Background: The Agility multileaf collimator (MLC) mounted in Elekta linear accelerators features some unique design characteristics, such as large leaf thickness, eccentric curvature at the leaf tip, and defocused leaf sides ('tilting'). These characteristics offer several advantages but modeling them in treatment planning systems (TPSs) is challenging.
Purpose: The goals of this study were to investigate the challenges faced when modeling the Agility in two commercial TPSs (Monaco and RayStation) and to explore how the implemented MLC models could be improved in the future.
Languages use predicates and arguments to express events and event participants. In order to establish generalizations concerning the variety languages show regarding the strategies for discerning some arguments from the others, the concept of roles-and, particularly, macroroles, mesoroles, and microroles-associated with participants provides a widely studied starting point. In this article, the formal properties in the arguments of a set of 14 verb meanings in Spanish Sign Language have been analyzed.

Methods: Multicenter study. Epidemiological and clinical data was collected through electronic medical records of all patients with PsA who started UST in 15 hospitals of Spain.
Inhibitors of tumor necrosis factor-alpha (anti-TNF-alpha) are widely used in different medical specialties. The main adverse effect of these agents is the increased risk of infection. We report the case of a 30-year-old man with ankylosing spondylitis who had begun receiving golimumab two weeks earlier.

Nevertheless, the use of continuous perineural infusions allows sustained pain control. Ultrasound-guided interpectoral block followed by the placement of catheters in patients undergoing mastectomies with or without lymph node axillary dissections can result in sufficient pain control.

Methods And Materials: From September 2011 to December 2014, 102 patients were treated with postoperative BT for endometrial carcinoma. Seventy-four patients received a single 7 Gy dose after external beam irradiation (Group 1), and 28 intermediate-risk patients received three daily fractions of 6 Gy (Group 2).
Background: Early excision of burn wounds is the standard approach for burns, but it is usually associated with the need of allogeneic blood transfusion. Our aim was to determine if intravenous administration of tranexamic acid (TXA) was able to reduce packed red blood cell (pRBC) transfusion requirements in burn patients.
Methods: We conducted a retrospective cohort study of 2 consecutive series of severely burned patients (≥20% total body surface are) admitted for primary burn surgery.
Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis characterized by an asymptomatic soft-tissue swelling affecting the skin of the lateral spects of the proximal interphalangeal joints of the fingers, and sometimes can be misdiagnosed with some rheumatic conditions. Magnetic resonance images changes have not been described in any of the case reports in the literature. We report here a case of PDD in a 19-year-old male and we describe its findings on X-ray and magnetic resonance images.
View Article and Find Full Text PDFA new method for on-line batter monitoring using ultrasound techniques is presented. Air or gas incorporation is done during the beating process which produces bubbles in the mixture. The density and the compressibility of the batter vary as a function of mixing time and are quality index of batter.
