The diversity of contemporary swine influenza virus (SIV) strains impedes effective immunization of swine herds. Mucosally delivered, attenuated virus vaccines are one approach with potential to provide broad cross-protection. Reverse genetics-derived H3N2 SIV virus with truncated NS1 (NS1Δ126 TX98) is attenuated and immunogenic when delivered intranasally in young pigs. We analyzed T-cell prim...

this essay approaches the challenges of global translation in the 21st century from what might still be considered a somewhat uncommon example: a direct translation of ismail kadaré's 1978 novel prill e thyër (broken april) from the original albanian into brazilian portuguese in 2001. not only does it examine and compare lexical elements in the source and target texts and the usage of translato...
The HA of influenza virus is a receptor-binding and fusion protein that is required to initiate infection. The HA receptor-binding domain determines the species of sialyl receptors recognized by influenza viruses. Here, we demonstrate that changes in the HA receptor-binding domain alter the ability of the H5N1 virus to spread systemically in mice. The A/Vietnam/1203/04 (VN1203) and A/Hong Kong/...
This approach maximizes sensitivity of serology-based monitoring systems by considering spatial clustering of herds classified as false positive by herd testing, allowing outbreaks to be detected in an early phase. The primary objective of this study was to determine whether swine herds infected with influenza viruses cluster in space, and if so, where they cluster. The secondary objective was ...
background: safety culture and attitude form an integral part of organizations' cultures and their improved levels are influential in the prevention of occupational accidents and injuries. the present study was conducted to assess the safety culture and attitude of workers in the mining industry in iran. materials and methods: the present cross-sectional study was conducted on 172 workers ...
با توجه به نقش عمده ی تعداد زیادی از کنه های بالاخانواده ی raphignathoidea در مهار زیستی کنه های خسارت زا و هم چنین شپشک ها، شناخت دقیق آن ها می تواند در اجرای یک برنامه ی کارآمد کنترل تلفیقی نقش موثری داشته باشد. به منظور بررسی فون کنه های این بالاخانواده در شهرستان ساری، طی سال های 1392 و 1393 در مجموع 751 اسلاید میکروسکوپی از کنه های این بالاخانواده تهیه شد. طی بررسی های انجام گرفته، در مجمو...
Influenza vaccination practice, which is based on neutralizing antibodies, requires being able to predict which viral strains will be circulating. If an unexpected strain, as in the 1997 H5N1 Hong Kong outbreak, or even a pandemic emerges, appropriate vaccines may take too long to prepare. Therefore, strategies based on conserved influenza antigens should be explored. We studied DNA vaccination...
