Regulation of cuticular hydrocarbon profile maturation by Drosophila tanning hormone, bursicon, and its interaction with desaturase activity
2016
International audience; Shortly after emergence the exoskeleton (cuticle) of adult insects is rapidly expanded, hardened (sclerotized), and pigmented (melanized). In parallel with this process, the oenocytes, which are large polyploid cells located below the abdominal epidermis, secrete onto the cuticle a cocktail of cuticular hydrocarbons (CHs) and waxes. These improve the waterproofing of the cuticle, and also provide important chemosensory and pheromonal cues linked with gender, age, and species differentiation. The hardening and pigmentation of the new cuticle are controlled by the neurohormone, bursicon, and its receptor, encoded by the DLGR2 receptor, rickets (rk); by contrast, little…
desat1: A Swiss army knife for pheromonal communication and reproduction?
2012
International audience; The desat1 gene possesses an extraordinary-maybe unique-feature in the control of sensory communication systems: it codes for the two principal and complementary aspects-the emission and the reception-of Drosophila sex pheromones. These two complex aspects depend on separate genetic control indicating that desat1 pleiotropically acts on pheromonal communication. This gene also control other characters either related to reproduction and to osmoregulation. Such a functional pleiotropy may be related to the molecular structure of desat1 gene which combines a highly conserved coding region with fast evolving regulatory regions: It produces at least five transcripts all g…
Fauna Europaea: Hymenoptera - Apocrita (excl. Ichneumonoidea)
2015
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. Hymenoptera is one of the four largest orders of inse…
Fauna Europaea: Diptera – Brachycera
2015
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant multicellular European terrestrial and freshwater animals and their geographical distribution at the level of countries and major islands (east of the Urals and excluding the Caucasus region). The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing taxonomic specialists throughout Europe and is a unique (standard) reference suitable for many user c…
Trapping the Enemy: Vermamoeba vermiformis Circumvents Faustovirus Mariensis Dissemination by Enclosing Viral Progeny inside Cysts
2019
Viruses depend on cells to replicate and can cause considerable damage to their hosts. However, hosts have developed a plethora of antiviral mechanisms to counterattack or prevent viral replication and to maintain homeostasis. Advantageous features are constantly being selected, affecting host-virus interactions and constituting a harsh race for supremacy in nature. Here, we describe a new antiviral mechanism unveiled by the interaction between a giant virus and its amoebal host. Faustovirus mariensis infects Vermamoeba vermiformis, a free-living amoeba, and induces cell lysis to disseminate into the environment. Once infected, the cells release a soluble factor that triggers the encystment…
Insegnare a vedere problematicamente e l'isola di Mantegna
2018
Inquadrare il lavoro didattico e di ricerca di Carlo Ravagnati coincide con lo svelare una radice culturale dalla quale avviare un possibile ragionamento. Tale inizio trova riferimento in un passo tratto da "Architettura per i musei" di Aldo Rossi: " Bisogna arrivare a parlare delle nostre opere, del segno della nostra esperienza; penso sempre tra gli artisti e gli interpreti della cultura moderna che più mi hanno formato al libro di Raymond Roussel, "Comment j'ai écrit certains de mes livres". Questo libro è fondamentale in quanto teoria della composizione che vuole dominare tutti gli aspetti della creazione artistica. Domandarsi come ha fatto è la premessa e al contempo costituisce l'ener…
FEMALE GENITAL MUTILATIONS: GENITO-URINARY COMPLICATIONS AND ETHICAL-LEGAL ASPECTS
2015
Many women in the world are still undergoing female genital mutilations (FGMs) even if in almost all the countries, the practice of FGM is illegal. The increase of immigration, particularly from African Countries, to Europe, and Italy too, led to consider this phenomenon with particular attention and skill. All the operators in health services need to know the different types of FGMs and the related complications and the psychological and sexual sequels. Urological complications, in particular, are not rare and the changing anatomy of the external genital apparatus can also make the catheter insertion sometimes difficult. This review analyzes the epidemiology of FGMs, the reasons why the p…
Specificità femminili e maschili. Opinioni e aspettative di insegnanti di scuola secondaria di primo e secondo grado
2017
Le recenti ricerche psicologiche, pedagogiche e didattiche hanno accertato che gli alunni e le alunne apprendono e si comportano a scuola in modo diverso e che la probabilità di successo nello studio aumenta, per entrambi i sessi, quando gli insegnanti, nella loro attività didattica, tengono presenti le peculiarità maschili e femminili. È avvertita pertanto l’esigenza di studiare e diffondere le migliori esperienze didattiche sul modo pedagogicamente più valido di insegnare alle donne e agli uomini. In questa ricerca abbiamo voluto conoscere le opinioni di 232 docenti dell’ultimo anno di scuola secondaria di primo grado e dei primi due anni di scuola secondaria di secondo grado di tutte le …
