It describes methodological approaches and main cultivation methods and discusses different problems arising during the application of these methods. One of the major problems is the negative effect of large-scale monoculture of seaweeds on natural benthic biocenoses. We express our views

on how to tackle the most acute problems of macroalgal farming on the basis of our own data and data from other authors. The sustainable use of natural monodominant seaweed communities is shown to check details be preferable to mariculture. A detailed analysis is given of various mariculture models and the latest achievements in the integrated farming of seaweeds, fish, crustaceans, and mollusks.”
“Protein phosphorylation is a key mechanism to regulate protein functions. However, the contribution of this protein modification to species divergence is still largely unknown. Here, we studied the evolution of mammalian phosphoregulation

by comparing the human and mouse phosphoproteomes. We found that 84% of the positions that are phosphorylated in one species or the other are conserved at the residue level. Twenty percent of these conserved sites are phosphorylated in both species. This proportion is 2.5 times more than expected by chance alone, suggesting that purifying selection is preserving phosphoregulation. However, we show that the majority of the sites that are conserved at the residue level are differentially phosphorylated between ZD1839 species. These sites likely result from false-negative identifications due to incomplete experimental coverage, false-positive identifications and non-functional sites. In addition, our results suggest that at least 5% of them are likely to be true differentially phosphorylated sites and may thus contribute to the divergence in phosphorylation networks between mouse and humans and this, despite residue conservation between orthologous

proteins. We also showed that evolutionary turnover of phosphosites at adjacent positions ( in a distance range of find more up to 40 amino acids) in human or mouse leads to an over estimation of the divergence in phosphoregulation between these two species. These sites tend to be phosphorylated by the same kinases, supporting the hypothesis that they are functionally redundant. Our results support the hypothesis that the evolutionary turnover of phosphorylation sites contributes to the divergence in phosphorylation profiles while preserving phosphoregulation. Overall, our study provides advanced analyses of mammalian phosphoproteomes and a framework for the study of their contribution to phenotypic evolution.”
“BackgroundThe WBC (the ratio between DIFF and BASO counts of the Sysmex XT-2000iV), hereafter defined as TNC (total nucleated cells), is high in effusions due to feline infectious peritonitis (FIP), as cells are entrapped in fibrin clots formed in the BASO reagent.
