    Education methods to be used in the emotional, mental and psychological development of instrument education are of great importance in terms of education process. In this context, the training habits and self-efficacy developments of the students with their instruments can be supported by the accompaniment education process, thus increasing the performance of the instruments. In this context, an experimental method was used in the research by using piano accompaniment training practice, individual instrument training habits and instrument performance self-efficacy belief questionnaires. Pre-test-posttest pattern of this method was preferred. The study was carried out with 9 students who studied flute in Nevsehir Hacı Bektas Veli University music department. After the experiment process, the scores of the groups were reached by using Ttest. As a result of the research, it was revealed that the application of piano accompaniment in flute education has a positive effect on all sub-dimensions of both questionnaires. In addition, it was determined that students use time in a disciplined and productive way, develop themselves in terms of musicality, see themselves more adequate with the positive progress of the psychological effects of this development, and increase their love for their instrument and desire to work

    In this study, AISI 1040 and AISI 4140 steels were boriding using Ekabor-II commercial boriding powder with powder-pack boriding method using microwave and conventional heating methods. The samples were borided at 950 °C for 2 and 6 hours in an Ar atmosphere in a microwave oven of Enerzi-Mh2912-V8. Biphasic structure (FeB/Fe2B) was formed in all borided AISI 4140 samples and AISI 1040 samples borided for 6 hours. A single-phase structure was observed in AISI 1040 steel borided for 2 hours. Compared to the conventional method, a 1.5-1.6 times thicker boride layer was obtained in AISI 4140 and AISI 1040 steels with microwave-assisted powder-pack boriding. The highest hardness was measured as 1561.8 HV0.05 for boriding AISI 4140 steel and 1499.7 HV0.05 for boriding AISI 1040 steel. The Vickers indentation fracture toughness of borided steels with microwave energy varied between 2.31 and 3.46 MPa·m1/2. It was determined that in all samples borided by the microwave-assisted and conventional powder-pack boriding method, the adhesion strength between the boride layers and the substrate obtained was sufficient

    Gençliği belirleyen yaş aralıkları çeşitli çalışmalarda ve uluslararası kurumlar tarafından farklılaşabilmektedir. Bu tanımlar içerisinde Birleşmiş Milletler'in genç tanımı en çok kabul görenidir ve 15-24 yaş arasını kapsamaktadır. Bu yaş aralığı, gençlerin eğitim aşamalarının sonu ve hayata atılma yaşlarının başlarıdır. Gençler aldıkları eğitim sırasında ve yetişkinlik öncesi süreçte, katılım başta olmak üzere toplumsal anlamda sorumluluklarının farkında olmalıdırlar. Diğer deyişle, gençlerin yetişkinlik öncesi dönemde okulda aldıkları eğitim ve kazandıkları bilinçle toplumsal konularda daha duyarlı hareket etmeleri ve görüşlerini rahatça ortaya koyabilmeleri beklenmektedir. Ancak bu farkındalık, tek başına eğitim öğretim kurumlarında kazanılacak bir gelişme değildir. Gençlerin katılımını arttırmak için genel anlamda merkezi- yerel yönetim ve sivil inisiyatif tarafından teşvik edilmeleri ve gençlere yönelik hazırlanacak programlarla katılım konusunda yönlendirilmeleri gerekmektedir.Bu çalışmada, gençliğin katılımıyla ilgili mevcut durum genel bir perspektiften değerlendirilmiş ve gençlerin katılımına etki eden unsurlar analiz edilmiştir. Bu kapsamda katılımla ilgili unsurlar değerlendirilirken, halka en yakın ve katılımına en uygun yönetim birimi olan yerel yönetimler düzeyindeki katılım ve uygulamalarına vurgu yapılmıştır.Definitions and the age ranges of youth differ in literature. Among these definitions, United Nations' definition is the most approved one. United Nations defined youth as, people between ages of 15-24. These ages are the end of education and the start of personal careers. During the education of young people and the period before adolescence, young people have to be aware of their social responsibilities. In other words, in this period young people have to be more responsive to social problems and expressive about their thoughts. This awareness cannot be learned only at schools. Young people have to be stimulated by local governments and civil initiatives to increase their participation. And also programs about youth participation have to be prepared.In this study, current situation about participation of young people is evaluated. And also factors effecting the participation of young people are analyzed. While the problem is evaluated in this content, participation in local governments is also emphasized

    Polymerization of resin-based materials leads to temperature rise, caused by the exothermic nature of the reaction and energy absorbed during polymerization. This temperature rise is influenced by intensity of light, composition of resins, and type of light source. This study evaluated thermal insulating properties of four photo-polymerizing pulp-capping agents in primary and permanent teeth. Roots of 80 primary and permanent teeth were removed. Class-I cavities were prepared on the occlusal surfaces of teeth. Materials used were TheraCal LC, Biner LC, ACTIVA BioACTIVE, and Calciplus LC and light sources were 3 M-Elipar and VALO LED. Temperature rise was measured using a J-type thermocouple. Data were statistically evaluated using ANOVA and Tukey`s tests (p = 0.05). VALO LED exhibited significantly lower temperature rise in all groups and temperature rise in primary teeth was significantly higher with all experimental materials (p < 0.05). The highest temperature change was observed in the Biner LC group (3.82 ± 0.58) and the lowest change in the Activa-BioACTIVE group (1.78 ± 0.34). The VALO LED light source caused a significantly lower increase in pulpal temperature compared with the 3 M-Elipar source. All tested materials and light sources maintained pulpal temperature under safe limits, with temperature increases not exceeding 5.5 °C

    Recurrent hydatidiform moles: detection of a new mutation in the NLRP7 gene in the family

    Get PDF
    Hydatidiform moles are the most common type of gestational trophoblastic neoplasia. Hyperproliferative vesicular trophoblasts and imperfect fetal development are abnormal pregnancies, and recurrent hydatidiform moles are rare. Mutations in NLRP7 are responsible for recurrent hydatidiform mole. Genetic heterogeneity has been demonstrated in patients with the NLRP7 mutation. This study presents our case with gravida 11, parity 0, histopathologically diagnosed with six hydatidiform moles and five missed abortion histories at age 35. Karyotype analyses of the unrelated couple were normal. A genetic examination revealed a novel mutation of the NLRP7 gene in the patient, his brother, and his parents. Detecting a new NLRP7 mutation in recurrent hydatidiform moles cases provides further evidence for the predetermined role of NLRP7 mutations in the pathophysiology of recurrent moles hydatidiform. Based on our findings, we hope to contribute to the literature by expanding the spectrum of recurrent pregnancy loss associated with NLRP7 mutations in patients

    Get PDF
    Background and aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global epidemic in T & uuml;rkiye and worldwide. The aim of this study was to evaluate the prevalence and predictors of MASLD and steatohepatitis among adults who died of unnatural causes including sudden death and non-burn trauma. Method: We conducted a prospective review of all consecutive adult forensic autopsies for natural (sudden unexpected) and non-natural (Suicidal, homicidal and accidental) suspicious deaths carried out at the Istanbul Council of Forensic Medicine from February to May 2022. Four wedge biopsies were extracted from sagittal sectioned liver specimens. A liver pathologist with 20 years of experience examined each case for steatosis, ballooning, inflammation, and fibrosis. Results: Among 1797 autopsies, 62 met inclusion criteria. Overall, 43.3 % (n = 26) of autopsies showed evidence of steatotic liver disease, with a distribution of steatosis severity as: Grade I (28.3 %), Grade II (6.6 %), and Grade III (8.3 %). All these cases met at least one cardiometabolic criteria and diagnosed with MASLD. Ballooning was observed in 20.0 % of cases (5 cases grades 1 and 7 cases grade 2), and Inflammation was present in 51.7 % (9 cases with grade 0-1, 12 with 1-2, 7 with 2-3, and 3 with 5-6). Notably, 46.1 % (n = 12) of MASLD cases and 20.0 % (n = 12) of all cases were diagnosed with steatohepatitis, with three cases exhibiting delicate perisinusoidal fibrosis and one case showing portal fibrosis. Conclusion: The histopathological findings from this autopsy study confirmed the markedly high prevalence of MASLD and steatohepatitis within the general adult population, highlighting the concerning burden of steatotic liver disease in T & uuml;rkiye

    PURPOSEThoracic endovascular aortic repair (TEVAR) is a safe and effective treatment method for a variety of thoracic aortic pathologies. We aimed to investigate the mortality and complication outcomes and associated factors of TEVAR treatment in Turkey.METHODSIn this single-centered retrospective study, patients with thoracic aorta pathologies treated with TEVAR at Gazi University School of Medicine, Department of Radiology, between January 2009 and January 2020 were included. Perioperative, early, and late mortality, complications, and technical success were the outcomes.RESULTSThe sample comprised 58 patients with 68 TEVAR interventions. Eleven (16.2%) patients were female, the mean age was 60.1 ± 13.4 years. Emergent TEVAR was required in 20.7% of the patients. The main indications of TEVAR were intact descending aorta aneurysms in 37.9% of the sample, 31.0% Stanford type-B dissection, and 12.1% traumatic transections. The technical success rate of primary and secondary interventions was 98.3% and 100%, respectively. The mortality rate in the first 30 days was 8.6%. Seventeen (29.3%) cases had at least 1 complication related to TEVAR treatment. The most common complication was type-1A endoleak (10.3%). Having acute symptoms, stroke, and acute renal failure were significantly associated with mortality (P=.020, .049, and .009, respectively).CONCLUSIONThis study reported the outcomes of TEVAR treatment from a tertiary medical center in Turkey over a decade. Patients presenting with acute symptoms and who developed stroke and acute renal failure after the procedure should be carefully followed up as these factors were found to be associated with mortality

    Hipertiroidizm tedavisinde yaygın olarak kullanılan metimazol, deneysel çalışmalarda geçici hipotiroidizm modeli oluşturmak için kullanılmaktadır. Çalışmamızda metimazol ile oluşturulan sıçan hipotiroidi modelinde kognitif fonksiyonların değerlendirilmesi ve hipotiroidinin anksiyete ve depresyon benzeri davranışlar üzerine etkisinin belirlenmesi amaçlanmıştır. Oniki adet erişkin dişi/erkek Wistar sıçan (250-300 g) iki gruba ayrılarak bir gruba 4 hafta süre ile içme suyu içinde %0,02 metimazol verilerek hipotiroidizm oluşturulmuş, diğer gruba normal içme suyu verilmiştir. Dört hafta sonunda, Morris su labirenti, yükseltilmiş artı labirent, kuyruk suspansiyon testi, pasif sakınma testi uygulanmıştır. Metimazol kesildikten 8 hafta sonra serum serbest T4 ve TSH düzeyleri ölçülmüş ve tiroid dokusu histopatolojik olarak değerlendirilmiştir. Morris su labirenti testinde sadece 1. günde gruplar arasında anlamlı fark izlenmiştir (p < 0,001). Pasif sakınma testinde ise gruplar arasında anlamlı fark görülmemiştir (p = 0,477). Yükseltilmiş artı labirentte hipotiroid sıçanlar açık alanda daha fazla süre geçirmiş (123,5 ± 35,5 sn vs. 12,5 ± 7,9 sn; p = 0,012); açık ve orta alana daha fazla sayıda giriş yapmıştır (sırasıyla, 3,0 ± 0,4 vs. 0,7 ± 0,5; p = 0,006, 6,2 ± 1,2 vs. 2,8 ± 0,7; p = 0,042). Kuyruk suspansiyon testinde hipotiroid grubun hareketsiz kaldığı süre, ötiroid gruba göre anlamlı olarak daha uzun bulunmuştur (186,2 ± 19,5 sn vs. 110,3 ± 26,2 sn; p = 0,043). Histopatolojik incelemede, hipotiroid grubunda kolloid vakuolizasyonu izlenmiş, ancak serum serbest T4 ve TSH düzeylerinde gruplar arasında fark görülmemiştir. Sonuç olarak, sıçanda metimazol hipotiroidi modeli öğrenme ve bellekte bozulma oluşturmaksızın, anksiyeteyi azaltıp depresyona eğilimi artırmaktadır. Bu zeminde, hipotiroidi ve kognitif fonksiyon ilişkisini aydınlatmaya yönelik ileri çalışmalar planlanmalıdır.Methimazole, a widely used agent in the treatment of hyperthyroidism, is also used to induce hypothyroidism in experimental studies. In this study, we aimed to evaluate cognitive functions and anxiety- and depression-like behaviours in a methimazole-induced rat hypothyroidism model. Twelve adult female/male Wistar rats (250-300 g) were randomly divided into two groups, one of which was given 0.02% methimazole in drinking water for 4 weeks, as the other group was given normal water. After 4 weeks, Morris water maze, elevated plus maze, tail suspension test, passive avoidance test was applied. Serum free T4 and TSH levels were measured 8 weeks after discontinuation of methimazole, and thyroid tissue was evaluated histopathologically. In the Morris water maze test, a significant difference was observed between the groups only on the 1st day (p < 0.001). There was no significant difference between the groups in the passive avoidance test (p = 0.477). In the elevated plus maze, hypothyroid rats spent more time in the open-field (123.5 ± 35.5 sec vs. 12.5 ± 7.9 sec; p = 0.012); made more entries into the open and middle area (3.0 ± 0.4 vs. 0.7 ± 0.5; p = 0.006 and 6.2 ± 1.2 vs. 2.8 ± 0.7; p = 0.042, respectively). In the tail suspension test, the duration of immobility was significantly longer in the hypothyroid group (186.2 ± 19.5 sec vs. 110.3 ± 26.2 sec; p = 0.043). In the histopathological examination, colloid vacuolization was observed in the hypothyroid group, but serum free T4 and TSH levels did not show difference between the groups. In conclusion, methimazole-induced hypothyroidism decreases anxiety and increases tendency to depression without impairing learning and memory. On this basis, further studies should be planned to elucidate the relationship between hypothyroidism and cognitive functions
