Transgender people and those who have an undifferentiated gender identity face various personal and social challenges due to their dissatisfaction with the gender role and the desire to behave differently from the gender role. Thus, focusing on this group of people is one of the issues in health and psychology. To this end, the present study aimed to explore more deeply the challenges and problems faced by this group of people. This qualitative study was conducted based on the grounded theory proposed by Corbin and Strauss on 15 members of social networks and the Association of People with Gender Dissatisfaction. The participants were selected through purposive sampling from among those with undifferentiated gender identities from childhood to adulthood. The data were collected via individual in-depth interviews with the participants. The collected data were analyzed using the systematic grounded theory approach to extract related categories and codes and develop a conceptual model. The analysis of the data revealed 54 themes that were grouped into 9 subcategories and 5 main categories. Gender affirming was extracted as the core phenomenon. The causal factors included the feeling of living in another person’s body and problems in social relationships. Contextual factors were divided into 4 subcategories including family challenges, positive and negative public reactions, peer relationship problems, and economic challenges. The intervening factors were school problems and the role of media. In addition, the consequences were the positive and negative experiences of life in another body. Finally, the extracted strategies were support and individual coping strategies. Social factors and family and school play an important role in aggravating the problems of people with gender dissatisfaction. Focusing on empowering these people can help them adopt effective coping strategies. Besides, given the lack of recognition for people with gender dissatisfaction, raising public awareness of the challenges faced by these people is particularly important.

Jaundice is one of the most common diseases of the infancy period. It could be caused by different factors, including infections such as the urinary tract. The present study aims to evaluate the prevalence and causes of urinary tract infection in newborns.

The present work is a cross-sectional study conducted on 100 newborns with jaundice hospitalized at the neonatal ward of the Pasteur Hospital of Bam or referred to its outpatient clinic. Participants were selected through convenient sampling. Besides the routine tests for jaundice, a urine sample was also taken from the newborns for culturing and evaluating urinary tract infection. After collecting the data, they were analyzed using the chi-square and t-tests.

According to the results, 41 (41%) of the newborns were girls, and 59 of them (59%) were boys. The prevalence of urinary tract infection among newborns with jaundice was 27%. The most common cause of infection was Escherichia Coli, and the rate of infection was lower among newborns breastfed compared to those fed by infant formula (p<0/05).

The most common risk factors for neonatal jaundice were prematurity, blood type incompatibilities, delivery problems, and decreased breastfeeding. Given that one of the most important causes of long-term jaundice is a urinary tract infection, it may appear before other symptoms.

Occupational burnout has numerous psychological consequences affecting social capital. Similarly, social capital is one of the most important factors affecting occupational burnout. Thus, the present study is conducted to investigate the relationship between social capital with occupational stress and burnout among the staff of Rafsanjan University of Medical Sciences.

In this descriptive-correlational study done in 2016, 156 subjects were selected based on the inclusion criteria through a random sampling method. For data collection, the researchers applied Vilanova and Chosachr('39')s Social Capital Questionnaire, Occupational Stress Questionnaire (provided by HSE), and Occupational Burnout Questionnaire (Maslach, 1981). The data were analyzed using Pearsonchr('39')s Correlation Coefficient and Regression Test.

The study indicated that, there was no link between social capital with occupational stress and burnout by demographic characteristics except experience. The results indicated that social capital had a significant negative association (0.01) with occupational stress and burnout. Moreover, a significant negative association (0.01) was observed between the aspects of social capital and occupational burnout.

The results showed that social capital had a significant and negative association with occupational stress and burnout; occupational stress and burnout can predict the social capital of staff.

This research was conducted to investigate the effect of salinity stress due to increased sodium chloride on some morphological and physiological characteristics in rootstocks and interspecific hybrids of pistachio and screening of tolerant rootstocks. The factorial experiment in a completely randomized design was carried out in greenhouse conditions. The factors included four rootstocks (Badami-Riz-e-Zarand, Ghazvini, and interspecific hybrids Integerrima × Badami-Riz-e-Zarand, Integerrima × Ghazvini) and three salinity levels (0, 100 and 200 mM of NaCl) with three replicates in coco peat and perlite media. The results showed that with increasing salinity level, stem height, leaves numbers, leaf area, leaf fresh and dry weight, stem fresh and dry weight, root fresh and dry weight, leaf relative water content, leaf potassium and the ratio of potassium to sodium decreased, and ionic leakage, proline, and leaf sodium increased. The highest stem height was observed in Integerrima × Ghazvini hybrid. In addition, the highest leaves numbers, leaf area, leaf fresh and dry weight, stem fresh and dry weight, root fresh and dry weight, leaf relative water content, leaf proline content, leaf potassium and the ratio of potassium to sodium were observed in Ghazvini rootstock and the lowest was related to Integerrima × Badami-Riz-e-Zarand hybrid. The most amount of leaf ionic leakage and sodium concentration of leaves were observed in Integerrima × Badami-Riz-e-Zarand hybrid. It seems that Ghazvini and Integerrima × Ghazvini hybrid are more tolerant and Integerrima × Badami-Riz-e-Zarand hybrid is more sensitive to salinity stress.

Cold is an environmental factor limiting the growth and yield of agricultural crops. To find cold-tolerant pistachio rootstocks, a factorial experiment was conducted at Pistachio Research Center (PRC), Rafsanjan, Iran during 2017-2018. The factors included six rootstocks (Badami Zarand, Ghazvini, Sarakhs, Integerrima × Badami Zarand, Integerrima × Ghazvini and Integerrima × Sarakhs) and four thermal treatments (4, 0, -2, and -4°C) with three iterations. Seedlings in 6-8 leaf stage were placed in thermal treatments for two hours. Ionic leakage, pH of leaked solution, chlorophyll fluorescence, photosynthesis efficiency index, chlorophyll (a, b, total) and carotenoid contents were the traits assessed in this study. Based on the results, a decrease in temperature made an increase in ionic leakage rate, conversely making decreases in pH of the leaked solution, photosynthetic pigments contents, Fv/Fm and PI index. In addition, the highest photosynthetic pigments, pH of leaked solution, Fv/Fm and PI index were observed in Ghazvini and Integerrima × Ghazvini rootstocks. Meanwhile, the highest ionic leakage was observed in Integerrima × Badami Zarand. In aggregate, Ghazvini and Integerrima × Ghazvini were identified as the most cold-tolerant rootstocks, while Integerrima × Badami Zarand was the most cold-sensitive rootstock.
