Influência do bloqueador de receptor de angiotensina (Losartana potássica) na função renal e pressão arterial em cães GRMD

A distrofia muscular de Duchenne (DMD) é uma alteração neuromuscular caracterizada por contínua necrose muscular e degeneração, com eventual fibrose e infiltração por tecido adiposo. O aumento progressivo da fibrose intersticial no músculo impede a migração das células miogênicas, necessárias para a formação muscular. O modelo canino constitui-se nas melhores fenocópias da doença em humanos, quando comparados com outros modelos animais com distrofia. O tratamento antifibrose de pacientes DMD, tendo como alvo os mediadores da citocina, TGF-beta, e o tratamento com antiinflamatórios, podem limitar a degeneração muscular e contribuir para a melhora do curso da doença. O presente estudo teve como objetivo observar os possíveis efeitos adversos na fisiologia renal, por meio de avaliação bioquímica sanguínea e da pressão arterial, verificando a viabilidade do uso do Losartan (um inibidor de TGF-beta) nos cães afetados pela distrofia muscular. Foram utilizados quatro cães adultos, sendo dois machos e duas fêmeas. Utilizou-se a dose de 50mg de Losartan, administrada via oral, uma vez ao dia. Os exames clínicos, bem como alterações na função renal, o nível do potássio sérico e a pressão arterial não evidenciaram reação adversa durante todo o período do experimento. O uso de Losartan, por um período de 9 semanas, mostrou-se como uma terapia segura para o tratamento antifibrótico em cães adultos, não afetando a função renal ou pressão arterial dos animais.

A dança «en-cena» o outro: prerrogativas para uma educação estética através do processo criativo

The dance installs in the body another scene of senses that raises the creative performance and not that can be speculated about it. There, ""who dance"" is the Other one, making the body acting of another manner, beyond the systemic contour of Ego. Without the presence of this forged performance, the body would not pass of one ruled machine in function of something and not in favor of himself, as original movement of himself. This article intends to make a reflection about the corporal perception in the dance, trying to point out the creative performance. So, we opened a way to understand the process creative as field of corporal sensitization where the educative intervention is accomplished in the body.

Class II Correction with the Cantilever Bite Jumper

Objective: To identify the skeletal, dentoalveolar, and soft tissue changes that occur during Class II correction with the Cantilever Bite Jumper (CBJ). Materials and Methods: This prospective cephalometric study was conducted on 26 subjects with Class II division 1 malocclusion treated with the CBJ appliance. A comparison was made with 26 untreated subjects with Class II malocclusion. Lateral head films from before and after CBJ therapy were analyzed through conventional cephalometric and Johnston analyses. Results: Class II correction was accomplished by means of 2.9 mm apical base change, 1.5 mm distal movement of the maxillary molars, and 1.1 mm mesial movement of the mandibular molars. The CBJ exhibited good control of the vertical dimension. The main side effect of the CBJ is that the vertical force vectors of the telescope act as lever arms and can produce mesial tipping of the mandibular molars. Conclusions: The Cantilever Bite Jumper corrects Class II malocclusions with similar percentages of skeletal and dentoalveolar effects. (Angle Orthod. 2009:79;)

Programmable diagnostic devices made from paper and tape

This paper describes three-dimensional microfluidic paper-based analytical devices (3-D mu PADs) that can be programmed (postfabrication) by the user to generate multiple patterns of flow through them. These devices are programmed by pressing single-use 'on' buttons, using a stylus or a ballpoint pen. Pressing a button closes a small space (gap) between two vertically aligned microfluidic channels, and allows fluids to wick from one channel to the other. These devices are simple to fabricate, and are made entirely out of paper and double-sided adhesive tape. Programmable devices expand the capabilities of mu PADs and provide a simple method for controlling the movement of fluids in paper-based channels. They are the conceptual equivalent of field-programmable gate arrays (FPGAs) widely used in electronics.

Joint forces and torques when walking in shallow water

This study reports for the first time an estimation of the internal net joint forces and torques on adults` lower limbs and pelvis when walking in shallow water, taking into account the drag forces generated by the movement of their bodies in the water and the equivalent data when they walk on land. A force plate and a video camera were used to perform a two-dimensional gait analysis at the sagittal plane of 10 healthy young adults walking at comfortable speeds on land and in water at a chest-high level. We estimated the drag force on each body segment and the joint forces and torques at the ankle, knee, and hip of the right side of their bodies using inverse dynamics. The observed subjects` apparent weight in water was about 35% of their weight on land and they were about 2.7 times slower when walking in water. When the subjects walked in water compared with walking on land, there were no differences in the angular displacements but there was a significant reduction in the joint torques which was related to the water`s depth. The greatest reduction was observed for the ankle and then the knee and no reduction was observed for the hip. All joint powers were significantly reduced in water. The compressive and shear joint forces were on average about three times lower during walking in water than on land. These quantitative results substantiate the use of water as a safe environment for practicing low-impact exercises, particularly walking. (C) 2011 Elsevier Ltd. All rights reserved.

Simplified models for cross-section stress demands on C-section purlins in uplift

The objective of this paper is to provide and verify simplified models that predict the longitudinal stresses that develop in C-section purlins in uplift. The paper begins with the simple case of flexural stress: where the force has to be applied at the shear center, or the section braced in both flanges. Restrictions on load application point and restraint of the flanges are removed until arriving at the more complex problem of bending when movement of the tension flange alone is restricted, as commonly found in purlin-sheeting systems. Winter`s model for predicting the longitudinal stresses developed due to direct torsion is reviewed, verified, and then extended to cover the case of a bending member with tension flange restraint. The developed longitudinal stresses from flexure and restrained torsion are used to assess the elastic stability behavior of typical purlin-sheeting systems. Finally, strength predictions of typical C-section purlins are provided for existing AISI methods and a newly proposed extension to the direct strength method that employs the predicted longitudinal stress distributions within the strength prediction.
