Refugee testimonies enacted : voice and solidarity in media art installations
2018
This article examines how two media art installations in which celebrity actors enact refugee storytelling create awareness of the complexities of representation and solidarity with refugees. The celebrity actor produces familiarity, or “audibility,” for contents of the stories. Yet at the same time, the familiarity of the actor alerts the visitor to the politics of listening. The artworks therefore produce the potential for ethical listening, which requires interrogation into the privileges of the listener. The artworks produce a kind of sociality different from that of typical celebrity advocacy. Instead of being at the center of attention, the actors’ presence draws critical attention to…
Resistance Training Induces Antiatherogenic Effects on Metabolomic Pathways
2019
Introduction: Arising evidence suggests that resistance training has the potential to induce beneficial modulation of biomarker profile. To date, however, only immediate responses to resistance training have been investigated using high-throughput metabolomics whereas the effects of chronic resistance training on biomarker profile have not been studied in detail. Methods: A total of 86 recreationally active healthy men without previous systematic resistance training background were allocated into i) a resistance training (RT) group (n=68, age 33 ± 7 years, body mass index (BMI) 28 ± 3 kg/m2 ) and ii) a non-RT group (n=18, age 31 ± 4 years, BMI 27 ± 3 kg/m2 ). Blood samples were collected at…
Expert Opinion on Three Phage Therapy Related Topics: Bacterial Phage Resistance, Phage Training and Prophages in Bacterial Production Strain

Expert Opinion on Three Phage Therapy Related Topics: Bacterial Phage Resistance, Phage Training and Prophages in Bacterial Production Strain
2018
Phage therapy is increasingly put forward as a “new” potential tool in the fight against antibiotic resistant infections. During the “Centennial Celebration of Bacteriophage Research” conference in Tbilisi, Georgia on 26–29 June 2017, an international group of phage researchers committed to elaborate an expert opinion on three contentious phage therapy related issues that are hampering clinical progress in the field of phage therapy. This paper explores and discusses bacterial phage resistance, phage training and the presence of prophages in bacterial production strains while reviewing relevant research findings and experiences. Our purpose is to inform phage therapy stakeholders such as po…
Characterization of the metabolic profile and identification of potential therapeutic targets in advanced prostate cancer patients
2023
INTRODUCCIÓN El cáncer de próstata (CaP) representa el segundo tumor en incidencia en hombres y es la quinta causa de muerte por cáncer a nivel global. El CaP es un tumor hormono-dependiente, que requiere de la activación del receptor de andrógenos (AR) para su proliferación. Clínicamente, se caracteriza por una gran variabilidad en su evolución, progresando desde una condición indolente hasta un fenotipo agresivo que puede diseminarse y metastatizar a los nodos linfáticos y huesos. Actualmente, el diagnóstico temprano del CaP se realiza mediante la determinación sérica del antígeno prostático específico (PSA) y el examen rectal digital (DRE). Si estas pruebas dan resultados anómalos y hay …

Photoinduced lethal and sublethal toxicity of retene, a polycyclic aromatic hydrocarbon derived from resin acid, to coregonid larvae
2004
A comparative investigation on the acute phototoxicity of retene to vendace (Coregonus albula) and whitefish (C. lavaretus), both having pelagial larvae in spring, was conducted. To test the concept of early warning of sublethal biomarkers in relation to lethality to posthatch stages, we examined the effects of ultraviolet-B (UV-B) and retene on the levels of cytochrome P4501A (CYP1A) and heat shock protein 70 (HSP70) by exposing the animals to elevated levels of these factors for 48 and 72 h, respectively. Whereas UV-B and retene on their own were not lethal, simultaneous retene and UV-B exposure caused very high mortality to both species. The median lethal concentration (LC50; i.e., the c…
Novel VAMPIRE algorithms for quantitative analysis of the retinal vasculature
2013
This paper summarizes three recent, novel algorithms developed within VAMPIRE, namely optic disc and macula detection, arteryvein classification, and enhancement of binary vessel masks, and their performance assessment. VAMPIRE is an international collaboration growing a suite of software tools to allow efficient quantification of morphological properties of the retinal vasculature in large collections of fundus camera images. VAMPIRE measurements are currently mostly used in biomarker research, i.e., investigating associations between the morphology of the retinal vasculature and a number of clinical and cognitive conditions.

Cholesterol homeostasis and retinal stress in anterior ischemic optic neuropathy
2016
Purpose: Anterior ischemic optic neuropathy (AION) is characterized by acute stress of retinal ganglion cells (RGC). Cholesterol-24S-hydroxylase (CYP46A1) is specifically expressed in RGC where it may exert neuroprotective properties by preventing from cholesterol accumulation via catalyzing the formation of 24S-hydroxycholesterol. Previous findings hypothesize the housekeeping importance of CYP46A1 in the maintenance of cholesterol in the retina. In order to better understand the role of CYP46A1 in the retina, we aimed to define whether CYP46A1 expression and 24S-hydroxycholesterol levels were modified during RGC stress in AION.Methods: Ninety nine male Sprague Dawley rats were randomized …
