Energy cost of resistance exercises: an uptade.

The use of resistance exercises and of typical strength training methods have been progressively used to control body mass and to promote fat mass loss. The difficulties involved in the energy cost calculation during strength training are associated with the large amount of exercises and their several variations. Mean values between ≈3 and 30 kcal·min(-1) are typically reported but our studies indicate that it may attain values as high as 40 kcal·min(-1) in exercises which involve a large body mass.

Influence of the number of sets at a strength training in the flexibility gains.

The aim of this study was to investigate the effects of 10 weeks of strength training with different number of sets and their influence on flexibility of young men. Sixty men were divided into three groups as follows: group that trained 1 set per exercise (G1S), group that trained 3 sets per exercise (G3S) and control group (CG). The training lasted 10 weeks, totaling 30 training sessions.

Application of fibrin glue in microvascular anastomoses: comparative analysis with the conventional suture technique using a free flap model.

Background: Several studies have already reported the utilization of fibrin glue in microvascular anastomoses to minimize the number of sutures and to decrease the operative time. Despite the good results obtained in most of these experiments, its clinical application has not launched. The aim of this study was to clarify the controversies around the safeness of fibrin glue application in microvascular anastomoses, and also to demonstrate the potential benefits of fibrin glue application in a realistic free flap model.

Effect of fibrin adhesive application in microvascular anastomosis: a comparative experimental study.

Background: Microvascular anastomosis is the most critical step during free flap transfers or replantations. Although the conventional suture is still considered the standard technique, it is technically difficult, time consuming, and traumatic to the vessel wall. The aim of this study was to evaluate the effectiveness of fibrin adhesive to overcome these problems when applied in microvascular anastomosis.

Effects of antidepressant treatment on cognitive performance in elderly subjects with heart failure and comorbid major depression: an exploratory study.

Cognitive deficits are common in association with heart failure (HF), and it is possible that their severity is magnified by the concomitant presence of major depressive disorder (MDD). Using the Cambridge Mental Disorders of the Elderly Examination battery, the authors compared the cognitive performance of MDD-HF subjects (N=20), nondepressed HF subjects (N=23), and healthy control subjects (N=18). Scores were lower in both HF groups relative to control subjects.
