BACKGROUND Incisional hernias with history of recurrence or infection remain a challenge, with high postoperative morbidity and recurrence rates. The purpose of this study is to evaluate outcomes of patients treated with human cadaveric acellular dermis as an adjunct to abdominal wall reconstruction. METHODS We retrospectively reviewed 39 abdominal wall(More)
A clinical trial comparing ibuprofen, 400, 600, and 800 mg, with aluminum ibuprofen, 400 mg, and placebo was conducted in patients with moderate or severe pain subsequent to third molar extraction. Pain intensity ratings and ibuprofen serum levels were obtained at baseline, 30 minutes, 1 hour, and hourly thereafter for 3 hours. Pain intensity ratings were(More)
Our objective was to determine the value of caffeine in combination with acetaminophen in the relief of pain from uterine cramping, episiotomy, and third molar extraction. In the dental study, 173 patients received two or four tablets of 500 mg acetaminophen or the combination of 500 mg acetaminophen and 65 mg caffeine. In the three postpartum studies, 1345(More)
Initial biosynthetic radiolabelling experiments with cultured granulosa cells revealed the presence of an oligosaccharide-phosphatidylinositol (glycosyl-phosphatidylinositol; (Ose)nPtdIns) structurally related to (Ose)nPtdIns-lipids isolated from other cell types. Prolactin (PRL) stimulated [3H]glucosamine-(Ose)nPtdIns turnover and the rapid generation of(More)
Single hepatocytes microinjected with aequorin generate free Ca oscillations when stimulated by agonists such as phenylephrine or vasopressin. Here we show that caffeine by itself does not elicit any significant change in free Ca, nor it does lower the threshold concentration of an agonist needed to induced spikes. In contrast, both caffeine and(More)
Ibuprofen is a peripherally acting nonsteroidal anti-inflammatory drug indicated fo ranalgesia, antipyresis, and various arthritic conditions. A solubilized 200 mg liquigel formulation of ibuprofen has been shown to have a more rapid rate of absorption compared with ibuprofen 200 mg tablets. Ibuprofen liquigels have a kinetic profile similar to ibuprofen(More)
Inositol-phosphoglycan (IPG) is a putative mediator of insulin action that has been shown to affect numerous biochemical processes. IPG, prepared from liver membranes, promptly inhibited phenylephrine- or vasopressin-induced [Ca2+]i oscillations when perfused over Fura-2-dextran injected rat hepatocytes. An antibody to IPG suppressed the inhibitory effect(More)
Testicular cells from adult hypophysectomized rats were cultured for 10 or 12 days, and the effect of treatment with hCG (10 ng/ml) on testosterone and progesterone production and the activity of the Leydig cell enzyme, 3 beta-hydroxysteroid dehydrogenase, were studied. Regardless of hormone treatment, on 4th day in culture a decline in the steroidogenic(More)
Single rat hepatocytes microinjected with the photoprotein aequorin generate oscillations in the cytosolic free Ca2+ concentration ([Ca2+]i) when stimulated with agonists acting through the phosphoinositide signalling pathway. We show here that, in single rat hepatocytes, bovine growth hormone (bGH) is able to induce [Ca2+]i oscillations which display(More)
The relative analgesic efficacy and safety of single oral doses of 50 and 100 mg of flurbiprofen (Ansaid, Upjohn) were compared with 100 mg of zomepirac sodium, 650 mg of acetaminophen plus 60 mg of codeine, 650 mg of acetaminophen alone, and placebo in a randomized, double-blind, parallel-group study. A total of 182 patients entered the study with moderate(More)
