Detection and Diagnosis of Xylella fastidiosa by Specific Monoclonal Antibodies

María Teresa Gorris, Antonio Sanz, Javier Peñalver, María M. López, Mario Colomer, Ester Marco-Noales
2020 Agronomy  
Monoclonal antibodies (MAb) specific to Xylella fastidiosa were obtained through hybridoma technology using heat-treated somatic O antigens from LMG 17159strain. Ten stable hybrydoma clones secreting MAb were selected and their isotype was determined. The MAbs 2G1/PPD, IgG1 showed specificity for X. fastidiosa, detecting all the analyzed strains representing different subspecies, STs and hosts. Polyclonal antibodies (PAb) against X. fastidiosa were also produced and antiserum 17159-O/IVIA was

MAb 2G1/PPD was tested against strain IVIA 5235 in PBS and in spiked raw extract samples from almond, olive, citrus, and other hosts and its sensitivity by DAS-ELISA was 104 CFU mL−1. The MAb also reacted with high affinity and avidity against X. fastidiosa by DASI-ELISA and Tissue print-ELISA. The diagnostic parameters of DAS-ELISA based on MAb were calculated and compared with the gold standard real-time PCR. The diagnostic specificity of MAb2G1/PPD was 100%, the diagnostic sensitivity was 88.5% compared to Harper's real-time PCR and 89.9% compared to Francis' real-time PCR. The agreement between the techniques was almost perfect according to the estimated Cohen's kappa-index, even in symptomless almond trees. The developed immunological techniques represent sustainable and low-cost analysis tools, based on specific, homogeneous, and well-characterized MAbs, which can be obtained in unlimited quantities in a reproducible way and constitute a guarantee for the standardization of commercial kits. They are a valuable option within a polyphasic strategy for the detection of X. fastidiosa.

Testbed for Assessing the Accuracy of Interventional Radiology Simulations [chapter]

Mario Sanz-Lopez, Jeremie Dequidt, Erwan Kerrien, Christian Duriez, Marie-Odile Berger, Stephane Cotin
2014 Lecture Notes in Computer Science  
The design of virtual reality simulators, and more specifically those dedicated to surgery training, implies to take into account numerous constraints so that simulators look realistic to trainees and train proper skills for surgical procedures. Among those constraints, the accuracy of the biophysical models remains a very hot topic since parameter estimation and experimental validation often rely on invasive protocols that are obviously not suited for living beings. In the context of

The simulation of these procedures require complex interaction models between the tools and the blood vessels for which there is no ground truth data available for parametrization and validation. This paper introduces an experimental testbed to address this issue: acquisition devices as well as a data-processing algorithms are used to record the motion of interventional radiology tools in a silicon phantom representing a vascular network. Accuracy and high acquisition rates are the key features of this testbed as it enables to capture dynamic friction of non-smooth dynamics and because it could provide extensive data to improve the accuracy of the mechanical model of the tools and the interaction model between the tools and the blood vessel.

Web-Based Toolkit for Performance Simulation and Analysis of Power Line Communication Networks

Mario Sanz, José Ignacio Moreno, Gregorio López, Javier Matanza, Julio Berrocal
2021 Energies  
AMIs (Advanced Metering Infrastructures) present an important role in Smart City environments, especially from the point of view of distribution and customers, offering control and monitoring capabilities. The use of PLC (Power Line Communication) technology offers a wide range of advantages in AMI, including not needing to deploy an additional communication infrastructure. However, the electrical network was not initially designed for communications, as these networks pose problems depending

For this reason, the use of simulators is proposed to facilitate the deployments based on PLC networks, and analysis and diagnosis tools for the identification of problems in operating networks are also required. This paper presents a toolkit for evaluating and analyzing the performance of PLC networks. This toolkit is composed of SimPRIME, a simulator for the evaluation of NB-PLC PRIME (PoweR line Intelligent Metering Evolution) networks' performance; SimBPL, a simulator for the evaluation of MV-BPL (Broadband Power Line over Medium Voltage) cells' performance; and PRIME Analytics, a forensics tool that allows diagnosis of communication problems in PRIME operational networks based on traffic traces. The toolkit has been developed throughout several research projects in close collaboration with DSOs (Distribution System Operators) and equipment manufacturers, so they provide solutions to actual problems of these industry key players and have been adapted to facilitate their use. As a result, the tools are accessible through web applications to increase their usability, portability, and scalability. These applications represent the first steps in offering PLC simulation and analysis as a service that could benefit the research community, academia, and industry.

Unexpected Propagation of Ultra-Lean Hydrogen Flames in Narrow Gaps

Fernando Veiga-López, Mike Kuznetsov, Daniel Martínez-Ruiz, Eduardo Fernández-Tarrazo, Joachim Grune, Mario Sánchez-Sanz
2020 Physical Review Letters  
Very lean hydrogen flames were thought to quench in narrow confined geometries. We show for the first time how flames with very low fuel concentration undergo an unprecedented propagation in narrow gaps: H_{2}-air flames can survive very adverse conditions by breaking the reaction front into isolated flame cells that travel steadily in straight lines or split to perform a fractal-like propagation that resembles the pathway of starving fungi or bacteria. The combined effect of hydrogen mass

2011 Cardiology Research and Practice  
Although ischemic cardiomyopathy is commonly caused by chronic obstructive coronary disease, the mechanism of the cause is still under investigation. We present echocardiographic strain, magnetic resonance, and histology findings in a chronic ischemia model in preclinical study. This case illustrates the features of multimodality imaging in chronic obstructive coronary disease and gives us great insight into understanding the mechanism of ischemic cardiomyopathy.

AbstractThis study compares upper cervical spine range of motion (ROM) in the three cardinal planes before and after occiput-atlas (C0–C1) stabilization. After the dissection of the superficial structures to the alar ligament and the fixation of C2, ten cryopreserved upper cervical columns were manually mobilized in the three cardinal planes of movement without and with a screw stabilization of C0–C1. Upper cervical ROM and mobilization force were measured using the Vicon motion capture system

With stabilization, the ROM was 11.5° ± 4.3° and 6.6° ± 3.5°, respectively. The ROM without C0–C1 stabilization was 4.7° ± 2.3° in right lateral flexion and 5.6° ± 3.2° in left lateral flexion. With stabilization, the ROM was 2.3° ± 1.4° and 2.3° ± 1.2°, respectively. The ROM without C0–C1 stabilization was 33.9° ± 6.7° in right rotation and 28.0° ± 6.9° in left rotation. With stabilization, the ROM was 28.5° ± 7.0° and 23.7° ± 8.5° respectively. Stabilization of C0–C1 reduced the upper cervical ROM by 46.9% in the sagittal plane, 55.3% in the frontal plane, and 15.6% in the transverse plane. Also, the resistance to movement during upper cervical mobilization increased following C0–C1 stabilization.

2016 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)  
Haptic rendering of soft bodies is essential in medical simulations of procedures such as surgery or palpation. The most commonly used approach is to recreate the sense of touch using a specific design and control of a robotic arm. In this paper, we propose a new approach, based on softrobotics technology. We create a tangible deformable device that allows users to "touch" soft tissues and perceive mechanical material properties, in a realistic manner. The device is able to dynamically provide

We introduce a control algorithm, based on inverse Finite Element Analysis, which controls the actuators in order to recreate a desired stiffness that corresponds to the contact with soft tissues in the virtual environment. The approach uses antagonistic actuation principle to create a wide range of stiffness. We validate our algorithm and demonstrate the method using prototypes based on simple mechanisms.

Se realizó análisis descriptivo, inferencial y de correlación con el paquete estadístico SPSS v.20.Resultados: La edad media de la muestra fue de 71,86 (dt8,93) años, el 52,4% eran hombres. El nivel medio de autocuidados fue de 1,14 (dt0,35) siendo la dimensión más afectada el uso de medicamentos con una autonomía completa del 61,9% y 17,28 (dt7,75) para la calidad de vida siendo la dimensión más afectada el disconfort corporal (m=35,03; dt19,61). Se observó correlación baja entre los síntomas no motores y la calidad de vida (r=0,246;p=0,022), pero no entre los síntomas no motores y el autocuidado (r=0,010;p=0,662).Conclusiones: El nivel de autocuidados y calidad de vida de la muestra estudiada es adecuado. Las dimensiones de calidad de vida más afectadas son el disconfort corporal seguida por el deterioro cognitivo y los síntomas no motores están relacionados con el nivel de calidad de vida. Es relevante considerar estos aspectos en el desarrollo de intervenciones de educación terapéutica dirigidas a pacientes con Parkinson. Objectives: To determine the level of self-care and quality of life in a sample of patients in the early stages of Parkinson's disease and identify the most highly affected dimensions of self-care and quality of life. To study the relationship between non-motor symptoms and these outcome measures.Method: A cross-sectional study was conducted in a sample of 21 patients with stage I or II Parkinson's disease as defined by the Hoenh Yarh Scale. We studied the level of self-care, quality of life, non-motor symptoms and perceived health status. Descriptive, inferential and correlation analyses were performed using SPSS v.20.Results: Mean sample age was 71.86 (SD8.93) years old, and 52.4% were males. The mean score for self-care was 1.14 (SD0.35), and the most highly affected dimension was medication use, with 61.9% of the sample presenting complete autonomy, while for quality of life it was 17.28 (SD7.75), and the most highly affected dimension was bodily discomfort (m=35.03; SD19.61). We observed a correlation between non-motor symptoms and quality of life (r=0.246; p=0.022), but not between non-motor symptoms and self-care (r=0.010; p=0.662).Conclusions: Our sample presented an acceptable level of self-care and quality of life. The most highly affected quality of life dimensions were bodily discomfort followed by cognitive impairment, and non-motor symptoms were related to the level of quality of life. It is important to consider these aspects when designing therapeutic education interventions targeting patients with Parkinson's disease.
