[Purpose] To determine the efficacy of high intensity laser therapy (HILT) versus pulsed electromagnetic field (PEMF) in the treatment of primary dysmenorrhea. [Subjects and Methods] This was a randomized clinical trial that included 52 girls diagnosed with primary dysmenorrhea and who were assigned randomly into two groups of equal numbers. The treatment was three sessions every cycle for thre...

Perfluorocarbon nanoemulsions (PFCNEs) have recently been undergoing rigorous study to investigate their ability to improve the therapeutic efficacy of tumor ablation by high intensity focused ultrasound (HIFU). For precise control of PFCNE delivery and thermal ablation, their accumulation and distribution in a tumor should be quantitatively analyzed. Here, we used fluorine-19 (19F) magnetic re...

Tissue destruction by thermal ablation occurs when the targeted delivery of heat or cold causes a rapid change in temperature (>55°C for heat or <−20–50°C for cold) in the local tissue environment. Imaging can be used to localize and target the thermal effects to the target/tumor for treatment, control the energy deposition, and assess treatment response. Therapeutic applications of ultrasound ...

A petawatt-class laser system has been developed and laser intensity has recently reached a level as high as 10 22 W/cm 2 owning to the great progress in chirped pulse amplification (CPA) technique. Such ultrahigh intense laser pulses provide powerful tools for laser-matter interaction experiments in the relativistic regime. In these plasma-creating experiments, laser pulses with high temporal ...

Akbari A1 1. Assistant Professor, Department of Physiotherapy, Faculty of Medicine, Zahedan University of Medical Sciences Abstract Background: Shoulder pain is the third most prevalent cause of musculoskeletal disorder after low back and cervical pains. Most of the shoulder symptoms are attributed to the rotator cuff. The objective of this study was to compare the effects of low-power ...

In an effort to understand dynamic optical changes during laser interstitial thermal therapy (LITT), we utilize the perturbative solution of the diffusion equation in heterogeneous media to formulate scattering weight functions for cylindrical line sources. The analysis explicitly shows how changes in detected interstitial light intensity are associated with the extent and location of the volum...

background: low-intensity laser therapy (lilt) can be utilized for different treatments in the fi eld of orthodontics and dentofacial orthopedics. the aim of the present study was to evaluate the effi cacy of lilt on (1) the rate of canine movement during canine retraction phase and (2) evaluate the radiographic changes occurring during lilt around the irradiated area. materials and methods: a ...
