Active sitting with backrest support: Is it feasible?

Ergonomics science recommends office chairs that promote active sitting to reduce sitting related complaints. Since current office chairs do not fulfill this recommendation, a new chair was developed by inverting an existing dynamic chair principle. This study compares active sitting on the inverted chair during a simulated computer-based office task to two existing dynamic office chairs (n = 8).

Effects of stress on women's preference for male facial masculinity and their endocrine correlates.

Women's preferences for masculinity in men's faces seem to vary across the menstrual cycle and are assumed to be strongest around ovulation. A number of hormones have been proposed to underlie these subtle cyclic shifts. Furthermore, mating preferences are context-dependent, and stress has been found to alter mate choice, both in animals and humans.

Towards the development of a novel experimental shoulder simulator with rotating scapula and individually controlled muscle forces simulating the rotator cuff.

A preclinical analysis of novel implants used in shoulder surgery requires biomechanical testing conditions close to physiology. Existing shoulder experiments may only partially apply multiple cycles to simulate postoperative, repetitive loading tasks. The aim of the present study was therefore the development of an experimental shoulder simulator with rotating scapula able to perform multiple humeral movement cycles by simulating individual muscles attached to the rotator cuff.

[Vocational rehabilitation of the mentally ill - an evaluation of the Vocational Rehabilitation Center in Zurich, Switzerland].

Objective: The aim of the Vocational Rehabilitation Center in Zurich (VRC) is to reintegrate mentally ill persons into the primary labour market, mainly by prevocational training followed by continuous professional support for employed individuals. The present study evaluated the impact of the VRC.

Methods: The job and financial situation of 68 trained persons was assessed up to two years after the training.

Penetration of fleroxacin into human lung, muscle, and fat tissue.

Fleroxacin is a new fluoroquinolone with established potent antimicrobial and pharmacokinetic properties, and the aim of this study was to determine its rate of penetration into human lung, muscle, and fat tissues. In a total of eight patients undergoing lung surgery, plasma and tissue concentrations of unmetabolized fleroxacin were determined. This was done in subgroups of two patients each, receiving either 6, 8, 12 or 24 hours prior to surgery one single oral dose of 400 mg fleroxacin.
