Two monoclonal antibodies to type IV collagen showed a marked decrease in the labeling of the dermal-epidermal junction of neonatal foreskin while the basement membrane around dermal blood vessels was brightly stained. In contrast, these antibodies labeled the junction and dermal blood vessels with approximately equal intensity when adult skin of nonforeskin site was used as substrate. Other an...

objective(s): nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. in this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice.  materials a...

excessive alveolar bone resorption is commonly found when teeth are extracted. this is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician. use of acellular dermal matrix graft is an appropr...

Nanosilver has recently been recognized as an antimicrobial agent. Although this nanoparticlecan be used in medical applications but its dermal and systemic toxicity via dermal exposure hasnot been completely determined yet. The aim in this study was to investigate the potential dermaltoxicity of Nanosilver in subchronic method. Before the colloidal silver nanoparticle toxicityevaluation, their...

Limited research has been conducted on dermal exposure and risk assessment, owing to the lack of reliable measurement techniques and data for quantitative risk assessment. We investigated the magnitude of dermal exposure to jet propulsion fuel 8 (JP-8), using naphthalene as a surrogate, on the US Air Force fuel-cell maintenance workers. Dermal exposure of 124 workers routinely working with JP-8...

INTRODUCTION Increased levels of genes in the type I interferon (IFN) pathway have been observed in patients with systemic sclerosis (SSc), or scleroderma. How type I IFN regulates the dermal fibroblast and its participation in the development of dermal fibrosis is not known. We hypothesized that one mechanism by which type I IFN may contribute to dermal fibrosis is through upregulation of spec...

BACKGROUND Acellular dermal matrix has been increasingly accepted in prosthetic breast reconstruction. Observed benefits include improved control and support of implant position, better implant coverage, and the suggestion of a decreased capsular contracture rate. Based on this positive experience, it is not surprising that acellular dermal matrix would be applied to other challenging implant-r...

1 Sir: I reconstructive breast surgery, skin-flap quality is an important determinant of surgical outcome. Although the overall rate of complications is low in breast surgery,1 some patient cohorts may be associated with a significantly higher risk of wound complications.2,3 Lin et al2 found that breast reconstruction in irradiated wound beds has been associated with a greater than 3-fold incre...
