Efeito protetor após sessões de exercício excêntrico: comparação entre membros superiores e inferiores

The objective of the present study was to compare in which part (lower limb or upper limb) the repeated bout effect has the greatest magnitude. Twelve males individuals with no recent (6 months) experience with resisted training participated in this study. The subjects were randomly divided into two groups (legs and arms) and came to the laboratory 5 times. 1st) adaptation to the dynamometer. 2nd) to perform one bout of eccentric exercise (EE) and provide markers such as isometric peak torque (IPT), delayed onset muscle soreness (DOMS) (both collected before and after the bout) and concentration of the creatine kinase (CK) enzyme in the blood (only before the bout). 3rd) 48 after the first bout the same markers were collected again. After 14 days, the methodologies used in the 2nd and 3rd visits to the laboratory were repeated respectively to determine the repeated bout effect. A significant decrease of IPT and a significant increase of CK and DOMS were found immediately after and 48 hours after the first bout of EE for the arms group. The legs group showed a significant increase in CK (48 hours after the EE) and DOMS (immediately after the EE) resulting from the first bout. In the arms group, the second bout did not cause significant increase in CK or DOMS on any of the situations, however, it provoked a decrease in force production immediately after the EE. The legs group showed a significant increase of DOMS immediately after the second bout of EE, which caused no significant increase in CK. The only marker in which the repeated bout effect happened for both groups was CK. No significant difference was found between the protections for both groups. Taking into account the results, it’s been discussed whether there is a relation between the susceptibility to muscle damage and the repeated bout effect, and also...(Complete abstract click electronic access below)

Comparação da sensibilidade da técnica parasitológica (OPG) e da PCR para o diagnóstico de Strongyloides venezuelensis em fezes de ratos (Rattus norvegicus) da linhagem Lewis infectados experimentalmente

Espécies do gênero Strongyloides são importantes parasitas de humanos e animais domésticos e aquelas que parasitam roedores são freqüentemente utilizadas como modelos experimentais para o estudo da estrongiloidíase. S. venezuelensis parasita ratos (Rattus norvegicus) e seu estudo tem permitido o entendimento de mecanismos imunológicos envolvidos na relação parasita–hospedeiro da estrongiloidíase humana e animal. O diagnóstico parasitológico de S. venezuelensis pode ser realizado pela detecção de ovos embrionados nas fezes, com o uso do OPG (ovos por grama de fezes), também empregado no monitoramento da infecção. Entretanto, essa técnica se mostra pouco sensível quando a carga parasitária é leve. Os métodos moleculares aumentam a sensibilidade e a especificidade das análises. A PCR tem se mostrado como uma técnica sensível e precisa na detecção de parasitas em tecidos e fezes de hospedeiros infectados. A fim de comparar a sensibilidade das técnicas de OPG e PCR em ratos Lewis infectados por S. venezuelensis, foram realizados dois protocolos no presente estudo. No Protocolo I foi comparada a sensibilidade das duas técnicas em amostras de ratos Lewis com diferentes cargas parasitárias. A PCR com o emprego par de primers descrito por Dorris et al. (2002) obteve melhores resultados que o OPG nos grupos inoculados com 40 L3, considerada como infecção leve. Entretanto, não foi verificada diferença estatística significativa entre as técnicas (P>0,05), provavelmente por terem sido utilizados poucos animais (n=10). O outro par de primers utilizado foi desenhado a partir de uma seqüência parcial do gene do rDNA de S. venezuelensis e não foi capaz de detectar a presença do DNA do helminto em nenhuma amostra desse grupo. Já nos grupos inoculados com 400 e 4000 L3, tanto a PCR com...(Resumo completo, clicar acesso eletrônico abaixo)

Comparação da força de preensão palmar e composição corporal entre mulheres mastectomizadas ou não

Introduction: Loss of muscle strength may represent a burden on everyday tasks significantly compromising the quality of life for mastectomy patients. In addition to the reduced strength of the upper limb, has been shown in mastectomy patients and difficulties in reducing grip. Objectives: To analyze the possible differences in grip strength among women undergoing breast cancer surgery and to compare the body composition. Methods: In the control group (CG n = 46) women participated in the community of FCT / UNESP aged 35 to 70 years without acute orthopedic pathologies. In the experimental group (EG n = 49) participated in women undergoing surgery for breast cancer, without bilateral lymphedema and independent of time and type of surgery. Were evaluated by dynamometer, by Dual Energy X-ray absorptiometry (DEXA) and physical assessment. Results: We observed significant differences in grip strength (p = 0.000), when the group after mastectomy compared with the control group and the radical mastectomy surgery left and quandrandectomia left (p = 0.004). Regarding the presence of lymphedema, statistical difference was observed in the composition of lean mass and trunk fat (p = 0.05). Conclusion: The results of this study suggest that the experimental group are lower grip strength and trunk lean body mass when compared with the control group. The experimental group showed higher values of fat mass when there was presence of lymphedema

Analise de defeitos em motores através de vibração mecânica: estudo de caso

Revolving machines are among the most used equipment in general industry and therefore expenditures on this equipment class are a significant portion of the total amount spent by the company. If there is an unscheduled stop of some of this equipment, industrial plants can lose huge amounts of money caused by interrupted production and parts delay. Others may increase significantly maintenance costs due to consequences elsewhere not affected before. Even plant and people safety can be in danger if there is an operation interruption without a backup system start. This work is focused on a rotating system case study which is monitored by vibration analysis that shows that is possible to determine when is the most appropriate time for equipment intervention without any reliability loss just by using a simple and cheap system which is not much used because professionals are not aware to its utility. Industrial facilities were evaluated by fail detection and historical analysis in some equipment in order to show feasibility of vibration analysis through a before-during-after process. The plant evaluated is part of a chemical multinational located in Guaratinguetá-SP. At this time, that plant had around 650 critical equipment monthly monitored and no unscheduled shutdown was registered in one year period due to equipment monitoring

Análise da flexibilidade e da postura em jovens atletas praticantes de futebol

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...

Comparação de custo e viabilidade técnica de obras com parede de concreto em relação a obras de alvenaria estrutural

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

Avaliação e comparação do perfil de dissolução do Fluconazol 150mg cápsulas produto referência, genérico e similar

Fármacos com alta permeabilidade intestinal, ampla faixa terapêutica e ausência de evidências documentadas de bioinequivalência ou problemas de biodisponibilidade devido à formulação, foram considerados bioisentos pela ANVISA (RDC 37/2011), ou seja, os fármacos que se encaixam nesta categoria não necessitam de estudos de biodisponibilidade relativa/bioequivalência para serem comercializados. Dentre os catorze produtos que receberam a bioisenção da ANVISA, encontra-se o fluconazol, antifúngico aprovado atualmente para ser comercializado em vários países, inclusive no Brasil, onde inúmeras opções comerciais do produto fluconazol cápsulas, genérico ou similar, podem ser adquiridas. Tendo em vista a bioisenção do produto fluconazol cápsulas e sua larga utilização no mercado brasileiro, o estudo do perfil de dissolução deste produto torna-se relevante. Sendo assim, este trabalho avaliou 2 produtos genéricos e 2 produtos similares frente ao medicamento referência em relação aos seus perfis de dissolução e a similaridade entre eles. Os resultados foram avaliados seguindo a RDC 31/2011 da ANVISA que prevê o cálculo do fator de similaridade entre os perfis de dissolução. E, pôde-se observar que apenas 1 medicamento genérico apresentou o fator de similaridade adequado (entre 50 e 100), sendo 51,60, os demais medicamentos testes apresentaram valores fora do intervalo adotado pela ANVISA. Através desses resultados, conclui-se que intercambialidade do medicamento referência pelo medicamento genérico ou similar não é adequada, uma vez que eles não são considerados iguais, salvo um dos medicamentos genéricos.

Analise mecânica e microestrutural em estruturas tubulares aeronáuticas soldadas de aço ABNT 4130

Airplane Motor Cradles have a complex geometry, since they require different conbinations between different tubes and TIG welded in several angles. In T-25 aircraft and Universal T-27 Tucano (EMBRAER / FAB), besides having to bear the engine balance, these components maintain fixed the nose landing gear in another extremity. They are considered critical to flight safety, and for this reason, the aviation standards are extremely rigid in their production, imposing a zero index” of defects on the final weld metal quality. These structures may be containing an historical of welding repairs, whose effects on their structural integrity are not computed. In this work we analyzed the standardised AISI 4130 steel and the raw steel of tubes to the Airplane Motor Cradles. First of all, microscopy and microanalysis of the base steel, then we analyzed the effects of the TIG weld. Tensile testing was conducted to measure the difference between the mechanical properties of standardised steel and without this treatment

Análise comparativa do perfil histoquímico entre músculos de tropidurus psammonastes e comparação com outras do mesmo gênero

O desempenho locomotor de um indivíduo pode ser considerado produto de interações multivariadas em torno de sua morfo-fisiologia, sendo particularmente determinado pela maneira como seus músculos se contraem. Essa maneira como a contração ocorre é influenciada tanto por parâmetros energéticos (atividade enzimática e proporção de fibras de contração rápida); quanto estruturais (comprimento de fibras e tendões). Para quantificar a proporção de fibras musculares, foram obtidos cortes histológicos em criostato, de seis grupamentos musculares congelados de oito individuos de Tropidurus psammonastes e um grupamento muscular, o iliofibularis, de quatro individuos de Tropidurus semitaeniatus. Os cortes foram corados por meio de técnicas histoquímicas e as fibras contadas. O perfil metabólico foi contrastado entre os músculos de um mesmo indivíduo e essa comparação serviu de base também para interpretação em relação à informações semelhantes obtidas em estudos com ileofibularis em outras sete espécies de lagartos da família Tropiduridae. O resultado mostrou algumas variações entre os músculos de um mesmo indivíduo e entre os mesmos músculos em indivíduos diferentes

Comparação de eficiências do uso de sistemas construídos de áreas alagadas (Constructed Wetland Systems - CWS), tipos ascendente e descendente, para tratamento de efluentes

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

Comparação das técnicas semi-quantitativa e quantitativa nas infecções relacionadas a cateter em neonatos e determinação da resistência à oxacilina nos Staphylococcus spp

Study the semi-quantitative and quantitative technique in the diagnosis of catheter-related infections in newborns and to determine oxacillin resistance in Staphylococcus isolated. It was analyzed 353 catheter tips from 273 newborns in the Neonatal Unit of Hospital FMB. To confirm the diagnosis of infection, were analyzed the clinical data of newborns, the presence of at least one positive blood culture and growth of ≥ 1000 CFU/mL on quantitative culture and/or ³15 UFC on semiquantitative culture, with the same microorganism isolation (species and drug sensitivity) in blood culture and no other focus of infection except the catheter. The disk diffusion technique was used to check similarity of strains and resistance to oxacillin. Of the 353 tips analyzed, 39 were included in this study as the inclusion criteria. The semiquantitative culture was positive in 26 (66.7%) catheters and quantitative culture was positive in 24 (61.5%). Of 273 patients, 19 (6.9%) had a diagnosis of catheter-related bloodstream Infection (CR-BSI). Of the 19 episodes of CR-BSI, S. epidermidis was the predominant etiological agent (84.2%). The resistance to the antibiotic methicillin was found in 14 (73.7%) strains of Staphylococcus. The semiquantitative method was more sensitive (79%) compared with the quantitative method (63%). The use of antibiotics may have influenced the sensitivity of the quantitative method as the microorganisms present in the lumen are exposed to higher concentrations of antibiotics administered via the catheter

Amplificação, clonagem e sequenciamento do promotor de um gene que codifica uma aquaporina com expressão específica em rais de eucalipto (Eucalyptus grandis)

A biotecnologia define-se pelo uso de conhecimentos sobre os processos biológicos e sobre as propriedades dos seres vivos, com o fim de resolver problemas e criar produtos de utilidade. É importante frisar que uma das principais vantagens da biotecnologia moderna voltada para a área vegetal é a de poder gerar estratégias de melhoramento aplicáveis a diferentes culturas. Uma das principais estratégias de ação nessa área trata da produção de plantas geneticamente modificadas com transgenes de interesse. Nesse contexto, a identificação e caracterização de promotores com padrão de expressão tecido-específico é essencial para que a expressão de tais transgenes em plantas de interesse agronômico e florestal, como em eucalipto, fique limitada a determinados órgãos/tecidos. Assim, o presente trabalho teve por objetivo clonar e sequenciar a região promotora de um gene com expressão específica em raiz de eucalipto cujo produto gênico tem similaridade a uma aquaporina. Uma vez clonado, o promotor foi introduzido em vetor binário e inserido em plantas de tabaco visando a sua caracterização funcional. Além disso, a expressão do gene em estudo foi investigada em eucalipto, e uma analise filogenética comparativa com outras angiospermas foi empreendida
