Öğe Chronic intracerebroventricular apelin-13 infusion in rats increases daily food intake and body weight by reducing leptin levels(Wiley-Blackwell, 2014) Sandal, S.; Tekin, S.; Yilmaz, B.[Abstract Not Available]Öğe Comparison of exfoliated human mammary cells count with demographical and nutritional parameters of lactating mothers(Wiley-Blackwell, 2014) Agus, S.; Dinc, S. E.; Apaydin, A.; Sandal, S.; Vitrinel, A.; Yilmaz, B.[Abstract Not Available]Öğe Evaluation of estrogenic effects of polychlorinated biphenyls and organochlorinated pesticides using immature rat uterotrophic assay(Sage Publications Ltd, 2013) Uslu, U.; Sandal, S.; Cumbul, A.; Yildiz, S.; Aydin, M.; Yilmaz, B.In this study, we investigated the effects of polychlorinated biphenyls (PCBs) and organochlorinated pesticides on the serum levels of luteinising hormone (LH), follicle stimulating hormone (FSH) and weights and histomorphometry of uterine tissue in immature female rats using uterotrophic assay. A total of 36 rats were randomly divided into six groups (n = 6 per group) as control, oestradiol (E-2, 100 mu g/kg), PCB 180, Aroclor 1221, endosulfan and mirex at 10 mg/kg dosage. After 3 days of injections (subcutaneous), animals were decapitated and blood samples were collected. Uteri were dissected, weighed out and then fixed in 10% formaldehyde. They were processed for histomorphometry. The serum levels of LH and FSH were determined by enzyme immunoassay. Uterine weight was significantly increased by E-2 and reduced by mirex (p < 0.001 and p < 0.05, respectively). Total volume of uterus was significantly raised by E-2, Aroclor 1221 and endosulfan compared with that of the control group (p < 0.01). The ratio of epithelium was significantly increased by E-2, PCBs and pesticides (p < 0.01). The uterine cavity ratio was decreased by aroclor (p < 0.01), PCB 180 and mirex (p < 0.05). The serum levels of LH did not significantly differ among the groups but the levels of FSH were decreased by PCB 180 and endosulfan (p < 0.05 and p < 0.01, respectively). These findings suggest that PCB 180, Aroclor 1221 and endosulfan may be estrogenic in immature uterotrophic assay.Öğe Factors affecting industrial wood, material production yield in Turkey's natural beech forests(Editura Silvica, 2014) Atik, A.; Yilmaz, B.The objectives of the present study are to determine the most important factors affecting industrial wood material production yield in natural oriental beech forests in Turkey using a multifaceted approach and to help entrepreneurs consider these factors to develop more sensitive and realistic production plans. In Gunye Forest Management in Bartin province of the West Black Sea Region of Turkey, 41 production units were chosen as the study area. The 1277 ha study area was included in the 2007 and 2010 production management plan. The general state of the stand, natural stand structure, and production methods and tools are the factors thought most strongly affect industrial wood material production yield; 26 variables representing these factors were evaluated in the study. Through multidimensional statistical analyses, including main components, factor and regression analysis, we found that the most important factors affecting production yield were fertility, aspect of land, skidding method, stand structure, skidding distance, growing stock, transportation and harmful abiotic factors. Production units were divided into three groups based on yield rates and the 26 variables, using discriminate analysis. From the results of the study, a sample model can be developed to help forest managers predict and plan annual industrial wood production more sensitively and realistically.Öğe LANDSCAPE CHARACTERISTICS OF BATTALGAZI ARCHAEOLOGICAL AND HISTORICAL SETTLEMENT IN MALATYA, TURKEY, ITS PROTECTION PROBLEMS AND SOLUTIONS(Scibulcom Ltd, 2014) Yilmaz, B.; Saricam, S.; Aslan, F.; Atik, A.Historical settlements are the values which combine past and today, achieve interaction between cultures and give identity to the environment. It is usual in historical settlements that a change may be experienced. It is required that a prospective management and protection approach should be provided in order to avoid identity losses by experienced changes in historical settlements. Unfortunately, in time these values are eroded inside the uniform unplanned and distorted urban areas. It is emphasised in the 1972 UNESCO Convention for The Protection of The World Cultural and Natural Heritage that these unique cultural values belong not only to the geography they take place but also to human kind. It is a responsibility for human kind that these values should be protected in a complementary approach without isolating historical places form their original natural and cultural environment. Dating back to Palaeolithic period the Battalgazi town (Old Malatya) in Malatya city was researched. From the antique ages to date, this province has been one of the most important junction points which connect Middle East, Anatolia and Eurasia. In the Ottoman period; during the western attack of Ottoman Army local people were obliged to move orchards houses and set up today urban structure. The town Battalgazi survives with its historical and archaeological tissue. Historical tissue in the town is shaded by distorted urban area, destroyed by wrong restoration methods and poor maintenance conditions in addition to unsuitable socio-cultural structure. This study was carried out by scanning literature, interviewing responsible institutions and experts and evaluating data obtained from observations. In the study elements forming the historical tissue in the area were briefly identified and the relation between historical building and its environment, its land-use and landscape characteristics were investigated. Consequently, the degree of change and its effect on the town were determined.Öğe SUSTAINABLE USE OF AGRICULTURAL LANDS IN THE SCOPE OF URBAN AGRICULTURE: THE SAMPLE OF MALATYA, TURKEY(Scibulcom Ltd, 2016) Yilmaz, B.; Dogan, D.; Ates, O.; Cengiz, S.; Gormus, S.Agriculture is a strategically very important sector for every country since it supplies all vital food elements people need, meets the raw material demands of national industries, offers job opportunities to people from every levels of society and inputs foreign currency to national economy by exporting crops. However, it is one of the most affected sectors by the increasing urbanisation impacts due to rapid human population increase, improving socio-economic conditions and advancing technology. The province of Malatya located in Eastern Anatolia region of Turkey meets nearly 80% of world dried apricot need. Urban agriculture lands taking place in urban tissue of Malatya city and composed mainly of apricot orchards (AO) have been lost at an important rate for the last 15 years. From this point of view, in the scope of the present study, land cover (LC) and land use (LU) types were determined first to determine the rate of lands lost to the use types other than agriculture. The rate of the areas gained and lost was determined by investigating the changes in these LC/LU types between 1984 and 2014. Protective and improving strategies were developed by determining socioeconomic and legal and administrative reasons for the lost agricultural lands (AL) and AO.
