Trans-dehydrocrotonin has antiulcerogenic and antitumor activities. A complex of beta-cyclodextrin with dehydrocrotonin was developed to improve the delivery of dehydrocrotonin. Complex in solid state was evaluated using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). X-ray diffraction and scanning elec...

Imidazoles and their derivatives are compounds with chemotherapeutic applications. In this study, we investigated the chemical functionalization of carboxylated multiwalled carbon nanotubes (MWNT-COOH) by 1,2-phenylendiamine. Multiwalled nanotube (MWNT)-benzimidazole was obtained by an MWNT-amide reaction with POCl(3) after 72 hours, which was confirmed by Fourier transform infrared, scanning e...

Two new materials for adsorption of metal ions from aqueous media have been developed. The organic functional groups amine (–NH2) and sulfonate (–SO3H) were successfully attached to a commercially available fine-grained activated carbon (AC) via electrophilic aromatic substitutions. The surface properties of the materials were investigated using FTIR spectroscopy, XPS, BET surface area analysis...

20 new poly(ester-imide)s and poly(imide-urethane)s structures were synthesized using low temperature solution condensation polymerization. These compounds were optically active, capable of emitting circularly polarized light. The results indicated that the efficiency of the compounds much higher under this synthesis method. Cost effectiveness and short process were other advantages of this syn...

PURPOSE The implementation and evaluation of a gravimetric i.v. workflow software system in an oncology ambulatory care pharmacy are described. SUMMARY To estimate the risk involved in the sterile i.v. compounding process, a failure modes and effects analysis (FMEA) in the oncology ambulatory care pharmacy was performed. When a volumetric-based process was used to reconstitute vials, the actu...
