Abstract Milk and its derivatives are rich in nutrients and widely consumed by the population. However, the presence of chemical residues is frequent in these products. This study aimed to carry out a diagnosis of the use of antibacterials and evaluate the knowledge about these drugs and behaviors adopted by dairy producers in Goiás, Brazil. A total of 286 dairy farms in 36 municipalities in the State were visited and interviews were conducted with the owner or auxiliary workforce. The questions addressed the production parameters of the property and the use of antibacterials. The answers were presented in percentages and graphs. Statistical analysis was performed using Pearson’s chi-square test at a 5% significance level. Only 26.2% of the producers used antibacterials indicated by veterinarians and all producers (100%) disposed of milk with residues inappropriately. Tetracycline and penicillin were the most used among the 21 cited active principles. Enteritis (22.1%), cattle tick fever (21.1%), and mastitis (19.4%) were the main diseases treated with antibacterials. A total of 37.4% of respondents were unable to distinguish antibacterials from other drugs. Moreover, the more specialized the farm, the greater the veterinary assistance and the greater the care for antibacterial treatments. Most respondents (51.7%) had incomplete elementary education. These results provide important information about how rural producers in the State of Goiás use antibacterials and serve as a basis for future interventions. The need for greater access by producers to veterinary services in Goiás is evident to reduce the unnecessary and inappropriate use of antibacterials.

Resumo O leite e seus derivados são ricos em nutrientes e largamente consumidos pela população. Contudo, a presença de resíduos de substâncias químicas é frequente nesses produtos. Esse estudo objetivou realizar um diagnóstico sobre o uso de antibacterianos, avaliar o conhecimento sobre esses fármacos e condutas adotadas por produtores de leite em Goiás, Brasil. Foram visitadas 286 propriedades leiteiras em 36 municípios do estado, onde foram realizadas entrevistas com o proprietário ou mão de obra auxiliar. As perguntas abordavam parâmetros produtivos da propriedade e uso de antibacterianos. As respostas foram apresentadas em porcentagem e gráficos. A análise estatística foi realizada pelo teste de qui-quadrado de Pearson ao nível de significância de 5%. Apenas 26,2% dos produtores utilizavam antibacterianos indicados por veterinários e todos (100%) descartavam o leite com resíduos de forma inadequada. Dentre os 21 princípios ativos citados, os mais utilizados foram as tetraciclinas e penicilinas. As principais doenças tratadas com antibacterianos foram enterite (22,1%), tristeza parasitária bovina (21,1%) e mastite (19,4%). Observou-se que 37,4% dos entrevistados não souberam distinguir antibacterianos de outros medicamentos. Verificou-se que quanto mais especializada é a fazenda, maior é a assistência veterinária e maiores os cuidados para tratamentos com antibacterianos. A maioria dos entrevistados (51,7%) apresentava ensino fundamental incompleto. Esses resultados fornecem informações importantes sobre como os produtores rurais do estado de Goiás utilizam antibacterianos e servem como base para intervenções futuras. É evidente a necessidade de maior acesso dos produtores a serviços veterinários em Goiás, a fim de reduzir o uso desnecessário e inadequado de antibacterianos.

ABSTRACT: At the end of 2019, the world stopped because to the pandemic scenario hit by the SARS-CoV-2 virus. COVID-19 is a contagious infectious disease with a high degree of spread, which caused an outbreak of contamination and lethality in a short time. As a result there was a interruption in several sectors causing an agglomeration, including all the Universities of Dentistry. Thus, the objective of this study was to carry out a bibliographic survey about the new biosafety rules, for the resumption of activities in the school clinics of the dentistry course, in light of the new world scenario. Presenting the strategies for resuming clinical laboratory the practical activities of dentistry courses, as well as analyzing the changes made in infrastructure, new biosafety protocols in accordance with the rules advocated by the Brazilian Association of Dental Education (ABENO) and the Organization World Health Organization (WHO). A bibliographic search of the last 2 years was performed, including the following descriptors: Biosafety, COVID-19, Dentistry, Universities. Studies addressed the process of resuming classes were selected, as well as biosafety standards and new clinical-laboratory protocols. The results identified new biosafety protocols for patient care in the midst of the COVID-19 pandemic, rules and guidelines issued by Ministries and Health Associations, as well as the impacts caused on dentistry students, professionals and patients. Thus, there was a need for structural changes in schools and dental clinics in order to facilitate the correct realization of these new protocols. It is expected that the new biosafety standards addressed in the articles reviewed, are applied for a safe resumption of clinical-laboratory activities in dentistry.

RESUMEN: A finales del año 2019, el mundo se detuvo debido al escenario pandémico afectado por el virus SARS- CoV-2. La COVID-19 es una enfermedad contagiosa con un alto grado de propagación que ha provocado un brote de contaminación y letalidad en poco tiempo. Con eso, hubo la paralización de varios sectores que provocara una aglomeración, incluyendo todas las Universidades de Odontología. De esa forma, el objetivo del presente estudio fue realizar un estudio bibliográfico acerca de las nuevas reglas de bioseguridad, para la reanudación de las actividades en las clínicas escuela del curso de odontología, frente al nuevo escenario mundial. Presentando las estrategias para reanudar las actividades prácticas clinico-laboratoriales de los cursos de odontología, así como analizar los cambios realizados en infraestructura, nuevos protocolos de bioseguridad y si están de acuerdo con las reglas preconizadas por la Associação Brasileira de Ensino Odontológico (ABENO) y la Organización Mundial de la Salud (OMS). Se realizó una búsqueda bibliográfica de los últimos 2 años, contemplando los descriptores: Bioseguridad, COVID-19, Odontología, Universidades. Se seleccionaron estudios que abordaban el proceso de reanudación de las clases, así como normas de bioseguridad y nuevos protocolos clínico-laboratoriales. Los resultados encontrados identificaron nuevos protocolos de bioseguridad para la atención al paciente en medio de la pandemia de COVID-19, reglas y directrices divulgadas por Ministerios y Asociaciones de salud, así como los impactos causados en los estudiantes de odontología, profesionales del área y pacientes. Con eso, hubo la necesidad de cambios estructurales en las facultades y clínicas odontológicas para facilitar la realización correcta de esos nuevos protocolos. Con esta revisión, se espera que las nuevas normas de bioseguridad, estén siendo aplicadas conforme a los artículos y protocolos abordados en ese estudio, para una reanudación segura de las actividades clínico-laboratoriales en la odontología.

Abstract: En | Text: En | PDF: En

Abstract Crude palm oil (CPO), refined palm oil (RPO), refined palm olein (RPOL) and refined palm stearin (RPS) were stored in three conditions: kept away in dark (at 20-25 °C, acclimatized environment); in a refrigerator (4-8 °C); and at room temperature (26-32 °C), exposed to natural light. Free fatty acids (FFA; %), peroxide value (meq O2/kg), induction period (h), total carotenoids (ppm) and color measurements (CIELab) were analyzed to determine stability of oils every months until 12 months. All of the crude/refined initial oils were of good quality, except for one sample of CPO. Storage at 26-32 °C and exposure to light intensified the oxidative reactions. The estimated shelf life of CPO, RPO, RPOL and RPS, when stored at 20-25 °C and in the dark, would be approximately 6, 9, 9 and 12 months, respectively. The best quality oils was found stored at 4-8 °C when compared to those stored in other storage conditions.

Abstract: En | Text: En | PDF: En

Akara is one of Brazil's national treasures prepared from cowpea (Vigna unguiculata L.Walp), grated onions and salt and deep-fried in crude palm oil. The results of this study on akara preparation methods showed that, in general, cowpeas were soaked for up 3 hours at room temperature, and the seed coats were then removed. The akara makers preferred the olho de pombo cultivar, because of its cream hue, or the macassar cultivar because it produces a crispier paste. The seeds purchased from street markets had lower ranges of InsP6, InsP5, and InsP4 (1.03-7.62 ∝mol.g- 1; 0.14-1.31 ∝mol.g- 1; and 0.0-0.10 ∝mol.g- 1, respectively) than both the paste and akara (6.72-19.24 ∝mol.g- 1; 1.29-4.57 ∝mol.g- 1; 0.0-0.76 ∝mol.g- 1; 3.31-13.71 ∝mol.g- 1; 0.0-4.48 ∝mol.g- 1; and 0.0-1.32 ∝mol.g- 1). These results suggest that other beans or cowpea varieties have been used in the preparation of akara and that the phytate levels do not affect its nutritional quality.

PURPOSE: Tumor banks have the primary responsibility for collecting, cataloging, storing and disseminating samples of tissues, cells and fluids, which are used by researchers to identify diagnostic molecular markers, prognostic indicators and therapeutic targets. The objective of this review was to describe a simple, reliable and reproducible protocol for obtaining and storing samples of urological tumors. MATERIALS AND METHODS: Urogenital tumor tissues were collected by the surgeons from the Urology Division of University of Sao Paulo Medical School. The obtained surgical specimens were immediately placed in liquid nitrogen, dry ice or in a tube containing RNAlater ®, and then stored by cryopreservation (-80°C). A mirror fragment was fixed in 10% formalin processed routinely and embedded in Paraplast®. RESULTS: We developed a protocol for the collection, cataloging, storage, conservation and use of tumor samples. During a period of one year the Urological Tumor Bank of the Urology Division stored 274 samples of prostate, bladder, kidney, penis and testicle tumors of different histological types, 74 urine and 271 serum samples. CONCLUSIONS: Having biological materials characterized and available along with the clinical patient information provides an integrated portrait of the patients and their diseases facilitating advances in molecular biology. It also promotes the development of translational research improving methods of diagnosis and cancer treatment.

Este estudo descreve aspectos da biologia floral e sistema reprodutivo de Passiflora edulis f. flavicarpa (Passifloraceae), incluindo os padrões de forrageio e comportamento dos visitantes florais. O estudo foi desenvolvido em cultivo irrigado no Projeto Maniçoba, em Juazeiro-BA, em 2005/2006. A antese floral ocorreu entre 12h e 13h, o fechamento da flor teve início às 18h, terminando por volta de 1h. O tempo para a deflexão dos estiletes foi de 71,4 ± 12,4 min, mas cerca de 5% das flores permaneceram com os estiletes sem curvatura. Os estigmas foram receptivos durante toda a antese, e os grãos de pólen apresentaram viabilidade de 94%. O volume de néctar foi em média de 100 µL, com 48% de concentração de açúcares. O número médio de grãos de pólen/ flor foi de 140.595 ± 34.175, e 426 ± 77 óvulos/ovário. As maiores taxas de frutificação (74%) foram obtidas com polinização cruzada manual, confirmando a existência de sistema de autoincompatibilidade. Registraram-se 10% de flores com quatro estigmas que, quando polinizadas manualmente, apresentaram frutos maiores e com maior número de sementes (477,7 ± 76,8). Observou-se correlação positiva entre o número de sementes e o peso dos frutos. Os visitantes florais identificados foram Apis mellifera, Trigona spinipes, Xylocopa grisescens, X. frontalis e X. cearensis. As abelhas A. mellifera e T. spinipes foram pilhadores de pólen e néctar, respectivamente. As abelhas do gênero Xylocopa foram mais frequentes nas flores durante o período seco, e A. mellifera, durante o período chuvoso. Os polinizadores efetivos foram X. grisescens e X. frontalis, constatando-se uma limitação desses polinizadores nas áreas estudadas. Entretanto, eles foram mais frequentes em outras espécies vegetais no período chuvoso, indicando competição com as flores dos maracujazeiros pelos serviços de polinização.

This study describes aspects of floral biology and the reproductive system of Passiflora edulis f. flavicarpa (Passifloraceae), including foraging patterns of the floral visitors in the region of São Francisco Valley. The study was carried out in irrigated orchards in the Maniçoba Project, in Juazeiro-BA, during 2005 and 2006. The floral anthesis occurred between midday and 1 pm. Flower closing started at 6 pm and finished around 1 am. The time for style deflexion was 71,4 ± 12,4 min, about 5% of the flowers remained with the style undefexed. The stigmas were receptive during the entire anthesis and the pollen grains presented 94% viability. The nectar volume was in average 100 µL, with 48% of sugar concentration . The average number of pollen grains/flower was 140,595 ± 34,175 and 426 ± 77 of ovules/ovary. The highest rates were obtained after manual crossed pollination (74%), confirming the existence of a system of self-incompatibility. We registered 10% of flowers with four stigmas, which when manually pollinated, produced bigger fruits with a higher number of seeds (477,7 ± 76,8). We found a positive correlation between the number of seeds and the weight of the fruits. The flower visitors were Apis mellifera, Trigona spinipes, Xylocopa grisescens, X. frontalis and X. cearensis. A. mellifera and T. spinipes being pollen and nectar robbers, respectively. Bees of the genus Xylocopa were more frequent during the dry season and A. mellifera during the wet season. The effective pollinators were X. grisescens and X. frontalis. We found that they were limited in number in the studied areas. However they were found to be more frequent in other plant species during the rainy season which indicates that these plant species compete with the passion fruit for pollination service.

O presente estudo foi desenvolvido durante os anos de 2005/2006, em plantio comercial de mangueira, da variedade Tommy Atkins, na Fazenda Frutex, em Petrolina-PE, objetivando verificar a biologia floral, bem como o estudo comparativo sobre o comportamento, a freqüência e a sazonalidade dos visitantes florais em cultivo orgânico e convencional. As inflorescências da mangueira apresentam flores masculinas e hermafroditas, na proporção de 2:1, com predominância das primeiras na base da panícula. A antese é diurna, assincrônica, com liberação de forte odor adocicado. As flores apresentam dicogamia, caracterizada pela deiscência das anteras 24h após a antese. A produção de néctar é contínua e em pequenas quantidades, em média 0,045 µL por flor. Quanto aos visitantes florais foram registradas 21 espécies, pertencentes às ordens: Diptera, Hymenoptera, Lepidoptera e Odonata. Apis mellifera foi a espécie mais freqüente nos dois tipos de cultivo. Dentre os dípteros, destacaram-se Belvosia bicincta (17,7%) e Musca domestica (10,2%) como as mais freqüentes em cultivo convencional e orgânico, respectivamente. A diversidade e o número de visitas foram maiores em cultivo orgânico. A utilização de agrotóxicos durante a floração reduziu a freqüência de visitas das abelhas em 50% e dos dípteros em 20%. Devido ao seu comportamento, freqüência e ativo deslocamento nas inflorescências, A. mellifera foi considerada como o polinizador mais eficiente da cultura para a região do Vale do Submédio São Francisco.

This study was carried out in 2005 and 2006, in a commercial mango Tommy Atkins plantation on Frutex Farm, in Petrolina-PE. The objective was to verify the floral biology as well as the comparative study of behaviour, the frequency and the seasonality of the floral visitors in both organic and conventional crops. The mango tree inflorescences present male and hermaphrodite flowers (2:1), with predominance of the first ones in the basis of the panicles. The anthesis is diurnal, asynchronic, with liberation of strong and sweat odour. The flowers present dicogamy, characterized by the anthers dehiscence 24 hours after the anthesis. The nectar production is continuous and in small amounts, on an average of 0,045µL/flower. Concerning the flower visitors, 21 species were registered, belonging to the orders Diptera, Hymenoptera, Lepidoptera and Odonata. Apis mellifera was the most frequent visitant in both types of crops. Among the Diptera, Belvosia bicincta (17,7%) and Musca domestica (10,2%) were the most frequent visitors in conventional and organic crops, respectively. The diversity and number of visitors were higher in the organic crop. The use of agrotoxics during the flowering period reduced the visit of bees (50%) and Diptera (20%). Because of its behaviour, frequency and active movement in the inflorescences, Apis mellifera was considered as the most efficient pollinator of the crop for the region of the São Francisco Submédio Valley.
