| antigenic analysis of nonstructural protein (nsp) 4 of group a avian rotavirus strain po-13. | in order to analyze the antigenic structure of nonstructural protein (nsp) 4 of group a avian rotavirus strain po-13, 25 monoclonal antibodies (mabs) against nsp4 expressed in escherichia coli were produced. all mabs reacted with nsp4 on western blotting, indicating that they recognized sequential epitopes. to determine the antigenic sites (ass) recognized by the produced mabs, seven truncated nsp4s were expressed in e. coli. western blotting analysis showed that there are at least four major as ... | 2003 | 14584613 |

| inter- and intramolecular fluorescence quenching of organic dyes by tryptophan. | steady-state and time-resolved fluorescence measurements were performed to elucidate the fluorescence quenching of oxazine, rhodamine, carbocyanine, and bora-diaza-indacene dyes by amino acids. among the natural amino acids, tryptophan exhibits the most pronounced quenching efficiency. especially, the red-absorbing dyes atto 655, atto 680, and the oxazine derivative mr 121 are strongly quenched almost exclusively by tryptophan due to the formation of weak or nonfluorescent ground-state complexes ... | 2003 | 14624626 |
| acquired resistance of horses to amblyomma cajennense (fabricius, 1787) ticks. | acquired immunity of horses to larvae, nymphs and adults of the amblyomma cajennense tick was evaluated through three consecutive experimental infestations of tick-bite naïve hosts. data from these infestations were compared to those from field-sensitized horses and donkeys. it was observed that tick-bite naïve horses developed a low level of resistance after two infestations as shown by a significant decrease in larval yield and a tendency for lower engorged weight of nymphs during third infest ... | 2003 | 14637029 |

| [therapy with nonsteroidal anti-inflammatory drugs]. | nonsteroidal anti-inflammatory drugs (nsaids) are among the most frequently prescribed drugs worldwide. their analgetic and antiphlogistic effect results from an efficient inhibition of prostaglandin synthesis. the risk of side effects is remarkable. this concerns namely side effects in the gastrointestinal tract and the kidneys. the common nsaids inhibit both isoforms of the cyclooxygenase (cox). the analgetic and antiphlogistic effect results from the inhibition of cox-2, whereas the inhibitio ... | 2003 | 14655005 |

| peptide fragments of the dihydropyridine receptor can modulate cardiac ryanodine receptor channel activity and sarcoplasmic reticulum ca2+ release. | we show that peptide fragments of the dihydropyridine receptor ii-iii loop alter cardiac ryr (ryanodine receptor) channel activity in a cytoplasmic ca2+-dependent manner. the peptides were ac (thr-793-ala-812 of the cardiac dihydropyridine receptor), as (thr-671-leu-690 of the skeletal dihydropyridine receptor), and a modified as peptide [as(d-r18)], with an extended helical structure. the peptides added to the cytoplasmic side of channels in lipid bilayers at > or = 10 nm activated channels whe ... | 2004 | 14678014 |
| mild citrullinemia in caucasians is an allelic variant of argininosuccinate synthetase deficiency (citrullinemia type 1). | citrullinemia is caused by either deficiency of argininosuccinate synthetase (ass, citrullinemia type 1) or a defect of the slc25a13 gene encoding a mitochondrial aspartate-glutamate transporter (citrullinemia type ii). citrullinemia type 1-referred to as classical citrullinemia-is characterized by largely elevated concentrations of citrulline, manifesting with acute hyperammonemic crises predominantly early in life and occurs panethnically. citrullinemia type ii is a rare multisystem-disorder n ... | 2003 | 14680976 |
| fixed nucleotide differences on the y chromosome indicate clear divergence between equus przewalskii and equus caballus. | the phylogenetic relationship between equus przewalskii and e. caballus is often a matter of debate. although these taxa have different chromosome numbers, they do not form monophyletic clades in a phylogenetic tree based on mtdna sequences. here we report sequence variation from five newly identified y chromosome regions of the horse. two fixed nucleotide differences on the y chromosome clearly display przewalski's horse and domestic horse as sister taxa. at both positions the przewalski's hors ... | 2003 | 14687077 |

| a novel tricolor, dual-fusion fluorescence in situ hybridization method to detect bcr/abl fusion in cells with t(9;22)(q34;q11.2) associated with deletion of dna on the derivative chromosome 9 in chronic myelocytic leukemia. | dual-color, dual-fusion fluorescence in situ hybridization (d-fish) can accurately detect and quantify cells with bcr/abl fusion in <1% of 500 nuclei in 80% of patients with chronic myelocytic leukemia (cml) and t(9;22)(q34;q11.2). the remaining patients have one of three forms of atypical d-fish patterns; these patterns have different sensitivities to detect disease. neoplastic cells with one abl, one bcr, and one bcr/abl fusion are particularly problematic, because normal cells with coincident ... | 2004 | 14697634 |
| tetrahydrocortisol-apolipoprotein a-i complex specifically interacts with eukaryotic dna and gcc elements of genes. | tetrahydrocortisol stimulates dna and protein biosynthesis in hepatocytes only when it enters the complex with apolipoprotein a-i. tetrahydrocortisol-apolipoprotein a-i (thc-apoa-i) complex specifically interacts with eukaryotic dna isolated from rat liver. in the process of interaction, rupture of hydrogen bonds between the pairs of nitrous bases occurs with the formation of single-stranded dna structures. in such state dna forms complexes with dna-dependent rna-polymerase. the most probable si ... | 2003 | 14698212 |
| slc25a13-knockout mice harbor metabolic deficits but fail to display hallmarks of adult-onset type ii citrullinemia. | adult-onset type ii citrullinemia (ctln2) is an autosomal recessive disease caused by mutations in slc25a13, the gene encoding the mitochondrial aspartate/glutamate carrier citrin. the absence of citrin leads to a liver-specific, quantitative decrease of argininosuccinate synthetase (ass), causing hyperammonemia and citrullinemia. to investigate the physiological role of citrin and the development of ctln2, an slc25a13-knockout (also known as ctrn-deficient) mouse model was created. the resultin ... | 2004 | 14701727 |
| incidence and distribution of argininosuccinate synthetase deficiency in human cancers: a method for identifying cancers sensitive to arginine deprivation. | argininosuccinate synthetase (ass) was the first of two enzymes to convert citrulline to arginine. this pathway allowed cells to synthesize arginine from citrulline, making this amino acid nonessential for the growth of most mammalian cells. previous studies demonstrated that several human tumor cell lines were auxotrophic for arginine due to an inability to express ass. selective elimination of arginine from the circulation of animals with these tumors is a potentially effective anticancer trea ... | 2004 | 14770441 |
