The aquaporin-4 (AQP4) pool in the perivascular astrocyte membranes has been shown to be critically involved in the formation and dissolution of brain edema. Cerebral edema is a major cause of morbidity and mortality in stroke. It is therefore essential to know whether the perivascular pool of AQP4 is up- or down-regulated after an ischemic insult, because(More)
BACKGROUND To identify fluid responsiveness, a correlation between respiratory variations in pulse pressure (DeltaPP) and respiratory variations in pulse oximetry photoplethysmographic waveform amplitude (DeltaPOP) in mechanically ventilated patients has been demonstrated. To evaluate the agreement between the two methods, knowledge about the repeatability(More)
In the past decades, microarray technology has definitely put an edge to the field of genetic research. Our aim was to determine whether single nucleotide polymorphism (SNP) microarrays could be used as a tool in establishing genetic relationships where current molecular genetic methods are not sufficient. We used the Genechip, Affymetrix GenomeWide SNP(More)
When assessing reliability of three dimensional gait analysis, the coefficient of multiple correlation (CMC), a measure of similarity of waveforms, is frequently used. Several shortcomings of the method have been reported. It is strongly related to the range of motion (ROM); it is supposed to take values from 0 to 1, but is known to obtain complex values(More)
Functional evidence suggests that neuronal enriched endosomal protein of 21 kDa (NEEP21) takes part in facilitating transport of AMPA receptors (AMPAR) in the synapse. To explore the anatomical basis for a role in this synaptic trafficking, we investigated the ultrastructural localization of NEEP21 in rodent brain. Using immunogold electron microscopy, we(More)
AMPA receptors have been identified in different populations of presynaptic terminals and found to be involved in the modulation of neurotransmitter release. The mechanisms that govern the expression of presynaptic AMPA receptors are not known. One possibility is that pre- and postsynaptic AMPA receptors are regulated according to the same principles. To(More)
INTRODUCTION Past studies indicate that lung function in professional divers, compared to non-divers, shows a reduction in maximal expiratory flow rates at low lung volumes and a reduction in the transfer factor for carbon monoxide. The objective in this study was to examine possible effects of long-term diving on pulmonary function among Norwegian(More)
BACKGROUND This study examines the possible effect of exposure to aerosols and gases on lung function in a fertilizer plant in Norway. METHODS Dynamic lung volumes (FVC and FEV1) of 383 workers were measured in 2007 and 2010. During the follow-up period, most workers performed tasks with low exposure levels of acid aerosols and inorganic gases. The(More)
Orofacial clefts are common birth defects with strong evidence for both genetic and environmental causal factors. Candidate gene studies combined with exposures known to influence the outcome provide a highly targeted approach to detecting GxE interactions. We developed a new statistical approach that combines the case-control and offspring-parent triad(More)
