BACKGROUND The long-pulsed 1064-nm Nd:YAG laser (employing varying spot sizes, pulse widths, and fluences) has gained popularity for treating lower extremity blue and red vessels that are less than 4 mm in diameter. OBJECTIVE To evaluate the efficacy of high-power 50-ms 1064 Nd:YAG laser in the treatment of class I-III lower extremity vessels. METHODS Ten female patients (mean age of 39 yea...

a hypertrophic scar is defined as an excess healing response that is a dilemma for physicians. several therapies are available: intralesional corticosteroids, topical treatments, cryotherapy, surgery, radiation, silicone gel dressing and laser therapy.pulsed-dye, nd-yag and co2 lasers have been used for treatment of keloids and hypertrophic scars but recurrence is common. recently low-level las...

Title of Document: STUDIES OF SPECTRAL MODIFICATION IN INTENSE LASER PULSE-PLASMA INTERACTIONS Wenxi Zhu, Doctor of Philosophy, 2013 Directed By: Professor Thomas M. Antonsen Jr., Physics Laser pulses propagating through plasma undergo spectral broadening through local energy exchange with driven plasma waves. During propagation, a high power laser pulse drives large amplitude plasma waves, dep...

AIM To examine the effect of carbon dioxide laser irradiation on mineralization in dental pulp cells. METHODOLOGY Rat dental pulp cells were irradiated with a carbon dioxide laser at 2 W output power for 20, 40 and 60 s, and were cultured in ascorbic acid and beta-glycerophosphate containing media. Cell viability was examined 24 h after laser irradiation by a modified MTT assay. Alizarin Red ...

A novel scheme of transferring cold atoms in a double magneto-optical trap (MOT) system has been experimentally demonstrated. Cold cesium atoms trapped in a vapor-cell MOT are efficiently transferred to an ultrahigh-vacuum (UHV) MOT by a continuous-wave divergent Gaussian transfer laser beam. When large red detuning and moderate intensity are adopted for the transfer laser beam, enhancement of ...

BACKGROUND This study investigated the efficacy of low level laser therapy (LLLT) for managing alveolar osteitis (AO). MATERIAL AND METHODS Sixty patients with alveolar osteitis of mandibular third molars were randomly divided into three groups. In group 1, socket irrigation was followed by alvogyl placement, and the treatment was repeated 48 hours later. In group 2, socket was irradiated wit...

OBJECTIVE The purpose of this study was to investigate the effects of low power red laser associated with acidulated phosphate fluoride on the development of induced-dental caries in rats. DESIGN Dental caries were induced in molars of 40 rats divided into five groups: control group (CG), the teeth were not submitted to any treatment; laser group (LG), teeth were irradiated with a low power r...

Low-level laser irradiation of visible light had been introduced as a medical treatment already more than 40 years ago, but its medical application still remains controversial. Laser stimulation of acupuncture points has also been introduced, and mast-cells degranulation has been suggested. Activation of TRPV ion channels may be involved in the degranulation. Here, we investigated whether TRPV1...
