Evaluating the potential for evolutionary mismatch in Batesian mimics: A case study in the endangered smooth snake (Coronella austriaca)
2018
Many harmless organisms gain a survival advantage by mimicking venomous species. This is the case of the endangered smooth snake (Coronella austriaca), which mimics venomous vipers. Although this may protect the smooth snake against most of its natural predators, it may render them at greater risk of mortality from humans, who are more inclined to kill species, such as vipers, that they consider dangerous. This may cause an evolutionary mismatch, whereby humans may counteract the natural advantage of mimicry. We explore this possibility of evaluating the willingness of humans to kill smooth snakes versus the adder (Vipera berus), as well as their ability to discern them in the Åland Islands…
Construcción de puentes y avenidas fluviales: algunos debates técnicos en el academicismo ilustrado del Reino de Valencia
2020
Con el afianzamiento de las políticas reformistas y la consolidación de las academias de bellas artes, durante el último tercio del siglo XVIII se desarrolló una creciente polémica entre los arquitectos y los maestros de obra en torno a la proyección y diseño de obra civil, particularmente la relacionada con ambientes fluviales. En este artículo se valora, con diferentes ejemplos, la incidencia de este debate en la proyección de puentes y su capacidad de resistencia a las avenidas fluviales. During the last third of the 18th century, reformist policies and the consolidation of the fine arts academies were consolidated. This fact affected the architects and the master builders with a policy …
From waste to health: sustainable exploitation of grape pomace seed extract to manufacture antioxidant, regenerative and prebiotic nanovesicles withi…
2020
AbstractPomace seed extract loaded vesicles were prepared as promising technological and green solution to exploit agri-food wastes and by-products, and develop high value-added products for human health. An antioxidant extract rich in bioactive compounds (epicatechins, catechin, gallic acid, quercetin and procynidins) was obtained from the seeds isolated from the pomace of Cannonau red grape cultivar. The extract was incorporated into phospholipid vesicles ad hoc formulated for intestinal delivery, by combining them, for the first time, whit a maltodextrin (Glucidex). Glucidex-transfersomes, glucidex-hyalurosomes and glucidex-hyalutransferomes were prepared, characterized and tested. Gluci…
Optimized production and purification of Coxsackievirus B1 vaccine and its preclinical evaluation in a mouse model.
2017
Coxsackie B viruses are among the most common enteroviruses, causing a wide range of diseases. Recent studies have also suggested that they may contribute to the development of type 1 diabetes. Vaccination would provide an effective way to prevent CVB infections, and the objective of this study was to develop an efficient vaccine production protocol for the generation of novel CVB vaccines. Various steps in the production of a formalin-inactivated Coxsackievirus B1 (CVB1) vaccine were optimized including the Multiplicity Of Infection (MOI) used for virus amplification, virus cultivation time, type of cell growth medium, virus purification method and formulation of the purified virus. Safety…
Polysorbate 80 controls Morphology, structure and stability of human insulin Amyloid-Like spherulites
2022
AbstractAmyloid protein aggregates are not only associated with neurodegenerative diseases and may also occur as unwanted by-products in protein-based therapeutics. Surfactants are often employed to stabilize protein formulations and reduce the risk of aggregation. However, surfactants alter protein-protein interactions and may thus modulate the physicochemical characteristics of any aggregates formed. Human insulin aggregation was induced at low pH in the presence of varying concentrations of the surfactant polysorbate 80. Various spectroscopic and imaging methods were used to study the aggregation kinetics, as well as structure and morphology of the formed aggregates. Molecular dynamics s…
Deconvolution procedure of the UV-vis spectra. A powerful tool for the estimation of the binding of a model drug to specific solubilisation loci of b…
2015
UV-vis-spectra evolution of Nile Red loaded into Tween 20 micelles with pH and [Tween 20] have been analysed in a non-conventional manner by exploiting the deconvolution method. The number of buried sub-bands has been found to depend on both pH and bio-surfactant concentration, whose positions have been associated to Nile Red confined in aqueous solution and in the three micellar solubilisation sites. For the first time, by using an extended classical two-pseudo-phases-model, the robust treatment of the spectrophotometric data allows the estimation of Nile Red binding constant to the available loci. Hosting capability towards Nile Red is exalted by the pH enhancement. Comparison between bin…
Conflicting conceptualisations of ‘democracy’ in the German Bundestag during the anti-nuclear demonstrations, 1995-2001
2018
A vigorous anti-nuclear movement emerged in Germany in the mid 1990s, when spent nuclear fuel elements began to be transported to the interim storage facility in Gorleben, Lower Saxony. Resistance to nuclear transportation continued to grow in strength throughout the 1990s. The protests expressed people’s distrust and lack of confidence in political institutions and decision-making processes. In the German Bundestag, these events relating to Gorleben caused significant political struggles over the principles and meanings of German democracy. Parliamentarians voiced competing counterarguments about the legitimacy of these demonstrations, on the one hand, and the legitimacy of the nuclear ene…

Sociālās mācīšanās un mēdiju platforma Edmodo skolēnu argumentēšanas prasmju attīstībai debatēm
2017
Projekta debašu līderu skola ietvaros, darba autore izveidoja debašu klubu Garkalnes Mākslu un vispārizglītojošajā vidusskolā. Pēc pirmajām tikšanās reizēm ar 7-9 klases skolēniem, darba autore konstatēja, ka viņiem trūkst argumentēšanas prasmes. Tika nolemts izmantot Edmodo platformu, lai palīdzētu skolēniem veicināt šīs prasmes. Pētījuma metode bija gadījuma pētījums Garkalnes Mākslu un vispārizglītojošajā vidusskolā no novembra 2016 līdz aprīlim 2017 un tajā piedalījās 8 skolēni. Pētījuma laikā tika analizētas pētījuma piezīmes, skolēniem tika plānotas un izsniegtas sešas anketas, veiktas divas intervijas un analizēti trīs debašu ieraksti. Balstoties uz pētījuma rezultātiem var secināt, …
