O que caracteriza o jornalismo de variedades na imprensa brasileira? O que confere identidade aos cadernos e seções culturais que focalizam o lazer e cobrem o entretenimento? São os gêneros e formatos jornalísticos? Ou são os conteúdos temáticos? Quais os parâmetros para compreender de que maneira as pautas de cultura e entretenimento têm sido apropriados por jornais editados no país? Para dar respostas a essas questões, foram observados, sistematicamente, a forma e o conteúdo de cinco publicações regionais Diário do Nordeste, Correio do Povo, Valeparaibano, Agora São Paulo e Gazeta do Tatuapé , além de um periódico de prestígio nacional Folha de S.Paulo. Optando pelo método misto de pesquisa quantitativa e qualitativa , a investigação mapeia, além dos gêneros, a geografia política, a cartografia cultural e as temáticas das matérias vigentes nos espaços já mencionados, a fim de estabelecer comparações. Os resultados sinalizam uma diversidade de produções, as quais respeitam as singularidades das regiões em que se inserem. Em geral, pode-se dizer que, na editoria de variedades, figuram tanto assuntos comuns ao jornalismo cultural música, artes visuais, artes cênicas, cinema, etc. quanto matérias a respeito de atrações televisivas, celebridades, tendências comportamentais e outros assuntos ligados à diversão, ocupando espaço significativo nas páginas dos impressos. Como reflexo da preferência dos veículos por uma produção jornalística voltada à indústria cultural e aos shows midiáticos, a cultura massiva se mostrou predominante em todas as publicações analisadas. Todavia, mesmo que a tônica do jornalismo de variedades esteja na diversão, essa especialidade não se caracteriza como um produto de entretenimento; o que ela faz é orientar como e onde se divertir. Não por acaso, constatou-se que os gêneros jornalísticos do espaço em questão, salvo raras exceções, estão circunscritos ao informativo e ao utilitário. Muito mais do que gerar cultura e entretenimento, as variedades cumprem o papel de guia do lazer.(AU)

The cowpea (Vigna unguiculata L. Walp) is a major food crops in northeastern Brazil. In Rio Grande do Norte, the cowpea, vigna beans or cowpea, as it is known, has great socioeconomic importance as a source of nutrients in food, with great emphasis among agricultural products. To improve productivity and resistance to pests, two cultivars were developed exclusively by EMPARN (Agricultural Research Corporation of Rio Grande do Norte), for breeding. The samples were provided by EMPARN, two improved (Potiguar and Laugh year) and two landraces (Rib of beef and Canapu). The seeds were ground and made into flour samples and the determination of moisture and ash by graviméticos methods, lipids by Soxhlet extraction, fibers with determiner fiber, carbohydrates by difference and minerals by ICP-OES were performed except the match analyzed by UVvis. The results showed a high fiber content (55.55% and 55.32% and 50.04% improved samples and 50.32% creole samples) and protein (25.52% and 25.27% improved and 27 samples, 23% and 24.99% creole samples). Comparing the results of the mineral content, the improved cultivars stood out in relation to Ca, Co, P, Mg, Mo and Na. Creole cultivars showed better results for Cu, Cr (low), Fe, Mn, Ni, K and Zn. The results will be important in future nutritional research and to build a table of Brazilian chemical composition of foods.

The medicinal plants constitute a rich source of biologically active compounds used for the treatment of many psychiatric disorders, such as anxiety disorders and depression. Generalized anxiety disorder has increased significantly, being the second most prevalent disorder in care facilities to public health. Depression is considered a chronic and common psychiatric disorder that affects 350 million people of all ages around the world. In this context, the pharmacological intervention conduits have been employed, effective, although leave to be desired when observed adverse effects. The genus Passiflora is commonly commercially known by its fruit, but is also widely used in traditional Brazilian medicine. Passiflora edulis displays considerable morphological variability. This plant produces two types of fruit: Purple (Passiflora edulis Sims fo. edulis) and yellow (Passiflora edulis fo. flavicarpa Degener). This study investigated the central effects of aqueous extract of the leaves of the two varieties of the species Passiflora edulis in tests used to assess behavior related to anxiety and depression, as well as investigating the potential effect of the antidepressant-like fractions of edulis fo. edulis and neuropharmacological mechanisms responsible for this action. To conduct this study used male Swiss mice (2 months old, weighing 30-35 g). The animals received the aqueous extract of the leaves of the two species of Passiflora: edulis fo. edulis (100, 300, 1000 mg / kg) and fractions ethyl acetate, butanol and aqueous waste (25, 50, 75, 100 mg / kg) and edulis fo. flavicarpa (30, 100, 300, 1000 mg / kg) or saline by gavage 60 minutes prior to the maze tests at high cross the open field test, test forced swim test and sedation induced by thiopental. To investigate the mechanism of action of the activity of antidepressant type of fractions the following drugs were used: PCPA (inhibitor of 5-HT synthesis) AMPT (inhibitor of catecholamine synthesis), DSP-4 (noradrenergic neurotoxin) and Sulpiride (antagonist selective dopamine D2 receptor). They were used as a standard positive control, fluoxetine and nortriptyline. The results of the phytochemical profile show very different characteristics to the aqueous extract of the varieties of Passiflora edulis "flavicarpa" and "edulis". The aqueous extracts of both varieties of Passiflora edulis share anxiolytic activity type (edulis fo. edulis 300 mg/kg; edulis fo. flavicarpa 300 and 1000 mg/kg) and antidepressant (edulis fo. edulis 300 mg/kg; edulis fo flavicarpa 1000 mg/kg), while the effect hipolocomotor/sedative was only seen for edulis fo. edulis (1000 mg/kg). Both fractions ethyl acetate, butanol aqueous extract edulis fo. edulis showed activity type antidepressant at a dose of 50 mg/kg in the forced swim test. The data suggest that the effect of antidepressant-like fractions edulis fo. edulis involves catecholaminergic and serotonergic neurotransmission, particularly dopaminergic, there is seen that pre-treatment DSP-4 is not affected antidepressant action of fractions as was dependent activation of dopamine D2 receptors.
