The amount of calcium in bony structures used for age determination in Cyprinion macrostomus (Heckel, 1843)     

Rahmi Aydin  Dursun &#;en  Metin Çalta  & Özgür Canpolat 《Aquaculture Research》2008,39(6):596-602

In this study, the ages of 76 individuals belonging to the Cyprinion macrostomus (Heckel, 1843) population caught from Murat River near Bingöl city were determined from six different bony structures and the level of calcium mineral of each bony structure was measured using an atomic absorption spectrophotometer. The determined element was statistically examined according to the age, length, weight and sex of the fish. The age, length and weight ranges of the fish were found to be 2–6, 12.0–21.2 mm and 16.3–135.3 g respectively. The relationships between the accumulation of calcium in all bony structures and the fish size (both length and weight) were found to be insignificant (P>0.05). However, a strong relationship was found between fish weight and accumulation of the mineral in vertebra and otolith. A strong correlation was also found between fish length and accumulation of calcium in the dorsal fin ray, followed by the otolith, vertebra and cleithrum bones respectively. Whereas the accumulation of calcium according to the age groups was found to be insignificant for scale and operculum (P>0.05), it was found to be significant for all the other bony structures examined (P<0.05). In conclusion, the accumulation of calcium on some bony structures of C. macrostomus was observed to increase with an increase in age, length and weight of fish, although the increases were not statistically significant at least for some bony structures (P>0.05).  相似文献

Buruk K  Sokmen A  Aydin F  Erturk M 《Fitoterapia》2006,77(5):388-391

The Eastern Black Sea Region has an extensive flora because of ample rainfall lasting all year. In this study, antimicrobial effects of 74 crude extracts of 22 endemic plants were investigated. Among the 30 active crude extracts, water-insoluble crude extracts from Betula medwediewii, Heracleum platytaenium, Primula longipes, Anthemis cretica ssp. argaea and Centaurea helenioides were the prominent ones with their MIC values.  相似文献   

Preliminary assessment of dietary mannanoligosaccharides on growth performance and health status of gilthead seabream Sparus auratus     

Gültepe N  Hisar O  Salnur S  Hoşsu B  Tanrikul TT  Aydin S 《Journal of aquatic animal health》2012,24(1):37-42

A feeding trial was performed to assess the potential beneficial effect of two levels of mannanoligosaccarides (MOS) on the growth performance, feed utilization, hematological parameters, and liver histopathology of gilthead seabream Sparus auratus (also known as gilthead bream). Mannanoligosaccarides were added at the rates of 2 and 4 g/kg to a fish-meal-based control diet, and each diet was given (twice daily [midmorning and midafternoon] to apparent satiation) to triplicate groups of gilthead seabream growers (mean weight = approximately 170 g) in sea cages. The trial lasted 12 weeks, and the average ambient water temperature ranged from 19.6 degrees C to 24.7 degrees C during the experimental period. At the end of the experiment, fish attained market size (350-450 g) and their health status was evaluated by blood analysis and liver histology. There were no differences in survival rates among fish fed experimental diets. However, there were significant improvements in both growth and feed utilization among fish fed diets supplemented with MOS. Hemoglobin (Hb) and hematocrit (Ht) levels and erythrocyte, leukocyte, and thrombocyte (Thr) counts were unaffected by any dietary MOS. The levels of Hb (g/dL; mean +/- SD) and Ht (%; mean +/- SD) were 11.0 +/- 2.5 and 45.6 +/- 6.7 for the control group, 11.1 +/- 1.7 and 39.3 +/- 8.0 for the 2-g/kg group, and 11.2 +/- 1.9 and 40.2 +/- 8.4 for the 4-g/kg group. The mean Thr count ranged from 47.6 to 53.8 x 10(3)/mm3. Despite the apparently higher Thr counts for fish fed diets supplemented with MOS, these differences were not significant. Moreover, no histopathological differences were observed in liver tissue cross sections between control and treatment groups. These results suggest that supplementation of diets with MOS had no significant effects on general fish health.  相似文献   

In vitro antibacterial susceptibility of Arcobacter butzleri isolated from different sources     

Abay S  Kayman T  Hizlisoy H  Aydin F 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2012,74(5):613-616

The objective of this study was to determine the antibiotic susceptibility of Arcobacter spp. isolated from various sources. Seventy Arcobacter spp. isolates were tested for their susceptibility to 13 antimicrobial agents. Antimicrobial susceptibility testing was performed by using the agar disc diffusion method on Mueller-Hinton agar supplemented with 5% defibrinated sheep blood. The antibiotics tested included enrofloxacin, erythromycin, streptomycin, gentamycin, rifampin, tetracycline, ampicillin, trimethoprim/sulfamethoxazole, nalidixic acid, danofloxacin, amoxycillin-clavulonic acid, cefuroxime-sodium, neomycine. Although all the arcobacters tested were susceptible to gentamycin, resistance to three or more antibacterial agents (especially, trimethoprim/sulfamethoxazole, cefuroxime-sodium and rifampin) was observed. A. butzleri isolates were found to be resistant to amoxycillin+clavulonic acid, nalidixic acid and ampicillin, at the rate of 20%, 44.28% and 78.57% respectively. In conclusion, gentamycin, streptomycin and tetracycline may be suitable antibiotics for the treatment or control of disease caused by Arcobacter spp. in veterinary and human medicine.  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   

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   

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   

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
