    The present study examines the relationships between defeat, entrapment, suicidal ideation, thwarted belongingness, and perceived burdensomeness through the Integrated Motivational-Volitional (IMV) Model of Suicidal Behaviour in a sample of Turkish young adults. The sample consisted of 451 individuals (72.5% females, Mage= 25.20). The correlation analyses revealed significant relationships between defeat, entrapment, suicidal ideation, thwarted belongingness, perceived burdensomeness in the expected directions. Mediation and moderation analyses partly confirmed the assumptions of the motivational phase of the IMV model; entrapment played a mediating role between defeat and suicidal ideation, and thwarted belongingness (but not perceived burdensomeness) had a moderating role in the pathway between entrapment and suicidal ideation. These findings add a new dimension to the understanding of suicide risk and potential protective factors through the IMV model, which was tested for the first time in the Turkish population. It is anticipated that this study will contribute to suicide prevention intervention strategies, especially for young adults, at-risk group for suicide in Turkey

    Bu tez çalÄ±ĆŸmasında desfluran ve sevofluranın, diyabet oluƟturulan ratların hiperglisemi döneminde beyin dokusu oksidan antioksidan sistem ĂŒzerine etkilerinin araƟtırılması amaçlanmÄ±ĆŸtır. Wistar Albino cinsi 30 adet rat rastgele Kontrol, Diyabet kontrol, Diyabet, Diyabet-Desfluran ve Diyabet- Sevofluran olarak 5 gruba ayrıldılar. Diyabet gruplarına 55 mg/kg streptozotosin uygulandı. Kan Ɵekeri 250 mg/dl ve ĂŒzerinde olanlar diyabetik olarak kabul edildi. Diyabet grubuna 2.5 g/kg glikoz uygulandı. Sevofluran ve Desfluran gruplarına anestezi uygulamasından önce 2.5 g/kg glikoz uygulandı ve 2 saat boyunca minimum alveoler konsantrasyon 1 olacak Ɵekilde, desfluran %6, sevofluran %2,3 oranında 4 L/dk oksijen ile karÄ±ĆŸÄ±m halinde uygulandı. 100 mg/kg ketamin enjeksiyonu ardından ratlar sakrifiye edildi. Ötenazi sonrasında beyin dokusu alınarak soğuk 0.154 M NaCl çözeltisi ile yıkanarak -80 ÂșC de muhafaza edildi. Beyin dokuları homojenize edilerek sĂŒpernatanlarda CAT, GST, PON aktiviteleri ile TBARS seviyeleri ölĂ§ĂŒldĂŒ. Diyabet kontrol grubu CAT, GST ve PON aktiviteleri ile TBARS seviyesi kontrol grubuna göre azalmÄ±ĆŸ olarak bulundu, ancak bu azalma istatistiksel olarak anlamsızdı. Desfluran grubu CAT, GST ve PON aktiviteleri ile TBARS seviyesi kontrol grubuna göre azalmÄ±ĆŸ olarak bulundu, bunlardan yalnız CAT ve PON aktivitelerindeki azalma istatistiksel olarak anlamlıydı (p<0.05). Sevofluran grubunda ise CAT, GST ve PON aktiviteleri ile TBARS seviyesi kontrol grubuna göre dĂŒĆŸĂŒk olarak bulundu, CAT aktivitesindeki azalma istatistiksel olarak anlamlıydı (p<0.05). Diyabet-desfluran ve Diyabetsevofluran gruplarında ise CAT, GST, PON aktiviteleri ve TBARS değerlerinde kontrol grubuna göre azalmalar görĂŒldĂŒ. Ayrıca, diyabet oluƟturulan ratlarda, desfluran ve sevofluran uygulamasında, sevofluran uygulamasının desfluran uygulamasına göre antioksidan sistemi daha az etkilediği görĂŒlmektedir. Bu etkinin ise desfluranın kimyasal yapısından kaynaklandığı dĂŒĆŸĂŒnĂŒlebilir.The purpose of this study was to determine the effects of sevoflurane and desflurane on oxidantantioxidant system in diabetic rats brain tissue in temporary hyperglycemia period. 30 Wistar Albino rats were divided randomly into 5 groups: Control, Diabetic control, Diabetic, Diabeticdesflurane and Diabetic-sevoflurane. Diabet induced by streptozotocin at a dose of 55 mg/ kg. Rats were classified as diabetic if their blood glucose levels exceed 250 mg/dl. We injected 2,5 g/kg glucose on diabetic group and before the anesthetic exposure to sevoflurane and desflurane groups. We administered 6% desflurane and 2% sevoflurane mixtured by 4L/min oxygen during 2 hours. All rats received ketamin 100 mg/kg and and then we took out these rats brain and measured levels of CAT, GST, PON enzyme activities and TBARS levels in brain tissue. In group Diabetic Control, CAT, GST and PON enzyme activities and TBARS level less than control group but these results were not statistically significant. In group Desflurane, CAT, GST, PON activities and TBARS level less than control group but only CAT and PON activities were statistically significant. In addition to in group Sevoflurane, CAT, GST, PON activities and TBARS level less than control group but only CAT activity was statistically significant. We determined that CAT, GST, PON activities and TBARS levels decrease when desflurane and sevoflurane administered on hyperglycemic diabetic rats. Desflurane is more harmfull than sevoflurane on brain antioxidant system in hyperglycemia period of diabetic rats. We think this harmful effects source from the chemical structure of desflurane

    The aim of this study is to examine the non-routine problem posing skills of pre-service physics teachers and determine which metacognitive strategies they use. The research was conducted according to qualitative research methods. In this context, the findings were reached by analyzing the content of the data. Data on the knowledge and opinions of a total of 40 pre-service teachers studying in 1st, 2nd, 3rd and 4th grades on problem posing and non-routine problem posing according to grade levels were collected at the beginning of the study. Later, the non-routine problem posing activity was applied to 20 candidates who were randomly selected from among the pre-service teachers. In this way, data were collected about the problem posing skills of 20 randomly selected pre-service teachers and their metacognitive strategies when setting up non-routine problems. According to the results of the study, it was seen that the physics teacher candidates had knowledge about non-routine problems and problem posing approach .However, they did not have experience with problem-posing approach in physics teaching. One of the results obtained in the study is that teacher candidates are metacognitively active while setting up non-routine problem situations. After the non-routine problem posing activity, the preservice teachers expressed positive opinions about the use of the problem posing approach in physics education. In line with the results obtained, suggestions were made to include problem posing activities in physics education and to conduct academic studies in the branch of physics education in universities. Keywords: physics teacher candidates, creative thinking, problem solving, non-routine problem posing, metacognitive strategies.Öz İçinde bulunduğumuz yĂŒzyılda yaratıcı dĂŒĆŸĂŒnme ve problem çözme becerileri oldukça önem kazanmÄ±ĆŸtır.

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P &lt; 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
