Electrochemical detection of nitric oxide in plant cell suspensions
2016
SPE IPM UB; Nitric oxide is a hydrophobic radical acting as a physiological mediator in plants. Because of its unique properties, the detection of NO in plant tissues and cell suspensions remains a challenge. For this purpose, several techniques are used, each having certain advantages and limitations such as interferences with other species, questionable sensitivity, and/or selectivity or ex situ measurement. Here we describe a very attractive approach for tracking NO in plant cell suspensions using a NO-sensitive homemade platinum/iridium-based electrochemical microsensor. This method constitutes the absolute real-time proof of the production of free NO in physiological conditions.
EUNIS Habitat Classification: Expert system, characteristic species combinations and distribution maps of European habitats
2020
Aim The EUNIS Habitat Classification is a widely used reference framework for European habitat types (habitats), but it lacks formal definitions of individual habitats that would enable their unequivocal identification. Our goal was to develop a tool for assigning vegetation-plot records to the habitats of the EUNIS system, use it to classify a European vegetation-plot database, and compile statistically-derived characteristic species combinations and distribution maps for these habitats. Location Europe. Methods We developed the classification expert system EUNIS-ESy, which contains definitions of individual EUNIS habitats based on their species composition and geographic location. Each ha…
Man-made garbage pollution on the Mediterranean coastline
1991
Abstract Measurements of persistent litter on 13 beaches in Spain, Italy (Sicily), Turkey, Cyprus and Israel between 1988 and 1989 show that plastic items are the most abundant in the litter composition, followed by wood, metal and glass items. Remnants of fishing gear are rather rare. It appears that the quantity of litter on a beach is inversely related to its geographical distance to a population center and directly related to the number of visitors frequenting it. Seasonal fluctuations in coastal litter are caused by storm waves which wash the litter landward, leaving the beach clean during winter, and by bathers who pollute it during summer. Based on the nature of the garbage, there ar…
Could male tergal secretions be considered as a nuptial gift in the Madeira cockroach?
2008
International audience; Many male insects provide somatic nuptial gifts that may strongly influence reproductive fitness, ensuring effective copulation or mediating paternal resource benefits in offspring. Although the courtship feeding behaviour on tergal gland secretions has been described in numerous cockroaches, studies on the function of these so-called nuptial gifts are lacking in this group. In this study, we examined, in the Madeira cockroach, Leucophaea maderae, the functional significance of tergal secretions by manipulating their availability on the back of males. We tested whether male tergal secretions function as a form of mating effort, and/or as a form of paternal investment…
Galectin-3 Released by Pancreatic Ductal Adenocarcinoma Suppresses γδ T Cell Proliferation but Not Their Cytotoxicity
2020
Pancreatic ductal adenocarcinoma (PDAC) is characterized by an immunosuppressive tumor microenvironment with a dense desmoplastic stroma. The expression of β-galactoside-binding protein galectin-3 is regarded as an intrinsic tumor escape mechanism for inhibition of tumor-infiltrating T cell function. In this study, we demonstrated that galectin-3 is expressed by PDAC and by γδ or αβ T cells but is only released in small amounts by either cell population. Interestingly, large amounts of galectin-3 were released during the co-culture of allogeneic in vitro expanded or allogeneic or autologous resting T cells with PDAC cells. By focusing on the co-culture of tumor cells and γδ T cells, we obse…
Aberrantly Expressed Embryonic Protein NODAL Alters Breast Cancer Cell Susceptibility to γδ T Cell Cytotoxicity
2020
Gamma delta (γδ) T cells kill transformed cells, and increased circulating γδ T cells levels correlate with improved outcome in cancer patients; however, their function within the breast tumor microenvironment (TME) remains controversial. As tumors progress, they begin to express stem-cell associated proteins, concomitant with the emergence of therapy resistant metastatic disease. For example, invasive breast cancers often secrete the embryonic morphogen, NODAL. NODAL has been shown to promote angiogenesis, therapy resistance and metastasis in breast cancers. However, to date, little is known about how this secreted protein may interact with cells in the TME. Herein we explore how NODAL in …
Guía para la incorporación de la perspectiva de género en la docencia en Sociología, Economía y Ciencias Políticas
2019
Sociology has constructed a male worldview that entails a biased interpretation of social reality. For its part, the traditional economy has made invisible the dependence of the commercial sphere of the domestic sphere. And in the field of political science, we also find many gender biases in basic concepts such as justice, equality or citizenship. This article, based on the work done by the authors in the Guia per a una docència universitària amb perspectiva de gènere de Sociologia, Economia i Ciència Política, offers some proposals, teaching resources and consultation tools to introduce the gender perspective in teaching, knowledge transfer and research in these disciplines.
Kirjallinen readymade 1960-luvun Suomessa
2017
Artikkeli käsittelee readymade-taiteen ja löydettyjen teosten (found object, objet trouvé) vastineita 1960-luvun kotimaisessa kirjallisuudessa. Aineisto koostuu viiden tekijän – Väinö Kirstinän, Kari Aronpuron, Kalevi Lappalaisen, Eeva-Liisa Mannerin ja M. A. Nummisen – teksteistä. Kirjallisia readymadejä käytettiin aikakauden kirjallisuudessa rinnakkain muiden kokeellisten ja taiteidenvälisten menetelmien kanssa. Artikkeli selvittelee, minkälainen ilmiö kirjallinen readymade on toisaalta 1960-luvun kontekstissa, toisaalta laajemmassa kirjallisuushistoriallisessa kontekstissa? Miten se suhteutuu alkuperäisiin readymadeihin, miten Marcel Duchampin pohdinnat ja käsitteellistykset sopivat kirj…
La delimitación del concepto de daño moral: un estudio de la cuestión en el ordenamiento jurídico español.
2021
El presente estudio tiene como objetivo realizar una aproximación al concepto de daño moral en el derecho español porque, a diferencia del daño patrimonial, el Código Civil no proporciona un concepto sobre él. Para la articulación de un concepto de daño moral es necesario analizar los supuestos de reconocimiento legal, la interpretación que los órganos judiciales han hecho y el tratamiento proporcionado en los Principios de derecho contractual europeo y de derecho de daños europeo. El trabajo finaliza con una valoración sobre la actual configuración del daño moral. The present study aims to make an approximation to the concept of non-pecuniary damage in Spanish law because, unlike property …
Análisis jurisprudencial de la legitimación pasiva de las entidades financieras en las reclamaciones realizadas por consumidores derivadas de una com…
2021
Consumers, who acquired real estate through a deed of sale with a mortgage subrogation, have made numerous claims against the financial entities. They request the nullity of the clause that imposes upon them all the expenses cause by the notarial deed. Financial entities have alleged that they do not have the capacity to be sued. Courts decisions have been diverse.
