Biomonitoring of Microcystin and Aflatoxin Co-Occurrence in Aquaculture Using Immunohistochemistry and Genotoxicity Assays

This work investigated the effects of co-occurring aflatoxin B-1 (AFB(1)) and microcystin (MC) in aquaculture, using immunohistochemistry and genotoxicity methods. Tilapia (Oreochromis niloticus) were exposed to AFB(1) by intraperitoneal and MC (cell extract of Microcystis aeruginosa) by intraperitoneal and immersion routes. The interaction of MC-AFB(1) was evaluated co-exposing the intraperitoneal doses. Blood samples were collected after 8, 24, and 48h to analyze the micronucleus frequency and comet score. The interaction of MC-AFB(1) showed a synergic mutagenic response by higher micronucleus frequency of co-exposed group. A slight genotoxic synergism was also observed in the comet score. Immunohistochemistry detected MC in al lthe fish liver tissues exposed to MC by intraperitoneal route, and only the immersed group with the highest dose of MC showed a positive response. Although MC was non-detectable in the edible muscle, the combination of immunohistochemistry with genotoxicity assay was an attractive biomonitoring tool in aquaculture, where the animals were frequently exposed to co-occurring synergic hazards.

A Facile synthesis of 3-Methylene-4-aryl-1,3,4,5-tetrahydro-benzo[b][1,4] di-azepin-2-ones and 3-arylemethylene-4,5-dihydro-3H-benzo[b][1,4]diazepin-2-ylamines

A simple and convenient synthesis of 3-methylene-4-aryl-1,3,4,5-tetrahydro-benzo[b][1,4] diazepin-2-ones was accomplished by the SN2 nucleophilic substitution of the acetates of Baylis-Hillman adducts of acrylate with 1,2-phenylenediamines followed by base-mediated intramolecular cyclization. On the other hand similar substrates derived from the Baylis-Hillman adducts of acrylonitrile via Pinner’s reaction leads to 3-arylmethylene-4,5-dihydro-3H-benzo[b][1,4]diazepin-2-ylamines in good yields..

Impaired CD19 expression and signaling, enhanced antibody response to type II T independent antigen and reduction of B-1 cells in CD81-deficient mice

The tetraspanin CD81 is ubiquitously expressed and associated with CD19 on B lymphocytes and with CD4 and CD8 on T lymphocytes. Analysis of mice with disrupted CD81 gene reveals normal T cells but a distinct abnormality in B cells consisting of decreased expression of CD19 and severe reduction in peritoneal B-1 cells. CD81-deficient B cells responded normally to surface IgM crosslinking, but had severely impaired calcium influx following CD19 engagement. CD81-deficient mice had increased serum IgM and IgA and an exaggerated antibody response to the type II T independent antigen TNP-Ficoll. These results suggest that CD81 is important for CD19 signaling and B cell function.

An inverse methodology for high-frequency RF coil design for MRI with de-emphasized B-1 fields

An inverse methodology for the design of biologically loaded radio-frequency (RF) coils for magnetic resonance imaging applications is described. Free space time-harmonic electromagnetic Green's functions and de-emphasized B-1 target fields are used to calculate the current density on the coil cylinder. In theory, with the B-1 field de-emphasized in the middle of the RF transverse plane, the calculated current distribution can generate an internal magnetic field that can reduce the central overemphasis effect caused by field/tissue interactions at high frequencies. The current distribution of a head coil operating at 4 T (170 MHz) is calculated using an inverse methodology with de-emphasized B-1. target fields. An in-house finite-difference time-domain routine is employed to evaluate B-1 field and signal intensity inside a homogenous cylindrical phantom and then a complete human head model. A comparison with a conventional RF birdcage coil is carried out and demonstrates that this method can help in decreasing the normal bright region caused by field/tissue interactions in head images at 170 MHz and higher field strengths.

Implementación sobre FPGA de un algoritmo de compresión de imágenes hiperespectrales bajo el estándar CCSDS 123.0-B-1

A lo largo de la historia, nuestro planeta ha atravesado numerosas y diferentes etapas. Sin embargo, desde finales del cretácico no se vivía un cambio tan rápido como el actual. Y a la cabeza del cambio, nosotros, el ser humano. De igual manera que somos la causa, debemos ser también la solución, y el análisis a gran escala de la tierra está siendo un punto de interés para la comunidad científica en los últimos años. Prueba de ello es que, cada vez con más frecuencia, se lanzan gran cantidad de satélites cuya finalidad es el análisis, mediante fotografías, de la superficie terrestre. Una de las técnicas más versátiles para este análisis es la toma de imágenes hiperespectrales, donde no solo se captura el espectro visible, sino numerosas longitudes de onda. Suponen, eso sí un reto tecnológico, pues los sensores consumen más energía y las imágenes más memoria, ambos recursos escasos en el espacio. Dado que el análisis se hace en tierra firme, es importante una transmisión de datos eficaz y rápida. Por ello creemos que la compresión en tiempo real mediante FPGAs es la solución idónea, combinando un bajo consumo con una alta tasa de compresión, posibilitando el análisis ininterrumpido del astro en el que vivimos. En este trabajo de fin de grado se ha realizado una implementación sobre FPGA, utilizando VHDL, del estándar CCSDS 123. Este está diseñado para la compresión sin pérdida de imágenes hiperespectrales, y permite una amplia gama de configuraciones para adaptarse de manera óptima a cualquier tipo de imagen. Se ha comprobado exitosamente la validez de la implementación comparando los resultados obtenidos con otras implementaciones (software) existentes. Las principales ventajas que presentamos aquí es que se posibilita la compresión en tiempo real, obteniendo además un rendimiento energético muy prometedor. Estos resultados mejoran notablemente los de una implementación software del algoritmo, y permitirán la compresión de las imágenes a bordo de los satélites que las toman.
