Estimation of Parameters for the Gumbel Type-I Distribution under Type-II Censoring Scheme
...Show More Authors

This paper aims to decide the best parameter estimation methods for the parameters of the Gumbel type-I distribution under the type-II censorship scheme. For this purpose, classical and Bayesian parameter estimation procedures are considered. The maximum likelihood estimators are used for the classical parameter estimation procedure. The asymptotic distributions of these estimators are also derived. It is not possible to obtain explicit solutions of Bayesian estimators. Therefore, Markov Chain Monte Carlo, and Lindley techniques are taken into account to estimate the unknown parameters. In Bayesian analysis, it is very important to determine an appropriate combination of a prior distribution and a loss function. Therefore, two different prior distributions are used. Also, the Bayesian estimators concerning the parameters of interest under various loss functions are investigated. The Gibbs sampling algorithm is used to construct the Bayesian credible intervals. Then, the efficiencies of the maximum likelihood estimators are compared with Bayesian estimators via an extensive Monte Carlo simulation study. It has been shown that the Bayesian estimators are considerably more efficient than the maximum likelihood estimators. Finally, a real-life example is also presented for application purposes.

New White Method of Parameters and Reliability Estimation for Transmuted Power Function Distribution
...Show More Authors

        In this paper, an estimate has been made for parameters and the reliability function for Transmuted power function (TPF) distribution through using some estimation methods as proposed new technique for white, percentile, least square, weighted least square and modification moment methods. A simulation was used to generate random data that follow the (TPF) distribution on three experiments (E1 , E2 , E3)  of the real values of the parameters, and with sample size (n=10,25,50 and 100) and iteration samples (N=1000), and taking reliability times (0< t < 0) . Comparisons have been made between the obtained results from the estimators using mean square error (MSE). The results showed the

Estimation of the parameter of the Pareto distribution manual Using the general mediator estimator
...Show More Authors

Estimation of the tail index parameter of a one - parameter Pareto model has wide important by the researchers because it has awide application in the econometrics science and reliability theorem.

Here we introduce anew estimator of "generalized median" type and compare it with the methods of Moments and Maximum likelihood by using the criteria, mean square error.

 The estimator of generalized median type performing best over all.

Prevalence of immunological marker (Anti-GAD) in patients with type 1 diabetes : hospital based study
...Show More Authors

Background: type 1diabetes (T1DM) is a form of diabetes mellitus that results from  autoimmune  destruction of insulin-producing beta cells of the pancreas, leading to permanent insulin deficiency ,categorized as either being positive or negative for various auto antibodies related to pancreatic function .An anti glutamic acid decarboxylase autoantibody(Anti-GAD) is recognized as one of the major serological markers for type 1 diabetes mellitus.

Objectives: to determine the prevalence of the immunological marker  (Anti-GAD) among a sample of type1diabetus mellitus patients and to identify some factors that might be associated with its seroposivity.

Method:

The Bayesian Estimation for The Shape Parameter of The Power Function Distribution (PFD-I) to Use Hyper Prior Functions
...Show More Authors

The objective of this study is to examine the properties of Bayes estimators of the shape parameter of the Power Function Distribution (PFD-I), by using two different prior distributions for the parameter θ and different loss functions that were compared with the maximum likelihood estimators. In many practical applications, we may have two different prior information about the prior distribution for the shape parameter of the Power Function Distribution, which influences the parameter estimation. So, we used two different kinds of conjugate priors of shape parameter θ of the <

Background: Breast cancer is one of the common malignancies among women worldwide. Human papillomavirus (HPV) infections have been linked to many human cancers in addition to cervical cancer and one of them is breast cancer.
Objective: To investigate the presence of human papilloma virus type 6 and type 11in breast cancer tissue specimens by in situ hybridization technique.
Patients and Methods: Thirty four formalin-fixed, paraffin embedded tissue blocks from breast cancer patients were obtained from the archives of the pathology laboratory of Al-Yarmouk Teaching Hospital from January 2011 to July 2012. In addition formalin-fixed, paraffin embedded blocks tissue for twenty fibroadenoma of breast were collected and used as control g

Correlation of Serum levels of Chromium, Copper, and Manganese with the Glucose levels in Type 2 Diabetes Mellitus in Ira

Background: The metabolism of many trace elements such as chromium, copper, and manganese were reported to be altered in type 2 diabetes militates. This element may have specific roles in the pathogenesis and progress of this disease.

Objectives: To evaluate the serum levels of copper, chromium, and manganese in type 2 diabetic patients in Iraq. 

Patients and Methods: This case-control study included 100 type 2 diabetic patients, 35-60 years old, with high BMI as cases, and 100 non-diabetic subjects as controls who were healthy

Inflammatory markers mediated diabetic nephropathy in patients with type 1 and type 2 diabetes mellitus
...Show More Authors

Background: Diabetic nephropathy (DN) represents the most common cause of end stage renal disease (ESRD) worldwide. Diabetic nephropathy occurs as a result of an interaction between hemodynamic and metabolic factors, however recent evidence shows an increase growing support for the notion that inflammation plays a key role in the pathogenesis of diabetic nephropathy.
Objectives: To speculate the role of IL-18 and TNF-α proinflammatory cytokines in the initiation and development of diabetic nephropathy in T1DM and T2DM.
Materials and methods: Eighty seven T1DM and T2DM patients with or without DN were enrolled. IL-18 and TNF-α cytokines were measured by solid phase immunosorbent assays.

investigation. Five permanent molar teeth were extracted from adult individuals for different reasons
(tooth impaction, periodontal diseases, and pulp infections); their ages were ranging from 20-25 years
old. Different carious teeth with varying clinical stages of caries progression were examined. An

Erythrocyte Magnesium Levels in type I and type II Iraq diabetic patients effect of antidiabetic treatment
...Show More Authors

Background: Direct measurement of intracellular magnesium using erythrocytes has been suggested as a sensitive indicator for the estimation of body magnesium store. Marked depletion in plasma and erythrocyte magnesium levels was particularly evident in diabetic patients with advanced retinopathy and poor diabetic control. While insulin has been shown to stimulate erythrocyte magnesium uptake, hyperglycemia per se suppressed intracellular magnesium in normal human red cells.
Aim of the study: To investigate the erythrocyte magnesium level in Iraqi type I and II diabetic patients, with specific emphasis on the effect of both, metabolic control and the type of antidiabetic treatments.
Methods: Sixty two diabetic patients (7 with type
