Barley stripe mosaic virus North Dakota 18 (ND18), Beijing (BJ), Xinjiang (XJ), Type (TY) and CV21 strains are unable to infect the Brachypodium distachyon Bd3-1 inbred line, which harbours a resistance gene designated Bsr1, but the Norwich (NW) strain is virulent on Bd3-1. Analysis of ND18 and NW genomic RNA reassortants and RNAβ mutants demonstrates that two amino acids within the helicase mo...
Recent advances in technology, computer architecture, and automated design environments have ushered in a new era of computer design in which large complex servers such as the S/390 G5 Parallel Enterprise ServerTM can be delivered with times to market once reserved for low-end systems such as single-user workstations and personal computers. Yet, the time to market is inversely proportional to c...
The vision of Palaemonetes is of particular interest in view of extensive studies of the responses of its chromatophore systems and eye pigments to light. The spectral sensitivity is here examined under conditions of dark adaptation and adaptation to bright colored lights. In each case the relative number of photons per one-fiftieth sec flash needed to evoke a constant peak amplitude (usually 2...
Chlorogenic acid was identified in the foliage of Douglas-fir during the dormant season. Concentrations varied among genotypes and ranged between 75 and 390 p.p.m. in the fresh tissue.
Background Reducing inappropriate antibiotic prescribing in primary care is a public health priority. Objectives We hypothesized that a subset of patients account for the majority of antibiotic prescriptions in primary care. We investigated the relationship between the total amount of antibiotics prescribed, individual-level antibiotic use and comorbidity. Methods This was a cohort study us...
The S/390@ floating-point unit (FPU) on the fourth-generation (G4) CMOS microprocessor chip has been implemented in a CMOS technology with a 0.20-pm effective channel length and has been demonstrated at more than 400 MHz. The microprocessor chip is 17.35 by 17.30 mm in size, and one copy of the FPU including the dataflow and control flow but not including the FPR register file is 5.3 by 4.7 mm ...
Tapeworms of the genus Spirometra are pseudophyllidean cestodes endemic in Korea. At present, it is unclear which Spirometra species are responsible for causing human infections, and little information is available on the epidemiological profiles of Spirometra species infecting humans in Korea. Between 1979 and 2009, a total of 50 spargana from human patients and 2 adult specimens obtained from...
Gamma-glutamyltranspeptidase (GGT) is an extracellular enzyme that plays a key role in glutathione metabolism. The mature GGT is a heterodimer consisting of L- and S-subunits that is generated by posttranslational cleavage of the peptide bond between Gln-390 and Thr-391 in the precursor protein. Thr-391, which becomes the N-terminal residue of the S-subunit, acts as the active residue in the ca...
