Stapled hemorrhoidopexy: functional results, recurrence rate, and prognostic factors in a single center analysis.

Purpose: Since its introduction, stapled hemorrhoidopexy (SHP), the so-called Longo procedure, became a widely accepted treatment option for prolapsing hemorrhoids. Nevertheless, from the early years, concerns grew about the early functional results and potential recurrences. In order to evaluate of SHP with special respect to early defecation disorders und recurrences, our single institute high-volume results were evaluated.

Role of paired basic residues of protein C-termini in phospholipid binding.

It is a well known phenomenon that the occurrence of several distinct amino acids at the C-terminus of proteins is non-random. We have analysed all Saccharomyces cerevisiae proteins predicted by computer databases and found lysine to be the most frequent residue both at the last (-1) and at the penultimate amino acid (-2) positions. To test the hypothesis that C-terminal basic residues efficiently bind to phospholipids we randomly expressed GST-fusion proteins from a yeast genomic library.
