“Hepatic stellate cells (HSCs) have demonstrated a strong T-cell inhibitory activity. In a mouse islet transplantation model, cotransplanted HSCs can protect islet allografts from rejection. The involved mechanism is Pifithrin-�� in vitro not fully understood. We showed in this study that expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), an important

apoptosis-inducing ligand, on HSCs was crucial in protection of islet allografts, since HSCs derived from TRAIL knockout mice demonstrated less inhibitory activity towards T-cell proliferative responses, and substantially lost their capacity in protecting cotransplanted islet allografts from rejection, suggesting that TRAIL-mediated T cell apoptotic death is important in HSC-delivered immune regulation activity. © 2009 Wiley-Liss, Inc.

“In this report, we present a case of a prelaminated radial forearm flap in reconstruction of a large persistent cleft palate with transoral single arterial and three venous anastomoses. A 17-years-old female patient presented a large cleft palate defect and complete dentition, dysmelia of both arms and bilateral thumb aplasia. A radial flap was prelaminated using oral mucosa 5 days prior to transplantation. Five days after flap prelamination, the facial artery and vein, submandibular vein, and a venous branch to the masseter TSA HDAC concentration muscle behind the buccinator muscle

fibers were exposed through an intraoral incision lateral to the inferior right mucogingival junction. The radial artery, its bilateral accompanying veins, and the cephalic vein see more of transplanted flap were anastomosed transorally to the facial vessels, submandibular vein, and masseter branch. The vessel pedicle ran through the palatoglossal arch dorsal to the second upper molar. Good flow and flap perfusion were evinced, and further-on successful healing was achieved. The case encourages similar treatment in comparable situations avoiding

facial nerve hazard and extraoral scars. © 2013 Wiley Periodicals, Inc. Microsurgery 34:229–232, 2014. “
“In this report, we describe the technique of muscle and nerve sparing latissimus dorsi (LD) flap and evaluate the outcomes of reconstruction of various defects with 12 free and 2 pedicled muscle and nerve sparing LD flaps in 14 patients. The LD muscle functions at operated and nonoperated muscles were evaluated clinically and with electroneuromyography. All flaps survived completely but one which had a partial necrosis. The mean follow-up time was 12.3 months. Adduction and extention ranges of the shoulders were the same bilaterally in all patients. In electroneuromyography, no significant difference was available statistically between the sides. This muscle and nerve sparing latissimus dorsi flap has advantages of thinness, muscle preservation and reliability, and thus can be a good option to other fasciocutaneous flaps in reconstruction surgery. © 2011 Wiley Periodicals, Inc.
