Background: In 2005, we designed and evaluated the effectiveness of the transvaginal ultrasound-guided ovarian interstitial laser treatment in twenty-three anovulatory women with clomifene citrate (CC)-resistant polycystic ovary syndrome (PCOS) as a new method of ovulation induction in infertile PCOS women, with a more than 80% ovulation rate and 36% pregnancy rate during six postoperative mont...

Background and aim : The clinical management of verrucae vulgaris is often challenging and no treatment is always effective. Early studies have suggested that pulsed-dye laser (PDL) may be highly effective in the treatment of verrucae through obliteration of dilated vessels in papillary dermis. The objective of this study was to compare safety and efficacy of 585 nm with 595 nm PDL in the...

Background: Skin cancer is the most prevalent type of cancer and melanoma is the deadliest kind of skin cancer in the world. Due to enhanced induction of apoptosis and ROS levels, low-level lasers can be utilized to destroy skin cancer cells. Lasers are used to treat some skin lesions. Vitamin A is beneficial in the prevention and treatment of skin cancer. Vitamin A inhibits the pathway of canc...

Introduction: Endovenous laser treatment (ELT) is a new treatment method for the reflux of the great saphenous vein. A successful ELT is dependent on the selection of optimum parameters required to achieve optimal vein damage while avoiding side effects including skin burns. The mathematical modeling of ELT can be used to understand the process of ELT. This study was conducted to examine the ef...

Objective(s): Photo-thermal therapy (PTT) is a therapeutic method in which photon energy is converted into heat to induce hyperthermia in malignant tumor cells. In this method, energy conversion is performed by nanoparticles (NPs) to enhance induced heat efficacy. The low-cytotoxicity and high optical absorbance of NPs used in this technique are very important. In the present study, titanium di...

background and aims. er:yag laser irradiation has been claimed to improve the adhesive properties of dentin; therefore, it has been proposed as an alternative to acid etching. the aim of this in vitro study was to investigate the shear bond strength of an etch-and-rinse adhesive system to dentin surfaces following er:yag laser and/or phosphoric acid etching. materials and methods. the roots of ...

background  recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (lllt). the aim of this study was to determine whether lllt could induce a bio-stimulatory effects on human gingival fibroblasts (hgf3-pi 53). therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type i gene e...

introduction: with the rapid increase in use of lasers in medical treatments, it is important to understand the mechanisms of heat transfer in biological tissues in order to minimize damage to the tissues resulting from extra heat applied. the aim of this study is to investigate the temperature distribution in living biological tissues when laser irradiation is used in a treatment. methods:  in...

introduction: vitiligo is a cutaneous disorder of pigmentation, for which, there are some proven modalities of treatment. in this study, we evaluated the efficacy of the addition of topical pimecrolimus to 308nm excimer laser in reducing treatment duration and improving the response rate of eyelid vitiligo, compared with 308nm excimer laser monotherapy. methods: fifty two symmetrically localize...
