This study examined auditory temporal resolution as indexed by gap detection using the mismatch negativity (MMN) component of the auditory event-related potential (ERP) and its magnetic counterpart (MMNm). ERPs were recorded in 10 subjects who were presented with auditory stimuli. These stimuli were presented in sequences of repetitive continuous 'standard'(More)
There is a growing body of evidence showing that optical spectroscopy has the potential to be a useful in vivo diagnostic tool. Yet, so far there is no definitive cellular and biochemical understanding for the differences seen in the spectra from different tissue categories and disease states. In this study, we examine the use of organotypic raft cultures(More)
A treatment protocol is demonstrated, consisting of an osteotomy, either proximal or distal, of the bone defect with subsequent segmental transport via an anteromedially (tibia) or laterally (femur) mounted AO external fixation over an unreamed interlocking nail (monorail system). Twenty patients were treated by this method with indications as follows: 13(More)
The Apple-clearwing which is found in whole Europe, increases in importance in the last few years. The cater-pillars of the Apple-clearwing live unde the bark in the wood of as well old as young fruittrees. Investigations in 1976 and 1977 proved that a chemical control of the Apple-clearwing can be executed successfully either during the flightperiod of(More)
The Currant Clearwing Moth is a serious pest of currant and other soft fruit shrubs in the Netherlands intensifying damages since conditions of cultivating have been changed about ten years ago. Studies were made on bionomy and chemical control of this pest. Bait traps proved to be useful for recording the flight as well the quota of females but not for(More)
Continuous wave and pulsed laser ablation of tissue is described as an explosive event. A subsurface temperature maximum and superheated tissue produce high pressures that eject fragments from the tissue. Decreased water content due to dehydration and vaporization decreases thermal conductivity which reduces heat conduction. Also, a decrease in water(More)
The objective of this study was to evaluate glycerol (GLY) and GLY + dimethyl sulfoxide (DMSO) to increase photonic detection of transformed Salmonella typhimurium (S. typh-lux) through porcine skin. Skin was placed on 96-well plates containing S. typh-lux, imaged (5 min) using a CCD camera, and then completely immersed in PBS, GLY, DMSO, GLY+DMSO in a(More)
There exist two methods for the t reatment of port wine stains and other vascular malformations with yellow light lasers: namely, the short pulsed purpura producing method and the longer exposure time continuous wave (cw) or quasi-continuous wave blanching method. In the case of the pulsed dye lasers clinical results have shown continued improvement as the(More)
