    Notes: Summary Propranolol, a beta-adrenoceptor blocking drug, was administered to 6 healthy pregnant volunteers between 32 and 36 weeks gestation and when at least 6 weeks postparum. On both occasions, subjects were given propranolol 120 mg orally or 10 mg intravenously in randomised order with a minimum washout period of 1 week. Propranolol was assayed in plasma by gas-liquid chromatography with electron-capture detection and the pharmacokinetic parameters were investigated. There were no significant alterations in elimination half-life, clearance or apparent volume of distribution per kilogram antenatally compared with postnatally: bioavailability was also unchanged. It is concluded that the disposition of propranolol is not altered during pregnancy.

    Intrapatient variation in tobramycin kinetics in low birth weight infants during first postnatal week (1984)
    Springer

    ISSN: 1432-1041
    Keywords: tobramycin ; newborn infants ; intrapatient variations ; pharmacokinetics

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Nineteen newborn infants receiving tobramycin, 2.5 mg/kg every 12 h were studied on two occasions at steady-state during the first week of postnatal age. The two studies were separated by two to four days. Total body clearance of tobramycin averaged 1.15 and 1.14 ml/min/kg (p〉0.05), apparent volume of distribution averaged 0.82 and 0.68 l/kg (p〉0.05), and elimination half-life averaged 8.6 and 7.1 h (p〉0.05), during the first and second study, respectively. When the data were further analyzed based on the birth weight, tobramycin kinetics changed during the second study compared to the first study in very low birth weight infants. In eight infants ⩽1.5 kg birth weight, although total clearance of tobramycin was similar, the average apparent volume of distribution decreased from 1.04 l/kg during the first study to 0.73 l/kg during the second study (p〈0.05) and elimination half-life from 11.1 h during the first study to 8.7 h during the second study (p〈0.05). These data indicate that these infants may require a change in dosing interval with continued tobramycin therapy during the first week of postnatal age. Intrapatient variation in tobramycin kinetics should be considered, in addition to the interpatient variation reported previously, when monitoring the serum concentration to individualize tobramycin therapy in newborn infants ⩽1.5 kg birth weight.

    Acetaminophen accumulation in pediatric patients after repeated therapeutic doses (1984)
    Springer
    European journal of clinical pharmacology 27 (1984), S. 57-59

    ISSN: 1432-1041
    Keywords: acetaminophen ; pediatric patients ; fever therapy ; accumulation ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Acetaminophen serum concentrations were studied in 21 infants and children with fever. The maximum serum concentrations ranged from 9.96 to 19.6 µg/ml after a single dose of 12–14 mg/kg and 13.9 to 40.1 µg/ml after a single dose of 22–27 mg/kg. Ten patients were restudied at steadystate after repeat doses had been given every 4 or 8 h for 1 to 3 days. Total area under the acetaminophen serum concentration-time curve normalized for dose averaged 0.181 (ml/min/kg)−1 after the first dose and 0.202 (ml/min/kg)−1 at steady-state (p〈0.05). Five patients showed a 13 to 44% increase in the AUC; one had a 10% decrease in the AUC; and four had less than 6% change in the AUC. There was no evidence of hepatotoxicity. These data suggest that acetaminophen may accumulate after repeated therapeutic doses in children with fever.

    Pharmacokinetic and pharmacodynamic study of the combination of furosemide retard and triamterene (1984)

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacodynamics and pharmacokinetics of the combination of furosemide retard (30 mg)/triamterene (50 mg) were compared with furosemide (30 mg) in 18 healthy male volunteers aged 39.3±6.3 years. After the administration of furosemide the onset of its effect was very rapid, reaching a maximum between 1.5 to 3 h, and followed by rebound after 9 to 10.5 h. In contrast the combination furosemide retard/triamterene showed a protracted course with a duration of effect up to 12 h. The general effect over 12 h of the two preparations was equivalent with respect to the excretion of urine, sodium, chloride and calcium, but the combination caused significantly less excretion of potassium (p≤0.05) than furosemide. After a lag-phase of 33.9±5.4 min the maximum plasma concentration of furosemide was reached after 3.47±0.66 h, and the elimination half-life was approximately 2 h. After a lag-phase of 33.0±17.8 min the maximum plasma concentration of the main metabolite of triamterene, the OH-TA sulphuric acid ester, was reached after 1.7±0.59 h, and its elimination half-life amounted to 1.25±0.37 h. Because of the sustained release of furosemide from the retard-formulation, its principal pharmacokinetic parameters were better adapted to those of triamterene. The consequences were not only a protracted effect but also an improved electrolyte profile, especially with regard to reduced loss of potassium. In the case of renal insufficiency, however, the potassium level in serum might be increased to an undesirable extent.

    Genetic definition and sequence analysis of Arabidopsis centromeres (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-01-05
    Description: High-precision genetic mapping was used to define the regions that contain centromere functions on each natural chromosome in Arabidopsis thaliana. These regions exhibited dramatic recombinational repression and contained complex DNA surrounding large arrays of 180-base pair repeats. Unexpectedly, the DNA within the centromeres was not merely structural but also encoded several expressed genes. The regions flanking the centromeres were densely populated by repetitive elements yet experienced normal levels of recombination. The genetically defined centromeres were well conserved among Arabidopsis ecotypes but displayed limited sequence homology between different chromosomes, excluding repetitive DNA. This investigation provides a platform for dissecting the role of individual sequences in centromeres in higher eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Copenhaver, G P -- Nickel, K -- Kuromori, T -- Benito, M I -- Kaul, S -- Lin, X -- Bevan, M -- Murphy, G -- Harris, B -- Parnell, L D -- McCombie, W R -- Martienssen, R A -- Marra, M -- Preuss, D -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2468-74.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Chicago, Department of Molecular Genetics and Cell Biology, 1103 East 57 Street, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617454" target="_blank"〉PubMed〈/a〉

    Role of the mouse ank gene in control of tissue calcification and arthritis (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-07-15
    Description: Mutation at the mouse progressive ankylosis (ank) locus causes a generalized, progressive form of arthritis accompanied by mineral deposition, formation of bony outgrowths, and joint destruction. Here, we show that the ank locus encodes a multipass transmembrane protein (ANK) that is expressed in joints and other tissues and controls pyrophosphate levels in cultured cells. A highly conserved gene is present in humans and other vertebrates. These results identify ANK-mediated control of pyrophosphate levels as a possible mechanism regulating tissue calcification and susceptibility to arthritis in higher animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ho, A M -- Johnson, M D -- Kingsley, D M -- 5T32GM07365/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Jul 14;289(5477):265-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology and Howard Hughes Medical Institute, Beckman Center B300, Stanford University School of Medicine, Stanford, CA 94305-5327, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10894769" target="_blank"〉PubMed〈/a〉

    Requirement of the inositol trisphosphate receptor for activation of store-operated Ca2+ channels (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-03-04
    Description: The coupling mechanism between endoplasmic reticulum (ER) calcium ion (Ca2+) stores and plasma membrane (PM) store-operated channels (SOCs) is crucial to Ca2+ signaling but has eluded detection. SOCs may be functionally related to the TRP family of receptor-operated channels. Direct comparison of endogenous SOCs with stably expressed TRP3 channels in human embryonic kidney (HEK293) cells revealed that TRP3 channels differ in being store independent. However, condensed cortical F-actin prevented activation of both SOC and TRP3 channels, which suggests that ER-PM interactions underlie coupling of both channels. A cell-permeant inhibitor of inositol trisphosphate receptor (InsP3R) function, 2-aminoethoxydiphenyl borate, prevented both receptor-induced TRP3 activation and store-induced SOC activation. It is concluded that InsP3Rs mediate both SOC and TRP channel opening and that the InsP3R is essential for maintaining coupling between store emptying and physiological activation of SOCs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ma, H T -- Patterson, R L -- van Rossum, D B -- Birnbaumer, L -- Mikoshiba, K -- Gill, D L -- AR07592/AR/NIAMS NIH HHS/ -- HL55426/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2000 Mar 3;287(5458):1647-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, University of Maryland, School of Medicine, Baltimore, MD 21201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10698739" target="_blank"〉PubMed〈/a〉

    Fas preassociation required for apoptosis signaling and dominant inhibition by pathogenic mutations (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-07-06
    Description: Heterozygous mutations encoding abnormal forms of the death receptor Fas dominantly interfere with Fas-induced lymphocyte apoptosis in human autoimmune lymphoproliferative syndrome. This effect, rather than depending on ligand-induced receptor oligomerization, was found to stem from ligand- independent interaction of wild-type and mutant Fas receptors through a specific region in the extracellular domain. Preassociated Fas complexes were found in living cells by means of fluorescence resonance energy transfer between variants of green fluorescent protein. These results show that formation of preassociated receptor complexes is necessary for Fas signaling and dominant interference in human disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siegel, R M -- Frederiksen, J K -- Zacharias, D A -- Chan, F K -- Johnson, M -- Lynch, D -- Tsien, R Y -- Lenardo, M J -- NS27177/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Jun 30;288(5475):2354-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10875918" target="_blank"〉PubMed〈/a〉
