Aim of the work was an investigation of ureter wall perforation possibility by various types of mid-infrared radiations (from 2.01 μm (Tm:YAG) up to 2.94 μm (Er:YAG)) and exploration of the interaction basic characteristic for ureter surface (epithelium) and its deep structures (mesenchym). From results follow that CTH:YAG, Er:YAG, and CTE:YAG laser radiations accomplish a good wall ureter perf...

Micro size craters were created by interaction of nanosecond laser beam with titanium target in liquid media. The dimension of crater i.e. depth and width is important in some applications such as micromachining. When the interaction occurs in liquid environment, the ablated materials from the target expand into the liquid. The ablated material can affect the interaction process if the ablated ...

BACKGROUND The use of the laser as an auxiliary tool has refined the traditional technique for lipoplasty. During laser lipolysis, the interaction between the laser and the fat produced direct cellular destruction before the suction, reduced bleeding, and promoted skin tightening. OBJECTIVE This study sought to perform a comparative histologic evaluation of laser lipolysis with the pulsed 106...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...

introduction: we investigated the characteristic of a suitable irradiation on skin's tensional strength using design of experiments (doe). the experiments in this research are designed in two phases and data envelopment analysis (dea) is used for performance measurement of each phase. material and methods: samples were provided from pleura as surface tissue made of collagen and elastin fib...

During laser irradiation of biological tissue, a number of physical processes take place that determine temperature elevation and thermal damage rates. Some of those important to laser–tissue interaction are: 1) propagation of light in scattering media; 2) transformation of laser light into photochemical, acoustic, or thermal energy; 3) tissue–tissue and tissue–environment heat and mass transfe...

introduction: to investigate the ultrastructural changes of dentin irradiated with 980-nm diode laser under different parameters and to observe the morphological alterations of odontoblasts and pulp tissue to determine the safety parameters of 980-nm diode laser in the treatment of dentin hypersensitivity (dh). methods: twenty extracted human third molars were selected to prepare dentin discs. ...

Introduction: Laser tissue soldering using albumin and indocyanine green dye (ICG) is an effective technique utilized in various surgical procedures. The purpose of this study was to perform laser soldering of rat skin under a feedback control system and compare the results with those obtained using standard sutures. Material and Methods: Skin incisions were made over eight rats’ dorsa, which w...
