pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. serious complications should be avoided by retrieval of the stent via different endoscopic techniques. we report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a n...

We show that proxies for firms’ incentives to manage earnings expectations toward beatable levels contain strong predictive power for earnings announcement returns. Firms with stronger incentives to manage expectations predictably underperform before, and subsequently outperform during, their expected earnings announcement months. This predictable V-shaped pattern in prices yields strategy retu...

Sixteen monoclonal antibodies (Mcabs) were prepared against infectious bronchitis virus strain M41, all of them reacting with the peplomer protein. One of them, Mcab 13, was able to neutralize the virus and to inhibit hemagglutination. Competition binding assays allowed the definition of five epitopes, designated as A, B, C, D, and E, of which epitopes A and B are overlapping. Furthermore, the ...

We report a case of an axillary abscess with Streptococcus pyogenes complicated by venous thrombosis. Bacterial etiology and typing were obtained by PCR and sequencing of the 16S rRNA and M-protein genes from abscess material. The bacterium was of serotype M41, and serology indicated that it had expressed procoagulant factors.

The binding of viruses to host cells is the first step in determining tropism and pathogenicity. While avian infectious bronchitis coronavirus (IBV) infection and avian influenza A virus (IAV) infection both depend on α2,3-linked sialic acids, the host tropism of IBV is restricted compared to that of IAV. Here we investigated whether the interaction between the viral attachment proteins and the...

A Saccharomyces cerevisiae-expressed nucleocapsid (N) polypeptide of the M41 strain of infectious bronchitis virus (IBV) was used as antigen in a recombinant yeast-expressed N protein-based enzyme-linked immunosorbent assay (Y-N-ELISA). The Y-N-ELISA was rapid, sensitive, and specific for detecting chicken serum antibodies to IBV, and it compared favorably with a commercial ELISA.

an indirect enzyme–linked immunosorbent assay (elisa) was developed for screening of antibody to avian infectious bronchitis virus (ibv). antigen was prepared from whole-purified ibv massachusetts serotype (br 801 strain). optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed elisa was determined 0.1μg/ml, 1:3000 and 1:100, respe...

Background and Aims: Infectious bronchitis virus (IBV) causes an acute, highly contagious respiratory and kidney disease of chickens which results in significant economic losses in commercial broilers, layers and breeders. Rapid identification of IBV serotypes involved in respiratory complex is a problem in the differential diagnosis. Materials and Methods: In this study, a single and mul...
