Genetic Animal Heritage of Anatolia: Short-beaked Pigeon Genotypes

This study aimed to determine the morphological and morphometric characteristics of Bango, Mısıri and Baska pigeons, which have been preferred to breed as ornamental and diver pigeons in Anatolia. The ages of the pigeons were classified into four groups: 12-24 months of age (age group I), 25-36 months of age (age group II), 37-48 months of age (age group III), and 48 months of age and over (age group IV). These three pigeon genotypes were included in the bird group with short beak and small body structure. There were statistically significant differences among the genotypes in terms of body weight, head length-width, beak length-depth, chest depth-width, thoracic perimeter, tail and body length, wing span-length, tarsus diameter (p?0.01). Considering the body plumage color of pigeons, Mısıri and Bango pigeons show more similar appearance, however Baska pigeons has a different appearance from both genotypes. However, it is thought that it would be appropriate to evaluate morphological data together with genetic analysis. We think that these three pigeon genotypes should be taken under immediate protection in order to protect the domestic gene resources of Turkey.

The morphological and morphometric characteristics of Alabadem pigeons

This study aimed to determine the morphological and morphometric characteristics of Alabadem pigeons, which are grown as ornamental pigeons in Edirne province, and to determine mutual traits with other indigenous pigeon breeds in Turkey by comparing with previous studies. Body weight (P < 0.001), head length (P < 0.01), head width (P < 0.05), beak length (P < 0.001), and tarsus diameter (P < 0.05) of age group III were higher than those of other age groups; however, the wingspan of age group II was greater than that of other age groups in Alabadem pigeon. Compared to other indigenous genotypes in Turkey, the Alabadem pigeon is a small-sized genotype. Alabadem pigeons were similar to Edremit butterfly pigeons and Thracian tumbler pigeons in terms of crested and blackeyed pigeons. On the other hand, the irregularly shaped mark (almond) on the head in Alabadem pigeons was similar to the wide-long irregular shaped mark on the neck of Edremit butterfly pigeons. Some basic plumage colors (black, yellow, and red) and intermediate colors (chickpea and scarlet) were identical to Alabadem pigeons and Thrace roller pigeons. Since Alabadem pigeons have many mutual characteristics with Edremit butterfly pigeons and Thracian roller pigeons, genetic studies may be recommended to determine the degree of relationship among these breeds.Tekirdag Namik Kemal University Scientific Research Project Coordination Unit [NKUBAP.10, 17.138]This study was funded by Tekirdag Namik Kemal University Scientific Research Project Coordination Unit (Project No: NKUBAP.10.GA.17.138)

Türkiye?in yerli gen kaynağı, muradiye dönek güvercinlerinin morfolojik özellikleri]

This study was conducted to investigate the morphological characteristics of Muradiye Dönek pigeon. It is a local animal genetic resource and cultural heritage and has an important place among the genotypes of domestic pigeons in Turkey. The animal material of this study consisted of 100 pigeons (50 females and 50 males) from seven pigeon enterprises. In the study, morphological characteristics were evaluated and morphometric measurements were determined. Body plumage colors of pigeons were determined as black (70%), red (16%) and blue (14%) galaca. In some birds, the yellow beaks and nails may bear black spots, which pigeon breeders refer to as ‘zikir’. The term ‘biyik’ (mustache) is used when black feathers appear among the white feathers on the head, and the term ‘kemer’ (belt) is used when black feathers appear in the tail. The differences between the mean values of body weight and wingspan (P<0.001), chest depth (P<0.05) values were statically significant for age groups, which were reported to affect flight characteristics in birds. As a result, when the morphological characteristics obtained in Muradiye Dönek pigeons are compared with other researchers, it is thought that the selection of these birds were carried out by the breeders in terms of the game behavior such as rotation movement during the diving and landing. Although the data obtained in the study support the hypothesis that Muradiye Dönek pigeons should be defined as a different breed, further studies with DNA analysis are required to confirm this situation. © 2021, Chartered Inst. of Building Services Engineers.

Real-time elastography for differentiation of breast lesions

Backroung: To investigate the diagnostic performance of the elastography-based strain index ratio in the differential diagnosis of malignant and benign breast lesions. Material/Methods: Seventy-nine breast masses that were classified as BI-RADS category 3, 4, and 5 on B-mode ultrasonography (US) were further prospectively evaluated by real-time sonoelastography (RTE). To obtain an optimal cut-off value of the strain ratio for differentiating between malignant and benign breast lesions, RTE findings were compared with histopathology of core needle biopsy samples or with ultrasound follow-up data of the analyzed masses. Results: Seventy-nine breast lesions [BI-RADS category 3 (n=15), BI-RADS category 4 (n=34), and BI-RADS category 5 (n=30)] were classified as malignant (n=36) or benign (n=43). The mean strain index value was 6.59±3.44 (range 0.6-14) for malignant lesions and 2.79±2.16 (range 0.6-8.7) for benign lesions, respectively (p<0.05). As regards the detection of malignant lesions, US was characterized by sensitivity and specificity of 100% (CI 95%; 88-100) and 90% (CI 95%; 76-97), respectively. When an optimal value of the strain ratio (4.25) was obtained by ROC curve analysis, the sensitivity and specificity for diagnosing malignant lesions were 86% (CI 95%; 70-95) and 76% (CI 95%; 60-87), respectively. Conclusions: RTE can play an important role in the differentiation between malignant and benign breast masses, but it should be used in conjunction with ultrasonography

Accidental swallowing of partial denture: a case report

We describe a 42-year-old age woman who accidentally swallowed her lower denture, which was composed of eleven teeth. The daily descent of the denture was followed by plain abdominal radiography and physical examination. The image was localized at the left upper quadrant on admission day, but it stopped on its way at the right lower quadrant on day two and three. Since the patient's complaints increased we planned surgical removal of the denture. In this report, we had discussed the diagnosis, follow up and treatment options of swallowed partial denture with current literature review

Aptamer-modified polymer nanoparticles for targeted drug delivery

The purpose of this study was to develop a model system for targeted drug delivery. This system should enable targeted drug release at a certain tissue in the body. In conventional drug delivery systems, drugs are often delivered unspecifically resulting in unwarranted adverse effects. To circumvent this problem, there is an increasing demand for the development of intelligent drug delivery systems allowing a tissue-specific mode of delivery. Within this study, nanoparticles consisting of two biocompatible polymers are used. Because of their small size, nanoparticles are well-suited for effective drug delivery. The small size affects their movement through cell and tissue barriers. Their cellular uptake is easier when compared to larger drug delivery systems. Paclitaxel was encapsulated into the nanoparticles as a model drug, and to achieve specific targeting an aptamer directed against lung cancer cells was coupled to the nanoparticles surface. Nanoparticles were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FTIR), and nanotracking analysis (NTA). Also their surface charge was characterized from ζ-potential measurements. Their preparation was optimized and subsequently specificity of drug-loaded and aptamer-functionalized nanoparticles was investigated using lung cancer cells. © 2016 by De Gruyter

The impact of vitamin E supplementation on semen parameters and pregnancy rates after varicocelectomy: a randomised controlled study

In this study, we aimed to investigate the impact of vitamin E supplementation on semen parameters and pregnancy after varicocelectomy. Forty-five infertile male patients who were diagnosed with varicocele and underwent subinguinal varicocelectomy were included in the study. After performing subinguinal varicocelectomy, the patients were randomised into two groups: 22 receiving vitamin E for 12 months, and 23 as the control group without receiving any supplementation. The pre-operative parameters of semen analyses and pregnancy rates of both groups were compared with those of post-operative parameters. There were no statistically significant differences between the groups in terms of sperm count and motile sperm percentage, in pre-operative, post-operative 3rd month, post-operative 6th month and post-operative 12th month periods. Repeated-measures anova was performed, and sperm count, percentage of change in sperm count, motile sperm count and percentage of change in motile sperm count of the groups were compared. The administration of vitamin E increased all of these parameters; however, they were not found to be statistically significant. In conclusion, vitamin E supplementation might improve the sperm parameters after varicocelectomy; however, further studies including larger number of samples are needed to make a proper decision on vitamin E supplementation after varicocelectomy

Assessment of Subepithelial Angiogenesis in Acquired Cholesteatoma between Pediatric and Adult Patients

Objective:The aim of this study was to compare subepithelial angiogenesis developing within the perimatrix of the cholesteatoma between pediatric and adult patients.Methods:Sixty-one patients who underwent mastoidectomy for the first intent because of chronic otitis media with cholesteatoma between 1993 and 2013 and from whom appropriate tissue specimens were taken were included in the study. The patients were classified in the pediatric patient group if they were under the age of 18 years and the adult patient group if they were 18 years and older. Immunohistochemical staining for CD-31 was performed on new sections taken during surgery and sections prepared from archived tissues in paraffin blocks. Results were compared between the groups.Results:A total of 61 patients, of whom 25 were pediatric and 36 were adult patients, were included in the study. The mean CD-31 immunopositive microvessel rates were 8.8 (3-15) and 6.61 (2-14) for the pediatric and adult patient groups, respectively. The difference between the groups was statistically significant (p=0.037). Correlation analysis showed a statistically significant negative correlation between the CD-31 immunopositive microvessel rates and age (p=0.036).Conclusion:Subepithelial angiogenesis developing within the perimatrix of the cholesteatoma of the pediatric patients was more expressed than that of the adult patients
