Background and Objective: Genital herpes is increasing in Asia and the world. Based on other studies, knowledge has an important role in reducing high risk sexual behavior. In this study we evaluated knowledge among Shahid Beheshti University students as a sample of young and educated population of Iran. Materials and Methods: This cross-sectional study carried out on 409 of Shahid Beheshti University students in Tehran - Iran at Autumn 2004. Research material was questionnaire and data analyzed by SPSS-13, T-student, Chi-square, Mann-Whitney, Kruskal-Wallis Tests. Results: Mean±SD of level of knowledge, nature and transmission of genital herpes was 26.5±26%, 23.7±24.2% and 30.56±36.8%, respectively. The level of knowledge about signs, treatment and prevention of disease was 18.8%, 16.4% and 46.2%, respectively. There was a significant relation between age, marital status and education with knowledge (P<0.05). The level of knowledge among engineering students was higher than humman sciences students (P<0.05). Conclusion: Based on our study, most of participants had no enough knowledge about genital herpes. Most of participants were willing to know more about it as they obviously welcomed to our pamphlets. It seems that educations about genital herpes should be added to educational programs.

Background and Objective: Diabetes mellitus is one of the most common serious metabolic disorders characterized by hyperglycemia, altered metabolism of lipids, carbohydrates and proteins. Gestational diabetes mellitus (GDM), affects 3.5–5% of all human pregnancy. Therefore, this study was done to evaluate the effect of gestational diabetes on astrocyte density in CA1 and CA3 subfields of hippocampus in rat male offspring.

Materials and Methods: In this experimental study, 12 Wistar Dams rats were randomly allocated in control and diabetic groups. Gestational diabetes induced by 40 mg/kg/body weight of streptozotocin at the first day of gestation (GD) in experimental group and controls were received an equivalent volume normal saline injection intraperitoneally (IP). Six male offspring of cases and controls dams, at the 7, 21 postnatal day (P7, P21) were randomly selected. Animals were scarified using chloroform anesthesia. The coronal sections of brain by 6 micrometer serially were prepared. The sections were stained with PTAH. The number of astrocytes was evaluated in 100000 μm² area of CA1 and CA3 in 1000X magnification. Data was analyzed by SPSS-11.5 and t-test.

Results: In CA1 subfield of hippocampus in offspring, the number of astrocytes  significantly reduced by 36.25% and 36.37% in diabetic group in compare to controls in the P7 and P21, respectively (P<0.05). In CA3, astrocytes density significantly reduced 36.35% and 26.5% in GD in comparison with controls in the P7 and P21, respectively (P<0.05).

Conclusion: This study showed that the uncontrol gestational diabetes significantly reduces astrocytes density in CA1 and CA3 subfields of hippocampus in rat offspring.

Background and Objective: Valproic acid is used in the epilepsy, bipolar and migraine therapy. As a histone deacetylase inhibitor, Valproic acid has been recently under investigation in cancer treatment, either alone or in combination with either chemotherapy or radiotherapy. This study was done to determine the effect of Valproic acid and radiotherapy on viability of MCF-7 breast cancer cell line. Methods: In this descriptive - analytic study, MCF-7 cell line was obtained from the Iranian Pasteur Institute. The cells were treated and incubated by different concentrations of Valproic acid (1, 2, 4, 8, 16, 32, 64 and 128 mM) either alone or in combination with various dosages (0 .5, 2, 4, 6 and 8 Gray) of radiotherapy. After cell viability assay, using the Neutral red staining, the most nearest results to LD50 were selected. Cell viability was evaluated with trypan blue staining. Results: The most nearest concentrations of LD50 was doses of 2, 8 and 16 mM of valproic acid and dosage of Gray 4 of radiation. There was a significant dose-dependent correlation between reduction of cell viability with valproic acid concentration (P<0.05). Conclusion: Valproic acid, either alone or combination with radiotherapy caused a significant decline in the cell viability of MCF-7 breast cancer cell line.

Background and Objective: Fetal heart pattern is one of the most important criteria in non stress test. This study was done to compare the effect of two anxiety- reducing methods, maternal relaxation and fetal-maternal attachment skills training on the prevalence of sporadic fetal heart decelerations and heart beat variability. Methods: In this clinical trial study, 126 pregnant women were randomly divided into three groups including teaching relaxation, maternal-fetal attachment skills and controls. Training was done for four weeks. NST was performed 30 minutes before of traning and after 4th week of training in the interventional groups. In the control group, NST was done in the 4th week. Cranley scale was filled at the end of the study. Results: The prevalence of sporadic deceleration in attachment skills, relaxation and control groups before intervention was 23.8%, 19% and 21.4%, respectively. After the intervention, the prevalence of sporadic deceleration in attachment skills group non-significantly changed to 11.9%. After the intervention the prevalence of sporadic deceleration in the relaxation group significantly changed to 4.8% (P<0.05). Conclusion: Maternal relaxation training decreased the prevalence of sporadic fetal heart decelerations, and enhances fetal heart beat variability.

Background and Objective: The elderly population is rising rapidly in the world and one of the criteria for assessing the needs and health of the elderly is life quality. Mindfulness is a kind of consciousness, and it comes about when we encounter our experiences with a more precise and detailed in the present and without judgment. This study was done to determine the effect of mindfulness training on personal well-being and mental health in elderly women.
Methods: This quasi-experimental study was done on 46 elderly women over 60 years of age who displaced in the only daily nursing home in Gorgan, northern Iran .The subjects were non-randomly divided into the intervention and control groups. The intervention group participated in eight sessions of two-hour mental education training. Personal information questionnaire, general health questionnaire-28 (GHQ-28) and personal well-being index – adult (PWI-A). PWI-A and mental health questionnaires were completed by the elderly at the beginning and the end of the study.
Results: In the intervention group, mindfulness education significantly increased the subscale of personal well-being in the post-test (57.4±3.5) compared to the pre-test (43.2±10.6), and the subscale of mental health and its components in the post-test (13.47±5.5) compared to the pre-test (35.6±10.9) (P<0.05). In the control group, the subscales of personal well-being and mental health and its components at the prior and the end of the study was not different.
Conclusion: Mental education improves subscales of personal well-being and mental health in elderly women.

Background and Objective: Irrational beliefs underlie a wide range of cognitive impairments. This study was performed to compare the effect of cognitive-behavioral therapy and acceptance and commitment therapy on irrational beliefs of medical students.
Methods: In this quasi-experimental study, 45 medical students of Golestan University of Medical Sciences in north of Iran were non-randomly divided into control, cognitive-behavioral therapy (first intervention) and acceptance, commitment therapy (second intervention) groups. All three groups completed the pre-test, but the control group did not receive any therapy. The intervention groups were received 8 sessions of therapy. The data were collected through Jones's 1969 (IBQ-40) irrational beliefs questionnaire.
Results: The total score of irrational beliefs in the both intervention groups were reduced in comparison with control group (P<0.05). The mean score of the problem-based avoidance subscale (35.26±6.32) was significantly reduced in the second intervention group compared to the first intervention group (30.53±9.47) (P<0.05). Also, the mean scores of emotional impulsivity in the first intervention group (22.73±9.49) were significantly increased compared to the second intervention group (29.93±1.75) (P<0.05).
Conclusion: Two methods of cognitive-behavioral therapy and acceptance and commitment therapy reduce the irrational beliefs of medical students.

Background and Objective: Fibromyalgia syndrome is a chronic disease with extensive musculoskeletal pain that primarily involves women and also it has negatively effects on many aspects of psychological and social life. Cognitive-behavioral therapy examines dysfunctional emotions and maladaptive cognitive behaviors, processes, and themes, and cognitive-behavioral hypnotherapy combines hypnotherapy with the methods and concepts of cognitive-behavioral therapy. The aim of this study was to compare the effectiveness of cognitive-behavioral therapy with cognitive-behavioral hypnotherapy on sexual satisfaction of women with fibromyalgia syndrome.
Methods: This clinical trial study was done on 9 women with fibromyalgia syndrome who referred to rheumatology clinic in Gorgan, northern Iran in 2020. The patients were randomly divided into three groups including cognitive-behavioral therapy, combination cognitive-behavioral hypnotherapy and control group. The treatments used were performed for 8 sessions separately for 2 groups of 3 people in Pars Tavan Comprehensive Center. Control group did not receive any intervention. A multidimensional sexual satisfaction questionnaire of Roshan 2014 was used to evaluate patients.
Results: Sexual satisfaction in post-test on both interventional group showed a significant improvement compared to control group (P<0.05). Cognitive-behavioral hypnotherapy with 59.38% was more effective than cognitive-behavioral therapy with 43.01 and also it was the same 2 month after follow up (P<0.05).
Conclusion: Combined therapy of cognitive-behavioral hypnotherapy increased sexual satisfaction in women with fibromyalgia syndrome more than cognitive-behavioral therapy.

Background and Objective: Paraquat toxicity can damage organisms through mechanisms that are not yet fully understood. Evidence shows that regular exercise and appropriate antioxidant supplements can help reduce the complications caused by paraquat toxicity. This study aimed to evaluate the effect of aerobic exercise training, along with piperine supplement, on the liver levels of tumor necrosis factor-alpha (TNF-a) and interleukin-10 (IL-10) in Wistar rats induced with paraquat.
Methods: In this experimental study, 40 adult Wistar rats were randomly placed into 5 groups of 8, including 1) sham, 2) negative control-paraquat, 3) paraquat + training, 4) paraquat + training + piperine, and 5) paraquat + piperine. Aerobic training included 7 weeks of walking on a treadmill (5 sessions per week for 30-40 min per session, at a speed of 10-18 m/min). Paraquat was administered to the rats by intraperitoneal injection at a dose of 5 mg/kg of body weight. The piperine supplement was daily gavaged at a dose of 10 mg/kg of body weight. The concentration of TNF-a and IL-10 was measured in the liver tissue.
Results: A significant increase in IL-10 and a decrease in TNF-a concentrations were observed between the paraquat-negative control groups compared to the sham, paraquat + exercise, paraquat + piperine, and paraquat + exercise + piperine groups (P<0.05). There was a significant difference between the mean concentrations of TNF-a in the liver tissue between the two negative control groups - paraquat with paraquat + piperine supplement (P<0.05), paraquat + exercise + piperine (P<0.05), paraquat + exercise (P<0.05), and sham (P<0.05). There was a significant difference in concentrations of IL-10 in the liver tissue between the two negative control groups - paraquat with paraquat + piperine supplement, paraquat + exercise + piperine, paraquat + exercise), and sham (P<0.05).
Conclusion: The concentration of TNF-a and IL-10 in male rats induced with paraquat were significantly decreased and increased, respectively, compared to paraquat + piperine supplement, paraquat + exercise + piperine, paraquat + exercise, and sham groups. Therefore, it seems that performing aerobic exercise, along with piperine supplementation, can be a proper way to reduce the inflammation caused by paraquat.
