Abstract
Introduction: Fertility regulation with plant preparations has been reported in ancient literature of indigenous systems of medicine. In this research the effects of alcoholic extract of Achillea millefolium flowers on fertility indices, body weight and weight of reproductive organs was evaluated in male rats.
Methods: 18 rats were randomly divided into 3 groups control, group A and group B, each group comprising of six rats. Animals in control group received 1 ml of distilled water(vehicle) and test groups(A and B) received graded doses of 200 and 400 mg/kg body weight of alcoholic extract of Achillea millefolium flowers on a daily basis for 50 days. At the end of 50 days of treatment period, fertility indices such as body and reproductive organs weight, sperm motility and count, fertility rate, epididymal sperm reserve(ESR), daily sperm production(DSP), blood testosterone concentration and fertility rate were measured.
Results: There was a significant decrease in GSI(Testes weight/body weight ratio), epididymides weight, sperm count, ESR, DSP, blood testosterone concentration and fertility rate in both the lower dose group (0, p<0.05, 0, 0, p<0.05, p<0.05, and 0) and the higher dose group(p<0.05, p<0.01, p<0.01, p<0.5, p<0.001, p<0.001 and p<0.05as compared to the control group.
Conclusion: The results of this study showed that alcoholic extract of Achillea millefolium flowers in higher doses could decrease fertility in male rats.

Abstract
Introduction: The aim of this study was to evaluate the relationship between metacognitive components and dysfunctional attitudes in outpatients with bipolar mood disorder II.
Methods: Thirty-six young adult outpatients with current diagnoses of BMD II(20 females and 16 males) were recruited from Esfahan Counseling Center. Diagnoses were based on the Structured Clinical Interview for DSM-IV Axis I Disorder-Clinical Version(SCID-CV). A battery of questionnaires including Metacognition Questionnaire and Dysfunctional Attitude Scale(DAS) were self-assessed by patients before medical therapy.
Results: Pearson's correlation analysis showed that the components of metacognition and its relationship with dysfunctional attitudes is positive and significant(r= 28/0, p<0/05). Multiple regression analysis showed that two of the metacognitive components emerged as potentially useful in prediction of dysfunctional attitudes(negative beliefs about uncontrollability, danger and thoughts control). Also, results indicated that those two components have a significant positive relationship with vulnerability, perfectionism and effectiveness)R²= 0/29, 0/35 p<0/05). Components of positive beliefs about worry and beliefs about cognitive self-consciousness related to cognitive confidence in predicting the criterion variable and its components showed no significant contribution.
Conclusion: Study findings suggest that DSM-IV BMD II outpatients with metacognitive distortions have shown higher levels of dysfunctional attitudes.

Abstract
Introduction: Additives such as nitrites compounds are used in meat products in order to create the desired color, creating the desired taste, prevent the growth of Clostridium botulinum spores and increase the storage time of the products. Today, due to the indiscriminate use of nitrogenous fertilizers, it is widely spread in water, soil and ecosystems, and the lives of many people could be put at risk. Therefore, this study was performed in order to examine the histopathological effect of sodium nitrite on Pulmonary artery in male rats.
Methods: This is a cross - sectional study in which 30 adult male and female rats strain Vistar were divided into 3 groups of 10 which involved 2 recipient groups who were given 175 mg/kg/day dose and 350 mg/kg/day dose of nitrite. The control group absorbed nitrite through drinking water. The 3 groups were examined for 60 days. At the end of day 60, after Anesthesia, the blood sample was collected from heart. The arteries were taking out of body, and then tissue sections were prepared for testing tissue changes. The samples were stained with HematoxilinEozin method and thickness of internal media (intima media thickness) was measured with Image tool software. Factors such as morphometric and morphologic from arteries, body weight changes were investigated before and after test and also blood nitric oxide level was checked. At the end, the obtained results were analyzed through spss 17 software by T-test and Anova test.
Results: The outcome of nitric oxide plasmatic density measurement showed that nitric oxide level in animal ’s blood in 175 mg/kg/day dose recipient group and 350 mg/kg/day dose recipient group increased significantly compared with the control group at the level of P ≤ 0.05. Also thickness of media layer decreased in maximum dose group (350 mg/kg/day dose) compared to the control group.
Conclusion: Based on the results of different doses of sodium nitrite, the nitric oxide levels in the blood were increased, and the thickness of middle layer of the lung arteries at dose 350 mg of sodium nitrite was reduced.

Abstract
Introduction: Cognitive performance in patients with schizophrenia and Bipolar I disorder seems to be different from the normal individuals, that these defects affect their treatment results. Therefore, this study aimed to compare executive function and behavioral inhibition within patients suffering from schizophrenia, bipolar type I as well as a normal group.
Methods: In this descriptive-comparative study, out of all patients hospitalized in daily psychiatric clinic in Najafabad in 2014 due to these disorders, 20 schizophrenia and 20 bipolar type I as well as 20 normal individuals were selected via the convinience sampling. All the study participants completed the computerizing tests including Tower of London and Go-No Go. The study data were analyzed utilizing SPSS software (ver 22) via MANOVA.
Results: The study findings revealed a significant difference between the two patient groups and the normal group in regard with executive function and behavioral inhibition (p<0.05), whereas no differences were detected between schizophrenics and bipolar patient groups. Furthermore, patients suffering from schizophrenia and bipolar I mood disorder demonstrated significantly poor performance in cognitive function and behavioral inhibition compared to the normal group.
Conclusion: The present study results can be significantly applied in pathology and therapy of these disorders, so as recognizing the inability of such patients can be effective in developing cognitive rehabilitation programs in these patients.

Abstract
Introduction: Physiological changes during pregnancy affect the teeth and tissues of the mouth and gums, which increases the severity of problems such as caries, inflammation, bleeding and swelling of the gum. Therefore, pregnant people need regular check-ups and provide adequate education. The aim of this study was evaluation of oral and dental health status in pregnant women referring to Fatemieh Hospital in Hamadan City during 2018.
Methods: This study was performed on 96 pregnant women. The adjusted questionnaire was completed for each individual by interview method in order to complete the section on personal and pregnancy data and examination in order to complete the section on oral and dental health status. Statistical analysis was performed using SPSS version 16 software.
Results: The mean age of the participants was 29.64. The Decay Missing Filling Teeth (DMFT) index in pregnant women was 10.48 ± 3.81. 75.74% of the participants were positive in terms of BOP. 12.50% had dry mouth. Using gingival index, 68.75% of the subjects had gingivitis and the mean gingival index was 0.98 ± 0.79%. In terms of oral hygiene, using the index plaque assessment, the majority of the participants was moderate (45.83%) and the mean plaque index was 1.27 ± 0.62%.
Conclusion: Pregnant mothers have a moderate oral health. For this reason, it is necessary to inform physicians in order to refer them to dentists and educate pregnant women to observe oral hygiene and prevent the occurrence of oral diseases and gingivitis in pregnancy.

Abstract
Introduction: Age-related macular degeneration (AMD) is one of the retina diseases in which retinal pigment epithelium cells are degraded and lead to blindness. Available treatments only slow down the progression of it. In this study, human embryonic stem cells (hESCs) differentiated into retinal pigment epithelium cells were cultured on a polycaprolactone scaffold.
Methods: The optimization of the diameter of the produced scaffolds by electrospinning method was done using the fuzzy method for the first time. To improve cell adhesion and proliferation, related parameters to alkaline hydrolysis method were optimized and hydrophobic surface of scaffold was modified. After in vitro analysis, cells were cultured on different groups of scaffolds. In vivo analyses were done and cells culture on scaffolds observed.
Results: The optimal parameters for the scaffold based on the fuzzy model were 18.1 kV for voltage, 0.07 g / ml for solution concentration and 115 nm for scaffold diameter, respectively. The immersion time of the scaffold in alkaline solution and concentration of solution were measured 97 min and 3.7 M, respectively. The treated scaffold had a higher degradation rate and water adsorption. MTT-Assay results showed that scaffolds with modified surfaces had a higher amount of cell viability and proliferation after 7 days. SEM image results confirmed this finding after almost two months. Additionally, the results of ICC test showed that after passing this time, cells kept their RPE and epithelium.
Conclusion: Based on the results, the hydrolyzed scaffold is a suitable substrate for cell proliferation and can be a good option for AMD treatment.

Abstract
Introduction: Odontomas are the most common odontogenic tumors. These lesions are usually considered a hamartoma than a neoplasm. Unlike normal tooth morphology, tissue arrangement is irregular in these lesions. Odontoma has self-limiting and slow growth, and if left untreated, its size will not increase over time. Most of these lesions are clinically asymptomatic and are detected on routine radiographs prepared for other purposes. Odontomas usually are located pericoronally and cause tooth eruption disorders such as the lack of permanent teeth or retention of deciduous teeth. In some cases, an odontoma can cause swelling and expansion of the jaw. The purpose of the current report is presenting an unusual complex odontoma in a 10-year-old boy, which was closely related to the roots of tooth #30. Odontomas are usually located pericoronally and near the roots of adjacent teeth, separated by a septum of bone. There are a few reported cases such as the current case, with fusion to the tooth structure. There was slight intraoral swelling and tenderness in the affected region. Unlike most reported cases, tooth eruption disturbance was not observed. Extreme proximity of odontoma and the roots of tooth were detected in Cone-beam Computed Tomography examination. Separative bone septum and the sharp outline of the tooth roots did not detected. The lesion and the related tooth were removed by surgical treatment, and the patient was followed for 2 years.

Abstract
Introduction: The problem of addiction potential experienced by young adults is usually accompanied by narcissistic personality traits. Research has confirmed two distinct forms of narcissism: grandiose and vulnerable. Meanwhile, shame as the main emotion and attachment style plays an essential role in these disorders. Therefore, the present study was conducted with the aim of reviewing research on addiction potential and the role of narcissistic factors, shame experiences, and attachment patterns. Using the Google Scholar database, key words such as Addiction Potential, Narcissism, Shame and Attachment Style were searched. PubMed was searched for Addiction, Narcissistic Personality Disorder, shame, and Attachment Styles. All time periods were used for this review and more than two hundred documents were reviewed and extracted based on the criteria.
Conclusion: The results showed that in some studies, a significant relationship was observed among potential for addiction, narcissism, shame experiences, and attachment patterns; in some other studies, potential for addiction was predictable through narcissism, shame experiences, and attachment patterns.
In general, we can conclude that addiction is a big problem that is affecting many societies today, by identifying how these factors are formed in children and development paths affecting it, a big step can be taken in the direction of educating parents and communities.
