Aspectos reprodutivos e sociais e resistência óssea em ratos machos submetidos ao exercício físico e/ou a um anabolizante esteróide

Nowadays the regular practice of sports is known as a way to obtain a better quality of life. On the other hand, the media has been distorting this idea, determining the ideal body as the hypertrophy phenotype. It is well known that the genetic factor does not allow all individuals to have this body shape. Besides the fact that, the anxiety of these people in obtain quick results, as one of the globalization’s consequence, make use of anabolic steroid to achieve this goal. However the bodybuilding or the strength muscle gain, make anabolic steroids users abuse and in major cases the users do not know the side effects. In front of these considerations, the present study evaluated the effects of the treatment with anabolic steroids and/or high intensity physical training on the corporal developing, the reproductive organs, bone parameters (strength and bone deformation) and seminal parameters as well the social behavior (aggressiveness). In other to obtain the experimental group, male Wistar rats were used, with 75 days old. The groups were divided into: Vehicle Non-Training (NV), Anabolic Steroid-Non-Training (NA), Vehicle-Training (TV) and Anabolic Steroid-Training (TA). These rats received i.m. injections, twice a week, of anabolic steroid (5mg/kg per animal of nandrolona decanoate) or vehicle (the same volume of peanut oil per animal) and the group TV and TA were submitted to physical training three times per week, during eight weeks. The body mass, wet weight of reproductive organs, femur and semen of the different groups were measured. The aggressive test was also realized in two steps: the first, within 4 weeks of the treatment and the other step in the end of the treatment, in this period the animal was isolated. It was not observed alterations in body mass of the groups. Though it was observed a benefic effect on the maximum strength of the... (Complete abstract click electronic access below)

As dificuldades de implantação de atividades experimentais investigativas no ensino de Química

Dissatisfaction with certain aspects of the educational processes of the traditional teaching has always existed, and new teaching methods have been routinely studied. The experimental investigative activity is one of those alternative practices. In this type of activity the experimentation is inserted with an investigative approach, in which the student must build the concept, with proposals that represent solutions to the excited problems. In the teaching of chemistry, specifically, the need and importance of experimentation is evident, beyond motivate students, aid in the understanding of chemical concepts relating them to reality. Realizing the contributions of this methodology for teaching and learning, through this research was conducted to understand the difficulties encountered by teachers for planning and implementation of these activities in the teaching of chemistry and therefore the reasons for the dominance of traditional teaching method. The subjects were undergraduate students of chemistry course that developed and implemented differentiated learning activities for teaching and teachers who accompanied the high school students who participated in the university extension project Inclusion Science and University students and teachers from public: Teaching and Learning Chemistry focuses on research and practice”. Through the data it was possible to identify some factors that affect and hinder the implementation of experimental activities in general, not only the investigative. However, despite the difficulties experienced by undergraduates, the majority considered the activity as an alternative teaching method interesting and innovative, able to produce interest, motivation and participation of students with subsequent learning. As well as the teachers, what with all the difficulties that they had declared facing when applying experimental activities, they admitted the pedagogical...

Proposta de sistemática operacional para implantação de sistemas de gestão ambiental em empreendimentos industriais

The implantation of environmental management systens (SGA) in companies is the first step to the company conquers the environmental certification and consequently the benefits of a sustainable production of products, services and activities can bring. However, in the way as they are proposals in bibliographies the implantation of the SGAs, does not identify the definition of the operational stages of implementation of the same ones, generating doubts on the real environmental and administrative performance that they can come to generate for the organization. In this direction, the present research brings a proposal of operational systematics for implantation of SGA in companies, detailing each stage of implantation, considering its particularitities. For in such a way, a revision of norm NBR ISO 14001:2004 was made, looking for to identify to the interpretation imperfections gifts in the normative system. Moreover, other methods of SGA implantation had been searched gifts in the bibliography, searching proposals that detailed the operational aspects of the implantation of the system. In the same way, the accomplishment of a period of training supervised in the first semester of 2007 made possible the practical experience of the functioning of a system of environmental management, beyond the contact with professionals of the area and the acquisition of documents that had helped in the development of the research. The result was the attainment of a detailed procedure more, defining the operational systematic of SGA implantation, beyond the generation of a flowchart, describing as to develop each stage. This detailing certainly will facilitate the implantation of a SGA in companies interested in improving its environmental performance.

Efeito do fornecimento de diferentes níveis de alumínio dietético na qualidade óssea de codornas poedeiras (Coturnix japonica)

O alumínio está presente de forma marcante em nosso cotidiano, com várias possibilidades de contaminação para o ser humano e animais, através da ingestão de alimentos ou aditivos presentes nos alimentos ou, também, através do uso de medicamentos. Por apresentar uma forte carga elétrica, um forte poder de polarização e características similares com elementos da hidroxiapatita, o alumínio age como um competidor de nutrientes na matriz óssea, Por isso, ele pode ser causa danos à saúde dos seres vivos, como a osteoporose. Diante disso, a presente pesquisa teve como objetivos estudar a influência de diferentes níveis de alumínio na dieta de codornas poedeiras, sobre as características físicas e químicas de seus ossos. A densidade e a porosidade óssea foram determinadas pelo método de imersão em água, utilizando o princípio de Arquimedes. Os resultados obtidos mostraram que concetrações até 20 mg de alumínio por kg de ração fornecida causa uma diminuição na densidade óssea e volta a aumentar para concetrações maiores que este limiar. A porosidade óssea, segue o inverso da densidade. Ela aumenta com concetrações até 20 mg de alumínio por kg de ração fornecida e volta a diminuir para concetrações menores

Avaliação do desempenho ambiental da produção canavieira com colheita mecanizada: contribuição à implantação de um sistema simplificado de gestão ambiental da propriedade

The consuming of the natural resources in the agricultural sector does not represent only one external factor of the productive process, but also it implies in a bigger cost for the production, justified for this environmental degradation. In view of the necessity of evaluating the sustainment of the agricultural businesses, the use of performance indicators if makes of extreme importance. The measurement of the support through environmentalindicators is one of the most accepted forms of performing the evaluation of one given agricultural activity. In this context, the Base System for Eco-certification of Agricultural Businesses (Eco-cert Rural) developed by the Embrapa Environment at Jaguariúna/SP, has for purpose to present a method of evaluation of the agricultural businesses, not only of the point of view of the ecological performance, as well as considering the social, economic and organizational aspects. Through the analysis of the performance of the activity and the regularization of the disconformities found, it makes possible the eco-certification of the activities in the varied existing protocols, offering technologies designed to the sustainable development of the agricultural businesses. Using Eco-cert.Rural, this work evaluated the contribution of the use of mechanized harvest in sugar cane handling, front to the traditional system of manual harvest, using the fire. In the Sugar Cane Activity General Performance Index, Agrícola Rio Claro scored 2,08 of a maximum of 15. Amongst all the indicators, those wich reached performance worse had been related to the Use of Energy and the Income, by increasing fossil fuel consumptiom, and implying income concentration due to resignations of rural workers. However, the improvements on the environment quality by supressing manual harvest through fire are very significant. Beyond the great reduction in...(Complete abstract click electronic access below)

Implantação iônica por imersão em plasma e deposição de filmes finos poliméricos provenientes da mistura hexametildisilazano/argônio

Thin polymeric films deposited by plasma are very atractive for many industrial and scientific applications, in areas such as electronics, mechanics, coatings, biomaterials, among others, due to its favorable properties such as good adhesion to the substrate, high crosslinking, nanomectric thickness, homogeneity, etc. In this work, thin films were deposited by plasma immersion ion implantation and deposition technique from a hexamethyldisilazane/argon mixture at different proportions. These films were subjected to several characterizations, such as, contact angle, which presented values near to 100 degrees, surface energy, with values near to 31 mJ/m2, hardness with values between 0.7 and 2.6 GPa, thickness from 100 to 200 nm, refractive index from 1.56 to 1.64, molecular structure presenting the following functional groups in the infrared spectra region: CHx from 2960 to 2900 cm-1; Si-H around 2130 cm-1; CH3 in Si-(CH3)x around 1410 cm-1; CH3 in Si-(CH3)x in 1260 cm-1; N-H around 1180 cm-1; CH2 in Si-CH2-Si bonds around 1025 cm-1; Si-O in Si-O-Si from 1020 to 1100 cm-1; Si-N in Si-H-Si bonds around 940 cm-1; CH3 in Si-(CH3)3 in 850 cm-1; Si-C bonds in Si-(CH3)2 around 800 cm-1; and Si-H in 680 cm-1 . From these characterizations, it was possible to conclude that the concentration of argon or hexamethyldisilazane in the mixture changed the resulting polymer

Identificação de áreas potenciais para implantação de aterro sanitário no distrito de floresta do sul em Presidente Prudente/SP

O crescimento das sociedades urbanas tem gerado um aumento significativo na produção dos resíduos sólidos urbanos, tornando o tema de disposição final amplamente discutido nas gestões públicas. Recentemente, a partir da criação da Lei Federal nº 12.305/2010, que institui a Política Nacional dos Resíduos Sólidos, foi estabelecido que a disposição final ambientalmente adequada dos rejeitos deve ser feita exclusivamente em aterros. O presente trabalho teve então como objetivo a avaliação de áreas potenciais para instalação de aterro sanitário no Distrito de Floresta do Sul no município de Presidente Prudente/SP. Para tanto, utilizou-se o SIG, como ferramenta do geoprocessamento, para análise espacial.

Marcadores de superfície de Células-tronco: estudo de reação cruzada inter-espécies

Mesenchymal stem cells (MSCs) are adult multipotent cells with fibroblastoid morphology and adherent to plastic. Furthermore, they can be obtained from different sources. Besides bone marrow, these cells are taken from umbilical cord blood, umbilical vein, saphenous vein, peripheral blood, arteries, liver and fetal pancreas, placenta, dental pulp and adipose tissue. MSCs derived from adipose tissue are important because of the abundant number of cells that can be obtained from this tissue, easy access and little discomfort to the patient. This study compared two techniques for obtaining MSCs from adipose tissue: mechanical dissociation (MD) and enzymatic digestion (ED). We also analyzed the inter-species cross-reactions using commercial monoclonal antibodies directed against surface antigens of stem cells from different species: mouse, horse, rabbit, monkey and human. We found that MD technique is favorable in relation to ED within 15 days of culture, and ED is more efficient in the first days of culture. The data also showed that MD causes less damage to cellular DNA. About inter-species cross-reactions, the monoclonal antibody A69 directed against stem cells from rabbits, which can be used in veterinary medicine, particularly in research involving horses

Diagnóstico dos resíduos de construção e demolição: uma contribuição à elaboração e implantação da gestão integrada dos RCD no município de Guaratinguetá – SP

The problem of solid waste has caused discussions about the huge amount that is generated in Brazilian cities, in particular the waste from construction and demolition (CDW), called spoil. In many cases these wastes are disposed of improperly and even criminally in urban areas, causing serious economic, social and environmental problems. Due to the lack of public policies and appropriate management of such waste came up with the CONAMA, in its resolution nº 307 of 2002, the obligation of municipalities in deploy the integrated management of construction and demolition wastes for the resolution of problems caused by inadequate management and disposal of such waste. By following a methodology suggested by Pinto & González (2005), with adaptations of other authors, it is proposed in this work the lifting of a diagnosis of the CDW in the municipality of Guaratinguetá-SP, through theoretical analysis and field research, with purpose to guide the public servants in the elaboration and implementation of integrated management. The results must contain information necessary for that end, such as the knowledge of generators, agents, collectors and transporters, disposition areas and the disposal of waste

Análise da densidade óssea de rádio-ulna de cães SRD utilizando o método de imersão

Imaging diagnosis is a medical specialty that uses imaging techniques to perform diagnosis. In diagnostic imaging various methods are used such as direct absorption of photons - SPA and DPA, radiographic photometry, the dual-energy radiographic absorptiometry - DEXA, ultrasound, magnetic resonance imaging, computed tomography and optical densitometry in radiographic image. The dog can be considered one of the most widely used animals in the study of bone diseases and searching for a reliable diagnosis, although not an ideal model for the study of osteoporosis, because these animals tend not to develop a decrease in bone mineral density. The objective of this study was to analyze bone density in mongrel dogs from the determination of the variation of density along the radio-ulna bone and also the mean value related to gender, weight and age of individuals. The density analysis carried out showed that for this data set, there is a significant difference in the case of gender and age of the animal and may generalize according to these variables. The only significant difference was found in the weight, which increases bone mass is related to weight gain through the growth of the animal
