Growth of yellow passion-fruit seedlings in different substrates under salt stress

Salt stress can negatively affect the development of seedlings. However, the use of alternative substrates can mitigate these effects. The present study aimed to evaluate the growth of yellow passion-fruit seedlings in response to irrigation with saline water grown on different substrates. The experiment was developed at the University of International Integration of Afro-Brazilian Lusofonia, Redenção, Ceará, Brazil. The experimental design was entirely randomized, in a 2 × 5 factorial arrangement, composed of two levels of electrical conductivity of the irrigation water (0.3 and 3.0 dS m-1) and five substrate types (S1 = soil; S2 = sand, sandy soil, and bovine manure – 1:1:1; S3 = sand, sandy soil, and carbonized rice husk – 1:1:1; S4 = sand, sandy soil, and biochar – 1:1:1; S5 = sand, sandy soil, and vegetal ash – 1:1:1), with five replications. The S2 substrate containing sand, sandy soil, and bovine manure promoted higher performance of seedling height, stem diameter, shoot dry mass, root dry mass, and total dry mass associated with low salinity water. The S2 substrate was more efficient for leaf area, while S4 substrate was more efficient for number of leaves, root length, and pH. The S1 and S2 substrates presented higher electrical conductivity of the saturation extract using water of higher conductivity.Salt stress can negatively affect the development of seedlings.

Radish production under different shading screens and mulching

Shading Screens and mulching may provide a favorable environment for radish growing in regions of adverse climates. This work aimed to evaluate the radish productivity under the influence of different shading screens associated with the presence and absence of mulch in two different years. The experiment was carried out in two different seasons (2017 dry season and 2018 rainy season), in the vegetable garden of Liberdade campus, at the University of International Integration of Afro-Brazilian Lusophony (Unilab), municipality of Redenção-CE. The experimental design was in randomized blocks in a split-plot arrangement, with four repetitions, in which the plots consisted of growing with and without mulching and in the subplots, five shading screens: 50% Black Shading Screen (50% BSS), 50% Red Shading Screen (50% RSS), 30% White Shading Screen (30% WSS), 70% Black Shading Screen (70% BSS) ), and full sunlight (FS). The red shading screens 50% and white 30%, in addition to cultivation under full sunlight, provide higher performance in terms of the number of leaves, tuberous root diameter, tuberous root matter, and the radish crop productivity, regardless of the evaluated period. The applied mulch does not influence the productivity of the rabante, influencing only the gain of dry mass of the aerial part, soluble solids and length of the tuberous root.Shading Screens and mulching may provide a favorable environment for radish growing in regions of adverse climates.

BALANÇO HÍDRICO CLIMATOLÓGICO E CLASSIFICAÇÃO CLIMÁTICA PARA O MUNICÍPIO DE LUPÉRCIO – SP

A disponibilidade hídrica de uma região pode ser quantificada pelo balanço hídrico climatológico (BHC), que evidencia as variações sazonais dos excedentes e deficiências hídricas através de relações entre as entradas e saídas de água de uma condição de controle, principalmente precipitação pluvial (P) e evapotranspiração potencial (ETP). O objetivo deste trabalho foi calcular o balanço hídrico climatológico para o município de Lupércio – SP, utilizando cenários com diferentes disponibilidades de água no solo e realizar sua classificação climática segundo a metodologia proposta por Thornthwaite; Mather (1955). Foram utilizadas médias históricas mensais de chuva e temperatura do ar (1993-2012) para o cálculo do BHC, os cenários com variação da disponibilidade de água no solo foram com as CADs 100, 75 e 50 mm. As deficiências hídricas anuais acumuladas foram em 19 mm, distribuídas majoritariamente entre julho e setembro; para o excedente hídrico anual, o município apresenta valores de 431 mm concentrados entre os meses de dezembro a março. Verifica-se que à medida que a CAD do solo vai diminuindo, aumenta a deficiência hídrica nos meses mais secos, isso porque o solo passa a ter uma menor capacidade de armazenamento de água. Através da fórmula climática, o município foi considerado úmido, megatérmico, sem ou com pequena deficiência hídrica e com uma concentração de 32% da ETP no trimestre entre dezembro e fevereiro. Em função da variação da CAD, a fórmula climática não variou, permanecendo a mesma para as três condições simuladas

Comparison of Cognitive Performance between Elderly Training Practices with Weights and Sedentaria

Comparison of cognitive performance among elderly people practicing training with weights and sedentary lifestyle. Estudy descriptive, cross-sectional and comparative, composition for 24 elderly between 60 and 70 years, divided into 2 groups, (G1) submitted to weight training and sedentary (G2). The G1 was submitted to 32 training sessions with traditional weight. Both groups were submitted to CogState® computerized cognitive testing batteries. The data were not parametric, using the Kolmogorov-Smirnov test for the analysis of the dispersion curve and the Mann-Whitney test in the comparison of the cognitive performance variables. The results were performed with a significance level of 0.05 by the Statistical Package for the Social Sciences (SPSS®), version 16.0. The best cognitive performance was observed among the elderly practicing resistance exercises, as well as significant differences in the TRS and TRE variables. Elderly people who exercise with weights when compared with cognitive performance demonstrate results of the paradigms when compared to the elderly. With this, he concludes that weight training is effective in improving cognitive performance

O tempo médio de germinação para a variedade Arigó não sofreu alteração significativa com a presença dos sais na solução. A matéria seca do hipocótilo e raiz foram afetadas de maneira significativa somente para a variedade Arigó. A variedade Manteguinha apresentou boa tolerância à salinidade na germinação inicial, mostrando-se como uma boa alternativa para programas de seleção de obtenção de cultivares tolerantes ao estresse salino.Palavras-chave: feijão-caupi; salinidade; germinação. GERMINATION RESPONSE OF BEAN ARIGÓ AND MANTEGUINHA (Vigna unguiculata (L.) Walp) SUBMITTED TO SALT STRESS CONDITIONS ABSTRACT: The objective of this work was to evaluate the germination and seedling growth of the Creole seeds of the Juruá Valley, Acre, bean caupi (Vigna unguiculata (L.) Walp) varieties Manteguinha and Arigó, exposed to increasing levels of salinity. The experiment was conducted in a laboratory using 10 treatments and four replicates distributed in a completely randomized design in a 2 x 5 factorial scheme, two varieties of bean (Arigó and Manteguinha) and 5 levels of salinity, for a total period of 7 days. The germination index, mean germination time, hypocotyl growth, root growth, and total dry matter were evaluated. The results showed that germination (IVG), hypocotyl (CH) and root (CR) are affected with the increased salt concentrations. The mean germination time for the Arigó variety did not change significantly with the presence of the salts in the solution. The dry matter of the hypocotyl and root is affected only significantly for the arthropod variety. The variety Manteguinha presented good tolerance to the salinity in the initial germination. The butterbean variety stood out best by showing a good alternative for selection programs for obtaining salt tolerant cultivars.Keywords: cowpea beans; salinity; germination

The germline mutational landscape of BRCA1 and BRCA2 in Brazil

The detection of germline mutations in BRCA1 and BRCA2 is essential to the formulation of clinical management strategies, and in Brazil, there is limited access to these services, mainly due to the costs/availability of genetic testing. Aiming at the identification of recurrent mutations that could be included in a low-cost mutation panel, used as a first screening approach, we compiled the testing reports of 649 probands with pathogenic/likely pathogenic variants referred to 28 public and private health care centers distributed across 11 Brazilian States. Overall, 126 and 103 distinct mutations were identified in BRCA1 and BRCA2, respectively. Twenty-six novel variants were reported from both genes, and BRCA2 showed higher mutational heterogeneity. Some recurrent mutations were reported exclusively in certain geographic regions, suggesting a founder effect. Our findings confirm that there is significant molecular heterogeneity in these genes among Brazilian carriers, while also suggesting that this heterogeneity precludes the use of screening protocols that include recurrent mutation testing only. This is the first study to show that profiles of recurrent mutations may be unique to different Brazilian regions. These data should be explored in larger regional cohorts to determine if screening with a panel of recurrent mutations would be effective.This work was supported in part by grants from Barretos Cancer Hospital (FINEP - CT-INFRA, 02/2010), Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP, 2013/24633-2 and 2103/23277-8), Fundação de Apoio à Pesquisa do Rio Grande do Norte (FAPERN), Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ), Fundação de Amparo à Pesquisa do Estado do Rio Grande do Sul (FAPERGS), Ministério da Saúde, the Breast Cancer Research Foundation (Avon grant #02-2013-044) and National Institute of Health/National Cancer Institute (grant #RC4 CA153828-01) for the Clinical Cancer Genomics Community Research Network.

Aspectos anatomopatológicos das neoplasias malignas renais: Anatomopathological aspects of malignant renal neoplasms

As neoplasias renais correspondem ao crescimento exacerbado de células tumorais no interior dos rins, classificadas como benignas ou malignas. Neste estudo será abordado sobre as neoplasias malignas renais, a qual correspondem a maior prevalência e são representadas pelo carcinoma de células renais e o tumor de Wilms, com a finalidade de descrever a respeito dos aspectos anatomopatológicos, disseminando informações para o diagnóstico e manejo precoce. O carcinoma de células renais é mais prevalente no sexo masculino, indivíduos mais velhos, geralmente assintomático, contribuindo para o diagnóstico tardio junto a existência de metástases e terapêutica irresponsiva. Não se trata de uma doença genética, sendo o caráter esporádico o predominante, neste contexto os fatores de risco, sobretudo o tabagismo em seguida de obesidade hemodiálise e doenças genéticas são potenciais desencadeantes da enfermidade. Os exames complementares associado a clínica, junto ao acompanhamento eleva a possibilidade de identificação antes de avanços metastáticos. O tumor de Wilms é típico de crianças, acometendo um ou ambos os rins, normalmente com alguma anomalia genética, sendo os sinais inespecíficos, mas sempre manifestando massa palpável e dor abdominal, a qual os métodos de imagem confirmam o diagnóstico e estimam o prognóstico deste. Neste contexto, elucida-se a transcendência que os aspectos anatomopatológicos das neoplasias malignas renais oferecem para a diagnose precoce, devido a escassez e inespecificidafe das manifestações clínicas. Logo, a junção do perfil de cada neoplasia abordado conduz ao manejo adequado e reduz a incidência de tratamentos agressivos e irresponsivos
