INTRODUCTION Patient demand for non-surgical, non-invasive, and no-downtime wrinkle reduction treatment procedures has grown dramatically over the past decade as new treatments and technologies have been introduced. This study was performed in order to evaluate the safety and efficacy of the TriPollar radiofrequency (RF) technology and intended for wrinkle reduction treatment. METHODS Thirty-...
To compensate for image artifacts introduced in approximate cone-beam reconstruction, exact cone-beam reconstruction algorithms are being developed for medical x-ray CT. Although the exact cone-beam approach is theoretically error-free, it is subject to image artifacts due to the discrete nature of numerical implementation. We report a study on image artifacts associated with the Grangeat algor...
S U M M A R Y We perform 2-D finite-difference calculations of mode II rupture along a bimaterial interface governed by slip-weakening friction, with the goal of clarifying rupture properties and the conditions leading to the development of unilateral wrinkle-like pulses. The simulations begin with an imposed bilateral rupture in a limited source region. Rupture properties outside the imposed s...
Background: A special pillow was designed to redistribute mechanical stress during sleeping in order to slow down the formation of facial skin wrinkles. Objective: To investigate whether sleeping on a specially designed pillow reduces facial skin wrinkles. Participants and Methods: A 28-day pilot study was carried out in which fifteen healthy female volunteers aged 23 55 years (mean age 35. 6 ±...
Polymer encapsulation of drugs is conventionally used as a strategy for controlled delivery and enhanced stability. In this work, a novel encapsulation approach is demonstrated, in which the organic molecule clotrimazole is enclosed into wrinkles of defined sizes. Having defined wrinkles at the drug/encapsulant interface, the contact between the encapsulating polymer and the drug can be improve...

Hairless mice (HR/ICR) were irradiated chronically with suberythemal doses of UV-B radiation (ultraviolet radiation in wavelength 290-320 nm) immediately before and after production, with cyanoacrylate r sin, of an artificial temporary groove parallel to the midline, which is an unusual direction for wrinkle formation. Data for UV radiation-exposed skin beibre or after production of an artifici...
