STI571 (imatinib mesylate; Gleevec®) is an inhibitor that targets the tyrosine kinase activity of Bcr-Abl present in chronic myelogenous leukemia (CML) cells. Some preclinical studies have demonstrated that the combination of STI571 with chemotherapeutic drugs results in enhanced toxicity in Bcr-Abl-positive leukemias. We investigated the potential benefit of using STI571 to down-regulate Bcr-Abl...
Research was conducted to recognize interrelations between morphology and mechanical properties of starch. Microscopic examination, determination of particle size distribution, as well as direct shear and uniaxial compression testing were performed on five types of starch extracted out of: potato, wheat, corn, tapioca and amaranth. Regarding geometrical features (morphology) of granules, three distinct...
Small Angle X-ray Scattering (SAXS) has been applied to the study of starch structure in wheat flour. The quality of the range changes of starch microstructure after milling was analysed and a certain relationship of SAXS scattering magnitudes with alveographic study was shown.
Recently we observed that the transcription factors Sp1 and Sp3 bind to the CTCCTCCTC sequence located between positions -194 and -172 of the αv promoter region and are directly involved in the regulation of transcriptional activity of the αv gene in human umbilical vascular endothelial cells (HUVECs) (Czyz & Cierniewski, 1999, Eur. J. Biochem. 265, 638). In this report we provide evidence that...
