In vitro evaluation of microleakage under orthodontic brackets using two different laser etching, self etching and acid etching methods
This study evaluated the microleakage of brackets bonded by four different enamel etching techniques. Forty freshly extracted
human premolars were divided randomly into four equal groups and received the following treatment: group 1, acid etching;
group 2, self-etching primer (SEP); group 3, erbium:yttrium–aluminum–garnet (Er:YAG) laser etching; and group 4, erbium, chromium:yttrium–scandium–gallium–garnet
(Er,Cr:YSGG) laser etching. After photopolymerization, the teeth were kept in distilled water for 1 month and then subjected
to 500 thermal cycles. Then, the specimens were sealed with nail varnish, stained with 0.5% basic fuchsin for 24 h, sectioned,
and examined under a stereomicroscope. In addition, they were scored for marginal microleakage at the adhesive–......

Development, Characterization, and Application of a Versatile Single Particle Detection Apparatus for Time-Integrated and Time-Resolved Fluorescence Measurements—Part I: Theoretical Considerations
Recent progress in aerosol science has resulted in more challenging demands in the design of new particle beam introduction systems. In this paper, the concept of a variable orifice aerodynamic lens system is presented and supported by the numerical simulation results. This novel particle beam inlet can serve as either a narrow band pass filter (a particle segregator) that only confines particles with a specific size or a broad band pass filter (a particle concentrator) that allows particles with a wide size range to be concentrated on the beam axis. Following a brief description of the inlet system, computational details are described. Simulation of this inlet has been carried out by the commercial computational fluid dynamics protocol FLUENT. Focusing performance and characteristic of si......

Development, Characterization, and Application of a Versatile Single Particle Detection Apparatus for Time-Integrated and Time-Resolved Fluorescence Measurements—Part II: Experimental Evaluation
This paper describes the experimental realization and characterization of a versatile single particle detection apparatus. The system utilizes a novel particle beam inlet that can serve as either an on-line particle concentrator (i.e., all diameters confined in a narrow beam) or as a segregator (i.e., selected diameters confined in a narrow beam) and can be operated in a high-speed mode as well as in a low-speed mode, thus allowing different interaction times between the particles and the laser beam. An aerodynamic sizing technique has been incorporated into the system to provide rapid, real-time, and high-resolution sizing. Parameters such as transmission efficiency and size-segregation efficiency have been measured. The performance of the instrument has been demonstrated by on-line detec......

Skin fluorescence controlled photodynamic photorejuvenation (wrinkle reduction)
In this study the clinical outcome and side effects using the 0.5% 5-ALA in Caucasian skin are investigated and compared to earlier reported non-ablative treatments for wrinkles and improvements of skin texture using 20% ALA photodynamic photorejuvenation.37 healthy Caucasian female patients participated in a randomized, prospective split face study. Two different intense pulsed light (IPL) treatment modalities were investigated; both employed a pre-treatment of approximately one hour of spraying with 0.5% liposome encapsulated 5-ALA. One modality combined type I photorejuvenation with wrinkle reduction (C-PDT) using a waveband from 530 to 750 nm and short pulse durations (7 J/cm2, 2 × 2.5 ms, delay 10 ms). The other modality (PDT alone) emitted a band of wavelengths from 400 to 720 nm, t......

Low-level laser therapy attenuates creatine kinase levels and apoptosis during forced swimming in rats
Abstract Studies suggest that high-intensity physical exercise can cause damage to skeletal muscles, resulting in muscle soreness,
fatigue, inflammatory processes and cell apoptosis. The aim of this study was to investigate the effects of low-level laser
therapy (LLLT) on a decrease in creatine kinase (CK) levels and cell apoptosis. Twenty male Wistar rats were randomly divided
into two equal groups: group 1 (control), resistance swimming; group 2 (LLLT), resistance swimming with LLLT. They were subjected
to a single application of indium gallium aluminum phosphide (InGaAlP) laser immediately following the exercise for 40 s at
an output power of 100 mW, wavelength 660 nm and 133.3 J/cm2. The groups were subdivided according to sample collection time: 24&......
