Synthesis, spectral characterization and thermal ‎study of complexes of ions of some metallic ‎elements with new cyclic ligands
...Show More Authors

The purpose of my thesis is to prepare four new ligands (L1-L4) that have been ‎used to prepare a series of metal complexes by reacting them with metal ions:‎ ‎ M=(Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II) ‎ ‎ Where succinyl chloride was used as a raw material for the preparation of ‎bi-dented ligands (L1-L4) by reacting it with potassium thiocyanate as a first ‎step and then reacting with (2-aminobenzothiazole, Benzylamine, 4-‎aminoantipyrine, Sulfamethoxazole) respectively as a second step with the use ‎of dry acetone as a solvent, the chemical formula of the four ligands prepared in ‎succession:‎ N1,N4-bis(benzo[d]thiazol-2-ylcarbamothioyl)succinamide (L1)‎ N1,N4-bis(benzylcarbamothioyl)succinamide (L2)‎ N1,N4-bis((1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) ‎carbamothioyl)succinamide (L3)‎ N1,N4-bis((4-(N-(5-methylisoxazol-3-yl)sulfamoyl) phenyl) carbamo thioyl) ‎succinamide (L4)‎ ‎ The new ligands were identified using spectroscopic measurements that ‎included (FT-IR spectra, UV-Vis spectra, and nuclear magnetic resonance (1H, ‎‎13CNMR) spectra, mass spectra, elemental analysis (C.H.N.S), and thermal ‎analysis (TGA&DSC), as the results of the measurements proved to be identical ‎to the proposed molecular formula for these ligands.‎ ‎ A series of metal complexes for ligands was also prepared, which included ‎seven complexes for each ligand, by adding each of the metal ions to the four ‎ligands prepared in succession to produce the following molecular formulas: -‎ ‎[M2(L)Cl4] , L= L1, L2, L3, L4‎ ‎(M= Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II))‎ ‎ The prepared complexes were diagnosed by several techniques, including the ‎study of the infrared spectra of the prepared complexes, and when comparing ‎those spectra with the spectra of each of the four ligands prepared in the free ‎form, these gave clear changes, including the emergence of a new band within ‎the fingerprint area. It was not originally present in the spectra of ligands in ‎their free form, and this is due to the occurrence of coordination between the ‎metal ions under study and the donor atoms, which are the oxygen atom of the ‎‎(C=O) group, and the sulfur atom of the (C=S) group in the ligands. (L1-L4), ‎while other distinct bands were obtained with clear changes in shape, intensity, ‎and location, and this is an indication of the occurrence of a coordination ‎process between the metal ions under study and the four prepared ligands.‎ ‎ The percentage of metal ions in the prepared complexes was determined by ‎flame atomic absorption spectrometry, where it was shown from the careful ‎analysis of the elements the great agreement between the percentages calculated ‎theoretically and obtained practically.‎ ‎ The magnetic sensitivity results showed that some of the prepared metallic ‎complexes have paramagnetic properties.‎ The measurements of the molar conductivity of the prepared complexes ‎dissolved in DMSO at a concentration of 1×10-3 M and at the laboratory ‎temperature showed that they are of a non-electrolytic nature.‎ ‎ The prepared complexes were also studied through solubility, melting point, ‎and ultraviolet-visible techniques, and through the data of all the ‎aforementioned techniques, structural formulas were proposed for the prepared ‎complexes, through which it was found that the prepared ligands are bivalve ‎chelating ligands that lead to their participation as ligand into complexes with a ‎tetrahedral geometric shape for all metallic complexes under study.‎ ‎ The research included a study evaluating the antioxidant activity of some ‎selected metal complexes by studying the amount of radical scavenging of ‎DPPH* compared to ascorbic acid as an antioxidant reference agent. The zinc ‎complex showed higher activity than the nickel complex compared to standard ‎ascorbic acid. The [Cu2(L1)Cl4] and [Co2(L1)Cl4] complexes were also tested as ‎antibodies to inhibit the breast cancer cell line (MCF-7) and compared with the ‎normal cell line (HdFn), where the copper complex showed the ability to inhibit ‎the cancerous cell line compared with the cobalt complex. ‎ ‎ The molecular binding of ligands (L3) and (L4) was also studied, and their ‎possibility of using them as drugs in the treatment of some diseases, where the ‎ligand L3 showed better association with the active site of the enzyme than the ‎ligand L4, and is expected to highest antimicrobial effect. ‎ ‎ Finally, the biological effect of the prepared ligands and some of their ‎complexes on the growth of two types of bacteria, Escherichia coli and ‎Staphylococcus aureus, was studied using DMSO solvent, where the complexes ‎showed greater activity than the ligands against the selected types of bacteria. ‎‏

Resveratrol protects mice against SEB‐induced acute lung injury and mortality by miR‐193a modulation that targets TGF‐β signalling
...Show More Authors
Abstract<p>Staphylococcal enterotoxin B (SEB) is a potent superantigen produced by <italic>Staphylococcus aureus</italic> that triggers a strong immune response, characterized by cytokine storm, multi‐organ failure, and often death. When inhaled, SEB can cause acute lung injury (ALI) and respiratory failure. In this study, we investigated the effect of resveratrol (RES), a phytoallexin, on SEB‐driven ALI and mortality in mice. We used a dual‐exposure model of SEB in C3H/HeJ mice, which caused 100% mortality within the first 5 days of exposure, and treatment with RES resulted in 100% survival of these mice up to 10 days post‐SEB exposure. RES reduced the inflammatory cytokines in the serum an</p> ... Show More

Diabetic kidney disease (DKD) is caused by a variety of processes. As a result, one biomarker is insufficient to represent the complete process. This study Evaluate the diagnostic value of serum kidney injury molecule-1(KIM-1) and cystatin C (CysC) as early biochemical markers of DKD and predictive their sensitivities and specificities as biomarkers of nephropathy in Iraqi type 2 diabetic (T2DM) patients. This cross-sectional study include 161 T2DM patients from Diabetes and Endocrinology Center at Merjan medical city in Babylon. Patients divided according to urinary albumin creatinine ratio(ACR) (Group1:ACR≤30mg/g,Group2:ACR>30mg/g). Random spot urine and fasting blood samples were taken from each patient and urinary ACR, bloo

Artistic Features Of Re-Writing The Novel "On The Eve, on The Eve" By YevgueniBobov: As an Example: Жанровые Особенности Ремейка (На Материале Романа Е. Попова «Накануне Накануне»)
...Show More Authors

 The paper tackles two topics. The first is about the term "Ремейк" which is very common in contemporary Russian literature; it has counterparts such as " Обработка" and " Переделка", where these two may indicate any of the following meanings (remake, reformulate, rewrite, treatment, modification, change). It has been shown that this term does not have a stable definition. Also, the role of this term in literary studies has been mentioned along with how it has come to its peak of use in post-modern literature.

The second is that I have taken a sample of well-known works in Russian literature " On the Eve, On the Eve " by the contemporary Russian writer YevgueniBobov, and shown the effort of the writer
