Abstract<p>Monomeric complexes of the ligand H<sub>2</sub>L, with the general formula [M (HL<sub>2</sub>)<sub>2</sub>] with (M (II) = Co, Ni, Cu), have been synthesized and characterized by proton nuclear magnetic resonance (<sup>1</sup>H‐NMR), Fourier‐transform infrared spectroscopy (FT‐IR), ultraviolet–visible spectroscopy (UV‐Vis), elemental microanalysis, metal content, magnetic moment and molar conductance measurements, molar conductance, and chloride containing. On the basis of experimental evidences, tetrahedral geometry has been proposed for prepared Schiff bases complexes. The geometry of the ligand and its complexes were confirmed by their optimized structures obtained from the computational study. Antioxidant activities of these compounds were evaluated against 1.1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical and were compared with standard natural antioxidant, ascorbic acid. The results reveal that these compounds exhibit excellent radical scavenging activities.</p>

...Show More Authors
Abstract<p>Renal failure is a disease of the kidney, in which the renal excretory function is failed to process due to depression of the GFR. Renal failure is divided into acute and chronic depending on the period of the disease. The study was designed to investigate the level of oxidative stress in RF patients. Seventy-five subjects had enrolled in the study, who divided into three groups equally, in which they are healthy control, ARF patients, and CRF patients. The results had shown a significant <italic>(P<0.01)</italic> increase in the level of TOS for RF patients when compared with control. Also, a significant difference in the level of TOS has been observed between ARF and CR</p> ... Show More

Synthesis and Characterization of [Benzyl (2-hydroxy-1naphthylidene) hydrazine carbodithioate] and Its Metal Complexes With [Co(II), Ni(II), Cu(II), Zn(II), and Cd(II)] Ions
...Show More Authors

  The formation of  Co(II), Ni(II), Cu(II), Zn(II), and Cd(II)-complexes (C1-C5) respectively was studied with new Schiff base ligand [benzyl(2-hydroxy-1-naphthalidene) hydrazine carbodithioate  derived from reaction of  2-hydroxy-1-naphthaldehyde and benzyl hydrazine carbodithioate. The suggested structures of the ligand and its complexes have been determined   by using C.H.N.S analyzer, thermal analysis, FT-IR, U.V-Visible, 1HNMR, 13CNMR , conductivity measurement , magnetic susceptibility and atomic absorption. According to these studies,  the ligand coordinates as  a tridentate with metal ions through nitrogen atom of azomethane , oxygen atom of  hydroxyl, and  sulfur atom of thione

Four complexes of Co(II),Ni(II),Cu(II) and Zn(II) with the azo ligand (4-chloro-N-(2-(dimethylamino)ethyl)-5-((2-hydroxy- 4,6-dimethylphenol)diazenyl)-2-methoxybenzamide) L. The structure of ligand and complexes were confirmed on the basis of their analytical and spectral data, these dyes were tested as dyeing in cotton fabric, and also testing in light and cleaner firmness. Also, antimicrobial and antifungal activities of ligand and their complexes were evaluated and the results showed that the ZnL compound showed the higher antibacterial activity with inhibition zone of 13mm against Staphyloco-ccus epidermidis, Steptococcus sp. and Escherichia coli compared with ligand and other metal complexes .In case of ZnL compound the antifungal acti

The antiphytopathogenic effects of the crude methanol extract of Cladophora glomerata (Lin.) Kützing (Cladophoraceae) which isolated from Al Rashidiya region at north of Baghdad was investigated against two type of plant fungi (Pythium altimum and Rhizoctonia solani) which causes damping off disease where isolated from covered cucumber field in Al-Alyosifia region. Hot methanol extract showed antifungal activity against the two species of fungi in different concentrations(10,25,50 mg/ml) of extract to Cladophora glomerata as percentage inhibition (51.63 ,72.8 ,83.71) and (56.18 ,77.41 ,100)comparing with Pythium altimum and Rhizoctonia solani respectively .primary detection of active compounds showed that macroalgae (Cladoph

Determination of Enzymatic Antioxidant in Iraqi Patients with Chronic Gastritis
...Show More Authors

Infection of the gastric mucosa with Helicobacter pylori is strongly associated with chronic gastritis, peptic ulcer and gastric cancer. Helicobacter pylori virulence factors include a variety of proteins that are involved in its pathogenesis, such as VacA and CagA. Another group of virulence factors is clearly important for colonization of H.pylori in the gastric mucosa. These include urease, motility factors (flagellin), and Superoxide dismutase (SOD). Because of this organism's microaerophilic nature and the increased levels of reactive oxygen in the infected host, we expect that other factors involved in the response to oxidative stress are likely to be required for virulence. Superoxide dismutase is a near
