Influence of gene action across different time scales on behavior.
2002
Genes can affect natural behavioral variation in different ways. Allelic variation causes alternative behavioral phenotypes, whereas changes in gene expression can influence the initiation of behavior at different ages. We show that the age-related transition by honey bees from hive work to foraging is associated with an increase in the expression of the foraging ( for ) gene, which encodes a guanosine 3′,5′-monophosphate (cGMP)–dependent protein kinase (PKG). cGMP treatment elevated PKG activity and caused foraging behavior. Previous research showed that allelic differences in PKG expression result in two Drosophila foraging variants. The same gene can thus exert different types of influe…
Age affects the metabolic rate of insect brain.
1984
Abstract Brains of adult insects can be isolated and studied vitro. In female blowflies the oxygen uptake of the brain is age dependent. A steady increase is followed by a precipitous decrease around the middle of the life span. These changes are accompanied by alterations of mitochondrial structure and deposits of lipofuscin-like material.
La pratica riflessiva nell’esperienza di tirocinio come strumento di formazione e orientamento alla professione di insegnante di sostegno di scuola s…
2022
A partire dall’approccio metodologico della Narrative Inquiry, è stata realizzata la raccolta e l’analisi di 418 relazioni di tirocinio di altrettanti tirocinanti in formazione che hanno frequentato nel periodo compreso tra gennaio e giugno 2021 il percorso di Specializzazione per le attività di sostegno per la Scuola secondaria di primo e secondo grado dell’Università degli Studi di Palermo. La ricerca intende mettere in risalto l’importanza della pratica riflessiva come dispositivo innovativo di sviluppo profes-sionale e orientamento sul proprio agire didattico, in una dimensione che coniuga le conoscenze teoriche e l’applicazione pratica delle stesse. L’analisi dei risultati conferma l’a…
Low-dose dopamine agonist administration blocks vascular endothelial growth factor (VEGF)-mediated vascular hyperpermeability without altering VEGF r…
2006
No specific treatment is available for ovarian hyperstimulation syndrome (OHSS), the most important complication in infertile women treated with gonadotropins. OHSS is caused by increased vascular permeability (VP) through ovarian hypersecretion of vascular endothelial growth factor (VEGF)activating VEGF receptor 2 (VEGFR-2). We previously demonstrated in an OHSS rodent model that increased VP was prevented by inactivating VEGFR-2 with a receptor antagonist(SU5416).However,duetoitstoxicity(thromboembolism) and disruption of VEGFR-2-dependent angiogenic processes critical for pregnancy, this kind of compound cannot be used clinically to prevent OHSS. Dopamine receptor 2 (Dp-r2) agonists, use…
Imidazole derivative KK-42 reduces ecdysteroid titers and interferes with reproductive processes in adult females of Tenebrio molitor
2004
0048-3575 doi: DOI: 10.1016/j.pestbp.2004.07.004; KK-42, an imidazole derivative considered as potent inhibitor of ecdysteroid biosynthesis, was tested on adult females of Tenebrio molitor. The compound was applied topically (0.1, 1, 5, and 10 μg/insect) on 0- or 2-day-old adult females or added to the culture medium (1 and 10 μM) of ovaries. To test the effect of KK-42 on the reproduction capacity, ovaries were explanted from 2- and 4-day-old females corresponding, respectively, to follicles at the beginning and the end of vitellogenesis. KK-42 treatment reduced the fecundity and the longevity of females, and in addition, it delayed oviposition and affected growth and development of oocyte…

Profilo dell'attività scientifica di Fabiola Ardizzone
2018
Si ripercorre l'attività scientifica della compianta Collega Fabiola Ardizzone, dai suoi esordi come allieva della Cattedra di Archeologia Cristiana dell'Università di Palermo, all'attività di insegnamento e di ricerca sul campo in qualità di Professore Associato. Il contributo dato da Fabiola Ardizzone agli studi sulla Tarda Antichità e sul Medioevo siciliani hanno riguardato molteplici direttrici di ricerca: dall'identificazione di nuove classi ceramiche alle modalità di organizzazione delle aree funerarie, dai problemi di topografia urbana all'archeologia dei cimiteri e ai problemi della produzione e circolazione delle produzioni ceramiche. The paper traces the scientific activity of Fab…
Enhancement of the Diversity of Pollinators and Beneficial Insects in Intensively Managed Vineyards
2021
Simple Summary The continuous intensification of agricultural production has resulted in higher yields and more yield security. However, these achievements went along with the substitution of heterogeneous agricultural landscapes by homogeneous ones with poor crop diversity, short crop rotations, and thanks to the high efficacy of modern herbicides and also to minimum in-crop diversity. A severe increase in plot size led to the elimination of ecologically valuable structural elements that had provided floral resources and nesting sites. Over the few last decades, several studies have been conducted to try to find solutions against insect decline and to preserve biodiversity. In the present …
