Background: Oral Lichen planus (OLP) is a T-cell mediated chronic inflammatory oral mucosal disease of unknown etiology. Recent studies have reported an increased oxidative stress and lipid peroxidation in such patients. This suggests that reactive oxygen species may have a role in the pathogenesis of lichen planus. Oxidative stress in OLP release molecules consisting of granzymes resulting in local tissue damage in the effectors. Antioxidants that can defend against oxidative stress in the body cells include enzymes, as well as non- enzymatic antioxidants, such as melatonin, uric acid, vitamin A and E. Purpose: To study the level of salivary vitamin E and uric acid as antioxidant agents in patients with OLP and compared with healthy con

Alopecia areata is considered as a major health problem, its importance is attributed to its
recent increased incidence in our population. Till now, there is no exact cause for alopecia areata
although researchers thought it's an autoimmune disease.
This clinical study was designed to evaluate the role of trace elements (zinc and copper) in patients
with alopecia areata. Twenty patients were diagnosed as having alopecia areata with an age range
(10-40 years) were involved in this study. Normal subjects of the same age group were also
evaluated as control. The level of serum Zn and Cu were measured by flame atomic absorption
spectrophotometry in both control and patient group. And the ratio of Zn/Cu was also estimated

In this paper, a mathematical model consisting of a prey-predator system incorporating infectious disease in the prey has been proposed and analyzed. It is assumed that the predator preys upon the nonrefugees prey only according to the modified Holling type-II functional response. There is a harvesting process from the predator. The existence and uniqueness of the solution in addition to their bounded are discussed. The stability analysis of the model around all possible equilibrium points is investigated. The persistence conditions of the system are established. Local bifurcation analysis in view of the Sotomayor theorem is carried out. Numerical simulation has been applied to investigate the global dynamics and specify the effect

The study targets exploring the similarities and differences between Iraqi and Malaysian learners of English in refusing marriage proposals. Also, it examines the favored politeness strategies that learners use to protect their interlocutors’ face, heeding both their social distance and status. Data were gathered by a Discourse Completion Task (DCT) which contained six marriage situations. Responses were analyzed based on Beebe et al.’s (1990) refusal taxonomy and Scollon et al.’s (2012) politeness system. The findings indicated that both the Iraqi and Malaysian learners preferred the indirect refusal strategies in marriage proposals, as well as the hierarchical politeness in the form of independence strategies regardless of t

Background : Obesity and insulin resistance have been quite well recognized as fundamental and leading causes of major health issues such as diabetes, hyperlipidemia, hypertension, and cardiovascular diseases. Abdominal obesity, particularly visceral adiposity is considered to play a major role in causing insulin resistance and type 2 diabetes mellitus , T2DM
The resistin is considered one of the causes of insulin resistance which lead to hyperinsulinemia and a decrease in the quantitative insulin sensitivity check index (Quicki)
which has been recently reported to be a useful marker of insulin resistance in patients with T2DM.
Objective : The aim of the present study is to find the relationship between

Abstract: Background: Prediabetes and are increasing in prevalence all over the world, they each carry risks to the future development of diabetes mellitus and cardiovascular disease. These risks will be greatly exaggerated if they occur together in the same individual. The aim of the study was to find the prevalence and the association of prediabetes and metabolic syndrome, in addition to analyzing the correlation of the risk factors that lead to their development. Material and Methods: This was a cross-sectional, simple random study that included 300 Iraqi individuals, aged between 30-75 years, who accepted to take part in this study were recruited. Result: Prevalence of prediabetes and metabolic syndrome was (33.66%) and (42%) r

Analysis of the main financial statements (financial position, income, cash flow) using the analysis tools gives a clear picture of the results of the annual activity of the economic units, which contribute to the development of future plans and programs and identify weaknesses in the work of economic units including banks. Therefore, the indicators used in the analysis Would be feasible for the rest of the other sectors. such as Central Bank , Security exchange market , which will accordingly contribute in National product , determining market requirements , investor’s desires , knowing economic situation and providing liquidity in a timing manner.

The current research aims know:

1.-level application managers secondary schools and junior high for the tasks set by the high school system in Iraq, from the standpoint of teachers.

2. statistically significant differences in the extent of the application of secondary school principals and junior high for the tasks set by the high school system from the viewpoint of teachers depending on the variable (sex, specialty, number of years of service).

The researcher used the descriptive analytical method being considered best suited to such studies, for the purpose of achieving the goals of research, the researcher using the questionnai

  The aim of the research is to highlight the income tax by direct deduction in Iraq and the most important problems and obstacles faced by this type of taxes and identify the reasons for the clear and striking differences in the deduction between those charged with the state departments to reach the exact calculation in accordance with the laws and instructions and the unification of tax deductions for similar cases and clarify Cases of confusion and ambiguity, and achieving justice by deduction, whether in favor of the taxpayer or financial authority. Under the laws and regulations in force.
