INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

Determination of skeletal muscle architecture is important for accurately modeling muscle behavior. Current methods for 3D muscle architecture determination can be costly and time-consuming, making them prohibitive for clinical or modeling applications. Computational approaches such as Laplacian flow simulations can estimate muscle fascicle orientation based on muscle shape and aponeurosis location. The accuracy of this approach is unknown, however, since it has not been validated against other standards for muscle architecture determination...

A trigger digit is relatively uncommon in adolescents and often has a different etiology in that age group vs adults. In the pediatric population, trigger digits frequently arise from a variety of underlying anatomic situations, including thickening of the flexor digitorum superficialis or flexor digitorum profundus tendons, an abnormal relationship between the flexor digitorum superficialis and flexor digitorum profundus tendons, a proximal flexor digitorum superficialis decussation, or constriction of the pulleys...

Although overexpression of genes encoding detoxification enzymes is a well-known mechanism of pesticide resistance of mites, the regulators involved in this process are still illiterate. Previous studies in our laboratory demonstrated that the overexpression of six P450 genes contributes to fenpropathrin resistance in T. cinnabarinus. In this study, six transcription factor genes that likely regulate the expression of P450 genes were identified and characterized. Quantitative PCR (qPCR) analysis showed that three transcription factor genes were highly expressed in a fenpropathrin-resistant (FeR) strain of T...

PURPOSE: The transition muscle between the palatopharyngeus (PP) and the superior constrictor of the pharynx (SCP) encircles the pharyngeal isthmus from behind and is designated as the palatopharyngeal sphincter (PPS). The PPS is inferred to play important roles for velopharyngeal closure, but its existence remains controversial and its roles have been regarded as being played by the SCP. The present study aimed to clarify the anatomical status and functional implications of the PPS. MATERIALS AND METHODS: Macroscopic and microscopic examinations were performed on 39 and 4 cadavers, respectively...
