Focalizing slow neutron beams at and below micron scales and discussion on BNCT (II)

We studied the propagation of slow neutrons and their waveguiding properties in certain suitable thin films where Ti and Si play a key role, having in mind their possible use in Boron Neutron Capture Therapy (BNCT) of small tumors. In PBSi2017 we presented a general overview and some specific proposals for improved focalization of slow neutrons (at and a bit below one micron, with propagation up to about 1 m. with relatively small attenuation), by omitting a good number of quantitative aspects. The present work, based upon our presentation in PBSi2018, extends our previous proposals in PBSi2017 and provides more quantitative descriptions of part of them. Neutron wavelengths versus characteristic dimensions of the waveguides in our proposals typically require quantum-mechanical analysis: specifically, the description of the confined neutrons by means of propagation modes. The confined propagation of incoming waves along waveguides, the evolution of the resulting propagation modes and related issues are investigated. Those features give rise to computational challenges, depending on the smallness of (neutron wavelengths/characteristic dimensions). Approximate analytical formula is provided for the corresponding quantum-mechanical probability. Numerical estimates and the results of some simulations are presented. Consequences of the latter for BNCT will be discussed briefly

A community approach to the Neotropical ticks-hosts interactions

The relationships between ticks and hosts are relevant to capture the ecological background driving the evolution of these parasites. We used a set of 4,764 records of ticks of the genera Amblyomma, Ixodes, and Haemaphysalis and their hosts in the Neotropics to approach the tick-host relationships using a network-based construct. The network identified 9 clusters of interacting hosts and ticks partially connected by 22 tick species that switch their host range according to their life cycle stage. These links among clusters do not confer an extra resilience to the network following removal of hosts and subsequent cascade extinctions of ticks: the robustness of the network slightly changed when these inter-clusters links are considered. Phylogenetic clustering of ticks to hosts at cluster level was not significant (p > 0.15) but if examined individually 63 tick species/stages (59%) displayed such clustering, suggesting that their hosts have a related phylogenetic background. We interpreted these results under an ecological perspective in which ticks could track its environmental niche associating to vertebrates that would maximize tick survival under the range of abiotic traits. We encourage these integrated analyses to capture the patterns of circulation of tick-transmitted pathogens, a topic still unaddressed in the Neotropical region.EEA RafaelaFil: Estrada-Peña, Agustin.

Cuidados de enfermería al paciente con disfonía espasmódica o distonía laríngea

Introducción/justificación: La disfonía espasmódica (DE) es una enfermedad rara que se caracteriza por movimientos espasmódicos de las cuerdas vocales. Se trata de un trastorno de difícil diagnóstico y cuyo tratamiento sólo mejora temporalmente los síntomas. Constituye un proceso complicado en el que se producen repercusiones sobre todo a nivel psicológico y social. En consecuencia, la función de enfermería plantea un papel decisivo en la mejora del afrontamiento, la estabilización emocional y la readaptación con el entorno. El presente Trabajo de Fin de Grado consta de un Plan de Cuidados Enfermero a una paciente recientemente diagnosticada de disfonía espasmódica de larga evolución.Objetivos: Determinar un Plan de Cuidados orientado a proporcionar ayuda y apoyo psicosocial a un paciente de DE, a través del diseño e implantación de un Proceso de Atención de Enfermería, en el área de Atención Primaria.Metodología: Trabajo basado en una revisión bibliográfica en distintas fuentes de información como bases de datos, asociaciones, uso de escalas de valoración, todo ello realizado mediante la metodología científica enfermera. Se realiza un Plan de Cuidados comenzando con una valoración integral siguiendo los Patrones Funcionales de salud de Marjory Gordon, para posteriormente nombrar los diagnósticos enfermeros, objetivos e intervenciones con la taxonomía enfermera NANDA, NOC, NIC.Conclusión:. Tras la realización de las actividades programadas, se podrá conseguir los objetivos planteados en nuestro plan de cuidados, centrándose estos en la formación al paciente y su entorno, el apoyo psicosocial, el afrontamiento de la enfermedad con el fin de recuperar el bienestar del paciente.<br /

Diffusion study in tailored gratings recorded in photopolymer glass with high refractive index species

We report results on the temporal evolution of the diffraction efficiency of volume holographic gratings recorded in a photopolymer glass incorporating Zr-based high refractive index species (HRIS) at molecular level. We record high spatial frequency gratings in this material with diffraction efficiencies near 100%. A two-component diffusion model is introduced for the evolution of refractive index modulation in darkness. Diffusion parameters for the Zr-based HRIS and monomer components have been determined. Codirectional diffusion of both components is demonstrated. The results show the feasibility for tailoring in this photomaterial holographic gratings with high diffraction efficiency over a wide range of spatial frequencies.

Gold nanoparticles coated with carbosilane dendrons in protein sample preparation

The feasibility of using carbosilane dendronized gold nanoparticles (GNPs) for protein sample preparation was evaluated. Three different dendrons with three different generations (1G, 2G, and 3G) were employed to modify the GNPs, viz. sulfonate terminated (STC-GNPs), carboxylate terminated (CTC-GNPs), and trimethylammonium terminated (ATC-GNPs)dendrons. The synthesis of the CTC-GNP is described. The other dendronized GNPs were synthesized using previously described routes. Bovine serum albumin, lysozyme, and myoglobin were employed to study the potential of GNPs to interact with proteins. The interaction between the GNPs and the proteins was evaluated using fluorescence spectroscopy and polyacrylamide gel electrophoresis. The CTC-GNPs and STC-GNPs under acidic and neutral conditions, respectively, promoted the establishment of electrostatic interactions with positively charged proteins. Proteins from 10 to 75kDa molecular weights interacted with GNPs at protein: nanoparticle ratios of 1:0.25. The GNPs were applied to the extraction of proteins from a peach seed. In the authors&apos; perception, the method is a clean alternative to established extraction methods based on the use of organic or polluting chemicals.Ministerio de Economía, Comercio y EmpresaUniversidad de AlcaláCentro de investigación Biomédica en Red.

Towards an Effective, Rational and Sustainable Approach for the Control of Cattle Ticks in the Neotropics

Ticks and transmitted pathogens constitute a major burden for cattle industry in the Neotropics. To address this limitation, the Spanish Ibero-American Program of Science and Technology in Development office (CYTED) supported from 2018 a network of scientists named “LaGar” (CYTED code 118RT0542) aimed at optimizing the control strategies of cattle ticks in the neotropical region. As part of network activities, a meeting and course were organized on 4–8 November 2019 in Querétaro, Mexico to address the objective of developing the infrastructure necessary for an effective, sustainable (i.e., combination of efficacious acaricides with anti-tick vaccines) and rational (i.e., considering tick ecology, seasonal dynamics and cattle-wildlife interactions) control of cattle tick infestations and transmitted pathogens. The course was focused on scientists, students, cattle holders and producers and pharmaceutical/industry representatives. In this way the course addressed the different views presented by participants with the conclusion of producing a research-driven combination of different interventions for the control of tick tick-borne diseases.Fil: Estrada Peña, Agustín.
