Fungal fimbriae are surface appendages that were first described on the haploid cells of the smut fungus, Microbotryum violaceum. They are long (1-20 microm), narrow (7 nm) flexuous structures that have been implicated in cellular functions such as mating and pathogenesis. Since the initial description, numerous fungi from all five phyla have been shown to(More)
A non-redundant database of nuclear, protein-encoding, genomic DNA sequences highlighting nuclear pre-mRNA introns was constructed using information contained in the SWISS-PROT and GenBank sequence databases. This Intron DataBase (IDB) contains information about (i) introns (including nucleotide sequence, location, phase, length, GC content and(More)
The sequence of a genomic clone encoding a 100-kDa stress protein of Plectonema boryanum (p-ClpB) was determined. The predicted polypeptide contains two putative ATPase regions located within two highly conserved domains (N1 and N2), a spacer region that likely forms a coiled-coil domain, and a highly conserved consensus CK2 phosphorylation domain. The(More)
Chaos game representation (CGR) is a novel holistic approach that provides a visual image of a DNA sequence quite different from the traditional linear arrangement of nucleotides. Although it is known that CGR patterns depict base composition and sequentiality, the biological significance of the specific features of each pattern is not understood. To(More)
The activity levels of CuZn superoxide dismutase (SOD) (SOD-1) and Mn SOD (SOD-2) in liver, kidney, and lung were assessed in newborn and 3-, 10-, 25-, and ∼70-week-old females from seven genetic strains (BALB/c, Csb, C3H/HeSnJ, C3H/S, C57BL/6J, Swiss-Webster, and 129/ReJ) of mice. Total SOD enzyme activity was high at birth and declined somewhat with old(More)
Tissue-specific catalase activity in 3-week-old animals from inbred mouse strains 129/ReJ, BALB/c, C3H/HeAnl/Cas-1b, C3H/HeSnJ, C3H/S, C57BL/6J, and Swiss-Webster was found to be highly variable by analysis of variance (P=0.01). Appropriate crosses were made among strains which were classified as normal (BALB/c, C3H/HeSnJ, C3H/S), hypocatalasemic (129/ReJ,(More)
Neuroendocrine tumors of the rectum constitute approximately 19 per cent of gastrointestinal neuroendocrine tumors (NETs). The histologic characteristics of the tumor seem to be an indicative prognostic factor. Optimal treatment of NETS of the rectum has been widely debated, but more recent studies suggest that treatment depends upon the size. The medical(More)
Recently, the incidence of bronchopulmonary carcinoid has increased substantially, whereas survival associated with both subtypes has declined. We reviewed our experience with bronchopulmonary carcinoid to identify factors associated with long-term survival. We reviewed our cancer registry from 1985 to 2009 for all patients undergoing surgical resection(More)
The effects of ethanol administered as a 15% solution in drinking fluid on weight gain, soluble liver protein and the activity of the three enzymes of oxygen radical metabolism (i.e., superoxide dismutase, catalase, and glutathione peroxidase) were studied in five inbred strains of mice (129/ReJ, BALB/c, C3H/HeSnJ, C57BL/6J, Csb) and Sprague Dawley rats,(More)
The catalase activity in the liver, kidney, lung, and blood hemolysate was measured in newborn, 21-, 70-, 175-, and greater than 400-day-old mice from the strains BALB/c, Csb, C3H/HeSnJ, C3H/S, C57BL/6J, SW, and 129/ReJ. Catalase activity was found to be highest in the liver (approximately 0.33 U/mg protein) followed by the kidney (approximately 0.13 U/mg(More)
