The free fibular osteocutaneous flap is often used in the reconstruction of composite oromandibular defects. In contrast, the lateral calcaneal flap has never been used in oromandibular reconstruction. On the basis of their anatomic continuity, the authors combined the free fibular osteocutaneous flap with the lateral calcaneal skin paddle to obtain 2(More)
BACKGROUND The aim of this study was to evaluate the recurrence pattern after skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) using transverse rectus abdominis musculocutaneous (TRAM) flap in patients with invasive breast cancer. METHODS From 1995 to 2010, patients with invasive breast cancer who underwent SSM followed by IBR using(More)
BACKGROUND The thoracodorsal artery perforator flap was first introduced in 1995. Many authors focused on using anatomical landmarks to identify skin perforators and on thinning procedures for a skin paddle. In this study, we used the superthin free thoracodorsal artery perforator flap for resurfacing shallow defects of the extremities in 10 patients. (More)
The effect of the carcinogen safrole on intracellular Ca2+ movement has not been explored in osteoblast-like cells. This study examined whether safrole could alter Ca2+ handling and viability in MG63 human osteosarcoma cells. Cytosolic free Ca2+ levels ([Ca2+]i) in populations of cells were measured using fura-2 as a fluorescent Ca2+ probe. Safrole at(More)
BACKGROUND Early colloid resuscitation in major burn patients has been stopped because of its deteriorating effect on thermal injury-induced vascular hyperpermeability. We hypothesized that inhibition of inducible nitric oxide synthase (iNOS) to stabilize endothelial permeability and to retain colloid solution in the vascular space will reverse its effect(More)
Capsazepine is thought to be a selective antagonist of vanilloid type 1 receptors; however, its other in vitro effect on different cell types is unclear. In human MG63 osteosarcoma cells, the effect of capsazepine on intracellular Ca(2+) concentrations ([Ca(2+)](i)) and cytotoxicity was explored by using fura-2 and tetrazolium, respectively. Capsazepine(More)
OBJECTIVE To determine whether inhibition of inducible nitric oxide synthase to stabilize endothelial permeability and to retain hypertonic saline in the vascular space will ameliorate burn-induced gut barrier dysfunction. DESIGN Prospective, experimental study. SETTING Research laboratory at a university hospital. SUBJECTS Thermal injury models in(More)
The effect of the oxidizing agent thimerosal on cytosolic free Ca(2+) concentration ([Ca(2+)]i) and proliferation has not been explored in human osteoblast-like cells. This study examined whether thimerosal alters Ca(2+) levels and causes cell death in MG63 human osteosarcoma cells. [Ca(2+)]i and cell death were measured using the fluorescent dyes fura-2(More)
HYPOTHESIS The use of albumin in the early resuscitation formula after major burn has been forbidden because of its damaging effect on the gut barrier function. We hypothesize that inhibition of the inducible isoform of nitric oxide synthase to stabilize endothelial permeability and to retain albumin in the vascular space will ameliorate the major(More)
Although autogenous tissue can be used to replace unsatisfactory prosthetic breast reconstructions in mastectomy patients, because of the magnitude, complexity, and many potential complications associated with the procedure, combined with a long-term recovery, the use of an implant to replace the mastectomy defect is still the most common method for(More)
