Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...
In this paper, modulation bandwidth characteristics of InGaAs/GaAs quantum dot (QD) laser were theoretically investigated. Simulation was done by using the fourth order Runge-Kutta method. Effect of carrier relaxation life time, temperature and current density on characteristics of tunneling injection QD laser (TIL) and conventional QD laser (CL) were analyzed. Results showed that tunneling inj...
In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...
Background: To assess the effectiveness of repeated transvaginal ultrasound-guided ovarian interstitial laser treatment in the management of anovulatory patients with polycystic ovary syndrome (PCOS). Materials and Methods: A retrospective study was performed in our department on 27 anovulatory PCOS women who failed to respond to the first ultrasound-guided transvaginal ovarian interstitial las...
Diffusion processes in the normal and laser-coagulated squirrel monkey retina were studied by electron microscopy and peroxidase tracer techniques. In a group of monkeys, the right eye was coagulated with an American Optical Ruby laser. Two to three weeks later, peroxidase was injected through the pars plana, close to the surface of the retina, in both eyes of each animal. The animals were then...
Control the laser beam hazards for class IIIB and IV laser is concluded: engineering and executive controls. In executive control, when laser beam enters to the free space, the controlled area must be identified to protect people and control the radiation exposure limits. Given the fact that the laser light of the laser is entering the environment, the identification of the area under control i...
The current standard recommendation for antibiotic therapy in the management of chronic osteomyelitis is intravenous treatment for six weeks. We have compared this regime with short-term intravenous therapy followed by oral dosage. A total of 93 patients, with chronic osteomyelitis, underwent single-stage, aggressive surgical debridement and appropriate soft-tissue coverage. Culture-specific in...
PURPOSE The aim of this sutdy was to demonstrate the selective localization of a new photosensitizer, zinc phthalocyanine tetrasulfonate (ZnPcS(4)), in rat eyes and investigate the ability of ZnPcS(4) to produce a photochemical closure of experimental choroidal neovascularization (CNV) upon irradiation with a 670-nm laser light. METHODS To determine the biodistribution of ZnPcS(4) and the opt...
Zinc oxide (ZnO) nanoparticles have received growing attention for several biomedical applications. Nanoparticles proposed for these applications possess the potential to interact with biological components such as the blood, cells/ tissues following their administration into the body. Hence we carried out in vivo investigations in Swiss Albino Mice to understand the interaction of ZnO nanorods...
Background: Children with idiopathic thrombocytopenic purpura who are treated with intravenous immunoglobulin therapy might experience a decline in their absolute neutrophil count. The aim of this study was to investigate the incidence of neutropenia following intravenous immunoglobulin therapy in children with idiopathic thrombocytopenic purpura undergoing intravenous immunoglobulin therapy. ...
