BACKGROUND Pelvic irradiation is essential for improving survival in women with pelvic malignancies despite inducing permanent ovarian damage. Ovarian transposition can be performed in premenopausal women in an attempt to preserve ovarian function. As uncertainty occurs over the proportion of women who are likely to benefit from the procedure, we performed a systematic review and meta-analysis ...

Complete transposition of the great vessels is one of the less common congenital anomalies. Survival after birth is dependent upon the presence of some communication between the right and left sides of the heart that will permit crossing of the greater and lesser circulations and enable venous blood to reach the lungs. The case described below is of particular interest because of the absence of...

Congenitally corrected transposition of the great arteries is a rare heart defect that can be associated with systemic ventricular dysfunction and conduction disturbances. The use of cardiac resynchronization therapy in patients with congenital heart disease is not fully established. The authors report a case of cardiac resynchronization therapy in a 31-year-old woman with a history of congenit...

We give the n! permutations of [n] = {1,2, . . . , n} a cyclic order inspired by the children’s game of Hot Potato. Our order is a transposition Gray code, meaning that consecutive permutations differ by a single transposition. Furthermore, each transposition is restricted in two ways: (1) It must transpose value n (the “hot potato”); (2) It must transpose positions that are circularly adjacent...

We prove lower and upper bounds on bisection widths of the transposition graphs. This class of graphs contains several frequently studied intercon-nection networks including star graphs and hypercubes. In particular, we prove that the bisection width of the complete transposition graph is of order (n:n!) which solves the open problem (R) 3.356 of the Leighton's book 10] and determine nearly exa...

We define an operation called transposition on words of fixed length. This operation arises naturally when the letters of a word are considered as entries of a matrix. Words that are invariant with respect to transposition are of special interest. It turns out that transposition invariant words have a simple interpretation by means of elementary group theory. This leads us to investigate some p...

on the left, whereas in the other it was connected to a left-sided morphologic left ventricle. In both cases transposition of the great arteries was present. The cases have been interpreted as representing rotation of embryonic dand 1-bulboventricular loops following septation. In attempting to describe these heart difficulties in terminology were encountered which were partially overcome by co...

The transposition of bacteriophage Mu serves as a model system for understanding DDE transposases and integrases. All available structures of these enzymes at the end of the transposition reaction, including Mu, exhibit significant bends in the transposition target site DNA. Here we use Mu to investigate the ramifications of target DNA bending on the transposition reaction. Enhancing the flexib...
