Abstract
Abstract Background and objectives: Despite prenatal care, pre-eclampsia is still one of the most important causes of maternal and fetal mortality. There is no screening test for pre-eclampsia to be reliable and economical. One of the most accessible and easiest screening tests is blood uric acid measurement. The goal of this study is to assess the level of uric acid in high risk pregnant women a few weeks before emerging the manifestations of pre- eclampsia. Materials& Methods: In this study carried out in Isfahan medical centers, 124 pregnant women with gestational age of 24-28 weeks were selected by simple non-probability sampling. Then the subjects' uric acid were measured and considered high if it would be more than 4.5mg/dl. Results: of all the subjects, only 20 (16.1%) suffered from preeclampsia. 10 of 39(31.4%) who had high uric acid(more than 4.5mg/dl) showed pre-eclampsia.It is true for low uric acid women(68.6%), that is , the number of pre-eclampsia was ten. Conclusion: Relative risk of increased level of uric acid in preeclampsia at 24-28 weeks of gestational age was 2.2. Chi-square test showed that there is significant difference between the level of uric acid at 24-28 weeks of gestational age and the Incidence of preeclampsia. Keywords: pre-eclampsia, uric acid- high risk pregnancy

Abstract
ABSTRACT
Background and Objectives: Q fever is a zoonotic disease caused by an obligate gram-negative intracellular pathogen called Coxiella burnetii. The aim of this study was to determine the seroprevalence of anti-C. burnetii antibodies in bulk tank milk (BTM) samples of dairy cattle in west and northwest of Iran.
Methods: Overall, 71 BTM samples (covering nearly 700 dairy cattle) were collected in autumn 2013. A commercial Q fever antibody ELISA Test Kit (Liebefeld-Bern, Switzerland) was used to identify the presence of antibodies against inactivated phase 1 and phase 2 C. burnetii antigens.
Results: The results of ELISA test showed that 17 BTM samples (23.9%) were positive for the presence of anti-C. burnetii antibodies.
Conclusion: This study is the first to evaluate presence of anti-C. burnetii antibodies in BTM samples from dairy cattle herds in west and northwest of Iran. The high prevalence of this pathogen highlights the need for pasteurization of raw milk and raising awareness in consumers of dairy products in these regions.

Abstract
ABSTRACT
Background and Objectives: Acinetobacter species are responsible for a wide range of clinical complications in hospitalized patients. Antimicrobial treatment of clinical strains of Acinetobacter baumannii may be compromised due to multiple-drug resistance to b-lactams. Aim of this study was to determine antibiotic resistance patterns and frequency of PER and VEB genes in A. baumannii isolates from hospitalized patients.
Methods: In this cross-sectional study, 100 clinical strains of A. baumannii were isolated from patients hospitalized in Qom (Iran) using specific culture media and biochemical tests. The disk diffusion method was performed to determine resistance to some antibiotics. Minimum inhibitory concentration (MIC) for cefepime and ceftazidime was evaluated. Identification of ESBL-producing strains and presence of the PER and VEB genes were determined by combined disk test and polymerase chain reaction, respectively.
Results: The isolates were highly resistant against cefixime, ceftriaxone and cefepime. Lowest level of resistance was against polymyxin B. In addition, 70% of the isolates were multi-drug resistant. MIC<128 µg/ml to ceftazidime and cefepime was observed in 84% and 91% of the strains, respectively. Moreover, 21% of the strains were ESBL-positive and frequency of the PER and VEB genes was 47% and 32%, respectively.
Conclusion: Majority of A. baumannii isolates are highly resistant to the tested antibiotics. Due to presence of the PER and VEB genes in the isolated strains, there is the possibility of resistance spread to other bacteria. Therefore, it is recommended to modify the consumption pattern for antibiotics and pay more attention to standards of nosocomial infection control.

Abstract
Background: Omentin-1 plays an important role in insulin function. Despite numerous studies, the effect of interval training on this adipokine is still vague. This study aimed to elucidate the effect of high-intensity interval training (HIIT) on serum glucose, insulin, insulin resistance (IR), omentin-1 serum levels, and gene expression in the visceral adipose tissue in type 2 diabetic (T2D) rats.
Methods: In an experimental study, 20 male rats (8-10 weeks, weight: 250-270 g) were randomly divided into 2 groups: diabetic control (N=10) and diabetic training (N=10). The training protocol was 30 minutes of HIIT (1-min run, 2-min rest) performed 5 days a week for 4 weeks. Fasting blood glucose, insulin resistance, omentin-1 serum level, and gene expression were measured in the visceral fat 48 hours after the last exercise for both groups.
Results: The HIIT resulted in lower serum glucose and insulin resistance (P = 0.001), higher serum omentin-1 levels (P = 0.001), and higher visceral fat gene expression (P = 0.004) in the training group compared to the control group.
Conclusion: Lower serum glucose and insulin resistance and higher omentin-1 serum levels and gene expression in the training group can prove the effectiveness of HIIT training in T2D, although further research is required.

Abstract
Background: Exercise and dietary supplements can partially mitigate the negative effects of cadmium. The present study aimed to investigate the effect of swimming and silymarin on placental growth factor (PLGF) in pregnant mice exposed to cadmium.
Methods: Seventy-two 8-week-old pregnant Wistar rats (weighing 20 ± 200 g) were divided into 9 groups, with 8 rats in each group. Cadmium chloride at a dose of 400 mg/kg body weight was fed to rats by drinking a water solution. Silymarin (100 mg/kg body weight) was injected subcutaneously 3 times a week. The exercise program during pregnancy consisted of 60 minutes of swimming per day, conducted for 5 days a week. The microscopic sections of samples were taken 2 days after birth using the usual method of tissue sectioning. A 1-way analysis of variance (ANOVA) and Tukey post hoc test at the error level of 0.05 were used to analyze the data.
Results: The PLGF index in the cadmium group showed a significant decrease (P < 0.001) compared to the cadmium + silymarin and cadmium + silymarin and swimming groups. However, swimming training alone had no effect on PLGF index (P = 0.162).
Conclusion: Cadmium significantly reduced PLGF levels in neonatal lung tissue, and regular swimming endurance exercises and silymarin supplementation inhibited the effects of cadmium chloride.
