Per favore, non chiamatelo cibo per cani
2017
Fra uomo e cane esiste quello che potremmo chiamare un patto nutrizionale, un accordo del tutto implicito che, per tramite del cibo, li lega. Come fare allora a conoscere i termini di tale patto? Come ricostruire le tante potenziali logiche che possono governarlo? Come capire insomma cosa può essere un cane per una persona e viceversa? Due modi di affrontare la questione sono evidentemente quelli dell’etologia e dell’antropologia, che cercano di risolvere il problema da un lato guardando agli animali, al modo in cui si comportano e imparano, capiscono e si esprimono, dall’altro alle comunità umane, e al ruolo che di volta in volta queste creature assumono al loro interno. L’approccio semiot…
Zoosemiotica 2.0. Forme e politiche dell'animalità
2017
Questo volume ha tre direzioni di discorso. Innanzitutto, un dialogo fra la semiotica e le altre discipline interessate agli studi animali: la filosofia, la filosofia del linguaggio e della mente, le scienze umane e sociali, le scienze cognitive e le neuroscienze. Non a caso molti degli interventi contenuti in questo volume non sono di semiologi ma di filosofi, sociologi, antropologi, linguisti, filologi, letterati etc. In secondo luogo, una discussione interna alla semiotica, nel passaggio dalla zoosemiotica 1.0 (tradizionalmente più interessata ai linguaggi e alle forme di comunicazione delle diverse specie animali) alla zoosemiotica 2.0, di conserva con altri settori a prima vista oppost…
Bcl-xL as a Modulator of Senescence and Aging
2021
Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…

Mucin 1 deficiency mediates corticosteroid insensitivity in asthma
2019
BACKGROUND: The loss of corticosteroid efficacy is an important issue in severe asthma management and may lead to poor asthma control and deterioration of airflow. Recent data indicate that Mucin 1 (MUC1) membrane mucin can mediate corticosteroid efficacy in chronic rhinosinusitis, but the role of MUC1 in uncontrolled severe asthma is unknown. The objective was to analyze the previously unexplored role of MUC1 on corticosteroid efficacy in asthma. METHODS: Mucin 1 expression was evaluated by real-time PCR in human bronchial epithelial cells (HBEC) and blood neutrophils from uncontrolled severe asthma (n=27), controlled mild asthma (n=16), and healthy subjects (n=13). IL-8, MMP9, and GM-CSF …
Sex Allocation Theory for Facultatively Sexual Organisms Inhabiting Seasonal Environments: The Importance of Bet Hedging
2018
Adaptive explanations for dormancy often invoke bet hedging, where reduced mean fitness can be adaptive if it associates with reduced fitness variance. Sex allocation theory typically ignores variance effects and focuses on mean fitness. For many cyclical parthenogens, these themes become linked, as only sexually produced eggs undergo the dormancy needed to survive harsh conditions. We ask how sex allocation and the timing of sex evolve when this constraint exists in the form of a trade-off between asexual reproduction and sexual production of dormant eggs—the former being crucial for within-season success and the latter for survival across seasons. We show that male production can be tempo…
The Impact of Adolescent Internet Addiction on Sexual Online Victimization: The Mediating Effects of Sexting and Body Self-Esteem
2021
Adolescents’ problematic use of the internet and the risk of sexual online victimization are an increasing concern among families, researchers, professionals and society. This study aimed to analyze the interplay between adolescents’ addiction to social networks and internet, body self-esteem and sexual–erotic risk behavior online: sexting, sextortion and grooming. While sexting refers to the voluntary engagement in texting sexual–erotic messages, sextortion and grooming are means of sexual–erotic victimization through the use of the internet. Participants were 1763 adolescents (51% girls), aged 12 to 16 years (M = 14.56
New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)
2021
We report and describe new Chirocephalus diaphanus Prévost, 1803 gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance. Our material has three specimens that are specifically deformed on the left side of the head.
How Geography and Climate Shaped the Genomic Diversity of Italian Local Cattle and Sheep Breeds
2022
International audience; Understanding the relationships among geography, climate, and genetics is increasingly important for animal farming and breeding. In this study, we examine these inter-relationships in the context of local cattle and sheep breeds distributed along the Italian territory. To this aim, we used redundancy analysis on genomic data from previous projects combined with geographical coordinates and corresponding climatic data. The effect of geographic factors (latitude and longitude) was more important in sheep (26.4%) than that in cattle (13.8%). Once geography had been partialled out of analysis, 10.1% of cattle genomic diversity and 13.3% of that of sheep could be ascribe…
