Background: Acupuncture is an indispensable part of traditional Chinese medicine for relief of pain. The purpose of this study was the immediate & latent of low power LASER Ga-Al-As irradiation applied to acupuncture points on experimental pain threshold. Methods: This quasi-experimental study was conducted on seventy adult women ranging from 20 to 40 years old assigned randomly into two groups...

308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet b radiation system consisting of a noble gas and halide. the aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating ...

We synthesized tunable far-infrared radiation at frequencies higher than 9 THz (300 cm (-1)) by mixing CO(2) laser, (15)NH(3) laser, and microwave radiation in a W-Co metal-insulator-metal diode. We used this farinfrared radiation to accurately measure torsion-rotation transitions of CH(3)OH in the 8-9-THz region. We also measured the frequency of the aP(7, 3) (15)NH(3) laser transition.

Plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. Anthocyanin is affected by a variety of factors. Light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. Here, we have investigated the influence of the blue laser-diode (BLD) and red laser-He Ne (...

Space radiation is a great danger to electronics and astronauts onboard space vessels. The spectral flux of space electrons, protons and ions for example in the radiation belts is inherently broadband, but this is a feature hard to mimic with conventional radiation sources. Using laser-plasma-accelerators, we reproduced relativistic, broadband radiation belt flux in the laboratory, and used thi...

introduction: in this study the effects of low power helium-neon laser radiation on the cell population of open skin full thickness wound of rats were investigated from histological and biomechanical point of views. materials and methods: 90 male rats were randomly divided into control and two experimental groups. under general anesthesia and sterile conditions around open full thickness skin w...

The Discrete Ordinates Method (DOM) for solving transient radiation transfer equation in cylindrical coordinates is developed for radiation heat transfer in participating turbid media in pico-scale time domain. The application problems addressed here are laser tissue welding and soldering. The novelty of this study lies with the use of ultrashort laser pulses as the irradiation source. The char...
