No shame to play: Ludic prosumption on Brazilian fanvideos

Purpose – Fans are proactive consumers of pop culture products, who can be seen as prosumers. Fanvideo production is one of their most widespread practices in the participatory culture scenario. Thus, the aim of the present study is to analyze how ludic prosumption is featured on plays performed in Brazilian fanvideos based on successful pop culture franchises.Design/methodology/approach – Research based on the interpretive content analysis of fanvideos of plays produced by Brazilian fans based on five emblematic pop culture franchises and published on YouTube.Findings – Results have shown six play types in the analyzed fanvideos – i.e. child’s play, performing powers, cosplay, play in social rites, teaching to play and “zu^era” –, which revealed a way of having fun in different situations through different practices based on ludic consumption experiences in different spheres of social life.Originality/value – CCT-based studies focused on investigating plays as ludic consumption phenomenon, as well as fan culture, remain at early research stage. Thus, the main contribution of the present study lies on associating such concepts based on the concept of prosumption

Spondias purpurea

Spondias purpurea is used in folk medicine to treat diarrhea and diuresis. The objective of this study was to evaluate the phytochemical profile and antioxidant and antiulcer activities of the hexane extract of the leaves of S. purpurea (SpHE). Phytochemical profile was evaluated via thin layer chromatography (TLC) and HPLC. SpHE was screened for antioxidant activities using DPPH, ABTS, FRAP, and phosphomolybdenum assays. To determine its antiulcer properties, animals were pretreated with injured control, lansoprazole, ranitidine, carbenoxolone, or SpHE (12.5, 25, and 50 mg/kg) and were screened; acute ulcers were induced by HCl/ethanol, absolute ethanol, and nonsteroidal anti-inflammatory drug (NSAID). TLC revealed the presence of flavonoids, whereas HPLC analysis showed the presence of caffeic acid and epigallocatechin. The phenolic compounds and in vitro assays showed antioxidant activity. After gastric ulcer induction by using HCl/ethanol, SpHE reduced the area of ulcerative lesions by 82, 91, and 88%, respectively. In ethanol, SpHE reduced the area of ulcerative lesions by 77, 93, and 92%, respectively. In the NSAID, the percentages of protection were 70, 76, and 78%, respectively. SpHE promoted the minimization of ulcers, increased the levels of reduced glutathione, and decreased tumor necrosis factor. S. purpurea has antioxidant and antiulcer properties

Os estudos propiciaram apreender os aspectos do contexto psicossocial, tão importantes e necessários no sentido de olhar mais atentamente a prática assistencial da enfermagem. Descritores: Enfermagem. Câncer. Prevenção

Terrestrial behavior in titi monkeys (Callicebus, Cheracebus, and Plecturocebus) : potential correlates, patterns, and differences between genera

For arboreal primates, ground use may increase dispersal opportunities, tolerance to habitat change, access to ground-based resources, and resilience to human disturbances, and so has conservation implications. We collated published and unpublished data from 86 studies across 65 localities to assess titi monkey (Callicebinae) terrestriality. We examined whether the frequency of terrestrial activity correlated with study duration (a proxy for sampling effort), rainfall level (a proxy for food availability seasonality), and forest height (a proxy for vertical niche dimension). Terrestrial activity was recorded frequently for Callicebus and Plecturocebus spp., but rarely for Cheracebus spp. Terrestrial resting, anti-predator behavior, geophagy, and playing frequencies in Callicebus and Plecturocebus spp., but feeding and moving differed. Callicebus spp. often ate or searched for new leaves terrestrially. Plecturocebus spp. descended primarily to ingest terrestrial invertebrates and soil. Study duration correlated positively and rainfall level negatively with terrestrial activity. Though differences in sampling effort and methods limited comparisons and interpretation, overall, titi monkeys commonly engaged in a variety of terrestrial activities. Terrestrial behavior in Callicebus and Plecturocebus capacities may bolster resistance to habitat fragmentation. However, it is uncertain if the low frequency of terrestriality recorded for Cheracebus spp. is a genus-specific trait associated with a more basal phylogenetic position, or because studies of this genus occurred in pristine habitats. Observations of terrestrial behavior increased with increasing sampling effort and decreasing food availability. Overall, we found a high frequency of terrestrial behavior in titi monkeys, unlike that observed in other pitheciids

FATORES DE INFLUÊNCIA DO PIB PER CAPITA DOS ESTADOS BRASILEIROS: UMA ANÁLISE DE PAINEL COM O USO DOS MÉTODOS PCSE E FGLS (1991-2009)

This paper aims to assess the significance of a set of economic, social and human capital variables found in the literature as influencing factors of Brazilian states´ GDP per capita between 1991 and 2009. In this regard, we estimated a panel data by the method of Feasible Generalized Least Squares (FGLS), proposed by Parks (1967) and the method of Panel Corrected Standard Errors (PCSE), developed by Beck and Katz (1995). The FGLS and PCSE methods produced good estimates for the coefficients, being all statistically significant and with expected sign. The results corroborate the findings of the literature.Este trabalho tem como objetivo avaliar a significância de um conjunto de variáveis econômicas, sociais e de capital humano, encontradas na literatura, como fatores de influência do PIB per capita dos estados brasileiros entre os anos de 1991 e 2009. Para tanto, estima-se um painel de dados por meio do método Feasible Generalized Least Squares (FGLS), proposto por Parks (1967), e do método Panel Corrected Standard Errors (PCSE), desenvolvido por Beck e Katz (1995). Os métodos FGLS e PCSE produzem boas estimativas para os coeficientes, sendo todos significativos estatisticamente e com sinal esperado. Os resultados encontrados corroboram os achados da literatura

Antiulcer Activity and Potential Mechanism of Action of the Leaves of Spondias mombin L.

Spondias mombin L. is used in folk medicine for the treatment of inflammation and gastrointestinal diseases. Our study investigated the antiulcer activity of S. mombin ethanolic extract (SmEE) and its majority compounds gallic acid (GA) and ellagic acid (EA). Phytochemical characterization was performed by HPLC. The SmEE was screened for in vitro antioxidant activities using phosphomolybdenum, ABTS, DPPH, and FRAP assays. The antiulcer activity of SmEE, GA, EA, or GA + EA was evaluated by gastric lesion models induced by absolute ethanol and indomethacin. Following this, it is capable of stimulating mucus production, antisecretory capacity, and the influence of −SH groups and NO in the effect of SmEE. Its healing activity was demonstrated by acetic acid-induced chronic ulcer model. Anti-Helicobacter pylori activity was assessed by determining the MIC of the SmEE (64–1024 μg/mL). The HPLC results identified the presence of gallic acid and ellagic acid in SmEE. The extract showed antioxidant activity in vitro. SmEE (50, 100, and 200 mg/kg) reduced the area of ulcerative lesions induced by ethanol in 23.8, 90.3, and 90.2%, respectively. In NSAID model, the SmEE induced protection of 36.8, 49.4, and 49.9%, respectively. GA (10 mg/kg) or EA (7 mg/kg) or the association of GA + EA (10 + 7 mg/kg) inhibited the ethanol-induced lesions in 71.8, 70.9, and 94.9%, respectively, indicating synergistic action. SmEE (100 mg/kg) decreased acid secretion and H+ concentration in the gastric contents, increased levels of mucus, and showed to be dependent of −SH groups and NO on the protection of the gastric mucosa. In chronic ulcer model, SmEE reduced the gastric area lesion. SmEE showed anti-H. pylori activity. In conclusion, our study showed that SmEE has antiulcerogenic activity. GA and EA are isolated gastric protectors and, when associated, acted synergistically to protect the gastric mucosa
