Idrogeli intelligenti con sferoidi di cellule staminali adipose per la rigenerazione minimamente invasiva di ossa e cartilagini
L’esperienza raddoppiata. L’individuazione della memoria nell’era della transizione digitale.
2022
This contribution aims to reflect about the question of technology in Bernard Stiegler’s thought starting from a consideration about the original concepts of this branch in the twentieth-century philosophical thought with Gilbert Simondon and Martin Heidegger as founding fathers. A reflection halfway between metaphysics and politics to rethink the conditions of current state of existence and the possibilities in the future of overthrowing the hyper-industrial capitalist society.
El consum recreatiu d'esteroides anabolitzants: una perspectiva sociològica
2013
The present study aims to provide a sociological overview of anabolic steroid use in Valencia (Spain), with particular attention to social factors that promote and sustain the recreational use of this drug. We consider not only the extensively documented health risks, but also the social determinants associated with its use. The lack of studies, both in the European and Valencian contexts, which describe the extension and consumption patterns of anabolic steroids among young people, has inspired us to portray the sociological characteristics of the recreational anabolic steroid user, taking the main conceptual tools of the sociologist Pierre Bourdieu as a central reference point. Following …
Medikalisaatiokritiikki sosiaalityössä : katsaus teoriaan ja sosiaalityön tutkimukseen
2017
Suomalaisessa (terveys)sosiaalityön tutkimuksessa medikalisaatio eli yhteiskunnan lääketieteellistyminen ei ole ollut tyypillinen keskustelunaihe. Tutkimuksessani paikkaan puutetta tarkastelemalla anglosaksisissa sosiaalityön aikakauslehdissä käytyä medikalisaatiokeskustelua. Sovellan tulkitsevan käsitetutkimuksen tutkimustapaa ja systemaattisen kirjallisuuskatsauksen täsmällisempiä tutkimusmenetelmiä. Vastaan kysymyksiin, mihin yhteyksiin medikalisaation käsite sosiaalityön tutkimusartikkeleissa liitetään, ja mitä seurauksia medikalisaatiolla tutkimusartikkeleiden mukaan on. Analyysin tueksi erittelen klassikkoteosten avulla kahta sosiologisen medikalisaatiotutkimuksen tutkimusperinnettä, …
“Never shake thy gory locks at me” (Macbeth, III.iv.50-51): Objecting to Gestures in Macbeth
2018
International audience; Shakespeare's Macbeth displays a pattern of characters objecting to gestures, be it others' or their own. This includes Macbeth refusing to shake hands with his opponent before the battle, his words to Banquo's ghost quoted in the title above, Banquo's own puzzlement at the weird sisters' placing a finger over their lips, the doctor's suspicions at Lady Macbeth's rubbing her hands and sleepwalking, as well as Malcom's request that Macduff not pull his hat over his eyes. In many of these cases, gesture is pitted against speech, which seems to undermine the classically-derived ideal of "suit[ing] the word to the action, the action to the word" (Hamlet, 3.2.16-18). This…

Steroidal supramolecular metallogels
2020
The review deals with an expanding number of steroidal compounds that are capable of forming a metallogel providing a multitude of novel materials rich in their properties. The future of steroidal metallogels holds a myriad of potential applications as new intelligent materials. Detection of potentially harmful compounds without expensive instrumentation, entrapment of environmentally hazardous substances, and sensitive and selective nanomaterials represent only a few of these potential applications. This article reviews the design, synthesis, characterization, and applications of steroidal metallogels. peerReviewed
Acaricidal Activity of Bufadienolides Isolated from Drimia pancration against Tetranychus urticae, and Structural Elucidation of Arenobufagin-3-O-α-L…
2022
Chemical characterization of the bulbs of Drimia pancration was conducted to isolate four steroidal saponins (1–4). Earlier, we focused on the structural elucidation of compounds 1–3. Herein, by means of 1H-NMR, 13C-NMR, Nuclear Overhauser Effects (NOE), and 2D-NMR spectra, the full stereochemical structure of 4 is reported, and all the 1H and 13C signals are assigned. Compounds 1–4 were tested for their acaricidal properties against the two-spotted spider mite Tetranychus urticae. Our results showed excellent activity of compound 1, with an LD50 (µg/cm2) of 0.29 and a LD90 (µg/cm2) of 0.96, whereas compounds 2, 3, and 4 showed moderate activity. Furthermore, t…
Nuove dipendenze del terzo millennio: l'utilizzo di steroidi anabolizzanti come sostanza d'abuso
2005
Obiettivo. L'abuso di sostanze anabolizzanti si sta configurando come un problema di rilevanza psicosociale. L'uso di steroidi anabolizzanti in questi ultimi anni si è spostato dalla pratica sportiva professionale allo sport amatoriale e ad ambiti occupazionali particolari (buttafuori, modelli, ect.). La letteratura indica l'assuntore di steroidi come un poliassuntore che mette in atto condotte pericolose e aggressive per sé e per gli altri. L'obiettivo di questo studio è indagare le abitudini, le condotte di vita e il profilo psicologico di un gruppo di soggetti che frequentano centri sportivi nella città di Palermo (Italia), per verificare come l'utilizzo sconsiderato di sostanze anaboliz…
Basal Endogenous Steroid Hormones, Sex Hormone-Binding Globulin, Physical Fitness, and Health Risk Factors in Young Adult Men.
2018
Purpose: Few large-scale population-based studies have adequately examined the relationships between steroid hormones, health status and physical fitness. The purpose of the study was to describe the relationship of serum basal endogenous steroid hormones (testosterone, TES; empirical free testosterone, EFT; cortisol, COR) and sex hormone-binding globulin (SHBG) to body composition, cardiovascular risk factors, and physical fitness in young healthy men. Methods: Male reservists (25 ± 4 years, N = 846) participated in the study. Basal TES, EFT, COR, and SHBG were measured in morning fasted blood. Stepwise regression analyses were used to examine associations between individual hormones to fo…
