Social and emotional learning (SEL): How it finds a place in an early childhood education curriculum in Turkey

The study aims to identify the Social and Emotional Learning (SEL) skills as defined by Collaborative, Academic, Social and Emotional Learning (CASEL) in the Turkish Early Childhood Education Curriculum (TECEC). Recent studies have pointed out that gaining SEL skills at early ages has many benefits for development. Researchers in the SEL area suggest that having a clear conceptual framework benefits both in research and practice. TECEC document is examined based on CASEL’s framework. Document analysis was used to identify how SEL standards and objectives in TECEC were conceptually designed. The findings show that out of 17 standards to support social and emotional development, only 10 of them are related to SEL, meanwhile, 7 of them are identified as social studies standards. Out of 53 stated objectives, thirty-one of them are related to SEL skills. The current study will provide a tool for researchers, curriculum developers, and practitioners that feel the need to base their research and practice on a solid conceptual framework

Usporedba kemijskih i bioloških značajki propolisa pčelinje pasmine Apis mellifera caucasica iz turskih provincija Ardahana i Erzuruma

The aim of this study was to compare the biological activities of ethanolic propolis extracts of Apis mellifera caucasica obtained from Ardahan and Erzurum provinces of Turkey. Samples were tested for antioxidant, anticytotoxic, anticarcinogenic, antibacterial, and antifungal potentials using different techniques. Propolis samples from the two provinces had different mineral and organic compositions related to their geographical origin. The ferric reducing antioxidant power (FRAP) test showed superiority of Ardahan propolis over the Erzurum. Regardless of origin and the presence of mitomycin C in the culture medium, propolis enhanced human peripheral lymphocyte viability, which depended on the duration and propolis concentration. Antiperoxidative activity on MCF-7 breast cancer cells was concentrationdependent. Erzurum propolis showed the highest anticarcinogenic activity at the concentrations of 62.5 μg/mL and 125 μg/ mL, which dropped at higher concentrations. All propolis samples also showed antibacterial activity against the tested human pathogens similar to ampicillin and penicillin controls, except for Pseudomonas aeruginosa. However, they did not exert any antifungal activity against Candida albicans and Yarrowia lipolytica. In conclusion, propolis samples from both provinces showed promising biological activities, but further research should focus on finding the right concentrations for optimal effect and include the cell necrosis pathway to get a better idea of the anticarcinogenic effects.Cilj je ovoga istraživanja bio usporediti biološku aktivnost etanolnih ekstrakata propolisa pčelinje pasmine Apis mellifera caucasica iz dviju turskih provincija: Ardahana i Erzuruma. Testirana su njihova antioksidacijska, anticitotoksična, antikancerogena, antibakterijska i antifungalna svojstva. Uzorci iz tih dviju provincija razlikovali su se u mineralnom i organskom sastavu koji je odražavao njihovo zemljopisno podrijetlo. Test redukcije željeza/antioksidacijske snage (engl. ferric reducing antioxidant power, krat. FRAP) otkrio je superiornost ardahanskoga propolisa nad erzurumskim, no bez obzira na podrijetlo i prisutnost mitomicina C u mediju, oba su propolisa povećala vijabilnost ljudskih perifernih limfocita, a učinak je ovisio o koncentraciji i trajanju. Propolis iz Erzuruma iskazao je najveću antikancerogenu aktivnost u koncentracijama od 62,5 i 125 μg/mL, no ona se smanjila s višim koncentracijama. Oba su propolisa također iskazala antibakterijsku aktivnost sličnu ampicilinskoj i penicilinskoj kontroli, osim kad se radilo o bakteriji Pseudomonas aeruginosa. Međutim, oba su zakazala protiv plijesni Candida albicans i Yarrowia lipolytica. Može se zaključiti da uzorci propolisa iz obiju provincija pružaju obećavajuće biološke aktivnosti, no u daljnja istraživanja, koja se trebaju usmjeriti na traženje optimalnih koncentracija za postizanje željenog učinka, treba uključiti i nekrotični put u mehanizmu djelovanja kako bi se stekao bolji uvid u njihovo antikancerogeno djelovanje

The Immunohistochemical Evaluation of Kidney An Experimentally Induced Hypertensive And Diabetic Rat Model

AMAÇ: Bu çalışmada, deneysel olarak ayrı ayrı ve birlikte diyabet ve hipertansiyon modeli oluşturulan sıçanlarda, lipoik asidin hipertansif ve diyabetik böbrek üzerindeki tedavi edici/hasar önleyici etkisinin araştırılması amaçlandı. YÖNTEMLER: Çalışmamızda Wistar cinsi ratlar 8 gruba ayrıldı (n=7). I. grup; Kontrol, II. Grup; Diabetes Mellitus, III. grup; 5/6 Nefrektomi, IV. Grup; Lipoik asit, V. Grup; 5/6 Nefrektomi+Diyabet, VI. grup, Diyabet+Lipoik asit VII. Grup; 5/6 Nefrektomi+Lipoik asit ve VIII. Grup; 5/6Nefrektomi+Diyabet+Lipoik asit. Diyabet modeli 45mg/kg STZ enjeksiyonu ile oluşturuldu ve hipertansiyon modeli için 5/6 nefrektomi modeli uygulandı. dl-α-Lipoik asit 30mg/kg/gün olacak şekilde 8 hafta oral gavaj yöntemi ile deneklere uygulandı. Böbrek dokuları rutin ışık mikroskobik doku takip işlemlerinden geçirilip parafin bloklara gömüldü. İmmünohistokimyasal olarak AT1 (Anjiyotensin II tip I reseptörü), VEGF (Vasküler Endotelial Büyüme Faktörü) ve ET1 (Endotelin 1) antikorları işaretlendi. BULGULAR: Diyabet ve nefrektomi modellerinin ayrı ayrı ve birlikte uygulandığı deneysel gruplarda (Grup 2, 3, 5), glomerüloskleroz, mononükleer hücre infiltrasyonu, intersitisiyel fibrozis, damarlarda ve tübüllerde dilatasyon ve hiyalin materyal birikimi ile tübüler yapıların dejenerasyonu gözlendi. Aynı gruplarda tübülointersitisiyel ve glomerüler AT1 azalırken, VEGF ve ET1 artış göstermişti. Lipoik asit tedavi gruplarında ise AT1'de artış, VEGF ve ET1'de ise Kontrol ve Lipoik asit grubuna benzer şekilde azalma gözlendi. SONUÇ: Diyabet ve hipertansiyonun birlikte gözlenmesinin böbrek hasarının hızlı ilerlemesine neden olduğu, lipoik asidin bu hastalıklara karşı böbrek üzerinde tedavi edici etkisinin olduğu sonucuna varıldı. OBJECTIVE: In this study, experimental diabetes and nephrectomy have been applied separately and together in order to investigate possible therapeutic/damage prevention effects of Lipoic acid on hypertensive and diabetic rat kidneys. METHODS: Wistar rats were divided into 8 groups (n=7); Group 1; Control, Group 2; Diabetes Mellitus, Group 3; 5/6 Nephrectomy, Group 4; Diabetes Mellitus+5/6 Nephrectomy, Group 5; Lipoic acid administration, Group 6; Diabetes Mellitus+Lipoic acid, Group 7; 5/6 Nephrectomy+Lipoic acid, Group 8; Diabetes Mellitus+5/6 Nephrectomy+Lipoic acid groups respectively. Diabetes was formed by 45mg/kg STZ injection and for hypertension nephrectomy 5/6 model was applied. dl-α-Lipoic acid 30mg/kg/day was fed by oral gavage for 8 weeks. Kidney tissues were embedded into paraffin block after routine light microscopic preparation. AT1 (Angiotensinojen II type 1 receptor), VEGF (Vascular Endothelial Growth Factor) and ET1 (Endothelin) antibodies were labelled immunohistochemically in same group. RESULTS: In groups where diyabetes and nephrectomy were applied separately and together, glomerulosclerosis, mononuclear cell infiltration, interstitial fibrosis, vascular and tubular dilatation and hyalin deposition and degeneration of tubular structures were seen in glomerules. In the same group: tubulointerstitial and glomerular AT1 was decreased but VEGF and ET1 were increased. In Lipoic acid treatment groups, AT1 was increased and VEFG and ET1 were decreased similar to Control and Lipoic acid group. CONCLUSION: We have come to the conclusion that diabetes nd hypertension together increases the rate of renal injury and lipoic acid has therapeutic effect on kidney
