Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...

Background: The theory of selective photo-thermolysis led to the development of a variety of different laser systems which range from the shorter spectrum of 694nm ruby laser to the middle with the 755nm alexandrite and 810nm diode lasers to the long end with the 1064nm (Nd:YAG) laser. Objective: A systematic review on the clinical trials with use of various laser sources for hair removal...

Damage of the normal tissue is a serious concenrn in cancer treatment. Hyperthermia by laserhas been considered as a safe cancer treatments methods with lower harmful effects on normaltissues. Using nanoparticles in cancer treatment has improved laser therapy, which is based ona selective cell targeting method to localize cell damages. Metallic nanoparticles such as gold,silver, and copper have...

Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...

Background: Treatment of vitiligo remains an attractive topic and several therapies with varying degrees of success have been used. The aim of this study was to find out whether the combination of topical calcipotriol and excimer laser increases the efficacy of therapy compared to excimer laser alone. Methods: Twenty eight patients in two groups were treated with 308nm excimer laser alone (14 p...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

Background: Laser treatment is a rapid, non-invasive procedure for long-term hair removal. Lasers operate based on the principle of selective photothermolysis and target melanin in the hair follicle. We intend to determine the level of hirsute patient satisfaction with the alexandrite laser hair removal procedure.Methods: In this cross-sectional study 82 hirsute patient...

Introduction: In laser surgery, the laser beam can evaporate and cut the tissue like a small surgical knife when the tissue temperature is heated to 100 degrees Celsius. a complete understanding of the distribution of damage in both pathologic tissue and surrounding tissue is necessary. Although the test is the most realistic solution for treating medical problems, for this rea...
