OBJECTIVE To investigate the effect of therapeutic infrared class 3B laser irradiation on skin temperature in healthy participants of differing skin color, age, and gender. BACKGROUND Little is known about the potential thermal effects of Low Level Laser Therapy (LLLT) irradiation on human skin. METHODS Skin temperature was measured in 40 healthy volunteers with a thermographic camera at la...

PETALO (Positron Emission Tof Apparatus with Liquid xenOn) is a novel concept for positron emission tomography scanners, which uses liquid xenon as scintillation medium and silicon photomultipliers readout. The large yield the fast time of xenon, well its scalability, makes it an excellent candidate PET scanners Time-of-Flight measurements, especially total-body machines. A first prototype full...

BACKGROUND Although several studies have demonstrated the effects of low-level laser therapy (LLLT) on skin flap viability, the role of higher doses has been poorly investigated. OBJECTIVE To investigate the inhibitory effect of the LLLT (λ=670 nm) on the viability of random skin flaps in a rat model using an irradiation energy of 2.79 J at each point. METHODS Sixteen Wistar rats were rando...

PURPOSE In recent years experimental data have indicated that low-energy proton beam radiation might induce a difference in cellular migration in comparison to photons. We therefore set out to compare the effect of proton beam irradiation and X-rays on the survival and long-term migratory properties of two cell lines: uveal melanoma Mel270 and skin melanoma BLM. MATERIALS AND METHODS Cells tr...

Early changes in the vascularity of grafted skin after X-ray irradiation were evaluated using the microangiographic technique. There was a correlation betweeen the vascular density at the time of irradiation and the vascular density two weeks after irradiation. The grafts irradiated in the early hypovascular stage showed mild-moderate vascular reactions to irradiation, whereas those irradiated ...

Background: Normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. Cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. The aim of t...

In this work we focus on the emitter formation and its dopant source, the PhosphoSilicate Glass (PSG), formed by POCl3 diffusion. An optimum emitter requires an exact adjustment of diffusion parameters, such as process temperature, time, POCl3-N2 gas flow and O2 gas flow. Another important process parameter which is normally kept constant but also has a strong influence on PSG and emitter forma...

Most advice currently available with regard to fluoroscopic skin reactions is based on a table published in 1994. Many caveats in that report were not included in later reproductions, and subsequent research has yielded additional insights. This review is a consensus report of current scientific data. Expected skin reactions for an average patient are presented in tabular form as a function of ...

Introduction:Targeted radionuclide therapy (TRT) has been demonstrated to be an effective therapeutic tool in patients with disseminated bone metastasis. TRT is generally performed with a single radionuclide. In this study we investigated the feasibility of combined TRT with a high-energy beta emitter (153Sm) and a low energy beta emitter (177Lu) in wistar...
