Reduction of diameter of the left ventricle of dogs by plication of the left ventricular free wall

Objective - To determine effects of reducing the diameter of the left ventricle of dogs by plication of the left ventricular free wall. Animals - 8 healthy adult mixed-breed dogs. Procedure - Left lateral thoracotomy and a T-shaped pericardiotomy were performed. The free wall of the left ventricle was imbricated with 3 interrupted transfixing sutures applied in a horizontal mattress pattern, using 3-0 polypropylene suture assembled on a straight cutting needle. Surgeons were careful to avoid the coronary vessels. Echocardiography was performed 24 hours before and 48 hours after surgery. Electrocardiography was performed before and 1, 2, 7, 15, 21, 30, and 60 days after surgery. Results - Echocardiographic measurements revealed that the diameter of the left ventricle was reduced by a mean of 23.5%. Electrocardiography revealed ventricular premature complexes 24 hours after surgery that regressed without treatment during the first week after surgery. Conclusions and Clinical Relevance - Plication of the left ventricular free wall of dogs can reduce end-diastolic and end-systolic dimensions of the left ventricle. The technique is simple and does not require cardiopulmonary bypass. According to Laplace's law, the reduction of cardiac diameter leads to reduction on free-wall tension and may improve left ventricular function in dilatated hearts. Thus, additional studies involving dogs with dilated cardiomyopathy should be conducted.

Fermented soy product supplemented with isoflavones affected fat depots in juvenile rats

Objectives: This study investigated the effects of soy product fermented by Enterococcus faecium and Lactobacillus jugurti supplemented with isoflavones on adipose tissue, blood lipid, and glucose levels on juvenile rats. Methods: Rats were fed a cholesterol-enriched diet for 3 wk as a preliminary treatment to create hypercholesterolemia. They were then fed a chow diet (HC), a chow diet plus fermented soy product supplemented with isoflavones (HCFI), a chow diet plus placebo (HCP), or a chow diet plus placebo supplemented with isoflavones (HCPI), respectively, for an additional 3 wk. Results: The beneficial effects of fermented soy product supplemented with isoflavones on epididymal (EPI) and retroperitoneal (RET) fat pads was likely due to isoflavones because adipocyte circumference (micrometers) in the HC group was significantly larger (EPI: 105.66 ± 13.36; RET: 134.95 ± 25.40) than that in the HCFI group (EPI: 93.17 ± 12.80; RET: 108.62 ± 15.50) and HCPI group (EPI: 93.06 ± 15.10; RET: 112.34 ± 18.21). The probiotic micro-organism accentuated the antilipogenic effect of isoflavones on RET (HCFI: 108.62 ± 15.50 micrometers versus HCPI: 112.34 ± 18.21 micrometers). Moreover, the fermented product increased glucose concentration similar to that in the chow group but did not change blood lipids. Conclusion: This product may offer new approaches to obesity prevention. © 2005 Elsevier Inc. All rights reserved.

Trabalho de docência e comportamento micro-organizacional: A motivação do docente na área da saúde

Using the motivograma and interviews the degree of motivation of the survey participants was defined as satisfactory. On one hand there is satisfaction with the physiological needs, self-esteem and self confidence, on the other there is high dissatisfaction with the association and self-realization, justifying the request for strengthening the membership and performance improvements in the research area. Linking up security and association with the other ones group protection sentiments and work environment dependence sentiments prevail. It was concluded that: (1) Those satisfied ones declare that they are safe, protected and with good self-esteem doing their teaching work. The ones dissatisfied with the non-group belonging demonstrate dissatisfaction with the self-realization and expose their difficulties with social ties and the lack of integration in the teaching work. (3) The degree of motivation satisfactory is related to the satisfaction of basic needs, located in the first steps of Maslow's hierarchy. Accepting that the changes in higher education require motivated behaviors, the question arises: how can the motivation in teaching work be possible if the majority of organizations do not find a way to deal with the person of the Professor? Finally, the context of work is predominant in the provision of job satisfaction in teaching.

A escrita de si na formação em educação física

The Self-writing on the formation in Physical Education Abstract: The objective of this article is to create a field of quarrels about Self-writing on the context of professional graduation in Physical Education, recognizing this writing exercise as a potential way to find what escapes to the knowledge terms and that force the thought to think the consistency of the meeting that across the graduation process. From this point, we want to reach the demands that are excluded in the formation speech - the demands of sensibility - recognizing them as expressions of an incarnate knowledge. Beyond the theoretical skills, the Selfwriting helps us to build a deeper understanding of the professional graduation, not because it play on a speech upon the practices, but for giving opening to the writing of the intensities forged in the meeting between practice and knowledge - where the professional intervention is installs.

Cidade e antíteses: uma leitura do romance Passagem dos Inocentes de Dalcídio Jurandir

Este trabalho não pretende discutir as inúmeras leituras que as obras de Dalcídio Jurandir vem merecendo ao longo dos anos; deseja, tão somente, apresentar uma proposta de leitura do romance Passagem dos Inocentes, na perspectiva do Materialismo histórico-dialético. A ênfase do trabalho reside na metáfora que aproxima semanticamente o título do romance ao processo de emancipação crítica verificado em seu protagonista. As fases dialéticas da tese, antítese e síntese, no processo de auto-realização verificado em Alfredo, processam-se numa cadeia contínua a partir dos seguintes estágios: ilusão ideológica; decepção com a urbs e, por último, auto-realização com a construção de um percurso contrário a urbs.

Contribuição da amplitude de movimento articular do joelho na marcha de crianças com paralisia cerebral espástica

Individuals with spastic cerebral palsy show muscle weakness, difficulties in the control of agonist and antagonist muscles, decreased range of motion and tonus and sensibility alterations, especially in knee joint. These problems can interfere on the performance of functional activities such gait. The aim of this study was to analyze the contribution of knee range of motion on gait of hemiplegic and diplegic children considering their asymmetries. Twelve children, 6 hemiplegics e 6 diplegics from 7 to 12 years of age (age average= 9,5 ± 1,93) took part. Spasticity was assessed by the Ashworth’s Modified Scale and the passive knee range of motion by an eletrogoniometer. The task was to walk on a walkway of 8m long, in their preferred speed, in 6 attempts, been 3 on right and 3 on left sagital planes. Eigth passive markers were bilaterally fixed for the kinematic record. Orthogonally to the walkway, two digital camcorders were assembled on the sagital plane. The fotogrametric procedures were performed by the Dvideow 6.3 software. The Matlab 7.0.1 software was used to filter and to calculate the dependent variables. The U test of Mann- Whitney found differences to the cerebral palsy type for knee extension/hiperextension (U = - 2.943; p= 0.003), knee relative angle at heel contact (U = - 5.992; p= 0.001) and knee range during stride (U = - 4.099; p= 0.001). The Wilcoxon’s test revealed differences according to the asymmetries for the hemiplegics only for the knee relative angle at heel contact (T= - 2.635; p<0.008). The contributions of passive knee range of motion, revealed by the Spearman correlations, for the more afected limb of the diplegics, showed that the knee extension/hiperextension interfere on the cadence, stride duration and step width; the knee relative angle at heel contact change the stride length and duration and cadence; and the...(Complete abstract click electronic access below)
