The current study was carried out on blood samples of 299 local breed female cattle in Erbil, Duhok and Suleimania, Northern Iraq, for the period from beginning of January till end of December 2006 for detection of piroplasmosis. By direct blood smear examination, the rate of Theileria annulata alone was 45. 1% while in mixed infections with Babesia was 11. 7%. The total rate of Theileria infection was 56. 9%. The haematological parameters of cattle infected with Theileria alone were PCV=27%, RBC= 5. 6 million/ cm3 and Hb 9. 5 g/liter did not vary from non infected ones. While in mixed infections (Theileria +Babesia) the blood picture values were decreased dramatically and were PCV=18%, RBC=4. 08 million/cm3 and Hb 5. 7 g/l. Using enzyme linked immunosorbent assay technique (ELISA), the seropositivity of Theileria was 77. 9%, while Babesia was 12. 4%. The overall rate of seropositivity by ELISA was 90. 3% for piroplasms while by blood smears examination the rate of infected animals was 56. 9%. From 5804 ticks collected from animal body, the constituencies of the ticks were 81. 7% H. anatolicum anatolicum, 15. 3% H. marginatum marginatum, 2. 82% Rhipecephalus appendiculatus and 10 ticks (0. 2%) were not identified. The highest rate of ticks was found attached to udder and under tail (77%), followed by ears (20%) and hind limbs and around eyes (3%). The distribution of ticks was highest in spring 96. 0%, followed by summer 4. 0%. No ticks were detected in winter and autumn. The greatest number of ticks was in March (37. 9%) followed by May (32. 23%), April (25. 85%), June (2. 17%), July (1. 68%) and August (0. 17%).

Background: Endometrial cancer is a common malignancy of the female genital tract. Her-2 overexpression is strongly correlated with tumor grade, type, and stage and this association complicate the issue of response of Her-2 positive endometrial carcinoma to chemotherapy. The aims of the current study are; to estimate the overexpression of Her-2 in endometrial carcinoma in our patients, to correlate the results with other known clinicopathologic markers and to compare our results with others. Material and Methods: This is a cross-sectional retrospective study of 51 cases of endometrial carcinoma collected with their clinical data from Al-Batool Teaching Hospital and Al-Khansaa Maternity Teaching Hospital in Mosul-Iraq from January 2007 to January 2010. All cases were revised histologically. Forty-three cases were total abdominal hysterectomy and 8 were curetting material. Tumors were classified into two main types, endometroid and non-endometroid carcinomas. Immunoperoxidase stains for Her-2/neu were performed on representative formalin-fixed paraffin embedded blocks. Results: Majority of the endometrial carcinoma were in the 6th decade (50.9%) with a mean of 56.5 year. Her-2/ neu overexpression was observed in 58.8% of cases. The most frequent association was with non-endometroid carcinoma (100%). Expression of Her-2/neu increased with increasing grade reaching 89.47% in grade III tumors. The highest expression was detected in tumors invading deep into the myometrium (77.77%). Conclusion: HER-2/neu appears to play an important role in the biologic behavior of endometrial cancers. It was overexpressed in non-endometroid carcinoma, especially papillary-serous type, high grade tumors, and among the higher stages. Therefore, targeted therapies directed against HER-2, could be effective in some patients with endometrial cancer. © 2013 DAR Publishers/University of Jordan. All Rights Reserved.

Experimental data are presented for a study on the dependence of the I-V characteristics of the corona discharge on pressure and electrode spacing using point-to-plane electrode configuration. These experimental data are obtained by a fast, automatic computer data-acquisition system. The data are used to suggest an alternative dimensionally self-consistent empirical equation for the parameterization of the I-V curves. The formula eliminates the need for any prior assumptions concerning the inception voltage, as is customary in this type of work.

'Golden Delicious' and 'Red Delicious' apple fruits were dipped in Aminoethoxyvinylglycine (ReTain®) solutions at the concentrations 0, 250, 500 and 1000 mg.L-1 for one minute and stored in a cool room at 0±1°C and 85-90% relative humidity for 3 or 6 months to study the effect of treatments on fruit storage characteristics. 'Golden Delicious' and 'Red Delicious' apples dipped in 500 or 1000 mg.l-1 AVG solutions maintained firmness and acidity, and the percent of superficial scald incidence was lower than that of untreated fruits. By 6 months fruit had softened, lost acidity and superficial scald incidence had increased, but to a lesser degree than in untreated fruit. AVG, especially at 1000 mg.L-1 decreased the development of fruit peel colour (carotene and anthocyanin), as well as decreased the rate of respiration of fruits after 6 months storage.

A total of 420, one day-old broiler chickens were randomly divided into 4 groups and kept under elevated summer temperature to investigate the effect of ascorbic acid and potassium chloride on the productive performance Live Body Weight (LBW), Body Weight Gain (BWG), Feed Consumption (FC), Feed Conversion Ratio (FCR), Mortality, Dressing Percentage (DP) and blood parameter (hemoglobin (Hb), Packet Cell Value (PCV), Red Blood Cell (RBCs), pH and serum glucose) and rectum temperature. Heat stress was associated with an increase in FCR and mortality and a decreased LBW, BWG and FC of birds. Ascorbic acid and potassium chloride supplementation during heat stress had a beneficial effect on LBW, BWG, FC, FCR, DP, mortality, pH, Serum Glucose and rectum temperature. © Asian Network for Scientific Information, 2011.
