A Schiff base of 1,3,4-triazole derivative have been synthesized by the reaction
between 5-(4-methylphenyl)-1,3,4-oxadiazole-2-thiol and hydrazine in the presence pyridine as catalyst to yield the 4-amino-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol which was treated with aromatic aldehyde to gave five member heterocyclic ring schiff base called 5-(4-methylphenyl)-4-[(pyridin-2-ylmethylidene)amino]-4H-1,2,4-triazole-3-thiol as di-dentate ligand. The last compound reacted with hydrated metal chlorides NiCl2, CuCl2, CoCl3,CrCl3 and FeCl3 in presence of ethanol as solvent to yield 1,3,4-triazole complexes. The structures of synthesized ligand and their complexes have been established on the basis of their spectral FTIR, Mass,1H-NMR, elemental analysis C,H,N as well as Molar conductance .The purity of the compounds was confirmed by TLC

Chalcone derivative were synthesized by reaction of some benzaldehyde derivatives with acetophenone or substituted. Then the products were reacted with hydrazine hydrate, semicarbazide and phenyl hydrazine, to give the heterocyclic derivatives of pyrazole to use preparation monomers from acid chloride to give polymers by free radicals. The structure of these compounds characterized by FT-IR, 1H-NMR spectra, melting points, TLC, Vis, Uv/Vis and X-ray, These compounds were also screened for their antibacterial activities.

Vitamin D deficiency and anemia are common in the Middle East, and
vitamin D deficiency and hyperparathyroidism have been study to be linked with an
increased incidence of anemia. In this study, that vitamin D deficiency and hyperpara
thyroidism may be connected with anemia in female Iraqi population was tested.

Polycystic ovary syndrome (PCOS) is a common gynecologic
endocrinopathy. The pathogenesis of PCOS is associated with both heredity and
environment. PCOS has adverse impacts on female endocrine, reproduction, and
metabolism. PCOS can impact women’s reproductive health, leading to anovulatory
infertility and higher rate of early pregnancy loss. PCOS has additional metabolic
derangements, such as insulin resistance, impaired glucose tolerance, and
dyslipidemia. The risks of diabetes, cardiovascular disease, hypertension, metabolic
syndrome, and endometrial cancer among PCOS patients are significantly increased
as well. C-reactive protein (CRP) is a member of a group of acute phase of protein
which increase their concentrations during certain inflammation disorders and used as
a biomarker of inflammation in the body. The aim of the presented work is to
determine the level of CRP and then to evaluate its correlation with total antioxidant
capacity in sera of women with PCOS.

The corrosion inhibition effects of cefixima and aminobenzylpenicillin drug
inhibitors in 0.05M deaerated sulfuric acid solution for carbon steel have been
studied by using electrochemical techniques and quantum chemical calculations
as well as scanning electron microscope (SEM). It is observed from the
experimental findings that both compounds perform as good inhibitors and
behave according to mixed type inhibitor in terms of their inhibitory action.
Additionally, it was found the percentage of corrosion inhibition become
maximal when the concentrations of the cefixima and aminobenzylpenicillin
inhibitors are increased. The influence of temperature on the corrosion of
carbon steel has been investigated and the activation energy values estimated.
The corrosion efficiency decreases with increasing the temperature range. The
parameters of thermodynamic have been determined and indicate that the
adsorption mechanism follows the Langmuir isotherm model and forms a
protective layer on carbon steel surface electrode, which was characterized by
scanning electron microscope measurements, to prevent a corrosion process.
Quantum chemical calculations have been performed to provide evidence for
corrosion inhibition according to the chemical structures of the cefixima and
aminobenzylpenicillin drug inhibitors.

Simple Spectral method was developed to estimate the methyl and
propyl paraben through charge- transfer (CT) complexes. The method
involves the interaction of parabens compounds with o-chloranil as π
acceptor. Under the optimized conditions, the complexes were found to be
absorbed at 415 and 385 nm with in the linearity range of 5-40 and 5-55 μg
ml-1 respectively. The molar absorptivity values were in the range 3803.75
and 2342.6 L.mol-1.cm-1 respectively. And the lower limit of detection were in
the rang 0.073 and 0.086 µg/ml-1 for methyl and propyl respectively. The
stoichiometry of the paraben compounds o-chloranil complexes was found to
be 1:1 method. The procedure was characterized by its simplicity with
accuracy and precision. The proposed method was applied successful in some
detergents (shampoo and lotion) containing paraben compounds.
