The 3-aminoacetophenone and 4-aminoantipyrine were used as precursors to prepare new six ligands. The three new ligands (L1,L2 and L3) were synthesis by reacting one mole of 3-aminoacetophenone with one mole of (Acetyl chloride), (benzoyl chloride), (4-methoxybenzoyl chloride) and ammonium thiocyanat in acetone as a solvent, they are:- L1 (AAA) =[N-(3-acetylphenylcarbamothioyl)acetamide] L2 (BAA) =[N-(3-acetylphenylcarbamothioyl)benzamide] L3 (MAA) =[N-(3-acetylphenylcarbamothioyl)-4-methoxy benzamide] Also three new derivatives of 4-aminoantipyrine were synthesis by reacting one mole of 4-aminoantipyrine with one mole of (Acetyl chloride), (benzoyl chloride), (4-methoxybenzoyl chloride) and ammonium thiocyanat in acetone as solvent and the ligands are given: L4 (AAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)acetamide] L5 (BAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)benzamide] L6 (MAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)-4-methoxybenzamide] These ligands were identified by FT-IR ,1H,13C-NMR,elemental analysis(C.H.N.S), electronic spectra, the molecular formula of there were concluded:- L1 (AAA) = C11H12O2N2S L2 (BAA) = C16H14O2N2S L3 (MAA) = C17H16O3N2S L4 (AAD) = C14H16N4O2S L5 (BAD) = C19H18O2N4S L6 (MAD) = C20H20O3N4S The ligands were reacted with some metal ions (M+2 =VO, Mn, Co, Ni, Cu, Zn, Cd , Hg and Pd), to give complexes with molecular formulas:- [M(AAA)2(H2O)2]Cl2 , [M(BAA)2(H2O)2]Cl2 , [M(MAA)2(H2O)2]Cl2, [M(AAD)2(H2O)2]Cl2 , [M(BAD)2(H2O)2]Cl2, [M(MAD)2(H2O)2]Cl2 Where (M+2 = Mn, Co, Ni, Cu, Zn, Cd , Hg and Pd) [VO(AAA)2]SO4 , [VO(BAA)2]SO4 , [VO(MAA)2]SO4, [VO(AAD)2]SO4 , [VO(BAD)2]SO4, [VO(MAD)2]SO4 The complexes were characterized by solubility, melting point and decomposition, FT-IR, electronic spectra, molar conductivity, magnetic susceptibility measurements, element microanalysis for some complexes and flame atomic absorption. From above results, one can conclude that complexes of (M+2 = Mn, Co, Ni, Cu, Zn, Cd, Hg and Pd) have an octahedral geometry while the square pyramid for complexes for(VO+2) The biological effects of ligands and some of their complexes have been investigated on two types of bacteria species Staphylococcus aureu a gram positive and Escherichia coli a gram negative In agricultural agar medium, the results exhibited all the compounds (expect Ni2+ with L1)have varsity anti bacterial activities

ABSTRACT: BACKGROUND: Coriandrum Sativum is a native of Mediterranean region and is grown in North Africa, central Europe, and Asia as culinary herb and medicament. In addition to the other health-supporting reputation, coriander has hypoglycemic, hypolipidemic, and aphrodisiac effects. OBJECTIVE: To study the effect of Coriandrum Sativum on process of spermatogenesis. MATERIALS AND METHODS: Coriandrum sativum was given daily to mature male rats in a dose of 50mg/ 100g body weight for 14 days. 10% formalin fixed paraffin-embedded tissue sections were performed for histological and morphometrical studies. RESULTS: Histological study showed wider seminiferous tubules & increased spermatocytes population with an increased sperm density

Background: Rheumatoid arthritis (RA) is a chronic and systemic autoimmune disease that is characterized by severe synovial inflammation, cartilage erosion, bone loss, and generalized vasculopathy. Although the immunologic mechanism of RA is still unclear, it is now thought to be a primarily Th17-driven disease. Along with other factors, IL-23 stimulates the expansion of Th17 cells from naive CD4+ T cells.
Objective: The objective of this study is to assess the circulating levels of interleukin (IL)-23 in rheumatoid arthritis (RA) and determine the correlation between plasma/serum IL-23 levels and disease activity. So, we performed a systematic review with meta-analysis comparing

This study has three parts, the first one is the synthesis of a novel Schiff bases by the condensation of guanine or 9-[{2-hydroxyethoxy}methyl]-9H-guanine with variety aldehydes to yield four different bases as follows: (E)-2-((4-nitrobenzylidene)amino)-1,9-dihydro-6H-purin-6-one (S1), (E)-2-((4-methoxybenzylidene)amino)-1,9-dihydro-6H-purin-6-one (S2), (E)-2-((2-hydroxybenzylidene) amino)-9-((2-hydroxy ethoxy)methyl)-1,9-dihydro-6H-purin-6-one (S3), and (E)-2-(((9-((2-hydroxy ethoxy)methyl)-6-oxo-6,9-dihydro-1H-purin-2-yl)imino)methyl)benzoic acid (S4). Then, spectroscopic analyses such as Elemental Analysis, UV/VIS, Mass spectra, FTIR, 1H,13C-NMR were made to recognize these bases. In the second part, the ability of synthesized bases to

The current work utilizes the peel and pulp of the Iraqi eggplant to remove Alizarin Red S dye (ARS) from an aqueous solution. The isotherms of adsorption were studied and the factors that the effect them: temperature, the effect of surface nature and effect of ionic strength. The isotherms of adsorption of ARS on the peel were found obey the Freundlich, equation, but the isotherms of adsorption on the pulp were found to obey the Langmuir equation. At different temperatures, the adsorption process was studied, and it was found that when the temperature decreased, the adsorption increased. Based on the data we obtained in practice, the thermodynamic functions (∆H, ∆G, ∆S) were calculated as the process was exothermic, spontan
