Previous research has shown that there are strong constraints on the concurrent performance of nonharmonically related motor sequences such as polyrhythms. A model of polyrhythm production is proposed that involves a hierarchical timing system. The model assumes a single mechanism (a counter) for the timing and serial ordering of responses.

The expansion of both root hairs and pollen tubes occurs by a process known as tip growth. In this report, an Arabidopsis thaliana mutant (tip1) is described that displays defects in both root-hair and pollen-tube growth. The root hairs of the tip1 mutant plants are shorter than those of the wild-type plants and branched at their base. The tip1 pollen-tube(More)
The CYP2C gene cluster on chromosome 10q24 encodes the P450IIC enzymes, members of the cytochrome P450 monooxygenase superfamily. The P450-IIC enzymes are required for the metabolism of a number of foreign compounds, including the drugs mephenytoin and tolbutamide, and are also thought to be involved in the metabolism of endogenous steroid hormones. Several(More)
Chromosome band 10q24 is rich in genes involved in development, tumorigenesis, neurological disorders, hormone metabolism, and environmentally induced disease susceptibility. We have constructed an STS-based integrated physical and genetic map of 10q24 derived from the CEPH-Généthon mega-YAC contig data for this region. This map consists of 42 fluorescence(More)
The prevalence of Csh-like fibrillar surface proteins among oral streptococci was investigated by ELISA and by immunoelectron microscopy using antiserum raised to recombinant fragments of CshA of Streptococcus gordonii DL1. The majority of S. gordonii, Streptococcus sanguis and Streptococcus oralis strains tested elaborated short (ca. 50-80 nm long) surface(More)
OBJECTIVE Oral streptococci are primary colonisers of the tooth surface and are abundant in dental plaque biofilms. Bacteria growing in these relatively dense, surface-associated communities are phenotypically quite distinct from their planktonic counterparts. The purpose of the present study was to develop a method to investigate biofilm-specific surface(More)
Age-related macular degeneration (AMD) is a leading cause of legal blindness in the Western world. There are effective treatments for the vascular complications of neo-vascular AMD, but no effective therapies are available for the dry/atrophic form of the disease. A previously described transgenic CFH-gene deficient mouse model, (cfh-/-), shows hallmarks of(More)
Rearrangement of distal 10q is a common feature of many tumor types and tumor-derived cell lines. More specifically, loss of 10q23-25 has been demonstrated in a large proportion of prostate tumors, indicative of the presence of a tumor suppressor gene at this location. Using whole-chromosome paints and human genomic YAC clones as FISH probes, we have(More)
A panel of 93 radiation-reduced hybrids have been screened using PCR amplification and oligonucleotide primers for sequence-tagged sites (STSs) specific for 114 single-copy loci mapping to the short arm of chromosome 9. An x-ray dose of 6,000 rads gave an average retention frequency of approximately 23%. We have constructed a framework map containing 31(More)
