Abstract: the barbatim?o is a tree which bark is rich in tannin. it is used on popular medicine as a wound healing agent, in the treatment of gastric lesions, as anti-leishmanial agent and as anti-inflammatory. red blood cells (rbc) are labeled with technetium-99m (tc-99m) and are utilized in many procedures in nuclear medicine. some authors have reported that drugs (natural and synthetic) can alter the labeling of rbc with tc-99m. this study evaluates the effect of barbatim?o infusion on the labeling of red blood cells (rbc) and plasma (p) proteins with tc-99m. heparinized blood from wistar rats was incubated with nacl 0.9% as control and different concentrations of barbatim?o infusion. following the addition of stannous chloride (sncl2), as reducing agent, and tc-99m, as sodium pertechnetate, the blood samples were centrifuged. p and rbc were separated and were also precipitated with trichloroacetic acid 5%. insoluble (if-p and if-rbc) fractions were isolated. the percentage of radioactivity in all the samples was determined. all the barbatim?o infusion concentrations decreased the labeling of rbc, if-p and if-rbc. we can speculate that the barbatim?o infusion interfered on the labeling of rbc due to the redox properties and/or it can also act as a chelator of the stannous ion.

Proposal of a Methodology for the Assessment of Security Levels of IoT Wireless Sensor Networks in Nuclear Environments  [PDF]
Marcia Maria Savoine, Mario Olimpio de Menezes, Delvonei Alves de Andrade
World Journal of Nuclear Science and Technology (WJNST) , 2018, DOI: 10.4236/wjnst.2018.82008
Abstract: The use of Wireless Sensor Networks (WSN) associated with the reality of an Internet of Things (IoT) scenario in nuclear environments is a growing security concern. In this context, standards are intensified to preserve the physical integrity of these facilities considered to be highly critical due to the size of the impacts of safety accidents. This paper presents a proposal to build a methodology to evaluate the security levels of WSNs with IoT devices when used in nuclear areas. The proposal is initially based on related work to establish a more concrete initial framework and is structured in consistent steps from previous scientific studies.

Abstract: the objective of this work is to determine the social behaviour concerning the consumption of vegetal species by local communities. the involved localities are: the usina s?o josé (igarassu - ig), which involves rural communities in the surroundings of the ecological reserve of the usina s?o josé and the jaguarana (paulista - pe), an urban settlement located in the neighbourhoods of the ecological reserve of jaguarana. structured interviews were applied to these social groups, addressing 38 people, in order to identify the most useful plants and the correspondent use. these were classified into categories food, commerce, constrution, ritualistic, medicinal, technological and "others". among these types, 334 native and introduced species were registered. the different communities were analysed and compared through the s?rensen similarity quotient (qs). the higher incidence is of feeding plants (qsigpa= 0.71), predominantly cropped and medical plants (qsigpa= 0.56), from which 45.1% are natives and herbaceous. the native vegetation constitutes an important source of medicines. however, it has no relevance as food within the cosmological view of the community. vegetables are irrelevant as timber in the trade sector, for income generation (qsigpa= 0.30). for building proposals most species are native (87.8%) and tree (92.7%). for technological purpose the native species (85.7%) and the tree/shrub (84.1%), are the most representative category. the communities use different types of vegetal resource for the construction, ritualistic and technology among other categories, as a result of their main activities and of the available natural resources.
The cultural significance of plants of the Pernambuco indians: The Xucuru case
Valdeline Atanazio da Silva,Laise de Holanda Cavalcanti Andrade
Biotemas , 2004,
Abstract: The Index of Cultural Significance (ICS) created at the end of the 1980′s, aims to register the value of each vegetable species and to disclose its importance for the biological and cultural survival of a traditional community. Initially, the ISC was considered and applied in aboriginal communities in Canada and the United States. Aiming to verify its applicability for Brazilian aboriginal groups, it was used in the present work to evaluate the cultural meaning of the useful species for the Xucuru tribe, in pesqueira county, Pernambuco. In Brazil, it is the first time that this index has been used with a northeastern aboriginal community, the Xucuru, one of the seven tribes remaining in Pernambuco. From informal interviews, 97 useful species were registered among trees, shrubs and grass growing in the Pedra D’água forest (Humid Ororobá-Forest), in yards, and in small cultivated areas in the village. The ISC provided a numeric order of importance for the plants registered in the Xucuru tribe, much like the one observed in the field. Musa paradisiaca was the species of greatest meaning for the community (ICS 120), followed by Rosmarinum officinalis (ICS 92), Xerophyta plicata (ICS 88), Aspidosperma sp. (ICS 84) and Cymbopogon citratus (ISC 80). The place of distinct prominence for non-native species of the area (exotic) evidences the importance that such species have acquired in the Xucuru culture.
A New Biomaterial for Urinary Catheters  [PDF]
Roberto Santos Lima, Salvador Vilar Correia Lima, José Lamartine De Andrade Aguiar, Eziel Cavalcanti Vasconcelos Rocha, Flávia Cristina Morone Pinto
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2018, DOI: 10.4236/jbnb.2018.91001
Abstract: Several studies argue that an ideal biomaterial for urinary catheters is utopian. Based in literature review it seems to be true. However, research advances: the biomaterial itself, new designs, new coatings, associated drugs, etc. Once implanted and interacting with urine, two old problems persist: encrustation and bacterial colonization. In this context, an extracellular product from bacterial synthesis on sugarcane molasses biomaterial has been studied in several experimental and clinical studies. Based on its high biocompatibility, the aim of this study is to evaluate its performance in an in vivo model as an endourologic prosthesis implanted in the bladder of Wistar rats. We evaluate physical, chemical and biological phenomena in comparison to an already established biomaterial, polyurethane. Even though it is not a finished product, the sugarcane biopolymer presented similar performance compared to polyurethane in several analyzed parameters and has an important characteristic: low cost.
