The Opinions Of Student-Teachers On The Science Teaching Based On Multiple Intelligence Theory
Hüsnüye DURMAZ
Journal of Turkish Science Education , 2005,
Abstract: The purpose of this study is to define the student-teachers’ multiple intelligence fields, their opinions about the applicability of the theory in science teaching, about the positive or negative aspects of the science teaching based on the theory, and finally, about the feasibility of the theory, which might be a part of student centered teaching approach during teaching.
Investigation of Attitudes of Students in The Programs of Class Teaching, and Science Teaching Towards Chemistry Lesson, and The Relation Between Their Multiple Intelligence Fields and Their Success in Chemistry and Language Lessons
Journal of Kirsehir Education Faculty , 2005,
Abstract: The basis of Multiple Intelligence Theory contains development and learning during life time. According to this theory all human have different intelligences which are verbal-linguistic, logical-mathematical, visual-spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal and naturalist intelligences in varying amounts.In this study, the attitude toward Chemistry Lesson, the Multiple Intelligence Fields of the 1st class students in the program of Class Teaching and Science Teaching at Trakya University, Faculty of Education, and the relation between their attitudes, their multiple intelligence fields and their success in Chemistry and Turkish Language Lessons were investigated.In order to find out the intelligence fields of students the inventory of multiple intelligence taken from Saban (2002) was used. And the chemistry lesson attitude scale developed by Morgil etc. (2000) was utilized to establish their attitudes toward chemistry lesson.The data obtained were evaluated in SPSS 11.0 package program, and variation analysis, t-test and correlation analyses for all data were applied.As a result of research it was found that students were positive in their attitude toward chemistry lesson and their intelligence fields were expanded through developed medium-level as homogenous to all intelligence fields.The significant differences were found out between students’ intelligence fields regarding their main branches., and a relationship existed between students’ attitude toward chemistry lesson and their logical/mathematical and verbal/linguistic of intelligence fields, and between students’ success in chemistry lesson and logical/ mathematical field of intelligence.

Journal of Food Technology , 2013,
Abstract: This study was carried out to examine the influence of dietary humic acid on the oxidative status in liver, meat and eggs of quail. A total of 260 Japanese quails, one week of age, were randomly assigned to one control and three experimental groups. The quails were fed with a basal diet (H0), the basal diet supplemented with 360 mg kg 1 (H1), 480 mg kg 1 (H2) or 600 mg kg 1 (H3) humic acid. After 9 weeks of feeding, the all quails were slaughtered. Liver, meat and eggs were analyzed for antioxidant and oxidant parameters. Liver samples of H1, H2 and H3 groups showed a higher degree of oxidant parameters (indicated by a lower antioxidative capacity) than those of H0 samples. However, the antioxidant and oxidant parameters in the meat and eggs samples were not affected by adding humic acid. Our findings indicated safety of humic acid for meat and eggs of quail and support the use of humic acid as a food additive.
Effect of Ripening Time on Mineral Contents of Herby Cheese

Journal of Animal and Veterinary Advances , 2012,
Abstract: Herby cheese is a salted traditional cheese manufactured in the Eastern and South-eastern of Turkey. Its name, herby, comes from adding herb in cheese. The aim of this study was to assess the changes in the mineral contents and some chemical parameters in herby cheese during 90 days of ripening. The total solids, ash, salt, Na, Cu, Fe, Mn contents and pH values increased significantly (p<0.05), while Ca, Mg and Zn contents decreased significantly (p<0.05) during ripening. P, Co, Cr, Ni and Cd contents of the cheeses were not significantly (p>0.05) altered during ripening. The results indicated that the mineral of herby cheese showed a very variable behaviour during ripening due to likely manufacturing technology.
Antibacterial activities of Allium vineale, Chaerophyllum macropodum and Prangos ferulacea

African Journal of Biotechnology , 2006,
Abstract: Allium vineale L., Chaerophyllum macropodum Boiss. and Prangos ferulacea (L.) Lindl. have been used for cheese production in Turkiye for many centuries. In addition, it is traditionally believed by local people that these plants have antibacterial activity. The purpose of this study was to evaluate the antibacterial activity of these plants. Four solvent extracts (in methanol, ethanol, n-hexane and water) of the plants were investigated against Bacillus cereus, Bacillus subtilis, Micrococcus luteus, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella enteritidis and Salmonella typhimurium by using disc diffusion method. The methanol, ethanol and nhexane extracts of all the plants showed antibacterial activity against B. cereus, B. subtilis, M. luteus and S. aureus, while the methanol extract of Allium vineale was also active against P. mirabilis. However, the water extracts of these plants had no antibacterial activity against any of the bacteria tested. The methanol extracts had the higher activity followed by the extracts of ethanol and n-hexane. A. vineale showed the higher antibacterial activity as compared with C. macropodum and P. ferulacea. As a result, organic solvent extracts (especially methanol and ethanol extracts) of these plants can be used as natural antibacterial additives for incorporation in cheese and various food products.

Morphology Of Cultured Cells Of Glioblastoma Multiforme
Ramazan DURMAZ
Journal of Neurological Sciences , 2007,
Abstract: The aim of the present study is to asses the morphology of cultured glioblastoma multiforme cells obtained from five patients. Established tissue cultures of malignant astrocytoma cells showed polymorphic characters phenotypically. There were various types of tumor cells including ovoid cytoplasm with multiple processes, elongated unipolar and bipolar, spindle, bizarre in shape, and large flat cell as well as multinucleated gigantic form. As the passage of the tissue culture of glioblastoma multiforme continued, their cell morphology became more similar in appearance. In the present study, the glioblastoma multiforme cells in vitro included heterogeneous subpopulations of tumor cells, which may explain why the treatment modalities remain insufficient in clinics.

Turkish Journal of Urology , 2011,
Abstract: Objective: This study aimed to determine VHL gene mutations and the relation of these mutations to type and pathological stage of renal tumors.Materials and methods: Forty patients (20 males, 20 females; mean age 59 years) who underwent ablative surgery for renal tumor prediagnosis between February 2009-November 2009 in of Ege University School of Medicine, Department of Urology were randomly selected. Twenty-nine of the patients underwent radical nephrectomy, 5 underwent partial nephrectomy, and 2 patients underwent laparoscopic radical nephrectomy. Four patients whose pathological outcome was not malign kidney tumor have been excluded from the study. Thirty-eight patients (21 males, 16 females; mean age 61 years) who underwent any surgeries in Department of Urology and showed no malignance suspicion in the same time period were included in control group. VHL gen mutations were analyzed preoperatively. Results: According to 2002 TNM staging, 8 (22%) patients were T1a, 11 (31%) patients were T1b, 3 (8%) patients were T2, 9 (25%) patients were T3a, 3 (8%) patients were T3b, and 2 (6%) patients were T4 stage. Twenty-eight (78%) patients were N0, 5 (14%) patients were N1, and 3 (8%) patients were N2. Five (14%) patients was at M1 stage. Histologically, 18 (50%) patients had clear cell carcinoma, 3 (8.3%) patients had chromofob cell carcinoma, and 3 (8.3%) patients had papillary cell type 1 carcinoma. Genetic analysis showed that 6 individuals had heterozygote change described previously as mutation (Q167Q and V181V linked heterozygote in 2 patients, P61P heterozygote in 2 patients, L129L heterozygote in 1 patient, and P61P heterozygote in 1 patient). None of these changes resulted in the change of aminoacids.Conclusion: VHL gene mutation was not detected in our study population, which may be result of the genetical characteristics of Turkish population or small sample size. The present study would be a pioneer for future studies on tumor tissue and VHL gene polymorphism in Turkish population.
