Introduction. Topical application of local anesthetics is currently considered to be the easiest, most effective, and convenient way for treatment of patients who may be undergoing superficial dermatosurgical procedures. Materials and Methods. This study compares the anesthetic potential of 2.5% lidocaine and 2.5% prilocaine topical cream with 7% lignocaine and 7% tetracaine combination cream f...
Materials and method 110 leiomyomas in 98 women (average age 39,3 years) were treated with MRI-guided focused ultrasound (MRgFUS). The treatment is carried out using the ablative properties of the HIFU system under 3T MRI guide. Symptoms (e.g. menorrhagia, pelvic pain) were scored using Severity Score (SS) and quality of life was determined using the UFS-QOL score. Pre-treatment measurementes o...
Abstract Ablative materials represent a widespread solution for shielding space vehicles from overheating during reentry phase in atmosphere where the high heating fluxes and consequent temperatures cannot be compatible with vehicle structure safety of payload and/or crew. In this work, two different kinds carbon-phenolic ablators density 0.3 g/cm 3 were manufactured their mechanical thermal pr...
Composites with excellent thermomechanical and thermochemical properties are urgently needed in the aerospace field, especially for structural applications under high-temperature conditions. Carbon fiber-reinforced Si-based composites considered most promising potential materials due to their oxidation resistance ablative behaviors, good designability, mechanical properties. The reinforcement o...
