Paresia do IV par craniano: Avaliação Quantitativa do Outcome Cirúrgico

Introdução: A paresia do IV par craniano (P IV) é a uma das principais causas de diplopia vertical em adultos e crianças. Apesar de alguns casos apresentarem recuperação espontânea, os restantes não são autolimitados e a cirurgia surge como principal arma terapêutica. O objetivo do nosso estudo passou por aplicar um método de avaliação quantitativa do campo visual binocular (CVB) e, assim, definir o outcome cir...

Main Body: This selection of highlights provides commentary on 21different topics selected by each coauthoring Editorial Board member addressinga variety of aspects ranging from novel radiochemistry to first-in-humanapp...

Fully Automated Production of [68Ga]GaFAPI-46 with Gallium-68 from Cyclotron Us...

68Ga-based radiopharmaceuticals are routinely used for PET imaging of multiple types of tumors. Gallium-68 is commonly obtained from 68Ge/68Ga generators, which are limited in the quantity of activity produced. Alternatively, gallium-68 can easily be produced on a cyclotron using liquid targets. In this study, we optimized the GMP production of [68Ga]GaFAPI-46 using gallium-68 produced via a standard medical cy...

Experimental Determination of Excitation Function Curves through the Measuremen...

The present work describes a method to determine excitation function curves and, therefore, cross-sections, making use of the irradiation of liquid targets at distinct energies in a biomedical cyclotron. The method relies on the derivative of experimentally measured thick target yield curves to determine the corresponding excitation function curves. The technique is presented as a valid and practical alternativ...

Education and training in radiation protection in Europe: an analysis from the ...

Background: A Strengths, weaknesses, opportunities and threats analysis was performed to understand the status quo of education and training in radiation protection (RP) and to develop a coordinated European approach to RP training needs based on stakeholder consensus and existing activities in the field. Fourteen team members represented six European professional societies, one European voluntary organisation,...

Is VO2 kinetics influenced by swimming intensity in maximal and supramaximal ve...

Made available in DSpace on 2022-04-28T17:20:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; The aim of the present study was to determine if VO2 Kinetics (VO2K) and specifically, the time constant (tau) from rest to maximal and supramaximal velocities is influenced by the swimming intensity. Thirteen well trained female swimmers performed a discontinuous incremental test for maximal oxygen upt...

Made available in DSpace on 2022-04-28T17:20:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; The aim of this study was to analyse the physiological responses of swimmers while performing different swimming distances at the maximal aerobic velocity (MAV) in order to understand the swimmers physiological impact along different levels of effort. Eight well trained swimmers performed a discontinuou...

Results: This commentary of highlights has resulted in 21 different topics selected by each member of the Editorial Board addressing a variety of aspects ranging from novel radiochemistry to first in man application of ...

Thermal Simulation Studies for the Characterization of a Cyclotron Liquid Targe...

This work presents a simulation model developed with the aim to represent and study the thermal behavior of cyclotron liquid targets. Understanding and improving the thermal behavior of the target system is fundamental to improving the target overall performance, especially when using thick target windows, for which a larger amount of heat generated can be limiting. ANSYS CFX and SRIM software were used to deve...
