INTRODUCTION CO2 (Carbon Dioxide) laser application in circumcision, for cutting and coagulation, has been reported to have excellent results. Also, tissue glue has been reported to have advantages over sutures for approximation of wound edges. Most previous studies focused on comparisons between CO2 laser and scalpel, or between tissue glue and sutures. This study prospectively compared the re...

We report progress in assessing the feasibility of a new satellite-based laser-sounding instrument to measure CO2 concentrations in the lower troposphere from space. INTRODUCTION CO2 measurements from ice cores show that atmospheric CO2 concentrations are higher now than they have been in the past 400,000 years. It is becoming increasingly important to understand the nature and processes of the...

OBJECTIVE We evaluated synergistic efficacy and safety of combined topical application of Botulinum Toxin Type A (BTX-A) with fractional CO2 laser for facial rejuvenation. METHODS Twenty female subjects were included for this split-face comparative study. One side of each subject's cheek was treated with fractional CO2 plus saline solution, and the other side was treated with fractional CO2 l...

OBJECTIVE To evaluate the efficacy and feasibility of thermo-ablative fractional CO2 laser for the treatment of symptoms related to vulvo-vaginal atrophy (VVA) in post-menopausal women. METHODS From April 2013 to December 2013, post-menopausal patients who complained of one or more VVA-related symptoms and who underwent vaginal treatment with fractional CO2 laser were enrolled in the study. A...

The tracer gas ratio method, using CO2 as natural tracer, has been suggested as a pragmatic option to measure emissions from naturally ventilated (NV) barns without the need to directly estimate the ventilation rate. The aim of this research was to assess the performance of a low-cost Non-Dispersive Infra-Red (NDIR) sensor for intensive spatial field monitoring of CO2 concentrations in a NV dai...

Posterior digital neurectomy by the guillotine technique resulted in longer duration of cutaneous desensitization of the heels and less neuroma formation compared with perineural capping, CO2 laser coagulation, or CO2 laser transection techniques. Authors’ address: Marion duPont Scott Equine Medical Center, Virginia-Maryland Regional College of Veterinary Medicine, Virginia Tech, P.O. Box 1938,...

Infrared laser evaporation of single aerosol particles in a vacuum followed by vacuum ultraviolet (VUV) laser ionization and time-of-flight mass spectroscopy of the resulting vapor provides a depth profile of the particle's composition. Analyzing glycerol particles coated with 60-150-nm coatings of oleic acid using either a CO2 laser or a tunable optical parametric oscillator as an evaporation ...

BACKGROUND Transmyocardial laser revascularization (TMR) is an emerging treatment for end-stage coronary artery disease. A variety of lasers are currently available to perform the procedure, although their relative efficacy is unknown. The purpose of this study was to compare changes in myocardial blood flow and function 6 months after TMR with holmium:yttrium-aluminum-garnet (holmium:YAG), car...

A newly developed isotope ratio laser spectrometer for CO2 analyses has been tested during a tracer experiment at the Ketzin pilot site (northern Germany) for CO2 storage. For the experiment, 500 tons of CO2 from a natural CO2 reservoir was injected in supercritical state into the reservoir. The carbon stable isotope value (δ(13)C) of injected CO2 was significantly different from background val...

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...
