Laparoscopic cholecystectomy has been developed as an alternative to open cholecystectomy for the treatment of symptomatic cholelithiasis. A collaborative study of 261 patients undergoing laparoscopic cholecystectomy at three Texas institutions was performed to determine the effectiveness and safety of this technique. There were 65 males and 196 females(More)
We report on a prospective randomized study of coralline hydroxyapatite (CH) used as backfill for iliac-crest donor sites. Autogenous iliac-crest bone graft is routinely harvested for spinal fusion. Donor-site morbidity is underappreciated; the presumption is that donor sites regenerate. In this study, we assessed the biological viability of the backfill CH(More)
The intense tropical fruit aroma of Sauvignon blanc wines has been associated with the varietal thiols 3-mercaptohexanol (3MH), derived from odorless precursors in the grape, and 3-mercaptohexyl acetate (3MHA), arising from 3MH during fermentation. Grapes and juice were sourced from five locations in Marlborough, New Zealand, taking hand-picked grapes and(More)
CONTEXT Concern exists about the cardiovascular health implications of large size among professional football players and those players who aspire to professional status. OBJECTIVES To assess cardiovascular disease (CVD) risk factors in active National Football League (NFL) players and to compare these findings with data from the Coronary Artery Risk(More)
Computational methods designed to predict and visualize ligand protein binding interactions were used to characterize volatile anesthetic (VA) binding sites and unoccupied pockets within the known structures of VAs bound to serum albumin, luciferase, and apoferritin. We found that both the number of protein atoms and methyl hydrogen, which are within(More)
PURPOSE To retrospectively analyze whether adding a delayed high-resolution dedicated neck F-18 FDG positron emission tomography-computerized tomographic (PET-CT) imaging protocol in patients with recurrent differentiated thyroid cancer increases the number of abnormal foci within the neck. MATERIALS AND METHODS Seventeen PET-CT studies from a total of 10(More)
Tears of the peroneus longus muscle are unusual, and typically involve the distal insertion at the musculotendon junction. Although tears of the mid-portion of the peroneus longus muscle/tendon complex have been reported, no reports of a tear at the origin of the peroneus muscle have been published, to the authors' knowledge. Herein a case of proximal(More)
UNLABELLED Sincalide-stimulated cholescintigraphy is performed to quantify gallbladder contraction and emptying. However, different infusion methods are used for this study. Our purpose was to determine the infusion method with the least variability (smallest coefficient of variation [CV]) for calculation of the gallbladder ejection fraction (GBEF) in(More)
