    Notes: Background : Patients report that the prophylactic consumption of a proton pump inhibitor minimizes gastrointestinal symptoms expected to be provoked by late-night food and alcohol consumption. The efficacy of this practice has not been studied formally.Aim : To perform a randomized, double-blind, placebo-controlled trial of a single dose of lansoprazole (30 mg) taken prior to a large meal and alcohol consumption.Methods : Study subjects were recruited randomly from local primary care and hospital physicians. Each participant (n = 56; 37 male, 19 female; mean age, 38 years) completed questionnaires before and after the meal. Approximately 90 min prior to the provocative meal, participants were witnessed taking either placebo or 30 mg lansoprazole. Bar tokens were dispensed to permit the accurate quantification of alcohol consumption (mean, 15 units).Results : Forty per cent of subjects reported significant reflux symptoms. For the entire group, there was no significant difference between lansoprazole and placebo. Post-prandial reflux was more frequent in those consuming 〉 15 units of alcohol (13/26, 50%) compared with those consuming 〈 15 units (7/30, 24%; P 〈 0.05). In the group who consumed 〉 15 units of alcohol, lansoprazole was associated with a lower rate of heartburn (5/15, 33%) compared with placebo (8/11, 73%; P 〈 0.05).Conclusion : A single dose of a proton pump inhibitor prior to indulgence was only associated with reduced heartburn in those consuming 〉 15 units of alcohol.

    Undercut reproducibility of functional impression materials (tissue conditioners) (1978)

    Notes: Impressions of, a laboratory model of an edentulous ridge were made with three commercial tissue conditioners (FITT, Hydro-Cast and Coe-Comfort). Combinations of undercut dimensions and tray relief were tested by using three different sized trays with each tissue conditioner. Greater tray relief increased the accuracy of all materials tested; increasing ageing time from 7 to 24 h resulted in little change of accuracy of the stone models poured from the impressions taken.

    Uptake and release of phosphorus by phytoplankton in the Chesapeake Bay estuary, USA (1975)
    Springer
    Marine biology 33 (1975), S. 21-32 
    Details
    ISSN: 1432-1793

    Topics: Biology
    Notes: Abstract The phytoplankton uptake and release rates for inorganic phosphate, dissolved organic phosphate and polyphosphate were estimated during 5 cruises on the Chesapeake Bay over a 9-month period. Phosphorus in all pools turned over in several minutes to 100 h, and each soluble pool appeared to contain fractions which were metabolically useful to the phytoplankton. Maximal uptake rates (V m ) for orthophosphate ranged from 0.02 to 2.95 μg-at P (1.h)-1 with half saturation constants (K s ) between 0.09 and 1.72 μg-at P l-1. At low soluble reactive phosphorus concentrations, the uptake rate of trace 32P orthophosphate was initially rapid, but declined after 15 to 60 min incubation. The data suggest that the initial uptake phase was dominated by exchange of 32PO4 ≡ for 31PO4 ≡ in the membrane transport systems whereas the subsequent phase represented the net incorporation of orthophosphate into phytoplankton cells.

    Revised report on the algorithmic languageAlgol 60 (1962)
    Springer
    Numerische Mathematik 4 (1962), S. 420-453 
    Details
    ISSN: 0945-3245
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Summary The report gives a complete defining description of the international algorithmic languageAlgol 60. This is a language suitable for expressing a large class of numerical processes in a form sufficiently concise for direct automatic translation into the language of programmed automatic computers. The introduction contains an account of the preparatory work leading up to the final conference, where the language was defined. In addition the notions reference language, publication language, and hardware representations are explained. In the first chapter a survey of the basic constituents and features of the language is given, and the formal notation, by which the syntactic structure is defined, is explained. The second chapter lists all the basic symbols, and the syntactic units known as identifiers, numbers, and strings are defined. Further some important notions such as quantity and value are defined. The third chapter explains the rules for forming expressions and the meaning of these expressions. Three different types of expressions exist: arithmetic, Boolean (logical), and designational. The fourth chapter describes the operational units of the language, known as statements. The basic statements are: assignment statements (evaluation of a formula), go to statements (explicit break of the sequence of execution of statements), dummy statements, and procedure statements (call for execution of a closed process, defined by a procedure declaration). The formation of more complex structures, having statement character, is explained. These include: conditional statements, for statements, compound statements, and blocks. In the fifth chapter the units known as declarations, serving for defining permanent properties of the units entering into a process described in the language, are defined. The report ends with two detailed examples of the use of the language and an alphabetic index of definitions.

    Properties and regulation of ribulose diphosphate carboxylase from Thiobacillus novellus (1975)

    Notes: Abstract Ribulose-diphosphate carboxylase from Thiobacillus novellus has been purified to homogeneity as observed by polyacrylamide gel electrophoresis and U. V. light observation during sedimentation velocity analysis. The optimum pH for the enzyme with Tris-HCl buffers was about 8.2. Concentrations of this buffer in excess of 80 mM were inhibitory. The apparent K m RuDP was about 14.8 μM with a Hill value of 1.5, for HCO 3 - the apparent K m was about 11.7 mM with an n value of 1.18 and for Mg2+ about 0.61 mM. The enzyme was specific for this cation. Relatively high concentrations of either Hg2+ or pCMB were required before significant inhibition was observed. Activity declined slowly during a 4-hr incubation period in either 3.0 M or 8.0 M urea. Incubation for 12 hrs resulted in complete loss of activity which was not prevented by 10 mM Mg2+ and was not reversed by dialysis and subsequent addition of 10 mM cysteine. Polyacrylamide gel electrophoresis revealed a loss of the major band and the appearance of 2 new bands. SDS polyacrylamide gel electrophoresis gave an average M.W. of 73 500±2500 for the slower moving band and 12250 ±2500 for the faster moving. However, incubation in urea for up to 40 hrs revealed a decrease in the M.W. of the slower moving band to about 60000. The E a for the enzyme was calculated to be about 18.85 kcal mole-1, with the possibility of a “break” between 40 and 50°C. The Q 10 was 3.07 between 20 to 30°C whereas between 30 to 40°C it was 3.31. Only phosphorylated compounds caused significant inhibition of enzyme activity. They included ADP, FDP, F6P, G6P, PEP, 6PG, 2-PGA, R1P, R5P and Ru5P.
