Objectiv e- To eval uate the effects of Artemisia sieberi extract on experimental dermal wounds healing .Design- Experimental study.Animals- 30 male Spragne-Dawly rats.Procedures- Two uniform 7 mm diameter skin defect were created on the back of each animal by skinpunch (total of 60 wounds). Then, the extract of the plant was applied once daily on half of the wounds forhistopathological and bio...

objective(s):various methods for repairing bone defects are presented. cell therapy is one of these methods. bone marrow stromal cells (bmscs) seem to be suitable for this purpose. on the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. materials and me...

BACKGROUND The newest generation of meniscus repair devices is designed to combine the benefits of the all-inside technique with the biomechanical properties of sutures. HYPOTHESIS New flexible all-inside suture anchors have better fixation strength than rigid anchors, but there is no difference when compared to conventional horizontal and vertical mattress sutures. STUDY DESIGN Controlled ...

Introduction: The biomechanical screw performance plays a crucial role on the early interfragmentary stability and, in turn, on the fracture healing outcome. Therefore, this study compares the biomechanical performance of the cannulated headless compression screws Fixos Ø4.0, 5.0 & 7.0 mm to the standard cannulated compression screws Asnis III. Materials & Method: Interfragmentary compression f...

INTRODUCTION: Mechanical analogue composite bone models have been used as cadaveric bone substitutes in a wide variety of biomechanical tests. The objective of this study was to validate the diaphyseal structural properties in terms of flexural rigidity, ultimate bending strength, axial stiffness, ultimate compression strength, ultimate torsional strength, torque angle at ultimate torsional str...

Distal fibula fractures are the most common injury of weight bearing bones. Several studies have shown the benefit of locking plates especially in osteoporotic bone. The aim of this biomechanical study was to test the anatomically shaped VariAx Distal Lateral Fibula Plate in comparison to a commonly used 1/3 Tubular Plate. The implants were assembled to bone surrogates simulating a comminuted f...

Freeze-drying and gamma irradiation are the techniques widely use in tissue banking for preservation and sterilization of tissue grafts respectively. However, the effect of these techniques on biomechanical properties of bovine pericardium is poorly known. A total of 300 strips of bovine pericardium each measured 4 cm 1 cm were used in this study to evaluate the effect of freeze-drying on biome...

STUDY DESIGN Single-cohort descriptive and correlational study. OBJECTIVES To investigate the relationships between tendon pathology, biomechanical measures, and self-reported pain and function in individuals with chronic lateral epicondylosis. BACKGROUND Lateral epicondylosis has a multifactorial etiology and its pathophysiology is not well understood. Consequently, treatment remains chall...

Purpose To investigate ex vivo potentially different corneal biomechanical properties after small-incision lenticule extraction (SMILE) versus LASIK for myopic correction. Methods Thirty human donor corneas were subjected to either myopic SMILE or femtosecond laser-assisted LASIK. Donor corneas were assigned to six investigative groups: Group A, -3.00 D (diopters) SMILE; Group B, -8.00 D SMIL...
