To answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. In the present paper, controlled metal based drug (Pd(II) complex) release manner of β‑Lactoglobulin (β-LG) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...
A new series of transition metal complexes of Co(II), Ni(II), Cu(II) and Zn(II), has beensynthesized from the Knoevenagel condensate Schiff base ligand(L) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. Structural features were determinedby spectral and analytical techniques. Square-planar geometry has been adopted by thecomplexes except cobalt complex which ...
A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhed...
the role of cu, zn and co in human physiology is well documented. isatin and glycine have inhibitory effects on central nervous system. to capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. the cu (ii) complex was found to be most active among the compounds. the compounds were screened against staphylococcus aureus, escheric...
Background and Objective: Photodynamic therapy is a treatment that uses photosensitizer and intense visible light. When photosensitizers get exposed to a specific light wavelength (preferentially in the red region), they produce reactive oxygen species that are toxic to cells. Recently, attention has been focused on porphyrins and their analogs as photosensitizers. Zn (II) tetrapyridinoporphyra...
In this paper, nickel oxide (NiO) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(II) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II) chloride, [NiL]Cl2, in an electrical furnace at optimal temperature, 450 ºC for 3.5 h. The nickel(II) complex is obtained via solid state synthesis using nickel(II) chloride and tetradentate O4 acyclic ligan...

determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
in this work application of seven synthetic polymers as adsorbents for the removal of hg(ii) from aqueous solution was studied. the equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. variations of hg(ii) concentration in solution have been studied through measur...
Nowadays, the subject of vision metrology network design is local enhancement of the existing network. In the other words, it has changed from first to third order design concept. To improve the network, locally, some new camera stations should be added to the network in drawback areas. The accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...
