| measuring gene expression with light. | light is produced by recombinant escherichia coli that contain lux genes cloned from the marine bacterium vibrio fischeri. the bioluminescence phenotype requires genes for regulatory and biochemical functions, the latter encoded by five lux genes contained in a single operon. these lux genes were disconnected from their native promoter and inserted into the transposon mini-mu. the resulting transposon, mini-mulux, could induce mutations by insertional inactivation of a target gene, and the lux d ... | 1985 | 2983423 |
| respiration-driven na+ pump and na+ circulation in vibrio parahaemolyticus. | sodium circulation in vibrio parahaemolyticus was investigated. we observed respiration-driven na+ extrusion from cells by using a na+ electrode. the na+ extrusion was insensitive to a proton conductor, carbonyl cyanide m-chlorophenylhydrazone, and sensitive to a respiratory inhibitor, cn-. these results support the idea of the existence of a respiratory na+ pump in v. parahaemolyticus. the respiration-driven na+ extrusion was observed only under alkaline conditions. | 1985 | 2985548 |
| respiratory syncytial virus fusion glycoprotein: nucleotide sequence of mrna, identification of cleavage activation site and amino acid sequence of n-terminus of f1 subunit. | the amino acid sequence of respiratory syncytial virus fusion protein (fo) was deduced from the sequence of a partial cdna clone of mrna and from the 5' mrna sequence obtained by primer extension and dideoxysequencing. the encoded protein of 574 amino acids is extremely hydrophobic and has a molecular weight of 63371 daltons. the site of proteolytic cleavage within this protein was accurately mapped by determining a partial amino acid sequence of the n-terminus of the larger subunit (f1) purifie ... | 1985 | 2987829 |
| conditioned taste aversion suppresses induction of delayed-type hypersensitivity immune reactions. | conditioned taste aversion was induced in mice by pairing saccharin drinking with an intraperitoneal injection of lithium chloride, a toxic but nonimmunosuppressive drug. conditioned mice showed not only suppressed saccharin drinking but also a 75% reduction in the induction of delayed-type hypersensitivity immune responses to low doses of sheep erythrocytes. this effect was observed with doses of lithium chloride which had no effect of their own on immune functions. in addition, a reduction in ... | 1985 | 2987987 |
| receptors for epidermal growth factor in the rat uterus. | uterine membranes contain high affinity [dissociation constant (kd) = 0.36 nm], saturable binding sites for [125i]iodo-epidermal growth factor (egf). the binding of [125i] iodo-egf is specific since it is abolished by excess unlabeled egf but not by excess unlabeled insulin, fibroblast growth factor, or multiplication-stimulating activity. incubation of [125i] iodo-egf with uterine membranes, followed by chemical cross-linking with disuccinimidyl suberate and detergent extraction reveals a major ... | 1985 | 2988913 |
| macrophage colony-stimulating factor (m-csf) enhances the capacity of murine macrophages to secrete oxygen reduction products. | the capacity of macrophage colony-stimulating factor (m-csf) to enhance respiratory burst activity in peritoneal macrophages was measured. macrophages incubated for 48 hr or more with concentrated l cell-conditioned medium as a source of m-csf released two to three times as much o2- in response to pma as did unexposed macrophages. stimulation was noted at concentrations of colony-stimulating activity from 0.1 to 2000 u/ml and was maximal at 10 to 100 u/ml. purified, endotoxin-free csf enhanced s ... | 2010 | 2991376 |
| opiate- and alpha 2-adrenoceptor-induced hyperpolarizations of locus ceruleus neurons in brain slices: reversal by cyclic adenosine 3':5'-monophosphate analogues. | the purpose of this study was to investigate the ionic and second messenger mechanisms underlying the hyperpolarizations induced by the selective alpha 2-adrenoceptor agonist clonidine and the opiate agonist morphine in the locus ceruleus. intracellular recordings were carried out in rat brain slices, and drugs at known concentrations were administered in the perfusate. the cyclic adenosine 3':5'-monophosphate (camp) analogues 8-bromo-camp and dibutyryl camp, while not altering basal activity, r ... | 1985 | 2993542 |
| a nonsteroid anti-inflammatory drug exacerbates coxsackie b3 murine myocarditis. | nonsteroid anti-inflammatory drugs are often used to treat myalgias and arthralgias in enteroviral infections, but their effects on acute viral myocarditis are unknown. the effect of the nonsteroidal anti-inflammatory drug, ibuprofen, on acute viral myocarditis was studied in 75 four week old male balb/c mice infected with 1.75 x 10(7) plaque-forming units of coxsackie virus b3 on day 0. ibuprofen was given intraperitoneally at a dose of 15 mg/kg body weight daily. the mice were assigned to four ... | 1985 | 2995470 |
| the biologic significance of the mixed lymphocyte kidney culture in humans. | the mixed lymphocyte kidney culture (mlkc) in humans has been studied in normal and abnormal clinical conditions. human renal cortical cells were extracted by collagenase treatment from the kidneys of "normal" heart-beating cadaver organ donors (n = 13), patients with end-stage renal disease (esrd) at pretransplant bilateral nephrectomy and splenectomy (n = 13), and from irreversibly rejected renal allografts at the time of graft nephrectomy (n = 5). proliferation of peripheral blood t lymphocyt ... | 1985 | 2996186 |

| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |

| pharmacological modification of pulmonary vascular injury: possible role of camp. | experiments were designed to test the hypothesis that drugs which increase adenosine 3',5'-cyclic monophosphate (camp) in the lung would prevent the pulmonary hypertension and the increase in vascular permeability caused by the infusion of the oxidant lipid peroxide, tert-butyl hydroperoxide (t-bu-ooh), in isolated rabbit lungs perfused with krebs-henseleit buffer. pretreatment with indomethacin or verapamil was also studied, since these drugs block the increase in pulmonary arterial pressure ca ... | 1987 | 3031002 |
| membrane phospholipids alter nutrient transport and drug toxicity in tumorigenic fibroblasts. | the phospholipid polar head group composition of lm cell plasma membranes was nutritionally altered by choline analogue supplementation. phosphatidylcholine (pc), normally 60% of total phospholipid, was depleted by 60 to 90% in membranes from cells cultured with n, n'-dimethylethanolamine (dme), n-monomethylethanolamine (me), and ethanolamine (e). enrichment of lm cell membranes with choline analogues, such as dme-, me-, and e-containing phospholipids, decreased the transport of [3h]thymidine, [ ... | 2011 | 3032553 |
| role of postnatal gonadal function in the determination of thyrotropin (tsh) releasing hormone-induced tsh response in adult male and female rats. | permanent effects of postnatal gonadal function on the hypothalamo-pituitary-thyroid axis were examined in male and female rats of the wistar-imamichi strain. animals were used at the age of about 10 weeks. neonatally castrated (nc) males showed a significantly higher plasma tsh response to trh (10 micrograms/kg bw, ip) than males castrated at 1, 2, 3, 4, or 6 weeks of age. the tsh response in intact males was similar to that seen in nc males. neonatal androgenization of nc males with 100 microg ... | 1987 | 3032567 |
| calmodulin in porcine malignant hyperpyrexia. | the anaesthetic complication malignant hyperpyrexia (mh) is due to an elevation of the myoplasmic ca2+ concentration. examination of calmodulin isolated from mh susceptible swine suggests that the disorder in calcium regulation in mh is not due to an abnormality in calmodulin. | 1987 | 3032704 |
| a novel mechanism for utilization of extracellular amp in vibrio parahaemolyticus. | vibrio parahaemolyticus could grow with amp, adp or atp as the sole source of carbon. in the presence of cl-, a membrane-bound cl(-)-dependent 5'-nucleotidase seemed to hydrolyze the nucleotides extracellularly, and then the cells took up the resulting adenosine. in the absence of cl-, although no significant dephosphorylation of the nucleotides occurred, the cells could still grow with amp, but not with adp or atp. moreover, in the presence of cl-, zn2+ inhibited the 5'-nucleotidase, and inhibi ... | 1987 | 3034248 |
| active lambda and kappa antibody gene rearrangement in abelson murine leukemia virus-transformed pre-b cell lines. | the two abelson murine leukemia virus (a-mulv)-transformed cell lines, bm18-4 and abc-1, undergo immunoglobulin l-chain gene recombination during passage in tissue culture. bm18-4 cells are capable of kappa gene recombination, whereas abc-1 cells are capable of both kappa and lambda gene recombination. the expression of h chains is apparently not necessary for continuing l chain gene recombination in either of these cells, although h-chain expression may have been involved in the initiation of l ... | 1987 | 3035056 |
