Abstract   Background: Despite being the largest rotator cuff tendon of the shoulder, the   function and clinical relevance of subscapularis pathology has been largely ignored   in the literature. Although many studies have focused on subscapularis tears recently,   majority of them reported techniques for open repair. The advent of arthroscopy and   arthroscopic repair techniques has opened ...

Background: Impaired DNA repair mechanism is one of the main causes of tumor genesis. Study of intrinsic radiosensitivity of cancer patients in a non-target tissue (e.g. peripheral blood) might show the extent of DNA repair deficiency of cells in affected individuals and might be used a predictor of cancer predisposition. Methods: Initial radiation-induced DNA damage (ratio of Tail DNA/Head DN...

Objective(s): Coronary artery disease (CAD) is the leading cause of death in both male and female worldwide. The main cause of CAD is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. X-ray repair cross-complementing protein 1 (XRCC1) as a ...

different ossificant materials have been used for induction of bone repair in many studies, and bone matrix gelatin which contains bone morphogenic proteins is one of the best ones. in present study we evaluated the role of this material in acceleration of bone repair in rabbit tibia. a hole of 3.5 mm diameter was made on right tibia of 10 and 12 rabbits as study and control group respectively....

Introduction: Porcelain fracture is a relatively common problem in clinical dental practice. Various methods have been proposed for repairing porcelain fractures including direct composite resin repair or construction of a porcelain laminate veneer and its cementation with a resin cement. Evaluation of shear bond strength of porcelain repair methods was the purpose of this study. Methods: Tw...

DNA is a precious molecule. It encodes vital information about cellular content and function. There are only two copies of each chromosome in the cell, and once the sequence is lost no replacement is possible. The irreplaceable nature of the DNA sets it apart from other cellular molecules, and makes it a critical target for age-related deterioration. To prevent DNA damage cells have evolved ela...

introduction: pilonidal sinus is a common disease in sacrococcygeal area, which mostly caught young people and cause disability, which needs complete rest at home and taking off from work. although the surgical treatment of this problem goes back to the last century, still optimal treatment is a controversy. recent studies have raised different surgical approaches, so that there is no general a...
