Ornithological importance of artificial ponds: a case study at Kabaklı Pond,south-eastern Anatolia,Turkey

The birds of Kabakl? Pond and its near surrounding were surveyed between October 2014 and December 2015 periods. During the study period, 105 bird species that belong to 12 orders and 34 families were detected and represented. Among these species determined, 17 of them certainly, 19 probably and 11 possibly breed in the area, while 58 of them are wintering or transitory migrating birds for the area. Among the recorded species, seven are globally threatened, while 20 are threatened for Turkey without least concern species. Obtained information suggests that this small artificial area has a great importance for many bird species related to habitat that have. Habitat preferences of species were analysed, and it was determined that the most preferred habitats are pond (water surface), wooded and agricultural zones, respectively. Also, the maximum bird number obtained during April and December, while maximum bird species richness observed during April. Results suggest that artificial ponds can be important for birds as feeding, resting and breeding area due to rapidly decline in natural wetland areas. Effective protection of the area requires the prevention of illegal hunting, fishing, human disturbance and pasturing. Also, in order to extend the existing reed and meadow areas, convenient plantation of natural plants at around of pond has a critic role for waterfowl.     

基于实时性优化的内燃机燃烧分析系统研究

采用缸压传感器、数据采集卡、光电编码器和Lab VIEW软件,搭建在线缸压采集和实时燃烧分析系统平台,研究HCCI和RCCI燃烧模式的循环波动特性。针对单循环缸压测量过程中的通道效应干扰,基于频谱分析,采用FFT、线性插值法和IFFT等方法相结合的滤波方式,实现共振峰的在线自适应识别与实时滤波,较好地减少了单循环缸压的干扰误差,使单循环的实时燃烧分析成为可能。随后,基于实时滤波后的缸压曲线,计算得到内燃机的最大压力升高率、燃烧放热率、爆发压力等重要燃烧参数。利用程序算法中同步性良好的生产者/消费者运算模式提高数据的共享能力,实现了数据实时运算与数据快速储存的并行处理,提高了燃烧计算的实时性;针对发动机不同工作阶段采用了不同精度层次的计算方法,减少了进排气、压缩和膨胀阶段的计算耗时,在计算量较大的燃烧放热率计算部分,通过适当简化计算公式和公式节点运算模块来提高燃烧系统的实时性。最后,分析了燃烧分析系统的实时性,并进行了燃烧分析系统的实验验证。

Detection and characterization of phytoplasmas in diseased stone fruits and pear by PCR-RFLP analysis in Turkey

During the late summer-early autumn of 2002, surveys were carried out in Turkey to determine the presence of phytoplasma diseases in fruit trees. Phytoplasmas were detected and characterized by PCR-RFLP analysis and TEM technique in stone fruit and pear trees in the eastern Mediterranean region of the country. Six out of 24 samples, including almond, apricot, peach, pear and plum, gave positive results in PCR assays. RFLP analysis usingSspI andBsaAI enzymes of PCR products obtained with primer pair f01/r01 enabled identification of the phytoplasmas involved in the diseases. Stone fruit trees, including a local apricot variety (‘Sakıt’) and a pear sample, were found to be infected with European stone fruit yellows (ESFY, 16SrX-B) and pear decline (PD, 16SrX-C) phytoplasmas, respectively. This is the first report in Turkey of PD phytoplasma infecting pear and of ESFY phytoplasma infecting almond, apricot, myrobalan plum and peach; ESFY phytoplasma infecting Japanese plum was previously reported. http://www.phytoparasitica.org posting July 21, 2005.     

Effect of Jiawei Sini Decoction on glucocorticoid receptor in thymocytes of chronic psychological stress rats

AIM: To observe the effect of Jiawei Sini Decoction (JWSND) on glucocorticoid receptor (GCR) in thymocytes of chronic psychological stress rats. METHODS: The rats were randomly divided into 4 groups, control group (C), model group (M), group treated by JWSND C₁, group treated by ginsenosides C₂. The number of thymocyte GCR sites and the GCR nuclear thanslocation rate were detected by radioimmunoassay. RESULTS: Compared with the control group, in the model group, the thymocyte weight index lowered significantly ( P<0.05 ), and the GCR nuclear thanslocation rate was increased significantly ( P<0.01 ), but the number of thymocyte GCR sites was unchanged. Compared with the model group, thymus gland weight indexes of C₁ and C₂ were increased significantly ( P<0.05 ), while the GCR nuclear thanslocation rate lowered significantly ( P<0.01 ). Moreover, no significant difference was found in all indexes between C₁ and control group. CONCLUSION: The inhibitory effect of glucocorticoid on the thymus could be significantly reversed by JWSND via suppressing the thanslocation of GCR from cytoplasm to nucleus in chronic psychological stress rats.

Identification of irisin immunoreactivity in porcupine (Hystrix cristata) adrenal glands and kidneys

Irisin, a novel peptide, was initially been shown to be expressed explicitly in the muscle tissues. We studied the presence of irisin immunoreactivity in porcupine adrenal glands and kidneys. Immunocytochemistry showed that irisin was localised both in the adrenal cortex and adrenal medulla. In organs, irisin immunoreactivity was found in the tubular and collecting system of the nephron. The functional role of irisin in the adrenal gland and kidney has not been precisely yet. However, irisin might have a paracrine and autocrine function as do other locally produced peptides.     

Recovery of brodifacoum in vomitus following induction of emesis in dogs that had ingested rodenticide bait

AIM: To assess the benefit of inducing emesis in dogs that have ingested rodenticide bait containing brodifacoum (BDF), by determining the amount of BDF in bait recovered from the vomitus relative to the estimated amount consumed.

METHODS: Between 2014 and 2015 samples of vomitus from seven dogs that ingested rodenticide baits containing BDF were submitted by veterinarians in New Zealand. All seven dogs had been given apomorphine by the veterinarian and vomited within 1 hour of ingesting the bait. Some or all of the bait particles were retrieved from each sample and were analysed for concentrations of BDF using HPLC. Based on estimations of the mass of bait consumed, the concentration of BDF stated on the product label, and the estimated mass of bait in the vomitus of each dog, the amount of BDF in the vomited bait was calculated as a percentage of the amount ingested.

RESULTS: For five dogs an estimation of the mass of bait ingested was provided by the submitting veterinarian. For these dogs the estimated percentage of BDF in the bait retrieved from the vomitus was between 10–77%. All dogs were well after discharge but only one dog returned for further testing. This dog had a normal prothrombin time 3 days after ingestion.

CONCLUSIONS AND CLINICAL RELEVANCE: The induction of emesis within 1 hour of ingestion can be a useful tool in reducing the exposure of dogs to a toxic dose of BDF. The BDF was not fully absorbed within 1 hour of ingestion suggesting that the early induction of emesis can remove bait containing BDF before it can be fully absorbed.
