Cinema itinerante no Rio Grande do Norte: aspectos da recepção

In itinerant film projects made in Brazil, the unique experience of watching movies on the big screen is held in open spaces, through the establishment of a contemporary ritual, under which the presence of spectators is primordial. Considering this dynamic of the performance of itinerant cinema, the main objective of this research is to analyze the process of reception of the spectators of the sessions of Cine Sesi Cultural, conducted by the Social Service Industry - Sesi, in Rio Grande do Norte state. The body of research was composed by the audience of the movie sessions of the edition developed in 2010. Analyses were made from the look on the specific audience of open sessions of this cinema project throughout a case study. Theoretical authors of Latin American as Jesus Martin-Barbero, Guillermo Orozco, Eliseo Veron and Nestor Garcia Canclini, which have important theoretical basis for the analysis of research on the cinematographic reception of the spectators, were taken as a basis. In this discussion are associated with contributions from Brazilian authors as Roseli Paulino, Fernando Mascarello, Mauro Wilton Souza, Nilda Jacks and Carolina Escostesguy. Besides the reception study, the research focuses on aspects that relate to and explain the circumstances in which itinerant cinema emerges as an alternative exhibition, for example, the context of the exhibition of films in the country, lack of public policies in the audiovisual sector, and mainly the closing of movie theaters in the inner cities of the country and the consequent migration of these rooms to the malls. Seeking to reduce the existing gap in the studies of the reception of spectators to the cinema in the country, this research presents a deeper analysis of the reception of the public of the itinerant cinema as a contribution to an important database for the diagnosis of projects such as the Cine Sesi Cultural

Efeitos do treinamento aeróbio sobre sinais precoces do remodelamento do ventrículo esquerdo induzido pelo diabetes Mellitus experimental

Our aim was to investigate the effects of an aerobic training program on adverse and early left ventricle (LV) remodeling, using an experimental model of short-term type 1 diabetes (T1D). Wistar rats were divided in 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (SD) and trained diabetic (TD). T1D was induced by streptozotocin (45 mg/kg). The training program consisted of 4 weeks running on a treadmill (13 m/min, 60 min/day, 5 days/week). At the end of the experiments, hearts were collected for analysis of morphology and transcriptional profile of LV, by focusing on its remodeling. Deaths were recorded during the 4-week period. We verified high mortality among animals of DS group, whereas it was significantly reduced in DT group. DS group also showed an increase in cross-sectional area of cardiomyocytes and fibrosis. TD group exhibited reduction in measures of cardiac trophism, but with respect to collagen content, it was similar to CS group. Analysis of gene expression related to cardiac remodeling revealed decreased expression of collagen I and III, as well as low expression of MMP-2 in DS group. TD group showed decreased levels of mRNA for MMP-9, and unchanged gene expression of MMP-2 when compared with the CS group. The expression of MMP-2 and TGF-1 were increased in CT group. The ratio between gene expression of collagen I and III was increased in the CT group and decreased in diabetic groups. These results establish early changes of the structure and transcriptional profile of LV myocardium. Moreover, they indicate that aerobic exercise training plays specific protection against mechanisms responsible for cardiac damage observed in T1D

Alterações nos genes da E-caderina e β-catenina em adenoma pleomórfico e carcinoma adenóide cístico: estudo molecular e imuno-histoquímico

Pleomorphic adenoma and adenoid cystic carcinoma represent a benign and malignant salivary gland neoplasm, respectively, that shares the same histological origin, however with distinct biological behavior. The aim of the present study was identify the -160 C/A polymorphism in the gene CDH1, mutational analysis of CTNNB1 gene and evaluation the expression of the E-cadherin and β-catenin in pleomorphic adenomas and adenoid cystic carcinomas. Furthermore, it was proposed correlate the immunochemistry staining patterns with the polymorphism and mutations. Twenty-four pleomorphic adenomas and 24 adenoid cystic carcinomas were retrieved. The polymorphism analysis was performed by restriction fragment length polymorphism (RFLP), using the restriction enzymes HphI or AflIII and the mutational screening was performed by PCR-single strand conformational polymorphism (PCR-SSCP). The immunohistochemical analysis was taken by the counting of cells, recorded as the Hscore index, and considering the presence or absence, intensity, distribution and localization of proteins expression. Comparing the two neoplasms, the results demonstrated statistically significant difference for the E-cadherin and β-catenin expression, with pleomorphic adenoma presenting weaker immunostaining. Was observed statistical correlation between E-cadherin and β-catenin expression. CDH1 heterozigotic polymorphism was seen in two cases and 13 cases displayed abnormal mobility electrophoretic shifts, suggesting CTNNB1 gene mutation. The immunohistochemical expression was not statistically correlated with the polymorphism or suggested mutations. In conclusion this study supports that the E-cadherin/β-catenin complex immunohistochemical expression might be related with the myoepithelial component amount and differentiation neither the tumor biological behavior. The cases that showed E-cadherin gene polymorphism presented reduced protein expression and, moreover, CTNNB1 suggested mutations seem not influence in the β-catenin protein expression

O efeito da dessincronização circadiana sobre o metabolismo

The lost of phase relationship between rhythms and behaviour can, and often do, undesirable consequences. The purpose os study was to ascertain the effect of circadian desynchronization in T22 about metabolism of wistar rats. The subjects consisted of 24 animals separated in two groups: control (n=12) T24 with 8 weeks of aged and experimental group (n=12) T22, also with 8 weeks of aged. Both the groups were subject to register of locomotor actitivity, body temperature, body weight and food intake in all the experiment. And more, both the groups were subject to food deprivation, running in treadmill and forced swimming. The results show rhythm of locomotor activity and body temperature desynchronized. Dont exist diference in body weight between both the groups (T24 = 386,75±40,78g e T22 380,83±44,28g) . However, the food intake was different between the phases, light and dark, in intergroup and intragroup. The body temperature was not different in food deprivation. The same ocurred for running in treadmill and forced swimming. Since similar alterations occur in shift workers, it is proposed that the experimental paradigm presented in this manuscript is a useful model of shift work. That is, alterations in activity/rest cycles and consummatory behavior can affect the health of organism

Análises bromatológicas e fitoquímicas de frutos de Licania tomentosa (Benth) FRITSCH

This study conducted chemical analyzes of the fruits of Licania tomentosa Benth belonging to the Chrysobalanaceae family, order and superorder Rosiflorae Rosales. Samples were collected in February 2011 in the city of Natal - RN. The fruits were separated into peel, pulp and seed, and the samples were analyzed on moisture and ash by thermogravimetric methods, reducing and total sugars, lipids by Soxhlet extraction, minerals by ICP / OES and other analyzes by physical measurements of the fruit. The fruits for the analysis of determination of flavonoids and phenolic compounds were dried at 40 ° C and ground. For the analyzes to determine the content of phenolics and flavonols was used spectroscopy in the visible region, and also performed the characterization of ethanol extracts by high performance liquid chromatography and test for antioxidant activity hydroethanolic extracts. The results obtained are about 83.9% of the fruits have a length between 4.0 to 6.0 cm with respect to the diameter of the fruit about 97.4% of the fruits have a diameter between 2.0 - 4, 0 cm, mean weight of 36.14 g (7.86), the bark showed 60.5 (1.5)% relative humidity, the flesh 72.3 (0.9) and 44.4 seeds (0.4 )%, the bark showed 0.22 (0.00)% ash, the pulp 1.41 (0.01)% and the seed 1.18 (0.01)%, the bark showed 3.73 (0, 09) mg lipids / 100 g sample of the pulp 0.40 (0.04) and the seed 0.05 (0.00). With respect to reducing sugars and total gave the results, 16.23 (0.23) g/100g and 20.70 (0.24) g/100g. The fruit is presented with a good source of nutrients especially carbohydrates and lipids. The analysis for determining the antioxidant activity tests were performed reducing power and antioxidant capacity, the antioxidant capacity of hydroethanolic extracts of peel and pulp showed similar results, with higher concentrations however hydroethanolic bark extract. Regarding the content of phenolics and flavonoids hidroetanílico bark extract showed higher concentration values. The characterization of the extracts by high performance liquid chromatography identified the following compounds by retention time indicated by the race of the standards: galic acid, kaempferol and kaempferol derivatives. Considering the results of the fruit Licania tomentosa Benth may be an alternative food by analysis of their nutritional content and has substances with antioxidant action

As vidas e as mortes de Jararaca: narrações de uma devoção popular no Nordeste Brasileiro

Este artigo parte de um estudo etnográfico da devoção popular ao cangaceiro Jararaca em Mossoró, Rio Grande do Norte, morto pela polícia local em 1927. Seu objetivo é destacar os ritos que manifestam e suportam tal devoção, sobretudo em seus aspectos verbais: testemunhos, narrações hagiográficas e fatos históricos tidos como reais - principalmente os fatos que cercaram a morte do cangaceiro e suas proezas no cangaço - que dão margem à reelaboração da identidade social do morto, de modo a aproximar sua vida do modelo do Robin Hood, o bom bandido, e sua morte do modelo do martírio cristão. Assim, ele pode tornar-se um santo funerário.
