The aim of the present study was to investigate the role of mindfulness, emotion regulation skills and perception of the family's emotional environment in predicting cyber bullying.

The present research method is descriptive-correlation type and the research sample was 304 female students of the second secondary school in public schools of Tabriz city, who were selected by multi-stage cluster random sampling method. The tools used in this research are the cyber bullying questionnaire of Antoniodo et al. the mindfulness of Ryan and Brown, the emotional regulation skill questionnaire of Gross and John and the questionnaire parenting styles based on the work of Schiffer. Data were analyzed using Pearson's correlation coefficient and multiple regression analysis.

Data analysis using Pearson's correlation coefficient showed that the relationship between mindfulness and evaluation of emotion regulation skills and cyberbullying is negative and significant (P<0.05). The relationship between the emotional suppression dimension of emotion regulation skills and the affection dimension of perception of the emotional environment of the family and cyberbullying is positive and significant (P<0.05). Based on the results of regression analysis, mindfulness, emotion regulation skills and perception of the family's emotional environment are able to predict cyberbullying and explain its occurrence in certain circumstances (P<0.05).

Psychologists and educational counselors should provide counseling in the field of improving mindfulness, teaching emotion regulation skills, and providing counseling to parents in order to prevent cyber bullying in students.

the study of antibacterial properties of resin cements and modified glass ionomers is of great importance. The aim of this study was to determine the antibacterial effect of resin-modified glass ionomers and resin cements on cariogenic bacteria, Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus.

In this experimental laboratory study, samples of Streptococcus mutans,Streptococcus sabrinus and Lactobacillus acidophilus were used. 7 samples were prepared from each of glass ionomer and resin cements. After drying and sterilizing the samples, the quality control operations of the samples were performed and cultured in culture media at 37 ° C for 48 hours. According to the antimicrobial halo around each disk, its measurement the growth or non-growth of bacteria was examined. Data were analyzed using t-test and two-way ANOVA

The diameter of growth inhibition zone of the three studied bacteria in the presence of three materials SDI seT PP, Natural Elegance and GC Fugi Plus was significantly different (p <0.001). The diameter of GC Fugi Plus stunted halo in all three types of bacteria was larger than other groups and the stagnation halo diameter of Lactobacillus acidophilus was larger than that of Streptococcus mutans without any difference with Streptococcus sabrinus.

The antibacterial effects of glass ionomer cement are more than the other two types of resin cements. Also, the antibacterial effects of the investigated cements on Lactobacillus acidophilus were higher than other bacteria.

In recent years, several studies have shown the association between exercise and decreased risk of mortality in patients with breast cancer. However, the effects of combined resistance and endurance training on salivary Interleukin-12 (IL-12), tumor necrosis factor (TNF-α), Cortisol, and Testosterone levels in patients with breast cancer have not been investigated.

This study aimed at determining the effect of 8 weeks of combined resistance and endurance training on salivary IL-12, TNF-α, Cortisol, and Testosterone levels in women with breast cancer.

Forty-two postmenopausal women with breast cancer were randomly selected and divided into training (intervention) and control groups. The training group performed resistance training with 2 to 3 sets, 10 to 18 repetitions, 50 to 70% 1 repetition maximum (1RM), and aerobic exercise with 50 to 70% maximum heart rate (maxHR) (12-14 degrees borg scale) for 20 to 40 minutes for 8 weeks. The salivary IL-12, TNF-α, cortisol, and testosterone levels were measured, using the enzyme-linked immunosorbent assay (ELISA) method. Two-way analysis of variance repeated measure was also used to analyze variance with the confidence interval of 95%.

In the training group, there was a significant decrease in salivary TNF-α levels, cortisol, TNF-α/IL-12 ratio, and variables of weight, fat percentage, body mass index (BMI), and waist circumference (P < 0.05). Also, the results showed a significant increase in salivary testosterone and testosterone/cortisol ratio in the intervention group (P < 0.05). However, no significant changes were observed in the interaction between-group and time in IL-12 and waist–hip ratio (WHR) values (P > 0.05).

The results indicate that resistance and endurance training could be used as a useful method to improve salivary pro-inflammatory factors and hormonal levels in patients with breast cancer. Medical oncologists can underline a resistance and endurance training program for patients with breast cancer under their care.

Clinical education is a process in which students gradually acquire clinical experience and prepare themselves to solve patient's problems. Choosing the appropriate educational method is one of the most important parts of education. The aim of this study was to determine the level of learning in different educational methods using the attitudes of graduate students in major and minor department. In this descriptive-analytical study, 82 (64%) out of 128 graduated students from the faculty of medicine were evaluated by a researcher-made questionnaire consisting of 10 questions with five-choice Likert scale and demographic information. The face and content validity was confirmed by the faculty members and its reliability was confirmed with the Cronbach Alpha’s coefficient of above 80%. There was a significant relationship between gender, marital status, number of children, type of entrance quota, and average score with different educational methods. Individual study and outpatient clinics had the most impact and journal club meetings had the least impact on learning. Grand round had a great impact on women's learning, the outpatient clinic on learning of free-quota students and mortality and morbidity sessions, student conferences, and individual study on higher-grade students. It is recommended that educational managers and planners consider the content and type of educational programs in the mentioned sections, considering the impact of different educational methods on learning. Due to the lack of similar studies on the attitudes of the education and training staff, further research is needed in this regard

Lung cancer is the fifth most common cancer in Iran, with 10.5 and 1.5 per 100,000 in males and females, respectively. The study of latent tuberculosis infection (LTBi) in patients with lung cancer is significant due to the possibility of its activation during chemotherapy and increased mortality. Therefore, the aim of this study was to compare the prevalence of LTBi in patients with lung cancer with healthy individuals.
In this case-control study, which was performed from 2016 to 2017, 29 patients with newly diagnosed lung cancer and 40 healthy subjects were studied. Demographic data of all subjects were recorded in questionnaire. IGRAs (Quantiferon) were used to determine the LTBi.
The results of this study showed that prevalence of LTBi were 24.1% in lung cancer and 22.5% in the healthy group. The results of this study showed that smoking had a significant relationship with the risk of lung cancer and also LTBi infection in healthy people (p Since LTBi activates under chronic conditions such as malignancies, and because of high rates of LTBi in patients with lung cancer, it is recommended that screening for LTBi in high-risk individuals such as Lung cancer patients should be done before any treatment. Considering the role of smoking in lung cancer as well as the ability to develop LTBi in healthy people, attention to cessation of smoking in the health care program, prevention and treatment of pulmonary patients is recommended.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma, which often appears in the form of patches, plaques, and tumors as originally described by Alibert and Bazin. The manifestation of MF as annular lesions is uncommon, and herein we report one of those cases. A 54-year-old woman complaining of itchy skin lesions from three years before, came to our clinic with no response to topical steroids. In skin examination, there were annular lesions with erythematous slightly raised borders, and some scattered erythematous thin plaques in trunk and extremities with a predilection to lower extremities. Epidermal and poikilodermic changes were not evident. There were no lymphadenopathy and hepatosplenomegaly. Biopsies were obtained from three different lesions and the diagnosis of all samples was consistent with MF. A diagnosis of stage 1B of MF was made and the patient went under oral psoralen and ultraviolet A (PUVA) therapy. MF has different clinical manifestations that can be confused with other inflammatory dermatological disorders. Until now, less than 10 cases of MF with annular lesions have been reported in the English literatures, and most of them initially were under treatment with other differential diagnosis of annular lesion than MF

Pregnancy is associated with significant changes in calcium metabolism. During pregnancy, calcium absorption increases through the digestive tube and with high concentration of vitamin D. During pregnancy, vitamin D increases HPL-HCG, estrogen and progesterone in a ripe placenta, and its deficiency during pregnancy increases preeclampsia, gestational diabetes, toothache, anemia and bacterial vaginosis in mother, and may cause postpartum seizures, PTL, SGA, IUGR, osteomalacia, infantile rickets, and craniotabes in newborn infants.

This cross-sectional study with a developmental plan has been conducted in the first trimester of pregnancy (week 12) on the women referred to Shariati and Al-Zahra Teaching Hospitals, Isfahan, Iran in 2012-2013. The study was done in a range of one year and 280 individuals were selected after statistical calculation. Sample collection method has been convenient and for each sample Vit D (OH) 125 was requested during the first trimester of pregnancy. Samples were taken from the patients and following testing standards, tests were performed in laboratory. Vitamin D level was measured using E-lex's and Electrochemi-luminescence method (ECLIA), and information related to supplements received by the mothers, general situation of health, use of medicine during pregnancy, pre-pregnancy weight, first trimester weight, maternal age, place of living, receiving vitamin D, maternal hemoglobin level, bacterial vaginosis infection, and toothache in the first trimester were collected through questionnaire and analyzed in the survey. All data were stored in SPSS software and then analyzed using t-test and chi Square tests.

Vitamin D level in 280 pregnant women ranged from 1 to 80. Vitamin D deficiency was examined in four groups of severe deficiency (0-20), moderate deficiency (20-40), mild deficiency (40-60) and normal (higher than 60), and a significant relationship was observed between vitamin D level and associated factors.

In this study, anemia, bacterial vaginosis and toothache were more observed in the mothers with low levels of vitamin D.

The role of nutrition in the progression of multiple sclerosis (MS) and related complications such as fatigue has been reported by several studies. The aim of this study is the assessment of nutritional status and its relationship with fatigue in multiple sclerosis patients. This is a cross-sectional study, in which 101 relapsing-remitting MS patients were enrolled. The fatigue status was determined using the validated Persian version of of the Modified Fatigue Impact Scale (MFIS). Dietary intake was assessed using a 3-day food record questionnaire and compared to dietary reference intake (DRI) values. Association between variables was determined using Pearson Correlation Coefficient. In the preset study, 25 men and 76 women (total = 101) were enrolled. Analysis of dietary intake showed that daily intake of vitamin D, folate, calcium, and magnesium were significantly lower than DRI in all of patients. In men, zinc intake was significantly lower than DRI; while, in women, iron was significantly below the DRI level. After adjusting for energy, MFIS and its physical subscale were highly correlated with intake of folate and magnesium. Our findings support that lower magnesium and folate diets are correlated with higher fatigue scores in MS patients.
