Radiation-related wounds challenge surgeons in all disciplines of surgery. Wound-healing complications are commonplace, and solutions for reconstruction are limited. Muscle and musculocutaneous flaps have improved this situation. But the question is, does previous radiation of the muscle to be transposed affect the outcome? 143 consecutive previously irradiated patients treated with muscle...

The usefulness of echocardiography in evaluating patients who have undergone Mustard's procedure for d-transposition of the great vessels was investigated by examining the M-mode studies and cardiac catheterization data of 20 patients at least 1 year after operation. The patients were separated into two groups using the findings at cardiac catheterization. The 12 patients in group 1 were asympt...

OBJECTIVES/HYPOTHESIS To evaluate the increase in access to the maxillary sinus (MS) with transnasal endoscopic medial maxillary sinus wall transposition (TEMMT), while preserving major structures of the nasal cavity. STUDY DESIGN The study was divided into three parts: anatomical, radiographic, and case series. METHODS Three cadaveric dissections (total of six sides) confirmed the feasibil...

BACKGROUND There are two main surgical approaches, simple ulnar nerve decompression at the elbow, and anterior transposition of the nerve in treatment of cubital tunnel syndrome. Both techniques were reported in literature in details with similar reported success rates. Here, we present a modified simple de-compression surgical technique in treatment of cubital tunnel syndrome. METHODS Fifty...

The histone-like nucleoid structuring protein (H-NS) is an important regulator of stress response and virulence genes in gram-negative bacteria. In addition to binding regulatory regions of genes in a structure-specific manner, H-NS also binds in a structure-specific manner to sites in the Tn10 transpososome, allowing it to act as a positive regulator of Tn10 transposition. This is the only exa...

Surprisingly little is known about the role of host factors in regulating transposition, despite the potentially deleterious rearrangements caused by the movement of transposons. An extensive mutant screen was therefore conducted to identify Escherichia coli host factors that regulate transposition. An E. coli mutant library was screened using a papillation assay that allows detection of IS903 ...

purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...

A transposition system constructed to detect the transposition of Tn5 to a site upstream of the lacZ gene has revealed that transposition of IS50L can activate downstream genes. Expression is apparently mediated by the NPTII promoter. Transposase produced either by IS50R or by the suppressed IS50L catalyzed transposition of IS50L.

Transposition of Tn5 in Escherichia coli strains containing one or multiple copies of the transposable element was investigated. It was found that the overall frequency of transposition within a cell remained constant regardless of the number of copies of Tn5 present in that cell. Experiments measuring the transposition frequency of differentially marked Tn5s confirmed that the frequency of tra...

PURPOSE To evaluate the usefulness of separate vertical wirings for extra-articular fracture of distal pole of patella. MATERIALS AND METHODS We have analyzed the clinical results of 18 cases that underwent separate vertical wirings for extra-articular fracture of distal pole of the patella from March 2005 to March 2010, by using the range of motion and Bostman score. Occurrence of complicati...
