A reduced graphene oxide (rGO) film was used as the matrix in the matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF-MS) for the detection of octachlorodibenzo-p-dioxin (OCDD) with a detection weight as low as 500 pg.

Background. Few data are available on the long-term outcome of patients who undergo laser-assisted balloon angioplasty for recanalization of occluded peripheral arteries. Because the cost of laser angioplasty is high, the value of the method should be carefully analyzed before it can be considered a routine method for recanalization. The purpose of this study was to evaluate the early and late ...

Chromophore-assisted laser inactivation of protein function has been achieved. After a protein binds a specific ligand or antibody conjugated with malachite green (C.I. 42,000), it is selectively inactivated by laser irradiation at a wavelength of light absorbed by the dye but not significantly absorbed by cellular components. Ligand-bound proteins in solution and on the surfaces of cells can b...

BACKGROUND Liposuction of the neck is currently one of the most common cosmetic surgical procedures. In the present study, the author describes his experience with neck and jowl laser-assisted liposuction. STUDY DESIGN/MATERIALS AND METHODS In this procedure, submental lipodystrophy is treated with an Nd:YAG laser, at a 1,064 nm wavelength. Over a 5-year-period, 82 subjects were treated using...

There has been tremendous progress in the past decades in the utilization of lasers for treating patients with glaucoma. This article reviews the use of lasers in different areas of glaucoma, including the shift from argon laser trabeculoplasty (ALT) to selective laser trabeculoplasty (SLT), laser trabeculoplasty as an initial treatment for glaucoma, new laser trabeculoplasty procedures under i...

AIM Pulp capping represents the boundary between conservative and endodontic therapy. The importance of this technique, which considerably improves the prognosis of the tooth, justifies the quest for new techniques and technologies: the most recent literature reports more predictable results (approximately 90%) with cappings performed using laser of different wavelengths, compared to traditiona...

BACKGROUND Femtosecond-laser assisted clear cornea cataract surgery may hold promise in safer and more effective procedures. We decided to perform a comparative study to standard manual incision phacoemulsification surgery. METHODS This is a single-center, single-intervention, and prospective comparative data evaluation of 133 consecutive cases subjected to cataract surgery. Group-A (Phaco), ...

PURPOSE To discuss intraoperative and postoperative femtosecond laser-assisted LASIK flap complications and their management. METHODS Review of published literature. RESULTS Flap creation is a critical step in LASIK. The femtosecond laser has improved the overall predictability and safety of the lamellar incision, but complications can still occur during or after flap creation. Although man...
