| properties of a mutant lactose carrier of escherichia coli with a cys148----ser148 substitution. | the cysteine residue at position 148 in the lactose carrier protein of escherichia coli has been replaced by serine using oligonucleotide-directed, site-specific mutagenesis of the lac y gene. the mutant carrier is incorporated into the cytoplasmic membrane to the same extent as the wild-type carrier, confers a lactose-positive phenotype on cells, and actively transports lactose and other galactosides. however, the maximum rate of transport for several substrates is reduced by a factor of 6-10 w ... | 1985 | 3922794 |
| idiopathic haemochromatosis and eye symptoms. a case report. | a 61-year-old man with idiopathic haemochromatosis and eye symptoms is described. the examination showed microaneurysms scattered over the bulbar conjunctiva, and some discrete pigmentations in the superficial tissue in the perilimbal area. each cornea revealed a light brown, ellipsoid opacity with the longest diameter horizontally, seemingly being located in the corneal epithelium and/or the anterior part of the stroma. a corneal biopsy was examined by light and electron microscopy. two differe ... | 1985 | 3923775 |
| cytogenetic study in six spanish patients with burkitt's lymphoma. | a cytogenetic study carried out on affected tissues of six children with burkitt's lymphoma revealed five cases with a typical translocation (8q-; 14q+) and one with a variant t(2p-; 8q+). additional cytogenetic variations were present in three cases. one had two acrocentric marker chromosomes comprised of material from chromosome #1 (1q21----q44) translocated to the y gonosome. the other two cases had a cytogenetic alteration of chromosome #12. cytogenetic studies carried out systematically in ... | 1985 | 3967210 |
| an enzymatic differential assay for urinary diamines, spermidine, and spermine. | subsequent to the hydrolysis of urinary conjugated amines by heating with hydrochloric acid, free amines were isolated by cation-exchange chromatography. spd and spm in an aliquot of amine extract were first oxidized by pao from penicillium chrysogenum, producing put and hydrogen peroxide. dias, which consist of the initially present dias plus put produced by pao, were subsequently oxidized by puo from micrococcus rubens, producing hydrogen peroxide. in an another aliquot of the amine extract di ... | 1985 | 3980559 |

| adrenergic receptors: possible mechanism of inverse regulation of alpha- and beta-receptors. | many physiologic and pathologic conditions, including bronchial asthma, are associated with inverse changes in alpha- and beta-receptor-mediated responses in various tissues. the direction of the change elicited by a given stimulus is tissue specific, as exemplified by the actions of thyroid hormones: in the rat heart, hypothyroidism reduces beta- and increases alpha-receptor responses, whereas in the rat liver it has the opposite effects. a similar increase in beta- and decrease in alpha-recept ... | 1985 | 2991359 |
| potentiation of cholinergic tone by pyridostigmine bromide re-instates and potentiates the growth hormone responsiveness to intermittent administration of growth hormone-releasing factor in man. | it is known that in normal subjects repeated administration of the growth hormone-releasing factor (grf) induces a state of partial refractoriness of the somatotropes to grf. studies were conducted to verify whether the cholinergic system plays a role in the mechanism(s) underlying the reduced gh responsiveness to the neuropeptide. in five healthy men, the gh response to three consecutive injections of grf (50 micrograms iv), administered at 2 h intervals, was considerably blunted after the seco ... | 1986 | 3020850 |
| immunogenic activity of gonococcal protein i in mice with three different lipoidal adjuvants delivered in liposomes and in complexes. | for several reasons the major outer membrane protein from neisseria gonorrhoeae (gonococcal protein [pi]) is an attractive component for a gonococcal vaccine. this paper describes the influence of two different physical forms of pi on its immunogenic activity. to this end pi was delivered in liposomes and in protein-detergent complexes. in both forms pi was present in a multimeric form. the liposomes were composed of phosphatidylcholine and cholesterol. the effect of dicetylphosphate as a negati ... | 1986 | 3095239 |
| in-vitro release of [14c]glutamate from dentate gyrus is modulated by gaba. | the effect of gaba (10(-3) and 10(-4) m) on the release of preloaded [14c]glutamate from slices of rat dentate gyrus, in response to k+ stimulation, was studied in ca2+-free and normal krebs solutions. release in ca2+-free solution was significantly enhanced, but there was no change in release in normal krebs solution. these results imply that ca2+-dependent (presumably neuronal) release of glutamate from the dentate gyrus is depressed by gaba, while non-neuronal ca2+-independent release is enha ... | 1986 | 2872320 |

| a novel glycosphingolipid that may participate in embryo inversion in volvox carteri. | mouse monoclonal antibody 4-i-244 detects a developmentally regulated antigen in embryos of volvox carteri and inhibits specifically the morphogenetic process of inversion (the process by which the embryo turns inside out). antigen 4-i-244 was chemically characterized as a complex phytosphingolipid containing the neutral sugars xylose, galactose, and glucose as well as inositol and phosphate. | 1986 | 3524860 |
| demonstration of sensory innervation of rat tongue with anterogradely transported horseradish peroxidase. | wheat germ agglutinin-horseradish peroxidase injected into the petrosal ganglion in rats was transported to the posterior tongue in the glossopharyngeal nerve. labelled fibers innervated the ipsilateral foliate papilla only, but both ipsi-and contralateral sides of the single circumvallate papilla. somatosensory fibers in the posterior tongue also were labelled. label crossed transcellularly from the afferent fibers into taste bud cells. use of this method provides more detailed knowledge of sen ... | 1986 | 3697712 |
| cohabitation, convergence, and environmental covariances. | temporal variation in traits has long been a central theme in epidemiology. however, human geneticists have largely avoided this topic. recently, several authors have shown how temporal variation in relative-to-relative covariances can be accommodated within the framework of variance components analysis. the present paper attempts to clarify the mathematics implicit in their approach. a stochastic mechanism is discussed that causes covariances to converge or diverge exponentially fast as relativ ... | 1986 | 3728567 |
| significance of the dog as 'second animal species' in toxicity testing for establishing the lowest 'no-toxic-effect level'. | the toxicity data of 66 compounds adequately tested in the rat (as 'prime animal species') and in the dog (as 'second animal species') were studied to find out for how many of these compounds the study in dogs led to a lower 'no-toxic-effect level' (ntel) than that found in the rat. from a quantitative point of view such information would contribute to a better insight into the desirability of toxicity studies in dogs, because acceptable daily intakes and permissible exposure levels in man are g ... | 1986 | 3760453 |

| polyunsaturated fatty acids augment free radical generation in tumor cells in vitro. | polyunsaturated fatty acids (pufas) have been shown to inhibit both normal and tumor cell growth in vitro. as pufas are known to induce a respiratory burst and free radical generation in polymorphonuclear leukocytes and since free radicals are toxic to cells, we investigated the effect of pufas on a measure of free radical generation (nitroblue tetrazolium reduction) in normal human fibroblasts and breast cancer cells in vitro. results suggested that linoleate (la), gamma-linolenate (gla), arach ... | 1987 | 3593336 |
| comparative evaluation of the immediate and sustained antibacterial action of two regimens, based on triclosan- and chlorhexidine-containing handwash preparations, on volunteers. | the degerming effect of a 3 min handwash with 2% triclosan, or 4% chlorhexidine, in detergent and enhanced efficacy of either antiseptic in isopropyl alcohol, was evaluated in volunteers. handwashing with either antiseptic preparation reduced the normal flora by a factor of 10; alcohol rubbing by approximately a factor of 1000. both regimens eliminated micrococcus roseus, artificially inoculated before every procedure. the sustained action of the same detergent preparations was further studied i ... | 1987 | 3595750 |
| the effect of heat upon the interaction between aminoglycosides and semi-synthetic penicillins in human serum: a consideration for hiv infectious serum. | we conducted 2 experiments to study the effect of heat on the interaction between aminoglycosides and semi-synthetic penicillins in human serum. in one experiment, human serum spiked with either gentamicin or tobramycin at a concentration of 4.7 mg/l plus carbenicillin, ticarcillin, piperacillin, mezlocillin, or azlocillin at concentrations of either 50 mg/l or 150 mg/l was subjected to a 30-min, 56 degrees c waterbath incubation. in the second experiment, randomly selected sera from patients re ... | 1987 | 3649918 |
| a rapid enzymatic assay for total blood polyamines. | we have designed a rapid, reliable enzymatic assay for total blood polyamines, as based on the combination of substrate specificity of polyamine oxidase (pao) from aspergillus terreus and putrescine oxidase (puo) from micrococcus rubens. quinone dye, derived from hydrogen peroxide generated in the oxidation reaction, is measured spectrophotometrically at 555 nm, and total amounts of putrescine (put), cadaverine (cad), spermidine (spd), and spermine (spm) can be readily determined. the minimum de ... | 1987 | 3652436 |
| the possible pitfalls of the measurement of intracellular calcium concentration of lymphocytes with the fluorescent indicator quin2. | the measurement of intracellular calcium concentration of small cells became feasible and relatively easily accomplishable following the development of the fluorescent calcium chelating dye, quin2, by r. y. tsien and his co-workers. the present paper gives an experimental survey of the major possible pitfalls of the method such as: 1) the improper choosing of the concentration of quin2/am, 2) the misinterpretation of the calibration procedure, 3) the accidental heavy metal traces in the medium, ... | 1987 | 3500116 |
| morphological evidence of innervation of taste buds of rat fungiform papillae after acute x-ray irradiation. | an acute dose of 2000 roentgens (r) of x-ray was delivered to the head and neck area of sprague-dawley rats. groups of rats were sacrificed at 0, 3, 7, 14, 21 and 30 days after x-ray irradiation. both general nerve staining and localization of cholinergic nerves by special staining of fungiform papillae were performed. no apparent change in number and distribution of nerve fibres were observed light microscopically within the fungiform papillae containing normal, degenerating and regenerating ta ... | 1987 | 3270572 |
| genetic factors in toxicology: implications for toxicological screening. | methods of assessing the toxicity of xenobiotics have improved substantially during the last decade. however, as compounds become generally safer, the problem of individual variation in response assumes increasing relative importance. environmental factors such as age, health and nutritional status, and interactions with other xenobiotics account for some of this variation, but genetic differences between individuals and races have important implications. in a few cases, mendelian loci which con ... | 1987 | 3311639 |
