Leptina: aspectos sobre o balanço energético, exercício físico e amenorréia do esforço

Abstract: The aim of this manuscript was to review the knowledge about leptin, detailing its relationship with energetic intake and physical activity. Leptin is an adipocyte hormone, recognized mainly for its putative role in control of energy expenditure, food intake, body weight and reproductive function. Leptin has still important peripheral actions, including its role on the ovarian tissue. The intracellular signaling mechanisms are recognized in hypothalamus, but in peripheral tissue are not fully understood. The exercise, when practiced by women, if not appropriately planned according to food intake, can modify the leptin release. When energy imbalances induced by exercise and/or deficient food ingestion occurs, low leptin levels are observed, leading to a reduction in GnRH (gonadotropin-release hormone), in LH (luteinizing hormone) and FSH (follicle-stimulating hormone) in pituitary, and consequently a minor release of ovarian estrogens. This process is named hypothalamic amenorrhea, and has repercussions in the woman's health. In this perspective, it is important to emphasize the need to evaluate the energy expenditure from exercise and to formulate adequate alimentary plans to these individuals.

Atitudes parentais em relação à educação inclusiva

Abstract: In order to describe parental attitudes toward school inclusion, 445 parents of elementary school students from first to fourth grade of two municipal schools of the city of Sao Paulo answered a questionnaire and the Likert scale General Inventory of Attitudes toward Inclusive Education (IGAEI) for assessing attitudes. The participants were 169 (37,98%) parents of students with special educational needs included in regular schools (G1) and 276 (62,02%) parents of students the school directors said did not have special needs (G2). The instruments were collectively applied during a parent teacher meeting using individual answer sheets. The results showed that both groups of parents tended to have positive attitudes in relation to inclusive education. However, parents of special educational needs students' attitudes were more positive. Results referring to other researched variables, i.e. types of special educational needs in inclusion process, are also presented. This study tends to corroborate research results from other countries, though some discrepancies have been perceived. In conclusion, this study highlights the importance of parental involvement in the development of inclusive educational systems and suggests that more research is required in the Brazilian educational context.

Disfunção autonômica cardiovascular no diabetes mellitus experimental

Abstract: Much new information has been published in the last few years regarding pathophysiology of cardiovascular autonomic dysfunction in diabetic rats and mice. Our group has been studying the time-course cardiovascular changes associated with experimental diabetes in the last years, and obtained consistent evidences of severe dysautonomia in diabetes animal models. The aim of this manuscript is to review the contribution that studies involving different animal models of insulin deficiency or resistance have given to understand, treat and prevent diabetic cardiovascular autonomic dysfunction.

Atrial natriuretic peptide (ANP)-granules in the guinea pig atrial and auricular cardiocytes: an immunocytochemical and ultrastructural morphometric comparative study

Abstract: The atrial natriuretic peptide (ANP) is a peptide hormone that is mainly produced in the cardiac atria, where it is stored within granules. It is known that the four regions of the atrial-auricular complex (two atria and two auricles) produce and store ANP in the granules. However, no report has been presented comparing the presence of ANP, and the number and diameter of atrial granules in the atria and auricles. ANP immunoreactivity was detected in cardiocytes from the four regions of the atrial-auricular complex. No differences were observed among the regions. The number of granules was greatest in the right atrium followed by the left atrium and left auricle and right auricle, in this order. The diameter of granules in the cardiocytes was significantly largest in the right atrium and reduced via the left auricle to the left atrium and right auricle. Both the number and diameter of the granules are larger in the right atrium in comparison with the other regions of the atrial-auricular complex, which leads to the supposition that this region is the one that most synthesizes and stores the ANP.

Migração de ε-caprolactama de embalagens contendo poliamida 6 para simulante ácido acético 3% e validação do método analítico

Abstract: The aim of this work was to develop and validate an analytical method to determine e-caprolactam in 3% acetic acid solution and to study its migration from polyamide 6 into food simulant. Gas chromatography was used with e-caprolactam as an analytical standard and 2-azacyclononanone as an internal standard. The linearity was obtained by the concentration range of 1.60 to 640.00 µg.mL-1, with a correlation coefficient of 0.9999. Detection and quantification limits of the method were 0.24 ng and 1.60 ng, respectively. Relative standard deviations obtained for method precision were less than 4.3%, while method accuracy showed recovery between 100 and 106%. The method was able to quantify e-caprolactam in the simulant, showing a wide linearity, good precision and accuracy. For the migration assay, polyamide 6 films were placed in glass vials containing 10 mL of simulant, which were hermetically capped and exposed at 40 °C for 10 days (total immersion). The amount of e-caprolactam that migrated from packaging into the simulant varied from 7.8 to 10.5 and 6.9 to 7.6 mg.Kg -1, for films used as meat products and cheese packaging, respectively.

Efeitos cardiovasculares da abstinência do fumo no repouso e durante o exercício submáximo em mulheres jovens fumantes

Abstract: OBJECTIVE: The objective of the present study was to verify the effect of tobacco smoking abstinence on cardiovascular responses to progressive submaximal physical exercise in sedentary female smokers. METHODS: Systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were non-invasively measured in young non-smoking women (NSW, n = 7) and smoking women (SW, n = 7), with and without tobacco abstinence for 24 hours, at rest, during the accomplishment of a submaximal bicycle ergometric test and recovery period. RESULTS: At rest, DBP and HR were higher in the SW group (76 ± 1 mmHg and 86 ± 5 bpm) when compared to the NSW group (68 ± 2 mmHg and 72 ± 2 bpm). After 24 hours of no tobacco use, the groups presented similar values. During exercise, SBP and HR increased in the studied groups. DBP was higher in the SW group (~15%) in relation to the NSW group in all periods of exercise training. In the abstinence period, DBP only increased in the last load of exercise. During recovery period, in basal condition and 24h-abstinence, both DBP and HR were higher in the SW group when compared to the NSW group. CONCLUSION: These results show that young female smokers present harmful consequences in hemodynamic parameters at rest and in response to submaximal exercise. These findings can be partly reverted by short-term abstinence from tobacco use.

Thermal treatments to minimize fading effects of colored glass radiation detectors

Abstract: The use of colored glasses (bronze, brown and green) for high-dose dosimetry in routine procedures and as gamma radiation detectors has been investigated in this study. Different dosimetric techniques were employed using a densitometer, a spectrophotometer, a thermoluminescent reader and an electron paramagnetic resonance system. However, these kinds of samples show a strong post-irradiation thermal decay at room temperature, which is a problem for high-dose dosimetry purposes. This effect may be avoided by always taking measurements of the glass samples after the same post-irradiation time, for example 1 h. In this work, different thermal treatments have been applied to the glass radiation detectors. The influence of post-irradiation thermal treatments on the glass response fading was studied using different kinds of glass samples (bronze, brown and green). This process destroys the unstable color centers of the glass samples that are responsible for the initial strong response decay; after that the response becomes stable at room temperature. The different kinds of glasses show the possibility of their use for high doses of industrial, medical and agricultural applications, with the advantages of very low cost and easy handling.

Educação Física Escolar no ciclo II do ensino fundamental: aspectos valorizados pelos alunos

Abstract: For the majority of Brazilian adults, remind the School Physical Education, let them remember the traditional sports worked as important content in the classes. As a school teacher, we fell some needs to investigate if this social representation of the adults remains on the students mind. So, this paper aims at investigating what are appreciated contents in the school physical education. The samples were eighty seven, which are students from sixth to ninth grade of elementary school, in the first semester, at private school, located in the east of the Sao Paulo City. This is a qualitative study, descriptive type. The students answered for the question: What do you think is important in the physical education classes? Why? The answers were registered, written out, analyzed and interpreted. The results showed us that the most important apprenticeship content for the students in this semester was sport, confirming the permanence of sport in the physical education image, interpreted as a strong social representation component. Well-being and physical development had been mentioned few times than sports. From these results, it is possible to reflect on the reasons that the others physical education contents no yet attained the students as the same importance that sports.

Avaliação das propriedades de fluxo dos granulados e dissolução de comprimidos de hidroclorotiazida 50 mg obtidos por granulação úmida

Abstract: The wet granulation process still finds large applicability close to the modern pharmaceutical industry for the production of tablets, because it eliminates some of the main attributed problems of the direct compression: the segregation tendency and the low flow properties of the powders during the process. The present work evaluates and it compares through micromeritical studies and statistical analysis the flow characteristics of granulates destined to the development of tablets of hydrochlorothiazide 50 mg. Three binders were tested (paste of starch and the aqueous dispersions, prepared to cold, of pregelatinized starch and povidone). It was still evaluated the compatibility between the drug and the employed excipients, through termoanalytical studies (DSC), and the influence of the extra granular addition of the "superdisintegrant" crospovidone in the values of dissolution efficiency (%DE) of the obtained tablets. The obtained granulates presented good flow and compressibility properties, characterized by: values of compressibility index between 5 and 15; Hausner ratio less than 1,25 and angle of repose between 30 and 35o. The crospovidone addition did not increase the values of %ED of the developed formulations, in the experimental conditions employed, although it has reduced, in way a low significance, the disintegration times of the formulations.

Efeitos da suplementação do 17beta-estradiol no dano oxidativo cardíaco de ratas submetidas à privação dos hormônios ovarianos

Abstract: OBJETIVO: avaliar o estresse oxidativo em tecido cardiaco de ratas ooforectomizadas, com ou sem terapia hormonal. METODOS: ratas Wistar foram divididas em tres grupos: grupo controle (GC), grupo ooforectomizada (GO) e grupo ooforectomizada + suplementacao hormonal (GOS). A privacao estrogenica foi obtida pela ooforectomia bilateral. Uma semana apos a ooforectomia, um pellet de 1,5 mg de 17b-estradiol foi implantado nos animais do grupo GOS. Nove semanas apos a ooforectomia, o tecido cardiaco foi obtido para a analise do estresse oxidativo por meio da medida da quimiluminescencia e da atividade das enzimas antioxidantes catalase (CAT), superoxido dismutase (SOD) e glutationa peroxidase (GPx). RESULTADOS: a quimiluminescencia estava aumentada no GO (7348±312 cps/mg proteina) quando comparado ao GC (6250±41 cps/mg proteina, p<0,01), mas nao houve diferenca significante entre GC e GOS (6170±237 cps/mg proteina). A ooforectomia reduziu a atividade da SOD (22%, p<0,001) e da CAT (35%, p<0,05) no GO comparado ao GC. A terapia hormonal normalizou a atividade das enzimas antioxidantes no GOS. Nao houve significância estatistica na atividade da GPx quando os grupos estudados foram comparados. CONCLUSOES: a privacao dos hormonios ovarianos induziu aumento do estresse oxidativo e reducao das defesas antioxidantes no tecido cardiaco. No entanto, a terapia hormonal preveniu o estresse oxidativo apos a ooforectomia, provavelmente devido a um aumento das enzimas CAT e SOD no musculo cardiaco. Esses achados sugerem uma importante participacao do estresse oxidativo nas disfuncoes cardiovasculares observadas em mulheres apos a menopausa, reforcando a importância da terapia hormonal para o manejo dos riscos de doencas cardiovasculares neste grupo de mulheres.

Aplicação da nbc t 15 por empresas dos segmentos de bebidas e alimentos: uma pesquisa documental

Abstract: With adequate disclosure of information, interested parties will have instruments for evaluating the social performance of the organization. Besides generating information on finances and economics, accounting, in fulfillment of its role as supplier of information for various types of users, must also furnish information on social responsibility. The objective of this research was to verify whether the largest companies in terms of revenues in each segment of the Economy evidence information on social responsibility in an adequate way. As methodology, bibliographical research was made and documentary research developed starting with a checklist based in NBC - T 15, aimed at verifying the level of disclosure of information on social responsibility. Fourteen large revenue companies in each segment of the Economy had been selected; with the final sample including the 14 companies that had published their accounting statements. It can be stated that five companies showed poor notion of the concept; four presented excellent performance in the disclosure of information o social responsibility, while the others presented good or regular performance. It was verified that despite the scarcity of norms on social responsibility and even though they may not evidence their preoccupations clearly, companies are concerned about social questions. Keywords: Disclosure. Information. Social responsibility.

Efficient representations of row-sorted 1-variant matrices for parallel string applications

Abstract: We investigate the efficient storage of row-sorted 1-variant (m + 1) × (n + 1) matrices, m > n, that have the following properties: the rows are sorted in strictly increasing order and the set of elements of each row differs only by one single element from the set of elements of the next row. It has been shown that row-sorted 1-variant matrices are important in several parallel string comparison applications. Due to the large amount of redundancy in the row elements, we investigate efficient data structures to store such matrices. In this paper we propose a representation that stores a row-sorted 1-variant matrix in O(m log m) space and access time of O(log m) and can be constructed in O(m log m) time. We thus seek a representation that constitutes a nice balance between access time, representation construction time, and space requirement.

Autonomia e educação física: uma perspectiva à luz do ideário da promoção da saúde - autonomy and physical education: a perspective in the light of the ideas of the health promotion

Abstract: Resumo O termo autonomia tem sido frequentemente utilizado na Educacao Fisica de maneira funcional, restringindo seu conceito a operacionalizacao das acoes motoras ou cognitivas que um individuo e capaz de realizar de maneira independente. Assim, a autonomia e considerada como sinonimo de independencia fisica e cognitiva e reduzida ao sentido de funcionalidade independente. Desta forma, o proposito do presente trabalho e iniciar discussoes e reflexoes que incitem a busca de referencial teorico que traga suporte a criacao de relacoes entre Educacao Fisica e o ideario da Promocao da Saude considerando a autonomia como questao central destas duas areas. As conclusoes dos autores apontam que a autonomia expressa no Ideario da Promocao da Saude, compreendida especialmente a luz do pensamento filosofico, tera implicacoes na pratica em Educacao Fisica, na busca de meios que nos conduzam ao estimulo da autonomia das pessoas. Palavras-Chave: Autonomia, Educacao Fisica; Promocao da saude.

Electroless nickel deposition onto silicon surfaces for micro and nanoelectronics applications and microtechnology processes

Abstract: We studied and characterized the processes of electroless nickel deposition in order to use it in microelectronics and microtechnology. We perform electroless nickel deposition on silicon surfaces with acid solution on palladium preactivated surfaces as well as alkaline solution without palladium preactivation. Electroless deposition was also performed on aluminum surfaces, deposited by evaporation onto silicon oxide. MOS capacitors were also fabricated to perform electrical characterizations of the structure (nickel-aluminium-oxide-silicon) using capacitance-voltage plots (C-V curves). In addition, we also presented the use of electroless nickel deposition for chemical sensors which were fabricated using conventional microelectronics techniques. (© 2007 WILEY-VCH Verlag GmbH & Co.

Recent results for the brazilian two-pion exchange nucleon-nucleon potential

Abstract: We have recently performed a relativistic O(q4) chiral expansion of the two-pion exchange NN potential, and explored its configuration space content by fitting the theoretical expressions to parametrized simply formulas. In order to test the applicability of our parametrized potential, we studied the pion plus production in proton-neutron scattering at threshold an compare our results to the ones given by Reid 93 and v18 potentials. We shown that our results are very close to the v18 potential, which means that the potential is reliable and trustful.

Brazilian Relativistic O(q 4 ) Two-Pion Exchange Nucleon-Nucleon Potential: Parametrized Version

Abstract: In our recent works we derived a chiral O(q4) two-pion exchange nucleon-nucleon potential (TPEP) formulated in a relativistic baryon (RB) framework, expressed in terms of the so called low energy constants (LECs) and functions representing covariant loop integrations. In order to facilitate the use of the potential in nuclear applications, we present a parametrized version of our configuration space TPEP.

Percepção sobre a carreira dos profissionais de educação física do programa clube escola

Abstract: There are few studies on training and careers for professionals who work in the non-school field. Aiming to identify and discuss whether the perception of one's own career has some relation to the identification of needs for continuing education, we focus attention on Physical Education professionals of the Municipal Office on Sports Leisure and Recreation of Sao Paulo because they are tied to a program that has been implemented since 2007 - the Club School Program. The research methodology is qualitative, with phenomenological orientation, having ninety-four, among the one hundred seventy-three professionals working in the Clube Escola, responded to a questionnaire with two open questions. It was identified that 70% of the professionals interviewed are satisfied with their current time in their career, 72% think the continuing education is important and, in general, the professionals that are satisfied with their career, are willing to remain in constant retraining when encouraged to do so. It was concluded that the positive perception about professional career appears to be related directly to the professionals’ inclination to keep participating in actions aimed at their continuing education. Moreover, this research has taken the first steps in professional careers in Physical Education and it is recommended to invest in more studies outside the subject of Scholar Physical Education.
