Inverted and mirror repeats in model nucleotide sequences.

2007

We analytically and numerically study the probabilistic properties of inverted and mirror repeats in model sequences of nucleic acids. We consider both perfect and non-perfect repeats, i.e. repeats with mismatches and gaps. The considered sequence models are independent identically distributed (i.i.d.) sequences, Markov processes and long range sequences. We show that the number of repeats in correlated sequences is significantly larger than in i.i.d. sequences and that this discrepancy increases exponentially with the repeat length for long range sequences.

A chronosequence study of vegetation dynamics on vine and caper terraces of Pantelleria Island (Sicily)

2006

The vegetation of fallow fields of different age in the terraced agricultural landscape of Pantelleria Island (Sicily) was analysed via vegetation relevés. Five age classes in N-facing as well as in S-facing slopes of both vine and caper fallows were differentiated. The main questions were to determine the sequence of plant communities in time and to test some environmental factors for their influence on the course and the speed of succession. The results show that undisturbed abandoned terraces are subject to rapid renaturation: 50 to 80 years old fallows are now covered by dense maquis communities. Both N- and S-facing slopes seem to converge to a Quercus ilex woodland as the climax commu…

Expression and glycosylation studies of human FGF receptor 4

2001

Fibroblast growth factor receptor subtype 4 (FGFR4) has been shown to have special activation properties and just one splicing form, unlike the other FGFRs. FGFR4 overexpression is correlated with breast cancer and therefore FGFR4 is a target for drug design. Our aim is to overexpress high amounts of homogeneous FGFR4 extracellular domain (FGFR4ed) for structural studies. We show that baculovirus-insect cell-expressed FGFR4ed is glycosylated on three (N88, N234, and N266) of the six possible N-glycosylation sites but is not O-glycosylated. The deglycosylated triple mutant was expressed and had binding properties similar to those of glycosylated FGFR4ed, but was still heterogeneous. Large am…
