Background: The grading systems of salivary mucoepidermoid carcinoma depend on different histologic and morphologic features. The aim of this study was to compare between Auclair and Brandwein systems according to their histologic criteria, and the type of cell predominant. Materials and Methods: Twenty-one case included hematoxylin-eosin (H&E) stained tissue slides that were diagnosed as MEC, originally categorized into low and high grade type regardless of the grading system, have meticulously undergone histopathologic review. The sample was graded according to criteria owing to Auclair and Brandwein methods. The predominant type of cells was determined by microscopic examination according to grade of tumor. Results: Regarding the

Ex-situ bioremediation of 2,4-D herbicide-contaminated soil was studied using a slurry bioreactor operate at aerobic conditions. The performance of the slurry bioreactor was tested for three types of soil (sand, sandy loam and clay) contaminated with different concentration of 2,4-D, 200,300and500mg/kg soil. Sewage sludge was used as an inexpensive source of microorganisms which is available in large quantities in wastewater treatment plants. The results show that all biodegradation experiments demonstrated a significant decreases in 2,4-D concentration in the tested soils. The degradation efficiency in the slurry bioreactor decreases as the initial concentration of 2,4-D in the soils increases.A 100 % removal was achieved at initial con

Background: Pregnancy is a stressful state of increased inflammatory activity, and pregnancy – associated hormone changes can influence periodontal tissues, these inflammatory activity lead to production of inflammatory mediators. Interleukin 1 beta (IL-1β) is a potent pro-inflammatory cytokines that is consistently associated with periodontal diseases. This study was designed to determine the periodontal health status and detect the serum level of IL-1β in the healthy pregnant women at first, second and third trimester and compare it with healthy non pregnant women, and determine its correlation with different clinical periodontal parameters. M

The concept of the separation worry is considered one of the common disorders in children. The causes and effects of this worry influence the child mental and cognitive ability and the child ability to communicate with others, has friendship and the ability of adaptive with the environment, peers and teachers and it also influences the child's academic and social performance.
The importance of this study is represented in handling the working memory, one of important subject in cognitive psychology. Many universal studies show that the working memory is very important in several daily functions such as continuous attention, followinstructions, implement instructions of many steps, the moment of information remembering and keep focusin

Background: Fibromyalgia syndrome (FMS) is a very common cause of multiple regional musculoskeletal (MSK) pain and disability; it is characterized by chronic widespread for at least
three months and tender points identified by the American Collage of Rheumatology (ACR).The cause of FMS is currently unknown. However, several hypotheses have been developed including genetic predisposition. This study aims to evaluate the contribution of serum lipid profile to the pathophysiology of FMS.
Patients & Methods: The study has included 160 patients with FMS with age range (18-72) years and 60 control individuals who were age and sex matching with FMS patients: 29 patients with chronic musculoskeletal compla

Background: the activity of acute lymphoblastic leukemia had been observed to correlate with levels of serum lipoproteins

Objective: to evaluate the correlation of serum levels of different types of lipoproteins with activity of the disease in patients with acute lymphoblastic leukemia.

Type of the study: A prospective study.

Methods: A study included patients diagnosed as acute lymphoblastic leukemia, their serum levels of lipoproteins at time of diagnosis, and on relapse were obtained for comparison.

Results: there is significant inverse correlation of activity of acute lymphoblastic leukemia with serum total cholesterol

Background: Lung cancer is the leading cause of cancer deaths and its incidence is rising. The determination of histopathology and stage of primary lung carcinoma is crucial to develop appropriate treatment approach that affects morbidity and mortality. Fiber optic bronchoscope techniques for early detection of lung cancer are a promising tool as they might allow visualizing changes of early lung cancer and also permitting sampling for histological confirmation.
Objective: This study was intended to compare the fiber optic bronchoscopy findings and their anatomical locations with the histopathology types in patients with lung cancer.
Patient and Methods: A cross section study was conducted during the period

Background: Tympanometry findings are considered by many investigators to be associated with passive and active smoking.
Patients and methods: One hundred forty healthy adult men aged (20-50 years). 70 smokers and 70 nonsmokers were recruited for the study. The examination included otoscopy, and screening tympanometry. Smoking history was ascertained by self –report. For each subject, age, smoking status and number of cigarettes per day were noted.
Results: There is a tendency for more negative middle ear pressure in smokers than in non-smokers though this difference may not clinically significant. There were no significant differences in ear canal volume, middle ear compliance and presence of Staped

      It is common that extraterrestrial solar radiation R_a value lessen due to the interaction with atmosphere components to result a net solar radiation R_n value about one third of R_a for most measurements on earth. Net solar radiation had major impact on air temperature (T_o) value statement. So, its estimation is crucial for analyzing the interaction of (atmosphere-vegetation-soil).

Many methodologies available for this aim directly (with radiometer) or indirectly (with air temperature-based formula or soil plus air temperatures-based formula). The peak influences of global warming phenomenon were in eighties decade of the last century, yielding Iraq R_n rates to get cl
