Yumiko Kimura. Invenzione e geometria
2016
Il saggio prende in esame la ricerca artistica di Yumiko Kimura (Tokyo, 1961), artista specializzata in sculture in vetro che coniugano arte geometrica e ricerca della luce. Il contributo è stato realizzato in occasione della mostra "Universi geometrici", che ha presentato una selezione di opere dell'artista giapponese all’interno della Valle dei Templi di Agrigento e poi alla FAM gallery con il patrocinio del Museum of Geometric and MADI Art di Dallas e l'inserimento nelle celebrazioni ufficiali del 150° anniversario delle relazioni tra Giappone e Italia. The essay examines the artistic research of Yumiko Kimura (Tokyo, 1961), an artist specializing in glass sculptures that combine geometr…

Il Museo dell’Università. Dalla Pinacoteca della Regia Università di Palermo alla Galleria di Palazzo Abatellis
2016
Il catalogo, oltre a presentare le opere esposte in mostra, racconta la storia e il formarsi delle collezioni d'arte palermitane del Museo dell'Università di Palermo dagli inizi dell'Ottocento fino al 1867, quando prenderà vita il Museo Nazionale nella ex casa dei PP. Filippini all'Olivella, censendo globalmente le opere delle diverse donazioni.
Insect Immune Evasion by Dauer and Nondauer Entomopathogenic Nematodes
2021
The immune response of animals, including insects, is overcome by some parasites. For example, dauer larvae (DL) of the obligate entomopathogenic nematodes (EPNs) Heterorhabditis and Steinernema can invade insects, evade their defenses, and cause death. Although DL were long assumed to be the only infective stage of nematodes, recent reports suggest that L2-L3 larvae of facultative EPNs are also capable of killing insects. There are no studies, to our knowledge, about the role of nonimmunological barriers (the exoskeleton and its openings) in avoiding infection by DL and L2-L3 larvae, or whether these larval stages evade the host immune system in the same way. The objective of this study wa…

Data from: Microbiome symbionts and diet diversity incur costs on the immune system of insect larvae
2017
Communities of symbiotic microorganisms that colonize the gastrointestinal tract play an important role in food digestion and protection against opportunistic microbes. Diet diversity increases the number of symbionts in the intestines, a benefit that is considered to impose no cost for the host organism. However, less is known about the possible immunological investments that hosts have to make in order to control the infections caused by symbiont populations that increase due to diet diversity. By using taxonomical composition analysis of the 16S rRNA V3 region, we show that Enterococci are the dominating group of bacteria in the midgut of the larvae of the greater wax moth (Galleria mell…
Comparison among the responses of the greater wax moth, Galleria mellonella and red palm weevil Rhynchophorus ferrugineus to the entomopathogenic nem…
2013
The entomopathogenic nematode-bacterium complex of Steinernema-Xenorhabdus has high potential as lethal biological control agent against many insect pest species. The Red Palm Weevil (RPW) Rhynchophorus ferrugineus (Coleoptera: Curculionidae) is an important worldwide palm trees pest. This insect is a quarantined pest, accidentally introduced in Sicily in 2005. The pest is killed by Steirnenema carpocapsae, but nematodes are unable to reproduce in the RPW larvae. This research try to understand the reasons of the inability of S. carpocapsae to complete its life cycle in the host comparing what happens in one of the most suitable host, the greater wax moth, Galleria mellonella (Lepidoptera: …
Data from: Independent and interactive effects of immune activation and larval diet on adult immune function, growth and development in the greater w…
2018
Organisms in the wild are likely to face multiple immune challenges as well as additional ecological stressors, yet their interactive effects on immune function are poorly understood. Insects are found to respond to cues of increased infection risk by enhancing their immune capacity. However, such adaptive plasticity in immune function may be limited by physiological and environmental constraints. Here, we investigated the effects of two environmental stressors – poor larval diet and an artificial parasite-like immune challenge at the pupal stage – on adult immune function, growth and development in the greater wax moth (Galleria mellonella). Males whose immune system was activated with an …
Data from: A mechanistic underpinning for sigmoid dose-dependent infection
2016
Theoretical models of environmentally transmitted diseases often assume that transmission is a constant process, which scales linearly with pathogen dose. Here we question the applicability of such an assumption and propose a sigmoidal form for the pathogens infectivity response. In our formulation, this response arises under two assumptions: 1) multiple invasion events are required for a successful pathogen infection and 2) the host invasion state is reversible. The first assumption reduces pathogen infection rates at low pathogen doses, while the second assumption, due to host immune function, leads to a saturating infection rate at high doses. The derived pathogen dose:infection rate -re…
