A 200-300 kb region of chromosome 3p14.2, including the fragile site locus FRA3B, is homozygously deleted in multiple tumor-derived cell lines. Exon amplification from cosmids covering this deleted region allowed identification of the human FHIT gene, a member of ther histidine triad gene family, which encodes a protein with 69% similarity to an S. pombe(More)
We have re-evaluated the conditions for preparing competent Escherichia coli cells and established a simple and efficient method (SEM) for plasmid transfection. Cells (DH5, JM109 and HB101) prepared by SEM are extremely competent for transformation (1-3 x 10(9) cfu/microgram of pBR322 DNA), and can be stored in liquid nitrogen for at least 40 days without(More)
Bisphenol A, an environmental oestrogenic chemical, was found to conjugate highly with glucuronic acid in male rat liver microsomes studied in vitro. In the various isoforms tested (1A1, 1A3, 1A5, 1A6, 1A7 and 2B1), glucuronidation of bisphenol A and of diethylstilboestrol, a synthetic crystalline compound possessing oestrogenic activity and known to be(More)
The DNA polymerase gene from the archaeon Pyrococcus sp. strain KOD1 (KOD DNA polymerase) contains a long open reading frame of 5,013 bases that encodes 1,671 amino acid residues (GenBank accession no. D29671). Similarity analysis revealed that the DNA polymerase contained a putative 3'-5' exonuclease activity and two in-frame intervening sequences of 1,080(More)
Wolfram syndrome (WFS; OMIM 222300) is an autosomal recessive neurodegenerative disorder defined by young-onset non-immune insulin-dependent diabetes mellitus and progressive optic atrophy. Linkage to markers on chromosome 4p was confirmed in five families. On the basis of meiotic recombinants and disease-associated haplotypes, the WFS gene was localized to(More)
Sixteen marine methanotrophic bacteria were isolated and 14 marine methanotrophic mixed cultures were obtained. They were assayed for soluble methane monooxygenase (sMMO) by naphthalene oxidation and only one isolate (strain NI) was positive. Strain NI degraded trichloroehylene (TCE) more efficiently than other methanotrophic isolates containing no sMMO(More)
There are few DNA-based studies that detect cancer micrometastases in lymph nodes. We have assayed for the specific detection of carcinoembryonic antigen (CEA)-expressing carcinoma cells in the lymph nodes of patients with gastrointestinal or breast carcinomas. A CEA-specific nested reverse transcriptase (RT)-PCR assay was optimized using limiting dilutions(More)
We determined whether resveratrol, a phenolic antioxidant found in grapes and other food products, inhibited phorbol ester (PMA)-mediated induction of COX-2 in human mammary and oral epithelial cells. Treatment of cells with PMA induces COX-2 and causes a marked increase in the production of prostaglandin E2. These effects were inhibited by resveratrol.(More)
Many sorting algorithms have been studied in the past, but there are only a few algorithms that can effectively exploit both SIMD instructions and thread-level parallelism. In this paper, we propose a new parallel sorting algorithm, called aligned-access sort (AA-sort), for shared-memory multi processors. The AA-sort algorithm takes advantage of SIMD(More)
