La progettazione di nuovi spazi educativi per l’infanzia: da Ellen Key a Maria Montessori

Tiziana Pironi
The essay presents a comparison between the thought of Ellen Key and that of Maria Montessori. Changes that involved the role of women, caught in its interdependence with the development of new educational practices, were the center of the theoretical contribution of Ellen Key. Maria Montessori believed that only women work outside the home would guarantee the economic independence necessary to form a union on sentiment rather than on utilitarian calculations and therefore she did...

Induction of altered cellular response to oxidative stress in HT29 colon cancer cells treated with Metformin

Alberto Smargiassi, Stefano Mancini, Francesco Cavani, Marta Benincasa, Luca Roncucci & Paola Sena
Accumulating evidences suggest that Metformin, a biguanide class of anti-diabet- ic drugs, possesses anti-cancer properties (1). In a number of preclinical and clinical studies, Metformin reduced proliferation, induced apoptosis, caused cell cycle arrest, and reduced incidence and growth of tumors (2). HT-29 is a human colorectal ade- nocarcinoma cell line with epithelial morphology and represents a xenograft tumor model for colorectal cancer. Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that controls the...

Osteonic organization of limb bones in mammals, including humans, and birds: a preliminary study

Paola Castrogiovanni, Rosa Imbesi, Marco Fisichella & Venera Mazzone
As it is well known, bone tissue is characterized by a calcified extracellular matrix which makes this tissue suitable to support the body and protect the inner organs. Lamellar bone tissue is organized in lamellae, 3-7 µm in thickness, and arranged concentrically around vascular channels: the basic structure in this type of organization is called Haversian system or osteon and the diameter of osteons depends on the number of lamellae. Shape and regional density of...

Conservazione dell’architettura funeraria etrusca. Il caso dell’ipogeo di marciana scavato nel granito

Giuseppe Centauro, Carlo Garzonio & Michelangelo Zecchini
The problematic nature of Etruscan funerary architecture conservation due to the peculiar environmental conditions consisting of underground positions with flows of visitors represents a typical aim of the archaeological restoration The study case should be considered as emblematic for the iconographic relevance of the gentilitial etruscan tomb, of late orientalizing or archaic age, and for the particular physical nature of the hypogeum which is entirely excavated in a granodiorite rockmass in the center of Marciana...

The Monastery of Bir el-Hamam, Mount Gerizim, Palestine. Site Management and Presentation

Hamdan Taha
The archaeological site of Bir el-Hamam, located on the northern top of Mt Gerizim, Nablus, in Palestine was discovered in 2001 during preparatory work for the construction of the ‘House of Palestine, a rotunda style residence for Mr. Munib al-Masri. In that same year, a salvage excavation was carried out by the Department of Antiquities and Cultural Heritage of the Ministry of Tourism and Antiquities, and staff and students from An-Najah National University, directed by...

Updated distribution of hybrids between Lissotriton vulgaris and Lissotriton montandoni (Amphibia: Caudata: Salamandridae) in Romania

Iulian Gherghel, Alexandru Strugariu, Ioana-Madalina Ambrosă & Ștefan Zamfirescu
Lissotriton montandoni is an endemic newt species found only in the Carpathian Mountains and lives in sympatry with Lissotriton vulgaris in many aquatic habitats from the entire range of the former species in the Carpathian and Sudetes Mountains or in the hilly areas from the Subcarpathians. These two species usually generate hybrids where their parapatric ranges meet, especially along rivers that flow from the inside of the Carpathians, where valleys are used as ecological corridors...

Is the exploratory behavior of Liolaemus nitidus modulated by sex?

Jaime Troncoso-Palacios & Antonieta Labra
Chemoreception is an important sensory modality used by lizards to assess their environments and to communicate. However, despite growing information regarding chemoreception in this taxon, its modulation by sex has been little explored, except in researches directly focused on reproductive aspects. In this study, we compared the responses of females and males of the Iguanid lizard Liolaemus nitidus to scents from conspecifics of the same sex, themselves (own), a predator, and a control. The only...

Skeletal development and adult osteology of Hypsiboas pulchellus (Anura: Hylidae)

Julio Hoyos, Marcelo Sánchez-Villagra, Alfredo Carlini & Christian Mitgutsch
Osteological and skeletal characters have long been proven to be particularly informative in taxonomic and systematic research. Furthermore, ossification sequences are assumed to be a potential tool to investigate developmental states and developmental modes of fossil and extant skeletal specimens. Herein, we provide a detailed account on adult osteology and skeletogenesis in the Montevideo treefrog, Hypsiboas pulchellus (Anura: Hylidae) based on evaluation of a series of cleared and stained specimens. A consensus sequence of ossification,...

Genetic variability of Mesalina watsonana (Reptilia: Lacertidae) on the Iranian plateau and its phylogenetic and biogeographic affinities as inferred from mtDNA sequences

Jiri Smid & Daniel Frynta
The lacertid lizard Mesalina watsonana is widely distributed on the Iranian plateau where it is one of the most common lizards. However, the intraspecific variability and the phylogenetic position of this species within the genus still remain unknown. We sequenced a 715bp long fragment of the mtDNA cytochrome b gene from lizards sampled in 10 localities covering the Iranian distribution range of the species. We identified four distinct and geographically isolated clades with an average...

Eryx jaculus (Reptilia, Boidae) north of Danube: a road-killed specimen from Romania

Severus Covaciu-Marcov, Sára Ferenți, Alfred Cicort-Lucaciu & István Sas
In September 2011 we identified a killed specimen of Eryx jaculus on the road between the towns of Turnu Măgurele and Corabia, in southern Romania. This seems to be the first record of the species north of the Danube. Although surprising, the identification of E. jaculus in the area is interpreted in the light of the presence of other species of herpetofauna in the Danube floodplain with similar ecological requirements, reaching here their northern distribution...

Habitat selection of two sympatric species of Ameiva in East Costa Rica

Esther Sebastián-González & Ramón Gómez
Identifying the differences in habitat use for sympatric species is important for understanding the species preferences and the limits of population distribution. We studied the differences in the habitat use of two understudied sympatric species of Ameiva (A. festiva and A. quadrilineata) in a natural reserve of the Caribbean coast of Coast Rica. Ameiva quadrilineata showed a more restrictive habitat use pattern than A. festiva. A. quadrilineata’s smaller body size may be one of the...

Does acclimation at higher temperatures affect the locomotor performance of one of the southernmost reptiles in the world?

Jimena Fernández & Nora Ibargüengoytía
When an animal in the laboratory experiences a change in temperature, physiological processes are affected but they stabilize under the new temperature condition over a few weeks by a process of phenotypic plasticity called acclimation, but whether an organism can acclimate or not depends on the trait and the taxon. Liolaemus sarmientoi is one of the southernmost reptiles in the world, inhabiting the extreme and arid environment of Patagonia, Argentina, characterised by great seasonal climatic...

Reproductive strategy of male and female eastern spiny lizards Sceloporus spinosus (Squamata: Phrynosomatidae) from a region of the Chihuahuan Desert, México

Aurelio Ramirez-Bautista, Barry Stephenson, Xóchitl Hernández-Ibarra, Uriel Hernández-Salinas, Raciel Cruz-Elizalde, Abraham Lozano & Geoffrey Smith
We examined the reproductive strategy of male (n = 84) and female (n = 62) S. spinosus from a single population in San Luis Potosí, México. The male reproductive cycle peaked in March and April and declined from May to September, and was not correlated with fat body mass, but was positively correlated with liver mass. The female reproductive cycle peaked in April and May and declined from June through November, and was not correlated...

Chemical skin defence in the Eastern fire-bellied toad Bombina orientalis: an ultrastructural approach to the mechanism of poison gland rehabilitation after discharge

Sara Quagliata, Cecilia Malentacchi, Filippo Giachi & Giovanni Delfino
Type I serous glands in the skin of the Eastern yellow-bellied toad Bombina orientalis released their product massively after 10-3 M nor-adrenalin (NA) stimulation, mimicking orthosympathetic control on poison emission in chemical skin defence. Features of cutaneous glands involved in this bulk discharge were observed under light and electron microscopes. Furthermore, restoration of depleted glands was followed after 1, 2 and 3 weeks, and compared with serous biosynthesis during larval gland development. Bulk discharge was...

Road mortality threatens small northern populations of the European pond turtle, Emys orbicularis

Giedrius Trakimas & Jonas Sidaravičius
Little is known about road mortality and the effects to European pond turtle Emys orbicularis populations at the northern border of its range. Survival of the turtle populations in suboptimal conditions depends heavily on longevity, regular annual breeding and relatively large clutch sizes, but additional unnatural mortality could alter their survival rates. Loss of only single turtle in majority of northern populations could mean a loss of 3-20% of subpopulation. But due to comparative rarity...

Unexpected phylogeographic affinities of Psammodromus algirus from Conigli islet (Lampedusa)

Miguel A. Carretero, Anna Perera, Pietro Lo Cascio, Claudia Corti & D. James Harris
The only Italian population of the lacertid Psammodromus algirus is found in Conigli islet whereas the species is absent from the nearby island of Lampedusa. The phylogeographic relationships of this population were investigated. Mitochondrial DNA (12S rRNA and 16S rRNA) fragment sequences were analysed and compared with already published sequences from the whole species range. In all the analyses, the sample from Conigli grouped with those from Morocco and not with the closer Tunisian ones....
