Design, Characterization, DNA Interaction and antimicrobial of novel copper(II) Schiff base amino acid complexes
Five novel copper(II) complexes derived from the condensation between 5-bromosalicyaldhyde (bs) and α-amino acids (L-alanine, L-phenylalanine, L-aspartic acid, L-histidine and L-arginine) were synthesized and characterized by their elemental analyses, thermogravemetric analysis, IR, electronic spectra and conductance and magnetic measurements. Moreover, the stoichiometry and the stability constants of the prepared complexes have been determined spectrophotometrically. The Results indicated that the Schiff ... Read more

Isolation and Characterization of Multipotent Stem Cells from The Olfactory Mucosa and Olfactory Bulb of The Adult Male Albino Rats
Olfactory stem cells (OSCs) are multipotent stem cells that can be isolated from the olfactory mucosa and olfactory bulb and have the capacity to proliferate when cultured on suitable media. Isolation of these cells helps to study their identity before being used as a cell therapy. THE AIM of this study is to isolate rat OSCs from olfactory mucosa and ... Read more

The therapeutic efficacy of olfactory stromal cells in rotenone induced Parkinsonism in adult male albino rats
_Background aims. _ Olfactory stem cells (OSCs) are found in the olfactory mucosa and olfactory bulb and have the capacity to proliferate and differentiate along multiple tissue lineages. Rotenone; widely used insecticide has a neurodegenerative effect on the dopaminergic cells of substantia nigra (SN) of midbrain producing Parkinsonism. The aim of this study is to isolate rat OSCs from olfactory ... Read more

Nano structure Iron (II) and Copper (II) Schiff base complexes of a NNO-tridentate ligand as new antibiotic agents: spectral, thermal behaviors and DNA binding ability
Complexes of Fe (II) and Cu (II) with a tridentate Schiff base, 2-((z)-(pyridine-2-ylimino) methyl) naphthalene1-ol derived from 2-hydroxy-1-napthaldehyde and 2-aminopyridine were synthesized. Both the ligand and its complexes were characterized on the basis of microanalysis, melting point, 1H and 13CNMR, molar conductivity, thermal analysis, IR and UV/Vis spectral studies. From analytical data, the stoichiometry of the complexes was found to ... Read more

α-Bi2O3 nanorods: synthesis, characterization and UV-photocatalytic activity
In this study, Monoclinic bismuth oxide nanorods (_α_-Bi2O3 NRs) were successfully synthesized by a simple one-step hydrothermal route using (water: ethanol) (1:1) as a mixed solvents at optimum conditions. The Bi2O3 nano-powder was characterized in detail by different techniques in terms of their structural, morphological, compositional, optical and photocatalytic properties. X-ray diffraction (XRD) analysis indicated that the as-synthesized Bi2O3 NRs ... Read more
