Back ground: Zygote produce from once a sperm fertilizes an egg cell. Then, the zygote (unicellular) will begin chain of cellular cleavages to produce multicellular mass, its embryo, the differentiated to different tissues and organism. The development of the embryo is called embryogenesis. Coenzyme Q10, is an antioxidant produced in the body. It boosts cellular energy and may enhance the immune system. CoQ10 is present and measurable in seminal fluid, the concentration of CoQ10 directly correlates with both sperm count and motility. It is beneficial in the prevention and treatment a wide range of health problems. Objectives: The present study was aimed to investigate the possibility of using coenzyme Q10 to improve in vitro fertilization (IVF), and early embryonic development (ED) in mice as a model for human being . Materials and Methods: Superovulation program was achieved to mature healthy female mice with age 10-12 weeks and weight 24-26 gm. After sacrificing female, oocytes were collected and incubated within CO2 incubator for less than 1 hour. Sperm were collected from vas deference of males. Sperm parameters were assessed after 30 min. of incubation. Mature oocytes were divided into three groups according to the concentrations of CoQ10 including G1 (control group; SMART medium only), G2 (treated group; SMART medium enriched with 20 M CoQ10) and G3 (treated group; SMART medium enriched with 40 M CoQ10). IVF technique was performed for 3 groups, and assessment of IVF (%), embryonic development stage (%) and abnormal embryo morphology (%) for each embryo stage Results: Results of the present study appeared significant increment (P<0.05) in the percentages of IVF for both treated groups as compared to the control groups. Also, significant increase (P<0.0P) in the IVF (%) was observed when using 40 M CoQ10 as compared to 20 M CoQ10. Non significant differences (P>0.05%) in the 8-cells embryo stage were assessed among control and treated groups Conclusion: From the results of the present study it was concluded that the coenzyme Q10 (40µM) enriched to the culture medium improved percentage of in vitro fertilization and no effect on embryonic development.
The robot arm is the most popular robotic form used in industry. Thus, it is crucial to make a system programming which could controlled the movement of each part in the industrial robot to make it works properly. One of the simplest models of the robot arm is EDARM ED-7100 which has a controller to control the movement of the robot arm manually. In this study, the robot controller has been redesigned in order to improve this robot's function. The new controller system used AT89S52 microcontroller which has wire connected to the robot hand. A function has been added with this controller to improve the system of controlling and becomes better than the previous system (only manually). The functions of the new system include three mo

The present study tackles the complex issue of the urgent need for Environmental Auditing (EA) in Iraq in the absence of laws that support environmental management and in the light of the high rates of cancerous diseases in Iraq, which coincided significantly with the increase in oil production, according to the numbers indicated in the Iraqi Ministry of Health. The study aimed to investigate the mediating role of Management Systems (MS) related to the role of EA supporting sustainability reports concerning the reduction of the negative effects of gas emissions from oil companies. We adopted the descriptive approach which relies on studying relationships through a questionnaire that was distributed to a group of workers at Doura Refinery in
