Knowledge and willingness to teach cardiopulmonary resuscitation: a survey amongst 4273 teachers.

INTRODUCTION Schoolteachers are expected to play a role in teaching cardiopulmonary resuscitation (CPR) to schoolchildren, but little is known about their attitudes, actual knowledge and willingness to do so. We conducted a survey about CPR knowledge, preparedness to perform and teach CPR as well as attitude towards an alternative self-learning strategy amongst Flemish teachers. METHODS A que...

A simple device for multiplex ELISA made from melt-extruded plastic microcapillary film.

We present a simple device for multiplex quantitative enzyme-linked immunosorbant assays (ELISA) made from a novel melt-extruded microcapillary film (MCF) containing a parallel array of 200 μm capillaries along its length. To make ELISA devices different protein antigens or antibodies were immobilised inside individual microcapillaries within long reels of MCF extruded from fluorinated ethylene...

Astrocyte-derived BDNF supports myelin protein synthesis after cuprizone-induced demyelination.

It is well established that BDNF may enhance oligodendrocyte differentiation following a demyelinating lesion, however, the endogenous sources of BDNF that may be harnessed to reverse deficits associated with such lesions are poorly defined. Here, we investigate roles of astrocytes in synthesizing and releasing BDNF. These cells are known to express BDNF following injury in vivo. In culture, th...

Adaptation changes stereoscopic depth selectivity in visual cortex.

Exposure to specific visual stimuli causes a reduction in sensitivity to similar subsequent stimulation. This adaptation effect is observed behaviorally and for neurons in the primary visual cortex. Here, we explore the effects of adaptation on neurons that encode binocular depth discrimination in the cat's primary visual cortex. Our results show that neuronal preference for binocular depth is ...
