    A clinical and pharmacodynamic evaluation of sulpiride (1981)

    Notes: Abstract In a double-blind study the therapeutic efficacy of sulpiride was compared to that of haloperidol — an established neuroleptic agent. A total of 30 female patients with a diagnosis of chronic schizophrenia were initially stabilised on the dosage of haloperidol which produced optimum therapeutic response when given once or twice daily. The patients were then randomly allocated to receive either sulpiride or haloperidol over a period of 12 weeks. Plasma drug concentrations and prolactin levels were determined. Clinical effects were evaluated by Brief Psychiatric Rating Scale (BPRS), Wing Rating Scale, and Extrapyramidal Symptoms Rating Scale (EPS). A standardised side-effects checklist was used. Treatment with sulpiride was associated with a significant rise in plasma prolactin level, but paradoxically these patients had significantly reduced extrapyramidal symptoms. No significant correlation was found between plasma sulpiride concentration and prolactin level or any of the clinical variables. The study confirms the antipsychotic activity of sulpiride.

    Differences between vertical transfers and native students in four-year institutions (1977)
    Springer
    Research in higher education 7 (1977), S. 145-154 
    Details
    ISSN: 1573-188X
    Keywords: transfers ; financial aid ; individual characteristics ; college student ; achievement ; background variable

    Notes: Abstract Data from the National Longitudinal Study of the High School Class of 1972 were drawn to compare those who transfer from two-year colleges and those who enroll in four-year institutions immediately after high school. The comparisons were made on background variables, individual characteristics, and financial aid status. Results indicated that transfers came from lower SES families, and had lower academic ability, high school achievement, and educational aspiration than native students. Transfers were less likely than native students to receive scholarships, fellowships, or grants, and they showed lower achievement in the year after transfer. Implications of these findings are discussed.

    Notes: Abstract The major volatile components in the extract of the female sex pheromone gland ofAmorbia cuneana consisted of (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates. The identification was based on electroantennogram bioassay of gas Chromatographic effluent from sex pheromone gland extract, relative retention times on polar and nonpolar gas chromatographic columns, chemical degradation (ozonolysis, saponification), mass spectrometry, chemical synthetic methods, and field tests. Based on mass spectrometry and retention times by capillary gas chromatography, traces of (E)-10-tetradecen-1-ol acetate and 1-tetradecanol acetate were also present in the extract. Traps baited with a combination of synthetic (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates caught more males than did traps baited with females.

    Immobilization of enzymes on activated carbon: Selection and preparation of the carbon support (1979)

    Notes: Based upon its superior catalytic activity for H2O2 decomposition, a bituminous coal-based activated carbon was selected for investigations of pretreatment and enzyme immobilization methods. Pretreatments considered include acid washing, exposure to strong oxidizing agents, contact with concentrated peroxide solutions, nitration and amination, isothiocyanate derivatization, silanization, and stearic acid coating. Effects of these pretreatments on morphology and trace-metal content of the carbon pellets have been studied using scanning electron microscopy and dispersive analysis of x rays. Immobilization of glucoamylase by adsorption, glutaraldehyde crosslinking, and covalent attachment to carbon activated by water-soluble diimide or diazotization have been examined. These different enzyme-carbon catalysts have been characterized by their enzyme loading, enzyme activity, catalytic activity for H2O2 decomposition, or combinations of these measures of performance.

    Immobilization of enzymes in porous supports: Effects of support-enzyme solution contacting (1984)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Proteins have been immobilized in porous support particles held in a fixed-bed reactor through which protein solution is continuously circulated. Changing the recirculation flow rate alters the observed immobilization kinetics and the maximum enzyme loading which can be achieved for glucose oxidase and glucoamylase on carbodiimide-treated activated carbon and for glucoamylase immobilized on CNBr-Sepharose 4B. Direct microscopic examination of FITC-labelled protein in sectioned Sepharose particles and indirect activity-loading studies with activated carbon-enzyme conjugates all indicate that immobilized enzyme is increasingly localized near the outer surface of the support particles at larger recirculation flow rates. Restricted diffusion of enzymes may be implicated in this phenomenon. These contacting effects may be significant considerations in the scaleup of processes for protein impregnation in porous supports, since apparent activity and stability of the final preparation depend on internal protein distribution.

    Diffusional influences on the parametric sensitivity of immobilized enzyme catalystsNCL Communication No. 2141. (1978)

    Notes: Immobilization of an enzyme within an insoluble material permeable to substrate can change the apparent behavior of the enzyme. In particular, external mass transfer and intraparticle diffusion effects can significantly influence the dependence of observed reaction rate on operating parameters such as temperature and pH. This analysis shows that, under very general conditions, the influence of diffusion alone is to diminish the sensitivity of the observed rate to any parameter that is uniform throughout the catalyst particle. However, the optimal value of the parameter is not changed because of intrapellet diffusional effects.
