Fish β-parvalbumin acquires allergenic properties by amyloid assembly

PRINCIPLES: Amyloids are highly cross-β-sheet-rich aggregated states that confer protease resistance, membrane activity and multivalence properties to proteins, all essential features for the undesired preservation of food proteins transiting the gastrointestinal tract and causing type I allergy. METHODS: Amyloid propensity of β-parvalbumin, the major fish allergen, was theoretically analysed and assayed under gastrointestinal-relevant conditions using the binding of thioflavin T, the formation of sodium dodecyl sulphate- (SDS-) resistant aggregates, circular dichroism spectroscopy and atomic force microscopy fibril imaging. Impact of amyloid aggregates on allergenicity was assessed with dot blot. RESULTS: Sequences of β-parvalbumin from species with commercial value contain several adhesive hexapeptides capable of driving amyloid formation. Using Atlantic cod β-parvalbumin (rGad m 1) displaying high IgE cross-reactivity, we found that formation of amyloid fibres under simulated gastrointestinal conditions accounts for the resistance to acid and neutral proteases, for the presence of membrane active species under gastrointestinal relevant conditions and for the IgE-recognition in the sera of allergic patients. Incorporation of the anti-amyloid compound epigallocatechin gallate prevents rGad m 1 fibrillation, facilitates its protease digestion and impairs its recognition by IgE. CONCLUSIONS: the formation of amyloid by rGad m 1 explains its degradation resistance, its facilitated passage across the intestinal epithelial barrier and its epitope architecture as allergen.Peer Reviewe

Influence of methane and carbon monoxide in the volumetric behaviour of the anthropogenic CO2: Experimental data and modelling in the critical region

Density measurements of the systems CO 2 + CH 4 at T = 304.21 K and CO 2 + CO at T = 304.21 and 308.15 K were carried out at pressures and compositions of interest in the process of transport and storage of CO 2 (CCS technology): P = 0.1 to 20 MPa, and xCO 2 ≥0.97. From the experimental P––T –xCO 2 data, we have studied the dependence of the isothermal compressibility, the excess molar volume, and the par- tial molar volume of the solute with composition, pressure and temperature within the critical region. We have modelled the volumetric behaviour of these systems with Peng–Robinson, PC-SAFT and GERG Equations of State, thus validating these equations under the conditions considered. Furthermore, we have confirmed the weakly attractive behaviour of these systems by performing a study of the interac- tions between solvent molecules, CO 2 , and those of the solute, CO or CH 4 , using the Krichevskii Function concept and the Kirkwood–Buff Theory. Finally, we have quantified the influence of small amounts of CH 4 and CO in the transport of anthropogenic CO 2 through several normalized parameters, related to the design and operation of the fluid transport process

EAACI Task force Clinical epidemiology of anaphylaxis: experts’ perspective on the use of adrenaline autoinjectors in Europe

Background Worldwide, guidelines recommend the use of adrenaline autoinjectors (AAIs) for self-medication in patients who experience severe allergic reaction. The European Medical Agency recommends the prescription of two AAIs, which should be carried by patients at all times. The European Academy of Allergy and Clinical Immunology guidelines propose to prescribe a second AAI under some defined conditions. In the present study, we aimed to examine the adherence to these guidelines and prescription behavior of allergy experts regarding the number of AAIs prescribed for a given patient. Methods A standardized questionnaire was applied to the participants of the 5th International Conference of the Network of Online Registration for Anaphylaxis (NORA e. V.). Twenty-six experts (medical doctors with at least 2 years of experience in the field of anaphylaxis) answered the questions regarding the number of autoinjectors prescribed and the reasons influencing their decisions. Results Sixty-eight percent of the experts usually prescribed one AAI, while 32% prescribed two. The pediatricians and physicians with less experience tended to prescribe two autoinjectors more frequently. The experts were more likely to prescribe two adrenaline autoinjectors if the patient was a child, had a previous severe reaction, had mastocytosis, asthma, cardiovascular disease, or high body weight, or lived far from the emergency department. Conclusion Our data confirm the lack of consensus regarding the number of AAIs to prescribe. Despite the European Medical Agency recommendation, the majority of allergy experts prescribed one autoinjector per patient. However, under distinct circumstances (e.g. mastocytosis, asthma, excess body weight, a history of severe anaphylaxis, or restricted access to immediate emergency), experts tended to prescribe more AAIs, which is in accordance with the European Academy of Allergy and Clinical Immunology guidelines

Improved regeneration of eggplant doubled haploids from microspore-derived calli through organogenesis

[EN] Doubled haploid (DH) technology allows for the production of pure lines, useful for plant breeding, through a one-generation procedure that reduces considerably the time and resources needed to produce them. Despite the advantages of microspore culture to obtain DHs, this technique is still insufficiently developed in eggplant, where DHs are produced from microsporederived calli through organogenesis. At present, very little is known on the best in vitro conditions to promote this process. This is why in this work we addressed the optimization of the process of regeneration of eggplant DH plants from microspore-derived calli. We evaluated the effect of different media compositions in the induction of organogenesis, in the promotion of shoot growth and elongation, and in root growth. According to our results, we propose the repeated subculture of the calli in MS medium with 0.2 mg/l IAA and 4 mg/l zeatin to produce shoots, and then the repeated subculture of the excised shoots in basal MS medium to promote their conversion into entire plantlets. This procedure yielded 7.6 plants per 100 cultured calli, which represents a *49 increase with respect to previous reports. We also evaluated by flow cytometry and SSR molecular markers the effect of these in vitro culture conditions in the rate of DH plant production, finding that*70 % of the regenerated plants were true DHs. These results substantially improve the efficiencies of DH recovery published to date in eggplant, and may be useful to those working in the field of eggplant doubled haploidy and breeding.We acknowledge Dr. Rosa Peiro for her statistical advice, and the staff of the COMAV greenhouses for their valuable help.

High-pressure speed of sound in pure CO2 and in CO2 with SO2 as an impurity using methanol as a doping agent

Reliable speed of sound, c, values in CO2- rich mixtures and pure CO2 are required for carbon capture and storage (CCS) technology but are difficult to determine, particularly at relatively high frequencies. We tested the suitability of methanol as doping agent to obtain accurate c values in CCS systems at 5 MHz. We measured c in seven CO2-rich, CO2 + methanol mixtures between 263.15 and 323.15 K and up to 196.30 MPa, and we extrapolated the values to obtain c in pure CO2. Additionally, we measured c from 263.15 to 373.19 K and up to 190.10 MPa in two CO2-rich, CO2 + SO2 mixtures with the same SO2 composition, which is of interest for CCS, with one mixture doped with methanol. We compared our results for pure CO2 with the literature and the Span and Wagner equation of state (EoS). We validated the PC-SAFT EoS and the modeling with the REFPROP 9 software for the mixtures by comparing the predicted values with our experimental data under the studied conditions. We conclude that methanol is a suitable doping agent to measure c in pure CO2 and CO2-rich mixtures. For the CO2 + SO2 mixtures, the effect of methanol on the experimental values is small and negligible for modeling

Just-In-Time eTraining Applied To Emergency Medical Services

While the applications of just-in-time training are more and more spread, the ubiquitous mobile technology has not found practical uses of this training strategy. As an original example of services for healthcare, we present in this work an application of eTraining that makes use of mobile telephones to transmit medical and on-site information content to emergency medical personnel that attend and emergency. The state-of-the-art in related technologies, overall architecture, and functioning of JITTER (for Just-In-Time Training for Emergency Responders) is described in this work.Universidad de Málaga.

Effects of growth conditions of donor plants and in vitro culture environment in the viability and the embryogenic response of microspores of different eggplant genotypes

[EN] Notwithstanding the importance of eggplant in global horticulture, doubled haploid production in this species is still far from being efficient. Although acknowledged to have a role in the efficiency of androgenesis induction, factors such as the growth conditions of donor plant or the in vitro culture environment have not been deeply explored or not explored at all in eggplant, which leaves room for further improvement. In this work, we investigated the effects of different in vivo and in vitro parameters on the androgenic performance of different eggplant genotypes, including two hybrids and a DH line. The in vivo parameters included the exposure of donor plants to different temperature and light conditions and to increased levels of boron. The in vitro parameters included the use of different concentrations of NLN medium components, sucrose and growth regulators, and the suspension of microspores at different densities. Our results showed that whereas greenhouse temperature variations or boron application did not to have a positive influence, greenhouse lighting influenced their viability, thereby conditioning the embryogenic response. Changes in different sucrose, salts and hormone levels had different effects in the genotypes studied, which correlated with their genetic constitution. Finally, we determined the best microspore density, different from that previously proposed. Our work shed light on the role of different factors involved in eggplant microspore cultures, some of them not yet studied, contributing to make microspore culture a more efficient tool in eggplant breeding.This work was supported by Grant AGL2017-88135-R to JMSS from Spanish MICINN, respectively, jointly funded by FEDER.
