Infection of cervical epithelial cells with so-called "aggressive" subtypes of human papilloma virus (HPV) appears to be an important factor in the etiology of cervical carcinoma. However, mounting evidence suggests that additional genetic changes are required for progression to an invasive carcinoma. Functional studies have shown that human chromosome 11(More)
Detection of loss of heterozygosity (LOH) by comparison of normal and tumor genotypes using PCR-based microsatellite loci provides considerable advantages over traditional Southern blotting-based approaches. However, current methodologies are limited by several factors, including the numbers of loci that can be evaluated for LOH in a single experiment, the(More)
Although loss of heterozygosity (LOH) for loci on chromosome 3p is a common event in cervical carcinoma (CC), the frequency and affected regions of 3p are inconsistent among studies. Here we report a comprehensive analysis of LOH on 3p in 66 primary tumors and 16 CC-derived cell lines using a high density of marker loci. Clonal LOH was found in over 70% of(More)
Population density and size distribution, salinity tolerance, and feeding activity were examined in a western Pacific grapsid crab, Hemigrapsus sanguineus, that was recently introduced to the mid-Atlantic coast of North America. Seasonal abundance on a boulder/cobble shore (Crane Neck Pt.) in central Long Island Sound, New York, USA, during 1997–1998,(More)
Carcinomas of the uterine cervix are thought to arise from preinvasive dysplastic lesions, termed cervical intraepithelial neoplasias (CIN), grades I-III. Patients may present clinically with two or more distinct lesions of differing histological severity; however, the genesis of these multifocal lesions is unknown. Despite infection with high-risk human(More)
We examined emotional responses to standard affective pictures in 18 psychogenic nonepileptic seizure (PNES) patients. Given reports of trauma and posttraumatic stress symptoms (PTS) in many PNES patients, comparison groups were seizure-free individuals high and low in PTS (PTS-high, PTS-low; n=18 per group). Patients with psychogenic nonepileptic seizures(More)
Pre-mRNA splicing is an essential component of eukaryotic gene expression and is highly conserved from unicellular yeasts to humans. Here, we present the development and implementation of a sequencing-based reverse genetic screen designed to identify nonessential genes that impact pre-mRNA splicing in the fission yeast Schizosaccharomyces pombe, an organism(More)
Infection of epithelial cells with human papillomavirus is an important early event in the development of cervical dysplasia. However, progression to overt malignancy appears dependent upon further genetic and/or epigenetic events. We have recently developed methodologies for the simultaneous analysis of loss of heterozygosity (LOH) at multiple PCR-based(More)
Karyotypic and molecular data indicate that genetic alterations of the long arm of chromosome 11 (11q) may be involved in malignant melanoma. To test this we analyzed 5 polymorphic microsatellite repeats on 11q using a PCR-based assay for loss of heterozygosity in normal and tumor tissues from 24 individuals with cutaneous malignant melanoma of various(More)
We performed an experiment to test the effects of adult density on the growth rates of juvenile Polydora cornuta. Our experiment was performed in three identical counter-rotating annular flumes, each set to one of three different flow speeds for a period of 3 d (U 5mm ϭ 3, 6, or 12 cm s Ϫ1 , where U 5mm ϭ velocity measured 5 mm above bottom). We implanted(More)
