The Mighty Bt: Interactions between pests and pesticidal proteins from Bacillus thuringiensis
2022
Bacillus thuringiensis, también conocida como “Bt”, es una bacteria gram positiva que forma endosporas. Se trata de un organismo ubicuo, aunque se encuentra principalmente en el suelo o en ambientes con alta presencia de insectos. Fue aislada por primera vez en 1901 por el bacteriólogo Shigetane Ishiwata en muestras de intestino de gusanos de seda (Bombyx mori) infectados y fue apodada como “Sottokin- Bacillus” (“Bacilo de muerte súbita”) por la muerte que causaba cuando era ingerida por larvas de gusanos de seda. Pocos años después, el biólogo Ernst Berliner aisló B. thuringiensis de crisálidas de polilla mediterránea de la harina (Ephestia kuehniella) infectadas con esta bacteria en la pr…

Exposition continue à des mélanges de perturbateurs endocriniens
2012
Dans ce projet, il est question d’explorer les effets de mélanges de perturbateurs endocriniens sur plusieurs générations, en considérant des cibles différentes (appareil reproducteur, glande mammaire, os, dent, tissu adipeux, glandes salivaires, cerveau...) et adaptées à chaque âge pour essayer de mieux comprendre comment agissent des perturbateurs endocriniens, en particulier ceux qui interfèrent avec les hormones sexuelles. Parmi les questions majeures que se pose le scientifique, figurent celles de l’effet d’une exposition prolongée à des mélanges de perturbateurs endocriniens depuis la conception jusqu’à l’âge adulte, et de la possibilité que ces expositions aient des répercussions sur…
THE SCENOGRAPHY OF SERPOTTA STUCCOES REVISITED - MATERIAL AND FORM
2015
The material that lies beneath the smooth shining surface of the stuccoes of the Serpotta family who used to work in Sicily from 1670 to 1730, has been thoroughly studied in previous papers, disclosing the deep, albeit empirical, knowledge of materials science that guided the artists in creating their masterpieces. In this work, attention is focused on the solid perspective and on the scenographic sculpture by Giacomo Serpotta, who is acknowledged as the leading exponent of the School. The study deals with some particular works of the artist, the “small-scaled plastic theatres”, so-called “teatrini”, which he made for the San Lorenzo Oratory in Palermo. On the basis of archival documents an…
L’affresco con la Virgo lactans “in maestà” e la Trinità tricefala: un’opera castigliana?
2023
Nel saggio si approfondisce la lettura iconografica di un affresco tardo-gotico dell'ultimo quarto del XV secolo conservato nella chiesa di Santa Maria la Porta di Geraci Siculo (PA). La Madonna che allatta il Bambino, il tipo di trono architettonico in cui è posta e la presenza della rara iconografia della Trinità tricefala suggeriscono una matrice iberica, probabilmente castigliana The essay explores the iconographic interpretation of a late Gothic fresco from the last quarter of the 15th century preserved in the church of Santa Maria la Porta in Geraci Siculo (PA). The Madonna suckling the Child, the type of architectural throne on which she is placed and the presence of the rare iconogr…

Elaboration of a list of substances of interest as regards to a potential endocrine activity and prioritisation strategy for assessment
2021
Endocrine Disruptor Chemicals (EDCs) are substances that alter function(s) of the endocrine system and consequently cause adverse health effects. The endocrine system consists of many cells and tissues that interact with each other and the rest of the body by means ofhormones. This system is responsible for controlling a large number of processes in the body from gamete formation, to conception and early developmental processes such as organogenesis, and to most tissue and organ functions throughout life. EDCs interfere withendocrine function by many ways and, in doing so, lead to adverse effects on the health of humans and/or wildlife. Some of the observed health effects associated with ED…
Phenolic Profiles, Antioxidant and Anti-Inflammatory Activities of Hydrodistillation Wastewaters from Five Lamiaceae Species
2022
Distillation is the most widely used method to obtain an essential oil from plant material. The biomass used in the process is returned as a solid residue together with variable amounts of water rich in water-soluble compounds, which currently are not addressed to any further application. The scope of this work was to evaluate the phytochemical composition of wastewaters coming from hydrodistillation (DWWs) of five aromatic plants belonging to the Lamiaceae family, and to assess their in vitro antioxidant and anti-inflammatory activities. The phenolic profiles of the DWWs were determined by HPLC-DAD and HPLC-ESI/MS. Free radical scavenging ability, oxygen radical antioxidant capacity and su…
TRATTAMENTO DI SEDIMENTI MARINI MEDIANTE REATTORI BIOSLURRY: ANALISI DI PROCESSO E CARATTERIZZAZIONE MICROBIOLOGICA
2020
I sedimenti, elementi essenziali e dinamici di tutti i sistemi acquatici, rappresentano un potenziale serbatoio di sostanze tossiche di origine antropogenica. In ambiente marino, essi costituiscono un comparto ambientale estremamente complesso, con modalità di formazione, caratteristiche chimico-fisiche, organismi viventi e tipi di contaminazione estremamente variabili. In particolare, gli idrocarburi di origine petrolifera (indicati globalmente con la misura dei TPH - Total Petroleum Hydrocarbon) inquinanti prioritari particolarmente diffusi nelle aree fortemente industrializzate, tendono a rimanere intrappolati nei sedimenti per lunghi periodi di tempo; ciò li rende una fonte permanente d…
Nitrate and nitrite in the diet: How to assess their benefit and risk for human health
2015
Nitrate is a natural constituent of the human diet and an approved food additive. It can be partially converted to nitrogen monoxide, which induces vasodilation and thereby decreases blood pressure. This effect is associated with a reduced risk regarding cardiovascular disease, myocardial infarction, and stroke. Moreover, dietary nitrate has been associated with beneficial effects in patients with gastric ulcer, renal failure, or metabolic syndrome. Recent studies indicate that such beneficial health effects due to dietary nitrate may be achievable at intake levels resulting from the daily consumption of nitrate-rich vegetables. N-nitroso compounds are endogenously formed in humans. However…
