Introduction: Nowadays, skin flaps are used to repair wounds, skin lesions and in reconstructive surgeries. In this way, the main problem is loss of flap tissue and necrosis, due to processes that result from ischemia-reperfusion injury and reactive oxygen species. Eupatilin is an O-methylated flavone derived from Artemisia plants that demonstrates anti-inflammatory, anti-oxidative, and anti-tu...

 ABSTRACT Background: The transverse rectus abdominis musculocutaneous (TRAM) flap remains the gold standard for postmastectomy reconstruction either immediate or delayed. However, transfer of TRAM flap can be associated with donor site morbidities and complications in flap. A successful reconstruction consists of careful patient selection, surgical technique and meticulous preoperative plannin...

Introduction: The standard methods for reconstruction of soft tissue defects in legs are gastrocnemius flap for proximal third defects, soleus flap for middle third and free flap in the distal third. However, there are problems with the use of free flap, like increased operative time, damage of major vessels and the need for experienced microsurgeon. In this study we examined the ability of the...

The prediction of aerodynamic characteristics and smart flap of airfoil under the ground effect are carried out by the integration of computational fluid dynamics. Considering different types of beams, a parametric bending profile of a smart flap is designed. Cantilever beam with uniformly varying load with roller support at the free end is considered in here. A pressure-based implicit procedur...

BACKGROUND Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Rec...

Background and purpose: Due to the properties of Stevia, it seems that this plant can be effective in reducing oxidative damage consequent to ischemia-reperfusion, and increase the survival of skin flap. This research aimed at investigating the effects of oral extract of stevia on apoptosis and skin flap necrosis in rats. Materials and methods: In this experimental study, Sprague Dawley rats w...
