    O uso eficiente da água e a diversificação ambiental são fundamentais para o equilíbrio e a sustentabilidade dos sistemas orgânicos de produção de tomate. O presente estudo teve por objetivo avaliar a produção de tomate de mesa em cultivo solteiro e consorciado com coentro com irrigação por aspersão e gotejamento, em sistema orgânico. O experimento foi conduzido em área de produção orgânica no Distrito Federal. O delineamento foi blocos ao acaso, com tratamentos dispostos num arranjo fatorial 2 x 2 (dois sistemas de irrigação x dois sistemas de cultivo). Não houve interação significativa entre os fatores avaliados, assim como não houve efeito do sistema de cultivo sobre as variáveis avaliadas. Embora o ciclo do tomateiro irrigado por gotejamento tenha diminuído, a produtividade de frutos não foi afetada pelos sistemas de irrigação. A maior redução de estande verificada na aspersão foi compensada por um aumento no número de frutos por planta, sem variação na massa por fruto. O menor volume de solo explorado pelas raízes do tomateiro associado à maior incidência de traça-o-tomateiro (Tuta absoluta) e principalmente de oídio (Leveillula taurica) pode ter limitado a produtividade do tomateiro irrigado por gotejamento. A taxa de frutos podres na aspersão foi o dobro da verificada no sistema por gotejamento

    A nanomultilayer coating made of food-grade, bio-based materials (consisting of five nanolayers of pectin and chitosan) was produced. This coating was firstly characterized in terms of the water vapor, oxygen and carbon dioxide permeabilities; these parameters exhibited values of 0.019 ± 0.005 × 10−11, 0.069 ± 0.066 × 10−14 and 44.8 ± 32 × 10−14 g m/(Pa s m2), respectively, and are of the same order of magnitude of those found in other nanomultilayer systems. The nanomultilayer system was applied on whole ‘Tommy Atkins’ mangoes and the layers’ adsorption was confirmed by changes in the contact angle of the coated fruits’ skin. After 45 d of storage, uncoated mangoes presented a higher mass loss, higher total soluble solids and lower titratable acidity in comparison with coated mangoes. Uncoated mangoes had also a damaged and wrinkled appearance, showing evidence of microbial spoilage, and the flesh exhibited a slightly brownish color, in comparison with the coated mangoes. These results suggest a positive effect of the coating on gas flow reduction and on the consequent extension of the shelf-life of mangoes.The author Bartolomeu G.S.

    Summary The presented work had as main approach to analyze the process of expropriation of the small agricultural producers and the intensification of the temporary work in the Region of Presidente Prudente, in the State of São Paulo. Such process if aggravated in virtue of the expansion of the culture of the sugar cane-of-sugar from years 1980, reducing the possibilities of access to the culture of the land for the small producers. In this context, the analysis was accomplished in the District of Guachos, city of Martinópolis, for reflecting of sharp form the characteristics of formation of the temporary work. In this direction, one became excellent to understand the process of constitution of a reserve of projecting man power in the District in I appraise, emphasizing the influence of the sugar cane-of-sugar plants on the local man power. Key words: Modernization; Agricultural Worker; Cattle; Sugar cane-of-sugar, Sazonalidade.O trabalho apresentado teve como enfoque principal analisar o processo de expropriação dos pequenos produtores rurais e a intensificação do trabalho temporário na Região de Presidente Prudente, no Estado de São Paulo. Tal processo se agravou em virtude da expansão da cultura da cana-de-açúcar a partir dos anos 1980, reduzindo as possibilidades de acesso ao cultivo da terra pelos pequenos produtores. Neste contexto, a análise efetivou-se no Distrito de Guachos, município de Martinópolis, por refletir de forma pronunciada as características de formação do trabalho temporário.

    Background This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer. Objectives To evaluate the benefits and risks of laparoscopy compared with laparotomy for the surgical treatment of FIGO stage I ovarian cancer (stages Ia, Ib and Ic). Search methods For the original review, we searched the Cochrane Gynaecological Cancer Group Trials (CGCRG) Register, Cochrane Central Register of Controlled Trials (CENTRAL 2007, Issue 2), MEDLINE, EMBASE, LILACS, Biological Abstracts and CancerLit from 1 January 1990 to 30 November 2007. We also handsearched relevant journals, reference lists of identified studies and conference abstracts. For this updated review, we extended the CGCRG Specialised Register, CENTRAL, MEDLINE, EMBASE and LILACS searches to 6 December 2011. Selection criteria Randomised controlled trials (RCTs), quasi-RCTs and prospective cohort studies comparing laparoscopic staging with open surgery (laparotomy) in women with stage I ovarian cancer according to FIGO. Data collection and analysis There were no studies to include, therefore we tabulated data from non-randomised studies (NRS) for discussion. Main results We performed no meta-analyses. Authors’ conclusions This review has found no good-quality evidence to help quantify the risks and benefits of laparoscopy for the management of earlystage ovarian cancer as routine clinical practice

    Polysaccharide/protein nanomultilayer coatings: construction, characterization and evaluation of their effect on 'Rocha' pear (Pyrus communis L.) shelf-life

    Get PDF
    Nanolayered coatings of κ-carrageenan, a polysaccharide with good gas barrier properties, and lysozyme, a protein with antimicrobial action, were in a first stage assembled on aminolysed/charged polyethylene terephthalate (PET) pieces, which acted as a support, by alternate five-layer deposition. This was performed to allow the characterization of the nanomultilayer system. PET aminolysis was confirmed by Fourier transform infrared spectroscopy and contact angle, and the subsequent layer adsorption on aminolysed PET surface was confirmed by absorbance, contact angle and SEM images. The water vapour permeability and the oxygen permeability (O2P) of the five layers were found to be 0.013 ± 0.003 × 10−11 and 0.1 ± 0.01 × 10−14 g m−1 s−1 Pa−1, respectively. The nanomultilayer system was subsequently applied (without PET support) directly on ‘Rocha’ (Pyrus communis L.) fresh-cut pears and whole pears. Uncoated fresh-cut pears and whole pears presented higher mass loss, higher total soluble solids (TSS) and lower titratable acidity when compared with coated fresh-cut pears and whole pears. Uncoated fresh-cut pears also presented a darker colour. These results showed that the nanolayered coating assembled on the fruits’ surface has a positive effect on fruit quality and contributed to extend the shelf-life.Author Bartolomeu G. de S.

    Social isolation disrupts hippocampal neurogenesis in young non-human primates

    Social relationships are crucial for the development and maintenance of normal behavior in non-human primates. Animals that are raised in isolation develop abnormal patterns of behavior that persist even when they are later reunited with their parents. in rodents, social isolation is a stressful event and is associated with a decrease in hippocampal neurogenesis but considerably less is known about the effects of social isolation in non-human primates during the transition from adolescence to adulthood. To investigate how social isolation affects young marmosets, these were isolated from other members of the colony for 1 or 3 weeks and evaluated for alterations in their behavior and hippocampal cell proliferation. We found that anxiety-related behaviors like scent-marking and locomotor activity increased after social isolation when compared to baseline levels. in agreement, grooming an indicative of attenuation of tension was reduced among isolated marmosets. These results were consistent with increased cortisol levels after 1 and 3 weeks of isolation. After social isolation (1 or 3 weeks), reduced proliferation of neural cells in the subgranular zone of dentate granule cell layer was identified and a smaller proportion of BrdU-positive cells underwent neuronal fate (doublecortin labeling). Our data is consistent with the notion that social deprivation during the transition from adolescence to adulthood leads to stress and produces anxiety-like behaviors that in turn might affect neurogenesis and contribute to the deleterious consequences of prolonged stressful conditions.Universidade Federal de São Paulo, Dept Fisiol, BR-04023062 São Paulo, BrazilUniv Fed Rio Grande do Norte, Dept Fisiol, BR-59072970 Natal, RN, BrazilUniv Fed Rural Rio de Janeiro, Dept Ciencias Fisiol, Rio de Janeiro, BrazilUniversidade Federal de São Paulo, Dept Fisiol, BR-04023062 São Paulo, BrazilWeb of Scienc

    OBJECTIVE: Pain is a high incidence symptom in cancer patients. In cases of breast cancer, the post mastectomy and post axillary curettage pain syndromes present the characteristic of neural pain and can occur in 10% of patients shortly after surgery. This paper presents the preliminary results of an ongoing research aimed at investigating the possible effects of a modern procedure of information, which used in the evaluation of perception of pain in mastectomy patients at the Mastectomy Center of the Hospital de Clínicas de Porto Alegre, southern Brazil. MATERIALS AND METHODS: A sample of 22 patients was studied according to the classical experimental design with two groups. An informational video was shown to the  experimental group in the pre-surgery period. Both groups were evaluated using the McGill Pain Questionnaire and the Visual Analogue Scale pain score. RESULTS: Results indicated a tendency to reports of more post-surgical pain in the control group in both tests. In some of the subscales of the McGill Questionnaire there were significantly higher scores of post-surgical pain in the control group. CONCLUSIONS: Our findings seem to indicate the benefits of using informational videos with the objective of improving the well-being of patients. However, further studies should be carried out with larger population samples in order to better evaluate the trends observed in this studyOBJETIVO: A dor é um sintoma de alta ocorrência nos casos de câncer. No câncer de mama, as síndromes dolorosas pós-mastectomia e pós-esvaziamento axilar têm a característica de uma dor neural e chegam a ocorrer em 10% das pacientes, podendo aparecer imediatamente após a cirurgia. Este trabalho traz os primeiros resultados de uma pesquisa em andamento, elaborada para investigar os possíveis efeitos de um procedimento moderno de informação na avaliação da percepção de dor de pacientes submetidas à mastectomia no Serviço de Mastologia do Hospital de Clínicas de Porto Alegre.MATERIAIS E MÉTODOS: Uma amostra de 22 pacientes foi estudada segundo o delineamento experimental clássico, com dois grupos. O vídeo de informação foi apresentado no período pré-operatório apenas ao grupo experimental. Ambos os grupos foram avaliados em termos de dor, através do Questionário de McGill e da Escala Análogo-Visual de Dor.RESULTADOS: Os resultados revelaram tendências de maior avaliação da dor pósoperatória no grupo controle em comparação ao grupo experimental, em ambos os testes. Em algumas subescalas do Questionário de McGill houve aumento significativo dos escores de dor após a cirurgia no grupo controle.CONCLUSÕES: Esses achados parecem indicar a utilidade do vídeo de informação com vistas ao bem-estar das pacientes. Sugere-se, entretanto, o aumento da amostra da pesquisa para a melhor avaliação das tendências encontradas

    Introduction: patient safety, in the current context, began to be investigated in the different health fields, aiming to reduce the incidence of damages and adverse events to patients. Objective: to identify and analyze adverse events that compromise patient safety during nursing care in a private hospital. Methods: exploratory, documentary and retrospective research. The instrument of data collection was the report of adverse event notification used by the hospital composed of open and closed questions. Results: the researchers analyzed 262 reports of adverse/incident events that occurred in the period 2015 to 2016. The contributing factors for the occurrence of adverse events were caused by human failure. Of the total number of forms analyzed, 161 (61.83%) reported carelessness and distraction. The omission was highlighted with 11 (4.20%) cases. The lack of attention with the patient led to 116 (44.27%) errors in medication administration, 46 (17.56%) failures during the typing and transcription of the medical prescription and 35 (13.36%) failures in care. Conclusion: the incidents are caused by human factors, with possible reversion. When investigated, they can be minimized, which contributes to quality and safety in patient care.Introducción: La seguridad del paciente, en el contexto actual, pasó a ser investigada en los diversos campos de la salud, con el objetivo de reducir la incidencia de daños y eventos adversos a los pacientes.
