Estimación monocular y eficiente de la pose usando modelos 3D complejos

Trabajo presentado a las XXXV Jornadas de Automática celebradas en Valencia del 3 al 5 de septiembre de 2014.-- Premio Infaimon a mejor artículo de visión.El siguiente documento presenta un método robusto y eficiente para estimar la pose de una cámara. El método propuesto asume el conocimiento previo de un modelo 3D del entorno, y compara una nueva imagen de entrada únicamente con un conjunto pequeño de imágenes similares seleccionadas previamente por un algoritmo de >Bag of Visual Words>. De esta forma se evita el alto coste computacional de calcular la correspondencia de los puntos 2D de la imagen de entrada contra todos los puntos 3D de un modelo complejo, que en nuestro caso contiene más de 100,000 puntos. La estimación de la pose se lleva a cabo a partir de estas correspondencias 2D-3D utilizando un novedoso algoritmo de PnP que realiza la eliminación de valores atípicos (outliers) sin necesidad de utilizar RANSAC, y que es entre 10 y 100 veces más rápido que los métodos que lo utilizan.Este trabajo ha estado financiado en parte por los proyectos RobTaskCoop DPI2010-17112, ERA-Net Chistera ViSen PCIN-2013-047, y por el proyecto EU ARCAS FP7-ICT-2011-287617.Peer Reviewe

Comparative histology of the human and teleost fish thymus / Histologia Comparativa de timo de humanos e peixes teleósteos

Thymus is considered a key component of the vertebrates’ immune system. It is an organ that is only found in these animals whose development may be accompanied through the evolutionary scale, being considered as a facilitator and regulator in the interaction of lymphoid cells and lymphoid organs. In this study not only a morphological but also functional homology were demonstrated, in that it affects the immune system, of the humans and teleost fish thymus. The material of study was composed of the thymus tissue samples of humans who were donated by the Department of Pathology of Hospital Parmenio Piñero, Buenos Aires Argentina belonging to two patients with ages between 6 and 8 years, as well as specimens of fish from different origins. The thymic tissue samples were submitted to histological analysis, immunohistochemistry and transmission electron microscopy. Through the data shown here it is possible to consider that, both in fish as in humans, there are two tracks in the modulation of the immune response, an afferent pathway that begins with the presentation of the antigen and an efferent pathway through which  the result of the lymphocytes, antibodies stimulation  or other effector mechanisms are canalized. In these two phases both in humans and in fish, a mixed population of lymphocytes, the differentiation of lymphocytes in the thymus and the T4 lymphocytes production, play a fundamental role in the success of the immune response. Keywords:

Occurrence of two abdominal neurofibromas in a specimen of Betta splendens

In this work we describe two neurofibromas in Betta splendens studied with optical microscopy, immunohistochemistry and electron microscopy. The specimen studied, that belonged to a private breeder, had marked abdominal distension, and was transferred for diagnosis to the Laboratory of Immunology and Pathology of Aquatic Organisms of the Universidade Federal do Rio Grande – FURG. It was diagnosed as neurofibroma, positive for the antibody to protein S-100. With electronic microscopy, it showed signs of degeneration in some cells and contained mast cells (MC) regularly distributed in the neoplasm mass. With immunohistochemistry we confirmed the histogenesis of the neoplasm, in which there were two neurofibromas, and with electron microscopy we confirmed that the granular cells within the neoplastic tissue were MCs.En este trabajo describimos dos neurofibromas en Betta splendens estudiados con microscopía óptica, inmunohistoquímica y microscopía electrónica. El espécimen estudiado, que pertenecía a un criador privado, presentaba marcada distensión abdominal, fue trasladado para diagnóstico al Laboratorio de Inmunología y Patología de Organismos Acuáticos de la Universidade Federal do Rio Grande – FURG. Fue diagnosticado como neurofibroma, positivo para el anticuerpo contra proteína S-100. Con microscopia electrónica, mostraba signos de degeneración en algunas células y contenía mastocitos distribuidos regularmente en la masa neoplásica. Con inmunohistoquímica confirmamos la histogénesis de la neoplasia, en la que existen dos neurofibromas, y con microscopía electrónica confirmamos que las células granulares que se encuentran entre el tejido neoplásico son MC

Efficient monocular pose estimation for complex 3D models

Trabajo presentado al ICRA celebrado en Seattle (US) del 26 al 30 de mayo de 2015.We propose a robust and efficient method to estimate the pose of a camera with respect to complex 3D textured models of the environment that can potentially contain more than 100, 000 points. To tackle this problem we follow a top down approach where we combine high-level deep network classifiers with low level geometric approaches to come up with a solution that is fast, robust and accurate. Given an input image, we initially use a pre-trained deep network to compute a rough estimation of the camera pose. This initial estimate constrains the number of 3D model points that can be seen from the camera viewpoint. We then establish 3D-to-2D correspondences between these potentially visible points of the model and the 2D detected image features. Accurate pose estimation is finally obtained from the 2D-to-3D correspondences using a novel PnP algorithm that rejects outliers without the need to use a RANSAC strategy, and which is between 10 and 100 times faster than other methods that use it. Two real experimentsdealing with very large and complex 3D models demonstrate the effectiveness of the approach.This work has been partially funded by the Spanish Ministry of Economy and Competitiveness under projects ERANet Chistera project ViSen PCIN-2013-047, PAU+ DPI2011-27510 and ROBOT-INT-COOP DPI2013-42458-P, and by the EU project ARCAS FP7-ICT-2011-28761.Peer Reviewe

Presencia de proteína amiloide en la almeja amarilla Amarilladesma mactroides (Reeve, 1854), una especie emergente para la acuicultura

Amyloid proteins are proteic groups that comprise a superfamily of apolipoproteins, highly conserved in vertebrates, being involved in the modulation of numerous immune responses during infections, injuries or stress. In this study, the yellow clam Amarilladesma mactroides was used as an invertebrate model in the search for amyloid protein deposits in their tissues. Adult specimens of this bivalve were collected from the beach and transported to the Laboratory of Immunology and Pathology of Aquatic Organisms - LIPOA at the Federal University of Rio Grande – FURG. Their tissues were sectioned and stained either with Hematoxylin and Eosin, and examined using light microscopy, or with Congo Red and analyzed under polarized light microscopy. Congo Red stain revealed the presence of amyloid proteins in the foot and digestive glands of the yellow clam. The techniques used proved to be appropriate for this species and evidenced a complementary role of amyloid proteins in the immune response, indicating that they are useful as a marker for the innate immune system and health of invertebrates. The ability to assess the immunological condition can provide information related to the cultivation of emerging species for aquaculture.Las proteínas amiloides son grupos proteicos que comprenden una superfamilia de apolipoproteínas altamente conservadas en vertebrados, estando implicadas en la modulación de numerosas respuestas inmunes durante infecciones, lesiones o estrés. En este estudio, la almeja amarilla Amarilladesma mactroides se utilizó como modelo para invertebrados y demostrar depósitos de proteína amiloide en sus tejidos. Se recolectaron de la playa ejemplares adultos de este bivalvo y se transportaron al Laboratorio de Inmunología y Patología de Organismos Acuáticos (LIPOA) de la Universidad Federal de Rio Grande (FURG). Sus tejidos se procesaron para su estudio histológico y se tiñeron con hematoxilina y eosina, y Rojo Congo. Las secciones histológicas teñidas con hematoxilina y eosina se examinaron con microscopía óptica clásica. Además, las secciones fueron teñidas con Rojo Congo y se analizaron con microscopía de luz polarizada. La tinción con Rojo Congo reveló la presencia de proteínas amiloides en el pie muscular y en las glándulas digestivas de la almeja amarilla. Las técnicas utilizadas demostraron ser adecuadas para la determinación de proteína amiloide en esta especie y evidenciaron un papel complementario de las proteínas amiloides en la respuesta inmune, indicando que pueden servir como marcador del sistema inmunológico innato y la salud de los invertebrados. La capacidad de evaluar la condición inmunológica puede proporcionar información relacionada con el cultivo de especies emergentes para la acuicultura

Effect of Physiotherapeutic Interventions on Biomarkers of Neuropathic Pain: A Systematic Review of Preclinical Literature.

The purpose of this systematic review was to evaluate the effects of physiotherapeutic interventions on biomarkers of neuropathic pain in preclinical models of peripheral neuropathic pain (PNP). The search was performed in Pubmed, Web of Science, EMBASE, Cochrane, Cinhal, Psycinfo, Scopus, Medline, and Science Direct. Studies evaluating any type of physiotherapy intervention for PNP (systemic or traumatic) were included. Eighty-one articles were included in this review. The most common PNP model was chronic constriction injury, and the most frequently studied biomarkers were related to neuro-immune processes. Exercise therapy and Electro-acupuncture were the 2 most frequently studied physiotherapy interventions while acupuncture and joint mobilization were less frequently examined. Most physiotherapeutic interventions modulated the expression of biomarkers related to neuropathic pain. Whereas the results seem promising; they have to be considered with caution due to the high risk of bias of included studies and high heterogeneity of the type and anatomical localization of biomarkers reported. The review protocol is registered on PROSPERO (CRD42019142878). Perspective This article presents the current evidence about physiotherapeutic interventions on biomarkers of neuropathic pain in preclinical models of peripheral neuropathic pain. Existing findings are reviewed, and relevant data are provided on the effectiveness of each physiotherapeutic modality, as well as its certainty of evidence and clinical applicability.post-print761 K

General Characteristics and Risk Factors of Cardiovascular Disease among Interstate Bus Drivers

Workers in the transportation industry are at greater risk of an incorrect diet and sedentary behavior. The aim of our study was to characterize a population of professional bus drivers with regard to clinical and demographic variables, lipid profile, and the presence of cardiovascular risk factors. Data from 659 interstate bus drivers collected retrospectively, including anthropometric characteristics, systolic and diastolic blood pressure, lipid profile, fasting blood glucose, meatoscopy, and audiometry. All participants were male, with a mean age of 41.7 ± 6.9 years, weight of 81.4 ± 3.3 kg, and BMI 27.2 ± 3.3 Kg/m2; the mean abdominal and neck circumferences were 94.4 ± 8.6 cm and 38.9 ± 2.2  cm; 38.2% of the sample was considered hypertensive; mean HDL cholesterol was 47.9 ± 9.5 mg/dL, mean triglyceride level was 146.3 ± 87.9 mg/dL, and fasting glucose was above 100 mg/dL in 249 subjects (39.1%). Drivers exhibited reduced audiometric hearing at 4–8 kHz, being all sensorineural hearing loss. The clinical characterization of a young male population of interstate bus drivers revealed a high frequency of cardiovascular risk factors, as obesity, hypertension, hyperlipidemia, and hyperglycemia, as well as contributing functional characteristics, such as a low-intensity activity, sedentary behavior, long duration in a sitting position, and high-calorie diet, which lead to excessive weight gain and associated comorbidities
