determinants of early onset haze were retrospectively explored in patients who had been undergone laser-assisted sub-epithelial keratectomy (lasek) in a private eye clinic. the technique included creating an epithelial flap following 20 seconds exposure to 20% alcohol. ‘optimized’ ablation profile was used by allegretto laser (wavelight technologie). following repositioning of the flap, a singl...

BACKGROUND The increasing use of injectable fillers has been increasing the occurrence of disfiguring anaerobic infection or granulomas. This study presents two types of laser-assisted evacuation of filler material and inflammatory and necrotic tissue that were used to treat disfiguring facial nodules after different types of gel fillers. MATERIALS AND METHODS Infectious lesions after hydroge...

Introduction In this study, we describe the results of controlled synthesis and application of gold coated Fe3O4/SiO2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (SPR) Phenomena. Materials and Methods Magnetite Nano-Particles (MNPs) were prepared by means of co-precipitat...

background sub-inguinal varicocelectomy is widely used among surgeons. objectives the aim of this study was to evaluate the outcome of varicocelectomy using a modified microsurgical method, specifically a loupe-assisted method, and its effects on sperm parameters in infertile men. patients and methods this study was performed in 40 patients who presented with varicocele. all patients had at lea...

In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...

In the low temperature environment generated by supersonic flow in process of laser assisted retardation condensation isotope separation for BCl<sub>3</sub>, molecular isotopes BCl<sub>3</sub> and carrier gas (rare (RG): He, Ne, Ar, Kr, Xe) can form BCl<sub>3</sub>:RG dimer via contact collision process. The mechanism relationship between concentration absolu...

Positive and negative ions generated by laser-based ionization methods from three gold:thiolate cluster compounds are mass analyzed by time-of-flight mass spectrometry. The three compounds have similar inorganic core masses ( approximately 29 kDa, approximately 145 Au atoms) but different n-alkanethiolate ligands associated with each cluster compound (Au:SR, R = butane, hexane, dodecane). Irrad...

We demonstrate ultrafast incoherent depopulation of a quantum dot from above to below the transparency point using LA-phonon-assisted emission stimulated by a red-shifted laser pulse. The QD is turned from a weakly vibronic system into a strongly vibronic one by laser driving which enables the phonon-assisted relaxation between the excitonic components of two dressed states. The depopulation is...

We show that ultrafast surface science studies using the laser-assisted photoelectric effect can benefit from longer-wavelength infrared dressing beams. We compare soft-x-ray photoemission from a Pt 111 surface dressed by 1300 and 780 nm light. Using 1300 nm light, the amplitude of the laser-assisted photoelectric signal is enhanced sevenfold compared with 780 nm. This allows lower dressing las...
