Affinity proteomics identifies novel functional modules related to adhesion GPCRs.
2019
Adhesion G protein-coupled receptors (ADGRs) have recently become a target of intense research. Their unique protein structure, which consists of a G protein-coupled receptor combined with long adhesive extracellular domains, suggests a dual role in cell signaling and adhesion. Despite considerable progress in the understanding of ADGR signaling over the past years, the knowledge about ADGR protein networks is still limited. For most receptors, only a few interaction partners are known thus far. We aimed to identify novel ADGR-interacting partners to shed light on cellular protein networks that rely on ADGR function. For this, we applied affinity proteomics, utilizing tandem affinity purifi…
Minors and Transexuality
2020
[ES] En el ámbito de la transexualidad los poderes públicos han ejercido desde un principio una política claramente restrictiva que ha requerido de años para poder abrirse a las nuevas necesidades y a la sociedad actual. Así, la normativa en la materia era totalmente excluyente de los menores de edad, considerándolos carentes de aptitud alguna para poder decidir sobre su identidad sexual y todo lo que ello conllevaba, quizá porque como afirman algunos autores “la finalidad básica de esa prohibición es la de garantizar que la decisión de la rectificación registral sea una decisión firme y coherente, evitando así cambios arbitrarios o no fundados en el sexo” (Vázquez-Pastor, 2010).Esta idea p…
Parallel algorithms for large-scale biological sequence alignment on Xeon-Phi based clusters
2016
Computing alignments between two or more sequences are common operations frequently performed in computational molecular biology. The continuing growth of biological sequence databases establishes the need for their efficient parallel implementation on modern accelerators. This paper presents new approaches to high performance biological sequence database scanning with the Smith-Waterman algorithm and the first stage of progressive multiple sequence alignment based on the ClustalW heuristic on a Xeon Phi-based compute cluster. Our approach uses a three-level parallelization scheme to take full advantage of the compute power available on this type of architecture; i.e. cluster-level data par…
Effects of resveratrol on eNOS in the endothelium and the perivascular adipose tissue
2017
Under physiological conditions, nitric oxide (NO) is produced in the vasculature mainly by the endothelial NO synthase (eNOS). Experiments using gene-disrupted mice have demonstrated that eNOS has antihypertensive, antithrombotic, and antiatherosclerotic effects. Recent studies show that eNOS is expressed not only in the endothelium but also in the perivascular adipose tissue (PVAT). Resveratrol prevents eNOS uncoupling and upregulates eNOS expression and activity. These effects of resveratrol are well established for the eNOS enzyme in the endothelium. Interestingly, resveratrol also improves PVAT function. However, a causal role for eNOS in the effects of resveratrol on PVAT function has …
Moral assessment of frozen human embryo adoption in the light of the Magisterium of the Catholic Church
2017
As the number of frozen human embryos continues to rise daily, with numbers not expected to fall, an answer must be found to this dilemma. Four possible solutions have been suggested: a) thaw the embryos and allow them to perish; b) thaw them and donate them for biomedical research; c) thaw them and donate them in adoption; and d) leave them frozen indefinitely. This paper will evaluate the morality of these four possible solutions, particularly frozen human embryo adoption in the light of the Magisterium of the Catholic Church, which in its Instruction Dignitas Personae, appears to have opted to consider this practice as illicit. We also review the various stances of expert moralists in fa…

Drift and evolutionary forces
2016
This arride analyzes the view of evolutionary theory as a theory of forces. The analogy with Newtonian mechanics has been challenged due to the alleged mismatch between drift and the other evolutionary forces. Since genetic drifr has no direction severa! authors tried to protect its status as a force: denying its lack of directionality, extending the notion of force and looking for a force in physics which also lacks of direction. I analyse these approaches, and although this strategy finally succeeds, this discussion overlooks the crucial point on the debate between causalists and statisticalists: the causal status of evolutionary theoty.; El presente artículo analiza la visión de la teorí…
“Good translating is very hard work”
2021
Abstract Upon immigrating to New Zealand in 1937, Austrian-born philosopher of science Karl Raimund Popper lived and worked in the English-speaking world, where he published his major works in English. Life events forced him to engage in various forms of self-translation around the same time that he began earnestly working on translating Presocratic philosophical fragments into English. While he rejected language wholesale as an object of philosophical reflection, translation became an exception, a privileged occasion for philosophical reflection on language. This article reads Popper’s thoughts on translation in the context of previously unpublished correspondence between Popper and potent…
What is an indirect speech act?
2019
Abstract The notion of an indirect speech act is at the very heart of cognitive pragmatics, yet, after nearly 50 years of orthodox (Searlean) speech act theory, it remains largely unclear how this notion can be explicated in a proper way. In recent years, two debates about indirect speech acts have stood out. First, a debate about the Searlean idea that indirect speech acts constitute a simultaneous realization of a secondary and a primary act. Second, a debate about the reasons for the use of indirect speech acts, in particular about whether this reason is to be seen in strategic advantages and/or observation of politeness demands. In these debates, the original pragmatic conception of sen…
Divanes, gurús y trastornos mentales. El origen y los peligros de la pseudopsicología clínica
2017
Pseudoscience is alarmingly present in the context of clinical psychology and is also very dangerous. As a set of pseudoscientific ideas, clinical pseudopsychology has a peculiar characteristic: it has established an entire tradition parallel to psychology, with numerous branches and interrelated theoretical and practical developments. In this paper we will review that tradition, from pseudoscientific hypnosis to psychoanalysis, and from New Age to present-day neuropseudoscience. We will then review some of the dangers of pseudoscience related to mental disorders.
