Biotechnical production processes often operate with plasmid-based expression systems in well-established prokaryotic and eukaryotic hosts such as Escherichia coli or Saccharomyces cerevisiae, respectively. Genetically engineered organisms produce important chemicals, biopolymers, biofuels and high-value proteins like insulin. In those bioprocesses plasmids(More)
Syndecan-1 (CD138), a heparan sulfate proteoglycan, acts as a coreceptor for growth factors and chemokines and is a molecular marker associated with epithelial-mesenchymal transition during development and carcinogenesis. Resistance of Syndecan-1-deficient mice to experimentally-induced tumorigenesis has been linked to altered Wnt-responsive precursor cell(More)
Optimal embeddings of spaces of generalized smoothness in the critical case The talk is based on a joint work with Susana D. Moura and J ´ ulio S. Neves. We study necessary and sufficient conditions for embeddings of Besov spaces of generalized smoothness B (n/p,Ψ) p,q (R n) into generalized H ¨ older spaces Λ µ(·) ∞,r (R n). In particular, we are able to(More)
We provide non-smooth atomic decompositions for Besov spaces B s p,q (R n), s > 0, 0 < p, q ≤ ∞, defined via differences. The results are used to compute the trace of Besov spaces on the boundary Γ of bounded Lipschitz domains Ω with smoothness s restricted to 0 < s < 1 and no further restrictions on the parameters p, q. We conclude with some more(More)
OBJECTIVE When questionnaires are used for pain assessment, the order effect must be taken into consideration; that is, whether the answer to a pain item is influenced by answers given to previous items. This study aimed to evaluate possible order effects in children and adolescents when answering pain items. Furthermore, the possible influence of sex on(More)
BACKGROUND Doubling of serum creatinine is often used as a marker for worsening kidney function in nephrology trials. Most people with chronic kidney disease die of other causes before reaching end-stage renal disease. We were interested in the association between doubling of serum creatinine and the risk of a first-time diagnosis of angina pectoris,(More)
