Tension-free muscle closure is essential in kidney transplantation, both in adult and pediatric patients. Tight muscle closure may lead to renal transplant compartment syndrome either due to compression of the renal parenchyma or due to kinking of the renal vessels. It may also cause kinking of the transplant kidney ureter, wound dehiscence and incisional hernia. Many techniques have been propo...

finite normalized tight frames are interesting because they provide decompositionsin applications and some physical interpretations. in this article,we give a recursive method for constructing them.

Introduction: The most common type of velopharyngeal valve (VPV) closure is a matter of controversy.The aim of this study was to estimate the most common type of VPV closure, including identification of the type and grade of VPV closure among Egyptian children.  Materials and Methods: This study included patients who were candidates for adenotonsillectomy. In these cases, video-nasoendoscopy an...

A straightforward chiral pool synthesis for a non-natural calystegin, 3-epi-B2, is described. Key steps of this synthesis include an ultrasound-assisted Zn-mediated tandem ring opening reaction followed by a Grubbs’ catalyst-mediated ring closure metathesis reaction. Compared to calystegin B2, the target compound is no longer an inhibitor for a β -glycosidase hence proving that an equatorial hy...

Nasal air flow was measured during the speech of 112 normal subjects (59 females and 53 males) ranging in age from three years to 37 years, six months. Flow was zero during nearly all oral consonant and vowel utterances, suggesting that velopharyngeal closure was air-tight. Flow occurred during all nasal consonants and during vowels adjacent to nasal consonants. These effects were interpreted a...

Rings of differential operators are notoriously difficult to compute. This paper computes the ring of differential operators on a Stanley-Reisner ring R. The D-module structure of R is determined. This yields a new proof that Nakai’s conjecture holds for Stanley-Reisner rings. An application to tight closure is described. @ 1999 Elsevier Science B.V. All rights reserved.
