Evaluation of Chemical Composition of Essential Oils Derived from Different Pelargonium Species Leaves
2019
Plants have been used for their aromatic and medicinal purposes for centuries. The genus Pelargonium contains about 250-280 species and cultivated around the world for the production of essential oils and absolutes. Pelargonium species are remarkable for their odour diversity, from fresh, lemon and minty scent, through floral, rose, fruity up to spicy and camphoreous smell as well as many health beneficial properties, that is why their essential oils are widely used in perfume, cosmetic, food and pharmaceutical industries. The aim of this study was to determine variability in populations of Pelargonium genus by evaluating their differences in quantitative and qualitative essential oils comp…
The use of leaves of Rosmarinus officinalis L. as samplers for polycyclic aromatic hydrocarbons. Assessment of air quality in the area of Palermo
2002
The quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) in vegetables and animals allows us to evaluate the quality of air, in a determined geographic area, without the need of making long samplers with complicate instrumentation. In this work, Rosmarinus officinalis leaves have been used as passive samplers. In particular, this plant was chosen because it is widespread in the Mediterranean area and it is commonly found both in the metropolitan and in the peripheral areas of the city of Palermo. Results for the concentration of total polycyclic aromatic hydrocarbons (the sum of the 22 compounds) and the PAHs distribution in leaves from Rosmarinus officinalis are presented. Puri…
Fonti documentarie per le cappelle di Santa Rosalia in Monte Pellegrino e nella Cattedrale di Palermo
2010
L’epidemia di peste scoppiata all’inizio del 1624 e il successivo ritrovamento “miracoloso” delle spoglie di S. Rosalia, a cui fu attribuito il merito della sconfitta del “terribile morbo”, indussero il Senato di Palermo a promuovere la sistemazione della grotta sul monte Pellegrino, dove si riteneva fosse stata sepolta la santa, e la realizzazione di una sontuosa cappella marmorea all’interno della cattedrale, utilizzando il vano cupolato che introduceva alle cappelle di S. Cristina e S. Ninfa (forse in origine la quattrocentesca cappella di S. Cristina), creando così un unico accesso ai tre reliquari delle sante patrone; tale sistemazione non è più visibile, poiché fu poi smantellata in o…
Miguel del Prado, pintor de retablos en Valencia. Su fallecimiento en las Germanías (1521)
2017
Miguel del Prado, a painter who formed a company with Miguel Esteve in order to paint the now-lost Valencia town hall chapel in 1519, is an artist for whom there is scant documentary evidence. He has been identified with the anonymous Master of the Grifo, but this has been questioned recently. The author here offers news of a contract given to del Prado for an altarpiece in the Rosary Chapel of the old convent of Santo Domingo in Valencia that he was unable to fulfill due to his untimely death. It has been possible to certify that he perished on the battlefield of Almenara during the Germanias Revolt of 1521. Therefore the chronology for this painter has now been reduced by more than 16 yea…

Plexiform Atypical Spitz Tumor With Rosette-Like Giant Cells. A Histologic and Immunohistochemical Study on a Case Suggesting Ganglioneuroblastic Dif…
2018
Spitz nevi, atypical Spitz tumors and Spitzoid melanoma, the three clinicopathologic forms that constitute the spectrum of the Spitz-type melanocytic lesions, share a histologic picture characterized by large spindle and/or epithelioid ganglion-like cells, with various admixtures of multinucleate bizarre cells. This remarkable cytology has always been interpreted as an unusual, as well as unexplained form of atypia. We report a case of atypical Spitz tumor with Homer Wright-like rosettes, a feature characteristic of ganglioneuroblastic proliferation. Furthermore, the ganglion-like cells of the tumor showed basophilic punctuation in the cytoplasm, reminiscent of Nissl substance, and a few ce…
Rīta rosme kā intelektuālās darbības veicinātājs sākumskolā
2017
Diplomdarba “Rīta rosme kā intelektuālās darbības veicinātājs sākumskolā” mērķis ir noskaidrot rīta rosmes kā intelektuālās attīstības veicinātāja pozitīvos faktorus un izstrādāt rīta rosmes kompleksus dažādām vidēm. Darba pirmajā teorētiskajā daļā tiek pētīta sākumskolas bērnu fiziskā, psiholoģiskā un intelektuālā attīstība, kā arī analizētas šī vecumposma īpatnības mācību procesā un fiziskās aktivitātēs. Darba otrā teorētiskā daļa pievēršas rīta rosmes būtībai un tās pielietošanas iespējām mācību procesa ietvaros. Praktiskajā daļā pielietotās pētnieciskās metodes ir skolēnu un skolotāju aptauja, skolotāju strukturēta intervija, pedagoģiskā novērošana, izstrādāti un aprobēti rīta rosmes ko…
PELLEGRINO ROSSI RAPPORTEUR DU PROJET DE LOI RELATIF A LA CONSTITUTION POLITIQUE DES COLONIES FRANÇAISES
2018
On 12 June 1840, the lawyer and economist Pellegrino Rossi, Peer of France, entered the Commission chaired by Duke Victor de Broglie and in charge of an investigation of issues related to the slavery and the political constitution of the French colonies. This article aims to examine the role played by Pellegrino Rossi in the debate on the abolition of slavery in the French colonies and the project of political constitution of French colonies of which Rossi was the speaker and editor of the same articles.
Mechanism of action of Rhodiola, salidroside, tyrosol and triandrin in isolated neuroglial cells: An interactive pathway analysis of the downstream e…
2014
Abstract Aim The aim of this study was to identify the targets (genes, interactive signaling pathways, and molecular networks) of Rhodiola rosea extract in isolated neuroglia cells and to predict the effects of Rhodiola extract on cellular functions and diseases. In addition, the potential mechanism of action of Rhodiola rosea extract was elucidated, and the “active principle” among the three isolated constituents (salidroside, triandrin, and tyrosol) was identified. Methods Gene expression profiling was performed using the T98G human neuroglia cell line after treatment with the Rhodiola rosea SHR-5 extract and several of its individual constituents (salidroside, triandrin and tyrosol). An …
Diversity and distribution of feather lice on Greater Flamingoes (Phoenicopterus ruber roseus) in the Camargue, southern France
2002
Feather lice were collected from 2S0 chicks of the Greater Flamingo (Phoenicopterus ruber roseus Pallas) captured alive in the Camargue, southern France, in July 1997. Five louse species were identified: Colpocephalum heterosoma Piaget, Colpocephalum salimalii Clay and Trinoton femoratum Piaget of the family Menoponidae; Anaticola phoenicopteri (Coinde) and Anatoecus pygaspis (Nitzsch [in Giebel]) of the family Philopteridae. Our collecting results also show that there is body-site segregation among the several louse species inhabiting the same host individual.
