BACKGROUND Laparoscopic bariatric surgery requires retraction of the left lobe of the liver to provide adequate operative view and working space. Conventional approaches utilize a mechanical retractor and require additional incision(s), and at times an assistant. OBJECTIVES This study evaluated the safety and efficacy of a suture-based method of liver retraction in a large series of patients ...

Volume 30, no. 11, p. 2681–2692, 2010, https://doi.org/10.1128/MCB.01480-09. We hereby retract this article. After publication, the article was found to have image duplications in Fig. 5A and 6B, which represent a major deviation from established scientific standards for publication. We did not notice the duplication during submission. The first author indicated that it happened during transfer...

Schinzel-Giedion syndrome is a rare autosomal recessive disorder characterized by coarse facies, midface retraction, hypertrichosis, multiple skeletal anomalies, and cardiac and renal malformations. Craniofacial abnormalities of this syndrome sometimes resemble a storage or metabolic disease. The pathogenesis of the disease remains unknown. The objective of this report was to emphasize the impo...

in this work, different types of chaotic 1-manifolds which lie on the chaotic spheres or on a torus are introduced. some types of retractions of the chaotic spheres affect on the 1-chaotic systems, and other types of retractions occur to the geometric manifold but make the 1-chaotic manifold invariant. the existed retractions are discussed through new proved theorems. also we construct diffe...

CONTEXT Swimming requires well-balanced scapular-muscle performance. An additional strength-training program for the shoulders is pursued by swimmers, but whether these muscle-training programs need to be generic or specific for endurance or strength is unknown. OBJECTIVE To evaluate isokinetic scapular-muscle performance in a population of adolescent swimmers and to compare the results of tr...

The current project examines the status of (str) retraction, an ongoing, phonetically-motivated sound change, in the Raleigh, NC corpus of sociolinguistic interviews (Dodsworth & Kohn, 2012). Investigating the status of this sound change in apparent time, acoustic analyses of 140 Raleigh-natives was carried out. All tokens of /s/ and /S/ were automatically extracted and the spectral characteris...
