Abstract
Background: The role of sex hormones in pain perception and the effect of stress on reproductive system have not been determined yet. The present study investigated the effects of acute and chronic restraint stress on nociception and sex hormones concentration in rats. Methods and Materials: This experimental study was carried out with 47 male and female rats which ranged in weight from 170-230 gr. In order to transmit stress to the rats, they were initially exposed to acute restraint stress (1h) and chronic stress (for two weeks-1h/day). Then they were submitted to tail flick test for nociception evaluation. Sex hormones serum level was measured by radioimmunoassay method. Results were analyzed with Mann-Whitney and Kruskal-Wallis tests. Results: In male and female rats, acute restraint stress had significant increment in latency in the tail flick test. Chronically stress in male rats, was not significant effect on latency time. Chronically stress in females responded to restraint stress with an increase in tail flick latency. Both acute and chronic restraint stress reduced testosterone level in the male rats. In the female rats, only acute restraint stress significantly decrease plasma estradiol level. Restraint stress did not effect on testosterone concentration level in the female and estradiol level in the male rats. Conclusion: Acute restrain stress decrease nociceptive and sex hormon levels in male and female rate but, chronic restraint stress causes sex dependent response.

Abstract
Background: Psoriasis is a common chronic skin disease which usually appears as white and silvery spots on the skin. The purpose of this study is to investigate the effect of berberine on patients with psoriasis. Materials and Methods: This double-blind clinical trial was conducted on 60 psoriasis patients who referred to Imam Khomeini Hospital, Ahvaz, between July and December 2011. The patients were randomly divided into two equal groups that applied berberine and placebo to the treatment of their lesions twice a day. Lesions severity rate in the patients was assessed 7 times using a Psoriasis Area Severity Index (PASI). Data were analyzed by ANOVA with repeated measurements and Chi-square using SPSS software. Results: After 6 months, severity of lesions showed a significant decrease in the group receiving the berberine cream compared with the placebo group so that the mean PASI score of the group receiving berberine decreased from 3.99 to 2.11 while in the placebo group this decreased from 3.98 to 3.71. Mean difference in PASI score was not significant before receiving the treatment till the third month in berberine and placebo groups, but in the fourth to sixth months it was statistically significant (p=0.013). Conclusion: Berberine cream was more effective than the placebo in reduction of skin lesions of psoriasis patients. Therefore, it is recommended that plant-based drugs, like berberine, be used more besides the main medications of patients.

Abstract
Background: Depression is one of the most commonly observed problems in menopausal women. This study was conducted to determine the effect of omega-3 fatty acids on menopausal depression in women referring to No. 1 Health Clinic of Ahvaz, Iran, in 2010.
Materials and Methods: This randomized double-blind clinical trial was done on 70 menopausal women experiencing various levels of depression. After administering the Hamilton Depression Rating Scale (HAM-D-21), the participants who met the inclusion criteria were randomly divided into intervention group (n=35) receiving a 2gr omega-3 capsules and control group (n=35) receiving 2 gr placebo capsules. After 8 weeks of intervention, data were collected and analyzed by Chi-square, independent t-test, and one-way ANOVA with repeated measures using SPSS software version 17.
Results: Mean depression scores decreased significantly (p<0.001) in the intervention group (13.36±2.23 to 8.72±3.71). Also, mean depression scores decreased (p>0.05) in the control group (13.25±2.04 to 11.78±2.93) however, it was not significant. The comparison of depression scores did not indicate a significant difference regarding the reduction of depression after intervention between the two groups (p=0.08).
Conclusion: According to the findings of this study, administration of omega-3 capsules (2gr/daily) for 8 weeks decreased menopausal depression. However, there was not a significant difference between omga-3 and placebo groups in this study. For a more precise observation of the effects, further studies with longer periods of intervention are needed.

Abstract
Background: Selenium is a unique trace element which is benefit on inflammatory underlining diseases. MAPK (Mitogen-activated protein kinase) pathways regulate several cellular functions including inflammation, cell differentiation, migration, and apoptosis. Objective: This study aimed to find out the pathway(s) by which Selenium modifies inflammatory events in oxidative or thrombotic induced stress in platelet.
Materials and Methods: This is a basic -experimental study on Human platelets obtained from 30 healthy individuals (age 35±12) .The phosphorylation rate of P38MAPK , c –JNK (c-Jun N-terminal Kinase), and ERK1/2(Extracellular signal-regulated kinases1/2) as three important proteins in MAPK family and P-selectin were measured in presence or absence of selenium by ELISA( solid phase sandwich Enzyme Linked-ImmunoSorbent Assay). Pharmacological inhibition is done by inhibitors of P38MAPK, ERK1/2 and c- JNK in order to compare with selenium effects. The percentage of ratio of phosphorylated to total protein was used for normalizing the phospho protein contents of platelets.
Results: Selenium significantly reduced P-selectin expression (p<0.05), P38MAPK (p<0.05) and c- JNK phosphorylation (p<0.05) induced by cu2+oxidized LDL in platelets but Se couldn’t significantly reduce Thrombin induced P-selectin despite of decreasing in mentioned phospho-proeins.
Conclusion: Our results indicated that Selenium can reduce inflammation via suppression of p38MAPK-dependent signaling pathway. These results may provide insights related to development of novel Selenium therapies in atherosclerosis.

Abstract
Background: Inflammation plays an important role in the pathogenesis of atherosclerosis and change in lifestyle represents a successful strategy to prevent cardiovascular disease. Therefore, the present study investigated the combined effects of regulae Pilates training and Apium Graveolens seed supplement on monocyte chemoattractant protein-1(MCP-1) and C-reactive protein (CRP) in sedentary women.
Materials and Methods: In this quasi-experimental study, 28 healthy sedentary woman with age average 31±5.5 years old are selected in a convenience sampling way and randomely divided into and control, exercise, supplement and exercise+supplement groups. Pilates exercise was consisted of exercise movements at 50% to 80% maximal heart rate in, 3 sessions per week for 8 weeks. Supplement and exercise+supplement groups consumed 1.3 gr Apium Graveolens seed capsule three times a day after meals. Fasting blood samples were collected before and 48 hours after the last interventions. MCP-1 and CRP levels were measured by ELISA method.
Results: Eight weeks of Pilates exercise, supplementation and the combined intervention were associated with a significant increase in MCP-1 and CRP levels (p<0.05). Furthermore Pilates exercise and combined intervention were associated with significantly greater increases in percent changes of the MCP-1 and CRP compared to supplement group (p<0.05).
Conclusion: These findings suggest that the protective effect of Pilates exercise and Apium Graveolens seed supplementation non-drug interventions might in part be due to suppression of the inflammatory processes.

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: Candida albicans is still the main etiologic agent of candidiasis. However, infections of non-albicans Candida species are increasing. Candida dubliniensis is similar to C. albicans phenotypically and must be identified due to the better management of infection. The aim of the present study is to defferentiate and identify Candida species by Duplex PCR for getting an epidemiological data of Candida species among clinical specimens.
Materials and Methods: DNA was extracted using phenol-chloroform method from fresh colonies. Internal Transcribed Spacer region was amplified by polymerase chain reaction using specific primers. Based on differences of bands sizes on agarose gel electrophoresis, species were identified.
Results: Ninety four out of 100 patients (49 males and 51 females) had predisposing factors in the present study. Diabetes (73.4%), use of antibiotic (6.3%), vitamin deficiency (4.3%) were the main predisposing factors. The most specimens belonged to mouth (75%), vagina (5%), and blood (4%). All isolates were identified as C. albicans.
Conclusion: Duplex PCR is a rapid and precise method for the detection and differentiation of Candida species carefully, and in this method, phenotypic tests like germ-tube and chlamydoconidia production, as well as biochemical tests are not required for clinical laboratories that have limited resources and time for response to the patients, and it can replace with the traditional methods.

Abstract
Background: Nanoparticles are used in various applications due to unique mechanical and physicochemical properties such as their increased surface area to volume ratio and quantum effects. This study was designed to investigate the cytotoxic effects of zinc oxide nanopaticles on hematological and biochemical parameters BALB/c mice.
Materials and Methods: In this experimental study, 28 adult male mice BALB/c, were divided into four groups (one control group and three experimental groups). The mice in the experimental groups orally received Zinc Oxide nanoparticles with doses of 50, 100 and 300 mg/kg for 14 days. The control group received distillated water only. On 15th day, some hematological and biochemical parameters were studied on the blood samples collected.
Results: Results showed that Zinc Oxide nanoparticles cause changes in blood cells. In high concentration, nanoparticles increased some of factors such as white blood cells, hemoglubin, MCV and neutrophil and besides decreased amount of RBCs, pLTs, hematocrit, lymphocytes, glucose and kratenin significantly (p<0.05).
Conclusion: The findings showed that zinc oxide nanoparticles cause harmful effects due to the considerable variations in hematological and serum parameters in mice in a dose-dependent way.

Abstract
Background: Fetal hemoglobin (α2γ2) is the main oxygen transport protein in the human fetus. Fetal hemoglobin is nearly completely replaced by hemoglobin A, except in a few thalassemia cases and sickle cell anemia. Several studies have indicated that expression of γ-globin might be regulated post-transcriptionally. Small non-coding RNA called microRNAs which target mRNA can lead to translated repression or mRNA decay. The aim of this study is to investigate the effect of miR-940 up-regultion on γ-chain gene expression and erythroid markers in k562 cell line.
Materials and Methods: In this experimental study, k562 cells were cultured in RPMI1640. Then pre miR-940 was transfected by electroporation method in k562 cell line. In 3, 7 and 14 days, RNA was extracted and cDNA synthesized in selected days. Up-regulation of miR-940 was confirmed by miRNA Quantitative real time PCR and then the expression γ of chains and GATA-1 was investigated by QRT-PCR. Finally, erythroid markers were checked by flow cytometry.
Results: In 3, 7 and 14 days after transfection, the GATA-1 and γ-chain expression were increased in comparison with untransfected cells. Also, the expression of erythroid markers was increased.
Conclusion: The data show that up-regulation of miR-940 has a role in the increase of γ-chain gene expression in k-562 cell line. We suggest that miR-940 may be a significant potent therapeutic target for increasing Hb F level. Patients with sickle cell anemia and β-thalassemia are suitable candidate for treatment in this way.

Abstract
Background: Ovarian cancer is one of the common malignancies within gynecological cancers. Its lethality may be due to problems in distinguishing it at an early stage and lack of effective managements for patients with a progressive or recurrent status. Therefore, there is an essential need for prognostic biomarkers to diagnose or identifying mechanism of disease for effective treatment. It has been found out that, TRAF4 gene was significantly transformed in different cancers. Therefore, the aim of the present study was to investigate the TRAF4 gene expression in ovarian cancer.
Materials and Methods: In this study, 40 formalin fixed paraffin embedded tumoral tissues of ovarian cancer and 40 non-tumoral tissues were enrolled. Afterwards total RNA extraction and cDNA was synthesized, the relative gene expression was determined using quantitative real-time PCR (qRT-PCR) and evaluated by 2-∆∆ct method. Finally, the expression pattern was analyzed by statistical analysis.
Results: The results of recent study showed that TRAF4 expression was significantly increased in tumoral samples (p=0.0001). According to the study of demographic and clinopathology information with gene expression, there was seen a significant relationship between metastasis and up-regulation of gene. Also, there was a higher expression in TRAF4 gene in patient’s ≤ 48 years old.
Conclusion: According to different studies, it seems that TRAF4 over expression is likely due to amplification of gene copies in chromosomal zone in cancers. Considering the results of present study and the over expression of TRAF4 in ovarian cancer specimen, especially over expression in patients≤48 years old, TRAF4 gene can be considered as a diagnostic biomarker.

Abstract
Introduction: One of the problems during adolescence is the existence of conflict with parents, which creates object relationships and feelings of shame and guilt in them. This research was conducted to determine the effectiveness of treatment based on the mentalization of object relations and feelings of shame and guilt in conflicting mother-child relationships.
Methods: This research method was semi-experimental and pre-test-post-test with a control group. The statistical population of this research included all mothers and adolescents with conflicting relationships who were referred to counseling centers in Shiraz in 2022. By using the available sampling method, 30 people from the mentioned community were selected as a sample and were randomly divided into two experimental (15 people) and control (15 people) groups. Asadi et al.'s parent-child conflict questionnaires (2010), Bell's object relations (1995), and Cohen et al.'s (2011) feelings of shame and guilt were used to collect information. The experimental group underwent executive function training for 13 sessions twice a week for 60 minutes, and the control group did not receive any training. The research data was analyzed using correlation.
Results: The mean ± standard deviation of the experimental group in the post-test in the variable of object relations from 1.5 ± 1.37 to 28.6 ± 4.3 and in the variable of shame and guilt from 5 ± 1.60 to 5.60 ± 3. 51.2 ± 9.1 decreased. The results showed that in the post-test stage, the mean scores of object relations and feelings of shame and guilt in the experimental group decreased significantly compared to the control group (P < 0.01).
Conclusions: Treatment based on mentalization was effective in improving object relationships and reducing feelings of shame and guilt. Therefore, this treatment can be suggested to reduce the conflict between adolescents and mothers.
