The present study was conducted in order to compare the self-concept and family emotional condition among delinquent adolescents who stay in Ahvaz adolescent’s correction center with a normal control group.

This investigation is a descriptive and comparative cross-sectional study. Our population includes all delinquent boys who stayed in Correction and Nurturance Center of Ahvaz in addition to all of the high school students from four educational regions in Ahvaz city, during 92-91 school year. 60 participants were randomly selected and assigned in two groups (n=30). Hill Bern family emotional condition scale and Self-Perception Scale (from Mandaglio & Pyryt) were used to measure research variables. To compare two groups, data were analyzed with independent t-test.

The results showed that there is significant difference between two normal and delinquent groups of adolescents in terms of family emotional condition and self-concept.

According to our findings, it seems that inappropriate family emotional climate effects on self-concept formation in delinquent adolescents.

The aim of this study is to compare dimensions of family functioning in addicts and normal people. To achieve the goal, 50 addicts and 50 normal people were selected by convenience sampling in Tabriz city. Data were collected with use of demographic characteristics and family functioning questionnaires. Data were analyzed using SPSS 20 software with multivariate analysis of variance (MANOVA). The results showed that among the components of family functioning, overall performance, problem solving, communication, roles, affective involvement and behavior control were significantly different between addicts and normal people. But no significant difference was found between the groups in the term of emotional solidarity. The results indicated family dysfunctioning in addicted family. Therefore, according to this study, fundamental substance abuse prevention interventions are highly suggested.

Nurses must stay awake during the night to provide nursing cares. This can cause sleep problems in these personnel. The aim of this study was to assess the prevalence of sleep disorders among military nurses. A sample of 272 nurses who were randomly selected with a multi stage cluster method, participated in this cross sectional study. Sleep quality and day time sleepiness were assessed based on Pittsburgh Sleep Quality Index and Epworth sleepiness scale. Demographic characteristics were also collected and all data analyzed with SPSS 15. Of 272 studied nurses, 43% were male and 57% were female. Daytime Sleepiness score was achieved 16%. Most of the nurses had a degree of sleep disruption (63.8%) and only 10.9% had not had any sleep disorders. Due to similar rate of sleep disorders and sleepiness in military nurses to other shift work personnel, necessary measures should be similarly taken to reduce this problem.

Lifestyle is one of the important factors that affect human health. Today most problems of health, such as obesity, cancer, hypertension and disease and resulted mortality are associated with lifestyle. The aim of the present study was to compare the lifestyle of military personnel and civilians. This descriptive-comparative study was conducted with 200 people, including 100 military and 100 civilians in Tehran. Convenience sampling method was used to selected subjects. Lifestyle questionnaire developed by researchers in four main dimensions (nutrition, stress, smoking and physical activity) was used to collect research data. The mean age of the military group was 40.1 (5.58) and in non-military group was 40.46 (5.52) years. Optimal amount of carbohydrates, fruits, fat consumption of and the mean of physical activity were higher in the military group. However, optimal amount of protein consumption and the mean of stress levels and smoking were higher in non-military (p<0.05), there was no statistically significant difference in the amount of dairy products consumption between two groups. According to the importance of lifestyle in personal health and the necessity of paying attention to all aspects of military and civilian lifestyle, we suggest organized and comprehensive interventions which are consistent with the condition of subjects.

The aim of this study was to recognize identify the effective factors on empowerment among military healthcare personnel. This descriptive study was conducted on 210 workers from Headquarter of Police Medicine in 2011, who were selected with random sampling method. The tool used to collect information was questionnaire. Reliability and validity of questionnaire were confirmed by Cronbach´s Alpha Coefficient (0/839) and content validity methods. Descriptive and inferential statistics (Spearman Correlation Coefficient Test and Friedman Test) were used to analyze data with SPSS software version 19. Results reveal that: there was a significant relation between contextual, structural and behavioral factors and empowerment. Moreover, ranking the variables showed that the highest rate is related to behavioral factors with the mean of 2.28 and the lowest related to contextual ones with the mean of 1.78. According to the finding of the present research, to improve the existing status, designing a native model of management style and empowerment with the approach of job motivation promotion and revision of organizational training courses, is highly suggested.

Polyhydroxybutyrate is a biodegradable plastic that has widespread application in various industries and in the field of medical equipment production. In E.coli, the most cost of Polyhydroxybutyrate production (PHB) is related to its extraction and purification processes. E gene of Phage Фx174 with conformation of membrane tunnel is used for lysing the hosted bacteria. This study was conducted to investigate the function of E gene in conformation of membrane tunnel and release of produced PHB in E.coli. In this study, after amplification with polymerase chain reaction (PCR), PHB operon was cloned by pUC18 while its expression controlled by operon promoter. E gene was amplified with PCR and cloned by pMR103 plasmid while it’s expression controlled by T7 promoter. Lysis process and conformation of membrane tunnel were evaluated by electronic microscope. Analysis of produced PHB was performed by gas chromatography and Sudan staining. With activation of E gene and lysis of bacteria, optical density of specimen decreased. In the analysis of bacterial debris which achieved from E.coli medium by electronic microscope, we observed membrane pores in lysed bacteria. The results of gas chromatography and Sudan staining showed that PHB granules have been released to medium by conformation of membrane tunnel. Lysis E gene can be used for decreasing the cost and facilitating the extraction of PHB in E.coli that can be applied for manufacture of disposable medical and operating room equipment.

Breast cancer is the most common type of malignancy in women. Despite dramatic achievements in the development of synthetic pharmaceutics, herbal drugs still remain as one of the leading therapeutic strategies for cancer. In the current study, we aimed to investigate the toxic effects of dendrosomal nanocurcumin on 4T1 cells derived from BALB/c mice breast tumors. For this purpose, MTT assay was exploited to evaluate viability of 4T1 cell line and mouse skin normal fibroblasts (MEF) cells under exposure to nanocurcumin. Cultured cells were treated with different concentrations of nanocurcumin ranging from 5 to 45µM. Furthermore, the effect of nanocurcumin on cells was compared with doxorubicin as a frequently-used chemotherapeutic for breast cancer. The results of MTT assay indicated that treatment with nanocurcumin leads to a significant reduction in the viability of cancer cells in a dose- and time- dependent manner with no significant effect on normal cells. The decrease in viability of cancer cells was 35, 25 and 15µM for 24h, 48h and 72 h post-treatment, respectively. The data also shown that nanocurcumin exerts toxic effects the same as doxorubicin on cancer cells. Given less toxicity of nanocurcumin on normal cells in comparison with doxorubicin, this finding is of paramount importance. Dendrosomal nanocurcumin is able to eradicate cancer cells in a dose- and time-dependent mode. This nanodrug has toxic effects on breast cancer cells with no toxicity on breast normal cells. On the other hand, this therapeutic agent is as potent as doxorubicin in killing cancer cells. While compared with doxorubicin, this compound shows less toxicity on normal cells.

Chronic neck pain is one of the common problems among computer users. The aim of this research was evaluation the effect of therapeutic exercises programs on the rate of chronic neck pain and disability in police staff in Lorestan Province. In this semi experimental study, thirty patients with chronic neck pain with the mean age: 35.73 ± 5.68 years, height: 176.00 ± 5.43 cm and weight: 72.9 ± 10.61 and with at least six months history of neck pain were recruited by personal information questionnaire among computer users of the Police Headquarter of the Lorestan Province. The subjects were divided into two groups with 15 subjects. First group received therapeutic exercises by pamphlet, while the second one was the control group that did not receive any intervention. Neck pain and disability were measured by Neck Pain and Disability Scale at baseline and after 8 weeks intervention period. For analyzing data, first the differences between quantities of pre and post tests were measured, then evaluated by independent t- test (P<0.05). Pearson correlation was also used to consider the relation between variables. The results showed that neck pain and disability in experimental group were significant decreased compared with the control group (p<0.05). But Pearson correlation showed that there was no significant relationship between neck pain, disability and the subjects work experience (p =0. 84, r = -‌0.37). According to the results of this study, it can be concluded that treatment by pamphlet would be useful for treatment of chronic neck pain. Consequently, it seems that applying this method was more helpful for the rehabilitation of patients with chronic neck pain and so it is highly recommended.
