The present work was targeted to design a surface against cell seeding and adhering of bacteria, Bacillus subtilis. A multi-walled carbon nanotube/titanium dioxide nano-power was produced via simple mixing of carbon nanotube and titanium dioxide nanoparticles during the sol-gel process followed by heat treatment. Successfully, quercetin was immobilized on the nanocomposite via physical adsorpti...

The axial dispersion coefficient of hexachlorobenzene in supercritical carbon dioxide is investigated in a fixed-bed packed with glass beads. The on-line chromatographic pulse-response experiment is used in order to study the dynamics of a packed column under supercritical conditions. The radial dispersion is assumed negligible because of the packed column geometry. To estimate the axial disper...

BACKGROUND Pyogenic granuloma is a frequently diagnosed, benign vascular lesion. OBJECTIVES To present the use of the combined continuous-wave/pulsed carbon dioxide (CO2) laser as an innovative therapeutic method, to compare it with established methods, and to assess its results. DESIGN Prospective observational study between March 1998 and July 2000, comprising 1 treatment session with 6-w...

BACKGROUND While skin resurfacing using pulsed carbon dioxide lasers appears to have a skin-tightening effect clinically, the debate continues over its actual effects on dermal collagen. OBJECTIVES To provide quantitative measures of skin elasticity changes associated with pulsed carbon dioxide laser skin resurfacing and to introduce to the facial plastic surgery community the Cutometer SEM 5...

Q-switched output of 1.1 J per pulse at 2-micron wavelength has been achieved in a diode pumped Ho:Tm:LuLF laser using a side-pumped rod configuration in a Master-Oscillator-Power-Amplifier (MOPA) architecture. This is the first time that a 2-micron laser has broken the Joule per pulse barrier for Q-switched operation. The total system efficiency reaches 5% and 6.2% for single and double pulse ...

Reports have been published describing successful in vivo recanalization of atherosclerotic plaque-occluded peripheral and coronary arteries using energy from argon and carbon dioxide laser sources [1-3]. In the case of the argon laser, optical fibers acting as waveguides incorporated in catheters were used. In the case of the carbon dioxide laser, direct lineof-sight application through a need...

BACKGROUND Injection of calcium hydroxylapatite filler may result in nodule formation owing to superficial placement of the filler. Calcium hydroxylapatite nodules are difficult to reverse. Previously reported therapeutic options are limited and include intralesional triamcinolone, massage, needling, and excision, each with inconsistent results or potential for scarring. OBSERVATION We have o...

LFT: liver function test PLCNA: primary localized cutaneous nodular amyloidosis INTRODUCTION Amyloidosis is a group of conditions that involve the deposition of amyloid proteins in various tissues. It is generally classified as either systemic or cutaneous. Primary localized cutaneous nodular amyloidosis (PLCNA) is the rarest form of cutaneous amyloidosis with the amyloid depositing in the derm...
