Mate preferences in Argentinean transgender people

2018

Transgender people provide a unique opportunity to examine the effect of biological sex versus gender identity on mating preferences. This study aimed at identifying the mate characteristics that are most and least valued by transgender people and at examining to what extent their biological sex or their gender identity determined their mate preferences. A convenience sample of 134 male‐to‐female (MTF) and 94 female‐to‐male (FTM) individuals from Argentina rated Buss's list of 18 mate attributes. Compared to FTM, MTF individuals placed significantly more emphasis on attractiveness and socioeconomic status, whereas FTM, more than MTF individuals, valued partners with a dependable character. …

Non-starter lactic acid bacteria used to improve cheese quality and provide health benefits

2010

Non-starter lactic acid bacteria (NSLAB) dominate cheese microbiota during ripening. They tolerate the hostile environment well and strongly influence the biochemistry of curd maturation, contributing to the development of the final characteristics of cheese. Several NSLAB are selected on the basis of their health benefits (enhancement of intestinal probiosis, production of bioactive peptides, generation of gamma-aminobutyric acid and inactivation of antigenotoxins) and are employed in cheese-making. This review describes the ecology of NSLAB, and focuses on their application as adjunct cultures, in order to drive the ripening process and promote health advantages. The scopes of future dire…

A Ciliary Motility Index for Activity Measurement in Cell Cultures With Respiratory Syncytial Virus

2018

[EN] Background: The respiratory epithelium is frequently infected by the respiratory syncytial virus, resulting in inflammation, a reduction in cilia activity and an increase in the production of mucus. Methods: In this study, an automatic method has been proposed to characterize the ciliary motility from cell cultures by means of a motility index using a dense optical flow algorithm. This method allows us to determine the ciliary beat frequency (CBF) together with a ciliary motility index of the cells in the cultures. The object of this analysis is to automatically distinguish between normal and infected cells in a culture. Results: The method was applied in 2 stages. It was concluded fro…

Effect of the conversion of mangroves into shrimp farms on carbon stock in the sediment along the southern Red Sea coast, Saudi Arabia

2019

The conservation of coastal ecosystems and specially mangroves ‘‘blue carbon’’ is receiving more attention as consequence of their recognition as high ecosystem carbon stocks and for the fact that these areas are undergoing land conversion. The aim of the present study is to evaluate the impact of land use changes due to conversion of mangroves to shrimp farms on the bulk density (SBD), organic carbon (SOC) concentration, and SOC stock in the sediments along the southern Saudi Arabian Red Sea coast. Shrimp farms and mangrove locations showed significant (P < 0.001) differences in SBD with high mean values in the sediments of shrimp farms. Shrimp farms and mangrove locations showed significa…

An innovative method for the detection of contaminant viral genome in cell cultures

2012

The use of cell cultures involves different fields of biology, from diagnosis to research. Moreover, technologies based on animal cells represent a useful tool to the development of biological products for the prophylaxis and therapy in humans and animals. Therefore, it is necessary to perform quality controls, including virological tests. Several tests performed in research laboratories are able to discriminate one or more viral species, but it is not possible to demonstrate the presence of contaminant viral genome with one non-specific method. The aim of this work consisted on the realization of a biomolecular method able to detect and to identify by sequencing extraneous viral genome in …

Physical, chemical and morphological changes of bread polyphenol extract on cellular cultures monolayer CaCo-2

2013

The effect on potential transepithelial electrics resistance (TEER) and the electronic scansion microscopy analysis (SEM) of CaCo-2 cells line monolayer could be one useful method to study the different antioxidant or pro-oxidant capacity values of different concentrations of the hydrolizated polyphenol extracts of bread made with wheat Sant’Agata cultivar (HBPE).The various concentrations of HBPE have been tested on culture in monolayer CaCo-2 cells seeded on polycarbonate filter, in the cell culture chamber (Ø 6.5 μm; area 0.33cm2; pore Ø 0.4 μm), at a density of 1.5x105 cells per filter and placed in a multiwells Falcon; the filter divided the chamber in apical and basal compartments tha…

Communication et Interculturation

2021

Interpersonal communication brings together individuals who try to make sense of one another in a given context. In this ongoing intersubjective process, they use culturally-structured knowledge and references to conjure up figures and styles rooted in identity-play. Whether in organisations, in the media, or in our open, cosmopolitan, liquid societies of late modernity, identities appear ever more present, ever more pressing. They are linked to the cultural traits that people use to “perform” and make sense of themselves and others in different social situations. The forms, figures and styles in circulation are mediated and updated through these everyday symbolic interactions, within a soc…

Co-construct territorial cultures

2015

International audience; Carrying out investigations in the framework of the scientific network INTI (International Network of Territorial Intelligence, http://inti.hypotheses.org/), the main idea is here to value the contribution of multiple approaches in territorial information and communication science that can be experienced there. Inspired by the triad of Pestalozzi, these experiences have applied and adapted the territorial engineering approach "Catalyse" in their territories.From the cooperative structuring of information to concrete initiatives of local change, communication processes make possible iterations between understanding and action, in which the analysis of the effects of s…
