New Osteological Data on Malaria in Sardinia from Antiquity to the Modern Era  [PDF]
Eugenia Tognotti, Andrea Montella, Peter J. Brown, Pasquale Bandiera
Advances in Infectious Diseases (AID) , 2017, DOI: 10.4236/aid.2017.72005
Abstract: Malaria has been an important disease throughout the history, particularly in the Mediterranean. The island of Sardinia (Italy) was characterized by severe endemic malaria from antiquity until its eradication in 1950. It provides an exceptional and unique site to examine the history of the disease and its effects on human biology and ecology. Endemic malaria can cause chronic hemolytic anemias that may result in osteological signatures. This paper examines these markers, Porotic Hyperostosis (PH) and Cribra Orbitalia (CO), which are identified from skeletons uncovered in archaeological excavations in Northern Sardinia. Previous hypotheses based on historical references and genetic data suggest that the disease was absent on the island in prehistory and was imported, probably by slaves, during the Carthaginian period (6th to 3rd century BC). This article reports on the paleontological analysis of 283 skeletons excavated from seven archeological sites dating from 4700 BP to 1582 AD. Osteological remains were examined for markers CO and PH as a proxy variable for malaria. The findings support previous hypotheses about history of malaria over time.

Further studies on the marine tardigrade fauna from Sardinia (Italy)
Rossana D'ADDABBO,Maria GALLO,Cristiana DE LEONARDIS,Roberto SANDULLI
Journal of Limnology , 2007, DOI: 10.4081/jlimnol.2007.s1.56
Abstract: An investigation on the taxonomy and ecology of marine tardigrades was carried out in different intertidal and subtidal sites along the coasts of Sardinia (Italy). Particle size analysis of sediments revealed medium or medium-fine intertidal sands and coarse subtidal sands, the latter mainly formed by coralligenous debris. The systematic study was particularly relevant, leading to the identification of 25 species, of which 9 are new records for Sardinia, and 2 are new to science. With these new findings, the total number of species for Sardinia adds up to 47. The species found belong to the families Halechiniscidae (16 species; abundance 2 to 263 ind. 10 cm-2), Batillipedidae (6 species; abundance 2 to 574 ind. 10 cm-2) and Stygarctidae (3 species; abundance 0 to 13 ind. 10 cm-2). The present data confirm the existence of a remarkable diversity, both of intertidal and subtidal tardigrade fauna. Generally, the prevalently siliceous intertidal sands host a few number of species (sometimes with many individuals), while the subtidal sediments, which were mainly calcareous, show a higher number of species often with low density. In fact, in the intertidal sediments only 11 species were found, 5 belonging to Halechiniscidae and 6 to Batillipedidae. In the subtidal sediments, there was a much wider variety; Halechiniscidae showed the highest number of species (16), compared to the remaining families, while Stygarctidae, which were present only in subtidal sediments, accounted only for 3 species. In the intertidal zone the highest value of the diversity index (H') was 2.1 and in the subtidal zone it was 3.3.
TRICHINELLOSIS EMERGENCY IN SARDINIA
M. Liciardi,R. Piroddi
Italian Journal of Food Safety , 2013, DOI: 10.4081/ijfs.2008.1.11
Abstract: Between April 2005 and March 2006 4 cases of human trichinellosis have been confirmed in the Sardinia region(Italy)as a result of the consumption of the row sausages obtained from free ranging pigs slaughtered illegally. To cope with further new outbreaks, the Sardinia region has undertaken series of actions, such as informative campaigns addressed to the consumers, trichinoscopic examination of the susceptible wildlife object of hunting as well as free ranging pigs illegally reared in the areas where human trichinellosis occurred. The investigations conducted so far indicate the absence of responsible parasite in the wild boar, while demonstrating its presence in the pigs reared in free ranging conditions, confirming the presence of some risk factors for the maintenance and spread of the parasite.
Structural features of the Middle Tirso Valley (Central Sardinia - Italy) from geoelectrical and gravity data
T. Andriani,R. Balia,M. Loddo,G. Pecorini
Annals of Geophysics , 2001, DOI: 10.4401/ag-3564
Abstract: The Middle Tirso Valley is located in Central Sardinia and lies between two structural highs, the Marghine-Goceano chain and the Barbagia Paleozoic horst. The geological structures of the area, potentially interesting for its geothermal resources, are rather complex and dominated by two regional faults the Marghine fault and the Nuoro fault which affect the Palaeozoic basement and the Tertiary volcano-sedimentary deposits. Combined modelling of gravity and geoelectrical data defines the shape and extent of this Tertiary basin. The Bouguer anomaly is mainly characterized by a three-dimensional gravity low which has been named Bolotana-Sedilo gravity low , corresponding to a structure generated by collapses attributable to transcurrent and extensional tectonic events. The down faulted zone is filled with a Tertiary low density volcano-sedimentary sequence extending southwards and overlain by Pliocene-Quaternary basalts. Another regional structure named Tirso Fault is proposed
Un’Afrodite riemersa dal mare. La Sardegna e i suoi rapporti con il Mediterraneo
Angiolillo, Simonetta
ArcheoArte : Rivista Elettronica di Archeologia e Arte , 2010,
Abstract: The subject of this study is a small statue with an ancient restoration, probably from Pula, representing Aphrodite binding her sandal. The iconographic type, the stylistic features and, most of all, the kind of marble, that is Paros 1 and Paros 2, tell us the statue is a Greek original, and this is no peculiar thing in Sardinia, where we know a few other sculptures coming from Greece. M. Agus and S. Cara propose the results of archaeometric research on the marble of the statue.
Health and socio-demographic conditions as determinants of marriage and social mobility: Male partner choice in Sardinia, late 19th-early 20th century

Demographic Research , 2010,
Abstract: This paper makes use of data collected from military registers and marriage certificates for the population of Alghero, in Sardinia, for the period 1866-1925, with the aim of investigating the role played by physical characteristics and health in the possibility of social mobility through marriage. Our findings demonstrate that, whereas physical defects and ill health had little impact on the chances of marrying an illiterate woman, these factors did have a negative effect on the chances of marrying a woman who was literate. In a context in which intergenerational social mobility remained limited and the family had the final say on marriage arrangements, it is likely that only healthy individuals were selected for marriages regarded as strategic for the purposes of forming and strengthening family alliances, and/or improving the social position within the community.

Abstract: Forty four consecutive subjects aged 29-58 years (21 males and 23 females) with a clinical diagnosis of heterozygous familial hypercholesterolemia periodically treated every 30 days with LDL-apheresis for statin resistance, were enrolled in this study. A lipid profile was obtained immediately before starting LDL-apheresis, a second profile was obtained within four hours after LDL-apheresis. Chit activity and anti-oxLDL levels were determined with appropriate methods in all patients before and after LDL- apheresis. Total cholesterol, LDL-cholesterol, HDL- cholesterol and triglycerides decreased significantly after LDL-apheresis, while the variations of Chit activity and anti-oxLDL were not significant after LDL-apheresis. The correlation between Chit and total cholesterol was negative (r= –0.44 and –0.50 res- pectively) before and after LDL-apheresis as between Chit and LDL-cholesterol (r= –0.45 and –0.55 respectively). Anti-oxLDL concentration before and after LDL-apheresis positively correlated with Chit activity (r= 0.52 and r = 0.63 respectively), negatively with total cholesterol (r= –0.33 and r = –0.35 res- pectively) and with LDL (r = –0.32 and r = –0.21 respectively). We think that removing LDL with LDL-apheresis the anti-oxLDL/oxLDL ratio could increase and the excess of anti-oxLDL could induce macrophage activation through the surface Fc receptors. Alternatively with high levels of LDL- cholesterol, the deposition of foam cells represent the characteristic evolution of atherosclerosis process. Macrophage activation in the heterozygous familial hypercholesterolemia could represent an attempt for re-modeling the vessel wall, reducing the growth of lipid plaques.
