The Effect of Mercuric Exposure on Oxidative Stress and Enzymatic Antioxidant Defense System

 Throughout the centuries, several incidents of mercury toxicity have been reported. Mercury is found in many industries such as battery, thermometer and barometer manufacturing, in the agricultural industry is used in fungicides and in medicine, mercury is used in dental amalgams. An important mechanism involved in cellular injury is induced by exposure to different forms of mercury involves in the induction of oxidative stress.      This study was conducted on non-smoker, male working in a chloroalkali plant for different periods, all workers were not suffering from chronic disease. Healthy non-smoker males that are not exposed, matched age were used as controls(C), workers aged (22-61) years, they were divided into three groups: G1: workers with exposed period less than 10 years, G1 < 10 years. G2: workers with exposed period (10-19) years . G3: included workers with exposed period more than 19 years, G3 > 19 years.     The result we had through examining the different parameters led us to add another group which included individuals with high mercury levels regardless the occupation period, in this group we found high significant changes in the defense system parameters that we measured.      This study showed an elevation in MDA levels in all workers group, specially those with high level mercury , which were 9.31, 12.78, 12.99, 14.73, and 18.11nmol/dl for C, G1, G2 , G3 ,and high level mercury workers respectively .      No alteration was found in SOD activity in erythrocyte (0.67, 0.73, 0.72, and 0.77 U/g.Hb) for C, G1, G2 and G3 respectively.       There were highly significant decrease in catalase activity (P < 0.001) in erythrocyte of all worker groups compared to normal control. The values were (1.5, 0.8, 0.88, 0.815 and 0.45 U/gm/Hb) for C, G1, G2, G3 and G4 respectively. While there were high elevation in glutathione S-transferase activity in worker groups compared to control (P < 0.001) and values were (1.85, 2.589, 2.441, 2.776 and 3.2 U/gm.Hb) for C, G1, G2 and G3 respectively.

EXPOSURE TO TELEVISION PROMOTION OF PHARMACEUTICAL PRODUCTS AND TRENDS TOWARDS THEM / FIELD RESEARCH FOR A SAMPLE OF THE AUDIENCE IN THE CITY OF BAGHDAD: EXPOSURE TO TELEVISION PROMOTION OF PHARMACEUTICAL PRODUCTS AND TRENDS TOWARDS THEM / FIELD RESEARCH FOR A SAMPLE OF THE AUDIENCE IN THE CITY OF BAGHDAD

A field study was conducted on a sample of the public in Baghdad to study the audience's exposure to the television promotion of pharmaceutical products and their trends in order to determine the rate of exposure of the public to the television promotion of pharmaceutical products according to the theory of uses and rumors and to determine the public's attitudes towards television promotion of pharmaceutical products. A survey of (25) a questions was distributed to a sample of the audience of 150 people. The statistical program SPSS was used to unload the data and for the calculation of frequencies and percentages and correlation coefficients. The research reached several results, Most importantly, the television promotion is well receiv

The Effect of Using an Accounting Information System Based on Artificial Intelligence in Detecting Earnings Management to Enhance the Sustainability of Economic Units

This research aims to clarify the importance of an accounting information system that uses artificial intelligence to detect earnings manipulation. The research problem stems from the widespread manipulation of earning in economic entities, especially at the local level, exacerbated by the high financial and administrative corruption rates in Iraq due to fraudulent accounting practices. Since earning manipulation involves intentional fraudulent acts, it is necessary to implement preventive measures to detect and deter such practices. The main hypothesis of the research assumes that an accounting information system based on artificial intelligence cannot effectively detect the manipulation of profits in Iraqi economic entities. The researche

Synthesis and antioxidant activities of Schiff bases and their complexes: a review

Schiff bases, named after Hugo Schiff, are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by imine or azomethine group. They are widely used for industrial purposes and also have a broad range of applications as antioxidants. An overview of antioxidant applications of Schiff bases and their complexes is discussed in this review. A brief history of the synthesis and reactivity of Schiff bases and their complexes is presented. Factors of antioxidants are illustrated and discussed. Copyright © 2016 John Wiley & Sons, Ltd.

The Dynamics of a Tritrophic Leslie-Gower Food-Web System with the Effect of Fear

The avoidance strategy of prey to predation and the predation strategy for predators are important topics in evolutionary biology. Both prey and predators adjust their behaviors in order to obtain the maximal benefits and to raise their biomass for each. Therefore, this paper is aimed at studying the impact of prey’s fear and group defense against predation on the dynamics of the food-web model. Consequently, in this paper, a mathematical model that describes a tritrophic Leslie-Gower food-web system is formulated. Sokol-Howell type of function response is adapted to describe the predation process due to the prey’s group defensive capability. The effects of fear due to the predation process are considered in the first two levels

The Legal System of the Social Health Insurance in Egypt and its Impact on Iraq

Iraq issued the social Health Insurance Law No. 2 in 2020, thus taking its first step to introduce the universal health coverage. When the previous law was enacted, it was inspired by a number of countries, including the Arab Republic of Egypt, which began implementing the health insurance system since 2018, calling it universal health insurance and issued its law No. 2 of 2018, which was entitled as "The universal Health Insurance Law of the Arab Republic of Egypt". A national project at the all state level, such as the health insurance project, needs a set of equipment, both in terms of preparing the infrastructure or in terms of cooperation with health institutions in the public and private sectors, and both in terms of automating and

Modeling and Analysis of the Influence of Fear on a Harvested Food Web System

The food web is a crucial conceptual tool for understanding the dynamics of energy transfer in an ecosystem, as well as the feeding relationships among species within a community. It also reveals species interactions and community structure. As a result, an ecological food web system with two predators competing for prey while experiencing fear was developed and studied. The properties of the solution of the system were determined, and all potential equilibrium points were identified. The dynamic behavior in their immediate surroundings was examined both locally and globally. The system’s persistence demands were calculated, and all conceivable forms of local bifurcations were investigated. With the aid of MATLAB, a numerical simu

On The Queuing System M/Er/1/N

In this paper the queuing system (M/Er/1/N) has been considered in equilibrium. The method of stages introduced by Erlang has been used. The system of equations which governs the equilibrium probabilities of various stages has been given. For general N the probability of j stages of service are left in the system, has been introduced. And the probability for the empty system has been calculated in the explicit form.

Comparative study of the antioxidant effects of lavender and flax oils in recurrent aphthous ulceration treatment

Background: Recurrent aphthous ulceration (RAU) is an inflammatory condition of unknown etiology characterized by painful recurrent (single or multiple) ulcerations of the oral mucosa. It is one of the most common and poorly understood mucosal disorders. It occurs more frequently in times of stress. Local and systemic conditions, genetic, immunologic, microbial factors, and oxidative stress may play a role in the pathogenesis of RAU. The objective of this study was to evaluate the free radical metabolism and antioxidant activity of RAU patients treated by lavender or flax oil paint.

Materials and Methods: Sixty-six RAU patients were enroll
