ABSTRACT

Selection and breeding for high-yielding in oilseed rape have always been one of the leading objectives for oilseed rape breeders. This process becomes more complicated when all quantitative traits are considered in selection in addition to grain yield. In the present study, 18 oilseed rape genotypes along with 2 check cultivars (RGS003 and Dalgan) were evaluated across 16 environments (a combination of 2 years and eight locations) in the tropical climate regions of Iran during 2018-2019 and 2019-2020 cropping seasons. The experiments were conducted in a format of randomized complete block design (RCBD) with three replications. The obtained multienvironmental trial data were utilized to conduct multivariate analysis, genotype by trait (GT) biplot, and genotype by yield*trait (GYT) biplot (Breeding, Genetics and Genomics, 1:2019). The GT and GYT biplot accounted for 55.5% and 93.6% of the total variation in the first two main components. Based on multivariate analysis and GT biplot, pod numbers in plant (PNP) and plant height (PH) were chosen as two key traits in spring oilseed rape genotypes for indirect selection due to high variation, strong positive correlation with grain yield (GY), and their high representatively and discriminability in genotype selection. The mean × stability GT biplot represented G10 (SRL-96-17) as the superior genotype. Based on the mean × stability GYT biplot, eight above-average genotypes were identified that took high scores in stability, high-yielding, and all evaluated quantitative traits at the same time. Based on the superiority index of GYT data, G10 (SRL-96-17) and G5 (SRL-96-11) indicated the best yield-trait combinations profile and ranked above check cultivars and then selected as superior genotypes. Similarly, cluster analysis using the WARD method also separated eight superior genotypes. Based on the result of the present study, GT ad GYT methodologies are recommended for trait profiling and genotype selection in oilseed rape breeding projects, respectively.

ABSTRACT

Nuclear technology is currently used as a tool in mutation breeding to improve crops by increasing genetic variation. The ionization of gamma rays produces large amounts of free radicals, simulating stressors in the natural environment. To avoid gamma-ray-induced oxidative stress, plants use antioxidant defense systems. Exposure of plants to irradiation can affect the germination, growth, and production of metabolites. Plants' sensitivity to irradiation depends on genetic and environmental factors such as moisture content. For this purpose, the effects of different gamma irradiation doses [0, 100, 200, 300, and 400 Gray (Gy)] and different seed moisture contents (7, 13, and 19%) on traits such as seed germination, seedling growth, molecular and biochemical alterations in antioxidant enzymes were examined in the current study. Based on the results, the highest seed germination percentage was observed in the interaction effect of seed moisture at 13% with an irradiation dose of 400 Gy (98.89%). Seedling survival percent and seedling length decreased with increasing doses of gamma irradiation at different seed moisture contents. Increasing gamma irradiation doses were reduced root and stem fresh and dry weight, and root and stem length. The highest level of catalase enzyme activity and expression was observed at 200 and 300 Gy irradiation doses at different moisture contents. The peroxidase and polyphenol oxidase gene expression were reduced at all contents of gamma irradiation doses and seed moisture compared to the control. It can be concluded that the dose of 200-300 Gy of gamma irradiation reduced plant growth by 30% in terms of fresh and dry weight and length of plants, as well as enhanced the expression of antioxidant enzymes. The results of this study could help plant breeders select an appropriate dose rate in wheat for further research.

ABSTRACT

OBJECTIVES: Since an individual's personality and behavior are mainly shaped in the family environment, parental substance abuse and its consequences can lead to confusion and instability in the family environment and reduce child-parent relationship. This study was conducted to investigate the relationship between different aspects of parental communication patterns and self-efficacy in adolescents with parental substance abuse. MATERIALS & METHODS: In this descriptive correlational study, a total of 100 adolescents with parental substance abuse were selected via random sampling. The data collection tools included the parental communication patterns scale and self-efficacy questionnaire. Data were analyzed in SPSS version 20, using linear regression analysis and Pearson's correlation coefficient test. RESULTS: The mean age of the adolescents was 14.5±2.5 years. Pearson's correlation coefficient showed that the adolescents' self-efficacy score was directly correlated with the score of conversation orientation dimension (a parental communication pattern) and inversely correlated with the dimension of conformity orientation (P<0.001). CONCLUSION: Development of educational programs to promote communication skills, positive family interactions, decision-making, and flexibility can change the unhealthy family environment into a healthy and productive one, which promotes self-efficacy beliefs in children.

ABSTRACT

OBJECTIVE: Use of narcotics to relieve pain in labor affects neurobehavioral and nutritional conditions of newborns after birth. However, there are inadequate data on the effects of drugs currently used in labor. This study was performed to examine the association between newborns' breastfeeding behaviors in the first two hours after birth and drugs used for their mothers in labor in Isfahan, central Iran, from 2014 to 2016. MATERIALS & METHODS: In this descriptive-analytical study, 300 women were selected who had vaginal delivery in the Labor and Gynecology Wards of Al-Zahra and Shahid Beheshti hospitals, Isfahan, Iran from 2014 to 2016. Data were collected by a demographic questionnaire and the Newborn Breastfeeding Behaviors Tool completed by the researcher as she observed the newborns during breastfeeding after birth. The data were analyzed by one-way ANOVA, chi-square test and Kruskal-Wallis test in SPSS 20. RESULTS: There was no significant difference between demographic characteristics of the studied groups (P>0.05). In addition, there was significant difference in breastfeeding behaviors between groups. More clearly, breastfeeding ability was higher in the infants of the women administered with no drug than those of the women in the group (P=0.000). CONCLUSION: Physicians, nurses, and midwives can be informed about the side effects of the drugs used in labor on the newborns' breastfeeding, and improve their breastfeeding outcomes by decreasing the dose of used drug and the duration of the women's treatment with these drugs.

ABSTRACT

Introduction: A child afflicted with facial deformities such as cleft lip and palate usually affects their parents, because of difficulties in nutrition, speech, aesthetics and social connections, and also imposing a lot of stress on them. The aim of this study was to investigate the effects of a happiness program on the perceived stress in the mothers of children with cleft lip and palate. Methods: This study was a quasi-experimental study in which 64 mothers of children with cleft lip and palate were divided by simple random sampling into intervention and control groups (n=64). The program of happiness training was implemented within 10 sessions and the questionnaires of demographics and Cohen perceived stress were filled out prior to and two months after the last session in intervention group. Data analysis was done using SPSS Ver.13. Results: Independent t-test indicated a significant difference in the perceived stress mean score after training in the intervention and control groups. Also paired t-test indicated a significant difference in perceived stress mean score before and after training in the intervention group, but the difference was not statistically significant for the control group. Conclusion: Considering the effect of happiness program on reducing stress in the mothers of children with cleft lip and palate, it is recommended that this model can be used as an intervention in the maternal care for more involvement in the process of treatment and care of their child, in addition to reduce psychological problems in the parents.

ABSTRACT

INTRODUCTION: Facial deformities and aesthetic and functional anomalies in children may be a cause of real distress in families. Problems faced by parents in coping with a child's anomaly can be upsetting and lead parents to exhibit over-severe behavior. The present study was conducted in order to study the effect of happiness program on the happiness of the mothers of children with a cleft lip and palate. MATERIALS AND METHODS: In this semi-experimental study, 64 mothers of children with a cleft lip and palate enrolled by convenience random sampling were assigned to an intervention or control group based on a simple random sampling. Then, a program of happiness training was implemented consisting of 10 sessions of 2 hours each. A demographic questionnaire and the Oxford Happiness Questionnaire were completed prior to and 2 months after the last session of intervention. The data were analyzed using descriptive and analytical statistics, consisting of a paired t-test, independent t-test and Chi-square test using SPSS version 20. RESULTS: The independent t-test indicated a significant difference in mean happiness score after training between the intervention and control groups (P<0.05). Moreover, the paired t-test indicated a significant difference in mean happiness score between before and after training in the intervention group, although the difference was not statistically significant for the control group (P>0.05). CONCLUSION: In light of the efficacy of happiness training on the promotion of happiness in the mothers of children with a cleft lip and palate, this model is recommended as a healthcare intervention to decrease stress in mothers following the birth of an infant with a cleft lip and palate.

ABSTRACT

BACKGROUND: Incidence of asthma in adolescents leads to variations in family status, roles and interaction with peers for them, which could be a source of stress and psychological tensions in them. Therefore, the present study was conducted to investigate the effect of Orem's self-care model on perceived stress in adolescents with asthma. METHODS: In this semi-experimental study conducted from April 2013 to February 2014, 64 asthmatic adolescents referring Shariati Hospital, Isfahan were enrolled by simple random sampling and the patients were assigned to two groups of control and intervention. Then, Orem's self-care model-based training was implemented throughout eight sessions of two hours each and the Cohen Perceived Stress Scale was administered to both groups prior to and two months after the completion of the training. The data were analyzed by descriptive and analytical statistics consisting of paired t-test, independent t-test, Chi-square and Mann-Whitney using SPSS Version 20. RESULTS: Mean age of the participants was 14.15±3.12 years in the intervention group and 15.21±3.09 years in the control groups. 68.8% and 59.4% of the participants were male in the intervention and control groups, respectively. Independent t-test indicated a significant difference in the mean scores of perceived stress in the intervention (25.46±5.31) and control groups (28.90±5.27) after the training. Also, the result of paired t-test indicated a significant difference in the mean score of perceived stress between before (29.18±5.27) and after (25.46±5.31) training. CONCLUSION: As the training based on Orem's model had a positive effect on declining perceived stress in asthmatic adolescents, continuation of using these training interventions could contribute to ultimately achieving positive outcomes in health functions of these patients.

ABSTRACT

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a chronic disease which is accompanied with hopelessness and loss of the sense of well-being due to its symptoms and treatment. It also affects patients' sense of social and spiritual well-being. This disorder decreases patients' self-esteem and their quality of life by changing their mental image and self-confidence. This study was performed to find the relationship between self-esteem and quality of life of patients with ITP. SUBJECTS AND METHODS: This was a descriptive-analytical study on 64 patients with ITP who referred to Isfahan's Sayed Al-Shohada Hospital, Iran. In this study, patients with ITP were selected randomly using a random number chart. The data collection tools consisted of the World Health Organization Quality of Life (WHOQOL)-BREF and Coopersmith Self-esteem Inventory (CSEI). Data were analyzed using SPSS and chi-square and Mann-Whitney tests and the Pearson and Spearman's rank correlation coefficients. RESULTS: In total, 64 patients completed the questionnaires. RESULTS showed that 32% of subjects were over 36 years of age and 59% were women. In addition, 29.7% of ITP patients had low self-esteem and quality of life. Chi-square test showed a significant relationship between self-esteem and quality of life of patients with ITP. CONCLUSIONS: The results of the present study showed that considerable attention must be paid to self-esteem, as one of the most important factors influencing the promotion of quality of life. Therefore, it is suggested that patient's self-esteem be improved by the implementation of educational and psychological programs in order to decrease the consequences of poor quality of life.

ABSTRACT

BACKGROUND: Mental stress and daily crises comprise a part of physical and mental threats. Perceived stress is a physical and mental threat, as well. Perceived stress is a psychological process during which the individual considers his/ her physical and psychological welfare as being threatened. Since idiopathic thrombocytopenic purpura (ITP) is one of the chronic diseases being able to affect patients' perceived stress, this study was conducted to compare perceived stress in ITP patients and healthy people. MATERIALS AND METHODS: This is a descriptive-comparative study with control and case groups. In this study, 64 ITP patients referring Seyed Al-Shohada Hospital and the same number of healthy individuals from the patients' neighborhood, as the control group, were selected randomly and compared. The Kohen Perceived Stress Standard Questionnaire was used to collect the data. The data were analyzed by SPSS and Student's independent t-test, chi-square, and Mann-Whitney test. Results : 64.1%, 59.4% and 53.1% of participants in case group were older than 35 years old, female and had elementary education. 78.1% of case group had severe perceived stress. 70.3% of participants in control group experienced mild perceived stress. Mann-Whitney test showed significant difference between two groups in level of stress (p<0.001). CONCLUSION: In ITP patients, perceived stress was considerable. Planning interventional measures to determine stress-making agents and subside or at least control them is very essential.

ABSTRACT

INTRODUCTION: Acquisition of chronic diseases such as asthma leads to psychological, mental and physical complications in adolescents, and hence their self-esteem may be compromised. Therefore, the present study was conducted to assess the effect of Orem's self-care model on self-esteem of adolescents with asthma. MATERIALS AND METHODS: This semi-experimental study enrolled 64 asthmatic adolescents referred to Shariati Hospital, Isfahan. Subjects were assigned to two groups of control and intervention consecutively. Then, the self-care training program was conducted according to Orem's self-care model in eight two-hour sessions based on self-care needs, and self-esteem was measured in the two groups prior to and two months after the last training session. The data were collected by a questionnaire of demographic characteristics and the Coopersmith Self-Esteem Inventories (CSEI) and analyzed by SPSS version 20. RESULTS: Independent t-test showed a significant difference in the mean score of self-esteem between the intervention and control groups after the training (P<0.05), but the difference was not statistically significant prior to the intervention. Paired t-test showed a significant difference in the mean score of self-esteem before and after the training in the intervention group (P<0.01), but this difference was not statistically significant in the control group (P>0.05). CONCLUSION: Regarding the effect of Orem's self-care model on self-esteem of adolescents with asthma, we recommend the use of this model as a care intervention in healthcare centers to promote adolescents' health.
