Soysal D  Cibik R  Aydin C  Ak İ 《Tropical animal health and production》2011,43(4):817-823

Growth performance, carcass characteristics, post-slaughtering and haematological parameters of Kivircik and Karacabey Merino male lambs in conventional and organic management systems were compared. The animals which were weaned at 7 weeks of age were divided into Kivircik conventional, Kivircik organic (KO), Karacabey Merino conventional and Karacabey Merino organic (MO) groups containing 12 lambs each. Fattening was ended when lambs attained 35 kg of live weight. The time to attain the determined fattening weight was significantly different among the groups, and Merino lambs having higher live weight gain were earlier than Kivircik lambs (p?相似文献   

Morphology of the filiform lingual papillae in porcupine (Hystrix cristata)     

Karan M  Yilmaz S  Aydin A 《Anatomia, histologia, embryologia》2011,40(2):100-103

The light and scanning electron microscopic structure of the filiform lingual papillae was studied in five adult porcupine (three males and two females). The tongue was characterised by a round tip, a rostral median sulcus and a deep lingual fossa which was situated just rostral to a prominent inter-molar eminence corresponding to a torus linguae. The filiform papillae were curved, enclosed a large connective tissue core and were separated by wide inter-papillary zones covered by a thick epithelium. Most filiform papillae had a cylindrical shape, but the rostral and central parts of the tongue contained a number of flat, comb-shaped papillae with rounded tips.  相似文献   

Effect of Trachelobdella lubrica (Hirudinea: Piscicolidae) on biochemical and haematological characteristics of black scorpion fish (Scorpaena porcus, Linnaeus 1758)     

Ekrem Sanver Celik  Seyit Aydin 《Fish physiology and biochemistry》2006,32(3):255-260

Black Scorpion fish (Scorpaena porcus Linnaeus 1758) caught during monthly sampling carried out in 2003 in the Dardanelles, Turkey, were examined for the parasite. Trachelobdella lubrica. Infested fish were caught only during December 2003, and the clinical conditions of the 12 fish naturally infested with T. lubrica included fin rot, swollen foci of skin and haemorrhages of the gill and abdominal skin. The prevalence, intensity and abundance of infestation in December 2003 were 40%, 1.75 and 0.70, respectively. The average hepatosomatic index of the infested fish was lower than that of noninfested fish, while the means of the kidney index, splenosomatic index, condition factor, body weight and length were not significantly different between the infested and noninfested fish groups. Blood analysis was conducted on 12 naturally infested and 12 healthy (noninfested) Black Scorpion fish to determine the possible characteristic changes in blood parameters of the fish in response to natural infestation with T. lubrica. Blood leucocyte counts, haematocrit levels, serum total protein, albumin phosphorus, urea, glucose, globulin, cholesterol and triglyceride concentrations in naturally infested Black Scorpion fish were significantly less than those of the noninfested fish (p < 0.05). No significant decreases were observed in the serum sodium, iron, calcium, potassium, chlorine, blood urea nitrogen and creatinine values of the naturally infested fish. Blood haemoglobin values, erythrocyte counts and serum glutamate aspartate aminotransferase (glutamate oxalacetate transaminase), alanine aminotransferase (glutamate pyruvate transaminase), uric acid and very low-density lipids levels of infested fish were insignificantly greater than those in healthy fish.  相似文献   

Nanopatterning by block copolymer micelle nanolithography and bioinspired applications     

Lohmüller T  Aydin D  Schwieder M  Morhard C  Louban I  Pacholski C  Spatz JP 《Biointerphases》2011,6(1):MR1-M12

This comprehensive overview of block copolymer micelle nanolithography (BCMN) will discuss the synthesis of inorganic nanoparticle arrays by means of micellar diblock copolymer approach and the resulting experimental control of individual structural parameters of the nanopattern, e.g., particle density and particle size. Furthermore, the authors will present a combinational approach of BCMN with conventional fabrication methods, namely, photolithography and electron beam lithography, which combines the advantages of high-resolution micronanopatterning with fast sample processing rates. In addition, the authors will demonstrate how these nanoparticle assemblies can be transferred to polymer substrates with a wide range of elasticity. In the second part of this report the authors will introduce some of the most intriguing applications of BCMN in biology and materials science: The authors will demonstrate how nanoparticle arrays may be used as anchor points to pattern functional proteins with single molecule resolution for studying cellular adhesion and present a technological roadmap to high-performance nanomaterials by highlighting recent applications for biomimetic optics and nanowires.  相似文献   

Genetic diversity and relationships within Citrus and related genera based on sequence related amplified polymorphism markers (SRAPs)     

A. Uzun  T. Yesiloglu  Y. Aka-Kacar  O. Tuzcu  O. Gulsen 《Scientia Horticulturae》2009

Sequence related amplified polymorphism (SRAP) markers were used to detect molecular marker polmorphisms among 86 citrus and their relatives in Aurantioidea. Twenty-one SRAP primer combinations produced a total of 376 polymorphic fragments with an average of 17.9 per primer combination and an average polymorphism information content (PIC) of 0.86. The unweighted pair group method arithmetic average (UPGMA) analysis demonstrated that the accessions had a similarity range from 0.28 to 1.00 with a mean of 0.64. The subtribe Clauseninae (tribe Clauseneae) separated from the subtribes of the tribe Citreae. The subtribe Balsamocitrinae (tribe Citreae) was the most distant from the others. In the Citrinae, ‘primitive citrus fruit trees’ and ‘near citrus fruit trees’ groups did not clearly separate from each other but all genera in these groups were distinct. On the other hand, subgenus Papeda and subgenus Citrus were not separated clearly in the dendrogram. C. maxima, C. medica and C. reticulata separated into three distinct clusters in agreement with three ‘true basic species’ thesis. Similarity-based analyses supported the theory of few ancestral species in Aurantioidea.  相似文献   

Characterization for yield, fruit quality, and molecular profiles of lemon genotypes tolerant to ‘mal secco’ disease     

A. Uzun  O. Gulsen  G. Kafa  U. Seday  O. Tuzcu  T. Yesiloglu 《Scientia Horticulturae》2009,122(4):556-561

‘Mal secco’ is a serious disease of lemon and other citrus species, reduces lemon production, and limits the use of susceptible cultivars especially in the Mediterranean countries, against which there is no effective management system to control the disease. The objective of this study was to determine yield efficiency, tree and fruit characters, and molecular profiles of the selected promising genotypes in lemon breeding program to develop ‘mal secco’ tolerant lemon cultivars. After 4 years of evaluation, ‘Tuzcu 894’, a progeny of ‘Finike Yerli Yuvarlak’ and ‘Kutdiken’, was designated as promising genotype with high yield, fruit weight, juice content and low seed number contrary to ‘Kutdiken’ as control. ‘Tuzcu 8911’ was suitable for dense planting having the highest yield in CV. In addition, these two promising genotypes survived after many years being subjected to artificial and natural P. tracheiphila infections and harsh winter temperatures, which were attractive to the citrus industry. Molecular analysis, as assessed with 11 inter-simple sequence repeats (ISSR) primers, indicated that ‘Tuzcu 09 Aklimon’ and its selections, ‘Tuzcu 896’, ‘Tuzcu 897’ and ‘Tuzcu 898’, were distinct from the other genotypes with similarity value of 0.82. Genetic variation among the other lemon genotypes was low and some of the genotypes were identical. It was concluded that variations in the agronomical characters are mainly due to mutations.  相似文献   

Effects of dietary chromium picolinate and ascorbic acid supplementation on egg production, egg quality and some serum metabolites of laying hens reared under a low ambient temperature (6 degrees C).     

K Sahin  M Onderci  N Sahin  S Aydin 《Archives of Animal Nutrition》2002,56(1):41-49

This experiment was conducted to evaluate the effects of chromium (chromium picolinate, Cr Pic) and vitamin C (L-ascorbic acid) supplementation on egg production and egg quality in laying hens (Hy-Line) kept at 18 degrees C (at thermo-neutral zone) or 6 degrees C (cold stress) in temperature-controlled rooms. One hundred and fifty laying hens (32 week-old) were divided into 5 groups, 30 hens per group. The laying hens kept at 6 degrees C temperature were fed either a basal diet (low temperature-basal diet, LTB group) or the basal diet supplemented with either 400 micrograms of Cr per kg diet (Cr group), 250 mg of L-ascorbic acid per kg diet (Vit C group) or 400 micrograms of Cr plus 250 mg of L-ascorbic acid per kg diet (Vit C + Cr group) while hens kept at 18 degrees C fed a basal diet (thermo-neutral-basal diet, TNB group). Performance and egg quality were significantly reduced in LTB group compared with TNB group. Supplemental chromium and vitamin C significantly increased live weight change, egg production, and improved feed efficiency in cold-stressed hens compared with group fed the basal diet at 6 degrees C brought up to the values of the group reared under thermoneutral conditions (18 degrees C). Egg production and egg weight were also greater in each supplemental group compared with the LTB group. Separately or as a combination, supplemental chromium and vitamin C increased serum insulin but decreased corticosterone, glucose and cholesterol concentrations. Results of the present study show that supplementing vitamin C and chromium, particularly as a combination, improved the performance of cold-stressed hens. Such a combination of supplement can offer a potential protective management practice in preventing cold stress-related losses in performance of laying hens.  相似文献

Test of a combined soil moisture/soil heat simulation model on a bare field soil in Southern Turkey     

Mehmet Aydin  Bernd Huwe 《植物养料与土壤学杂志》1993,156(5):441-446

In order to simulate soil suction and soil temperature, a field study was carried out in the experimental farm of the Agricultural Faculty, University of Cukurova (Adana/TURKEY), for a period of two years. During this period the soil was bare. Data collected regularly include soil suction and soil temperature. Meteorological data were obtained from the Adana Climatological Station. Data on soil suction and soil temperature were used to calibrate the simulation model, proposed by Huwe and van der Ploeg (1988). It was found that the model, after having been calibrated, performed quite well. A fair agreement between measured and simulated soil temperatures was obtained. However, the calculated and measured soil suction values were found to be considerably different. The simulation model used in this study appears to be applicable for the conditions of the Cukurova Region in Southern Turkey.  相似文献   

Identification of sweet cherry cultivars (Prunus avium L.) and analysis of their genetic relationships by chloroplast sequence-characterised amplified regions (cpSCAR)   总被引：1，自引：0，他引：1  

Aydin Turkec  Muge Sayar  Berthold Heinze 《Genetic Resources and Crop Evolution》2006,53(8):1635-1641

Ten cpSCAR markers that show polymorphism in Prunus avium were used to fingerprint sweet cherry cultivars. The purpose of the study was also to contribute to identification and to help determine their genetic interrelationships. Samples of ‘0900 Ziraat’, a superior Turkish variety, which were collected in several locations all over Turkey, had identical cpSCAR patterns, and they resembled a common European haplotype, A. ‘Sweetheart’, ‘Summit’ and ‘Canada Giant’ and their haplotype are intermediate between the previously described haplotypes A and B, which were originally found in Central and Eastern European sweet and wild cherries, and those from Northern Turkey, respectively. The data therefore suggests a local maternal descent (within Europe and Asia Minor) of the cultivars analysed. Our results show that chloroplast DNA analysis is a straightforward way to classify cherry cultivars. We compare our results to others previously reported for sweet cherry cultivars, and conclude that cpSCAR diversity data could be considered for phylogenetic studies in this group.  相似文献
