Synthesis, physicochemical studies, embryos toxicity and DNA interaction of some new Iron(II) Schiff base amino acid complexes
New Fe(II) Schiff base amino acid complexes derived from the condensation of o-hydroxynaphthaldehyde with l-alanine, l-phenylalanine, l-aspartic acid, l-histidine and l-arginine were synthesized and characterized by elemental analysis, IR, electronic spectra, and conductance measurements. The stoichiometry and the stability constants of the complexes were determined spectrophotometrically. The investigated Schiff bases exhibited tridentate coordination mode with the general formulae [Fe(HL)2]·nH2O for ... إقراء المزيد

Systematic in vivo study of NiO nanowires and nanospheres: biodegradation, uptake and biological impacts.
High aspect ratio nanomaterials (NM) have a promising future in medicine and industry as a unique category of NM. Consequently, it is important to evaluate their potential biological side-effects before crediting their use. To understand the mechanisms of degradation, internalisation, and interaction with different biological targets, we used the in vivo model Drosophila melanogaster to obtain a systematic and complete ... إقراء المزيد
