Extensive calcification of mitral apparatus may preclude optimal valve repair, thus requiring debridement. We performed mitral valve replacement in a 55-year-old woman with a modified bileaflet preservation technique to avoid complications related to extensive debridement. Posterior transposition of the anterior leaflet as a buttress over the posterior ventricular wall provided extra support fo...

Purpose: We report the procedure of inferior oblique anterior transposition (IOAT) in the treatment of upshoot in patients with Duane retraction syndrome (DRS). Methods: Two patients with DRS underwent surgery for severe up-shoot. For both patients, the inferior oblique (IO) was transposed to the temporal border of IO insertion. Approximately 64 months of periodic follow-ups for Case 1 and 7 mo...

Recall that variation distance is defined as ‖μ− ξ‖ = 12 ∑ x∈Ω |μ(x)− ξ(x)| = maxA⊂Ω |μ(A)− ξ(A)|. Recall also that for any t > τmix · dln −1e we have ∆(t) ≤ . In general, our goal was to randomly sample elements of a large set Ω from a distribution defined implicitly by assigning a positive weight w(x) to each x ∈ Ω and then normalizing. So, Pr[x is choosen] = w(x) Z where Z = ∑ x∈Ω w(x). Howe...

The bacterial transposon Tn7 is capable of high-frequency transposition to a specific site in the Escherichia coli chromosome, attTn7, and of low-frequency transposition to sites other than attTn7. Using an in vitro insertional mutagenesis procedure, we have identified and characterized five tns (Tn seven) genes that are essential for Tn7 transposition. Three of these genes, tnsA, tnsB, and tns...

The frequencies of one-ended transposition and normal transposition of derivatives of Tn21 that contain mutant inverted-repeat sequences (IRs) have been measured. In general, there was a linear relationship between the log of the frequency of one-ended transposition of a mutant IR and the log of the frequency of normal transposition of an element flanked by a wild-type IR at one end and by the ...

Transposition is a multistep process in which a transposable element DNA sequence moves from its original genetic location to a new site. Early steps in this process include the formation of a transposition complex in which the end sequences of the transposable element are brought together in a structurally precise fashion through the action of the element-encoded transposase protein and the cl...

Tooth transposition is a severe disturbance of tooth order and eruptive position, involving certain teeth that may occur at any of the several sites in the mouth. Maxillary canine-first premolar (MxCP1) transposition is the most frequent tooth transposition. This case report presents the treatment of female patient with bilateral maxillary canine-premolar transposition. The order of transpositi...

BackgroundCompression of the ulnar nerve at elbow is second most frequent site compression in upper limb. Upon release, anteposition may be necessary to avoid dislocation latter when unstable. Numerous techniques are described literature (subcutaneous transposition, intramuscular subfascial medial epicondylectomy …), none which without complications. Based on Han's work, authors propose a techn...
