Electro-osmotic pumping (EOP) theory and its characteristics (transport numbers, brine concentration, current density, current efficiency, electro-osmotic coefficients, etc.) of Selemion AMV and CMV ion-exchange membranes were studied. The brine concentration increased with increase in current density and feed water concentration. Current efficiency was nearly constant in a wide range of curren...

Oxidative base damage in DNA and metabolic defects in the recognition and removal of such damage play important roles in mutagenesis and human disease. The extent to which cellular RNA is a substrate for oxidative damage and the possible biological consequences of RNA base oxidation, however, remain largely unexplored. Since oxidatively modified RNA may contribute to the high mutability of retr...

The genome of the avian myeloblastosis virus (AMV) has undergone a sequence substitution in which a portion of the region normally coding for the env protein has been replaced by cellular sequences. We have determined the complete nucleotide sequence of this region. Examination of the AMV oncogenic sequence revealed an open reading frame starting with the initiation codon ATG and terminating wi...

The covalent linkage of oncornavirus-specific DNA to chicken DNA was investigated in normal chicken embryo fibroblasts (CEF) and in virus-producing leukemic cells transformed by avian myeloblastosis virus (AMV). The virus-specific sequences present in cellular DNA fractionated by different methods were detected by DNA-RNA hybridization by using 70S AMV RNA as a probe. In CEF and in leukemic cel...

8-Nitro-2'-deoxyguanosine (8-nitrodG) is a relatively unstable, mutagenic lesion of DNA that is increasingly believed to be associated with tissue inflammation. Due to the lability of the glycosidic bond, 8-nitrodG cannot be incorporated into oligodeoxynucleotides (ODNs) by chemical DNA synthesis and thus very little is known about its physicochemical properties and base-pairing preferences. He...

Faba bean is a major grain legume widely cultivated in many countries.There are a large number of viruses damaging faba bean crop. In this survey, during 2011-2012 growing seasons, to determine the distribution of Bean yellow mosaic virus (BYMV), Bean common mosaic virus (BCMV), Cucumber mosaic virus (CMV), Tomato spotted wilt virus (TSWV) and Alfalfa mosaic virus (AMV), 630 samples were collec...

In the proximal tubule, the apical Na(+)/H(+) exchanger identified as NHE3 mediates most NaCl and NaHCO(3) absorption. The purpose of this study was to analyze the long-term regulation of NHE3 during alkalosis induced by dietary NaHCO(3) loading and changes in NaCl intake. Sprague-Dawley rats exposed to a low-NaCl, high-NaCl, or NaHCO(3) diet for 6 days were studied. Renal cortical apical membr...

Communication, Ocean and Meteorological Satellite (COMS) is the first Korean geostationary satellite, which is located in 128.2°E launched in 2010, and it is currently under normal operation. Atmospheric motion vectors (AMVs) derived with high resolution satellite images are useful for analyzing mesoscale motion such as convective clouds and ageostrophic flow. National Institute of Meteorologic...

RNAs 1 and 2 of the tripartite genome of alfalfa mosaic virus (AMV) encode the replicase proteins P1 and P2, respectively. P1 contains a methyltransferase-like domain in its N-terminal half, which has a putative role in capping the viral RNAs. Six residues in this domain that are highly conserved in the methyltransferase domains of alphavirus-like viruses were mutated individually in AMV P1. No...
