Ischemia complicates wound closure. Here, we are unique in presenting a murine ischemic wound model that is based on bipedicle flap approach. Using this model of ischemic wounds we have sought to elucidate how microRNAs may be implicated in limiting wound re-epithelialization under hypoxia, a major component of ischemia. Ischemia, evaluated by laser Doppler as well as hyperspectral imaging, lim...

In this study, we hypothesize that local sustained release of vascular endothelial growth factor (VEGF), using adenovirus vector (ADV)-mediated gene transfer, accelerates experimental wound healing. This hypothesis was tested by determining the specific effects of VEGF(165) application on multiple aspects of the wound healing process, that is, time to complete wound closure and skin biomechanic...

The surface of the eye actively suppresses inflammation while maintaining a remarkable capacity for epithelial wound repair. Our understanding of mechanisms that balance inflammatory/reparative responses to provide effective host defense while preserving tissue function is limited, in particular, in the cornea. Lipoxin A4 (LXA4) and docosahexaenoic acid-derived neuroprotectin D1 (NPD1) are lipi...

OBJECTIVE AND BACKGROUND DATA Polarized light has already been experimentally and clinically used in an effort to promote wound healing, but the findings have been equivocal. The aim of this study was to evaluate the effect of visible and infrared polarized light of a specific range of wavelength (580-3400 nm) on the secondary healing of full-thickness skin wounds in rats. MATERIALS AND METHO...

OBJECTIVE To investigate the use of a topical oxygen emulsion (TOE), consisting of a supersaturated oxygen suspension using perfluorocarbon components, on second-degree burns and partial-thickness wounds. DESIGN Oxygen is a required substance for various aspects of wound repair, and increased oxygen tension in a wound has been shown to stimulate phagocytosis and to reduce the incidence of wou...

Wound healing requires a complex series of reactions and interactions among cells and their mediators, resulting in an overlapping series of events including coagulation, inflammation, epithelialization, formation of granulation tissue, matrix and scar formation. Cytokines and chemokines promote inflammation, angiogenesis, facilitate the passage of leukocytes from circulation into the tissue, a...

PURPOSE To report the results of the management of painfully symptomatic postoperative bullous keratopathy (PBK) by performing a nonpreserved human amniotic membrane (NP-AMT) transplantation in nine eyes with poor visual potential. METHODS A prospective, comparative, nonrandomized management of symptomatic PBK was done by performing a complete corneal de-epithelialization followed by a NP-AMT...
