SCIENCE CURRICULUM FROM THE PERSPECTIVES OF TURKISH TEACHERS: PROBLEMS ENCOUNTERED AND SUGGESTIONS FOR SOLUTIONS

The purpose of this research is to identify the problems that teachers have experienced during the implementation of the science curriculum and their suggestions for solution to these problems. In the research, survey model has been used among the descriptive research methods in which quantitative and qualitative data have been used together. The sample of the research consists of science teachers (n=208) and classroom teachers who deliver science courses (n=104) in Manisa province. A questionnaire form and a semi-structured interview form developed by the researchers have been used as data collection tools. For quantitative data, percentage and frequency values have been analysed and for qualitative data, content analysis have been performed. As a result of the analyses the problems encountered in the implementation of the curriculum have been examined in three different categories namely; teacher-related problems, curriculum-related problems and other problems. According to the results of the questionnaire, most of the teachers think that they confront with problems because they do not see themselves sufficient in terms of designing/evaluating a project, designing an experiment and creating an activity. In terms of the program, the majority of teachers think that they encounter with problems as there is not enough information about the implementation of the inquiry-based learning approach and not enough examples and explanations for the learning outcomes. In addition, nearly half of the teachers’ state that they have problems with the use of alternative assessment tools and techniques in the program. Regarding other problems; the insufficient content of the course book, lack of materials, lack of adequate support from parents, and technological inadequacies are among the problems most of the teachers have experienced. Similarly, when the results of interviews have been examined; materials, laboratories, and the inadequacy of the course book are among the most frequently mentioned problems. When the survey results of teachers' suggestions for solution have been examined; putting more emphasis on teachers’ views in the process of curriculum development, revision of curricula of education faculties oriented to the changes in curriculum, preparation of flexible curricula according to students’ needs, improvement of technological infrastructure of schools and classes, preparation of guidebooks for teachers, raising the knowledge levels of parents about the instruction program, providing an in-service training for designing experiments/projects are among the most frequently selected recommendations from teachers. When the interview results have been examined, it has been seen that most of the suggestions are about increasing the number and quality of in-service trainings and increasing the quality of laboratory and material facilities and textbooks. Since the newly announced science curriculum will be gradually implemented as of 2017-2018 academic year, it is expected that the results of the study will contribute to the field in terms of the problems and solution suggestions for the current curriculum, the program development and update studies, the contents of in-service trainings and comparison of the curricula.  Article visualizations

Musculoskeletal Pain, Related Factors, and Posture Profiles Among Adolescents: A Cross-Sectional Study From Turkey

Purpose: The aim of the study was to evaluate musculoskeletal pain due to mechanical reasons and related risk factors in adolescents and to define posture profiles of adolescents. Design: A cross-sectional study. Methods: The study was conducted with 2221 adolescents between February 2015 and May 2015. The questionnaire used to collect data consisted of three parts: (1) descriptive characteristics of the participants, (2) pain assessment of 14 parts of the body, and (3) Back Pain and Body Posture Evaluation Instrument (BackPEI). Results: The prevalence of low back pain among the participants was 73.3% (n = 1,343), while the prevalence of back pain was 68.4% (n = 1,254). The participants attributed their pain to their poor sitting postures at school (38.1%, n = 847) and carrying school backpacks (84.1%, n = 1,713). There was a statistically significant difference in the physical activities of adolescents and the BackPEI score (z = 4.40; p = .001). Posture factors of the BackPEI score increased while school desk comfort score increased (Spearman's rho = 0.148; p = .001), but it decreased while the school grades of the adolescents increased (Spearman's rho [ρ] = −0.161; p = .001). Conclusions: According to this study, body posture was related to musculoskeletal pain and was correlated with physical activities, school desk comfort, and school grades of the adolescents. It is suggested that correct posture and ergonomic positions should be taught to adolescents when using computers, carrying school backpacks, and sitting in school chairs to prevent musculoskeletal pain. © 2020 American Society for Pain Management Nursin

Epilepsy in vacuolating megalencephalic leukoencephalopathy with subcortical cysts

AbstractVacuolating megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a disorder characterised by acquired macrocephaly, developmental motor delay of varying degrees, slowly progressive cerebellar and pyramidal signs, and initially preserved intellectual function. More than 60% of the published cases had epileptic seizures.In this study, we analysed the seizures and EEG findings of nine patients with MLC. Six patients (66.6%) with moderate to severe neurological impairment had epilepsy, four with partial and two with generalised seizures. The EEG of five epileptic patients revealed epileptogenic foci over the temporal, frontal and parietal regions with variable predominance during waking and sleep. The facilitation of spike-and-wave paroxysms by eye closure, by intermittent photic stimulation and by hyperventilation were determined in four patients. Four patients also showed abnormalities in the background activity. In conclusion, we think that epilepsy is a significant component of MLC compared to the other leukodystrophies. The elucidation of the underlying molecular defect may explain the unusual pathogenetic relation between this leukoencephalopathy and the associated seizures

Hepatoprotective potential of chestnut bee pollen on carbon tetrachloride-induced hepatic damages in rats

This study was supported by Research Fund of Karadeniz Technical University (Project no. 2009.111.002.5). Two of the authors, Oktay Yildiz and Huseyin Sahin, were funded by TUBITAK-BIDEB for their graduate studies.Bee pollen has been used as an apitherapy agent for several centuries to treat burns, wounds, gastrointestinal disorders, and various other diseases. The aim of our study was to investigate the hepatoprotective effects of chestnut bee pollen against carbon tetrachloride (CCI4)-induced liver damage. Total phenolic content, flavonoid, ferric reducing/antioxidant power, and DPPH radical activity measurements were used as antioxidant capacity determinants of the pollen. The study was conducted in rats as seven groups. Two different concentrations of chestnut bee pollens (200 and 400 mg/kg/day) were given orally and one group was administered with silibinin (50 mg/kg/day, i.p.) for seven days to the rats following the CCI4 treatment. The protective effect of the bee pollen was monitored by aspartate transaminase (AST) and alanine transaminase (AST) activities, histopathological imaging, and antioxidant parameters from the blood and liver samples of the rats. The results were compared with the silibinin-treated and untreated groups. We detected that CCI4 treatment induced liver damage and both the bee pollen and silibinin-treated groups reversed the damage; however, silibinin caused significant weight loss and mortality due, severe diarrhea in the rats. The chestnut pollen had showed 28.87 mg GAE/g DW of total phenolic substance, 8.07 mg QUE/g DW of total flavonoid, 92.71 mg Cyn-3-glu/kg DW of total anthocyanins, and 9 mg beta-carotene/100 g DW of total carotenoid and substantial amount of antioxidant power according to FRAP and DPPH activity. The results demonstrated that the chestnut bee pollen protects the hepatocytes from the oxidative stress and promotes the healing of the liver damage induced by CCI4 toxicity. Our findings suggest that chestnut bee pollen can be used as a safe alternative to the silibinin in the treatment of liver injuries

The effect of white tea on serum TNF-α/NF-κB and immunohistochemical parameters in cisplatin-related renal dysfunction in female rats

The study was funded by a grant from the scientific research foundation of Recep Tayyip Erdogan University .Objective: Nephrotoxicity is the most important side effect of the antineoplastic drug cisplatin, thereby restricting its use. The aim of this study was to investigate the protective effects of white tea infusions (WT) against renal damage induced by cisplatin (CP) in rats by biochemical and histopathological means. Materials and methods: This study used 24 female Sprague Dawley rats at 12–14 weeks of age and weighing 250–300 g. Rats were divided into three groups: Control, CP and CP + WT groups. CP was injected 7 mg/kg i.p as a single dose/rat in the CP group. White tea was given at a dose of 0.5% (w/v) for 4 weeks. At the end of the experiment, blood urea nitrogen (BUN), creatinine, uric acid, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and nuclear factor kappa B (NF-κB) along with caspase-3 in the kidney were evaluated in study. Results: BUN, creatinine, TNF-α NF-κB and IL-6 levels of the CP group showed a statisically significant increase in comparison to the control group. TNF-α NF-κB and IL-6 levels showed a statistically significant decrease in the CP + WT group with respect to the CP group. Caspase-3 levels in tubular epithelial cells decreased in CP + WT group compared with CP group (p = 0.02). Conclusion: White tea infusions reduced significantly the nephrotoxicity of CP. The anti-nephrotoxic feature of the infusion may be attributed primarily to its anti-inflammatory and anti-apoptotic characteristics

Effects of geraniol on anxiety/depression-like behavior and hippocampal cholinergic system in rats

Amaç: Kronik stresin depresyon benzeri davranışları arttırdığı bilinmektedir. Geraniol nöromodülatör ve antidepresan etkileri bilinen doğal bir monoterpendir. Bu çalışma, kronik kısıtlama stresi depresyon modeli sıçanlarda geraniolun kolinerjik sistem üzerine olası etkilerini araştırmak için tasarlanmıştır. Gereç ve Yöntem: Çalışmada erişkin 21 adet dişi sıçan kullanıldı. Sıçanlara 3 hafta süreyle günde 5 saat kısıtlama stresi uygulandı. Geraniol oral gavaj yoluyla 100 mg/kg uygulandı. Stres ve ilaç uygulamalarını takiben açık alan testi ile anksiyete, zorunlu yüzme testi ile depresyon benzeri davranışlar değerlendirildi. Daha sonra sıçanlar ötenazi edilerek hipokampus disekte edildi. Asetilkolin (ACh) ve asetilkolinesteraz (AChE) düzeyleri hipokampal doku homojenatlarında ELISA yöntemi ile belirlendi. Bulgular: Stres maruziyeti anksiyete benzeri davranışı belirgin olarak etkilemedi ancak zorunlu yüzme testlerinde depresyon benzeri davranış parametrelerini uyardı. Geraniolun strese bağlı artan hareketsizlik süresini önemli ölçüde azalttığı tespit edildi (p<0.05). Dahası, stres maruziyeti ve geraniol uygulamasının hipomkampal ACh düzeylerini anlamlı olarak etkilemediği gözlemlendi (p>0.05). Diğer yandan, kronik stres AChE düzeylerini önemli ölçüde azalttı (p<0.05). Geraniol tedavisinin AChE düzeylerini belirgin olarak değiştirmediği tespit edildi (p>0.05). Sonuç: Birlikte ele alındığında, bulgularımız kısıtlama stresinin sıçanlarda depresyon benzeri davranışı uyardığı, geraniol tedavisinin ise antidepresan benzeri etkilerini ortaya koydu. Bununla birlikte, geraniolun antidepresan benzeri etkisinin moleküler mekanizmasının ileri çalışmalarla araştırılmasını öneriyoruz.Objective: It is known that chronic stress increases depression-like behaviors. Geraniol is a natural monoterpene known for its neuromodulatory and antidepressant effects. This study was designed to investigate the possible effects of geraniol on the cholinergic system in chronic restraint stress depression model rats. Materials and Methods: 21 adult female rats were used in the study. Restraint stress was applied to rats for 5 hours a day for 3 weeks. Geraniol was administered at 100 mg/kg by oral gavage. Anxiety was evaluated with the open field test, and depression-like behaviors were evaluated with the forced swimming test following stress and drug administration. Then the rats were euthanized and the hippocampus was dissected. Acetylcholine (ACh) and acetylcholinesterase (AChE) levels were determined in hippocampal tissue homogenates by ELISA method. Results: Stress exposure did not significantly affect anxiety-like behavior, but it stimulated depression-like behavior parameters in forced swimming tests. It was determined that geraniol significantly decreased the increased immobility time due to stress (p<0.05). Moreover, it was observed that stress exposure and geraniol administration did not significantly affect hippocampal ACh levels (p>0.05). On the other hand, chronic stress significantly decreased AChE levels (p<0.05). Geraniol treatment did not significantly change AChE levels (p>0.05). Conclusion: Taken together, our findings revealed that restraint stress induces depression-like behavior in rats, while geraniol treatment has antidepressant-like effects. However, we suggest that the molecular mechanism of the antidepressant-like effect of geraniol be investigated with further studies

Oral skuamoz hücreli karsinoma: 5 Olgu sunumu

Amaç: Oral Sukuamoz Hücreli Karsinoma (SHK) farklı klinik belirtilerle tanımlanan malign bir tümördür. Oral SHK’nın ilk belirtileri genellikle asemptomatik ülser ya da ağrısız şişlik görünümüdür. 40 yaş üzeri erkeklerde görülme olasılığı daha fazladır. Tütün ve alkol kullanımı SHK için geleneksel olarak kabul gören en büyük risk faktörüdür. Erken evre SHK hastalarının çoğu ilk olarak diş hekimleri tarafından görülmektedir. Bu nedenle, diş hekimleri tüm hastalarda oral muayene yaparken, ülseratif / eroziv lezyonlara daha fazla dikkat etmelidir. Bu çalışmanın amacı SHK’nın klinik belirtilerini değerlendirmektir.Olgu Tanımlaması: Bu çalışmada farklı tutulum bölgelerinde oral SHK olan beş hasta sunuldu. Tüm olgularda ortak bulgu ilk semptom olarak ağrısız şişliğin varlığıydı.Bulgular: Beş hastanın üç tanesi kadın, iki tanesi erkektir. Yaşları 29 ve 84 arasında değişmektedir. Bölge dağılımı alveoler sırt (2), bukkal mukoza (2), ağız tabanı (1) şeklindedir. Hastaların hiçbirisinde alkol ve sigara kullanımı bulunmamaktadır.Sonuç: SHK başlangıçta ağrısız şişlik olarak ortaya çıkabilen ağız boşluğunu etkileyen en yaygın malign neoplazmdır. SHK’lar en çok 40 yaş üzeri hastalarda görülür fakat 20 li ve 30lu yaşlarda gençlerde de hastalığın tanısı konulabilmektedir. Tütün ve alkol kullanımı gibi geleneksel risk faktörleriyle ilişki olmadığı zaman SHK gelişimi için diğer olası risk faktörlerini göz önünde bulundurmak önemlidir.ANAHTAR KELİMELEREtiyoloji, oral kanser, skuomöz hücreli karsinom &nbsp
