background & objective: streptococcosis is one of the bacterial infections in fish, especially rainbow trout which infects brain and nervous systems of fish and is caused by s. iniae . estimation of the impact of disease prevalence by s. iniae in fish farming in some countries is reported about 100 million dollars per year. some of the most effective proteins in pathogenicity of these bacteria ...

BACKGROUND Ethnic diversity in schools increases due to globalization. Thus, the children's social-emotional competence development must be considered in the context of a multi-ethnic classroom. METHODS In this study, the social-emotional competence of 65 Asian-American and Latin-American children was observed at the beginning and the end of their kindergarten year.

Background: Genomic instability is one of primary causes for malignant cell transformation. In this study induced genomic instability expressed as micronuclei in breast cancer (BC) patients with different stages of the disease compared with their unaffected first degree relatives (FDR) and normal unrelated controls was investigated. Materials and Methods: The background and net micronucleus fre...

With the aim of the production of human factor VIII antigen and its corresponding antibody an epitope coding fragment of the light-chain of hFVIII, fused to a His6-tag, was isolated and over-expressed in Escherichia coli. The over-expressed hFVIII-epitope containing peptide was confirmed by its reaction with a rabbit serum directed against native hFVIII as well as antiHis6-tag antibody. An expr...

We deal with the asymptotic behavior of the s-perimeter of a set E inside a domain Ω as s ↘ 0. We prove necessary and sufficient conditions for the existence of such limit, by also providing an explicit formulation in terms of the Lebesgue measure of E and Ω. Moreover, we construct examples of sets for which the limit does not exist.
