Effects of ozone on the foliar histology of the mastic plant (Pistacia lentiscus L.)
2004
[EN] An open-top chamber study was conducted to investigate the tissue and cellular-level foliar effects of ozone (O-3) on a Mediterranean evergreen species, the mastic plant (Pistacia lentiscus L.). Plants were exposed at three different O-3 levels, and leaf samples were collected periodically from the beginning of the exposure. Although no visible foliar injury was evident, alterations of the plastids and vacuoles in the mesophyll were observed. Senescence processes were accelerated with an anomalous stacking of tannin vacuoles, and a reduction in the size and number of the chloroplasts. Overall, most of the modifications induced by O-3 were consistent with previously reported observation…

Going, Returning, Rising. The Movement of the Organs in the Mesopotamian Anatomy
2019
Although many assyriological studies have been done on internal organs in the Mesopotamian worldview, the pathologies associated with them, and their metaphorical and ideological value, little attention have been paid to the fact that, sometimes, internal organs are associated with verbs of movement. Perhaps, this limited regard can be attributed to the assyriological look at the Mesopotamian body being shaped by the modern biomedicine. According to biomedicine, in fact, the human internal anatomy is composed of a series of organs which stay fixed in their positions. On the contrary, I want to show how the internal organs in Mesopotamian anatomy are thought as capable to move. I will demons…
La collezione di Anatomia Patologica dell'Università di Palermo: storia e consistenza al 1859.
2012
This paper outlines the history of the Cabinet of Pathological Anathomy at the University of Palermo, describes rapidly its current status and analyzes the composition of its displays in 1859. It aims to highlight the analogies with other collections of a similar kind and to pinpoint potential actions to endorse and develop this important scientific asset.
TRA ORRORE E SCIENZA: LA NASCITA DEL GABINETTO DI ANATOMIA PATOLOGICA DELL'UNIVERSITÀ' DI PALERMO

Un extraño nombre de la vena yugular interna: yugular ciega
1997
A misprint originated in the first work of human anatomy written in Persian, Tashrih-i Mansuri, where the internal jugular (widach âçwar), is misnamed blind jugular, is the starting point of the remembrance of the names given to this vein throughout the centuries and gives forth some commentaries related with the need to consult many original documents when identifying a name in a manuscript.
“Ehrlich färbt am längsten”. Sichtbarmachung bei Paul Ehrlich
2013
"Staining is the Best Policy". Visualization in the work of Paul Ehrlich. For nearly all of his life, the biomedical scientist Paul Ehrlich dedicated himself to work on dyes and staining at the interface between so-called color-chemistry and histopathology. The article begins by sketching out the field of histopathology at the junction of pathological anatomy, microtechniques, and the development of chemical dyes in the early 1870s when Ehrlich began his training as a medical student. The article explores Ehrlich's work staining first tissue and blood, and then pathogens and vital staining in the 1880s. In the late 1880s and 1890s, Ehrlich experimented with dyes as therapeutic agents. Stain…
Surgery of the Cranio-Vertebral Junction: Image Guidance, Navigation, and Augmented Reality
2019
Due to the density of essential, small, and mobile structures, mastering the surgical anatomy of the craniovertebral junction may be extremely challenging. Quality and safety of interventions can be improved using navigation. Currently, patient-specific anatomy preparation, surgical planning, intervention, and quality assessment are disconnected actions performed in different conditions and environments and by multiple team members. The whole process needs to be integrated by surgeons performing the intervention. The complexity of the process exposes to errors and degraded precision. It is therefore relevant to develop tools that reduce the need to extrapolate and simplify the information i…
Microgravity-induced alterations in signal transduction in cells of the immune system
2010
Since decades it is known that the activity of cells of the immune system is severely dysregulated in microgravity, however, the underlying molecular aspects have not been elucidated yet. The identification of gravity-sensitive molecular mechanisms in cells of the immune system is an important and indispensable prerequisite for the development of counteractive measures to prevent or treat disturbed immune cell function of astronauts during long-term space missions. Moreover, their sensitivity to altered gravity renders immune cells an ideal model system to understand if and how gravity on Earth is required for normal mammalian cell function and signal transduction. We investigated the effec…
Perlecan Maintains microvessel integrity in vivo and modulates their formation in vitro
2012
Perlecan is a heparan sulfate proteoglycan assembled into the vascular basement membranes (BMs) during vasculogenesis. In the present study we have investigated vessel formation in mice, teratomas and embryoid bodies (EBs) in the absence of perlecan. We found that perlecan was dispensable for blood vessel formation and maturation until embryonic day (E) 12.5. At later stages of development 40% of mutant embryos showed dilated microvessels in brain and skin, which ruptured and led to severe bleedings. Surprisingly, teratomas derived from perlecan-null ES cells showed efficient contribution of perlecan-deficient endothelial cells to an apparently normal tumor vasculature. However, in perlecan…
