Immunohistochemical study on roe deer haemal nodes

Background: The aim of this study was to investigate the immunohistochemical characteristics of the haemal nodes located in the abdominal and thoracic cavities in roe deer (Capreolus capreolus). Materials and methods: In this study, 2 adult male and 2 adult female roe deers in addition to 2 roe deer foetuses at the late foetal stages were used. The avidin-biotin-peroxidase technique was applied to anti-CD3, anti-CD79acy, anti­-macrophage, anti-S100 primary antibodies. Results: Positive results were gained for all the antibodies used. Many CD3 positive T-lymphocytes were seen in the lymphoid tissue areas of the foetal haemal nodes, in the germinal centre of the lymph follicles of the adult haemal nodes and in their lymphatic cords. CD79acy positive cells were less in number while S-100 protein was positive in both lymph follicles and in sinuses of the adult haemal nodes. In foetal haemal nodes, cells positive for S-100 protein were more prevalent in the sinuses. For the MAC387 primary antibody, there were positive macrophages seen in the capsule and trabeculae of the haemal nodes, located denser in males. Macrophage cells in the lymphoid structures and granulocytes in the sinuses of the haemal nodes of both adults and foetuses were positive for MAC387. Conclusions: This study is the first one to define the detailed structural features immunohistochemically in the haemal nodes of the roe deer. Even it’s concluded that the results were similar with the other ruminants, it’s also pointed out that there are certain differences among the foetal, adult male and female haemal nodes of the roe deer.

Anatomical and histological analysis of the salpinx and ovary in Anatolian wild goat (Capra aegagrus aegagrus)

Background: This study determined the anatomical and histological structure of the salpinx and ovary of the Anatolian wild goat (C. aegagrus aegagrus). Materials and methods: The salpinges and ovaries from four wild goats of similar ages were used. These goats were brought to the Kafkas University Wildlife Rescue and Rehabilitation Centre (Kars, Turkey) for various reasons such as traffic accidents or firearm injury, but either could not be saved or were euthanased. Results: The mean length of the ovary was 13.22 ± 1.27 mm, width was 8.46 ± 0.88 mm, thickness was 5.67 ± 0.79 mm, and weight was 0.59 ± 0.17 g. The mean length of the salpinx was 58.11 ± 14.02 mm, width was 0.80 ± 0.22 mm, thickness was 0.41 ± 0.01 mm, and weight was 0.30 ± 0.08 g. The salpinx consisted of three different regions (infundibulum, ampulla, and isthmus). These regions consisted of tunica mucosa, tunica muscularis, and tunica serosa. Prismatic epithelial cells were observed in the lamina epithelialis of the tunica mucosa in every region. Conclusions: The data resulting from this study regarding anatomical and histological structures of the salpinx and ovary in the genital system organs of Anatolian wild goat will support other studies seeking to improve reproductive efficiency and eliminate the danger of extinction of this species

The morphological investigations on the heart and some vessels of bovine foetus between the 15th and 25th weeks of gestation

Background: The aim of this study was to define the morphological and morphometric development of the foetus heart obtained from the domestic cattle in the gestation period of 15–25 weeks. Materials and methods: For this purpose, a total of 30 hearts belonging to cattle foetuses (15 males, 15 females) were used. The ages of foetuses were calculated according to the forehead-to-tail length and examined in three different groups. After dissection; biometric, macroanatomic, morphometric and histological findings were obtained from the foetal hearts according to the groups. In addition, mean values of the morphometric findings were determined. Results: As a result of the study, it was found that with the advancing age the convexity of margo ventricularis dexter increased and margo ventricularis sinister transformed from a convex-concave shape to a flat shape. The heart-to-body weight ratio was determined as 0.08% for Group II female foetuses and 0.09% for all other groups. The heart heights for Groups I, II, and III females were identified as 26.21, 41.00, and 46.27 mm, respectively, and for the males 26.45, 34.89, and 47.15 mm, respectively. In the statistical analysis, it was determined that all the morphometric values measured from the heart correlated significantly with the forehead-to-tail length. Conclusions: The data obtained as a result of the study is thought to help understand the morphological and morphometrical development of the heart, pioneer the attempts to create a foetal cattle heart model, and thus help in the diagnosis of the foetal heart pathologies.acieleck

The Internationalization of Higher Education in Turkey: Creating an Index

The aim of this study is to test the validity and reliability of the Internationalization Index of Higher Education in Turkey, which provides a ranking of institutions of higher education in Turkey according to their degree of internationalization. The item discrimination, construct validity (exploratory and confirmatory factor analyses), and internal consistencies of the index’s indicators and subindicators were tested using data obtained from 300 faculty members. The findings obtained showed that the index was made up of five indicators—(i) university research performance, (ii) curricular efficiency, (iii) international linkages, (iv) student support, and (v) urban sufficiency—as well as of 33 subindicators, and that the index was valid and reliable. The study then made use of the Delphi method to establish the weight of the index’s indicators and subindicators. In sum, it can be said that the study effectively constitutes a proof toward utilization of the Internationalization Index of Higher Education in Turkey for the ranking of institutions of higher education in terms of internationalization
