Revista Brasileira de Ecoturismo , 2012,
Abstract: O Estado do Amazonas possui uma das maiores biodiversidade preservada do planeta. Disp e de um banco genético precioso para a explora o científica e econ mica, porém, encontra-se amea ado pela degrada o ambiental. Por apresentar uma rica sociodiversidade com grande número de etnias indígenas, marcada pela cultura dos povos ribeirinhos, rica em festas folclóricas, a regi o também é conhecida como Referencial do Ecoturismo. O presente artigo se prop s analisar o impacto do polo ecoturístico no município de Iranduba/AM sobre as comunidades da regi o. A pesquisa é de natureza qualitativa, pois priorizou para a realiza o da coleta de dados a técnica metodológica do Grupo Focal. O que motivou a realiza o desse trabalho foi investigar o modus operandis do ecoturismo no Amazonas, com o fim de revelar se esta atividade tem sido realizada de acordo com o conceito defendido pela literatura. A escolha desse polo ecoturístico deu-se em virtude do município anteriormente citado abrigar a maior concentra o de hotéis de selva e uma diversidade de comunidades ao seu redor. O resultado do estudo aponta que as comunidades naquele polo est o excluídas do processo que constitui o tripé do ecoturismo, tanto com rela o ao equilíbrio ambiental, como o social e o econ mico. Verifica-se também a falta de consenso dentro do mercado turístico local sobre a importancia dos aspectos sociais e ambientais no setor. Com a realiza o desse estudo, espera-se contribuir com informa es básicas da realidade do mercado ecoturístico do estado do Amazonas para subsidiar constru o de políticas públicas na regi o Norte do Brazil. ABSTRACT The State of Amazonas has one of the largest preserved biodiversity on the planet. It has a valuable gene bank for scientific and economic exploration, however, which is threatened by environmental degradation. Due to its rich social diversity with a large number of indigenous ethnicities, which is marked by the culture of peoples on the riverside and rich in folkloric festivities, the region is also known as a Reference in Ecotourism. This paper aims at analyzing the impact of the Iranduba/AM ecotourism site on the local communities. Qualitative research using the Focal Group methodological technique was used for data collection. This work was carried out in order to investigate the modus operandi of ecotourism in the Amazon to show whether this activity is done in accordance with the concepts advocated in the literature. This ecotourism pole in Iranduba was chosen for its large concentration of jungle lodges and for the variety of its neighboring comm
Estudo da psico-manuten??o da Asma: as cogni??es como preditoras de emo??es e comportamentos problemáticos associados à Asma

Abstract: in a sample of 50 asthmatic patients, either hospitalised or outpatients, we studied the relationships between dysfunctional cognitions related to asthma and other psychological variables (emotions and behaviours) traditionally studied in cognitive-behaviour models, using specific measurement instruments of these variables for the asthmatic disease. the obtained results suggest that dysfunctional cognitions related to asthma are predictive of problematic behaviours/emotions that occur before, during and after asthmatic crises. they suggest that dysfunctional cognitions are predictive of higher “panic/fear” symptomatology and of more negative attitudes towards asthmatic disease and treatment.

Abstract: bronchial asthma is a complex disease and it brings limitations to patients' quality of life. in this research we intend to study the relationship of sociodemographic (gender, age and educational level), medical (severity of the disease, duration and clinical type) and psychological variables (cognitions, emotions and behaviour) with patients' quality of life. fifty asthmatic patients from the department of pulmonary medicine and immunoallergic diseases of coimbra's university hospitals completed five self-report questionnaires that measured the psychological variables under study. medical data were also collected. our results suggest that quality of life is related to a set of variables that can be named as biopsychosocial (e.g., a poor quality of life is related to a higher age, lower level of education, a more negative attitude towards asthma, named "stigma", disfunctional cognitions and behavioural/emotional problems associated to asthma). implications in relation with the treatment are also presented.

Abstract: samples of beer made in brazil were analyzed for the presence of fumonisin b1 (fb1) and ochratoxin a (ota). fb1 was searched for in 58 beer samples from 30 plants located in nine states. the samples were concentrated and cleaned up with strong ion exchange column, derivatized with opa and analyzed by hplc with fluorescence detection. the limit of detection was 0.26 ng.ml-1 and the average recovery was 98%. twenty-five samples contained fb1 ranging from 1 to 40 ng.ml-1. beer (123 samples) from 36 plants located in 5 states were analyzed for ota by means of immunoaffinity column cleanup followed by liquid chromatography associated with fluorescence. the detection limit was 0.1 ng.ml-1 and the average recovery was 92%. five samples contained ota in concentrations from 1 to 18 ng.ml-1. the results indicate that fb1 and ota contamination in brazilian beer is not geographically limited and that beer does not contribute significantly to fb1 intake by consumers. in the case of regular high ingestion, beer could contribute sizably to ota, intake although still below the maximum considered tolerable for the toxin.
Intoxica??o por larvas de Perreyia flavipes em bovinos na regi?o sul do Rio Grande do Sul

Abstract: three outbreaks of poisoning by perreyia flavipes konow, 1899 (hymenoptera: pergidae) in cattle during july and august 2006 in southern brazil are reported. the morbidity rate was 0.8%, 6.2% and 33% on the 3 farms, respectively. fatality rate was 100%. clinical signs were depression, jaundice, recumbence, pedaling movements and death in 24-48 hours. the liver was enlarged with increased lobular pattern, the mesenteric lymph nodes were edematous and peyer patches of the small gut were depressed. petechial hemorrhages and ecchymosis were observed in the mesentery and abomasum. on histologic examination the liver showed centrolobular or massive necrosis. hemosiderosis and necrosis of the germinative centers of lymph nodes, white pulp of the spleen and peyer patches were also observed. the poisoning occurred probably due to an intense drought in october-december 2005, when the insect stayed as a cocoon underground. the dry conditions probably avoided a higher number of adult sawflies to emerge from the cocoons, what resulted in greater egg production. the large amount of decaying grass due to almost normal rain fall during summer seemed to have provided favorable environmental conditions for the development of larvae in winter.

Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n2p281
Abstract: Lately, several studies have demonstrated the health benefits associated with natural compounds consumption. Fruit phenolics, lycopene and ascorbic acid, have strong antioxidant, anti-inflammatory, antimugenic and anticarcinogenic activities. In the present study parameters related to fruit quality and climacteric conditions, such as color, moisture, pH, water activity, total phenolic compounds, ascorbic acid and lycopene content were analyzed. Diospyros kaki cv. chocolate fruits were extracted with different solvents, such as methanol, ethanol and water. Total polyphenolics of each extract determined by Folin-Ciocalteu method were found to be higher in methanolic extract (106.2 mg/100g sample) and lower in ethanol (21.9 mg/100g sample) considering Diospyros fruits with peel. The antioxidant activity (AA) was evaluated by an in vitro model system trough 1,1-diphenyl-2-picrylhydrazyl radical scavenging capacity (DPPH ) assay. Significant variations were found in the levels of these parameters according to different geographic regions. It was possible to describe correlations between the antioxidant compounds (polyphenolics, ascorbic acid and lycopene) and the antioxidant activity. Aqueous solvent was more effective on the extraction of antioxidant compounds from Portuguese Diospyros fruits with 52% radical scavenging activity. Results support the importance of Diospyros kaki cv. chocolate fruits, Portuguese cultivar, as a functional food with high antioxidant potential that may have beneficial effects against oxidative human damage.

Abstract: this study evaluated the effect of water-bath and microwave post-polymerization treatments on the flexural strength and vickers hardness of four autopolymerizing reline resins (duraliner ii-d, kooliner-k, tokuso rebase fast-tr and ufi gel hard c-ugh) and one heat-polymerized acrylic resin (lucitone 550-l), processed using two polymerization cycles (short cycle - 90 minutes at 73oc and 100oc for 30 minutes; and long cycle - 9 hours at 71oc). for each material, thirty specimens (64 x 10 x 3.3 mm) were made and divided into 3 groups (n=10). specimens were tested after: processing (control group); water-bath at 55oc for 10 minutes (reline materials) or 60 minutes (l); and microwave irradiation. flexural strength tests were performed at a crosshead speed of 5 mm/min using a three-point bending device with a span of 50 mm. the flexural strengths values were calculated in mpa. one fragment of each specimen was submitted to vickers hardness test. data were analyzed by 2-way anova followed by tukey's hsd test (a=0.05). l microwaved specimens (short cycle) exhibited significantly higher flexural strength means than its respective control group (p<0.05). water-bath promoted a significant increase (p<0.05) in flexural strength of k and l (long cycle). the hardness of the tested materials was not influenced by the post-polymerization treatments. post-polymerization treatments could be used to improve the flexural strength of some materials tested.

Abstract: introduction: the hardness of denture base materials may undergo changes due to continued polymerization reaction and water uptake. however, the extent to which these processes affect the hardness of materials is still unclear. objective: in this study, the degree of conversion of two hard chair-side reline resins (duraliner ii-d and kooliner-k) and one heat-cured acrylic resin (lucitone 550-l) was evaluated indirectly by measuring the surface hardness. the effect of immersion in water on this property was also analyzed. materials and methods: after processing following the manufacturers' instructions, specimens (5mm diameter and 2mm thickness) were dry stored at room temperature and the vickers hardness (vhn) was measured with a hardness tester after 0, 2, 7, 30 and 90 days. specimens were then immersed in water at 37oc and hardness was evaluated after the same time intervals. five specimens were prepared for each material. data were analyzed by kruskal-wallis test (p=.01). results: when dry stored, material l showed an increase in hardness (p<.01) from 0-day (vhn=23.2) to 30-day (vhn=27.1), after which no significant change was observed. a continuous increase in hardness was observed for material d from 0-day (vhn=4.6) to 90-day dry storage (vhn=7.3). for material k, an increase in hardness was observed up to 7-day (vhn=9.2), and then leveled off (p>.01). after 2-day water storage, all materials showed a significant reduction in hardness (p<.01). conclusion: in general, the hardness of the materials evaluated increased during dry storage and decreased after immersion in water.

Abstract: purpose: this study assessed the shear bond strength of 4 hard chairside reline resins (kooliner, tokuso rebase fast, duraliner ii, ufi gel hard) to a rapid polymerizing denture base resin (qc-20) processed using 2 polymerization cycles (a or b), before and after thermal cycling. materials and methods: cylinders (3.5 mm x 5.0 mm) of the reline resins were bonded to cylinders of qc-20 polymerized using cycle a (boiling water-20 minutes) or b (boiling water; remove heat-20 minutes; boiling water-20 minutes). for each reline resin/polymerization cycle combination, 10 specimens (groups cat e cbt) were thermally cycled (5 and 55 oc; dwell time 30 seconds; 2,000 cycles); the other 10 were tested without thermal cycling (groups cawt ad cbwt). shear bond tests (0.5 mm/min) were performed on the specimens and the failure mode was assessed. data were analyzed by 3-way anova and newman-keuls post-hoc test (a=.05). results: qc-20 resin demonstrated the lowest bond strengths among the reline materials (p<.05) and mainly failed cohesively. overall, the bond strength of the hard chairside reline resins were similar (10.09±1.40 to 15.17±1.73 mpa) and most of the failures were adhesive/cohesive (mixed mode). however, ufi gel hard bonded to qc-20 polymerized using cycle a and not thermally cycled showed the highest bond strength (p<.001). when tokuso rebase fast and duraliner ii were bonded to qc-20 resin polymerized using cycle a, the bond strength was increased (p=.043) after thermal cycling. conclusions: qc-20 displayed the lowest bond strength values in all groups. in general, the bond strengths of the hard chairside reline resins were comparable and not affected by polymerization cycle of qc-20 resin and thermal cycling.
