he study aimed to purify of Leucine aminopeptidase (LAP) from sera of hyperthyroidism patients and its relation to some thyroid hormones (TSH, T 3 , T 4 ) of subclinical hyperthyroidism and hyperthyroidism patients with lipid peroxidation levels that may be play a role in this diseases. Specimens were collected during the time from Nov 2017 until Jan 2018 from Endocrine and Diabetes Center, blood samples were collected from fifty healthy control and one hundred patients, patients were divided into two groups consisted of (50) with hyperthyroidism and (50) with subclinical hyperthyroidism. The aged for all subjects ranged (15-60) years with body mass ranged ((25- 29) kg/m 2 . The purification is done by addition of ammonium sulfate, dialysis, ion exchange chromatography by using DEAE -Sepharose and gel filtration chromatography by using Sepharose 6B. FT3, FT4, TSH, LAP, peroxynitrite, malondialdehyde were determined. Results showed the precipitate and concentrated protein appeared five peaks after eluted with Tris- HCl (50 mM, pH 7.0 in ion exchange column, LAP located in the first peak (wash fraction) and the second peak (elution fraction eluted with 0.1 M NaCl), also, results showed single peak for both first and second peaks after eluted in gel filtration chromatography following steps by using sodium dodecyl sulfate-polyacrylamide gel. As well as results showed a non- significant elevation in BM, FT 3 and FT 4 in subclinical-hyperthyroidism group when compared to the control group. And a highly significant elevation in LAP, peroxynitrite and MDA levels in the patient group compared to the control group, while a highly significant decrease in TSH levels was found in the patient group compared to the control group. Results showed a non-significant elevation in BMI in hyperthyroidism group when compared to the control group., also, showed a highly significant elevation in FT3, FT4 LAP, peroxynitrite and MDA levels in the patient group compared to the control group, while a highly significant decrease in TSH levels was found in the patient group compared to the control group. From this study, it is concluded Leucine aminopeptidase which partial purification from sera of hyperthyroidism patients by ion exchange chromatography and gel filtration chromatography have two isoenzymes ,also, concluded a highly significant elevation in LAP, peroxynitrite and MDA levels in the patient group compared to the control group , in addition to their correlation with thyroid hormone in the patient group, compared to the control group indicate that these parameters have an effect on these diseases.

Background: Bone defect healing is a multidimensional procedure with an overlapping timeline that involves the regeneration of bone tissue. Due to bone's ability to regenerate, the vast majority of bone abnormalities can be restored intuitively under the right physiological conditions. The goal of this study is to examine the immunohistochemistry of bone sialoprotein in order to determine the effect of local application of bone sialoprotein on the healing of a rat tibia generated bone defect. Materials and Methods: In this experiment, 48 albino male rats weighing 300-400 grams and aged 6-8 months will be employed under controlled temperature, drinking, and food consumption settings. The animals will be subjected to a surgical procedure o

The construction project is a very complicated work by its nature and requires specialized knowledge to lead it to success. The construction project is complicated socially, technically and economically in its planning, management and implementation aspects due to the fact that it has many variables and multiple stakeholders in addition to being affected by the surrounding environment. Successful projects depend on three fundamental points which are cost-time, performance and specifications. The project stakeholder's objective to achieve best specifications and the cost-time frame stipulated in the contract.
The question is, was the optimum implementation accomplished? The provision for the success of the project
... Show MoreThe corrosion of carbon steel in single phase (water with 0.1N NaCl ) and two immiscible phases (kerosene-water) using turbulently agitated system is investigated. The experiments are carried out for Reynolds number (Re) range of 38000 to 95000 corresponding to rotational velocities from 600 to 1400 rpm using circular disk turbine agitator at 40 0C. In two-phase system test runs are carried out in aqueous phase (water) concentrations of 1 % vol., 5 % vol., 8% vol., and 16% vol. mixed with kerosene at various Re. The effect of Reynolds number (Re), percent of dispersed phase, dispersed drops diameter, and number of drops per unit volume on the corrosion rate is investigated and discussed. Test runs are carried out using two types of

In this work, a weighted H lder function that approximates a Jacobi polynomial which solves the second order singular Sturm-Liouville equation is discussed. This is generally equivalent to the Jacobean translations and the moduli of smoothness. This paper aims to focus on improving methods of approximation and finding the upper and lower estimates for the degree of approximation in weighted H lder spaces by modifying the modulus of continuity and smoothness. Moreover, some properties for the moduli of smoothness with direct and inverse results are considered.

Background: Considering the antioxidant, anti-inflammatory, and antimicrobial properties of green tea, this study aimed to evaluate the histopathological effect of the sulcular irrigation of green tea extract in the treatment of experimental gingivitis in rabbit.
Materials and methods: For this experimental study, 45 male rabbits, separated in two groups, control non- irrigated group (5rabbits) and study group (40 rabbits), gingivitis induced by ligatures was packed subgingivally in the lower right central incisors of the experimental group for seven days. Then, the animals were randomly designated to two irrigated groups (20 rabbits
