Background: Bipolar disorder is a disabling illness characterized by recurrent episodes of mania, hypomania, and depression. The dialectical behaviour therapy (DBT) is basically designed to help regulate excitement, tolerance of discomfort, mindfulness and interpersonal relationships. This study aimed to determine the effectiveness of DBT on executive function, emotional control and symptom relief in patients with type 1 bipolar disorder. Materials and Methods: This clinical trial was conducted on 50 patients with type 1 bipolar disorder. These patients were divided into two 25 populated groups of controls and intervention. The control group did not receive any other alternative therapy apart from routine medications, but in the intervention group, in addition to routine medications, DBT treatment was also done as complementary therapy in 12 sessions based on Dick's protocol. Then, Mania severity, emotional control and their executive functions were evaluated before and after the intervention and compared in two groups. Results: After the intervention, the scores of mania and depression mood with the mean of 2.12 ± 3.09 and 31.08 ± 8.98 respectively in intervention group were significantly lower than control group with the mean of 4.24 ± 4.11 and 39.92 ± 9.05 respectively (P < 0.05). Depression and executive function of the patients had no significant difference between the two groups in the post-intervention period and had a modest and non-significant change. Conclusion: DBT has been effective in decreasing the intensity of mania, but, it cannot be used to reduce the emotional instability and impulsivity of these patients along with drug therapy although it has improved the executive functions and depression of the patients.

Background: The development of protective vaccines for Brucella spp. has been hampered by the difficulty in transformation of Brucella cells with foreign DNA for genetic manipulation. It seems that the formation of Brucella spheroplasts would increase the efficiency of transformation. The aim of this study was to devise an efficient method for the transformation of Brucella spp. Materials and Methods: At first, spheroplast of Brucella was prepared by glycine and ampicillin induction and transformed using optimized protocols of CaCl², electroporation, and lipofection methods. Then, the efficacy of transformation was compared between the three-mentioned methods. Results: Ampicillin-induced spheroplasts from early-log phase culture of brucella when incubated in a medium-containing 0.2 M sucrose during cell recovery had higher transformation efficiency in three different methods. Comparison of the transformation efficiency of Brucella abortus RB51 using the CaCl2, lipofection, and electroporation methods revealed that the transformation efficiency with the lipofection method was significantly higher than with other two methods (P < 0.05). Conclusions: Lipofection method by lipofectamine 2000 on ampicillin-induced spheroplasts can be a suitable approach for Brucella transformation.

Background: Hydatid cyst is a zoonotic and parasitic disease with worldwide distribution. Anticancer effects of hydatid cyst have been shown in cell culture experiments and animal model investigations. The mechanism of anti-cancer effects of hydatid cyst fluid has not been clearly elucidated, and the induction of apoptosis may have a role in this regard. Hence, in this study, the effect of hydatid cyst fluid (HCF) on the induction of apoptosis on mouse breast cancer (4T1) cell line in cell culture medium has been investigated. Materials and Methods: Echinococcus granulosus HCF antigens including Antigen B (AgB), glycolipid, glycoprotein, and 78 KDa fractions were prepared. Breast cancer cell line (4T1) was cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum and appropriate antibiotics. Apoptosis was determined by flow cytometry using the annexin V-fluorescein isothiocyanate apoptosis kit. Results: The 78 KDa and glycoprotein fractions induced more than 40% apoptosis. HCF and glycolipid antigens induced 39% and 34% apoptosis, respectively. However, less apoptosis observed after treatment with AgB fraction. Conclusion: Hydatid cyst antigens especially the 78 KDa and glycoprotein fractions induced apoptosis on mouse breast cancer cells.

Background: Achieving a rapid onset and durable methods of treatment for major depressive disorders is an issue pursuing in psychiatry. This study was designed to assess the therapeutic efficacy of intravenous (IV) ketamine injection in controlling depressive symptoms in comparison with electroconvulsive therapy (ECT) in major depressed disordered patients. Materials and Methods: Thirty-two patients over 18 years of age who were candidates for ECT were enrolled in the study. They were allocated into two groups using block design randomization. Sixteen patients received IV infusion of 0.5-mg/kg ketamine and 16 patients underwent a bitemporal ECT. To evaluate the changes in depression severity, researchers administered Hamilton Depression Rating Scale (HDRS) at baseline, before each treatment session, and four time points posttreatment (week 1 and months 1, 2, and 3). The Wechsler Memory Scale was used to evaluate the cognitive state of patients in week 1, month 1, and month 3 of the treatment. Results: The HDRS showed improvement in depressive symptoms in both the groups with no statistically significant difference. Cognitive state was more favorable (but not significant) in the ketamine group (P > 0.5). Conclusion: Treatment with IV ketamine in depressed people has the same antidepressant effects as ECT treatment without any memory deficiency.

Background: The kB family of nuclear factor (NF-κB) is a series of transcription factors that plays a key role in regulation of immunity, cell growth, and apoptosis and is considered as the main downstream component of epidermal growth factor receptor for which there are evidence of excessive activity in most cases of glioblastoma multiform (GBM). Thus, the current information has gained evidence on NF-κBIA tumor suppressor role in GMB. SNP rs1957106 was diagnosed as a new polymorphism which affected the expression of NF-κBI and causes activation of NF-κB in GBM patients. Materials and Methods: This study was conducted on 100 cases of GBM including 47 paraffin-embedded brain tissue samples and 53 blood samples from another 53 GBM patients and 150 controls. The NF-κBI rs1957106 SNP was identified by the NCBI, and genotyping was performed by high-resolution melt (HRM) assay. Melt curves from HRM which suspected to single-nucleotide polymorphism (SNP) were selected and subjected to direct sequencing. Results: The distribution of allele A of NF-κβ gene in patients with GBM with 31% was not significantly different from healthy participants (27.3%) (P = 0.375). Furthermore, the distribution of AG and GG genotypes in comparison with AA genotypes did not show a significant correlation with GBM incidence (P > 0.05). Conclusion: Findings of the present study provide evidence that the rs1957106 SNP in NF-κBIA is found more in GBM patients, but it was not statistically significant. As there are conflicting studies showing significant higher rate of this SNP in GBM, further study is suggested.

Background: Epidural anesthesia (EA) today has been used extensively in surgical procedures and the management of pain associated with midwifery and chronic pain. This type of anesthesia can be done in different technical, physiological, and pharmacological ways. The aim of this study was to compare the effects of thoracic EA with general anesthesia (GA) on hemodynamic changes and its complications in patients underwent laparoscopic colonoscopy. Materials and Methods: This clinical trial study was conducted on 80 patients undergoing laparoscopic cholecystectomy with EA or GA based on inclusion and exclusion criteria. The patients were randomly divided into two groups of 40 and changes in blood pressure, systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR), and arterial blood oxygen saturation were measured. The incidence of nausea, vomiting, chills, and itching in the two groups was recorded. The analysis was performed descriptively and also using t-test and Chi-square tests. Results: The results showed that the mean of SBP and DBP, HR, and arterial blood oxygen saturation and the incidence of nausea and vomiting was statistically significant (P < 0.05) between the two groups at 4, 6, and 12 h after anesthesia and it was higher in a group of GA. There was no significant difference in shivering and itching between the two groups (P > 0.05). Conclusion: The results of this study indicated that thoracic EA in patients with laparoscopic cholecystectomy has significant effects on factors such as SBP and DBP and arterial blood oxygen saturation. Furthermore, EA has fewer complications than GA, and it is the preferable approach

Background: This study aimed to compare the effects of preoperative administration of midazolam and dexmedetomidine on cognitive dysfunction prevention after cataract surgery. Materials and Methods: This research was a double-blind controlled clinical trial. In this study, 150 candidates for cataract surgery under general anesthesia, over 65 years, and similar to American Society of Anesthesiologists I and II characteristics were selected as the sample and randomly assigned to three groups. Participants of these three groups were treated with 0.1 mg/kg of midazolam, 1 μg/kg of dexmedetomidine, and the same volume of normal saline (control), respectively. Hemodynamic parameters and cognitive dysfunction score of the participants were measured using the Mini-Mental State Examination (MMSE) before the surgery, 24 h and 1 week after the surgery. Results: An evaluation of hemodynamic parameters before anesthesia up to 24 h after the surgery showed no significant difference between the midazolam, dexmedetomidine, and control groups in terms of systolic and diastolic blood pressure, heart rate, and blood oxygen saturation (P > 0.05). In addition, there was no statistically significant difference between the midazolam and dexmedetomidine groups in the MMSE score before the surgery and 24 h and 1 week after that (P > 0.05). However, there was a significant difference between these two groups and control (P < 0.05). Conclusion: There was no significant difference between midazolam and dexmedetomidine in reducing postoperative cognitive dysfunction (POCD). However, there is a significant difference between these two groups and control. Hence, either midazolam or dexmedetomidine can be prescribed to reduce POCD in cataract surgeries.

Background: Fluvoxamine, a well-known selective serotonin reuptake inhibitor, is used for the management of mental disorders and various types of chronic pain. In our previous study, we found the inhibitory effect of fluvoxamine on inflammatory mediator's expression. In the line of the indicated study, we sought to evaluate the effect of fluvoxamine on the expression of some inflammatory mediators such as cyclooxygenase-2 (COX-2). Materials and Methods: An in vitro model system of lipopolysaccharide-stimulated human U937 macrophages was used. The expression of COX-2 protein was measured by flow cytometry. Results: The expression of COX-2 significantly decreased by fluvoxamine in U937 macrophages. Conclusion: The results of the present study provide further evidence for the anti-inflammatory effect of fluvoxamine. This effect appears to be mediated by the downregulation of inflammatory genes. Further studies are needed to evaluate the complex cellular and molecular mechanisms of fluvoxamine.

Background: Diabetes can increase the generation of free radicals and can be harmfully effective in spermatogenesis. Crocin is a carotenoid and is accountable for the red color of saffron. Crocin has shown numerous pharmacological actions such as antioxidant roles and radical scavenging. The aim of this study was to determine the effects of crocin on sperm parameters and the diameter of seminiferous tubules in diabetic rats. Materials and Methods: In this experimental study, diabetic rats were induced by Streptozotocin (STZ) (60 mg/kg). Sixty-four rats were equally divided into the following eight groups; (1) normal control group, (2–4) crocin groups, receiving various doses of crocin (12.5, 25, and 50 mg/kg), (5) diabetic control group, and (6–8) diabetic groups, receiving STZ plus crocin (12.5, 25, and 50 mg/kg) injected intraperitoneally once a day for 28 consecutive days. The sperm count, motility, morphology, viability, spermatogenesis index (SI), and the diameter of seminiferous tubules were examined and compared. Results: The results demonstrated that count, motility, viability, normal sperm morphology, SI, and the diameter of seminiferous tubules decreased significantly in the diabetic control group compared to the normal control group (P < 0.05). However, in the diabetic groups, count, motility, normal morphology, viability, SI, and the diameter of seminiferous tubules enhanced significantly in total doses compared to those of the diabetic control group (P < 0.05). Conclusion: It seems that, as a strong antioxidant, crocin could compensate for the toxicity induced through STZ and raise the quality of some sperm parameters.

Background: Assessing the relation between dietary habits and functional gastrointestinal disorders (FGIDs) is less investigated among military personnel. In this study, we aimed to evaluate the association of certain eating patterns and FGIDs in Iranian army men. Materials and Methods: This cross-sectional study was performed on 600 army personnel working in Kerman ground forces military station number 05, Iran. Participants were asked to define their weekly breakfast consumption, lunch intake time, and chewing efficiency. FGIDs were categorized as four groups including functional dyspepsia (FD), irritable bowel syndrome (IBS), functional constipation (FC) and functional diarrhea (FDi) diagnosed by Rome Ш criteria. Relation between variables was assessed through crude and multiple stepwise adjusted models. Results: The prevalence of FD, IBS, FC, and FDi in our study was 20%, 32.3%, 3%, and 53.2%, respectively. After adjustment of all potential confounding variables, more weekly breakfast consumption was associated with decreased FDi prevalence (odds ratio [OR]: 0.57, 95% confidence interval [CI] = 0.38–0.84, P = 0.005). Slowly lunch consumption declined prevalence of IBS (OR: 0.33, 95% CI = 0.13–0.84, P = 0.02). Individuals chewing their meals well had a lower percentage of IBS, FC, and FDi (OR: 0.53, 95% CI = 0.33–0.83, P = 0.006; OR: 0.24, 95% CI = 0.06–0.89, P = 0.03; and OR: 0.52, 95% CI = 0.34–0.79, P = 0.003, respectively). Conclusions: This study suggested that increasing breakfast intake, slowly lunch consumption, and better food chewing could be effective decreasing FGIDs' prevalence and increasing army crews' quality of lives and work efficiency. Further studies required to confirm this relationship and define accurate pathophysiological mechanisms.
