Efectos de un programa de entrenamiento de fuerza unilateral o bilateral sobre el rendimiento en gestos de fuerza velocidad y la asimetría bilateral …
2015
La capacidad de manifestar fuerza se revela fundamental para el rendimiento en gran cantidad de modalidades deportivas. En el futbol la capacidad de acelerar, decelerar, saltar o cambiar de dirección es un elemento importante para el rendimiento en la acción de juego (Hoff y Helgerund, 2004; Stolen, Chamari, Castagna, Wisloff, 2005; Bangsbo, Mohr, Krustrup,2006). Estas acciones están sustentadas en la manifestación de altos niveles de fuerza y potencia por parte del miembro inferior. Al diseñar un programa de intervención para la mejora de la manifestación de fuerza, la manipulación adecuada de las distintas variables que componen el programa de entrenamiento se revela fundamental para cons…
Bilateral Monopoly: A Contribution by Francesco Ferrara
2009
In this paper, we propose an interpretation of the application of "cost of reproduction" of Francesco Ferrara to the exchange between two agents to highlight its relevance for the theory of bilateral monopoly. In the Teoria delle Mercedi (1863), Ferrara gives a numerical example to explain price determination in the exchange between one buyer and one seller. Here, this example is translated into a mathematical model that reproduces the fundamental issues of the neoclassical debate on the indeterminacy of price in the Cournot model (1938), and anticipates the solutions proposed by Edgeworth (1881) at the end of this debate.
Giant uterus in a patient with Klippel-Trenaunay syndrome. Report of a case
2022
Introduction: Klippel-Trenaunay syndrome is an uncommon congenital disease also called angio-osteodystrophy syndrome for its typical disorders characterized by abnormal growth of the soft tissues and bones and vascular malformations. Case report: In this report, we present a rare case of a 46-year-old nulliparous woman with Klippel-Trenaunay syndrome. She suffered from an abnormal uterine bleeding accompanied by severe anemia with need for multiple blood transfusions. At the time of admission, physical examination revealed port-wine stains and varicose veins on her lower limbs and hypertrophy of left lower extremity. We carried out an open bilateral hysteroannexectomy. Histopathology examin…
The Symmetry and Predictive Factors in Two-Stage Bilateral Hip Replacement Procedures
2021
Background: Approximately 10–25% of total hip replacement patients undergo a bilateral procedure. The purpose of this study was to compare selected parameters associated with the first and second hip arthroplasty in patients undergoing two-stage treatment due to bilateral hip osteoarthritis and establish the predictive factors for the second procedure. Methods: This study compared the data on bilateral total hip replacement surgeries conducted in the period between 2017 and 2021 (42 patients). The following parameters from the first and second procedure were compared: the prosthetic stem, head, and insert cup size
Epidural hematoma after cochlear implantation in a 2.5-year-old boy.
2005
OBJECTIVE Report a case of an epidural hematoma after cochlear implantation in a 2.5-year-old boy, the diagnostic and therapeutical emergency management, as well as the postinterventional course and rehabilitation of the child. STUDY DESIGN Retrospective case review. PATIENT Two and a half-year-old boy, suffering from early onset, profound sensorineural hearing loss had been diagnosed at an age of 1.5 years, which had been more severe on the right side initially, but had progressed to bilateral deafness. INTERVENTION AND COMPLICATION: Cochlear implantation on the left side, followed up by an extensive epidural hematoma, causing intracranial compression with a midline shift of 15 mm to the r…
Vergleich der Wertigkeit von Magnetresonanztomographie und Computertomographie bei Patienten mit Nelson-Syndrom
1992
The hypophyses of 13 patients with Nelson syndrome following bilateral adrenalectomy were examined by MRI and CT. Diffuse enlargement of the hypophysis was demonstrated in 8 patients by CT and in 9 by MRI. Compared with CT, MRI provides better demonstration of tumour development, such as abnormal convexity of the cranial margin of the hypophysis (MRI 4/13, CT 1/13), displacement of the infundibulum (MRI 4/13, CT 0/13) or optic chiasm (MRI 2/13, CT 0/13). MRI also provides diagnostically important differentiation between scar tissue and recurrence of tumour following hypophysectomy (MRI 1/3, CT 0/3) and more accurate demonstration of infiltration of the cavernous sinus (MRI 4/13, CT 2/13). C…
Sentinel node mapping in endometrial cancer: Tips and tricks to improve bilateral detection rate. The sentitricks study, a monocentric experience.
2020
Abstract Objective The objective of the study is to show some small tricks for bilateral sentinel lymph node (SLN) uptake in endometrial cancer. Materials and methods Each step of the sentinel lymph node technique was analyzed. The cervix was exposed through the use of vaginal valves and by Martin pliers stapling of the anterior cervical lip. Fifty mg Indocyanine Green (ICG) powder was diluted with 10 ml of physiological solution. The spinal needle was marked at 15 mm with a steri-strip. After 20 min from the administration, in case of no LNS identification, an additional 1 ml in the non-detected side was administered in the superficial cervical area. All cervical injections were made by a …
Full-parallax 3D display from the hole-filtered depth information
2015
In this paper we introduce an efficient hole-filling algorithm for synthetic generation of microimages that are displayed on an integral imaging monitor. We apply the joint bilateral filter and the median filter to the captured depth map. We introduce in any step of the iterative algorithm with the data from a new Kinect capture. As a result, this algorithm can improve the quality of the depth maps and remove unmeasured depth holes effectively. This refined depth information enables to create a tidy integral image, which can be projected into an integral imaging monitor. In this way the monitor can display 3D images with continuous views, full parallax and abundant 3D reconstructed scene fo…
Visual and optical performance with hybrid multifocal intraocular lenses
2010
During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a…
Kernel Based Symmetry Measure
2005
In this paper we concentrate on a measure of symmetry. Given a transform S, the kernel SK of a pattern is defined as the maximal included symmetric sub-set of this pattern. A first algorithm is outlined to exhibit this kernel. The maximum being taken over all directions, the problem arises to know which center to use. Then the optimal direction triggers the shift problem too. As for the measure we propose to compute a modified difference between respective surfaces of a pattern and its kernel. A series of experiments supports actual algorithm validation.
