Extracellular space and electrolyte distribution in cortex and white matter of dog brain in cold induced oedema
1973
24 hours after a circumscribed cold injury of the cortex dog brains were perfused from the lateral ventricle and the frontal subarachnoidal space to the cisterna magna with an artificial CSF containing trace amounts of35S-labelled thiosulphate. Simultaneously the extracellular tracer was administered intravenously. Extracellular fluid volume was estimated and found to be increased from 10 to 15% in the oedematous cortex and from 10 to 27% in the oedematous white matter. The actual size of ECS in oedematous white matter, however, must be larger as indicated by the relative alterations of thiosulphate distribution, tissue water, sodium and chloride. Apparently a small part of the fluid accumu…
Exploring the Virchow-Robin spaces function: A unified theory of brain diseases.
2016
Background: Cerebrospinal fluid (CSF) transport across the central nervous system (CNS) is no longer believed to be on the conventional lines. The Virchow-Robin space (VRS) that facilitates CSF transport from the basal cisterns into the brain interstitial fluid (ISF) has gained interest in a whole new array of studies. Moreover, new line of evidence suggests that VRS may be involved in different pathological mechanisms of brain diseases. Methods: Here, we review emerging studies proving the feasible role of VRS in sleep, Alzheimer's disease, chronic traumatic encephalopathy, and traumatic brain injury (TBI). Results: In this study, we have outlined the possible role of VRS in different path…
Cerebral Oxygen Supply in Brain Edema and During Ventriculo-Cisternal Perfusion
1976
Numerous brain injuries and brain tumors lead to edema in brain tissue which can have consequences for the oxygen supply to the damaged tissue as well as to adjacent tissue areas. In studies made of the blood flow and oxygen supply in perifocal edematous tissue of brain tumors and lesions in patients undergoing various brain operations a direct relationship between the regional blood flow and the water content could be demonstrated (3). As the water content of the tissue increased, the blood flow through it diminished. In many cases, the reduction of the blood flow in the brain tissue induced an insufficient oxygen supply. In the tissue samples under investigation, the CrP and ATP concentra…
Characterization of mortars from ancient and traditional water supply systems in Sicily
2008
Long aged mortars from ancient hydraulic constructions of Sicily, i.e. the Roman aqueduct of Thermae and the Punic cisterns and traditional water supply systems in Pantelleria, have been characterised by means of XRD analysis, optical microscopy and simultaneous thermal analysis to correlate the hydraulic properties to the texture and to their different role in the construction, i.e. lining, covering, roofing and joint mortars. According to a procedure proposed in the literature all of the samples, but two air hardening ones, show high hydraulicity, which somehow can be related to the characteristics of aggregates.
Riscoperta di alcuni ipogei artificiali nel Comune di Sutera (Caltanissetta, Sicilia centrale)
2020
Grazie ad approfondite ricerche di archivio e accurate indagini speleologiche, sono stati ispezionati e documentati diversi ipogei artificiali presenti nel comprensorio di Sutera (CL). L’area di Sutera, caratterizzata da affioramenti evaporitici messiniani e non lontana da importanti miniere di salgemma e di zolfo, ha subito una veloce corsa verso la ricerca di minerali pregiati intorno ai primi del ‘900. A memoria di queste attività sono rimaste diverse tipologie di cavità, quali: gallerie di carreggio, discenderie per ricerca mineraria, ma anche antiche cisterne per la raccolta d’acqua dove recentemente, a seguito di operazioni di ripristino e pulizia, sono stati effettuati importanti rit…
Gestione e uso dell’acqua a Solunto: le cisterne
2019
The paper presents the first issues of a new study about cisterns of Solunto, carthaginese city situated in Sicily, and water management of the town during the graeco-roman period. It shows the ways of collecting and managing water, particularly in what concerns raining water. XIXth et XXth century excavations have discovered many hydraulic structures, generally cisterns (70 for the moment with a capacity between 10 and 30 m3) and channels or architectonic elements which have never been studied. We begin with a general presentation and continue with some peculiar structures of the Solunto environment.
12 dicembre 1942. Bombe su Solunto. Storia di un fatto dimenticato
2022
This contribution presents the traces on the ground and the archive documentation of a bombardment that took place in Solunto the night of 12 December 1942. The starting point of this research was a photograph preserved in the archives of the Regional Archaeological Museum Antonio Salinas which documents the restoration of a Solunto cistern following the bombing of the Allies. The site, in fact, was hit by a bomb which caused damage to the large masonry cistern placed near the Casa delle Maschere, at the highest point of the site. Archive research has allowed us to reconstruct the dynamics of the facts and revealed the commitment of the Superintendents to the Antiquities of Western Sicily, …
Cisternostomy for Traumatic Brain Injury: A New Era Begins
2016
Traumatic brain injury (TBI) is a major cause of death and disability especially in the young generations. In the United States TBI affects about 1.7 million people annually [1] and this number is higher in the developing countries. It is well known that TBI is associated to a primary and secondary brain injury. The first is without solution and depends on the impact. In surviving patients, what plays a critical role is the subsequent secondary injury since, without effective treatments, complex cascades will promote additional brain damage.
La gestione delle acque nelle città fenicio-puniche della Sicilia: riflessioni e prospettive a partire dalle evidenze di Mozia, Solunto e Palermo
2017
The study of the hydraulic preparations of Phoenician-Punic Sicily constitutes a field of investigation alas problematic, especially with regard to the evidence related to the archaic-classical period. Not we know, for example, hydraulic works of a certain engineering commitment comparable to the oldest aqueducts of Tyre known from the sources 2 or the great Greek hydraulic infrastructures of the archaic era 3. The problem of water management in Sicily has, in recent years, received a considerable pulso and concerned especially the evidence of the Greek colonial foundation4 cities. Such "abundance" of data is not yet appreciable for Phoenician foundations, except, as we shall see, of Motya,…
Le cisterne del castello di Butera: risultati delle indagini archeologiche
2014
In this work are presented the excavation’s results of the cisterns of the Medieval Castle of Butera. The study of pottery and other objects retrieved in the cisterns and the study of the stratigraphic relationships with the walls which are above the cisterns, permit to establish when the cisterns were filled and permit a better definition oh the life’s phases of the court and of the Castle, involved in destructions and reconstructions during Medieval e post-medieval ages
