Características da carcaça e alometria dos tecidos de cabritos F1 Boer × Saanen

Com o objetivo de avaliar as características de carcaça e a alometria dos cortes comerciais e dos tecidos de cabritos F1 Boer × Saanen, 35 animais foram abatidos ao atingirem 5, 10, 15, 20 e 25 kg de peso vivo (PV). A dieta dos animais foi composta de leite de vaca nos primeiros 49 dias e ração à vontade do sétimo dia até o abate. Os cortes foram obtidos após o resfriamento da carcaça e a perna foi dissecada em músculo, osso e gordura. O PV teve efeito linear decrescente no rendimento de carcaça fria e na área de olho-de-lombo por kg de carcaça. Os pesos de perna, paleta e pescoço em relação à carcaça fria decresceram linearmente, mas houve efeito quadrático sobre o rendimento de costelas e lombo. O crescimento de paleta, pescoço e perna foi isométrico (b=1) ao do corpo, enquanto o das costelas e do lombo foi mais lento (b¹ 1). Os músculos da perna cresceram igualmente, a gordura mais lenta e os ossos mais rapidamente que a perna, enquanto o desenvolvimento da gordura subcutânea foi mais tardio que o da intermuscular. Para obtenção de carcaça de 8 a 11 kg com rendimento superior a 44%, boa proporção de músculo e gordura com menor perda durante o resfriamento, recomenda-se abater os animais com PV entre 20 e 25 kg, mas, se o objetivo for carcaça de menor peso, o abate dos animais deve ser feito ao final do aleitamento com aproximadamente 10 kg de peso corporal.

Reação do tecido conjuntivo subcutâneo de ratos ao implante de Artglass®: estudo histológico

Indirect composite resin systems have been routinely recommended for making restorations in distressed patients. The purpose of this study was to evaluate histologically in rats the effect of chronic stress on the reaction of subcutaneous connective tissue after implant of Artglass™. For this purpose, 60 rats were divided into four groups (GI (control), GII (stressed), GIII (Artglass™) and GIV (Artglass™. / stressed) received dorsal subcutaneous implants of polyethylene tubes containing saline solution (GI and GII) or Artglass™ (GIII and GIV). In groups of four animals were sacrificed at 7,14 and 28 days postoperatively. The results allowed to observe more intense inflammatory reaction and tissue organization later in the animals subjected to stress.

Laminados cerâmicos em dentes tratados endodonticamente: considerações restauradoras e endodônticas com finalidade protética

A harmonia e beleza de um sorriso podem ser comprometidos pela presença de apenas um dente da região anterior que se apresente escurecido, mesmo que os demais elementos estejam alinhados e com forma adequada. A alteração de coloração, mesmo que mínima, sendo na região frontal é capaz de gerar um ponto de tensão e de desequilíbrio no sorriso, concentrando o olhar do observador no local1,2,3. Logo, a demanda dos pacientes por um sorriso estético, belo e harmonioso aumenta o desafio do profissional que visa integrar as características ópticas de um dente anterior despolpado e escurecido com os demais dentes polpados e sem manchamentos significativos. O clareamento é a alternativa mais conservadora para resolver o escurecimento em dentes despolpados. Apesar de resultados satisfatórios, alguns clínicos e autores relutam em assumir, como rotina, os procedimentos de clareamento para dentes despolpados, pelo alto índice de recidiva de escurecimento4,5. Mas, é importante lembrar que as recidivas descritas, normalmente, não contemplam um retorno aos valores inicias de manchamento. Deve ser feito um bom planejamento, levando em considerações fatores como a idade do paciente, o grau de escurecimento, o tempo em que o dente se encontra escurecido e a dificuldade em se alcançar o clareamento do dente, que são determinantes para o sucesso do tratamento clareador e para estabelecer a longevidade do clareamento obtido. Por isso, não são todos os dentes despolpados que apresentam alteração de cor que podem ser clareados, devendo ser avaliados com precisão os critérios estabelecidos3. Os dentes tratados endodonticamente e escurecidos, muitas vezes, necessitam da reintegração estética, associando as técnicas de clareamento com procedimentos restauradores ou, dependendo da condição do dente, a escolha imediata por procedimentos restauradores diretos ou indiretos.

Temporomandibular disorders in females: acupuncture compared to occlusal splint

To compare the effect of acupuncture and occlusal splint in the treatment of temporomandibular disorders (TMD) in female patients.Method: Forty-eight female patients (mean age of 39.3±6.8 years) with diagnosed pain in muscles or joint according to RDC/TMD criteria were attended at UNESP - Aracatuba Dental School. Including criteria were reported pain in the chewing muscles and/or in the temporomandibular joint measured by a visual analogue scale (range from 0 to 10) and a reported reduction of the maximum mouth opening. Excluding factors were major occlusal problems, systemic diseases, pregnancy and age below 18 years. After randomization, the first group was treated with acupuncture performed by instructed dentist. The second group was treated with occlusal splint. The outcome variables were assessed at baseline (prior to the first treatment session) and after 1, 3 and 6 months. Primary criteria of success were improvement of mouth opening and pain reduction.Result: Acupuncture group exhibited chewing pain decrease from 5 (at baseline) to 1, 2 and 1 after 1, 3 and 6 months, respectively. In the splint group, chewing pain decreased from 4 to 2, 1 and 2 after 1, 3 and 6 months, respectively. The mouth opening (in mm) increased from 28 (at baseline) to 42, 44 and 46 after 1, 3 and 6 months, respectively in the acupuncture group. In the splint group, mouth opening improved from 29 to 40 after 1 month, and to 43 and 42 after 3 and 6 months. A significant pain reduction was noted for both groups when compared to the baseline (p<.001; Wilcoxon test). Acupuncture group had a significant clinical improvement of opening mouth (Mann-Whitney). Conclusion: The present outcomes suggest a positive association among acupuncture and occlusal splint on the reduction of chewing pain. Acupuncture was more effective in the mouth opening increase.

Diagnóstico dos elementos de drenagem da área urbana de Rio Claro - SP: subsídeos para o plano diretor

The management of urban areas must consider aspects related to urban drainage, especially in hot and humid environments, and such aspects must be incorporated on director plans. This is quite important in urban areas settled on natural fragile hydro-geomorphologic areas. So, the main aim of this paper was to present the urban drainage diagnostic made in Rio Claro (SP-Brazil), discussing its results and evaluating the applied techniques. Further, there were presented some proposed directions based on such analyses. From the obtained results it was possible to verify that the impacts caused by the inefficient urban drainage system incur on direct and indirect effects such as flood, erosion and water quality degradation.

Início de ativação muscular de estabilizadores primários e a capacidade física para avaliar estabilização lombo-pélvica

Introduction: Due to the high incidence of low back pain without apparent cause, different approaches to evaluate the lumbar instability has been proposed, such as surface electromyography to determine pre-activation and the ability of lumbar stabilization through functional physical assessment. In this context, the objective of this study was to evaluate the early activation of the primary stabilizing muscles in subjects without low back pain, with different physical abilities function (CFF). Method: Study participants were 20 subjects with 19.8 ± 1.4 years, 55.7 ± 8.8 kilos, 1.66 ± 0.08 m, of both sexes. The subjects underwent six Tests Physical Function (TFF) and the Test of Fast Moving Flexion Arm (TMRFB) to capture the electromyographic activity of the lumbar multifidus muscles (LM) and internal oblique - lower fibers (HI). Were assigned weights for each functional test and the result of the physical capacity of the final functional subject ranged from 0 to 100%. In the analysis of TMRB was considered the onset time of activation between the ML and HI. Results: Regarding TFF 2 (10%) subjects were considered to have normal physical capacity, 6 (30%) with good physical ability and 12 (60%) with regular physical capacity or poor. As for TMRFB average values of initiation of muscle activation in 75% of subjects were within the limits to characterize the condition of pre-muscle activation. Conclusion:The results obtained in the TFF were low compared with the CFF of asymptomatic subjects evaluated. This fact does not mean that the condition of stabilization of the subject is appropriate. However, the results obtained in the electromyographic examination to suggest that 25% of asymptomatic subjects tested did not have a proper condition of lumbar stabilization.

Efeitos do treinamento resistido sobre secreação de testosterona e cortisol: uma revisão bibliográfica

You can set the resistance training such as making a move against a resistance by performing a muscle contraction and generating a muscular adaptation. This form of training, was initially used only in training athletes aiming to strengthen and improve fitness. Some coaches did not give proper focus, as the increase in muscle mass would cause loss of flexibility and agility. But over time a huge evolution occurred within this area and the practitioners of resistance training are no longer just athletes, and reached the whole community, from young to elderly, being a physical activity that generates a large caloric expenditure and has several health benefits, improve the cardiovascular system and decreasing the amount of body fat in the body. Cortisol is a hormone secreted from a stressful stimulus to the body, secretion undergoes control of the hypothalamic-pituitary axis, which releases the hormone into the bloodstream andrenocorticotrópico, going to the adrenal cortex responsible for their release. This has catabolic function, acting in the metabolism of carbohydrates, proteins and lipids, as well as having an important effect antiflamatório. Testosterone is a steroid hormone cholesterol from being produced by the testicles in men, as in women is produced to a lesser extent in ovary and adrenal glands, has functions androgenic and anabolic. Androgen function is responsible for the development of male sexual characteristics, while on anabolic function operates in the growth of muscles and bones, influencing the development of the human body organs. Within the metabolic changes that occur in the resistance training testosterone plays an important role in protein synthesis, influencing the production of strength and / or power during exercise. The objective of this work is through a literature review to assess the effects of resistance training on the production of these hormones and the relationship between them
