Introduction In the NOVA sodium and potassium analyser*, ion-selective electrodes measure sodium and potassium by direct potentiometry in separated plasma or serum or in the plasma phase of whole blood and in urine after dilution. Sodium is measured using a glass electrode and potassium using a valinomycin electrode. The sodium, potassium and reference electrodes all have a straight tube design...

The aim of this study was to investigate how the coordination patterns of shoulder muscles change with level-ground and incline wheelchair propulsion. Wheelchair kinetics and electromyography (EMG) activity of seven muscles were recorded with surface electrodes for 15 nondisabled subjects during wheelchair propulsion on a stationary ergometer and wooden ramp (4 degree slope). Kinetic data were ...

Relativistic magnetized jets, such as those from AGN, GRBs and XRBs, are susceptible to current- pressure-driven MHD instabilities that can lead particle acceleration non-thermal radiation. Here we investigate the development of these through 3D kinetic simulations cylindrically symmetric equilibria involving toroidal magnetic fields with electron-positron pair plasma. Generalizing recent treat...

UNLABELLED The goal in the current study was to examine the analgesic effects of a pinch grip-force production task and a working memory task when pain-eliciting thermal stimulation was delivered simultaneously to the left or right hand during task performance. Control conditions for visual distraction and thermal stimulation were included, and force performance measures and working memory perf...

BACKGROUND Particularly interesting new cysteine-histidine rich protein (PINCH), as an adapter protein of the LIM family for signal transduction in the integrin and growth factor pathway, is upregulated in the stroma of several common types of cancers and involved in promoting tumor progression. In the present study, we examined PINCH expression in normal endometrium, atypical endometrial hyper...

Particularly interesting new cysteine-histidine rich protein (PINCH), as a newly discovered protein of LIM family members, may play a role in signal transduction of integrin and growth factor, and involved in the incidence and development of tumors. PINCH protein is overexpressed in tumor-associated stroma of several types of tumors. However, there is no study of the PINCH in esophageal cancer,...

The purpose was to determine if pull-up performance was affected by the use of chalk (100% magnesium carbonate) during open-handed and pinch grip weight-assisted pull-ups (WAPU) in recreationally-trained rock climbers. Furthermore, the reliability of open-handed and pinch grip WAPU was also investigated. Recreationally-active volunteers (n = 9) completed six counterbalanced trials. Participants...

This study recruited 30 young Taiwanese males to determine the horizontally maximum isometric pushing and pulling strengths under 16 exertion heights and four handle-foot horizontal distances. This study shows that isometric push and pull strengths as measured on a simulated frictional floor condition in Taiwanese hypermarkets were markedly lower than previous tests using high-traction flooring...
