Article Citation - WoS: 3Citation - Scopus: 3The Role of Honor Concerns in Disclosing (vs. Hiding) COVID-19 Diagnosis: Insights from Turkiye(Springer/plenum Publishers, 2023) Ceylan-Batur, Suzan; Dogulu, Canay; Akbas, Gulcin; Yet, Barbaros; Uskul, Ayse K. K.Members of honor cultures value engaging in moral behaviors and managing their social image to maintain their honor. These two goals reflect reputation and integrity concerns, which also have bearing on gender roles. In the current study, we examined a) evaluations of women and men described as diagnosed with COVID-19 and as either hiding or disclosing their diagnosis, b) the moderating role of honor concerns (reputation and integrity) and the gender of the infected person in these evaluations, and c) the relationship between honor concerns and individuals' own disclosure preferences among participants living in Turkiye, a country that exemplifies an honor culture. Findings revealed that participants with stronger reputation concerns evaluated a woman's hiding behavior more favorably than that of a man's. Moreover, higher integrity concerns were associated with lower levels of participants' own preference to hide a diagnosis for both men and women, whereas reputation concerns were positively associated with a preference for hiding a diagnosis among men only. Furthermore, a content analysis of participants' open-ended explanations of their views on women's and men's motivation to hide a diagnosis revealed further evidence for the gendered nature of reputation concerns. Our findings point to the importance of prioritizing integrity concerns (and downplaying reputation concerns) in public health campaigns in honor cultures.Article Citation - WoS: 6Citation - Scopus: 6Does Overparenting Hurt Working Turkish Mother's Well-Being? the Influence of Family-Work Conflict and Perceived Stress in Established Adulthood(Springer/plenum Publishers, 2023) Aydin, Eren Miski; Metin-Orta, Irem; Metin-Camgoz, Selin; Aksan, NazanAlthough extant research demonstrates the negative impact of overparenting on child well-being, there remains a paucity of evidence on the effect of overparenting on the parents' own well-being. The purpose of this study is to investigate the effects of overparenting on parental well-being, and to explore the mechanisms through which overparenting influences the well-being of working mothers, particularly among established adults. Thus, we examined the serial mediation effects of perceived stress and family-to-work conflict (FWC) in overparenting and well-being linkage. With this aim, the data were collected from working mothers (N = 258) aged between 30 and 45, a period of in their lifespan generally characterized by efforts devoted to career and care. Via serial mediation analyses, the findings postulate that (a) overparenting relates to the well-being and perceived stress of working mothers, (b) perceived stress (both individually and jointly with FWC) mediates the relationship between overparenting and well-being, and (c) perceived stress and FWC serially mediate the association between overparenting and well-being. The findings provide evidence related to the well-being experiences of established adulthood women in struggling their career-and care crunch from a perspective of overparenting, stress, and family-to-work conflict.Article Citation - WoS: 5Citation - Scopus: 3The Roles of Intrusive Visual Imagery and Verbal Thoughts in Pre-Sleep Arousal of Patients With Insomnia Disorder: a Path Model(Springer/plenum Publishers, 2023) Turkarslan, Kutlu Kagan; Cinarbas, Deniz Canel; Perogamvros, LamprosPurpose Researchers have proposed that multiple factors such as hyperarousal, conditioning, worrying, or cortical arousal play roles in the predisposition to, initiation, and perpetuation of insomnia disorder. Previously, only a few studies investigated the differential effects of intrusive visual imagery (IVI) and intrusive verbal thoughts (IVT) on pre-sleep arousal or insomnia severity. The aim of the current cross-sectional study was to examine these effects as well as the moderator role of visual imagery ability (VIA) on the relationship between IVI and pre-sleep arousal.Methods A path model comprising the variables of IVI, IVT, pre-sleep arousal, and insomnia severity was tested with 166 of 1444 participants (M-age = 25.5, SD = 5.26) who were identified as having insomnia disorder based on a 12-question form corresponding to DSM-5 criteria for insomnia disorder and Insomnia Severity Index scores (>= 8). The moderator role of VIA on the relationship between IVI and pre-sleep arousal was evaluated with a moderation analysis.Results It was found that IVI (beta = 0.44, p < .001), but not IVT (beta = 0.15, p = .12), significantly predicted pre-sleep arousal and pre-sleep arousal (beta = 0.44, p < .001) significantly predicted insomnia severity. In addition, the indirect effect of IVI via pre-sleep arousal (IE = 0.19, p < .001) on insomnia severity was significant. Finally, the moderator role of VIA on the relationship between IVI and pre-sleep arousal (p = .07) was not significant.Conclusions IVI may play a more important role in insomnia disorder than IVT. Interventions targeting pre-sleep visual imagery can help poor sleepers alleviate insomnia severity.Publication The Roles of Intrusive Visual Imagery and Verbal Thoughts in Pre-Sleep Arousal of Patients With Insomnia Disorder: a Path Model ( Oct , 2023 , 10.1007/S10608-023-10442-0)(Springer/plenum Publishers, 2024) Turkarslan, Kutlu Kagan; Cinarbas, Deniz Canel; Perogamvros, Lampros[No Abstract Available]Article Citation - WoS: 14Citation - Scopus: 15Leptin Promotes Proliferation of Neonatal Mouse Stem/Progenitor Spermatogonia(Springer/plenum Publishers, 2020) Yersal, Nilgun; Kose, Sevil; Horzum, Utku; Ozkavukcu, Sinan; Orwig, Kyle E.; Korkusuz, PetekPurpose To keep and increase spermatogonial stem cell number (SSC) is the only available option for pediatric cancer survivors to maintain fertility. Leptin is secreted by the epididymal white adipose tissue and has receptors on stem/progenitor spermatogonia. The purpose of this study is to demonstrate dose- and time-dependent proliferative effect of leptin on stem/progenitor spermatogonia cultures from prepubertal mice testes. Methods CD90.2 (+) stem/progenitor spermatogonia were isolated from the C57BL/6 mouse testis on postnatal day 6 and placed in culture. The proliferative effect of leptin supplementation was assessed by colony formation (diameter and number), WST proliferation assays, and xCELLigence real-time cell analysis (RTCA) on days 3, 5, and 7 of culture. Expressions of p-ERK1/2, p-STAT3, total STAT3, and p-SHP2 levels were determined by western blot analysis. Results Leptin supplementation of 100 ng/ml increased the diameter (p= 0.001) and number (p= 0.01) of colonies in stem/progenitor spermatogonial cultures and caused higher proliferation by WST-1 (p= 0.009) compared with the control on day 7. The EC50 was calculated as 114 ng/ml for leptin by RTCA. Proliferative dose of leptin induced increased expression of p-ERK1/2 (p= 0.009) and p-STAT3 (p= 0.023) on stem/progenitor spermatogonia when compared with the untreated group. Conclusion The results indicated that leptin supplementation exhibited a dose- and time-dependent proliferative effect on stem/progenitor spermatogonia that was associated with increased expression of ERK1/2 and STAT3 pathways while maintaining their undifferentiated state. This output presents a new agent that may help to expand the stem/progenitor spermatogonia pool from the neonatal testis in order to autotransplant after cancer treatment.
