    Biomechanical comparison of the effects of the storage temperature on Tibiotarsus in Japanese quail
    (Bursa Uludağ Üniversitesi, 2021-12-18) Süzer, Bayram; Veteriner Fakültesi; Anatomi Ana Bilim Dalı; 0000-0002-2687-1221
    The study aimed to compare the effects of different cryopreservation temperatures on mechanical properties and determine the optimal cryopreservation temperature for bones in Japanese quail. Bone biomechanical tests are getting more attention but, fresh bones are not always available for testing and have a limited lifespan. Cryopreservation of biological specimens is often needed during tissue preparation and me- chanical testing. In the study, the tibiotarsi were collected from 8 weeks of age quail, and bones were divided into four groups of fresh bones; frozen at 0 o C, frozen at -20 o C, and frozen at -80 o C. Frozen bones were kept in the freezer for three weeks. After three weeks, bones were subjected to a three-point bending test for biomechanical evaluation. There was no significant difference between the mechanical strength properties of fresh tibiotarsi and the tibiotarsi stored in three different storage conditions of 0 o C, -20 o C, or -80 o C. It was observed that cryopreservation of tibiotarsi at 0, -20, and -80 °C for up to three weeks did not negatively affect bone biomechanical properties in quail.

    Functional forms of the muscle bundles belong to external eye muscles in human and sheep
    (Uludağ Üniversitesi, 2000-09-15) Yıldız, Bahri; Yıldız, Hüseyin; İkiz, İhsaniye; Veteriner Fakültesi; Anatomi Ana Bilim Dalı
    The superior (dorsal), lateral and medial rectus muscles from 5 adult humans and Kıvırcık sheeps were included in the study. Transversal sections of 5 micrometers in thickness from the venteria (middles) of the muscles embedded in paraffin were prepared by rutin method and examined under stereomicroscope at 4x2x10 magnification. The primary, secondary and tertiary fibre bundles from all of the muscles except the medial rectus muscle of human were obviously observed in the sections. The biggest and the smallest muscle fibres were determined in the lateral rectus muscle of sheep and the superior rectus muscle of humans respectively. The muscle fibres in primary bundles were found to be much intensive in sheep eye muscles compared with those of humans. Consequently, despite to less number of fibres in muscle bundles, connective tissue between the bundles was seen much more abundantly in humans who have more eye movements compared with those of sheep

    A geometric and mechanical description of the talus and cochlea tibiae in horse and ox
    (Bursa Uludağ Üniversitesi, 2021-06-29) İşbilir, Fatma; Çelik, A. Burcu; Arslan, Kadri; Bulca, Betül; Yıldız, Bahri; Fen Edebiyat Fakültesi; Anatomi Ana Bilim Dalı; 0000-0002-6110-1302; 0000-0002-6948-8281; 0000-0002-1440-7050; 0000-0001-5861-0184; 0000-0002-6096-7833
    In this study, geometrical and mechanical identification of the talus and cochlea tibiae in horse and ox is presented. The shape of the expressed bones of these animals can be considered as rotational surfaces of planar curves. The model is established based on the bolt-nut mechanism while interpreting the relationship between talus and tibiae, and describing geometrical differences between ox and horse in functional anatomy. The results obtained from the geometric and mechanical data have led to the conclusion that lateral and friction forces applied on talus and cochlea tibiae of the horse are higher than that in ox. According to these results, the data obtained helps the horses to stand longer.

    Promising effects of vinasse use on bone strength in laying hens
    (Bursa Uludağ Üniversitesi, 2022-12-14) Süzer, Bayram; Eren, Gülsüm; Atamay, Kerem; Veteriner Fakültesi; Hayvan Besleme ve Beslenme Hastalıkları Ana Bilim Dalı; 0000-0002-2687-1221; 0000-0002-4808-2776; 0000-0002-6891-4613
    This study was carried out to determine the effects of vinasse on bone strength and some material properties in laying hens with specific amounts of vinasse added to their diets. The study was the first to determine the mechanical properties of laying hens fed a diet supplemented with vinasse. The study was conducted on tibiotarsi of two hundred 94-week-old laying hens which were selected randomly from a commercial farm. Morphometric measurements were made using a digital scale and caliper, and mechanical data were collected from tibiotarsi using a three-point bending test with a compression-tension machine. The laying hens fed with vinasse had higher tibiotarsal length and weight than those in Control group. The groups fed with vinasse were significantly stiffer and had a higher breaking force than Control group (P=0.002, P<0.001). In conclusion, significant and promising bone material properties were obtained from the laying hens fed with vinasse.
