BACKGROUND Several laser technologies exist for improving rhytides, pigmentation, and skin texture. Recent advances in technology introduced a new wavelength, 2,790 nm, erbium:yttrium-scandium-galium-garnet (Er:YSGG) for treatment of photoaging. 2,790 nm Er:YSGG has a water absorption coefficient between CO(2) laser and Er:YAG laser and has both ablative and fractional-ablative capabilities. ...

BACKGROUND Combination laser treatments can potentially increase the effectiveness of treatment without the additional downtime associated with another procedure. OBJECTIVE To assess the effectiveness and safety of combining non-ablative fractional treatments with optimized intense pulsed light. METHODS AND MATERIALS Ten subjects (Group A) received full face treatments with a non-ablative f...

New concepts for protective shields for NASA’s Crew Exploration Vehicles (CEVs) and planetary probes offer improved mission safety and affordability. Hazards include radiation from cosmic rays and solar particle events, hypervelocity impacts from orbital debris/micrometeorites, and the extreme heating environment experienced during entry into planetary atmospheres. The traditional approach for ...

Endobronchial ablative therapies are used to address a variety of malignant and benign airway lesions. By utilizing endobronchial ablative techniques patients with symptomatic airway lesions may receive significant symptom improvement, improved quality of life, and improved life expectancy. Endobronchial ablative therapies include laser, electrocautery, argon plasma coagulation, cryotherapy, br...

ABSTRACT: The aim of this paper was to identify, for a specific maneuver, the optimal combination between the trajectory and the associated heat shield configuration, namely the locations and thicknesses of the ablative and reusable zones, that maximize the allowable payload mass for a spacecraft. The analysis is conducted by considering the coupling between the trajectory’s dynamics and the he...

BACKGROUND Fractional photothermolysis, an approach to laser skin resurfacing that creates microscopic thermal wounds in skin separated by islands of spared tissue, was developed to overcome the high incidence of adverse events and prolonged healing times associated with full coverage ablative laser procedures. OBJECTIVE To examine whether fractional nonablative laser resurfacing induces skin...

BACKGROUND There has been growing patient demand for laser technology to treat rhytids and to refine skin texture without the associated lifestyle hindrance common to ablative cutaneous procedures. Nonablative laser systems have been developed to meet this need and, in many instances, have replaced ablative lasers as the preferred treatment modality. OBJECTIVE To review long-pulsed diode lase...

PURPOSE We report the results of pediatric retroperitoneoscopic renal ablative surgeries, which were performed with only three trocars. MATERIALS AND METHODS We retrospectively reviewed the charts of children who underwent laparoscopic urological procedures on the upper urinary tract at our institution between 2006 and 2012. These procedures consisted of nephrectomies, nephroureterectomies an...
