BACKGROUND AND OBJECTIVE Laser thrombolysis is a means for clearing blood clots in occluded arteries. Many researchers have studied the mechanisms of clot ablation, and research clinicians have used the technique to treat myocardial infarction with a number of different laser systems. Specifically, a 1-microsec pulsed dye laser has been used clinically to remove blood clots in coronary arteries...

caused by human papilloma virus(HPV) coming from the papova family. They are a common dermatologic complaint, with an estimated incidence of 10% in children and young adults1. Commonly warts occur at the periungual areas and pose a problem in the management2 . Interferons have been used for the treatment of viral disease, cutaneous tumors, HIV-associated Kaposi’s sarcoma and other inflammatory ...

We have characterised a dye-sensitised nanoporous nanocrystalline titania film used in prototype photoelectrochemical solar cell production. The film was sensitised with two types of ruthenium (II) based dyes for different times, between 0.5 and 24 hours. The penetration and coverage for each type of dye was studied using Confocal Laser Scanning Microscopy (CLSM). Varying laser powers were appl...

Objective: To analyse combinational effect of pulsed dye laser and propranolol on treatment of Superficial Hemangioma (SH). Methods: From June 2016 to June 2017, we collected 110 children with SH enrolled in Linyi No.3 People's Hospital. All patients were divided randomly and evenly into two groups (control group and study group). The patients in control group were treated with pulsed dye laser...

BACKGROUND AND OBJECTIVES Infantile hemangiomas are the most common benign tumor in children. They have 3 phases of development: a proliferative phase, an involuting phase, and involution. Although active treatment is often not required, it is necessary in some cases. Of the possible treatments for hemangiomas, lasers have been shown to be effective in all phases of development. We report our e...

Recent advances on the use of mesoporous and mesostructured materials for electronic and optical applications are reported. The focus is on materials which are processed by block-copolymer templating of silica under weakly acidic conditions and by employing dip- and spin-coating as well as soft lithographic methods to bring them into a well-defined macroscopic shape. Several chemical strategies...

BACKGROUND Nodular amyloidosis is a rare form of primary localized cutaneous amyloidosis which is characterized by single or multiple nodules located on the extremities, trunk, genitalia, or face. OBJECTIVE To determine the clinical and histologic response of nodular amyloidosis to pulsed dye laser treatment. METHODS Biopsy-proven amyloid nodules were treated with a 585-nm pulsed dye laser ...

Several fluoride and oxide Tm and (Tm, Yb) doped crystals such as YLF, GLF, YAG, and YAlO3 were tested for pulsed lasing at the ID2 -+ 3 ~ 4 transition (453 nm blue) at room temperature under two step pumping by a Ti:sapphire and a dye laser. Laser operation was obtained for the fluoride crystals. The input-output curves exhibit a saturation effect of emission with respect to both pump lasers. ...

The purpose of this in vitro study was to evaluate the effect of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser irradiation on intracanal dentin surface by SEM analysis and its interference in the apical seal of filled canals. After endodontic treatment procedures, 34 maxillary human incisors were randomly assigned to 2 groups. In the negative control group (n=17), no additional treatment was...

BACKGROUND AND OBJECTIVES Nonablative dermal remodeling is an evolving technology that has generated great interest among both laser surgeons and patients. Evidence indicates that dermal collagen formation is the key mechanism of action for the nonablative techniques. We studied, with ultrasound, new collagen formation after nonablative laser irradiation. METHODS Ten patients with facial rhyt...
