Hazardous chemicals may enter the body by inhalation, ingestion, injection or dermal absorption. These exposure routes constitute the overall exposure burden on the body. Most occupational exposure studies have focused on measurement of the concentration of air-borne contaminants and other possible routes of exposure are often overlooked.Several studies have already highlighted the importance o...

HNSCC that involves the skin is able to invade the dermal lymphatic system. Currently there is no way to identify patients with dermal lymphatic invasion preoperatively. The purpose of this study is to determine whether CT can predict dermal lymphatic invasion. Medical records, CT scans, and corresponding histopathologic slides were reviewed of HNSCC patients with skin resected as part of their...

Acrylic polymers have broad applications in the manufacture of paints and paper coatings, emulsion adhesives, plastics, lighting, glass replacements, personal care products and even dental fillings. However, acrylic acid and some acrylate oligomers and monomers adversely affect human health as eye and skin irritants. Exposure to monomers occurs primarily in the workplace via inhalation and derm...

background:uncontrolled application of diazinon (dzn)can cause environmental contamination and adverse healtheffects on humans or animals. objectives:this study aimed toinvestigate the toxic effects and the level of dzn in serum andtissues of rabbits following a sub acute dermal exposure totoxicant. methods:different doses of dzn were applied dailyto new zealand rabbits through the ear skin in ...

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...

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...

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...

BACKGROUND Over recent decades, scientists and surgeons have collaborated to develop various bioengineered and synthetic products as an alternative to skin grafts. Despite the numerous articles and reviews written about dermal skin substitutes, there is no general consensus. METHODS This article reviews dermal skin scaffolds used in clinical applications and experimental settings. For scaffol...

BACKGROUND The extracellular matrix (ECM) produced by dermal fibroblasts supports skin structure, and degradation and/or reduced production of ECM are the main causes of wrinkle formation. OBJECTIVE The aim of this study was to identify the active ingredient that enhances ECM production in dermal fibroblasts. METHODS Polarity-based fractionation was used to isolate the active ingredient fro...
