A produção de mudas de qualidade está relacionada a diversos fatores incluindo a qualidade da água de irrigação que dependendo da quantidade de sais nela dissolvidos pode afetar negativamente a germinação e vigor das sementes e mudas. Desse modo, o objetivo deste experimento foi avaliar a germinação e o desenvolvimento das mudas de maxixeiro em condições de estresse salino a partir de sementes tratadas com diferentes doses de bioestimulante. Para isso, utilizaram-se sementes de maxixeiro, cv. Liso de Calcutá, submetidas a dois níveis de salinidade da água de irrigação (0,5 e 3,5 dS m-1) e cinco doses do bioestimulante Stimulate® (0; 5; 10; 15 e 20 mL kg-1 de sementes) em delineamento experimental inteiramente casualizado, em esquema fatorial 2 x 5, com quatro repetições de 40 sementes. Avaliou-se ao final do experimento a emergência de plântulas, índice de velocidade de emergência, número de folhas, diâmetro do colo, altura de plântula, comprimento da raiz, massa seca de raiz, massa seca da parte aérea e total. A análise dos resultados indicou que mudas de melhor qualidade foram obtidas a partir do tratamento de sementes com bioestimulante na dosagem de 10 mL kg-1 de sementes; porém, o uso de água salina reduz consideravelmente o desenvolvimento de mudas de maxixeiro e inibe o efeito benéfico do bioestimulante.

Quality seedling production is related to various factors including irrigation water quality which, depending on the quantity of salts dissolved in it, can negatively affect seed germination, seed vigor and seedling growth. The aim of this experiment was thus to evaluate gherkin seedling germination and development in saline stress conditions using seeds treated with different doses of biostimulant. To do so, gherkin seeds cv. Liso de Calcutá, were subject to two levels of irrigation water salinity (0.5 and 3.5 dS m-1) and five doses of Stimulate® biostimulant (0, 5, 10, 15, and 20 mL kg-1 of seeds) in a completely randomized experimental framework using a 2 x 5 factorial design with four 40 seed repetitions. Seedlings emergence, emergence speed index, number of leaves, root collar diameter, plantlet height, root length, dry mass of root and of aerial part, and total dry mass were evaluated at the end of this experiment. The results indicated that high quality seedlings were obtained using seed treatment with a biostimulant in 10 mL kg-1 of seed doses; however, the use of saline water considerably reduced gherkin seedling development and inhibited the beneficial effect of biostimulants.

RESUMO O objetivo deste trabalho foi avaliar o uso de água salina na cultura do pepineiro cultivado com substrato composto por fibra de coco e areia fina lavada (1:1) utilizando o método de divisão do sistema radicular. O experimento foi realizado com o uso do delineamento inteiramente casualizado, com oito tratamentos e quatro repetições. Os tratamentos foram obtidos pela combinação de dois níveis de salinidade da solução nutritiva (1,65 e 6,25 dS m-1), com ou sem divisão do sistema radicular (S/S). Foram avaliadas as variáveis de crescimento e de rendimento. O uso de água com salinidade de 6,25 dS m-1 no preparo da solução nutritiva provoca redução significativa em todas as variáveis de crescimento e de produção do pepineiro. O uso do sistema de divisão das raízes com aplicação de dois tipos de água simultaneamente, aumentou a tolerância do pepineiro à salinidade.

ABSTRACT The objective of this study was to evaluate the use of saline water to grow cucumbers cultivated in substrate composed of coconut fiber and washed fine sand (1:1) and submitted to split-root system. The experimental design was completely randomized, with eight treatments and four replicates. Treatments consisted of different fertigation managements, comprising two nutrient solutions of different electrical conductivities (1.65 and 6.25 dS m-1), applied in a continuous or alternated way, with splitting or not of the root system (S/S). Growth and yield variables were evaluated. The use of water with electrical conductivity of 6.25 dS m-1 to prepare the nutrient solution caused significant reduction in all variables of cucumber growth and production. Adoption of split-root system with simultaneous application of the two water types increased cucumber tolerance to salinity.

The dissertation on which this article is based, has been a polemical study aimed at exploring the sacramental theology of the late Roman Catholic theologian, Edward Schillebeeckx and thereby using it as a 'foil' against which to propose an alternative, if not renewed, ecclesiology for Protestant Evangelicalism. The study accomplished this aim within the framework of a systematic theological method with an approach that was inclusive of theological inquiry as well as sociological theory and praxis. Engaging Schillebeeckx with some significant conversation partners, both Roman Catholic and Protestants, has drawn out his hermeneutical inconsistencies. Two observations have emerged from this informed dialogue: Firstly, it established Schillebeeckx's sacramental theology as upholding the systemic awareness of Roman Catholic sacramental thought. Secondly, insofar as the Protestant tradition is concerned, it established that, in spite of the diverse sacramental views within Reformation thought and Protestant evangelicalism, in particular, the doctrine of grace is upheld as foundational for the church. With a more directed focus on the diverse views concerning the Lord's Supper, the dissertation honed in on the trajectories of Zwingli ('symbolic memorialism'), Bullinger ('symbolic parallelism') and Calvin ('symbolic instrumentalism'). Emerging from this exploration, a Zwingli-Bullinger confluence has been proposed.

Linfomas T periféricos (PTCLs) compreendem um grupo heterogêneo de neoplasias que derivam das células linfoides pós-tímicas nos diversos estágios de maturação, com diversos padrões histológicos, fenotípicos, e clínicos. PTCLs são muito diversos entre si e refletem diversas células das quais foram originadas e são atualmente subclassificadas, usando-se a classificação da Organização Mundial da Saúde (OMS) 2008, apresentada neste texto na tabela 1. PTCLs compreendem 5%-10% de todas as doenças linfoproliferativas no mundo ocidental, com uma incidência global de 0.5 a 2 a cada 100.000 pessoas por ano e têm uma distribuição epidemiológica diversa com maior incidência na Ásia. Os achados clínicos dos PTCLs são muito heterogêneos. PTCLs expressam muito maior variação de apresentações clínicas do que os linfomas B, e há uma íntima, mas não absoluta, relação entre algum achado clínico não usual e certos subtipos histológicos.

Peripheral T-cell lymphomas (PTCLs) comprise a heterogeneous group of neoplasms that are derived from post-thymic lymphoid cells at different stages of differentiation and with different morphological patterns, phenotypes, and clinical presentations. PTCLs are highly diverse, reflecting the diverse cells from which they can originate and are currently sub-classified using World Health Organization (WHO) 2008 criteria. Peripheral T-Cell Lymphomas account for 5%-10% of all lymphoproliferative disorders in the Western hemisphere, with an overall incidence of 0.5-2 per 100,000 individuals per year, and have a striking epidemiological distribution, with higher incidence in Asia. The clinical features of PTCL are extremely heterogeneous. PTCLs express even more clinical diversity than B-cell non-Hodgkin's lymphomas, and there is a close, though not absolute, relationship between some unusual clinical features and certain histological subtypes.

The apical membrane antigen (AMA-1) family of malaria merozoite proteins is characterised by a high degree of inter-species conservation. Evidence that the protein (PK66/AMA-1) from the simian parasite Plasmodium knowlesi was protective in rhesus monkeys suggested that the 83kDa P. falciparum equivalent (PF83/AMA-1) should be investigated for protective effects in humans. Here we briefly review pertinent comparative data, and describe the use of an eukaryotic full length recombinant PF83/AMA-1 molecule to develop a sensitive ELISA for the determination of serological responses in endemic populations. The assay has revealed surprisingly high levels of humoral response to this quantitatively minor antigen. We also show that PK66/AMA-1 inhibitory mAb's are active against merozoites subsequent to release from schizont-infected red cells, further implicating AMA-1 molecules in red cell invasion.
