Experimental investigations on thermal effects of a long-pulse alexandrite laser on blood vessels and its comparison with pulsed dye and Nd:YAG lasers
Abstract Laser has been widely used in the treatment of vascular skin diseases, such as port wine stain, due to the effect of selective photothermolysis in laser on biological tissue. The 755 nm alexandrite laser was expected to achieve better curative effect than the commonly used 585 or 595 nm pulsed dye laser (PDL) because of its deeper tissue penetration. In this study, the dorsal chamber model and microscopic visualization system were used to observe morphology changes...

Evaluation of the clinical and biochemical efficacy of erbium, chromium:ytrium-scandium-gallium-garnet (ER,CR:YSGG) laser treatment in periodontitis
Abstract The objective of this study was to evaluate the clinical and biochemical efficacy of erbium, chromium:ytrium-scandium-gallium-garnet (Er,Cr:YSGG) laser treatment, in addition to non-surgical periodontal treatment (NSPT), in periodontitis patients. This was a single-centre, split-mouth, randomized, controlled 6-month clinical trial. Twenty-seven patients with moderate to advanced periodontitis were included in the study. The patients were randomly assigned to a debridement...

Deep sedation for laser treatment of cutaneous vascular anomalies in children
Abstract Pulse laser treatment is useful for aesthetic improvement in children with capillary vascular malformation and residual superficial haemangiomas. However, pulse laser treatment is painful, and repeated procedures are usually required to achieve a satisfactory clinical result. Evidence shows that analgesia in children undergoing pulse laser treatment may vary from general anaesthesia to no treatment at all. This report describes our institutional experience with deep...

Attenuation of the inflammatory response and polarization of macrophages by photobiomodulation
Abstract In spinal cord injury (SCI), inflammation is a major mediator of damage and loss of function and is regulated primarily by the bone marrow-derived macrophages (BMDMs). Photobiomodulation (PBM) or low-level light stimulation is known to have anti-inflammatory effects and has previously been used in the treatment of SCI, although its precise cellular mechanisms remain unclear. In the present study, the effect of PBM at 810 nm on classically activated BMDMs was evaluated...

Effect of the usage of Er,Cr:YSGG laser with and without different remineralization agents on the enamel erosion of primary teeth
Abstract The aim of the present study was to evaluate the effects of different remineralization agents associated with erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) (0.5 W power, 20 Hz frequency, 60% water, 40% air, 25 mJ pulse energy, 8.84 J/cm2 fluence, 60 μs pulse duration, 600 μm tip diameter, and an approximate 1–1.5 mm distance to the target) laser irradiation on erosion induced by the consumption of carbonated drinks in human primary enamel. There were...

miR-27b promotes angiogenesis and skin repair in scalded rats through regulating VEGF-C expression
Abstract In this study, the effects of miR-27b on angiogenesis in skin repair procedure in rats with deep II degree scald were explored. The rat model of deep II scald was established. miR-27b mimics and inhibitor were injected daily at the wound site for 3 weeks. The healing of scald was observed at 0, 3, 7, 14, and 21 days after the model was established, and the pathological changes of skin were observed by HE and Masson’s trichrome stains. Skin tissues were taken 14 days...
