Steady-state levels of retinal 24S-hydroxycholesterol are maintained by glial cells intervention after elevation of intraocular pressure in the rat

2012

Purpose: Our previous studies suggested that CYP46A1 and 24S-hydroxycholesterol. (24SOH) may be associated with glaucoma. Loss of CYP46A1-expressing retinal. ganglion cells is involved in the activation of glia, and therefore possibly in the. disbalance of cholesterol. In this context, the purpose of our present work was to. emphasize the glial and longitudinal CYP46A1 expression after an interventional. glaucoma-related stress triggered by elevated intraocular pressure (IOP). Methods: Sprague–Dawley rats were submitted to laser photocoagulation of the. trabecular meshwork, limbus and episcleral veins in one eye to induce elevated IOP. Rats were euthanized at days 3, 14, 30 and 60 (n = 10 p…

Traductions, transformations, transmutations du Pygmalion de Rousseau dans les royaumes de Naples et de Sicile

2017

The Rousseau’s Melodrama, Pygmalion, first time staged in 1771 at Lyon, arrived in Naples in 1773 performed in French by a French theatrical company and with the music composed by Aspelmayr. At the same time in the kingdom of Naples, like in northern Italy and in Austria, the first Italian translations and the first attempt to change the original text in an Opera libretto put essential questions about the translation of theatrical texts and especially the change of a dramatic-musical form, a semiotic transmutation. In 1797, in Palermo, according to the historian Pitrè, was staged a Pigmalione or Pigmaglione translated perhaps by Sografi, transmuted in operatic form, put in music by Asioli o…

Jaume ultimo conte di Urgell: eco di una ribellione nella documentazione siciliana

2020

Scomparso il 31 maggio 1410 Martino l’Umano senza discendenti legittimi diretti, si pose il problema di eleggere un nuovo sovrano per la Corona d’Aragona. Il numero inizialmente cospicuo di candidati al trono si ridusse a due: l’infante di Castiglia Ferdinando di Trastámara e il conte Jaume de Urgell, in linea teorica il pretendente più accreditato. A diventare re fu invece Ferdinando, elezione che fu vista nell’isola come fine dei disordini locali. La notizia della cattura del conte di Urgell fu presto nota ai siciliani, come attesta un gruppo di lettere contenute nella documentazione cittadina. Il saggio ricostruisce la complessa vicenda politica e umana del ribelle Jaume, destinato a una…

Solitary keratoacanthoma involving upper lip: a diagnostic dilemma - case report and a brief review

2010

Keratoacanthoma (KA) is a benign epithelial proliferative lesion which frequently occurs on the sun exposed areas of the skin. KA originates within the pilosebaceous apparatus of the skin and may be solitary or multiple. Solitary KA can be difficult to differentiate from squamous cell carcinoma (SCC) both clinically and microscopically. However, the clinical course of the lesion and its ability to self involute makes it a distinct clinical entity. Solitary KA appears on the vermilion border of the lower lips with some frequency. A case of keratoacanthoma involving the upper lip is reported presenting as an exophytic growth that resolved after excisional biopsy. Photo- graphic documentation …

Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment

2015

DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…

Biological Responses of <I>Rhynchophorus ferrugineus</I> (Coleoptera: Curculionidae) to <I>Steinernema carpocapsae</I> (Nemat…

2013

Rhynchophorus ferrugineus (Olivier 1790) (Coleoptera: Curculionidae) is becoming a serious problem in Mediterranean areas where it is well-adapted, and now is present even in the United States (California). The infestations are primarily in urban areas where chemical control is not advisable and million of Euros are spent to control it. The effects of the entomopathogenic nematode Steinernema carpocapsae (Nematoda: Steinernematidae) on mortality, growth, as well as the immune activity of R. ferrugineus larvae, were investigated. R. ferrugineus mortality exhibited a positive trend with the dosage and duration of exposure to S. carpocapsae. The median lethal dose and median lethal time, impor…

The culturable bacterial community of frass produced by larvae of Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) in the Canary island …

2012

Aims:  Larvae of the red palm weevil (RPW) Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) feed inside palm stem tissues, making galleries and producing a wet fermenting frass. We characterized the culturable bacteria associated with frass produced by tunnelling larvae inside the Canary island date palms and investigated the role of frass and gut bacteria in plant polymers breakdown. Methods and Results:  A culture-dependent method was used to isolate bacteria from frass and noninfested palm tissues. Bacterial isolates were grouped into operational taxonomic units based on polymorphisms in the ITS-PCR profiles, and representative isolates were identified by partial sequencing …

One Species, Hundreds of Subspecies? New Insight into the Intraspecific Classification of the Old World Swallowtail (Papilio machaon Linnaeus , 1758)…

2022

The Old World swallowtail Papilio machaon Linnaeus, 1758 is one of the most well-known and most characteristic members of the family Papilionidae. Over the past two centuries, the butterfly has been the subject of many studies. P. machaon is characterised by a tendency to change the wing colour pattern. In turn, due to the great interest of collectors and amateur entomologists, these studies have been converted into the description of over 100 colour forms, aberrations and subspecies. In this study, mitochondrial DNA (mtDNA), 16S rDNA and cytochrome b sequences were used to examine the correlation between the intraspecific classification and genetic structure of P. machaon. The study used 8…

Anisotropic elliptic equations with gradient-dependent lower order terms and L^1 data

2023

<abstract><p>We prove the existence of a weak solution for a general class of Dirichlet anisotropic elliptic problems such as $ \mathcal Au+\Phi(x, u, \nabla u) = \mathfrak{B}u+f $ in $ \Omega $, where $ \Omega $ is a bounded open subset of $ \mathbb R^N $ and $ f\in L^1(\Omega) $ is arbitrary. The principal part is a divergence-form nonlinear anisotropic operator $ \mathcal A $, the prototype of which is $ \mathcal A u = -\sum_{j = 1}^N \partial_j(|\partial_j u|^{p_j-2}\partial_j u) $ with $ p_j > 1 $ for all $ 1\leq j\leq N $ and $ \sum_{j = 1}^N (1/p_j) > 1 $. As a novelty in this paper, our lower order terms involve a new class of operators $ \mathfrak B $ such…
