Production and Trade of Cambira Fish in Brazil
Adilson Anacleto, Alesandra Sopelsa, Greicy Ellen Lopes de Brito, Sebastião Cavalcanti Neto
Abstract Fishing on the Brazilian coast has been practiced for centuries. In Paraná Coast since the colonial period the technique of fish conservation denominated cambira was adopted, which consists in salting, drying and smoking the fish, technique that was passed from generation to generation until the nowadays. However, in the last decades the production and commerce of cambira has been reduced. Considering the importance of this activity for the cities in Paraná Coast and aiming to understand the reasons that led to the reduction of the production and trade of this delicacy, this study aimed to elaborate, in the perception of the producers, an overview regarding the production and trade of cambira evidencing the implications and socio-economic potential in the regional context. For this, an exploratory and descriptive research was carried out and, between July and November of 2018, it was accomplished face-to-face interviews with five cambira producers considered specialists in the activity. The study found that the producers were in average 62 years old, married, they practiced small-scale artisanal fishing, mostly incomplete elementary school (n = 80%) and produced the cambira for 30 years. The main species of fish used in the manufacture were mullet (Mugil brasiliensis), catfish (Bagre marinus), anchovy (Pomatomus saltator), mackerel (Scomberomorus cavala) and parati (Mugil curema). The main potentialities observed in the interviewees' perception were the alternative of family income obtained with this food production and trade, fish durability and the fact that the cambira is a typical and tasty dish from Paraná Coast, influencing even the regional tourism. The main implications observed were the decrease in family income with the low demand by the tourists for the delicacy, the difficulty of the producers in accessing the fairs for direct trade with the consumer and the lack of public power incentive in divulging the cambira in the regional events. It seems that the limiting factors could be mitigated as the entrepreneurial capacity of the families involved in the production and trade of cambira was strengthened, at the same time the collective organization should be raised, increasing the bargaining power with the public agencies, thus facilitating the opening of new marketing opportunities in fairs and events in Paraná Coast.

Analytical Methodology for Determination of the Plasma Antioxidant Capacity Through the Radical 2,2-azino-bis-3-ethylbenzthiazoline-6-sulfonic Acid (ABTS)
Aretuza Andrade Ferrante, Isabella Resende Martins, Luecya Alves de Carvalho Silva, Sandro Percário, Michelli Erica Souza Ferreira*
Abstract The method using 2,2-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid (ABTS) is currently used to access the total antioxidant capacity (TAA) of biological samples and is based on the production of its radicals through the reaction with an oxidant. Plasma is a biological matrix used in this method because it has several antioxidant molecules, including metal binding proteins, urate, bilirubin and superoxide dismutase. Nevertheless, it is important to know the limits of its application in the work environment. This knowledge is obtained through validation procedures aiming at characterizing methodological parameters, such as linearity, repeatability, limit of detection and quantification, precision, accuracy and robustness. The objective of this study is to evaluate the ability of ABTS method to access TAA, as well as to determine its reliably and methodological parameters. Plasma from 10 healthy volunteers aged 18-22 years were included in the study. The antioxidant activity was determined by ABTS method. The validation was performed following the recommended procedures. Determination coefficient was 0.9956. The limits of detection and quantification identified were, in sequence, 0.20 mM and 0.60 mM. The test showed accuracy of 107% (1.0 mM), 105% (1.5 mM) and 101% (2.0 mM). In the repeatability analysis, the coefficient of variation (CV), in the above concentrations, was 13.48; 7.61 and 5.29%; for intermediate precision were 13.58; 9.84 and 6.68%; and for robustness, were 10,24; 4.47 and 2.19%. The mean value of plasma antioxidant capacity was 2,05 mM. This study demonstrated that ABTS method had high reliability of application for quantification of total antioxidant activity in human plasma under protocol conditions. However, its methodological parameters should be tested for other biological matrix or, should procedure steps are changed.

Abstract Tourism in a region contributes to its economic growth by increasing the flow of people, heating trade and generating jobs in various sectors of the economy. However, accompanied by this growth there is also an increase in environmental degradation with the emergence of environmental impacts. Environmental impacts affect those who use the site, and a study of these impacts is necessary, in other words, an Environmental Impact Assessment. This study was carried out from July to September 2018, prior to any type of deforestation or construction in the area. The aim of this study was to identify and evaluate the possible environmental impacts generated in the construction and operation phases of the project, considering the physical, biological and anthropic environments. A Tourist Complex will be built, which will be located in the city of Pau dos Ferros, Rio Grande do Norte, Brazil. The methodology that was used is a combination of two methods of environmental impact assessment proposed in the literature, the checklist method and the Interaction Matrix method. The analysis of the impact matrix, related to the construction and operation of the Serrote do Jatobá Tourist Complex, reveals that the project should cause, in total, 133 significant environmental impacts in all its planned phases, 43 in the pre-implantation phase, 57 in the implantation phase and 33 when in operation. Of the total impacts counted, 66 were evaluated as positive and 67 as negative. Through the analysis of the collected information, it was identified that in the phase of implantation of the project the greatest environmental impacts are generated, but in the operation phase, the least adversities will be generated. When comparing the phase of operation with the other phases, it was verified that the adversities are not significant in all the evaluated environments. From these results, it was verified the great importance of the use of methods for the environmental impact assessment, because it made possible the anticipation of the impacts that the Serrote do Jatobá Tourist Complex can cause to the environment, before its implantation

Abstract (Homeopathic treatments and their effect on the initial development of cucumber plants grown in cow manure contaminated by auxinic herbicide). Homeopathy has been studied worldwide and its beneficial effects have been reported in animals and, more recently, in the healing of plants affected by various diseases, such as the treatment of plants grown on substrates contaminated with herbicide residues. However, information on the response of plants to homeopathic treatment is scarce. This work aimed to evaluate the neutralizing potential of homeopathic preparations on chemical residues of picloram + 2,4-D in bovine manure. After the herbicide contamination of manure, it was applied with each homeopathic treatment every 7 days, for a period of 10 weeks. The treatments consisted of the combination of three homeopathic preparations (Nux vomica, Carbo vegetabilis and Arsenicum album) and five dynamizations (6CH, 12CH, 18CH, 24CH and 30CH) and two controls = bovine manure without contamination and without homeopathic treatment; TH = contaminated bovine manure without homeopathic treatment). Samples were taken from each treatment for cucumber cultivation. On the 10th day after sowing, germination, emergence speed index, phytointoxication, aerial and root length and dry mass of the plants were evaluated. All homeopathic preparations worked positively to reduce the toxic effects of 2,4-D + picloram. However, they did not completely neutralize the action of the herbicide on early development of cucumber plants. Thus, it can be concluded that there is no differential response between homeopathic preparations and dynamizations between 6CH and 30CH in the expression of the toxic effect on young cucumber plants grown in manure contaminated with 2,4-D + picloram herbicide.

Abstract The state and the private market share the responsibilities of caring for the elderly with families. In this context, they are an alternative form of non-family care, Long-Term Care Institutions for the Elderly (ILPI), whether public or private. In this context, the objective of this study is to stimulate the development of social interaction activities among people living in a Long Stay Institution for the Elderly. Therefore, a qualitative, convergent study was carried out in the Community of Long-Term Care Institutions for the Elderly (ILPI), in Belém, northern Brazil, once a week, on Mondays, lasting 3 hours daily. Included in this study were elderly men, mean age 62.7 years, who performed approximately seven months of play activities that aimed to improve the autonomy of daily life activities, stimulating attention, memory, identity recovery and social interaction. The elderly was motivated and made available the activities proposed by the group, actively participating in all activities with enthusiasm. These activities were elaborated and performed at the ILPI, were in fact feasible to promote the health of the elderly, based on the postulates that support the strategies of play activities, considering the epidemiological and cultural reality of the elderly involved. In addition, we observed that play activities emerge as a technology that favors gerontological appropriation and is an adequate proposal to promote elderly health, since it provides a climate of motivation, interaction, relaxation and bonding (elderly-elderly, elderly-extensionist) and behavioral, becoming a facilitating tool for the care and promotion of active and healthy aging. Therefore, play activities are of great relevance for use with the elderly, and when used in ILPI are directly related to the health promotion of this population, providing very benefits. These benefits were evident during the performance of activities, such as interpersonal interaction, activation of cognitive and motivation. Therefore, the importance of the use of play strategies as a tool to promote improvements in the quality of life of institutionalized elderly people and the promotion of active and healthy aging should be reiterated.
