INTRODUCTION Subperiosteal preparation using a periosteal elevator leads to disturbances of local periosteal microcirculation. Soft-tissue damage can usually be considerably reduced using piezoelectric technology. For this reason, we investigated the effects of a novel piezoelectric device on local periosteal microcirculation and compared this approach with the conventional preparation of the p...

Nowadays, most of the main companies in the vertical transport industry are researching tools capable of providing support for the design process of elevator systems. Numerous decisions have to be taken to obtain an accurate, comfortable, and high-quality service. Effectively, the optimization algorithm is a key factor in the design process, but so are the number of cars being installed, their ...

Fine particles derived from diesel engines, diesel exhaust particles (DEP), have been shown to augment gene expression of several inflammatory cytokines in human airway epithelial cells in vitro. However, it remains unclear whether or not DEP have any effect on the expression and production of eotaxin, an important chemokine involved in eosinophil recruitment into the airways. We studied the ef...

aircraft regarding to the elevator deflection angle is designed. The way how the elevator angle affects pitching motion of the aircraft is pointed out, as well as, how a pitch controller can be applied for the aircraft to reach certain pitch angle. In this digital optimal system, the elevator deflection angle and pitching angle of the plane are considered to be input and output respectively. A ...

An elevator configuration task, the VT task, is modelled within DESIRE as a design task. DESIRE is a framework within which complex reasoning tasks are modelled as compositional architectures. Compositional architectures are based on a task decomposition, acquired during task analysis. An earlier developed generic task model of design, based on a logical analysis and synthesis of task models de...

Diesel exhaust particles (DEP) are known to enhance inflammatory responses in human volunteers. In cultured human bronchial epithelial (16HBE) cells, they induce the release of proinflammatory cytokines after triggering transduction pathways, including nuclear factor (NF)-kappaB activation and mitogen-activated protein kinase (MAPK) phosphorylation. This study compares the effects of native DEP...

Diesel exhaust particles (DEP) induce pulmonary diseases including asthma and chronic bronchitis. Comprehensive evaluation is required to know the effects of pollutants including DEP on these and other lung diseases. Alveolar macrophages (AM) and epithelial cells are important cellular targets for pollutants such as DEP in the lung. Alveolar macrophages encounter and phagocytose DEP in the alve...

BACKGROUND The purpose of this study was to consider the mechanism of isolated oculomotor nerve palsy after minor head trauma. CASE DESCRIPTION We report a rare case of delayed and isolated oculomotor nerve palsy following minor head trauma. A 19-year-old boy complained of double vision 1 day after a minor head trauma. Neuro-ophthalmic examination showed isolated left oculomotor nerve palsy. ...

BACKGROUND C5 palsy is a serious but poorly understood complication after posterior cervical decompression that could lead to muscle weakness, brachialgia and numbness of the upper limbs. The incidence of C5 palsy varies greatly between studies. The risk factors are inconclusive and even conflicting. OBJECT To perform a systematic review on the incidence and risk factors of C5 palsy after pos...

Twenty-four hours of maternal deprivation result in activation of the infant rat's adrenocortical axis. In the present study we examined the long-term effects of maternal deprivation on the corticosterone (Cort) response to stress. Pups were maternally deprived (Dep) on postnatal day( PND) 11 and tested immediately ( PND 12) or returned to their mothers and tested at later ages. Testing consist...
