The development of new materials has been a major focus of modern science. In order to obtain materials with desired features, studies about synthesis are necessary for a better understanding of their synthetic processes. In this light and in search for new materials in heterogeneous photocatalysis, a challenge is to understand the synthetic processes by the investigation of synthesis variables. Thus, this thesis presents the synthesis of Ti oxide nanostructures (pure or associated with Sn oxide) through the alkaline hydrothermal method. Some variables such as precursor, base concentration, temperature and time of hydrothermal treatment were studied. In the syntheses of co-precipitated Ti and Sn oxides, the formation of Sn oxide occurred only under mild alkaline conditions, since high alkalinity caused the Sn dissolution. In the evaluation of precursor type, peroxytitanium complexes (PTCs) showed excellent characteristics to obtain titanate phases in mild alkaline conditions, since the process of titanate formation from PTC occurred without the complete degradation of its initial structure. In the study about temperature and time of synthesis, the temperature of hydrothermal treatment was the most important synthetic parameter. With respect to the photocatalytic tests of synthesized materials, the crystalline phase was the most important factor. The titanates showed higher specific surface area and higher concentration of hydroxyl groups, whereas the photoactivities were lower. The low photoactivities of titanates were attributed to the majority presence of fivecoordinated titanium species (TiO5). In this study, the hexa-coordinated titanium (TiO6) was considered the main active site for photocatalytic processes.

In a society governed by consumption, the desire for beauty is linked to the concepts of contemporary history; this concept has been transformed into a variety of beauty products for fitness and body available on store shelves, designed to help achieve these standards of beauty; people experience pressure to fit into the social ideals of beauty and they are affected both physically and psychologically; the promotion of these ideologies remains a powerful predictor of consumption patterns of individuals with respect to goods, services and products; the perception of beauty is not only determined by the outcome of genetic or biological processes but is also the privileged access to these resources. This exacerbated concern about physical beauty is evidenced in most physical activities, as they allow for a clear perception of body shape. Given that the learning processes in congenitally blind people are different from those who have visual sensations, there was a concern about that, in a world governed essentially by visual shapes and formulated conceptions, people with blindness could show concepts about beauty, rejecting or accepting the standards / models of beauty historically accepted and validated. Thus, this qualitative and descriptive study was aimed at investigating and understanding the social definition of beauty from the perceptions of people with congenital blindness; and, moreover, this article explains, discusses and examines the effects of these perceptions and evaluations of the other person in terms of physical attributes among individuals related to the social environment, from the own voices of these teenagers. A structured interview was adopted to gather data, which were recorded and transcribed in full and allowed for the qualitative analysis of the entire contents through content analysis. A study was carried out in cooperation with two Regional Boards of Education in the central region of the State of São Paulo and three teenagers with congenital blindness enrolled in high school were selected. The results pointed out the generalized and sublimated way that beauty is seized, internalized and recognized by blind people through the day-to-day practices. Goodness, kindness, gentleness, serenity, respect, courtesy, tenderness, and other moral, social and ethical characteristics were materialized in the beauty, suggesting a positive correlation between beauty and goodness and / or what is good. Voice perception is especially important for blind individuals in allowing them to recognize other people and their aims, and also enable them to evaluate their beauty. Other personal items such as clothing, perfume and personal hygiene practices were also regarded, to a lesser degree, as important items and components to help define beauty. One can find that there is a dissociation between beauty and body, so that the recent (but not so new) phenomenon of the cult of the body, when people make efforts to get in shape and achieve a vigorous, young, toned, symmetrical body, seems not to permeate the senses about ideas, behaviors and perspectives of people with blindness. Finally, language plays important roles in defining body as the image that an individual has of his or her body and other people s bodies, and is likewise used to create symbols, meanings and definitions of beauty, especially in situations where tactile exploration is not possible or allowed, as is the case of another person s body.

Objective: To evaluate the chondrocytes apoptosis by caspase 3 expression and its relation with the knee articular cartilage thickness and cellularity, at the acute phase after anterior cruciate ligament (ACL) transection, as the experimental model of osteoarthritis (OA). Material and Methods: Seventy two male Wistars rats were divided into 3 groups: ACL transection group (ACLT); control group (C); and sham group (S). Each group was subdivided into 4 subgroups: 24h, 48h, 72h and 1 week, according to the period following the procedures performed. The medial condiles of the left knees were processed in paraffin and stained with HE for cartilage thickness and cellularity analysis, by morphometry. Caspase 3 expression was evaluated through immunohistochemical method. Statistical analysis was performed by using the Kolmogorov-Smirnov test to assess the normality of the data, and then ANOVA with post hoc Duncan. Results: There was no statistical difference for articular cartilage thickness and cellularity between the groups. Regarding the caspase 3 expression, the C had smaller expression than the other groups. The ACLT 24h and ACLT 48h groups had increased expression of caspase-3 than their respective C and S. The ACLT 72h was not different from S 72h, and presented a lower caspase 3 expression compared to the other groups. The ACLT 7days and S 7days groups had higher expression than any other group. Conclusion: The chondrocyte apoptosis present since the OA beginning, using the ACL transection model of OA, however the articular cartilage thickness and cellularity changes can be modified at a later stage.

This work recovers the author s effective practice as the pedagogical coordinator in a school where booklets are used in its teaching system. The coordination happened during the school year of 2010 and the first semestre in 2011. There was not, initially, any pretension of transforming the effective professional activity into an object of analysis and reflection. As a result, the recovery of developed actions was made later through narrative, recovery of documents and interviews with the teachers involved in the process. Transforming one s own experience into an object of study has placed forward two methodological issues: the action research and the narrative investigation. There are things put into action, there is rememoration of action. This work crosses paths with the methodological investigation of both perspectives. The professional work had two great thinkers as references: Freinet and Bakhtin. The invariables and the Freinetian pedagogical instruments were recalled in the exposition due to their key role in the professional activity which was developed and analysed; the dialogic principles and the principles of the relationship with the alterity as a constituent form of the subjectivities have oriented the relationships with the teachers who participated in the research. For that reason they were recalled as a theoretical basis for the work. The look based on those two authors allowed the researcher to find the existing gaps in a school where bookets were used for pedagogical actions distinct from those expected by the system. Other possibilities of work in the classroom and at school were gradually built during the mentioned period by the author, who chose to do so instead of exercising the role of coordinator within the predicted limits of activity control. The actions with two teachers from the second year of the fundamental level (with children in the process of alphabetization) are related and analysed showing a recalling process by the teachers in their pedagogical practice. This, however, crucially depends on concrete support in other possibilities of action, which leads to the conclusion that the teacher only faces the challenge when he feels his feet are on solid ground, a motto of Freinet s pedagogy. Building an environment of transition with feet on solid ground was the task of the pedagogical coordination which demanded from the professional the exercise of a job pedagogically supported by a conception of education in order to supply students and teachers with bases for their highest , though somehow uncertain, expectations.

This study has the aim to analyze, from numerical analysis in finite elements, the behavior of masonry walls of bricks and closing blocks together with structural elements of reinforced concrete, in situations in which masonry and concrete collaborate in the support of the building. The analysis were made based on the diagram of tensions, where it was possible to observe the places with concentration of tensions and their form of distribution, and the parameters with influence on the behavior of the structure. On this analysis, several parameters involved in the composite systems of reinforced concrete and masonry were studied: the modulus of longitudinal deformation of the masonry; the presence and dimension of cracks, lintels and sills, beams and pillars; and models with ideal ties and where the walls join. Besides this, preliminary design of the concrete structure and masonry was carried out. The results of the analysis indicated that the presence of concrete elements together with the masonry results in a more uniform distribution of the tensions, besides having been observed a reduction of 50% in the compression tensions at the bottom of the wall for the model with concrete pillars. It was also verified that in the complete model, with pillars and beams, the beam presents a different behavior from a reticulated structure, indicating that the wall ends up serving it as a distributed support. In the preliminary design, it was noted that, without pillars and beam, the required resistance of the prism is compatible only for structural components. But in the case of beam, besides observing the difference among the models of calculation used and the real behavior of the structure, this element may not present the resistance and/or necessary security for the hypothesis of simply supported beam for the conditions that were admitted here. Regarding this study, it is important to emphasize that there is no intention of defending this type of structure, but rather analyse how it behaves before the actions.

Eosinophils are a hematopoietic cell originated from precursor cells found in bone marrow, whose differentiation and proliferation is regulated by cytokines such as GM-CSF, IL-3 and IL-5. When activated, eosinophils are capable of phagocytosis of small particles and bacteria, but their main form of activity in the inflammatory process is the release of toxic proteins, cytokines, enzymes, lipid mediators and reactive oxygen products. The increase in eosinophil is an important feature in many diseases such as allergy and parasitic infections. Provided APC (Antigen-Presenting Cells), eosinophils are considered similar to the CD (Dendritic Cells) in its potential to activate naïve T cells and may have potential as efficient as the CD in stimulating lung T cells in the upper airways in the model inflammation. The APC are defined by being able to take, processing and presenting antigen such as CD, macrophages, B lymphocytes and possibly eosinophils. The surface expression of APC is characterized by coestimatórias molecules CD80 (B7-1) and CD86 (B7-2) and also by MHCII. The proposed model for this evaluation was to Visceral Larva Migrans syndrome (VLMS) caused by Toxocara canis, one of the most frequent helminth in young dogs. One of the main consequences of this infection is the marked increase in circulating and tissue eosinophils. Eosinophilia has been associated with parasitic diseases particularly when the parasite invades or promotes tissue damage at mucosal surfaces In the present study we evaluated the expression of MHC II and CD80 and CD86 molecules coestimulatórias in eosinophils in VLMS. Our results showed that the molecules studied were expressed in eosinophils in the blood of mice infected with Toxocara canis compared with the control group. Correlating an intense eosinophil still during the course of the disease with increased IL-5 in the infected group. Suggests that during the course of Toxocara canis, eosinophils can exhibit behavior of an APC, increasing the expression of MHCII molecules coestimulatorias and possibily amplifyng the immune response in this model.

Background: Six minute Step Test, like other clinical exercise test is an important tool to evaluate the physical capacity, as being simpler and less expensive, however it doesn t have reference values and its reproducibility wasn t evaluated in apparently healthy population. Objectives: The objective of this study was to determine the reproducibility of the test in apparently healthy population and develop an equation to predict reference values for the Brazilian population. Methods: apparently healthy individuals, older than 18 years, were evaluated for anthropometry, body composition, lung function, physical activity level, it was conducted two step test and two Six Minute Walk Test. We investigated the relationship between the demographic and anthropometric findings and with performance in the clinical exercise tests. The reproducibility was assessed by intraclass correlation coefficient and standard error of measurement. It was used the stepwise method, in the multiple regression analysis, to develop an equation model to predict reference values. Results: 91 subjects (40 men) were included in this study, with an average performance in the first and second test step of 134 steps. Correlations were found between the Step Test and age, height, length of lower limbs and body fat percentage. The two clinical exercise tests were excellently reproducible, with ICI> 0.8. We developed a regression equation (p <0.05 and R ² = 0.5): Six Minute Step Test=348.4 + 48.48 x Gender (male = 1, female = 0) -1.29 Age(years) -0, 98xHeigth (cm). Conclusions: The test step is reproducible in apparently healthy individuals and there is a relationship with height, age and gender thar can predict reference values for the Brazilian population

Cet article a comme objectif présenter une discussion sur la nature de la notion de la base du pensement cartésien: le cogito. En étudiant la nature du cogito comme une substance qui pense on a l intention de montrer l importance du sujet qui se dégage de ce premier principe méthaphysique à l établissement d une science indubitable. Pour cette raison, en considérant le chemin réflexif par Descartes dans ses Méditations Métaphysique, nous essayerons montrer que la notion de subjectivité est cruciale pour la compréhension de la relation de la Métaphysique, comme compris par Descartes, et la nouvelle épistémologie qui se dessine dans la modernité, sûrement que la participation du sujet de la connaissance dans la consolidation de la science universelle ne se résume que d en être une première vérité. Comme nous savons, on commence dans l environement de celle subjectivité ci aux moments justes du système cartésien pour élaborer sa épistémologie, mais en assurant à l interieur les conditions pour la consolidation de la certitude, le sujet augmente son importance et, dans le processus d auto-validation, il vient de participer activement dans la fondamentation de la connaissance. Le sujet de la connaissance, s il ne peut pas être consideré la base dernière de la vérité, constitui au moins une première base du principe d évidence sans lequel aucune vérité, au delà des limites de sujet, est possible d être atteinte.

The aim of the thesis was to evaluate different strategies for correcting spectral and non-spectral interferences on As and Se determination by inductively coupled plasma optical emission spectrometry (ICP OES) and mass spectrometry (ICP-MS) techniques. The determination of 75As+ and 80Se+ isotopes by ICP-MS is strongly affected by the presence of 40Ar35Cl+ and 40Ar2 +, respectively. These interferences can be solved using strategies of sample preparation, cool plasma and more recently collisions and reactions cells. It was studied here a new device for correcting those spectral interferences by the introduction of H2 and He gases through the sampler and skimmer cones present in the collision reaction interface (CRI). The introduction of H2 gas through the skimmer cone was more efficient for destroying polyatomic ions. Lower limits of detection (LOD), 0.019 and 0.097 ng mL-1 for 75As+ and 80 Se+ isotopes, respectively, were obtained by adding 80 mL min-1 H2 through the skimmer cone. The accuracy was demonstrated using two certified reference materials oyster tissue and mussel tissue. Matrix effects may also be corrected using suitable calibration strategies, such as internal standard or the standard additions method. For determination of As and Se by ICP OES it was evaluated a new nebulizer named FB®MN to correct matrix effects and to reduce interferences applying on-line calibration strategies. The aerosol generated by FB®MN was characterized and compared with the aerosol generated by a conventional pneumatic nebulizer (Micromist®). Solutions containing 0.05 and 0.10 mol L-1 Na, K, Ca, Mg, or a mixture of them were used as synthetic matrices. Germanium, In and Y were tested as internal standards. Best recoveries were achieved when 1 mg L-1 of In was used as internal standard. The values of D3,2 and D50 parameters demonstrated that the aerosol produced by using FB®MN has smaller drops than the aerosol produced by using Micromist®. In this study the FB®MN was also used for generation of As and Se XV hydrides directly into the aerosol formed inside the nebulization chamber before detection by ICP OES. The FB®MN allowed the hydrides generation directly into the spray chamber without using any additional device either for solution and gases control or for gas phase separation. Synthetic solutions containing As and Se plus Ca, Mg and K were used for evaluating hydride generation. Germanium, In and Y were tested as internal standards. Accuracy was assessed using addition-recovery experiments in synthetic solutions. Best recoveries for all media were achieved when Ge was used as internal standard. Limits of detection (LOD, 3σ blank) of 2.7 and 5.8 μg L-1 were obtained for As (228.812 nm) and Se (196.016 nm), respectively, when keeping the nebulization gas flow rate at 0.6 L min-1 and the liquid flow rate at 0.67 mL min-1.

Compare the values predicted by three equations referenced in the literature with the values obtained by our sample of healthy volunteers in the six minute walk test (6MWT), and establish a new reference equation for 6MWT for the Brazilian population. 89 volunteers were evaluated (43 women) 37.8 ± 15.9 years old by spirometry, assessment of physical activity level by the International Physical Activity Questionnaire (IPAQ) and performed two 6MWT with rest intervals of 30 minutes between tests. For comparison the greatest distance achieved during the 6MWT (WD-6MWT) to the equations provided we used the Friedman test with post hoc Dunn and the correlation of variables with the WD-6MWT Spearman's test and the predictive model was performed multiple linear regression analysis by stepwise method. European equation significantly overestimated (p <0.001) WD-6MWT, Brazilian and American underestimated showed no significant difference. The WD-6MWT correlated significantly with gender (r = 0.46), age (r =- 0.59), height (r = 0.57) and length of the lower limb (LL-C) (r = 0.59). The reference equation was developed WD-6MWT= 401.185 - (2.402 x age years) + (43.247 x gender 1 = male, female = 0) + (1.757 x height cm). Therefore, in view of the results obtained, it was possible to predict a new reference equation for Brazilian individuals, which explained 60% of the total variability in 6MWT, and will certainly contribute to improve the interpretation of the exercise capacity of patients with functional disability.

This work consists on the preparation and characterization of the optical, thermal and structural properties of glasses and nano-glass-ceramics based on heavy metal oxide glasses, containing different transition metal elements (Ni and Ag). We studied the follow vitreous compositions: 100-x(30SbPO4-50WO3-20PbO)-xNiCl2 (x= 0 - 10 % mol) and 100-x(SbPO4-WO3-PbO-4NiCl2)-xAgCl (x= 0 - 20 % mol). The glasses were prepared in platinum crucibles using the melting-quenching methodology. Thermal characterization was carried out using DSC technique, while the structural characterization was done using the X-ray diffraction, Infrared, and Raman spectroscopy. Optical properties were determined using UV-Vis, luminescence, Zscan and M-lines spectroscopy. Chemical analysis and the morphology of nanoparticles were studied by EDX and transmission electron microscopy, respectively. In order to induce controlled crystallization into the glassy matrix, heat treatments above Tg in both vitreous systems were performed. Samples containing only nickel have been studied by Luminescence and Z-Scan techniques to study the emission in the near infrared region and determine the nonlinear refractive index, respectively. Luminescence results obtained for the system 100-x(SbPO4-WO3-PbO)- xNiCl2 show infrared broad band emission into the range from 1.2 to 1.8 µm arising from Ni2+ transition in octahedral sites. Controlled thermal annealing leads to formation of NiO nanoparticles. Samples in the system 100-x(SbPO4-WO3-PbO- 4NiCl2)-xAgCl, when submitted to thermal annealing leads to crystallization of metallic silver nanoparticles with different sizes which is depending on the time of treatment. No changes in the optical spectra, concerning the Ni2+ transition were observed after thermal treatment.

The problem of solid waste has been touted as one of the most serious to date. The increasing scarcity of land for the establishment of new landfills, combined with the existing limitations for the recovery of non-renewable materials, low degree of implementation of new treatment alternatives and recycling, now represent a major challenge. Therefore, considering the fact that we live in a capitalist society which has its economy based heavily on high productivity, had a reduction in turnover time of consumption and, consequently, a decreased half-life of the product, for encouraging statistics increasing consumption and disposal. This research, interdisciplinary, theoretical aspects of the field allied Science, Technology and Society (STS) and Sociology of Consumption by one of the methodologies of information science. Aimed to provide an assessment of trends through patent documents, through monitoring of technological products and processes related to waste disposal technology in the patent database Esp@cenet free online, through the development of a method own analysis of the contents of patents. The specific objectives were: a) identify and categorize the types of materials classified as technological waste; b) to detect what types of materials with this classification exists in Brazil, disposal policies; c) develop methodology for gathering and analysis to evaluate trends found in patent documents through content analysis, d) to compare trends in patent documents raised with the current situation prevailing in the Brazilian legislation on waste disposal technology. The methodology was qualitative and quantitative character descriptive and exploratory, the theme for the characterization and description of the universe to be studied. As an instrument of data collection, made use of technological monitoring in databases of patents, and as a means of data analysis, content analysis. The analysis was made within the principles of the STS field that seeks to build an economically stable, environmentally sound and socially just, with which he was expected to contribute and encourage interaction among studies in the area of Intellectual Property with the studies STS field and the issue of environmental sustainability. How results revealed stark contrasts in claims purely technical document that took into account more than just a summary description of the technology in question, but also with aspects of the socio-economic sustainability and environmental. Through the study of classifications more common in the universe and study the applications presented in the documents, it was possible to categorize the universe of technologies: 1) methods/processes for separation of plastics contained in electronic scrap; 2) methods/processes for metal separation noble; 3) containers for packing and safe transportation of WEEE; 4) other technologies not directly related to the theme studied. It was concluded that universities, government and society as a whole must unite so that new practices are environmentally sound world created and adopted so that the impact has already generated is reversed, or in a more realistic view that new impacts not or are generated, only minimized.

The present study has for objective to identify effects of the productive reorganization in the work of truck drivers, in the period between 1980 and 1990 in Brazil. This research is a study of case about two companies of road haulage (RH), with tradition in the segment. They had been selected on the basis of the time of performance in the market, regions of operation and localization of the company. Following criteria defined previously, involving mainly the work time, drivers (salary earning and aggregate) and managers of different areas had been interviewed with a focus on trajectory of work within the company. Beyond the study of case, the bibliographical research on the history of the RH in Brazil contributed to understand the moment the road haulage becames predominant in the country and why. The results show that, historically, the road transport always was connected to the industrial sector and that the changes in the management of the production of this sector had direct impact in the management of the transports. Thus, since the 1990s, the transporters have increased the agility of the process of transport, reduced costs and time spent, guaranteeing the quality of the services given through the use of concepts and practices linked to Suplly Chain Management (SCM) and Logistics. New practices in an old labor model: new employment contracts to reduce costs and avoid the limitations of labor law (outsourcing), extension of working hours and remuneration for productivity (to drive more is to earn more). The absence of an adequate legislation that regulates the activities of the RH and imposes limits to the drive time and distinguishes it and the work time, equally contributes to the long labor journey to become one more factor of risk in this profession, especially between the drivers who work with fast orders lines.

Daily life has been a subject of interest for specialists of several areas of knowledge, with different purposes. The increasing valorization of this theme reflected in different kinds of theoretical studies and theories because of its relevance. Considering the complexity in the (re)construction process of daily life, the occupational therapist should have a more precise monitoring about the organization of the activities and the assessment process. It is necessary to take care of the individual s place and satisfaction on this organization. People with development disorders have their daily life altered. This happens to children suffering from cerebral palsy. The objective of this study is to describe and compare the daily life aspects of 19 children with cerebral palsy and 19 children who have typical development, related by the children s routine, leisure, personal care, school and , educational and therapeutic activities. To achieve this goal, a general description of every child was made according to data obtained at interviews and the use of an Activities Clock used by the organizers (the goal was to investigate how the child s daily life is organized). According to the results obtained it is possible to verify that the children with cerebral palsy have more dependency in day life activities, lesser diversity of companion, lesser diversity of places to go and lesser leisure, when compared to children with typical development. The obtained results presented and discussed in this study could contribute in increasing the knowledge about the daily life of children with or without deficiencies, their main similarities and differences, as well as in pointing to new researches that are needed within this area.

It is known by the entire scientific community the recommendations of the World Health Organization (WHO) on breastfeeding, ie, all babies should be breastfed exclusively with breast milk from birth to age six months and after this period, children should continue to be breastfed, along with complementary foods up to two years or more. However, research confirms that Brazil is still below the level recommended by WHO, ie, we have in alarming prevalence of early weaning in our capitals and the Federal District.Thus, early weaning is the focus of our study, being considered as the complete interruption of breastfeeding before six months of baby's life. The aim of this study was to identify with women who weaned their children early, transformers and exclusores aspects of breastfeeding and early weaning. The theoretical and methodological framework was composed of Dialogic Learning, Feminism and Methodology Dialogical Communicative Critique. This is a qualitative study, conducted in various districts of the city of Itirapina / SP in the period 2010 to 2011. Participants were 12 mothers who weaned their children early, before six months old infant and has not passed three months of weaning due to possible oblivion information. Data were collected from questionnaires, interviews, field diary and discussion group communication. The socioeconomic profile of the mothers collected from questionnaires were analyzed using the program Microsoft Office Excel 2007 and qualitative data from the basic level of analysis proposed by the Communicative Method, pointing out the aspects transformers and obstacles in the experience of breastfeeding and weaning early. The socioeconomic profile of the mothers were: young people, aged 20-29 years, married (42%), the majority had completed secondary technical education (59%), most of the mothers worked outside the home (67%) and were primiparous (75%). The qualitative results allow us to conclude that maternal employment and labor laws were exclusores factors, the understanding that the nipple protrusion is essential for breastfeeding was also an aspect exclusor, but it deserves further study. The identification of increased financial expenses of the family with weaning was transformative capacity for reflection and highlights of the mothers, breastfeeding is a practice socialized since childhood highlights the biological character, but the affinity for the breastfeeding rescues the right to make choices and be respected for being different. The pleasure in breastfeeding was the function of being submissive mother and give up this feeling and "take the pain" for the health of the child. Such perceptions make us reflect how society loses by not listening, silence voices and even judge the proposals of the mothers rather than trying to make sense of them.

This methodological study aimed to develop and validate educational material and illustrative writing for men with urinary indwelling catheters at home. We conducted a literature review on guidelines related to the theme proposed for the content of the material. Nineteen articles were included in the review, fourteen studies selected from PubMed, CINAHL and 2 in 3 in LILACS. It was used as theoretical framework health literacy and health education and as methodological framework, the model of content validation of diagnostic proposed by Fehring (1987) and the assessment of the Suitability assessment of educational materials. The educational material consists of a brief introduction entitled Catheter care at home, and 32 guidelines organized into 10 thematic categories: body care, urinary catheter care and the collection bag, emptying the collection bag, when I should use gloves, fixing probe, care about liquids and food, sexual activity, care in relation to return to activities, to whom was undergone prostate surgery, and warning signs. We carried out the content and appearance validation of the material with 30 experts and all guidelines were validated with the final score greater than or equal to 0.8. Most experts assessed positively the appearance of the material, with an average of 89.7% of positive responses on 16 items assessed. Despite the use of numerical scales for the validation of the content and yes and not for answers in the appearance validation, it was shown that in such a study, the availability of spaces for the experts to give an opinion has proved of great value for improving the quality of the material. The experts contributed with suggestions for improved presentation of the material and illustrations, suggestions for terms commonly used by customers and questions about the adequacy of guidance and illustrations given. The guidelines have been reorganized and obtained 27 guidelines divided into 10 thematic categories, as well as introductory content. The results can provide the base for nursing practice and allow to perform new studies in clinical validation in order to obtain evidence about the impact of using this kind of material in achieving positive outcomes with clients, as well the possibility of subsidizing the development of protocols and / or specific plans of care and thus possibly facilitate nursing activities and consequently improve the recovery and quality of life of the clients.

Plant legumains, also termed vacuolar processing enzymes (VPEs), are cysteine peptidases that play key roles in seed maturation, germination, senescence, stress response, programmed cell death during development and defense against pathogens. Despite the increasing number of reports on VPEs, most of studies are on dicotyledonous legumain and their role in seeds. In this study, it was performed the characterization of sugarcane legumain, named CaneLEG. Kinetic characterization of the recombinant CaneLEG expressed in Pichia pastoris revealed that this enzyme has the main characteristics of VPEs, such as self-activation and activity under acidic pH. CaneLEG activity was strongly inhibited by the sugarcane cystatin named CaneCPI-3. In vivo interaction between legumain and cystatin was observed to barley proteins, indicating that legumains might be inhibited by cystatins in the plant. Furthermore, the CaneLEG and CaneCPI-3 gene expression was analyzed throughout sugarcane development and in plantlets treated with phytohormones. From these results, it was observed that these genes showed a tissue-specific expression pattern, with the strong accumulation of CaneLEG transcripts throughout the internode development. The up-regulation of CaneLEG and CaneCPI-3 genes in plantlets treated with ABA suggests that these proteins encoded by these genes may be involved in stress response and CaneCPI-3 may act on endogenous cysteine peptidase regulation. Our results suggest the CaneCPI-3 as the endogenous inhibitor of CaneLEG and the involvement of these proteins on the ABA-regulated stress response. Further, the gradual increase on CaneLEG expression in internode suggests the action of this enzyme on the development of this storage tissue. The results obtained in this work will serve as an initial tool to understand the roles played by CaneLEG and CaneCPI-3 on sugarcane.

Alongside with the establishment of the Brazilian Social Security, the Professional Rehabilitation of the National Institute of Social Security (INSS) has been created. It aims to provide its beneficiaries, partially or totally incapacitated for work, the indicated means to reenter the labor market and the context in which they live. This study intended to understand, identify and comprehend, from the perspective of occupational therapists, practices and conceptions that have been delineated by the profession in the area of Professional Rehabilitation at INSS, in the state of Sao Paulo. Based on a survey and an analysis of bibliographical and documental material on the theme in general and at the Institute in particular, the empirical research made use of a questionnaire applied with 40 of the 43 occupational therapists who act in the state. In-depth interviews were conducted with 6 of these participants. Also an interview with another occupational therapist, who works at INSS since 1980, was conducted in order to collect background data about the Professional Rehabilitation as well as the insertion of occupational therapy at the Institute. The resulting data of the questionnaires provided a general prospect of conceptions and practices of occupational therapists in the studied field and were related to those collected in the interviews. This allowed for the deepening of the themes, providing opportunities for further reflection and discussion about them. The main findings allow us to state: occupational therapists are amidst the construction of a new professional identity at INSS; most of them deemed to have taken specific actions of occupational therapy at the Institute and point out the job analysis and the evaluation of compatibility of the proposed new functions for the insured workers in this specificity. The therapist-patient relationship was indicated like fundamental to their practice. Overall, they identify series of factors that would implicate an evaluation more negative than positive about their performance at the Institute, caused principally by structural questions of the Program of Professional Rehabilitation, what is independent of them. However, they still keep the belief in the improvement of this structure, claiming for the need to increase the possibilities offered by even greater participation and accountability by companies, the construction of joint work with other sectors of society and government, as well as for the redesigning and expansion of the legislation that deals with professional rehabilitation in Brazil.
