Disegni botanici di Angelina Damiani Lanza (1879 - 1936)
No full textBotanical drawings of Angelina Damiani Lanza (1879 - 1936). The drawings of Sicilian plants made by Ange- lina Damiani are reported and commented. After a brief presentation of the author’s personality, the technique used in the drawings is examined, together with the relevant value from the artistic and botanical point of view. This material, mainly consisting of pencil drawings gathered in an album recently donated to the Director of the Palermo Botanical Garden, sin- ce 2006 is exhibited in the small historical museum set up in one of the halls of the monumental Gymnasium of the same Botanical Garden. Most of the drawings done by Angelina Damiani for the studies of her husband, the Sicilian botanist Domenico Lanza, mainly concern various species and varieties of Calendula.This hard genus of the Asteraceae family was indeed covered by the special interest of Domenico Lanza, on which he carried out a valuable botanical monographic work
Reassembling Skins and Bones: Indigenous Posthumanism in Linda Hogan’s Solar Storms
No full textWhile posthumanism has contributed to questioning the foundations of humanism and the consequent process of exclusion it engendered of all those diverging from the universal category of ‘Man,’ numerous scholars have criticized this diverse philosophical movement from Indigenous perspectives. Multiple critics suggest a tendency within posthumanist strands of thought to oppose dualistic approaches presenting them as universal without considering the preexisting non-dualistic frameworks articulated by Indigenous scholars, while also appropriating Indigenous epistemes without acknowledging them, running the risk of becoming complicit with colonial violence and with what Rauna Kuokkanen has defined ‘epistemic ignorance.’ For this reason, projects of decolonizing posthumanist scholarship entail engaging and establishing a dialogue with Indigenous studies, fostering a ‘multiepistemic literacy.’ Acknowledging the productive potential of an alliance between Indigenous and posthumanist discourses in reorienting the conversation toward issues of settler colonialism, land sovereignty and Indigenous self-determination, this paper aims to apply an Indigenous posthumanist perspective to Chickasaw author Linda Hogan’s Solar Storms. In particular, the paper will focus, on the one hand, on representations within the novel of taxidermic practices, deeply tied to colonial violence, that transform animals into posthuman commodified objects, and, on the other, on instances of reassembling skins and bones in acts of regenerative creation, which, unlike taxidermy, acknowledge the need for reciprocity and processes of relational becoming. These new combinations of matter constitute on the part of the protagonist a way of envisioning new modes of being human, relating to the more-than-human, and affirming Indigenous self-determination

The plant landscape of the Sicilian archaeological areas through the iconographic documentation of travellers and naturalists
No full textThe landscape is commonly defined as the set of physical and historical-anthropological characters
expressed by a territory. Our re-elaboration defines the landscape as the set of perceivable characters
of a territory expressed in relation to the stratification of the occurred natural and cultural processes.
The Grand Tour reports are one of the most effective means to fix at least one stage of evolution from
the Sicilian landscape, before its further transformation. These reports provide often a stereotypical
image of the landscape of the Island, in particular as regards the major archaeological areas subjected
to particular attention by the cultured travellers.
The authors summarize the characters of the plant landscape of the main Sicilian archaeological
areas, through the analysis of both the rich documentation handed down by travellers, in particular
of the Grand Tour, and the descriptions of some naturalists who visited the region, between the second
half of the 18th and the whole 19th century portraying and /or describing the most expressive
places of its classicism.
In the landscape of these areas, the ruins are almost always framed by men in transit or in front of
the archaeological remains or in the surrounding area dedicated to the livestock care, with sparse trees
and bushes, sometimes constituted by exotic elements very incisive for the travellers,in majority
European from across the Alps; being unknown in the travellers’countriesthey represented very attractive
subjects. In fact, Opuntia ficus-indica, Agave americana and the historicized Phoenix dactylifera
are frequent. Among the indigenous elements we can recognize Olea europaea, Ceratonia siliqua,
Ficus carica and other species of leafy trees, partly survived and still present on the margins of the
ancient temples and theatres. Among these there would be Celtis australis, Fraxinus ornus, Quercus
ilex, Ulmus canescens. In the archaeological landscapes of the time, pines and cypresses are missing:
these trees were already introduced and widespread in Italy in Roman times but they appeared around
the Sicilian archaeological areas starting from the late nineteenth century.
The subject of this demonstration is presented by relating some photographic images of the places –
obviously later - beginning with the Alinari Archive (end of the 800s beginning of the 20th century),
with reproductions of iconographic documents by J.P.L.L. Houel (1782-87), P. Brydone (1806), R.
Saint-Non (1785), J.W. Goethe (1787) and other travellers (J.F. D'Ostervald, 1822-24; D.-D. Farjasse,
1835; C. A. Schneegans, 1890 and G. Vuillier, 1893). In this path of great utility was the reading of the
travel diaries of some naturalists, in particular C.S. Rafinesque Schmaltz (1810) and K. Presl (1817)

No full textPalisaded myofibroblastoma of the breast: a tumor closely mimicking schwannoma: report of 2 cases.
No full textMyofibroblastoma is a relatively rare, benign mesenchymal tumor that typically occurs in the breast parenchyma. Unlike mammary-type myofibroblastoma, myofibroblastoma that primarily arises in the lymph nodes exhibits nuclear palisading, and the term palisaded myofibroblastoma has been proposed, accordingly. We report 2 unusual cases of myofibroblastoma of the male breast, which showed a predominant (>90% of the entire tumor) nuclear palisading and Verocay-like bodies. The present cases represent a hitherto unreported variant of mammary-type myofibroblastoma closely mimicking schwannoma. The diagnosis of myofibroblastoma was supported by immunohistochemical analyses showing a diffuse staining for desmin and CD34. In addition, the diagnosis of myofibroblastoma was confirmed in 1 case cytogenetically by the demonstration of the monoallelic loss of the FOXO1/13q14 locus by fluorescence in situ hybridization. Pathologists should be aware of this unusual variant of mammary myofibroblastoma to assure a correct diagnosis
Methicillin-resistant Staphylococcus aureus (MRSA) is associated with low within-herd prevalence of intra-mammary infections in dairy cows : genotyping of isolates
No full textStaphylococcus aureus is one of the most common mastitis-causing pathogens worldwide. In the last decade, livestock-associated methicillin-resistant S. aureus (LA-MRSA) infections have been described in several species, included the bovines. Hence, this paper investigates the diffusion of MRSA within Italian dairy herds; the strains were further characterized using a DNA microarray, which detects 330 different sequences, including the methicillin-resistance genes mecA and mecC and SCC. mec typing. The analysis of overall patterns allows the assignment to Clonal Complexes (CC). Overall 163 S. aureus isolates, collected from quarter milk samples in 61 herds, were tested. MRSA strains were further processed using spa typing. Fifteen strains (9.2%), isolated in 9 herds (14.75%), carried mecA, but none harboured mecC. MRSA detection was significantly associated (. P<. 0.011) with a within-herd prevalence of S. aureus intra-mammary infections (IMI) ≤5%. Ten MRSA strains were assigned to CC398, the remaining ones to CC97 (. n=. 2), CC1 (. n=. 2) or CC8 (. n=. 1). In 3 herds, MRSA and MSSA co-existed: CC97-MRSA with CC398-MSSA, CC1-MRSA with CC8-MSSA and CC398-MRSA with CC126-MSSA. The results of spa typing showed an overall similar profile of the strains belonging to the same CC: t127-CC1, t1730-CC97, t899 in 8 out of 10 CC398. In the remaining 2 isolates a new spa type, t14644, was identified. The single CC8 was a t3092. The SCC. mec cassettes were classified as type IV, type V or type IV/V composite. All or most strains harboured the genes encoding the β-lactamase operon and the tetracycline resistance. Streptogramin resistance gene was related to CC398. Enterotoxin and leukocidin genes were carried only by CC1, CC8 and CC97-MRSA. The persistence of MRSA clones characterized by broader host range, in epidemiologically unrelated areas and in dairy herds with low prevalence of S. aureus IMI, might enhance the risk for adaptation to human species
