Artemisia annua L. is an aromatic-antibacterial herb that destroys malarial parasites, lowers fevers and checks bleeding, and of which the secondary compound of interest is artemisinin. The objective of the present study was to determine yield, yield components and artemisinin content of A. annua L. grown under four nitrogen applications (0, 40, 80 and 120 kg ha⁻¹) in the Çukurova region of Turkey in 2004 and 2005. Field trials were conducted at Çukurova University, Agricultural Faculty Field Crops Department. In the study, plant height, number of branches, fresh herbage yield, dry herbage yield, fresh leaf yield, dry leaf yield, essential oil content and artemisinin content (by high performance liquid chromatography, HPLC) were examined. By analysis of variance, nitrogen doses had no any statistical effect on the traits investigated except for artemisinin content. Artemisinin content of the dried leaves were significantly affected by nitrogen applications, which varied from 6.32 to 27.50 mg 100 g⁻¹. Contents were from 120 and 80 kg ha⁻¹ nitrogen for the years of 2004 and 2005, respectively.  相似文献   

Genome-wide association studies of preweaning growth and in vivo carcass composition traits in Esme sheep     

Onur Yilmaz  Mehmet Kizilaslan  Yunus Arzik  Sedat Behrem  Nezih Ata  Orhan Karaca  Cengiz Elmaci  Ibrahim Cemal 《Zeitschrift für Tierzüchtung und Züchtungsbiologie》2022,139(1):26-39

Sheep are considered as a major contributor of global food security. Moreover, sheep preweaning growth traits as well as in vivo carcass composition traits such as ultrasonic measurements of Longissimus dorsi muscle depth (UMD) and back-fat thickness (UFD) are crucially important indicators of meat yield and hot carcass composition. Despite their relative importance for productivity and profitability of a sheep production system, detected QTL for these traits are quite scarce. Therefore, we implemented GWAS for these traits using animal mixed model-based association approach provided by GenABEL in Esme sheep. Three genome-wide and 14 individual chromosome-wide associated SNPs were discovered. As a result, ESRP1, LOC105613082, ZNF641, DUSP5, TEAD1, SMOX, PTPRT, RALYL, POM121C, PHIP, LOC101106051, ZIM3, PEG3, TRPC7, FBXL4, LOC105610397, LOC105616489 and DNAAF2 were suggested as candidates. Some of the discovered genes and involved pathways were already annotated to contribute growth and development in various species including human, mice and cattle. All in all, the results of this study are expected to strongly contribute to shed a light on the underlying molecular mechanisms behind growth and carcass composition traits, with potential implications on studies aiming faster genetic improvement, targeted low-resolution SNP panel designs and genome-editing studies.  相似文献

Some Physicochemical Characteristics,Bioactive Content and Antioxidant Characteristics of Non-Sprayed Barberry (Berberis vulgaris L.) Fruits from Turkey     

Hilal Yildiz  Sezai Ercisli  Memnune Sengul  Elif Feyza Topdas  Omer Beyhan  Ozlem Cakir  Haluk Kemal Narmanlioglu  Emine Orhan 《Erwerbs-Obstbau》2014,56(4):123-129

Increasing consumer demands for indigenous, non-sprayed with pesticides and less-known or “forgotten” fruits necessitate knowledge on their breeding, cultivation, biochemical content, harvesting and marketing. Anatolia is rich for wild edible fruit species and barberry is abundant throughout Anatolia. The aim of this study was to determine some important physicochemical characteristics, bioactive content and antioxidant capacity of fruits from nineteen promising barberry (Berberis vulgaris L.) genotypes grown in the Coruh valley, Northeastern Anatolia. The results indicated genotype-specific differences for most of the physicochemical characteristics, antioxidant capacity and the content of some bioactive compounds. Fruit mass ranged from 0.073 (‘Coruh-7’) to 0.267 g (‘Coruh-11’). Total phenolic content ranged from 2532 (‘Coruh-’) to 3719 mg GAE per liter fruit juice (‘Coruh-11’). The genotype ‘Coruh-12’ had the highest total monomeric anthocyanin content (1004 mg per liter fruit juice) as cyanidin-3-glucoside. The highest total antioxidant capacity was observed in fruits of ‘Coruh-8’ and ‘Coruh-9’ genotypes with all three antioxidant-determining methods. We conclude that the barberry fruits represent a good source of bioactive phytochemicals because of their high phenolic and anthocyanin contents.  相似文献   

Assessment of Biogas use as an Energy Source from Anaerobic Digestion of Brewery Wastewater   总被引：1，自引：0，他引：1

Energy recovery from a crossflow ultrafiltration (UF) membraneunit employed in order to improve the performance of an anaerobic contact digester for the treatment of brewery wastewater was assessed. The performance of the pilot-scale anaerobic UF membrane system was studied for over 15 months. At steady-state conditions, an organic loading rate of 28.5 kg COD m^-3 d^-1, a hydraulic retention time of 4.2 days and overall COD and BOD removal efficiencies of 99% and almost 100% were achieved, respectively. Percent methane in biogas was found to be in a range of 67–79% with the corresponding methane yield of 0.28–0.35 m³ CH₄ kg^-1 COD_removed. The potential energy recovery from the system treating brewery wastewater at an OLR of 28.5 kg COD m^-3 d^-1 was 87 MJ d^-1 which would enable to maintain all energy requirements of the feed pump, mixing and heating of the reactor contents. In addition to this, 71% of the energy requirement for recirculating the reactor content through the membranes would also be recovered.  相似文献   

The ligaments and sesamoid bones of knee joint in New Zealand rabbits     

Orhan IO  Haziroglu RM  Gultiken ME 《Anatomia, histologia, embryologia》2005,34(2):65-71

This study has been conducted on the knee joints of the New Zealand rabbits. A total of 20 knee joints from 10 (five female, five male) adult New Zealand rabbits were studied in the study. Fourteen ligaments and four sesamoid bones including the patellar bone, the infrapatellar adipose body, and the suprapatellar cartilage specifically present in rabbits were grossly observed. The caudal meniscotibial ligaments of the lateral meniscus were noted to be lacking in these rabbits. Moreover, the medial collateral ligament did not have a capsular character in nature. Thus, adipose tissue was determined at a point where the suprapatellar cartilage and patella fused.  相似文献

Orhan IO  Kabak M 《Anatomia, histologia, embryologia》2006,35(4):211-216

The department of National Parks and Protection of Wild Nature sent five (two males, three females) adult long-legged buzzards for investigation of their deaths to Ankara University Veterinary Faculty. Facial bones of buzzards were evaluated. Distinguishing facial features such as strong os premaxillare, cavum nasale filled with spider webbing-like structures, prominent os prefrontalis and processes, H-shaped paraglossum were determined. In this study, we investigated the anatomic properties of facial bones in long-legged buzzard. We also aimed to identify the data using these bones in order to separate different bird species.  相似文献   

Oral vaccination of foxes against rabies in Turkey between 2008 and 2010     

Un H  Eskiizmirliler S  Unal N  Freuling CM  Johnson N  Fooks AR  Müller T  Vos A  Aylan O 《Berliner und Münchener tier?rztliche Wochenschrift》2012,125(5-6):203-208

Following a sustained spill-over event from dogs to foxes, fox rabies spread rapidly in the Aegean region, Turkey. In order to control the outbreak a program of oral vaccination of foxes against rabies was introduced. In the selected vaccination area three annual campaigns between 2008 and 2010 were undertaken during the winter months whereby the vaccine baits were distributed exclusively by plane using a density of 18 baits per km2. Subsequently, fox rabies cases were reported only from locations bordering the non-vaccinated areas. Hence, it was shown that fox rabies control by means of oral rabies vaccination is feasible in Turkey. However, for the progress towards the elimination of fox-mediated rabies in Turkey to be maintained, it is necessary that political and financial support is secured to extend oral vaccination where infected foxes remain.  相似文献   

Development of a loop-mediated isothermal amplification assay for rapid, sensitive and specific detection of a Campylobacter jejuni clone     

Luo Y  Sahin O  Dai L  Sippy R  Wu Z  Zhang Q 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2012,74(5):591-596

Loop-mediated isothermal amplification (LAMP) assay is a simple, rapid and specific detection method and has been used for detection and identification of different Campylobacter species. In this study, we develop a LAMP assay specific for detection of a particular clone (clone SA) of Campylobacter jejuni, associated with the vast majority of recent sheep abortions in the U.S. Using a set of specific primers for C. jejuni IA3902 (a clone SA isolate) and genomic DNA or boiled cell extract as template, the target DNA was amplified at 63 °C for 50 min in a water bath. A positive reaction was identified visually as white precipitate or fluorescence under UV, and confirmed by gel electrophoresis. Detection limit of the assay was comparable to that of conventional PCR. The LAMP was shown to be specific for detection of clone SA when tested on a number of C. jejuni strains of different genetic backgrounds. Applicability of the LAMP assay for specific detection of clone SA was demonstrated in animal tissues experimentally infected with IA3902 or genetically diverse C. jejuni strains. Since clone SA is the predominant cause of sheep abortions in the U.S. and is a zoonotic pathogen, the LAMP assay may be a valuable detection tool in future epidemiological studies.  相似文献
