13. Characterization of β-lapachone and methylated β-cyclodextrin solid-state systems
The purpose of this research was to explore the utility of β cyclodextrin (βCD) and β cyclodextrin derivatives (hydroxypropyl-β-cyclodextrin [HPβCD], sulfobutylether-β-CD [SB\CD], and a randomly methylated-β-CD [RMβCD]) to form inclusion complexes with the antitumoral drug, β-lapachone (βLAP), in order to overcome the problem of its poor water solu

14. Physicochemical characterization, in vitro dissolution behavior, and pharmacodynamic studies of rofecoxib-cyclodextrin inclusion compounds. Preparation and properties of rofecoxib hydroxypropyl β-cyclodextrin inclusion complex: A technical note
An inclusion complex of rofecoxib and HPβ-CD was prepared successfully by the spray-drying method in a molar ratio of 1∶1. The inclusion complex was found to have improved in vitro drug release compared with the pure drug. The solubility profile of complexes of rofecoxib prepared using HPβ-CD as the complexing agent in a molar ratio of 1∶1 by the spray

15. Preformulation Study of the Inclusion Complex Irbesartan-β-Cyclodextrin
The aim of the present work was to improve the solubility and dissolution profile of Irbesartan (IRB), a poorly water-soluble drug by formation of inclusion complex with β-cyclodextrin (βCD). Phase solubility studies revealed increase in solubility of the drug upon cyclodextrin addition, showing AL—type of graph with slope less than one indicating format

16. Diclofenac-β-cyclodextrin binary systems: Physicochemical characterization and in vitro dissolution and diffusion studies
The aim of this work was to study the influence of β-cyclodextrin (β-CD) on the biopharmaceutic properties of diclofenac (DCF). To this purpose the physicochemical characterization of diclofenac-β-cyclodextrin binary systems was performed both in solution and solid state. Solid phase characterization was performed using differential scanning calorimetry (

17. Insulin receptors in isolated human adipocytes. Characterization by photoaffinity labeling and evidence for internalization and cellular processing.
We photolabeled and characterized insulin receptors in isolated adipocytes from normal human subjects and then studied the cellular fate of the labeled insulin-receptor complexes at physiologic temperatures. The biologically active photosensitive insulin derivative, B2(2-nitro-4-azidophenylacetyl)des-PheB1-insulin (NAPA-DP-insulin) was used to photoaffinity

18. Characterization of a neutralizing monoclonal antibody directed at variable domain I of the major outer membrane protein of Chlamydia trachomatis C-complex serovars.
A monoclonal antibody (MAb), C10, that neutralized in vitro the infectivity of serovars C, I, J, and L3 (members of the C and C-related complexes) of Chlamydia trachomatis was identified. Of the 15 major serovars and the mouse pneumonitis strain of C. trachomatis, Chlamydia psittaci, and Chlamydia pneumoniae, which were used as nontreated and heat-treated (5

19. Purification and partial characterization of the major outer membrane protein of Chlamydia trachomatis.
Elementary bodies (EB) of Chlamydia trachomatis serotypes C, E, and L2 were extrinsically radioiodinated, and whole-cell lysates of these serotypes were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Autoradiography of the polypeptide profiles identified a major surface protein with an apparent subunit molecular weight of 3
