Schistosoma mansoni-infected individuals who have low intensities of reinfection following treatment produce immunoglobulin E (IgE) antibodies against a range of S. mansoni adult-worm antigens. One of the targets of the IgE response is an adult-worm sodium dodecyl sulfate-polyacrylamide gel electrophoresis band of 22 kDa (Sm22), which contains an antigen(s)(More)
We have isolated the four separate segments of chicken DNA which contain sequence homology to beta tubulin. With the exception of a fifth region of DNA which appears to contain only a 5' fragment of a beta gene, these four cloned sequences represent all of the beta tubulin encoding DNA in the chicken. Each gene is very similar in structure, containing three(More)
Virtually all higher eucaryotic cells rapidly depress synthesis of new alpha- and beta-tubulin polypeptides in response to microtubule inhibitors that increase the pool of depolymerized subunits. This apparently autoregulatory control of tubulin synthesis is achieved through modulation of tubulin messenger RNA levels. In particular, in cells treated with(More)
We have previously demonstrated that the chicken genome contains at least four different, functional beta-tubulin genes. By using gene specific probes we have now analyzed the relative levels of expression of the four encoded messenger RNA (mRNA) transcripts as a function of chicken development and differentiation. We have found that the RNA transcript from(More)

This article argues that empirical developments in international security governance offer untapped opportunities for strengthening intellectual links between European Union studies and international relations. To uncover these links, the article first demonstrates how the Europe-an Union has started to address various chemical, biological, radiological and(More)
