Indocyanine Green to Assess Vascularity of Ileal Conduit Anastomosis During Pelvic Exenteration for Recurrent/Persistent Gynecological Cancer: A Pilo…
2021
IntroductionPelvic exenteration performed for recurrent/persistent gynecological malignancies has been associated with urological short- and long-term morbidity due to altered vascularization of tissues for previous radiotherapy. The aims of the present study were to describe the use of intravenous indocyanine green (ICG) to assess vascularity of urinary diversion (UD) after pelvic exenteration for gynecologic cancers, to evaluate the feasibility and safety of this technique, and to assess the postoperative complications.MethodsProspective, observational, single-center, pilot study including consecutive patients undergoing anterior or total pelvic exenteration due to persistent/recurrent gy…
Hyperboloid and Parabolid in Orthogonal Axonometric
2012
This paper presents the issue of a long research on the representation of the complex surface in descriptive geometry. The ability to use the different techniques of representation aims to achieve results that you didn’t image before. In Palermo University, at the Engineering School, the researcher involved the study on the simplify of the so elaborated way to represent the geometry and its applications in architecture buildings and engineering implants. We just report below the application methods to represent two of the most used quadric surfaces in the practice of buildings. We are talking about Hyperboloid and Paraboloid quadric surface represented in axonometric projecting. This method…
Optiskas metodes asinsvadu dzīšanas novērtējumam un monitoringam

Maģistra darba mērķis ir izpētīt artērijas ar ICG/hitozāna plāksteri fluorescences un difūzā refleksijas intensitātes spektrus iedarbības vietās ar lāzera iedarbību un bez. Operācijām uz artērijas piemīt sava sarežģītība tādēļ, ka artērijas diametrs ir mazs, tāpēc aizšūt artērijas griezumu nav tik vienkārši. Tādēļ tika izgudrots hitozāna/ICG plāksteris, ja uz to iedarbojas ar 810 nm lāzeri, notiek plākstera adhēzija ar artēriju. Lai veiktu operāciju, ir jāizvēlas pareizā lāzera iedarbības doza uz plāksteri. Šajā nolūkā tika izpētīti autofluorescences intensitātes spektri, ICG fluorescences intensitātes spektri tuvajā infrasarkanajā diapazonā, un paraugu difūza atstarošana. Rezultātā tika ko…
Comparison between Laparoscopic and Robotic Approach for Sentinel Lymph Node Biopsy in Endometrial Carcinoma Women
2022
Robotic surgery has been approved as an alternative to laparoscopy to improve surgical outcomes. There is neither a consensus nor a systematic assessment of the literature about the superiority of the robotic approach over the laparoscopic one for sentinel lymph node (SLN) biopsy in endometrial carcinoma (EC) women. Therefore, a systematic review and meta-analysis was performed to compare the laparoscopic and robotic approaches for SLN biopsy in EC patients. Five electronic databases were queried from their inception to May 2022 for peer-reviewed studies, comparing such approaches in SLN biopsy in EC patients. The rate of detected SLN, dissected SLN, intraoperative and postoperative complic…
Is spectral domain optical coherence tomography useful in improving the contour line with the heidelberg retina tomograph?
2012
Purpose: To compare the measurements of the optic disc in glaucoma patients and glaucoma suspects with spectral domain optical coherence tomography (SD-OCT) and confocal scanning laser ophthalmoscopy (HRT) before and after adjustment of the contour line with the help of the OCT.Methods: In 109 consecutive patients (109 eyes), optic disc parameters were compared prospectively between the 2 devices before and after adjustment of the optic disc area (ODA) on the HRT3 with ODA obtained with the Cirrus SD-OCT as a reference. Intraclass correlation coefficients (ICC) and the 95% limits of agreement (LoA) with Bland-Altman plots were used to compare the agreement of the pre and post-adjustment mea…
Eficacia de procesamiento de los entrañamientos y de las implicaturas conversacionales generalizadas: la lógica deductiva y la lógica por defecto
2022
This work aims to study the processing differences that occur between deductive logic and default logic. Since the entailments are based on deductive logic and generalised conversational implicatures (GCI) are built from the default logic, two questionnaires were proposed to collect the processing efficiency expressed as the number of hits per minute. The data collected shows that there is a significant difference in the processing of entailments and ICGs: entailments are processed more efficiently than ICGs and, therefore, it is concluded that the default logic requires greater cognitive effort. Este trabajo tiene como objetivo estudiar las diferencias de procesamiento que se producen al a…

Take-off analysis of the Olympic ski jumping competition (HS-106m).
2007
Abstract The take-off phase (approximately 6 m) of the jumps of all athletes participating in the individual HS-106 m hill ski jumping competition at the Torino Olympics was filmed with two high-speed cameras. The high altitude of the Pragelato ski jumping venue (1600 m) and slight tail wind in the final jumping round were expected to affect the results of this competition. The most significant correlation with the length of the jump was found in the in-run velocity ( r =0.628, p n =50). This was a surprise in Olympic level ski jumping, and suggests that good jumpers simply had smaller friction between their skis and the in-run tracks and/or the aerodynamic quality of their in-run position …
Cities, hinterlands and agglomeration shadows: spatial developments in Finland over 1880-2004
2011
This paper analyzes long-term spatial developments in Finland by focusing on two predictions of the new economic geography (NEG) models, the increasing persistence of locational patterns and the emerging agglomeration shadow, i.e. the rising dominance of growth centers. Pre- and post-war periods are distinguished to roughly express the shift from an agriculture-based economy to a post-industrial country. The analyses base on the assumption that each of the 19 Finnish regions has a center of its own and the rest of the region forms its local hinterland. The empirical analysis is based on regional population data from 1880 to 2004 at decade intervals. First, to analyze the persistence of loca…
Sentinel-node biopsy in early stage ovarian cancer: a prospective multicentre study (SELLY)
2019
BackgroundSystematic para-aortic and bilateral pelvic lymphadenectomy is included in the standard comprehensive surgical staging in presumed early epithelial ovarian cancer. No prospective randomized evidence suggests it has potential therapeutic value, and related morbidity is not negligible.Primary Objective(s)To assess sensitivity, safety, and feasibility of the sentinel lymph node technique in identifying the presence of lymph node metastases in patients with early stage epithelial ovarian cancer.Study HypothesisSentinel lymph node detection with indocyanine green can accurately predict nodal status in a cohort of women with early stage epithelial ovarian cancer.Trial DesignThe SELLY tr…
