a computational study of the electronic structure and stability of complexes formed between zeolite y and boric acid was carried out at the hf and b3lyp levels using 6-31g* basis set. five structures located as local minimum in pes of complex (structures d, e, f, g, and h). the most stable structure is formed due to hydrogen bonding between two hydroxyl of boric acid and both oxygen of ...

Gliomas are the most common form of brain tumors, contributing to more than half of the incidence of brain tumors. They are derived from three basic types of glial cells: astrocytes, oligodendrocytes and ependymal cells. The most frequent are diffusely infiltrating astrocytomas, further classified into astroytomas (A), anaplastic astrocytomas (AA) and glioblastoma, equivalent to World Health Or...

vinblastine is an important anticancer agent known to diminish microtubule assembly. ab initio calculations are applied to examine the structural properties and different energies of vinblastine-tubulin complex in different dielectric constants and temperatures. the aims of this work are discovery the best optimized structure and thermodynamic properties of vinblastine-tubulin complex and compa...

introduction : in order to evaluate the role of thyroid autoimmunity in patients with goiter, this study was done 10 years after implementation of iodine supplementation program ( iodised salt). the serum levels of thyroid peroxidase antibodies (anti tpo) and thyroglobulin antibodies (anti tg) were studied in a group of patients with simple goiter and compared with normal controls. materials an...
