Highly pathogenic avian influenza (HPAI) H5N1 virus is causing the death of a large number of wild birds and poultry. HPAI H5N1 was reported in the north of Iran in 2011. In this study, two A/Chicken/Iran/271/2011 and A/Duck/Iran/178/2011 viruses were genetically characterized by sequence analysis of Hemagglutinin (HA) and Neuraminidase (NA) genes. Phylogenetic analysis revealed that these viruses were different from previous Iranian isolates (Clade 2.2) and belonged to the subclade 2.3.2.1. The results showed that the detected viruses are almost identical to each other and closely related to HPAI H5N1 strains isolated in Mongolia in 2010. Based on the amino acid sequence analysis, these viruses at their HA cleavage sites contained the multibasic amino acid motif PQRERRRK-R/GLF lacking a lysine residue compared with the previous reports of the same motif. There is also a 20-amino acid deletion (resides 49–69) in the NA stalk similar to other viruses isolated after 2000. It seems that introduction of HPAI H5N1 to Iran might have happened by wild birds from Mongolian origin virus.  相似文献   

Effect of Satureja khuzestanica essential oil on male rat fertility     

Haeri S  Minaie B  Amin G  Nikfar S  Khorasani R  Esmaily H  Salehnia A  Abdollahi M 《Fitoterapia》2006,77(7-8):495-499

This study was undertaken to study the effect of Satureja khuzestanica essential oil (SKEO) in male rat fertility. SKEO was administered orally at doses of 75, 150, and 225 mg/kg/day for 45 days through drinking water. Treated and control rats were mated with female on day 45 of treatment. SKEO significantly improved all the parameters evaluated such as potency, fecundity, fertility index, and litter size. Moreover, concentrations of FSH and testosterone were significantly increased in SKEO-treated groups. Also the weights of testes, seminal vesicles, and ventral prostate weights were increased by SKEO (225 mg/kg). Histopathological analysis showed that in male rats treated with SKEO (150, 225 mg/kg) the number of spermatogonium, spermatid cords, Leydig cells, and spermatozoids was increased. Also in these groups, the Sertoli cells were hypertrophic.  相似文献   

Preparation of glucosamine from exoskeleton of shrimp and predicting production yield by response surface methodology     

Mojarrad JS  Nemati M  Valizadeh H  Ansarin M  Bourbour S 《Journal of agricultural and food chemistry》2007,55(6):2246-2250

Chitin was prepared from Persian Gulf shrimp (Metapenaeus monoceros), and then, the obtained chitin was hydrolyzed by hydrochloric acid solutions. The production yield of glucosamine hydrochloride from chitin was optimized, and the effect of three factors (acid concentration, acid to chitin ratio, and reaction time) was investigated. A Box-Behnken design by Minitab software created 12 reactions with different conditions. Each reaction was performed in two replicates. Response surface methodology was used for predicting the glucosamine preparation. The optimum conditions for glucosamine hydrochloride preparation were 30 and 37% hydrochloric acid, 9:1 (v/w) acid solution to solid ratio, and 4 h of reaction time. Time ratio and time acid concentrations were the effective factors on the yield.  相似文献   

Use of a multifenestrated indwelling lavage system for treatment of septic digital teno-synovitis in cattle     

DE ANDERSON  D. ALLEN  G. ST-JEAN  AH PARKS 《Australian veterinary journal》1997,75(11):796-799

Septic tenosynovitis was diagnosed in seven cattle on the basis of history, physical examination, radiographs, cytological examination of tendon sheath fluids, and microbial culture. A commercially available indwelling multifenestrated silicone rubber drain was used to perform frequent lavage of the flexor tendon sheaths. The sepsis resolved in all cattle. Five of six cattle for which long-term (> 1 year) follow-up information was available were clinically sound on the affected limb and had remained productive members of the herd.  相似文献   

Regional autonomy and local resource management in Indonesia     

Bakti Setiawan  Sudharto P. Hadi 《Asia Pacific viewpoint》2007,48(1):72-84

Abstract: As the largest archipelagic nation in the world, with distinctive environmental conditions and biodiversity, Indonesia on the one hand has tremendous natural and environmental riches while on the other hand faces a variety of environmental problems. After three decades of the New Order era, 1967–1998, Indonesian society is in a crucial transformation process towards a more democratic era. At the same time, as indicated in that country's decentralisation laws No. 22/99 and 25/99, Indonesia is also shifting its style of government, from a centralistic to decentralised one. These two trends are happening simultaneously with globalisation prompting a flow of global capital that directly increases pressure on the Indonesian environment. This paper evaluates the decentralisation of environmental management programmes in Indonesia and focuses on the implications of these changes. The weaknesses of current environmental policies and programmes in Indonesia, which give too dominant a role to the government and neglect civil society's involvement in natural resources and environmental management, are analysed. Further, the paper addresses the lack of attention to date to issues of environmental rights and justice that create many complex environmental and social conflicts throughout Indonesia. We conclude by recommending some fundamental changes to environmental policies and programmes in the decentralised system.  相似文献   

Effect of Biuret Content in Urea on the Growth and Nitrogen uptake of some Grain Crops in Egyptian Soils     

A. H. Abdel Hadi  M. S. Khadr  M. N. Bakr 《植物养料与土壤学杂志》1983,146(3):379-384

Seven pot experiments were conducted to study the direct and the accumulative effect of urea containing (0.4, 1.0, 1.5, 2.0, 3.0 and 4.0 %) biuret on the growth of rice, wheat, and maize plants and their N content and N uptake in two fine textured alluvial soils and one sandy clay loam (highly calcareous) soil. It was found that both rice and wheat grain yields were not significantly reduced in all soils where urea containing high percentage of biuret was used namely 3 % and 4 %. Ammonium sulphate fertilizer was superior to urea in plant production only in the sandy clay loam. Moreover, the N recovery was higher in the alluvial soils in comparison to the sandy clay loam. The accumulative addition of biuret to the soils did not further reduce either the growth rate or the N uptake of the plants.  相似文献

Global desertification: building a science for dryland development   总被引：6，自引：0，他引：6  

Reynolds JF  Smith DM  Lambin EF  Turner BL  Mortimore M  Batterbury SP  Downing TE  Dowlatabadi H  Fernández RJ  Herrick JE  Huber-Sannwald E  Jiang H  Leemans R  Lynam T  Maestre FT  Ayarza M  Walker B 《Science (New York, N.Y.)》2007,316(5826):847-851

In this millennium, global drylands face a myriad of problems that present tough research, management, and policy challenges. Recent advances in dryland development, however, together with the integrative approaches of global change and sustainability science, suggest that concerns about land degradation, poverty, safeguarding biodiversity, and protecting the culture of 2.5 billion people can be confronted with renewed optimism. We review recent lessons about the functioning of dryland ecosystems and the livelihood systems of their human residents and introduce a new synthetic framework, the Drylands Development Paradigm (DDP). The DDP, supported by a growing and well-documented set of tools for policy and management action, helps navigate the inherent complexity of desertification and dryland development, identifying and synthesizing those factors important to research, management, and policy communities.  相似文献   

Potential role of viral surface glycoproteins in the replication of H3N2 triple reassortant influenza A viruses in swine and turkeys     

Yassine HM  Khatri M  Lee CW  Saif YM 《Veterinary microbiology》2011,148(2-4):175-182

The H3N2 triple reassortant (TR) influenza viruses emerged in swine in 1998 and then in turkeys in 2003. It was then hypothesized that these viruses crossed the species barrier and transmitted from pigs to turkeys. In previous work we identified viruses with different transmission behavior between the two species, of which A/turkey/Ohio/313053/04 (TK04) transmitted both ways between swine and turkeys, and A/swine/North Carolina/03 (SW03) did not transmit either way between the two species. Utilizing the 12-plasmid reverse genetics (RG) system, we rescued two viruses (TK04 and SW03) with potentially different transmission behavior between pigs and turkeys. Single gene reassortants (SGR) were generated by switching the hemagglutinin (HA) or the neuraminidase (NA) genes between both viruses, and were evaluated for replication in vitro (pig and turkey tracheal/bronchial epithelial cells) and in vivo (pigs and turkeys). RG-created TK04 replicated more efficiently than SW03 in vitro and in vivo. Additionally, TK04 exhibited better binding affinity to plasma membrane preparations (PMP) from pig and turkey tracheal/bronchial epithelial cells compared to SW03. In study with SGR viruses, the HA protein was found to be essential for TK04 virus transmission amongst turkeys, but not sole factor contributing to the efficient replication of virus in turkeys and pigs. Such findings further highlight the polygenic nature of influenza virus pathogenesis.  相似文献
