Abstract

The quantum chemical calculations were performed for four organic molecules differ in the number and type of hetero atoms namely1,2-di(1H-benzo[d]imidazol-2-yl)ethane(DBIE); 1,2-di(benzo[d][1,3]dithiol-2-yl)ethane(DBTE);1,2-di(benzo[d][1,3]dioxol-2-yl)ethane(DBOE);and(E)-Nꞌ-(benzo[d][1,3]dioxol-2-ylmethyl)-N-(benzo[d][1,3]dithiol-2-yl) formimidamide (BDBF). Their efficiency as inhibitors for iron corrosion were evaluated in two phases, the first is a studying of molecular structure effect and its physic-chemical properties which included the molar refractivity, lipophilicity coefficient(logP),molecular electrostatic potential(MEP), molecular volume, molecule surface area and molecular polarizability(pol). Either second phase comprised studying electronic characteristics of molecules such as energy of the highest occupied molecular orbital EHOMO, the energy of the lowest unoccupied molecular orbital ELUMO, ∆EBack−donation , dipole moment (μ), ∆Egap, global softness (σ), global hardness(η), number of transferred electrons(ΔN), global electrophilicity(ω), chemical potential (

Abstract

The synthesis and characterization of some novel pyrimidine derivatives has been presented. pyrimidines have been prepared from 1,6-diphenylhexa-1,5-diene-3,4-dione by treating with urea. The structure of pyrimidines has been characterized by spectral analysis by FT-IR, elemental analysis (C.H.N.) and 1H NMR spectroscopy.

Abstract

Thyroid gland is one of the most important endocrine glands in the body that regulates a wide array of parameters such as lipid profiles, homocystein and malandialdehyde level. The present study included 50 patients with thyroid dysfunction and equal number matched healthy control. The results obtained from the present study, Have reported a significant increase in (TC, TG and LDL) level and significant decrease in level of HDL at (p<0.01) in the Hyperthyroidism patients compared with control. while in the hyperthyroidism the data in this study show significant decrease in the level of TG and LDL(P<0.01) and increase HDL level at (p<0.01) compared with control. While No significant difference was shown in TC level in hyperthyroidism. Furthermore, this study showed high significant for MDA level (p<0.01) in both hypo and hyperthyroidism compared with control . in this work, there was significantly increased (P<0.01) in serum HOMS in hypothyroidism compared with control, and no significantly in hyperthyroidism. Moreover , the results showed significant decrease TSH level and significant increase T4 and T3 at (P<0.01) in hyperthyroidism compared with control. the study has also reported significant elevation for TSH level and significant lower for T4 and T3 at (P<0.01) in hypothyroidism compared with control .
