Abstract: this study aimed to know the correlation between love and staying and how both are correlated to the life meaning and existential void. in addition, it tried to know evidences of factorial validity and reliability of the measure of love. the participants were 199 undergraduate students (51% women) with the mean age of 21 years. they answered the revised version of the life purpose test and the tetra-dimensional love scale (tls). results supported the adequacy of the tetra-factorial model for the tls. three of its factors (commitment, intimacy, and romantic passion) were positively associated with existential realization; intimacy did negatively with despair and existential void, and romantic passion did it with the existential void. with respect to staying, it was negatively correlated with the love factors commitment, intimacy and romantic passion. the discussion of these findings was based on logotherapy, that considers love a way to get the meaning of life.

Abstract: chronic myeloid leukemia (cml) have been described. this chromosomal region contains the tumor suppressor gene tp53 that may be an important factor in the evolution of this disease. in this study, we used flow cytometry and western blotting to assess p53 protein expression and single stranded conformational polymorphism to examine tp53 gene alterations in three patients with cml who showed alterations in 17p. only the case with del(17)(p11) had p53 expression positive by flow cytometry and an abnormal migration pattern by sscp analysis. the importance of the correlation between the results obtained with these techniques, as well as the clinical course of the patients, are discussed.

Amazonian Fruits: An Overview of Nutrients, Calories and Use in Metabolic Disorders  [PDF]
Moacir Couto de Andrade Júnior, Jerusa Souza Andrade
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.517182
Abstract: Amazonian fruits are outstanding in quality. They are consumed as true delicacies of nature by the Brazilian population. Besides their attractive attributes, i.e. appearance, different textures and distinctive flavors, their nutritional value is diversified in the type of calories and the functional food ingredients. In addition to being very palatable, Amazonian fruits provide energy-rich macronutrients (lipids, proteins and carbohydrates), micronutrients (minerals, water-soluble vitamins and fat-soluble vitamins), prebiotics (dietary fibers, especially pectin), bioactive substances (carotenoids and polyphenols), variety in the diet and improvement in the organoleptic properties and digestibility of (mixed) foods. This study first aimed to review concepts applicable to nutritional constituents and caloric contents of Amazonian fruits. It also attempted to clarify the potential use of these fruits in metabolic disorders (i.e. diabetes mellitus and/or obesity). To fulfill these purposes, 12 fruits were chosen for their dietetic significance in the Brazilian Amazonia.
Knocking-Down?Meloidogyne incognita?Proteases by Plant-Delivered dsRNA Has Negative Pleiotropic Effect on Nematode Vigor

Abstract: The root-knot nematode Meloidogyne incognita causes serious damage and yield losses in numerous important crops worldwide. Analysis of the M. incognita genome revealed a vast number of proteases belonging to five different catalytic classes. Several reports indicate that M. incognita proteases could play important roles in nematode parasitism, besides their function in ordinary digestion of giant cell contents for feeding. The precise roles of these proteins during parasitism however are still unknown, making them interesting targets for gene silencing to address protein function. In this study we have knocked-down an aspartic (Mi-asp-1), a serine (Mi-ser-1) and a cysteine protease (Mi-cpl-1) by RNAi interference to get an insight into the function of these enzymes during a host/nematode interaction. Tobacco lines expressing dsRNA for Mi-ser-1 (dsSER), Mi-cpl-1 (dsCPL) and for the three genes together (dsFusion) were generated. Histological analysis of galls did not show clear differences in giant cell morphology. Interestingly, nematodes that infected plants expressing dsRNA for proteases produced a reduced number of eggs. In addition, nematode progeny matured in dsSER plants had reduced success in egg hatching, while progeny resulting from dsCPL and dsFusion plants were less successful to infect wild-type host plants. Quantitative PCR analysis confirmed a reduction in transcripts for Mi-cpl-1 and Mi-ser-1 proteases. Our results indicate that these proteases are possibly involved in different processes throughout nematode development, like nutrition, reproduction and embryogenesis. A better understanding of nematode proteases and their possible role during a plant-nematode interaction might help to develop new tools for phytonematode control.

REDVET , 2006,
Abstract: O consumo e a digestibilidade s o parametros chaves em vários sistemas de formula o de dietas para ruminantes. A medi o desses parametros faz-se necessária, pois, estes possuem alta correla o com a ingest o de matéria seca e eficiência na absor o e aproveitamento dos nutrientes. O consumo de alimentos é influenciado por vários fatores e, quando a densidade energética destes é mais baixa, como é o caso de dietas a base de volumosos, o consumo poderá ser limitado pelo efeito do enchimento. The consume and the digestibility are key parameters in several systems of formulation of diets for ruminant. The measurement of those parameters is made necessary, because, these possess high correlation with the ingestion of matter dry and efficiency in the absorption and use of the nutrients. The consume of foods is influenced by several factors and, when the energy density of these it is lower, as it is the case of diets the base of roughage, the consumption can be limited by the effect of the stuffing.
