It is well known that there exist some types of the most frequent errors made by human operators during transmission of data which it is possible to detect using a code with one check symbol. We prove that there does not exist an n-T-code that can detect all single, adjacent transposition, jump transposition, twin, jump twin and phonetic errors over an alphabet that contains 0 and 1. Systems th...
Excision and formation of a covalently closed circular transposon molecule are required for conjugative transposition of Tn916 but are not the only factors that limit the frequency of conjugative transposition from one host to another. We found that in gram-positive bacteria, an increase in the frequency of excision and circularization of Tn916 caused by expression of integrase (Int) and excisi...
Because most surgeons perform an esophagectomy and colonic transposition as the main reconstruction method for patients with esophageal stenosis caused by swallowing corrosive materials, we report 2 cases in which ileocolonic transposition was used to treat such patients. Both patients displayed stenosis in the middle third of the esophagus. Their chief complaint was dysphagia. Ileocolonic tran...
Several trap plasmids (enabling positive selection of transposition events) were used to identify a pool of functional transposable elements (TEs) residing in bacteria of the genus Paracoccus (Alphaproteobacteria). Complex analysis of 25 strains representing 20 species of this genus led to the capture and characterization of (i) 37 insertion sequences (ISs) representing 9 IS families (IS3, IS5,...
BACKGROUND Mariner elements represent the most successful family of autonomous DNA transposons, being present in various plant and animal genomes, including humans. The introduction and co-evolution of mariners within host genomes imply a strict regulation of the transposon activity. Biochemical data accumulated during the past decade have led to a convergent picture of the transposition cycle ...
Ty1 retrotransposons in Saccharomyces cerevisiae are maintained in a state of transpositional dormancy. We isolated a mutation, rtt100-1, that increases the transposition of genomic Ty1 elements 18- to 56-fold but has little effect on the transposition of related Ty2 elements. rtt100-1 was shown to be a null allele of the FUS3 gene, which encodes a haploid-specific mitogen-activated protein kin...
Let A and B be strings with lengths m and n, respectively, over a finite integer alphabet. Two classic string mathing problems are computing the edit distance between A and B, and searching for approximate occurrences of A inside B. We consider the classic Levenshtein distance, but the discussion is applicable also to indel distance. A relatively new variant [8] of string matching, motivated in...
OBJECTIVE To help clarify the optimal surgical strategy for idiopathic, symptomatic ulnar nerve compression at the elbow in terms of overall outcome and morbidity by using objective criteria. METHODS Forty-four surgical candidates were recruited prospectively and were randomized into the neurolysis (n = 23) or transposition (n = 21) arm of the study. Preoperative and postoperative outcomes we...
