identification and characterization of mg2+-dependent phosphotyrosyl protein phosphatase from rat liver cytosol. | although highly purified preparations of mg2+-dependent phosphoseryl protein phosphatase (also designated phosphatase ia or phosphatase 2c) dephosphorylated phosphotyrosyl histone, the activity has been resolved from phosphatase ia by polyacrylamide gel electrophoresis at ph 9.5. this novel phosphotyrosyl-specific protein phosphatase absolutely requires mg2+ or mn2+ for activity, is inhibited by zn2+, vanadate and fluoride, and has an optimal ph of 9.0 and mr = 50,000. certain properties of this ... | 1986 | 3022716 |
thymidine kinase with altered substrate specificity of acyclovir resistant varicella-zoster virus. | the acyclovir resistant mutant of varicella-zoster virus acv-r (a 8) induced the same level of thymidine kinase activity in infected cells as the parent kawaguchi strain. however, it induced less deoxycytidine kinase activity and did not induce phosphorylating activity for the nucleotide analogue, 9-(2 hydroxy-ethoxymethyl)-guanine-(acyclovir). another acyclovir resistant mutant, acv-r (a 4), which is cross-resistant to phosphonoacetate and is thought to be a viral dna polymerase mutant, induced ... | 1986 | 3022711 |
spermine antagonises the effects of dexamethasone, glucagon and cyclic amp in increasing the activity of phosphatidate phosphohydrolase in isolated rat hepatocytes. | rat hepatocytes were incubated in monolayer culture, under serum free conditions, for 8 h. glucagon (10 nm), 8-(4-chlorophenylthio)adenosine 3',5'-cyclic monophosphate (100 microm) and dexamethasone (100 nm) increased the activity of phosphatidate phosphohydrolase by approx. 2-, 3.6- and 3.3-fold, respectively. spermine alone had no significant effect. spermine (2.5 mm) almost completely inhibited the glucagon induced increase in phosphohydrolase activity. it only partially inhibited the dexamet ... | 1986 | 3021529 |
eicosapentaenoic acid inhibits synthesis and secretion of triacylglycerols by cultured rat hepatocytes. | primary cultures of rat hepatocytes were used to study the effects of eicosapentaenoic and oleic acid on synthesis and secretion of triacylglycerols associated with very low density lipoproteins. from the experiments the following was observed. oleic acid markedly stimulates secretion as well as synthesis of triacylglycerols, whereas eicosapentaenoic acid causes very little or no increase in secretion or synthesis as compared to a fatty-acid-free medium. the effects could already be observed aft ... | 1986 | 3021226 |

the adenosine triphosphate-pyrophosphate isotopic exchange reaction: a tool for determination of tryptophan. | quantitative determination of tryptophan at the picomole level is described, using the atp-[32p]ppi isotopic exchange reaction catalyzed by tryptophanyl-trna synthetase. sensitivity limits of 500 fmol were obtained. the presence of other amino acids at a 1000-fold excess over tryptophan did not interfere significantly with the quantitative determination of tryptophan. the specificity of the reaction was checked using five tryptophan analogs. these analogs did not prevent the determination of try ... | 2010 | 3014918 |
regulation of lateral flagella gene transcription in vibrio parahaemolyticus. | two distinctly different organelles of locomotion are produced by vibrio parahaemolyticus. the polar flagellum is responsible for motility in a liquid environment (swimming), and the lateral flagella enable the bacteria to move over surfaces (swarming). synthesis of lateral flagella occurs when v. parahaemolyticus is grown on agar media but not when it is grown in liquid media. we used lux (luminescence gene) fusions to conveniently and sensitively analyze the factors which influence transcripti ... | 1986 | 3013835 |
transposable resistance to trimethoprim and 0/129 in vibrio cholerae. | vibrio cholerae biotype el tor strain bm2508, resistant to trimethoprim, 0/129, streptomycin and spectinomycin was isolated from the faeces of a child with severe diarrhoea. resistance to trimethoprim and 0/129 was due to a dihydrofolate reductase type i and resistance to streptomycin-spectinomycin to a 3'',9-aminoglycoside-aminocyclitol adenylyltransferase. the resistance genes were not transferable to escherichia coli and, as inferred from ultracentrifugation in cesium chloride-ethidium bromid ... | 1986 | 3013828 |
a novel type of human papillomavirus associated with genital neoplasias. | the role of human papillomaviruses (hpvs) in the development of genital neoplasias has been well documented. the genomes of two hpv types, hpv16 and hpv18, have been found to be associated with about 70% of invasive carcinomas of the uterine cervix. as, under non-stringent hybridization conditions, hpv dna sequences have been detected in about 90% of cervical carcinomas, it seems likely that additional hpv types are associated with these tumours. here we report the molecular cloning and characte ... | 1986 | 3012352 |
cloning and expression of the exfoliative toxin b gene from staphylococcus aureus. | exfoliative toxin type b is produced by bacteriophage group ii strains of staphylococcus aureus and is a causative agent of staphylococcal scalded-skin syndrome. in addition to exfoliative toxin b, most isolates also produce a bacteriocin and are immune to the action of the bacteriocin. these phenotypes, as well as resistance to cadmium, were lost after elimination of a 37.5-kilobase plasmid, prw001, from s. aureus ut0007. transduction and transformation showed that prw001 carries the structural ... | 1986 | 3009410 |
densities and sizes of the main masticatory muscles in computed tomography compared with clinical findings related to temporomandibular joint (tmj) dysfunction. | computed tomography (ct) has a good resolution capacity and is an excellent method for measuring tissue densities. the aim here was to compare the densities and sizes of the main masticatory muscles, the masseter, medial pterygoid and lateral pterygoid muscles, as obtained with ct, with clinical findings in patients with tmj dysfunction (25) and controls (29). the densities of the masseter muscles and the medial pterygoid muscles showed no statistical difference between the patients and controls ... | 2010 | 3008236 |
effect of the hyp mutation and diet-induced hyperparathyroidism on renal parathyroid hormone- and forskolin-stimulated adenosine 3',5'-monophosphate production and brush border membrane phosphate transport. | the present study was undertaken to investigate the effect of the hyp mutation and diet-induced hyperparathyroidism on renal responsiveness to pth and forskolin and to determine whether the renal brush border membrane phosphate transport defect is expressed in the vitamin d- and calcium-deficient hyp mouse. our results indicate that pth is a potent activator of camp synthesis in renal slices obtained from vitamin d-replete normal mice and hyp littermates. however, in the mutants, the amount of c ... | 1986 | 3004890 |
nucleotide sequence and in vivo expression of the ilvy and ilvc genes in escherichia coli k12. transcription from divergent overlapping promoters. | the ilvc gene of escherichia coli k12 encodes acetohydroxy acid isomeroreductase, the second enzyme in the parallel isoleucine-valine biosynthetic pathway. previous data have shown that transcription of the ilvc gene is induced by the acetohydroxy acid isomeroreductase substrates, acetohydroxybutyrate or acetolactate, and that this substrate induction of ilvc expression is mediated by a positive activator encoded by the ilvy gene. we report here the isolation and complete nucleotide sequence of ... | 1986 | 3003115 |
malignant mixed mullerian tumor arising in extragenital endometriosis: report of a case and review of the literature. | a primary malignant mixed mullerian tumor (mmmt) was found in the wall of the rectum of a 67-year-old female. the uterus, fallopian tubes, and ovaries had been previously excised for benign disease. the tumor was associated with foci of benign endometriosis. a literature review of extragenital mmmts indicates that these are extremely rare tumors. this case supports the theory that endometriosis may serve as a progenitor to extraendometrial malignancy. | 2010 | 3002920 |
serum angiotensin-converting enzyme levels in sarcoid arthritis. | the serum angiotensin-converting enzyme (sace) level is elevated in 75% of patients with sarcoidosis and often is associated with disease activity. in an attempt to correlate the sace level with sarcoid arthritis, we did a retrospective chart review of 116 patients with sarcoidosis. of the 24 patients who complained of arthritis, five were excluded from the study because they were receiving corticosteroids, sace levels were not determined, or another cause for their arthritis was found. the mean ... | 2010 | 3002290 |
purification of a metalloproteinase inhibitor from human rheumatoid synovial fluid. | a metalloproteinase inhibitor present in human rheumatoid synovial fluid was purified by a combination of heparin-sepharose chromatography, concanavalin a-sepharose chromatography, ion-exchange chromatography and gel filtration. the mr of the purified inhibitor was 28000 by sds/polyacrylamide-gel electrophoresis and 30000 by gel filtration. the inhibitor blocked the activity of the metalloproteinases collagenase, gelatinase and proteoglycanase, but not thermolysin or bacterial collagenase. the s ... | 1985 | 3000352 |
effect of pyrimidinone treatment on lethal and immunosuppressive murine cytomegalovirus infection. | the 2-amino-5-halo-pyrimidinones, which are potent interferon inducers and antiviral agents, were found to be protective against lethal cytomegalovirus (cmv) challenge in weanling or neonatal mice when administered before virus challenge. this protection was dependent upon the dosage of pyrimidinone administered. weanling mice infected with a sublethal challenge of cmv exhibited moderate to severe immunosuppression as measured by reduced splenic cell blastogenic responses in vitro to the mitogen ... | 1985 | 3000290 |
