An interleukin 1 activity produced by peritoneal macrophages is increased with accelerated bone resorption in ovariectomized adult rats
Journal of Bone and Mineral Metabolism, 1991Co-Authors: Takashi MatsudaAbstract:Interleukin 1 (IL-1) is known to stimulate bone resorption in vitro and appears to influence the bone remodeling. Recently spontaneous release of IL-1 from blood monocytes was found to reflect bone formation in idiopathic osteoporosis. Since we developed the radiogrammetrical Longitudinal Method to quantitate the dynamic bone resorption rate in ovariectomized adult rats, the author has studied the relationship between bone resorption and IL-1 production by cultured peritoneal macrophages from adult rats. Endosteal bone resorption rate was accelerated in ovariectomized adult rate compared with sham-operated rats from 4 to 11 weeks after operations, as judged by radiogrammetrical Longitudinal study of the tibial cortex. Peritoneal macrophages from ovariectomized adult rats produced more IL-1 activity than sham-operated rats 6 weeks after operations. These results suggest that dynamic index of bone resorption was higher in ovariectomized adult rats with increased IL-1 activity. Thus, IL-1 may be responsible, at least in part, for the postovariectomy accelelation in bone resorption.

how does emotional exhaustion influence work stress relationships between stressor appraisals hedonic tone and fatigue in nurses daily tasks a Longitudinal cohort study
International Journal of Nursing Studies, 2017Co-Authors: Jordi Fernandezcastro, Fermin Martinezzaragoza, Tatiana Rovira, Angel Solanespuchol, Beatriz Martindelrio, Rosa Garciasierra, Gemma Benavidesgil, Eduardo DovalAbstract:Abstract Background Work-related stress is a prevalent condition in the nursing profession, and its influence may vary according to changeable individual and situational factors. It is, therefore, important to investigate the real-time momentary changes in these factors and their relationship to emotional exhaustion experienced by nurses. Objectives We aim to analyse how their perceptions of demand, control, effort and reward change according to the task performed through real-time assessment and interact with the emotional exhaustion level of ward nurses. Design The research design was Longitudinal. Method A three-level hierarchical model with a repeated measures design was used to assess the momentary self-reports of 96 hospital ward nurses, completed using a smartphone programmed with random alarms. Results Findings show that demand, effort, and control appraisals depend on the task performed. The task appraised as most demanding, effortful, and controllable was direct care. Reward appraisal depends on the task performed and personal variables, i.e. emotional exhaustion. The situations perceived as more rewarding were rest and direct care. Momentary hedonic tone can be explained by the task performed, demand, reward, emotional exhaustion and by the interaction between emotional exhaustion and demand appraisal. Momentary fatigue can be explained by the task performed, demand, reward, and the emotional exhaustion. Conclusions This study highlights the importance of using momentary measures to understand complex and changeable inter-relationships. While also clarifying the targets of intervention programmes aimed at preventing burnout within the nursing profession.

The influence of wood density on Longitudinal wave velocity determined by the ultrasound Method in comparison to the resonance Longitudinal Method
European Journal of Wood and Wood Products, 2011Co-Authors: Jan Baar, Jan Tippner, Vladimír GrycAbstract:The paper deals with the relationship between density and the velocity of sound wave propagation in wood. The wave velocity was measured using the heartwood of doussie (Afzelia bipindensis), merbau (Intsia bijuga), panga panga (Miletia stuhlmannii Taub.), tigerwood (Astronium graveolens Jacq.) and zebrano (Microberlinia brazzavillensis) by the two Methods: ultrasound and resonance Longitudinal. The velocity measured by the ultrasound Method was always higher than the values gained by the resonance Longitudinal Method. However, there is a high correlation between the results of both Methods. A change in sound wave velocity due to a change in density was not confirmed for any of the species. A similar conclusion was reached in the comparison among species.
