Bovine β-difensin gene polymorphism can be used as a molecular marker in the selection of mastitis-resistant dairy cows. The aim of this study was to investigate the relationship between point mutation of β4difensin gene and the occurrence of clinical mastitis in the dairy cows using RFLP-PCR method and identification of superior genotype of dairy cows β-difensin gene for mastitis resistance. Material and Methods: blood sample (with EDTA anticoagulant) was taken from total 73 cows (32 with a history of mastitis and 41 with no history of mastitis) in an industrial dairy farm. After DNA extraction amplification of the region of bovine β-difensin gene (393 bp) was performed. PCR products were digested by endonuclease (NlaIII (Hin1II)) for rapid detection of polymorphism in the 2239 region of the β-difensin gene (C to T conversion). Statistical analysis was performed by Chi-square test. Results: Allele frequencies were 0.68 and 0.32 for C and T, respectively. Statistical analysis was performed by Chi-square test. The results of this study indicate the association between number of mastitis and polymorphism in the β-difensin gene. In other words, the incidence of mastitis was numerically lower in cows with T allele than in cows without it (p=0.07). Conclusion: It can be concluded that the bovine β-difensin gene can also be used as a molecular marker in the selection of dairy cows to reduce the incidence of mastitis.

Formulating and executing the successful aging policy and plans not only result in living longer, but also lead to a healthier and better quality of life for them. Given that investigating the effective factors for successful aging is the first step for promoting different aspects of their health, the present study was conducted to determine the predictors of successful aging in the elderly of Qazvin city. Materials and Methods: This descriptive and crosssectional study was conducted on 291 older people residing in Qazvin city in 2017. The elderly were selected using the cluster sampling method. Demographic characteristics checklist, successful aging, cognitive performance, SF-12 quality of life, Keyes social health questionairs, the satisfaction with life and Palutzian-Elison spiritual well-being scales were used for gathering the data. The questionnaires were completed with face to face interview by the researcher. Data were analyzed through Pearson, Spearman, independent t-tests and stepwise multivariate regression analysis was made using SPSS software, version 23. Results: The mean age of the elderly participating in the study was 34.68 with the standard deviation of 76.6 and with ranging from 60 to 87 years old. Results of the stepwise regression analysis showed that the independent variables included in the multivariate regression could predict 44% of the successful aging. The results also showed that the job (p = 0.002), income (p = 0.000), lack of emotional problems (p = 0.000), history of chronic illnesses (p = 0.004), cognitive function ((p = 0.047), physical health (p = 0.000), life satisfaction (p = 0.032), social health (p = 0.021), and The existential dimension of spiritual well being (p = 0.000) as predictors of successful aging were obtained. Conclusion: Considering the growing trend of aging in the country, there is an increasing need for special attention to this group of society. Successful aging causes to promote the person and finally, society. Therefore, studying the parameters affecting the successful aging can improve it. Therefore, the prevention and health managers and members of the therapeutic team must pay more attention to these cases.

The purpose of this study is integrated risk and asset management by implementing risk-based inspection techniques in the oil, gas, and petrochemical industries. Methods: Firstly, this systematic review study identified a list of keywords based on RBI and then exclusively on the internal and external databases of Science Direct, Pub med, Google Squalor, SDI, Google Searcher, and Scopus without a time limit. Afterward, keywords, including risk management, probability of failure, asset integrated management, risk-based inspection, consequences of failure, and corrosion management, were searched. Result: A review of various studies showed that the risk-based inspection approach provided the necessary platform for upgrading and formula...

It's an illegal issue in Iran. This study aimed to examine the attitude towards euthanasia in nursing students, and its relationship with their personal beliefs' level. Methods: The current cross-sectional study was conducted in Qazvin during the education year of 2017-2018. The samples of this study consisted of 121 nursing students who were studying at the Qazvin University of Medical Sciences for more than two semesters. The Euthanasia Attitude Scale and Palutzian and Ellison Spiritual Wellbeing Scale were used for the data collection. Results: The response rate was 73.3% (121 of 165 nursing students). All of nursing students in the present study were Muslim. The mean overall scores of attitudes towards euthanasia and spiritual wellbeing were 60.24±9.82 and 75.73±7.48, respectively. No significant relationship was found between attitude towards euthanasia and personal beliefs among them (p=0.204). Conclusion: Iranian nursing students reported a relatively neutral attitude towards euthanasia which is mainly related to its legal issue in Iran. Also, no significant relationship was observed between attitude towards euthanasia and personal beliefs among the participants. Further studies are needed in this regard.

Phototherapy causes the separation of mother and infant, interfering with breastfeeding and there are also some concerns regarding to destruction of the genetic materials. Methods which might reduce the rate of photo would be useful. In this study, we compare the results of continuous and intermittent phototherapy methods on bilirubin levels of infants with hyperbilirubinemia. Materials & Methods: This study was a randomized clinical trial study which has been undertaken on 100 newborn infants, those who hospitalized in Bandar-Abbas hospital. Using simple Randomization technique, infants were divided into two groups. First groups were 39 newborn infants who were undertaken in intermittent phototherapy (phototherapy was one hour on and one hour off) and the rest (45 infants) were in continuous phototheraphy (phototherapy wa...
