if SAP, HR or f, rise in 20% of baseline. At the end of OH, a multidimensional pain scale for cats was used during 12 hours, and rescued with morphine 0,2mg kg-1, when the scale score was ≥8 points. There were no differences in ETCO2, RR, T°C and muscular relaxation. SAP increased in both groups during the ovarian pedicle and cervix clamping. In 100% of the animals in GR and 87.5% of the GRM, it was necessary fentanyl during surgery. In 100% of GR animals was required analgesic rescue with morphine at 2 and 4 hours of postoperative evaluation, compared with 50% and 37,5% in GRM, where after the analgesic rescue, in the next hours, the sum of points was similar between groups. It was concluded that epidural administration of morphine and ropivacaine in cats submitted to OH, reduces post operatory analgesic requirements to 56,2% during the first four hours, and promote adequate analgesia for 12 hours in cats submitted to OH, when compared to ropivacaine alone

Within the country of Brazil, Santa Catarina is a major shellfish producer. Detection of viral contamination is an important step to ensure production quality and consumer safety during this process. In this study, we used a depuration system and ultraviolet (UV) disinfection to eliminate viral pathogens from artificially infected oysters and analysed the results. Specifically, the oysters were contaminated with hepatitis A virus (HAV) or human adenovirus type 5 (HAdV5). After viral infection, the oysters were placed into a depuration tank and harvested after 48, 72 and 96 h. After sampling, various oyster tissues were dissected and homogenised and the viruses were eluted with alkaline conditions and precipitated with polyethylene glycol. The oyster samples were evaluated by cell culture methods, as well as polymerase chain reaction (PCR) and quantitative-PCR. Moreover, at the end of the depuration period, the disinfected seawater was collected and analysed by PCR. The molecular assays showed that the HAdV5 genome was present in all of the depuration time samples, while the HAV genome was undetectable after 72 h of depuration. However, viral viability tests (integrated cell culture-PCR and immunofluorescence assay) indicated that both viruses were inactivated with 96 h of seawater recirculation. In conclusion, after 96 h of UV treatment, the depuration system studied in this work purified oysters that were artificially contaminated with HAdV5 and HAV.
