Boric acid toxicity to the German cockroach, Blattella germanica: Alterations in midgut structure, and acetylcholinesterase and glutathione S-transfe…
2006
0048-3575 doi: DOI: 10.1016/j.pestbp.2005.05.002; Oral toxicity of boric acid, an inorganic insecticide, was evaluated on German cockroach, Blattella germanica L. (Dictyoptera, Blattellidae). Newly emerged adults were exposed to various concentrations of boric acid incorporated into the diet. Results showed that treated insects exhibited toxic symptoms with a dose-dependent mortality. Histological study of midgut revealed alterations in the epithelial cells and a signiWcant increase in the epithelium thickness. In a second series of experiments, the compound was investigated on the activities of acetylcholinesterase (AChE) and glutathione S-transferases (GSTs). Data showed that the compound…
Social Wasps (Vespinae) in Urban Gardens and Woods
2020
Global change, including urbanization, affects species ecology. Social wasps (Vespinae) are ubiquitous in urban areas, which increases their encounters with humans. We studied social wasps in urban gardens and nearby urban woods in central Finland, using beer traps. Social wasps were common in gardens and woods, and overall wasp abundance was higher in the woods. Also, the most abundant and frequent species Vespula vulgaris was more abundant in the woods than in the gardens. Variation in the overall abundance and the abundance of V. vulgaris was great among trap locations, which likely results from wasps’ social nesting habits. Neither the abundance of all social wasps nor that of V. vulgar…
Can biological structures be natural and sustainable capsules?
2015
Flavor and fragrance molecules are used in many industrial fields such as food, cosmetics, tissues, pharmacy, agriculture (pheromones) etc. As most actives have a specific target and are fragile molecules, encapsulation processes have been developed for their use. These technologies are efficient to avoid loss of actives, dissemination out of the target and subsequent pollution, and to protect molecules up to their target. Several processes have been developed responding to the numerous situations encountered (e.g., protection against air, temperature, light, pH; masking or revealing sensorial properties of the molecule; release during the process, in the plate, in the mouth, etc.). However…
Could male tergal secretions be considered as a nuptial gift in the Madeira cockroach?
2008
International audience; Many male insects provide somatic nuptial gifts that may strongly influence reproductive fitness, ensuring effective copulation or mediating paternal resource benefits in offspring. Although the courtship feeding behaviour on tergal gland secretions has been described in numerous cockroaches, studies on the function of these so-called nuptial gifts are lacking in this group. In this study, we examined, in the Madeira cockroach, Leucophaea maderae, the functional significance of tergal secretions by manipulating their availability on the back of males. We tested whether male tergal secretions function as a form of mating effort, and/or as a form of paternal investment…
Component-Resolved Diagnosis of American Cockroach (Periplaneta americana) Allergy in Patients From Different Geographical Areas
2021
Background:Manifestation of respiratory allergy to American cockroach (Periplaneta americana) is prominent in the subtropical and tropical areas. However, co-existing perennial indoor inhalant allergies frequently compromise clinical diagnosis of cockroach allergy, and the analysis of sensitization pattern is limited by the lack ofPeriplanetaallergens widely available for component-resolved diagnostics (CRD).Objective:To evaluate a collection of previously described recombinantPeriplanetaallergens for CRD in cockroach allergy.Methods:A panel of nine recombinantPeriplaneta allergens (Per a 1–5, 7–10) was generated, purified, and subjected to physicochemical characterization by applying circu…
An Illustration to Ælfric’s De temporibus anni in Ælfwine’s Prayerbook
2020
L'articolo esamina un diagramma contenuto nel manoscritto London, British Library, Cotton Titus D.xxvii+xxvi, generalmente noto come 'Ælfwine’s Prayerbook'. Il diagramma, che si trova al fol. 21 v , è stato in genere interpretato come una rota incompleta, o delle maree o dei venti (dal momento che contiene solo 4 dei canonici 12 venti della tradizione scientifica medievale). Una analisi comparativa e dettagliata delle caratteristiche del diagramma, tuttavia, mostra come l'ipotesi della rota delle maree sia da rigettare in favore della teoria di una rota ventorum. Inoltre, l'analisi dei testi contenuti nel manoscritto rivela una stretta connessione tra il diagramma e il De temporibus anni di…

‘A Storehouse of Learned Vocabulary: the Abbo Glossaries in Anglo-Saxon England’,
2010
The entire textual transmission of a late ninth-century poem, the Bella Parisiacae urbis by Abbo of Saint-Germain-des-Prés, is indissolubly tied with glosses and glossaries. The peculiarity of its composition as well as its large circulation makes this poem a perfect case study for the role and development of medieval glossography. The essay is divided into three sections devoted to the relationship between the poem and the products of medieval glossography: 1. glossaries were a source of Abbo’s poem, which in turn was, from the very outset, provided with glosses; 2. in England the third book of Abbo’s poem became a source of glossaries itself, and, 3. in the course of its transmission, Abb…
'Glosse in volgare e in latino nei codici anglosassoni’
2012
Le glosse si collocano all’intersezione delle due attività del leggere e dello scrivere; costituiscono anche un punto d’incontro tra lingue diverse e tradizioni letterarie di differente matrice. Il saggio prende in esame queste confluenze partendo da esempi ripresi dalla produzione glossografica anglosassone, con riferimento alle glosse con interpretamenta sia in anglosassone (o antico inglese) sia in latino presenti nei codici vergati in Inghilterra fino a tutto l’XI sec. Tra le questioni affrontate: la definizione del corpus; la problematica delle glosse interlineari sparse e continue; le tipologie e le peculiarità dei glossari; la necessità di cogliere la specificità di ogni testo; le fo…
