Incidence of Canine Digestive System Tumours in Baghdad Province
...Show More Authors

Tumours in pets occur naturally and are common in dogs as they are in humans. Tumours of the alimentary system have been reported in animals, although less frequently. Food patterns and specific diet components could have a big role in such tumour occurrence. Therefore, the aim of this study was to investigate the clinical signs and inspect the neoplasm lesions of the gastrointestinal (GI) tract grossly and histopathologically in dogs in Baghdad, Iraq, and to see whether pet diets had any tumourigenic effect. Throughout two years sixteen dogs were referred to Teaching Animal Hospital and private clinics at Baghdad city with masses in (GI) tract. Males and large size breeds were more likely to be affected with GI tumours. Half of the cases aged 5-10 years and belonged to German Shepherd, while the other half involved the other breeds (i.e. Belgian Malinois, Labrador, Pointer GSP and Terrier) equally. Biopsies were taken from the tumour tissues for histological examination. Clinically, the animals presented general signs of digestive system abnormalities, like difficult defecating, bloody stool, lethargy and weight loss. Grossly, the tumours varied in their sizes from <3 cm to >5 cm in diameter, and the most frequent site of occurrence (10 out of 16 cases) was in the large intestine. Histologically, most tumours reported were malignant, and included adenocarcinomas (6/16) followed by leiomyosarcoma (4/16), adding to 2/16 belonged to carcinoid tumour. However, lipoma and viral papilloma (4/16) were also registered as benign tumours. In conclusion, tumours of canine digestive system do exist but rare. Healthy nutrition of dogs may prevent this type of cancer by consuming enough amount of raw meat, little artificial food, e.g. kibble along with some vegetables and fruits. Additionally, the information gained from dogs could be used to suspect and test the effect on humans as they have strong pathophysiology similarities.

...Show More Authors

   A histological study was conducted to examine the structure of rhombencephalon (Cerebellum) in Columba livia gaddi (Gmeiin, 1789).  The result showed that the cerebellum is aportion of the brain lying behind the cerebrum, the surface of the cerebellum contains deep folds.  The cerebellum consists of two regions a cerebellar cortex that is called gray matter composed of three major layers from the outside to the inside, as follows: molecular layer, Purkinje cells layer and granular layer, the second region of cerebellum called medulla. This is the white matter.

Role of Extracted Genomic DNA on Biofilm Formation by Pseudomonas aeruginosa and Klebsiella pneumoniae in vitro
...Show More Authors

   Bacteria form complex and highly elaborate surface adherent communities known as biofilms.Biofilm have been shown to be associated with several human diseases ,and to colonize a wide variety of medical devices . The current study focuses on contribution of extracted genomic   DNA in  biofilm formation by   P. aeruginosa and  K. pneumoniae isolates   .The percentages of Pseudomonas aeruginosa recovery from drinking water  in this study were  10%(20 positive P. aeruginosa  samples ) and K. pneumonia.,  7%(14 positive K. pneumonia samples).The results showed that all P.aeruginosa and K. pneumoniae isolates (100%) were slime producer but in different degrees by forming  of black

Relationship Between Lipid Peroxidation and Vitamine (E) ,  -Tocooherol Supplementation in Sera of Apparntly Healthy Individuals
...Show More Authors

  In an attempt to shed a light on the possible relationship between lipid peroxidation and some antioxidant.         The effect of vitamine E (as a potent antioxidant free radical scavenger) on the serum levels of Total cholesterol (TC) and Triacylglycerols (TG) was studied and the lipid peroxidation marker (MDA) was measured.       The study includes (50) healthy donors from males and females who had given vitamine E at a rate of (400IU) daily for one month and were divided into two groups. 1. Group (A) : included (25) males donors (20-40) years old, before and after giving vitamine E. 2. Group (B) : included (25) females donors (20-40) years old , before and af

Problems lead to the low level of academic achievement in the evening school: suggestions and solutions
...Show More Authors

Academic achievement is a professional standard for measuring student levels in the first stages. Therefore, any indication of the level of achievement makes us in an attempt to employ students in evening schools. The researcher has developed a closed questionnaire of (36) paragraphs. A total of (164) male and (24) female students were chosen from evening schools. The result of this research revealed that the number of students was a reason for the low level of their achievement, the lack of laboratories, educational methods, and techniques of the most prominent problems confirmed by students in these schools. In addition, to support educational institutions with their necessary needs. The most important conclusion in this research is th

Analysis of Temperature and Residual Stress Distribution in CO2 Laser Welded Aluminum 6061 Plates Using FEM
...Show More Authors

This paper develops a nonlinear transient three-dimensional heat transfer finite element model and a rate independent three-dimensional deformation model, developed for the CO2 laser welding simulations in Al-6061-T6 alloy. Simulations are performed using an indirect coupled thermal-structural method for the process of welding. Temperature-dependent thermal properties of Al-6061-T6, effect of latent heat of fusion, and the convective and radiative boundary conditions are included in the model. The heat input to the model is assumed to be a Gaussian heat source. The finite element code ANSYS12, along with a few FORTRAN subroutines, are employed to obtain the numerical results. The benefit of the proposed methodology is that it

Levels of Serum Lipid profile and Kidney Function Tests in Iraqi Hypertensive Patients: Duration Effect Study
...Show More Authors

Hypertension is one of the leading causes of the global burden of disease, which causes serious health problems. The aim of this study is to investigate the lipid profile levels in sera of Iraqi hypertensive patients by measuring Total cholesterol (TC), triglyceride (TG) and low density lipoproteins (LDL) and kidney function levels by measuring uric acid, urea and creatinine. Seventy five individuals of Iraqi adults (Males) were divided into three groups: 25 hypertensive patients with duration of disease (1-10) year (group 1), 25 hypertensive patients with duration of disease (11-30) year (group 2) and 25 normal individuals as control group (group3). The findings indicate that serum (TC, TG and LDL) levels were significantly elevated (

Studying the properties of linearly polarized modes in step index optical fibers at 1030 nm wavelength
...Show More Authors
Abstract<p>The growing demand for optical fibers is due to their superior the ability to transmit information with high efficiency and minimal loss across extensive distances. In this study, four optical fibers with core radii ranging from (2.05-5.05) μm, and with a numerical aperture of 0.1624 were analyzed. The modal properties of these fibers were calculated at a wavelength of 1030 nm using the RP Fiber Calculator software (free version 2025). Furthermore, the impact of increasing the core radius on these properties was examined. The results showed that multimode fibers are formed when the core radius is much larger than the wavelength used. In contrast, single-mode fiber is obtained when th</p> ... Show More
