Published: July 2019

Показана актуальность разработки точных систем управления процессом ионно-плазменной очистки инструмента. Важным критерием качества программного управления при очистке является поддержание температуры очищаемого инструмента в соответствии с заданной временной программой при недопустимости перегрева в радиальном направлении. Максимальное допускаемое отклонение температуры от заданной линейной программы нагрева составляет ±25 K. В статье исследуется проблема распределения температурного поля при нагреве металлорежущего инструмента цилиндрической формы для ранее разработанной системыавтоматического управления температурным режимом ионно-плазменной установки Булат. В установке нагрев инструмента производится как за счет потоков тепла ионной бомбардировки, так и от нагретой подложки, а потери тепла происходят в результате излучения. Тепловой поток излучения определяется законом Стефана-Больцмана. Теплопередача от нагретой подложки к инструменту определяется законом Фурье. Для анализа качества работы системы управления было проведено прецизионное моделирование технологического процесса с использованием математического аппарата дифференциальных уравнений в частных производных. В процессе решения классического уравнения теплопроводности инструмента используются функции Бесселя 1-го рода 0-го и 1-го порядков. Особенностью моделирования является замена граничных условий импульсным управлением в соответствии с теорией синтеза распределенных систем управления. Анализ показал, что разработанная система управления практически одинаково поддерживает температуру по всему радиусу стержня, что показывает высокое качество её функционирования.

ABSTRACT Objective To investigate the expressions of plasma cystatin C (Cys-C), D-dimer (D-D) and hypersensitive C-reactive protein (hs-CRP) in patients with intracranial progressive hemorrhagic injury (IPHI) after craniocerebral injury, and their clinical significance. Methods Forty-two IPHI patients and 20 healthy participants (control) were enrolled. The severity and outcome of IPHI were determined according to the Glasgow Coma Scale and Glasgow Outcome Scale, and the plasma Cys-C, hs-CRP and D-D levels were measured. Results The plasma Cys-C, D-D and hs-CRP levels in the IPHI group were significantly higher than those in the control group (p < 0.01). There were significant differences of plasma Cys-C, D-D and hs-CRP levels among different IPHI patients according to the Glasgow Coma Scale and according to the Glasgow Outcome Scale (all p < 0.05). In the IPHI patients, the plasma Cys-C, D-D and hs-CRP levels were positively correlated with each other (p < 0.001). Conclusion The increase of plasma Cys-C, D-D and hs-CRP levels may be involved in IPHI after craniocerebral injury. The early detection of these indexes may help to understand the severity and outcome of IPHI.

ABSTRACT Low- and middle-income countries face tight health care budgets, not only new resources, but also costly therapeutic resources for treatment of ischemic stroke (IS). However, few prospective data about stroke costs including cerebral reperfusion from low- and middle-income countries are available. Objective To measure the costs of stroke care in a public hospital in Joinville, Brazil. Methods We prospectively assessed all medical and nonmedical costs of inpatients admitted with a diagnosis of any stroke or transient ischemic attack over one year, analyzed costs per type of stroke and treatment, length of stay (LOS) and compared hospital costs with government reimbursement. Results We evaluated 274 patients. The total cost for the year was US$1,307,114; the government reimbursed the hospital US$1,095,118. We found a significant linear correlation between LOS and costs (r = 0.71). The median cost of 134 IS inpatients who did not undergo cerebral reperfusion (National Institutes of Health Stroke Scale [NIHSS] median = 3 ) was US$2,803; for IS patients who underwent intravenous (IV) alteplase (NIHSS 10), the median was US$5,099, and for IS patients who underwent IV plus an intra-arterial (IA) thrombectomy (NIHSS > 10), the median cost was US$10,997. The median costs of a primary intracerebral hemorrhage, subarachnoid hemorrhage, and transient ischemic attack were US$2,436, US$8,031 and US$2,677, respectively. Conclusions Reperfusion treatments were two-to-four times more expensive than conservative treatment. A cost-effectiveness study of the IS treatment option is necessary.

Background Although classical human T-cell lymphocyte virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis syndrome is the most frequent HTLV-1-associated neurological disorder, some “minor” neurological disorders can be seen in “asymptomatic” carriers. These disorders, including cognitive alterations already described in clinical cases and studies, may constitute an intermediate syndrome (IMS) between the asymptomatic state and myelopathy. The aim of this study was to investigate the presence of cognitive deficits in patients with HTLV-1 virus, who usually are diagnosed as asymptomatic. Methods A total of 54 HTLV-1-infected patients were evaluated, 35 asymptomatic and 19 with minor neurological alterations (evaluated by a neurologist); 25 HTLV-1-seronegative individuals served as controls. The instruments used were: Beck’s Depression Inventory, Lawton’s Daily Life Activity Scale, and a complete neuropsychological battery. The application of these evaluation instruments was performed blindly, with the evaluator neuropsychologist not knowing the clinical condition of the patient. Results Most of the participants in this cohort, including seronegative controls, were female (n = 57, 72.21%), their mean age was 52.34 years (SD = 14.29) and their average schooling was 9.70 years (SD = 4.11). Discussion Participants classified with IMS had lower gross scores when compared with both the patients classified as asymptomatic and with the control group, and when tested for auditory episodic memory of immediate (p < 0.01), and late (p = 0.01), recall. Conclusion Patients with IMS presented with memory impairment when compared with asymptomatic patients and seronegative individuals; this is one of the symptoms that aids in the classification of the syndrome.

ABSTRACT Objective To analyze the risk factors and prognosis related to early post-traumatic epilepsy (EPTE). Methods One hundred and eighty-six patients with traumatic brain injury were enrolled. Their full clinical data were collected. Single factor analysis and logistic regression analysis of risk factors related to EPTE were performed. The prognosis of patients was determined. Results Single factor analysis showed that there were significant differences of age (p = 0.011), epilepsy history (p < 0.001), injury site (p = 0.004), injury type (p < 0.001) and injury degree (p < 0.001) between the EPTE group (40 patients) and non-EPTE group (146 patients). Logistic regression analysis showed that the injury site, injury type and injury degree were the main risk factors for EPTE. The odds ratio values of injury site, injury type and injury degree were 1.977 (1.473–2.679), 2.096 (1.543–2.842) and 2.376 (1.864–3.609), respectively. The logistic regression equation was P = Exp (-1.473 + 0.698 × injury site + 0.717 × injury type + 0.935 × injury degree). The sensitivity and specificity of injury site, injury type and injury degree for predicting EPTE were 79.2% and 80.5%, 78.9% and 85.7% and 84.2% and 81.0%, respectively. The analysis of prognosis showed that the Glasgow Outcome Scale/Activity of Daily Living Scale scores in the EPTE group were significantly lower than those in non-EPTE group (p < 0.05). Conclusions Injury site, injury type and injury degree are the main risk factors for EPTE. The prognosis of patients with traumatic brain injury can be affected by EPTE.

Abstract Objective: To assess the impact of magnetic resonance imaging (MRI) on the locoregional staging of breast cancer. Materials and Methods: We evaluated 61 patients with breast cancer who underwent pre-treatment breast MRI, between August 2015 and April 2016. An experienced breast surgeon determined the surgical treatment, on the basis of the findings of conventional imaging examinations, and made a subsequent treatment recommendation based on the MRI findings, then determining whether the MRI changed the approach, as well as whether it had a positive or negative impact on the treatment. Results: The mean age was 50.8 years (standard deviation, 12.0 years). The most common histological type was invasive breast carcinoma of no special type (in 68.9%), and the most common molecular subtype was luminal B (in 45.9%). Breast MRI modified the therapeutic management in 23.0% of the cases evaluated, having a positive impact in 82.7%. Conclusion: Breast MRI is an useful tool for the locoregional staging of breast cancer, because it provides useful information that can have a positive impact on patient treatment.

Published: July 2019

Resumo: Para ampliar a compreensão das problemáticas ambientais atuais, este texto reúne as análises interpretativas de dois documentos, os quais, por possuírem perspectivas distintas, contribuem significativamente com o estudo da teoria fleckiana. São dois coletivos de pensamento desenvolvendo práticas científicas com intencionalidades advindas das opções teóricas e políticas, configurando um processo dinâmico de produção de conhecimento. A essência de cada um desses coletivos de pensamento consiste na ampliação e na disseminação da ideia transpessoal, por ela não pertencer, de forma exclusiva, a nenhum dos componentes do coletivo. Propiciar a troca constante de concepções interna e externamente impulsiona o conhecimento científico, cuja evolução depende do processo coletivo em que o pensamento se desenvolve por vínculos e interferências engendradas pelo condicionamento social.

Authors: Moura Jr. James Ferreira , Sarriera Jorge Castellá
Published: July 2019

Resumo O objetivo deste trabalho é analisar o impacto de diferentes formas de mensuração da pobreza nas variações do Índice de Bem-Estar Pessoal (BEP) de indivíduos pobres e não pobres. Foram realizadas análises comparativas com o teste t de Student e Análise Multivariada de Variância (MANOVA), em uma perspectiva comparativa de diferentes formas de mensuração da pobreza com 731 pessoas, provenientes de um estado do Nordeste (57%) e do Sul (43%) do Brasil, com idade média de 36,68 anos (DP = 16,02). Utilizaram-se medidas monetárias e multidimensionais da pobreza. Identifica-se que, independente da forma de mensuração da pobreza, há um impacto negativo no BEP. Porém, observa-se que a utilização da perspectiva multidimensional tem uma maior capacidade de identificação dos impactos psicossociais da pobreza.

Published: July 2019

Abstract At the School of Veterinary Medicine and Animal Science, University of São Paulo, Brazil, preliminary surgical training involving live animals has been replaced by the use of embalmed canine cadavers. This study aimed to improve the embalming technique based on the modified Larssen solution by altering the original formulation. Twenty-four canine corpses obtained according to the norms and resolutions described by the animal research ethics committee were used in this study. The cadavers were randomly allocated to two groups, G1 and G2, and treated with modified Larsen solution containing 20% and 10% formalin, respectively. The Larssen solution used in G1 contained a higher volume of distilled water and higher formalin concentration than the one used in G2. Cadavers were used in hands-on surgical training labs for four weeks. The following evaluation criteria were considered: general appearance, muscle tissue color, tissue texture/consistency, joint flexibility, odor development, and skin integrity in the abdominal and other regions involved in surgical training. The cadavers in both groups showed good general appearance and retained satisfactory organoleptic properties for surgical training throughout the experimental period. There was no significant difference between the groups treated with 20% or 10% modified Larssen solution (p > 0.05; chi-square test). The present findings were considered positive, because the dilution of the original formulation exhibited similar efficacy and required smaller amounts of chemicals, thus reducing the formulation cost.

Published: July 2019

Abstract: In order to inventory the species richness and fish fauna composition along the Ivinhema river basin, 232 stretches of rivers and streams were sampled from 2000 to 2018, using a rectangular sieve, trawls, gillnets, cast nets, and electrofishing. A total of 141 species was caught in the basin, including seven orders and 35 families. For the recorded species, 42 are from the upper Paraná river, 51 from lower Paraná river, 27 from other basins, two from other continents, and the origin for 19 species are unknown/not reported. Six species are registred for the first time in the upper Paraná river basin: Astyanax abramis, Moenkhausia oligolepis, Serrapinnus kriegi, Curimatopsis myersi, Pyxiloricaria menezesi, and Cichlasoma dimerus. This is the first complete survey of the ichthyofauna in lotic environments along the whole Ivinhema river basin, containing relevant information for comparing studies and serving as reference data that can contribute to the management and implementation of politics for conservation of the basin. This survey also increases 24 species on the list of the most complete inventory in the upper Paraná river published in 2007.

Authors: Bellegard Gabriela M.C. , Lopes Érika R. , Bisetto Shayne P. , Hage Maria Cristina F.N.S.
Published: July 2019

ABSTRACT: The elbow is a complex joint and has great clinical relevance in small animal medicine. Previous research in this area has been performed using radiographic and tomographic methods; however, there are limited studies on ultrasonography. The aims of this study was suggesting an evaluation protocol for elbow scan and describe the ultrasonographic anatomy of the elbow joint in dogs. Ten cross-breed dogs weighing 5-15kg underwent radiography and were selected for this ultrasonographic study. The protocol was established for the ultrasonographic description dividing the articular areas in the proximal, middle, and distal, lateral, cranial, medial, and caudal faces. The approach was performed in the longitudinal, transverse and oblique planes and the musculoskeletal structures were described according to the architecture, echogenicity and echotexture. Computed tomography and magnetic resonance imaging scans were obtained for one animal for comparison. Ultrasonography was effective in visualizing and analyzing muscles, tendons and ligaments. Bone contours and regions that have clinical significance such as the medial coronoid process and anconeus process were identified, but with limited access. Prior knowledge of the normal sonographic anatomy of the elbow joint, as well as its technical advantages and limitations will allow further studies related to the identification of musculoskeletal disorders.
Investigation of Norovirus genogroups (GI, GII and GIV) in stool of pet dogs with diarrhea
Authors: Sokel Sevinc , Kale Mehmet
Published: July 2019

ABSTRACT: In this study, we searched the existence of human norovirus (NoV) GI, GII and GIV in the stool of 128 pet dogs with diarrhea, of different sex, age and breed, in Burdur, Turkey, using Real-Time PCR method. Human NoV GII was found in only 5 of the 128 dog stool samples (3.91%). It was discovered that human NoV existed most in crossbreed, female and aged 24 months or over dogs. These dogs found with human NoV GII were either bought from pet shops, stray dogs or taken as puppy of another pet dog. The sheltering conditions of these dogs were moderate and they were fed with home food residue and dry food. It was also found that most of them were vaccinated and had certain walking sites. The owners of the animals detected with infection generally did not have the habit of washing their hands or changing their clothes before or after caring their pets. We strongly advice that dog owners’ personal hygiene, the necessity of changing their clothes during their contact with animals, the environment provided for the dog, the sensitivity in caring, use of strong and effective disinfectant, keeping the dogs away from toilets and sewerage systems, as well as not feeding them with food residues are crucial issues in dogs’ care. Owners of the dogs with NoV GII were middle aged or elderly people, male, and there were no children in their houses. As these dogs are treated like the owner’s child, it is assumed that they could be transmitted with NoV GII as a result of close interaction with their owner.

Published: July 2019

Resumo Os estudos no âmbito da mediação da informação são frequentemente vinculados à Biblioteconomia e raramente referem-se ao campo da Arquivologia. O objetivo deste artigo é investigar como está o panorama da mediação da informação na Arquivologia, a partir da produção científi ca na Ciência da Informação. Como metodologia, apresenta inicialmente uma revisão de literatura sobre a temática e aplica uma pesquisa bibliográfi ca nos periódicos da área de Comunicação e Informação com Qualis entre A1 e B1, a partir de seus números publicados até o ano de 2017 e anais das dezoito edições do Encontro Nacional de Pesquisa em Ciência da Informação (1994-2017). Dessa forma, foram localizados 11 textos, sendo seis trabalhos do Encontro e cinco artigos de periódicos. A análise apresenta as tendências de discussão presentes nos textos recuperados, as seis categorias estabelecidas, os autores mais produtivos e mais citados, a rede de citação existente, as palavras-chave empregadas e os procedimentos metodológicos adotados. Conclui que, em sua maioria, o discurso que transparece nos textos analisados aproxima-se mais da concepção de difusão/disseminação do que da mediação. De outro lado, porém, é esta última que evidencia o arquivista como um sujeito que interfere ativamente na construção de saberes dos usuários e que reconhece seus interesses como foco do trabalho.
Pessoas, manatins e o ambiente aquático na América moderna: confluência e divergência nas interações históricas entre humanos e animais
Authors: Brito Cristina
Published: July 2019

RESUMO Com uma distribuição geográfica histórica alargada em zonas costeiras, ambientes de transição e fluviais do Oceano Atlântico tropical, o manatim (manati das Índias Ocidentais, peixe-boi ou iguaragua do Brasil colonial) era bastante valorizado. As fontes documentais e iconográficas dos séculos XVI e XVII mostram-nos que era usado como alimento, para fins medicinais, para produzir utensílios ou como animal de estimação, mas seu valor económico e simbólico foi igualmente dominante. A sobre-exploração contínua conduziu ao desaparecimento de muitas populações de manatins, os quais hoje enfrentam o risco de extinção. Pretendemos explorar do ponto de vista da história ambiental marinha o significado pragmático e simbólico dos manatins numa ligação próxima aos valores atribuídos aos rios e cursos de água. Esperamos também contribuir para colocar manatins e o seu ecossistema no centro de uma discussão sobre contextos e interações ambientais e socioculturais das sociedades indígenas e coloniais nas Américas do período moderno.

Resumo No presente trabalho são analisados os determinantes da utilização de assistência técnica pelos agricultores familiares brasileiros em 2014. Utilizando dados da Pesquisa Nacional por Amostras Domiciliares (PNAD) de 2014, foi estimado um modelo de regressão qualitativa probit, permitindo a identificação da magnitude e significância do efeito de cada variável explicativa sobre a probabilidade de utilização de assistência técnica no último trabalho agrícola desenvolvido no empreendimento. Os resultados evidenciam que o perfil socioeconômico, as características produtivas e a localização do agricultor familiar afetam significativamente a probabilidade de utilização da assistência técnica. Observou-se que o fato de um indivíduo possuir pele não branca, ter como principal canal de comercialização a venda direta ao consumidor, ser cessionário ou apresentar condição não especificada em relação à terra, possuir idade avançada ou baixa escolaridade ou renda per capita apresentam efeito estatisticamente significativo de redução na probabilidade de utilização da assistência técnica. Por outro lado, o fato de o indivíduo ter como principal canal de comercialização a venda para empresas ou cooperativas, de possuir empregados temporários ou estar localizado na região Sul aumentam essa probabilidade. Conclui-se, por fim, que estudos aprofundados para o melhor entendimento desses efeitos podem fornecer respaldo para o aperfeiçoamento das ações de assistência técnica.

Published: July 2019

RESUMO A avaliação do movimento é importante e necessária para identificar os riscos de lesão possibilitando a elaboração de programas de exercícios preventivos e corretivos, visando a melhora do desempenho das atividades funcionais e o consequente bem-estar. O objetivo deste estudo foi analisar e comparar a incidência do valgo dinâmico do joelho em mulheres praticantes de musculação e mulheres sedentárias, e identificar os sintomas álgicos e o potencial de lesão associados a essa alteração biomecânica. Sessenta mulheres foram divididas em dois grupos: praticantes de musculação e sedentárias, com idade entre 18 e 30 anos. Os dados foram coletados utilizando-se o sistema Functional Movement Screen e foram submetidos a análises estatísticas descritiva e inferencial. O valgo dinâmico do joelho é apresentado por 60% das mulheres sedentárias, quando comparadas às mulheres praticantes de musculação (33,3%), demonstrando associação entre o valgo dinâmico e o sedentarismo (p<0,03). Não houve associação entre a dor e o valgo dinâmico do joelho (p>0,06) para ambos os grupos. Das mulheres sedentárias, 50,0% apresentaram escore FMS abaixo de seis pontos, representando alto risco de lesão. Conclui-se que mulheres sedentárias apresentam maior predisposição ao valgismo dinâmico do joelho, maior sintomatologia dolorosa e maior risco de lesão nos membros inferiores.

Published: July 2019

ABSTRACT Objective: to understand the nursing practices related to peripheral venous catheter and to identify deviations related to the scientific evidence regarding the prevention of phlebitis. Method: qualitative study with data collection by means of participant observation techniques and semi-structured interviews, with 26 and 15 nurses, respectively, from a Portuguese hospital. Data content analysis was performed. Results: In the category “nursing actions”, nursing practices related to: selection of catheter insertion site and its caliber size, evaluation of insertion site for signs of inflammation, insertion site dressing, disinfection of accessories, hand hygiene and patient participation in care emerged. There were situations of deviations in these practices in relation to scientific evidence. Conclusion: Nursing practices presented deviations in relation to scientific evidence, and were influenced by the size of the institution, patient characteristics, and lack of knowledge of nurses regarding certain actions that pose a risk to patient safety. The creation of protocols and the implementation of continuous education are fundamental for the acquisition of competencies by nurses, for correcting deviations and providing a safe quality nursing care to the patient.

ABSTRACT Objective: to identify reiteration trends or overcoming of gender inequalities in reports on female athletes published in Brazilian newspapers. Method: a documentary research based on reports published in the special report on Rio 2016 Olympic Games in two Brazilian newspapers of national circulation. 51 articles and 87 images were selected and submitted to thematic content analysis and processed in webQDA software. Results: four categories emerged from the empirical data: women’s representativeness in the Olympic Games; women on the champions platform; recognition of women from overcoming male performance; and violence against women gaining ground in sports’ agenda. Media coverage replicated socially constructed sexist patterns by portraying athletes from stereotyped female characteristics and revealed gender inequalities in describing situations of violence against athletes perpetrated by members of technical teams and supporters. Conclusion: despite the visibility given to the protagonism of athletes, there was the production and reproduction of gender stereotypes. Therefore, it is necessary to deconstruct and confront inequalities between men and women.

Abstract Introduction: Obesity is a contributing factor to the development of urinary incontinence (UI). Objective: The objective of this study was to evaluate the prevalence of UI symptoms in women with morbid obesity and their impacts on quality of life (QOL), correlating the influence of age and body mass index (BMI) with the presence of UI. Method: Sixty-five women undergoing preoperative bariatric surgery, aged 35.8 ± 9.97 years, with an average BMI of 45.04 ± 6.79 kg/m2 were asked about the presence of UI symptoms; when they answered positively, the King’s Health Questionnaire (validated into Portuguese) was applied. The questionnaire was self-administered and all answers were assigned numerical scores. These scores were distributed according to quartiles and correlated with age and BMI. The level of hypothesis rejection was 5%, and analyses were performed using BioEstat software version 5.3. Results: Among 65 interviewees, 19 (29.23%) had symptoms of UI and went on to answer the questionnaire. The highest-scoring areas were “incontinence impact” (36.8) and “general health perception” (32.9). There was no significant correlation between questionnaire scores and BMI. In the association with age, the “incontinence impact” domain showed a significant, positive and moderate correlation (r = 0.52; p = 0.02). Conclusion: The prevalence of UI symptoms in the sample had a slight negative effect on QOL; however, UI associated with older ages significantly affected the QOL of the studied volunteers.

O estudo foi realizado na Coordenação Geral de Gestão da Atenção Básica, do Departamento de Atenção Básica do Ministério da Saúde. Configura uma pesquisa ancorada na epistemologia qualitativa, com a realização de pesquisa documental, observação, entrevistas em profundidade e grupos focais entre novembro de 2015 e junho de 2017. Os resultados permitiram a identificação de dois elementos estruturantes do trabalho dos apoiadores - vínculo e conhecimento do território -, os quais subsidiaram a construção de uma tipologia da estratégia de atuação desenvolvida e operada pelos apoiadores, a saber: aplicação, adaptação e cooperação. Conclui-se que o avanço da implantação da estratégia de apoio institucional foi possível fundamentalmente em função da dinâmica relacional e presencial entre sujeitos, e seus resultados indicam possibilidades concretas de avanço na garantia do direito à saúde, não obstante as dificuldades e contradições que caracterizam o federalismo brasileiro.

Resumo O estudo que originou este artigo, realizado entre 2015 e 2017, busca a compreensão de possíveis relações no âmbito produtivo, ambiental e sanitário na cidade de Goiana, Pernambuco, diante da chegada do empreendimento multinacional da Fiat Chrysler Automobiles. Objetivou-se construir uma matriz explicativa com base no framework força motriz-pressão-situação-exposição-efeito-ação com sistematização de indicadores para o monitoramento de mudanças no território que possam afetar a saúde da população local e o ambiente decorrentes da instalação do complexo automotivo. Para tal, foram propostos componentes descritivos para cada dimensão da matriz e realizada sistematização de dados secundários em diferentes bancos de dados. Houve apreensão de efeitos ao bem viver no contexto local resultantes da exposição territorial ao aumento da violência, precarização e agravos relacionados ao trabalho, contaminação ambiental e saneamento básico precário. São propostas ações para o enfrentamento de problemas complexos e sistêmicos identificados, as quais podem subsidiar estratégias para a vigilância em saúde ambiental e em saúde do trabalhador. Por meio do framework, podemos traçar processos de vulnerabilização no território local associando-os a forças estruturantes produtivas e a modificações na situação da reprodução social.

ABSTRACT A new species of whiptail armored catfish belonging to the genus Pseudohemiodon is described. The new species inhabits aquatic systems of the Orinoco River basin, mostly in the Llanos region of Colombia and Venezuela. Previously, it had identified as P. laticeps erroneously. The genus Pseudohemiodon includes seven known species inhabit Amazon and Paraná-Paraguay-Uruguay rivers basins. The new species is distinguished from congeners by the combination of the following characters: abdomen totally covered; area in front of gill opening without plates, ventrally; dorsal body color pattern without transversal dark bands, mostly in the caudal peduncle; head with straight sides; head and caudal peduncle narrower.

ABSTRACT A field study of the sex ratio, length-weight ratio, body size at first gonadal maturation, and the breeding season of the red-tailed catfish, Phractocephalus hemioliopterus, was carried out in the region of the middle Xingu River in the eastern Amazon basin. The fish were sampled quarterly from September 2012 to January 2014 using gillnets and long lines. The sex ratio was balanced, and while males and females were similar in standard length, the females were heavier than the males, on average. The males presented negative allometric growth, and the females, isometric growth. The estimated size at first maturity was 77.8 cm. The variation in the gonadosomatic index and the greater frequencies of mature specimens indicated a reproductive peak at the beginning of the high-water (flood) period. As P. hemioliopterus is an important commercial fish, our findings will contribute to the future development of effective conservation and management strategies, such as minimum catch size and a close season that is appropriate for the region. These data will also provide important insights for the evaluation of potential impacts on the biology of this fish resulting from the construction of Belo Monte dam.

ABSTRACT The objective of this work was to evaluate the contact toxicity of essential oil of Croton pulegiodorus Baill on six populations of Sitophilus zeamais Motschulsky. The S. zeamais populations used were from Crixás-GO, Espírito Santo do Pinhal-SP, Juiz de Fora-MG, Picos-PI, Serra Talhada-PE, and Vicentina-MS, Brazil, and present different susceptibility to synthetic insecticides. The essential oil of C. pulegiodorus used was obtained from plants collected in Triunfo-PE, Brazil. The lethal concentrations (LC50 and LC90), toxicity ratio of the essential oil, and the resistance ratio of the populations were estimated. The S. zeamais population from Serra Talhada-PE presented the lowest LC50 (4.21 μL 20 g-1) and LC90 (6.67 μL 20 g-1) and was the reference for susceptibility to the essential oil of C. pulegiodorus. The S. zeamais population from Espírito Santo do Pinhal-SP presented the highest LC50 (6.02 μL 20 g-1) and LC90 (10.55 μL 20 g-1) and was the reference for tolerance to the essential oil of C. pulegiodorus. The toxicity ratio ranged from 1.01 (Picos-PI) to 1.43 (Serra Talhada-PE); and the resistance ratio ranged from 1.13 (Crixás-GO) to 1.43 (Espírito Santo do Pinhal-SP). The essential oil of C. pulegiodorus reduced the emergence of adult S. zemais and showed residual effect, with contact toxicity, after 30 and 60 days of application.

ABSTRACT The aim of the present study was to evaluate the effects of temperature, substrate, and luminosity on chia seeds in order to determine adequate conditions for a germination test. The experiment consisted of a completely randomized design, in a 4 × 5 × 2 factorial scheme (four substrates × five temperatures × two luminosity conditions), with four replications. The following variables were analyzed: first germination count, germination, germination speed index, and mean germination time. Germination was best at 15, 20, 25, and 30 °C for the on-paper, paper roll, and sand substrates. However, in the presence of luminosity and at 25 °C, the on-paper substrate had the highest mean. For all substrates, the lowest germination was achieved at 35 °C, proving that high temperatures reduce chia seed germination. Germination speed index was highest at 25 and 30 °C for on-paper, paper roll, and sand substrates, in both the presence and absence of luminosity. Chia seeds are considered to be neutral photoblasts. Germination tests should be performed with the on-paper substrate, at 25 °C, and with a duration of seven days. The first count should be carried out four days after establishment of the test.

ABSTRACT The family farming from the Borborema Territory-PB, Brazil, produces sweet oranges that supply the regional market. In this context, it is necessary to define standards of identity and quality, as well as to quantify the bioactive compounds in the fruit, in view of adding value and creating more competitive markets. This work sought to evaluate the quality, bioactive compounds and total antioxidant activity (TAA) of oranges from family farming. A 3x3 factorial completely randomized design was used, with three cultivars (Baía, Comum, Mimo-do-Céu) and three maturity stages (predominantly green, green/yellow, yellow), with 60 replications of 1 fruit for the physical evaluations, and 4 of 15 fruit for the others. The whole fruits were evaluated by color index, length, diameter, fresh weight and firmness. The juice was assessed for yield, pH, soluble solids (SS), titratable acidity (TA), SS/AT ratio, and ascorbic acid. Total extractable polyphenols (TEP) and ABTS•+ and DPPH• total antioxidant activity (TAA) were measured in the juice and albedo. The 'Baía' and 'Mimo-do-Céu' oranges presented quality parameters aligned with the CEAGESP standards. On average, the ascorbic acid content was higher than 45 mg 100 g-1, with ‘Mimo-do-Céu’ presenting the highest content (50.26 mg 100 g-1). During maturation, the firmness decreased, and the SS, TEP and TAA of the juice and the albedo increased. In general, the TEP content was about eight-fold higher in the albedo than juice, corresponding to the much higher TAA in this portion, thereby highlighting its higher functional potential, especially for ‘Baía’ orange.

ABSTRACT Enzyme assays are based on methodologies described in the literature. However, the enzyme kinetics must be adjusted to obtain more reliable results. This study aimed to adjust assays by testing different polyphenol oxidase (PPO) and peroxidase (POD) extract amounts and reaction times in sweet potato cultivars harvested at different times. Sweet potato cultivars Paraná, Mãe de Família, and ESAM1 were harvested at 120, 150, and 180 days after planting and minimally processed. A 0.25 g sample was used to determine PPO and POD activities immediately after minimal processing at each harvest. Extraction was performed in 1500 μL phosphate buffer (0.2 M, pH 6.0). The PPO assay was performed by adding 10-50 μL extract, 1490-1450 μL phosphate buffer (0.2 M, pH 6.0), and 1500 μL catechol (0.2 M). The POD assay was carried out by adding 10-50 μL extract to a reaction medium containing 1790-1750 μL phosphate buffer (0.2 M, pH 6), 100 μl guaiacol (5 g L-1), and 100 μL hydrogen peroxide (0.8 g L-1). In both cases, the evaluated reaction times were 1, 2, and 3 min. In the three cultivars, PPO and POD activities increased with the volume of extract and reaction time at all harvest times. The enzyme extract volume of 10 μL for 2 min promoted a continuous increase in PPO and POD enzyme activities in all studied cultivars and at all reaction times.

ABSTRACT The objective of this work was to evaluate the phenology of Calotropis procera accessions based on morphophysiological characteristics. Seeds of 70 C. procera accessions were collected between October 2015 and January 2016 in areas where the species naturally occurs in Northeastern Brazil. These accessions make up the current germplasm collection of the National Institute of the Semi-arid (INSA). The experiment was conducted in a greenhouse at INSA, in Campina Grande - PB, from January to September in 2016. The plants were cultivated in plastic pots filled with soil. Fertilization was conducted according to soil analysis recommendations and plants were irrigated at a 3-day interval. Morphophysiological characteristics were recorded 30 days after sowing (DAS) and 30-day intercalated evaluations were conducted up to 240 DAS. In addition, physiological indexes were estimated and leaf fall, flowering, and fruiting were evaluated at 120 DAS. Mean of each characteristic was obtained using the adjustment and the selection of regression models to explain the growth of C. procera based on the coefficient of determination. The vegetative stage of C. procera occurs during the 240 DAS, with continuous fall and production of leaves, while the reproductive stage begins at 153 DAS, continuing until 222 DAS, depending on the accession, making emission of inflorescences constant on plants after the beginning of flowering. The physiological indexes are efficient to estimate the growth of C. procera accessions.
