Abstract
Background: Brucellosis is one of the most common zoonotic diseases in Iran. In most cases, the diagnosis of brucellosis is difficult not only because of its clinical similarity to many infectious and noninfectious diseases, but also because diagnostic methods often fail to detect organisms. PCR is a rapid and safe diagnostic method applied to the diagnosis of brucellosis. The purpose of this study was to determine the sensitivity and specificity of PCR for diagnosis of human brucellosis by using serum samples. Materials and Methods: This study which was done to evaluate diagnostic tests included30 serum samples from patients with clinical presentation of brucellosis with positive Wright test and serum samples of30 healthy people with negative Wright test. These samples were examined by PCR. Results: PCR results were positive for 15 samples of the patients group in comparison with 4 samples from the 30 healthy subjects. The sensitivity and specificity of PCR were 50% and 86.6%, respectively. Conclusion: Although in some studies, the preferred sample for diagnosis of brucellosis was serum, in this study, PCR on serum samples did not indicate high sensitivity and specificity in diagnosis of brucellosis. Hence, using a combination of methods for diagnosis of human brucellosisis suggested.

Abstract
Background: Chronic kidney disease as an important risk factor is associated with some disorders which are key causes of death and disability in older people. Therefore, the aim of this study was to assess the combined effect of regular aerobic exercise with garlic extract on renal apoptosis regulatory factors in aged rats with chronic kidney disease.
Materials and Methods: In this experimental research, 42 aged male Wistar rats(48-52 weeks) were selected and randomly divided into 6 groups: control, doxorubicin, doxorubicin-salin, doxorubicin- garlic, doxorubicin - exercise, doxorubicin –garlic-exercise(combined). Chronic kidney disease was induced by a single subcutaneous injection 8.5 mg/kg of doxorubicin. Swimming training was programmed 3 days /week, 30 min/day for 8 weeks. Both the doxorubicin garlic and combined groups with garlic extract were administered by garlic gavage at a dose of 2.5 g/kg. The renal Bax and Bcl-2 levels were evaluated by ELIZA method. A one-way analysis of variance was used to data analysis (p<0.05).
Results: The results showed that induced chronic kidney disease was associated with a significant increase on Bax and a decrease on Bcl-2 in aged rats. Also, 8 weeks swimming training, garlic supplementation and the combined intervention significantly reversed these changes. Furthermore, no significant difference have been observed in the effect of these interventions on Bax and Bcl-2 in aged rats with chronic kidney disease.
Conclusion: It seems that the use of non-pharmacological treatment methods such as exercise training, garlic extract supplement, and combination of the both interventions may be effective in reducing apoptosis resulted from chronic kidney disease in aged rats.

Abstract
Background: Tympanometry is one of the most important audiological tests for the assessment of neonatal hearing screening programs. This test is usually done using a 226 Hertz probe tone; however, in infants less than 6 months of age, using this probe tone frequency is not reliable due to the different characteristics of the middle ear compared to adults. The purpose of this study was to assess the obtained tympanometric data in neonates 1 to 14 days with normal hearing using 226, 678, 800 and 1000 Hertz frequency probes tones.
Materials and Methods: In this cross-sectional study, 30 neonates aged 1 to 14 days who were diagnosed as normal in hearing aspect with using otoacoustic emissions test, were assessed by tympanometry. Tympanometric tests were performed using 226, 678, 800 and 1000 Hertz frequency probe tones for both ears. For data analysis, the T-paired method has been used.
Results: With using 226 Hertz frequency probe tone, incidence of unusual double peak tympanograms was observed in 65% of cases, which with increasing frequency of the probe tone, this percentage was decreased. There was also a statistically significant difference between the static admittance peak compensated in two 226 and 1000 Hertz frequency probes tones.
Conclusion: In neonates with normal hearing and without any risk factors for hearing loss, the 1000-Hertz Tympanogram shows a better middle ear status than the 226-Hertz tympanogram.

Abstract
Background: Today, the high prevalence of diabetes and its complications are one of the most important public health issues worldwide. For this reason, finding relations between diabetes risk factors is very effective in preventing and reducing complications. For discovering these relations, the data mining methods can be used. By extracting association rules, which is one of the data mining techniques, we can discover the relations between a large numbers of variables in a disease.
Materials and Methods: The population of this study was 1046 patients with type 2 diabetes, whose data had recorded between 2011 and 2014 at the Special Clinic for Diabetes in Tehran's Imam Khomeini Hospital. After pre-processing step with SPSS19 software, 573 people entered the analysis phase. The FP-Growth algorithm was applied to the data set to discover the relations between heart attack and other risk factors using Rapid miner5 software. Relations, after extraction, were given to the doctor to confirm clinical validation.
Results: The obtained results of studying these 573 people (Including 292 (51%) women and 281 (49%) men, with age range 27 to 82 years) showed that the lack of blood pressure, creatinine and diastolic blood pressure at its normal level, despite higher systolic blood pressure level than normal, doesn't increase the probability of heart attack.
Conclusion: Using association rules is a good way of identifying relations between the risk factors of a disease. Also, it can provide new hypotheses to do epidemiological studies for researchers.

Abstract
Background and Aim: In this study, the effect of Myrtus extracts on 25 methicillin resistant Staphylococcus aureus (MRSA) and Escherichia coli ESBL strains isolated from patients were compared by two methods.
Materials and Methods: 15 methicillin-resistant Staphylococcus aureus (MRSA) and 10 Escherichia coli ESBL isolates were used in this study. Fresh Leaves of Myrtus were collected from the herbal medicine farm. Extraction was performed using a reflux distillation. The effect of concentrations 0.195-100 micrograms per ml of Myrtus extract on clinical isolates was analyzed in disk diffusion method compared with micro broth dilution method and with MTT in 545 nm on an ELISA reader apparatus.
Findings: Inhibition zone diameter for the minimum effective concentration of 50 micrograms per milliliter in all isolates of ESBL and MRSA were as 8±1 mm and 11±1. Minimum Inhibitory Concentration (MIC) was 6.25mic/ml and Minimum Bactericidal Concentration (MBC) was determined 12.5mic/ml for E. coli ESBL. Furthermore, the amounts for MIC and MBC was determined as 12.5 and 25 mic/ml, respectively for Staphylococcus aureus.
Conclusion: The results of this study showed compliance of two methods in evaluation of drug-resistant clinical isolates. It was proved that the disk diffusion method could be determining range of effective concentration but micro broth method determines the effective concentration carefully. It is recommended that results obtained from disk diffusion not to be basis for final decisions in traditional medicine studies. Bacterial behavior in the broth and determination of the point of death greatly increases the accuracy of the results.
