introduction: an attack of acute myocardial infarction (mi) poses the threat of great damage to cardiac tissue. operative therapeutic modalities such as coronary artery bypass grafting (cabg) may enhance myocardial perfusion in high-grade coronary vasculature occlusions. it has been shown previously that low-level laser therapy (lllt) significantly reduces infarct size following induction of my...

Introduction: By introducing of laser systems and their continuous development, a new chapter of laser systems applications in a variety fields including research and clinical science in addition to the therapeutic, diagnostic applications were available for medical professionals in various fields. Most lasers emit radiation with intrinsic probable risks where in laser-tissue i...

This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...

The response of living tissues to the surgical trauma is associated with varying degrees of tissue repair and involves two distinct processes including replacement and regeneration. Replacement results in scar tissue formation instead of restoration of the normal architecture. However, regeneration leads to restoration of the original architecture leaving no sign of injury. Anti-proliferative a...

INTRODUCTION The Thulium fiber laser may have several advantages over current urology lasers, including smaller size, more efficient operation, improved spatial beam quality, more precise tissue incision, and operation in pulsed or continuous-wave modes. Previous laser-tissue interaction studies utilizing the Thulium fiber laser have been limited to laser powers of less than 5 W, restricting po...

Monte Carlo techniques are the primary method for modeling the behavior of light in biological tissue. They were first applied in this context to modeling the interaction of laser light with tissue in medical applications for the assessment of damage during clinical laser ablation (2). The term Monte Carlo (3) refers to the use of a stochastic simulation to model physical processes. It is well ...
