Glycoconjugate secretion in human airways in vitro: effects of epithelium removal.

The aim of this study was to examine glycoconjugate secretion in human airways with and without an epithelium. Glycoconjugate release in supernatants derived from human airways in vitro was determined using an ELISA assay with an anti-human mucin monoclonal antibody (MAb 3D3). This monoclonal antibody reacted strongly with Le(b) antigen but also recognized in vitro Le(a) and Le(y) determinants. In 11 of the 34 different lung samples (32%) studied the glycoconjugate levels were below the threshhold of detection for this assay. The mean basal secretion of glycoconjugates in human airways in vitro was 100+/-28 microg/g tissue (Period I; n = 23 different lung samples). The amount of glycoconjugate measured in the medium derived from human isolated bronchial ring preparations did not change under control conditions during the course of the experimental procedure (Period I; 128+/-46 microg/g tissue and Period II; 159 +/-48 microg/g tissue; n = 13 paired lung samples). In the supernatants of airway preparations with an intact epithelium the amount of glycoconjugates detected was 90+/-38 microg/g tissue (Period I; n = 12 different lung samples) and removal of the epithelium did not alter this basal glycoconjugate release (94+/-60 microg/g tissue: Period I, n = 8 different lung samples). The absence of the epithelial layer was confirmed by histological evaluation. Methacholine (100 microM) induced a 10- and four-fold increase in glycoconjugate release from airways with and without an epithelium, respectively. In contrast, in preparations with an epithelium, LTD4 (10 microM) and anti-IgE (dilution: 1/1000) did not cause an increase of glycoconjugate release. The methacholine difference between airways with and without an epithelium was not significantly different (P > 0.10). However, a treatment with atropine (100 microM) prevented the increase of glycoconjugate release in preparations with an epithelium. These data derived from a limited number of experiments suggest that the epithelium may not regulate the basal or stimulated release of glycoconjugates from isolated human airways

Bio-potential noise of dry printed electrodes: physiology versus the skin-electrode impedance

Objective. To explore noise characteristics and the effect physiological activity has on the link between impedance and noise. Approach. Dry-printed electrodes are emerging as a new and exciting technology for skin electro-physiology. Such electrode arrays offer many advantages including user convenience, quick placement, and high resolution. Here we analyze extensive electro-physiological data recorded from the arm and the face to study and quantify the noise of dry electrodes, and to characterize the link between noise and impedance. In particular, we studied the effect of the physiological state of the subject (e.g. rapid eye movement sleep) on noise. Main results. We show that baseline noise values extracted from dry electrodes in the arm are in agreement with the Nyquist equation. In the face, on the other hand, the measured noise values were higher than the values predicted by the Nyquist equation. In addition, we studied how different electrode properties affect performances, including electrode size, shape, and material properties. Significance. Altogether, the results presented here provide a basis for understanding dry electrode performances and substantiate their great potential in electro-physiological investigations

Migración de pescadores artesanales en la pesquería de pequeños peces pelágicos en África occidental: tendencias actuales y desarrollo

This study sought to present the evolutions and new trends of migrant fishing targeting small pelagics in West Africa from fishing to consumption stage. The work involved the characterization of migrant fishers targeting small pelagics in West Africa (country of origin, fishing gear and target species), modalities of access to resources, estimation of their catches and finally the assessment of the impact in the host countries. This work was useful to analyse changes in terms of the actors involved, the volumes and values of catches, and forms of valorisation and marketing of products from the migrant sectors over the period 2008-2018. Overall, the quantities of pelagic fish caught by migrant fishermen were increasing. The production of small pelagic by migrant fisheries has almost doubled over a decade, from an estimated of 180,000 t over the period 2008-2012, to a current estimated production of almost 324,500 t. More than 50% of this production was sold on the market in fresh or frozen form. More than 75,000 t (22%) and 94,000 t (28%) were destined for artisanal and industrial processing, respectively. Migrant fisheries thus supply more to industrial processing than to artisanal processing. Indeed, migrant fisheries have contributed over the last ten years to the emergence of fishmeal factories in West Africa. However, despite their significant evolution in terms of catch volumes and values, migrant fisheries still operate outside of legislative frameworks and without being explicitly accounted for in national statistics. Moreover, conflicts are increasingly important given the current tensions and issues surrounding the exploitation of small pelagic fish in West Africa. This work recommends the development of a common management plan for migrant fishers in the countries of the Sub-Regional Fisheries Commission (SRFC) and the West Central Gulf of Guinea Fisheries Committees (WCGC).Este estudio buscó presentar las evoluciones y las nuevas tendencias de la pesca migratoria dirigida a los pequeños peces pelágicos en África occidental desde los caladeros de pesca hasta los centros de consumo. El trabajo consistió en caracterizar a los pescadores migrantes que se dirigen a estas pesquerías en África Occidental (país de origen, artes de pesca y especies objetivo), presentando las modalidades de acceso a los recursos, estimando sus capturas y evaluando el impacto en los países anfitriones. Este trabajo permitió analizar los cambios en cuanto a los actores involucrados, los volúmenes y valores de las capturas, así como las formas de valorización y comercialización de los productos de los sectores migrantes durante el período 2008-2018. En general, las cantidades de peces pelágicos capturados por los pescadores migrantes están aumentando. La producción de las pesquerías migratorias de estos pequeños peces pelágicos casi se ha duplicado en una década, desde un promedio de 180.000 t durante el período 2008-2012, a una producción promedio actual de casi 324.500 t. Más de 50% de esta producción se vende en el mercado en forma fresca o congelada. Más de 75.000 t (23%) y 94.000 t (28%) se destinaron al procesamiento artesanal e industrial, respectivamente. Así, las pesquerías migratorias suministran más al procesamiento industrial que al procesamiento artesanal. Consecuentemente, las pesquerías migratorias han contribuido en los últimos diez años al surgimiento de fábricas de harina de pescado en África Occidental. Además, su contribución a las economías locales es cada vez más importante. Sin embargo, a pesar de su importante evolución en términos de volúmenes y valores de captura, las pesquerías migratorias todavía operan fuera de los marcos legislativos y no son contabilizadas explícitamente en las estadísticas nacionales. Además, los conflictos son cada vez más profundos dadas las tensiones actuales y los problemas que rodean la explotación de pequeños peces pelágicos en África occidental. Este trabajo recomienda el desarrollo de un plan de gestión común para los pescadores migrantes en los países de la Comisión Subregional de Pesca (SRFC) y los Comités de Pesca del Golfo de Guinea Centro-Occidental (WCGC)

Ionic Polyimides: New High Performance Polymers for Additive Manufacturing

There is currently a very limited set of engineering polymers that have been demonstrated as viable for use in 3-D printing. Additive manufacturing of custom components will require a much larger array of polymers, especially those with physical, thermal, chemical, and mechanical properties that can be tailor-made. The development of Ionic Polyimides offers a solution to this shortage by combining the well understood and widely accepted properties of conventional polyimides, with a new approach to polymer synthesis. Polyimides and polymeric ionic liquids (poly(ILs)) are at the forefront of advanced polymer materials, each with their own set of advantages and disadvantages. While it is clear that more types of polymer materials are needed for fused deposition modeling (FDM) additive manufacturing, there is a need to explore these classes of materials. The synthesis process developed by the Bara Research Group at the University of Alabama allows full control over polymer structure, nanostructure, thermal, electrical, and physical properties making them a prime candidate for use in the additive manufacturing process. Furthermore, the new process allows us to tailor-make a high strength polymer that can be used to fabricate filament feedstock instead of pellets for 3D printing. The primary objective of this proposal is to determine the relationship between molecular structure, physical properties, and performance of ionic polyimides. Further, we seek to determine their utility as materials suitable for additive manufacturing of components used in aerospace vehicles, with an emphasis on characterizing and simulating their thermal behaviors and properties. This proposal addresses the need for fundamental research on a customizable polymer filament feedstock for 3-D printing with tailor-made properties potentially making it superior to the commercial blends offered in industry today. The deliverables for this project are the creation of a database that will detail the relationships between the molecular structure and physical properties for the ionic polyimide of interest (e.g. Tg/Tm (Glass Transition Temperature divided by Melting Point)) relative to different ionic polyimide structures). This new database will provide a road map to the development of the first generation of materials and ultimately proof-of-concept

Towards Precision Muonic X-Ray Measurements of Charge Radii of Light Nuclei

Precision studies of the properties of nuclei are essential both for understanding nuclear physics at low energy, and for confronting experiment and theory in simple atomic systems. Such comparisons advance our understanding of bound-state quantum electrodynamics and are useful for searching for new physics beyond the Standard Model. The energy levels of muonic atoms are highly susceptible to nuclear structure, especially to the RMS charge radius. The radii of the lightest nuclei ($Z=1,2$) have been determined with high accuracy via laser spectroscopy in muonic atoms, while those of medium mass and above, from X-ray spectroscopy with semiconductor detectors. In this communication we present a new experiment aiming at precision measurements of the radii of light nuclei $3 \leq Z \leq 10$ via single-photon energy measurements with cryogenic microcalorimeters; a quantum sensing technology capable of high efficiency and outstanding resolution for low-energy X-rays
