OBJECTIVE The aims of this study were to investigate the frequency and characteristics of dental transpositions and to evaluate associated dental anomalies in a large sample of Turkish Anatolian population. STUDY DESIGN A retrospective study was performed using panoramic radiographs of 6983 patients (4092 females and 2891 males) ranging in age from 12 to 27 subjected to Faculty of Dentistry a...

BACKGROUND We observed several cases of rare vascular anomalies within the femoral triangle during varicose vein operations. METHODS From among 2,093 patients who underwent stripping operations of the great saphenous vein between January 2002 and June 2016, 14 cases of rare vascular anomalies were enrolled in this study. RESULTS Twelve cases of femoral artery and vein transposition (0.57%),...

Both the RecBCD pathway, known for its involvement in homologous recombination and repair of double stranded DNA breaks, and the RecFOR pathway may recognize the linear fragments of DNA that are introduced to the cell during transposition, affecting the transposition frequency. The exact nature of how Rec pathways are involved in transposition is a current topic of research. In this study, usin...

INTRODUCTION Transposition is an anomaly of tooth position, the most frequent of which involves the canine and the first maxillary premolar. We describe the orthodontic treatment of a unilateral transposition of an upper canine and an upper right first premolar in the permanent dentition. CASE PRESENTATION A 12-year-old Caucasian boy presented with transposition of his upper right canine and ...

The pattern of transposition of Ac from the mutable allele bz-m2(Ac) has been investigated. Stable (bz-s) and finely spotted (bz-m(F)) exceptions were selected from coarsely spotted bz-m2(Ac) ears. The presence or absence of a transposed Ac (trAc) in the genome was determined and, when present, the location of the trAc was mapped relative to the flanking markers sh and wx. The salient general f...

In this note, we give a complete proof of the cutoff phenomenon for the star transposition random walk on the symmetric group.

BACKGROUND Frequency transposition has gained renewed interest in recent years. This type of processing takes sounds in the unaidable high-frequency region and moves them to the lower frequency region. One concern is that the transposed sounds mask or distort the original low-frequency sounds and lead to a poorer performance. On the other hand, experience with transposition may allow the listen...

premature ovarian failure (pof) is a heterogeneous syndrome with several causative factors. autoimmune mechanisms are involved in pathogenesis of 4-30 % of pof cases. the present review focuses on the role of autoimmunity in the pathophysiology of pof. the evidences for an autoimmune etiology are: demonstration of ovarian autoantibodies, the presence of lymphocytic oophoritis, and association w...

background: previous studies have reported the antifertility activities of sulfonamides. this study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. methods: a total of 54 rats were randomly divided into 9 groups (n=6) . group i served as the control and group ii (vehicle) received saline. other groups, iii to ix,...
