A lack of oxygen is classically described as a major cause of impaired wound healing in diabetic patients. Even if the role of oxygen in the wound healing process is well recognized, measurement of oxygen levels in a wound remains challenging. The purpose of the present study was to assess the value of electron paramagnetic resonance (EPR) oximetry to monitor pO2 in wounds during the healing pr...

Wound healing is a complex biological process involving the interaction of many cell types to replace lost or damaged tissue. Although the biology of wound healing has been extensively investigated, few studies have focused on the role of mast cells. In this study, we investigated the possible role of mast cells in wound healing by analyzing aspects of cutaneous excisional wound healing in thre...

Adverse effects of wound healing, such as excessive scar tissue formation, wound contraction, or nonhealing wounds represent a major clinical issue in today's healthcare. Transforming growth factor (TGF)-beta3 has specifically been implicated in wound healing. Our hypothesis was that local administration of TGF-beta3 to excisional dermal wounds would diminish wound contraction and scar formatio...

In adult human skin, the expression of the extracellular matrix glycoprotein tenascin is limited. Under hyperproliferative conditions such as psoriasis and epidermal tumours, dermal tenascin expression is strongly upregulated. The aim of this study was to investigate the pattern and kinetics of tenascin expression in human skin during wound healing and to address the question of whether keratin...

Physical training influences the cells and mediators involved in skin wound healing. The objective of this study was to determine the changes induced by different intensities of physical training in mouse skin wound healing. Ninety male C57BL6 mice (8 weeks old, 20-25 g) were randomized into three physical training groups: moderate (70% VO2max), high (80% VO2max), and strenuous intensity (90% V...

Background: 2,3-dimethylquinoxaline (DMQ) is a naturally occurring compound with documented antifungal activity. It showed also good in vitro physicochemical and pharmacokinetic characteristics.
 Methods: The wound healing activity of 1% DMQ hydrogel healthy adult male Wister rats were evaluated using the excision model. On day 7, mean percentage closure area was determined. animals sacrif...

Dasatinib, a tyrosine kinase inhibitor, has been shown to produce anti-inflammatory activity and impair vascular integrity in vivo, including during skin wound healing, potentially promoting the repair process. Given that dasatinib is lipophilic small molecule capable of penetrating skin, topical might provide benefits healing. In present study, we investigated impact ointments healing mice. A ...

The effects of ambient temperature (13.50C, 21°C, 30°C) and type of wound on healing of skin wounds were evaluated in common garter snakes (Thamnophis sirtalis). Linear unsutured incisions and circular excisional wounds were evaluated grossly and microscopically in three snakes held at each temperature at each of two, fi've and ten days after surgery. Linear sutured and unsutured incisions and ...
