Murine femur micro-computed tomography and biomechanical datasets for an ovariectomy-induced osteoporosis model

The development of new effective and safer therapies for osteoporosis, in addition to improved diagnostic and prevention strategies, represents a serious need in the scientific community. Micro-CT image-based analyses in association with biomechanical testing have become pivotal tools in identifying osteoporosis in animal models by assessment of bone microarchitecture and resistance, as well as bone strength. Here, we describe a dataset of micro-CT scans and reconstructions of 15 whole femurs and biomechanical tests on contralateral femurs from C57BL/6JOlaHsd ovariectomized (OVX), resembling human post-menopausal osteoporosis, and sham operated (sham) female mice. Data provided for each mouse include: the acquisition images (.tiff), the reconstructed images (.bmp) and an.xls file containing the maximum attenuations for each reconstructed image. Biomechanical data include an.xls file with the recorded load-displacement, a movie with the filmed test and an.xls file collecting all biomechanical results.This study was funded by Basque Country government under the ELKARTEK program No. kk-2018/00031/BC and No. kk-2019/00093/BC

Desarrollo y análisis del sistema distribuido Melissa basado en Klepsydra y ZeroMQ

The objective of this work has been to implement a distributed system with nodes that send images and navigation coordinates over the network. To achieve a proper design in this type of systems, initially solutions to concurrency problems have been introduced, and subsequently analyzed the ZeroMQ, Klepsydra and some alternatives frameworks. The purpose of this research has been to have the appropriate components to create an autonomous embedded system with publisher-subscriber pattern. The purpose of the development has been to evaluate the system executions in different scenarios to obtain the configuration that offers the best performance. In this regard we can conclude that, although a higher frequency of messages (essential for agile response systems) means a slight increase in processing, no event is lost and the memory consumed by the system remains constant.El objetivo de este trabajo ha sido implementar un sistema distribuido con nodos que envíen por red imágenes y coordenadas de navegación.

El propósito de esta investigación ha sido poder disponer de los componentes adecuados para crear un sistema embebido autónomo con patrón publisher-subscriber. La finalidad del desarrollo ha consistido en evaluar las ejecuciones del sistema en distintos escenarios para obtener la configuración que mejor rendimiento ofrezca. A este respecto podemos concluir que, aunque una mayor frecuencia de mensajes (esencial para sistemas de respuesta ágil) supone un ligero incremento de procesamiento, ningún evento se pierde y la memoria que consume el sistema permanece constante
