Abstract
Abstract Background and Objective: Ice cream is a suitable environment for microbial growth due to its chemical structure, ingredients, and its increased supply and demand. In the absence of hygienic considerations, it can cause poisoning. This study aimed to determine bacterial contamination in traditional ice cream produced in Arak city in 2011. Material and Methods: The samples (n= 30) were randomly obtained from different parts of Arak in, 2011. The Samples were shipped in cold conditions and total count of microorganisms test was performed according to Iranian national standards. Results: In 16.66%, the microbial contamination was below the limit of microbial load (5×104), and in 83.3% the contamination was more than allowed level. Conclusion: This study highlights the dire situation for bacterial contamination of traditional ice cream in Arak city. Keywords: Arak, Ice Cream, Microbial Contamination

Abstract
Background and Objective: The presence of microorganisms in food is a paramount importance to public health. This study was carried out to measure the rate of microbial contamination of the hamburgers consumed in Arak.
Material and Methods: The samples of frozen hamburgers ( n= 100) were collected from the selling centers in Arak. The city was divided into five areas and 20 samples were collecte from each area. The experiments of counting staphylococcus aureus with Iranian National No 6806-6, the total counting of bacteria No. 5272 and the counting mould and yeast with No 997 were carried out.
Results: the samples polluted by staphylococcus aureus were 26.6%. , 61.3% of the samples were higher than the required standard and 65% of the samples were higher than the required standard in Iran. The rate of staphylococcus aureus in the samples was 6×103 CFU/gr on average and the total counting of the bacteria was 5×106 CFU/gr on average, and the average rate of being polluted by fungi was 2×104 CFU/gr (820-36300) showing the high microbial contamination in this product. No significant difference was found at the level of different brands.
Conclusion: The results showed that 26.6% of the samples were contaminated with S. aureus, 61.3% with total microbial and 65% with fungal infection.

Abstract
Abstract
Background and Objective: Normal hemoglobin (Hb) is formed of a heme group and a protein group known as globin. Globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. Cellulose acetate method is a common way to differentiate haemoglobinopathies. Inability to identify the components of Hb low concentrations and incapability to isolate all Hb types are among the disadvantages of this method. The aim of this study was to report the prevalence of hemoglobinopathies in the North of Iran by capillary electrophoresis method.
Methods: All patients with suspected hemoglobinopathies, referred by physicians for electrophoresis, have been studied in a private center in the city of Gorgan, Iran. The level of HbA2, HbA, HbF and other Hb was recorded.
Results: Overall, 725 blood samples were analyzed using the capillary method. HbE was reported in 2 patients, HbH was observed in 2 patients and Hb Barts was reported in 3 patients. Using the capillary method, among patients with the SDG area, only 4 of 38 (10.52%) had HbS and the majority of them (89.48%) had HbD.
Conclusion: HbD is the most common hemoglobinopathy in the North of Iran.

Abstract
ABSTRACT
Background and Objective: It is desirable for athletes, especially female soccer players, to consume beetroot beverage during training as a way of improving both health and performance ,. Therefore, the objective of this study was to assess the effect of beetroot juice intake on lipid profile in female soccer players.
Methods: Young and well-trained female soccer players (N=20) were included in a randomized placebo-controlled crossover study. They were categorized into two groups: experimental (beetroot beverage, n=10, age: 23.20±0.91 years, BMI: 22.57±1.54(kg/m2)) and control (placebo, n=10, age: 23±0.81 years, BMI: 23.13±0.58(kg/m2)). Subjects drank either 200 ml concentrated beetroot beverage or an equal amount of placebo 2 hours prior to their trainings for six weeks (18 session). Blood samples were taken 24 hours before and after trials. All data were compared in pretest and posttest via paired sample t-test and independent sample t-test. All statistical analyses were performed at (P≤0.05) by SPSS (version22).
Results: Beetroot juice intake increased plasma high density lipoprotein (t= -60.88, P<0.05). Triglyceride, total cholesterol, and low density lipoprotein were reduced (P<0.05). Compared with placebo, beetroot juice reduced the concentrations of triglyceride, total cholesterol, and low density lipoprotein (P<0.05).
Conclusion: Regular beetroot juice intake has significant effects on lipid profile in female soccer players, hence its suggestion for preventing diseases such as hypercholesterolemia and hypertension in female soccer players.

Abstract
Background and objectives: As a chronic inflammatory airway disease, asthma can increase level of markers of inflammation and muscle damage. In this study, we aimed to evaluate the effects of short-term continuous aerobic exercise combined with vitamin D supplementation on high-sensitivity C-reactive protein (hs-CRP), lactate dehydrogenase (LDH) and creatine kinase (CK) levels in asthmatic women.
Methods: In this study, 30 overweight (body mass index=26.97± 1.24 kg/m2) women with mild to moderate asthma were purposefully selected.. The subjects received a vitamin D tablet with a daily dose of 1000 IU for six weeks. The training protocol consisted of two sessions of Balke treadmill test (one session before and one session after the vitamin D supplementation). Blood samples were taken before and immediately after the exercise and before and after vitamin D supplementation. Repeated measures ANOVA was used to evaluate changes in the levels of hs-CRP, CK and LDH.
Results: The variables were not significantly affected by the exercise and vitamin D supplementation (P>0.05).
Conclusion: It seems that a single session of short-term aerobic exercise and six weeks of vitamin D supplementation do not significantly affect hs-CRP, CK and LDH levels in asthmatic women.
