Background: Oral squamous cell carcinoma represents the vast majority of oral cancer it is a common malignant tumor with an increasing incidence. Around the world, the 5 year mortality rate of oral cancer is about 50%. Thus novel biomarkers for early detection oral squamous cell carcinoma are needed. The level of three salivary microRNAs namely hsa-miR-200a, hsa-miR-125a and hsa- miR-93 were measured in saliva of patients with oral squamous cell carcinoma and compared their levels in saliva of healthy control subjects to determine their potential as oral cancer biomarker. Materials and methods: The level of these three microRNAs was measured by using revers transcription, preamplification and quantitative PCR. Results: Only miR-200a present in a significantly lower level (p<0.05) in the saliva of oral squamous cell carcinoma patients than in control. miR-200a was the strongest parameter (most affected by disease status) in the context of differentiation between OSSC and healthy controls (having the highest ROC area of 0.781 which is significantly higher than the area associated with equivocal test). Coming next in order of importance in the context of case-control differentiation was normalized CT values for hsa-miR-93, which has a reasonably high ROC (0.650), but failed to show statically significance differences, P>0.05. Conclusions: The detection of miRNAs in saliva can be used as noninvasive and rapid diagnostic tool for the diagnosis of oral cancer.
The aim of this novel native study was to determine the microbial contamination of broken and cracked imported commercial table egg in Baghdad markets and its economic effect. A total of 21510 commercial chicken table eggs were checked and surveyed from retail markets in different popular regions of Baghdad city during a year period from January 3rd to December 28th of 2018 and its microbial contamination were studied. Results revealed that significant differences (P<0.01) were appeared in the studied microbial counts during months of the study and significant differences (P<0.01) in the average counts between broken and cracked eggs and sound (not bro

That the issues and problems of the world today has become so large and complex that does not allow a specific field or knowledge to solve one of the need for the newly known knowledge integration (geopolitics and geopolitics) in particular to move towards cognitive integration to understand many of the problems and global issues that faced The importance of this study comes to clarify the relationship between Darwinism, geopolitics and geopolitics. The geopolitics in modern terms d

Humanitarian intervention has taken different forms included within the
peaceful and military means to stop the human suffering, whether caused by
natural disaster or humanitarian disasters.
Intervention can not be acquitted because it carries with it political cover,
but sometimes it may be legitimate cover for the occupation and the violation
of sovereignty. Therefore, the research worked to capture the legal and
political aspects of international law and the role of international organizations
to intervene and the right to use force.
The research concludes that international law had not been fairly
successful in controlling the behavior of some countries in the use of force,
and that there is

In this work, effects of using different evaporative cooling pads (ECPs) on the energetic and exergetic efficiency of a direct evaporative air cooler (DEAC) have been theoretically and experimentally investigated. Three types of ECPs were used, i.e., honeycomb cellulose cooler pad (HCCP), shading-cloth cooler pad (SCCP), and aspen wood wool cooler pad (AWWCP). For SCCP and AWWCP, a 3-cm pad thickness was used, while for the HCCP, three different values of pad thickness were used, i.e., 3, 5, and 7 cm. Tests were carried out using air velocities of 8, 14, and 19 m/s, measured at the DEAC outlet. Engineering equation solver (EES) used for performing the required calculations of the various parameters affecting the thermal performance of the D

This paper has been taken out of a PhD dissertation titled "features of the political of Ali Al-Wardi" by the student Nahid Jaber Hassan .It was supervised by assistant professor Dr. Amer Hassan Faiyadh. Ali Al-Wardi (1913-1995) is a brilliant Iraqi Scientist. He wrote many scientific books. He created so many en lighted societal thoughts. Concerning the political affairs, Al-wardi presented opinions concerning the Iraqi Society based on the tri-concepts (The individual to be a good citizen, the society to be civic and the state to be modern). This paper is concerned with the uncovering of the concepts of authority and the state in the thinking's of Ali alwardi .He considered those variables as the basis of the tri-dimensional political
