silver salts and nanosilver (ns) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. therefore, in this study, the possible dermal toxicity of ns particles and silver nitrate (agno3), was tested by determining the serum level of transforming growth factor-β1(tgf-β1) and study on of mouse skin tissue. in this study, 30 balb...

statement of problem: various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (sctg) is identified as one of the most successful techniques. recently, acellular dermal matrix allograft (adma) has been developed as a substitute for sctg to avoid removing the palatal connective tissue. purpose: the present study compared the clinical efficienc...

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

Acellular dermal matrices (ADM) are becoming an integral component of immediate implant-based breast reconstruction, providing inferolateral coverage and support of the implant. Currently, five ADM products are available on the market for this purpose. Although their application has resulted in improved aesthetic results with low complication rates, the clinical performance of ADM when radiothe...

Angiogenesis plays an important role in a variety of pathophysiologic processes, including tumor growth and rheumatoid arthritis. We have previously shown that soluble E-selectin (sE-selectin) is an important angiogenic mediator. However, the mechanism by which sE-selectin mediates angiogenesis is still unknown. In this study, we show that sE-selectin is a potent mediator of human dermal microv...

To understand the mechanisms underlying 15(S)-hydroxyeicosatetraenoic acid [15(S)-HETE]–induced angiogenesis, we studied the role of Egr-1. 15(S)-HETE induced Egr-1 expression in a time-dependent manner in human dermal microvascular endothelial cells (HDMVECs). Blockade of Egr-1 via forced expression of its dominant-negative mutant attenuated 15(S)-HETE–induced HDMVEC migration and tube formati...

Objective. To observe the dermal microcirculation blood perfusion characterization of meridians channels (acupoints). Methods. 20 healthy human subjects were monitored using Pericam Perfusion Speckle Imager (PSI) for the changes in dermal microcirculation blood perfusion on governor meridian and other respective dermal regions as a control. Result. The microcirculation blood perfusion on Govern...
