Since the majority of protein-coding genes in vertebrates have intra-genomic homologues, it has been difficult to eliminate the potential of functional redundancy from analyses of mutant phenotypes, whether produced by genetic lesion or transient knockdown. Further complicating these analyses, not all gene products have activities that can be assayed in(More)
Using degenerate oligonucleotide primers, we isolated the Caenorhabditis remanei orthologue of the C. elegans sex-determining phosphatase gene fem-2 as well as two other protein phosphatase homologues. Despite the significant sequence divergence between C. elegans and C. remanei FEM-2, we used RNAi-mediated gene knockdown to demonstrate that at least some(More)
UNC-119 function is necessary for the correct development of the Caenorhabditis elegans nervous system. Worms mutant for unc-119 exhibit nervous system structural defects, including supernumerary axon branches, defasciculated nerve fibers, and choice point errors. Axons of both mechanosensory (ALM) and chemo- sensory (ASI) neurons have elongation defects(More)
OBJECTIVE Idiopathic normal pressure hydrocephalus (iNPH) is characterized by ventriculomegaly, gait difficulty, incontinence, and dementia. The symptoms can be ameliorated by CSF drainage. The object of this study was to identify factors associated with shunt-responsive iNPH. METHODS The authors reviewed the medical records of 529 patients who underwent(More)
The polarisation of ciliary bundles on the macula of the saccule in the European bass (Dicentrarchus labrax L) has been studied using a scanning electron microscope (SEM). These data show that D. labrax possesses ciliary bundles arranged in four dichotomous quadrants with a standard orientation, comparable to hearing generalists from the order Perciformes.(More)
