    Anatomy of the cervical canal in the Angora Goat (Capra hircus)
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2010) Dayan, Mustafa Orhun; Besoluk, Kamil; Eken, Emrullah; Ozkadif, Sema
    This study was performed to reveal the anatomy of the cervical canal in Angora goats. For this purpose, sixty genital tracts of adult Angora goats in estrus, weighing from 40 to 50 kg, obtained from Konya slaughterhouses, were used. The materials were examined by dissection and latex cast techniques. In dissections, the vaginal protrusions were star, duckbill, crescent, spiral, cluster and bump-shaped. In the materials with latex cast and dissection, because the circular folds were of high volumes in the caudal half of the cervical canal, the blind sacs were deeper than those of the cranial half. Based on the latex cast, we have noticed with interest that the cervical canal had a convexity in dorsal direction because its cranial and caudal thirds were curved ventrally. It was concluded that the anatomical structure of the cervical canal mentioned in this study might be considered in intrauterine catheter applications in Angora goats.

    The biometric ratios on the tarsus of the chinchilla (chinchilla lanigera) based on 3d reconstructed images
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2019) Ozkadif, Sema; Eken, Emrullah; Haligur, Ayse
    This study was undertaken to perform a three-dimensional (3D) reconstruction of the tarsal bones of chinchillas using multidetector computed tomography (MDCT) images and reveal biometric ratio of the bones and compare between sexes. For this purpose, a total of 12 adult chinchillas (Chinchilla lanigera) of both sexes (six males and six females) were used. After anesthetizing the animals, MDCT images were obtained in DICOM format, and 3D reconstruction was performed on a computer using the Mimics 13.1 program. The volumes and surface areas of each of the bones that constitute the tarsus of the chinchilla were automatically measured by the program based on the 3D model. After all values of each tarsal bone were expressed as ratios with in tarsus, they were analyzed statistically to reveal differences between sexes. The results showed that there were statistical differences (P<0.05) in calcaneus, talus, central tarsal bone and tarsal bone IV in term of volume ratio and in central tarsal bone, tarsal bone I and tarsal bone IV in term of surface area ratio between sexes. It is considered that 3D tarsus models are useful in revealing anatomic structures and also in assisting clinical diagnosis and treatment.

    Morphometric evaluation of chinchillas (chinchilla lanigera) femur with different modelling techniques
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2016) Ozkadif, Sema; Varlik, Abdullah; Kalayci, Ibrahim; Eken, Emrullah
    Together with technological developments, different methods in anatomic and morphometric studies have been started to be used. In fact, in this study, more than one method was used and the reliability of these methods was presented. This study was performed in the aim of getting 3D model with three dimensional (3D) reconstruction and photogrammetric methods obtained from multidetector computerized tomography (MDCT) images of femur of chinchilla by mimics program, comparing the data of both methods and presenting whether there was a difference between genders as well as left and right sides. For this purpose, 6 chinchillas of both sexes were used. First of all, MDCT images of animals were taken under general anaesthesia and 3D reconstruction was obtained after transferring the data to personal computer as DICOM format. After taking MDCT images, the femurs of the animals killed by the conventional methods were cleaned of muscle and fats by boiling and their 3D models was formed by using images via photogrammetric methods. The measurements were taken from the models of two methods and volume and surface area of femur were found significant at a level of p< 0.05 as a result of statistical processes. According to this, a statistically difference was not found in morphometric measurement values except volume and surface area. Moreover, while a statistical difference was not found between right and left femur of both sexes, a difference was determined between sexes and it was observed that the measurement values of females were higher than males. As a result, since 3D models obtained by both methods had almost same values, it was considered that these methods could be used in anatomic and morphometric studies.

    The suggested metaphors regarding on the concept of "cell" by teacher candidates of biology, science and primary
    (ELSEVIER SCIENCE BV, 2010) Yener, Yesim; Ozkadif, Sema
    The main purpose of this study is to define the perceptions of biology, science and primary teaching candidates studying at Selcuk University on the concept of "cell" using metaphors. The data of the study was obtained through the answers given to the complete-questions such as "cell is like...because,..." and "cell is similar to..., because..." The suggested metaphors were gathered under 6 groups: "administrative", "controller", "building stone", "information store", "cooperative", "connective". As a result, it was seen that almost two third of the participants defined cell as "building stone" and "cooperative" while the rest, one third, defined it as "administrative","controller", "information store" and "connective". The results of this study indicate important data on the fact that metaphors can be used as effective tools to reveal the students' personal perceptions on the concept of cell. (C) 2010 Elsevier Ltd.

    Three- dimensional reconstruction of the thorax in the mongoose (Herpestes ichneumon)
    (AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2018) Ozkadif, Sema; Haligur, Ayse; Eken, Emrullah
    Three- dimensional (3D) reconstruction obtained by using multidetector computed tomography (MDCT) images have widely been used in anatomical studies. Thorax is one of the most important body cavities necessary for the protection of lungs and heart in mammals Two adult mongooses (1 male, 1 female) obtained from traffic accidents were used in this study. The images obtained from MDCT were stacked and 3D reconstruction of thorax was performed by overlaying images using a 3D modeling software (Mimics 13.1). Some measurements of thoracic cavity, lungs and sternum were taken from the reconstructive images of mongoose and indexes were calculated from these measurements. The morphometric parameters were recorded for both sexes. From the study, it could be concluded that the thoracic cavity, lungs and sternum imagings and findings revealed by 3D modeling techniques can be utilized for anatomical training of wild animals This study is expected to help in the diagnosis and treatment of thorax diseases in wild animals.

    Three-dimensional reconstruction of multidetector computed tomography images of paranasal sinuses of New Zealand rabbits
    (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2013) Ozkadif, Sema; Eken, Emrullah
    This study was conducted to produce a 3-dimensional reconstruction using multidetector computed tomography (MDCT) images of the anatomic structures forming the paranasal sinuses of New Zealand rabbits and to present biometric properties of the sinuses and conchae. A total of 16 adult New Zealand rabbits, comprising 8 males and 8 females, were included in the study. After high-resolution MDCT images of the paranasal sinuses were obtained, they were reconstructed using a 3-dimensional modeling program (Mimics) by overlapping the images and the biometric measurements of the structures forming the paranasal sinuses. The maxillary sinuses of New Zealand rabbits were made up of 2 compartments. It was also observed that their conchae were more developed with an uneven structure. The frontal sinus and sphenoid sinus were not seen and the ethmoid sinus was not observed. There was not a significant statistical difference between sinus and conchae constituting the right and left paranasal sinuses of the same sex; however, a significant statistical difference was observed between the sexes (P < 0.05). This study's data can be used for purposes of modern anatomy education and research and may form a basis as a model for future studies to be performed on the paranasal sinuses.
