Granuloma faciale (GF) is a rare cutaneous disorder categorized as a localized form of small-vessel vasculitis. Clinically, it manifests as single or multiple well-demarcated red-brown plaques, papules and nodules, nearly always confined to the face. Herein, we report a 39-year-old man with multiple red-brown infiltrated plaques on face and extrafacial lesions on back, shoulders and both arms. ...

Ultra-pulsed fractional CO2 laser is an efficient, precise, and safe therapeutic intervention for skin refreshing, although accompanied with prolonged edema and erythema. In recent years, autologous platelet-rich plasma (PRP) has been proven to promote wound and soft tissue healing and collagen regeneration. To investigate whether the combination of PRP and ultra-pulsed fractional CO2 laser had...

BACKGROUND Laser treatment may serve as an alternative or adjunctive treatment to conventional mechanical therapy in periodontics. The neodymium-doped:yttrium, aluminum, and garnet (Nd:YAG) laser has been used in periodontics. Systematic reviews aid in clinical decision-making. The aim of this study was to evaluate, in a systematic manner and after a comprehensive search of the literature, the ...

Laser is a powerful tool in many applications. It is especially useful in material processing. Thanks to it's narrow frequency bandwidth, coherence and high power density this instrument is used in many scientific research works and experiments. Often the light beam is intense enough to vaporize the hardest and most heat resistant materials. Besides, due to its high precision, reliability and s...

Recent published studies evaluating the long-pulsed 1064 nm Nd:YAG laser for superficial cutaneous vascular lesions have limited subjects and optimal treatment parameters have not been established. To determine the efficacy and safety of the long-pulsed 1064 nm Nd:YAG laser on superficial cutaneus vascular lesions and analyse retrospectively our experience of a 3-year period are the aims of thi...

Thin films of bioactive glass-ceramic have been deposited on titanium substrates by the Pulsed Laser Deposition (PLD) technique under different experimental conditions. The effect of parameters such as deposition pressure and temperature of heat treatments was studied. The microstructure and the crystalline phases of the coatings were characterized using SEM, EDX and XRD analysis; the phases pr...

We experimentally characterize the ionic emission, including individual charge states Snz+ (z=1, …, 8), from laser-produced tin plasma as a function of intensity employed ns-pulsed laser. The is generated in vacuum microdroplets (diameter ranging 17 to 35 μm) using pulsed Nd:YAG laser light (laser wavelength λ=1.064 over range intensities (0.4–40×1010 W/cm2). measure charge-state-resolved and i...

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...
