Parasorex depereti (Crochet, 1986) (Lipotyphla, Mammalia), from the Upper Messinian (MN13) fissure filling of Brisighella (Faenza, Northern Apennine, Italy)
No full textA large-sized species of Parasorex is rather common in the MN13 mammal assemblages from the uppermost Messinian sandy - marly fissure fillings within the Gessoso Solfifera Formation at Brisighella (Northern Apennine). This erinaceid had been originally classified as Galerix sp. in the first papers on the Brisighella fauna. Later on, it was described in detail in an unpublished dissertation by Fanfani (1999) who referred it to Galerix depereti. Unfortunately, the study remained virtually unknown to the scientific community. Hoek Ostende (2001) included G. depereti in the genus Parasorex, while Ziegler (2005) accommodated it in Schizogalerix. Hoek Ostende’s (2001) opinion is followed here. Parasorex deperetihas been described by Crochet (1986) on rather scarce material from a few Early Pliocene (MN14-15) localities of southern France and Spain. Parasorex cf. depereti is represented in the Italian Messinian/Zanclean deposits of Borro Strolla, (Val d’Elsa Basin, Tuscany) by a single M3 (Abbazzi et al,, 2008). Several other remains from the Early Pliocene fauna of Capo_Mannu (Mandriola, Sardinia) have been referred to Parasorex depereti (Furio and Angelone, 2011). The species seems actually distribute in south-western Europe, where it represents the youngest occurrence of genus Parasorex. The very abundant sample of P. depereti from fissure filling BRS25 enables a more accurate and comprehensive biometrical description of the species. It also permits to inspect the mesial traits of the dentition which Crochet (1986) had failed to describe. The systematic position of the species can also be revisited and compared with those of other European Galericini taxa. Abbazzi, L., Benvenuti, M., Ceci, M.

Apulogalerix pusillus nov. gen., nov. sp., the small-sized Galericinae (Erinaceidae, Mammalia) from the ‘‘Terre Rosse’’ fissure filling of the Gargano (Foggia, South-Eastern Italy)
No full textA small moonrat belonging to the Galericini tribe occurs in all the assemblages from the Terre Rosse
fissure fillings of the Gargano. It was first mentioned in the pioneering report of Freudenthal and by
Butler in his study of the ‘‘gigantic’’ Deinogalerix, and has been quoted with different names several times
in faunal lists of the Terre Rosse endemic faunas. Up to date, however, the description of this gymnure
has never been achieved. We present here the taxonomical and morphological description of a sample
from Fissure Filling F32 that is considered to document the youngest phase of population of the Gargano
Paleoarchipelago. The comparisons with genera Galerix, Parasorex and Schizogalerix, show that the
Gargano gymnure is well distinct from these three genera, and that it deserves a generic status. The small
Galericini is therefore referred to Apulogalerix pusillus nov. gen., nov. sp. The enlarged and swollen
premolar series, the small, pointed molars, some details in the morphology of the lower fourth premolar
and of the third upper premolar, indicate that Apulogalerix nov. gen. is an endemic taxon, likely derived
from a Parasorex ancestor, which specialized in a malacophagous diet
The Small Sized Galericini from F32 “Terre Rosse” fissure filling (Gargano, Southeastern Italy) and its biochronological implications.
Full text linkDeinogalerix is by far the better known Galericinae (Galericini according
toVan den Hoek Ostende, 2001) from the Gargano fissure filling thanks to very
careful description of Butler 1980. However, another moon rat, very small sized,
belonging to the Galericini tribe, is virtually present in all the assemblages from
the “terre rosse” fissure filling of the Gargano. It was first mentioned in the
pioneering report of Freudenthal (1971) and by Butler (1980) in his study of the
“gigantic” Deinogaleri and it has been quoted in several faunal lists. It has been
ascribed to Parasorex by Van den Hoek Ostende (2001), and to Galerix
(Apulogalerix) by Fanfani (1999). Van den Hoek Ostende (2001) considered it and
the large Deinogalerix as derived from a common ancestor. Up to date, however, a
detailed description of the characters of this gymnure has never been presented
to the scientific community. Indeed, only De Giuli et al. (1987) used the size of
the mandible in six selected samples to describe the variation along their
proposed biochonology of the terre rosse.
We present here the morphological description of a sample from Fissure
Filling F32, that is considered to represent the youngest phase of population of
the Gargano Paleoarchipelago. This sample has been chosen since it is very rich
and is not affected by taphonomic biases. The philogenetic relationships of the
Gargano Galericini are discussed. The description of a new very primitive species
of Deingalerix from Pirro 12 fissure filling (Villier, 2011) opens new perspectives
to investigate the relationships between the small and the gigantic Galericine of
the Gargano
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Endometrial cancer: magnetic resonance Imaging
No full textCarcinoma of the endometrium is the most common invasive gynecologic malignancy of the female genital tract. Clinically, patients with endometrial carcinoma present with abnormal uterine bleeding. The role of magnetic resonance imaging (MRI) in endometrial carcinoma is disease staging and treatment planning. MRI has been shown to be the most valuable imaging mod-ality in this task, compared with endovaginal ultrasound and computed tomography, because of its intrinsic contrast resolution and multiplanar capability. MRI protocol includes axial T1-weighted images; axial, sagittal, and coronal T2-weighted images; and dynamic gadolinium-enhanced T1-weighted imaging. MR examination is usually performed in the supine position with a phased array multicoil using a four-coil configuration. Endometrial carcinoma is isointense with the normal endometrium and myometrium on noncontrast T1-weighted images and has a variable appearance on T2-weighted images demonstrating heterogeneous signal intensity. The appearance of noninvasive endometrial carcinoma on MRI is characterized by a normal or thickened endometrium, with an intact junctional zone and a sharp tumor-myometrium interface. Invasive endometrial carcinoma is characterized disruption or irregularity of the junctional zone by intermediate signal intensity mass on T2-weighted images. Invasion of the cervical stroma is diagnosed when the low signal intensity cervical stroma is disrupted by the higher signal intensity endometrial carcinoma. MRI in endometrial carcinoma performs better than other imaging modalities in disease staging and treatment planning. Further, the accuracy and the cost of MRI are equivalent to those of surgical staging
