Acta Palaeomedica. International Journal of Palaeomedicine
No full textThe first issue of this journal aims to offer its new readership with a very interesting set of topics, ranging from the Black Death to family interrelations of Egyptian pharaohs, from the discovery of skeletons dated to the 4th century BC in Syracuse to the study of cranial trepanation in mummies in Cuba, and much more, including some book reviews.

Introduction
No full textThis volume collects the best scientific contribution presented in the 3rd World Conference on Terraced Landscapes held in Italy from October 6–15, 2016, offering a deep and multifaceted insight into the remarkable heritage of terraced landscapes in Italy, in Europe, and in the world (America, Asia, Australia). It consists of two parts: a geographical overview on some of the most important terraced systems in the world (first part) and a multidisciplinary approach that aims to promote a multifunctional vision of terraces, underlining how these landscapes meet different needs: cultural and historical values, environmental and hydrogeological functions, quality and variety of food, community empowerment, and sustainable development (second part). The volume offers a great overview on strengths, weaknesses, functions, and strategies for terraced landscapes all over the world, summarizing in a final manifest the guidelines to provide a future for these landscapes as natural and cultural heritage
Acta Palaeomedica - International Journal of Palaeomedicine
No full textIn this issue we celebrate traditional osteological methods in papers addressing deviant burials and post-mortem mutilation as well as evidence of autoptic practices, respectively from Tuscany and Spain, a comprehensive analysis of malaria in Ancient Egypt, and congenital spine anomalies in prehistoric Sicily. This set of papers is corroborated by additional contributions from Australia and Germany presenting bioarchaeological findings in South Australia and the importance of plaster casts in German collections.

Alpha-1-adrenoceptor mediated formation of glycerophosphoinositol 4-phosphate in rat heart: possible role in the positive inotropic response
No full textIn the present study, we investigated whether phospholipase A2 (PLA2)/lysophospholipase activity producing glycerophosphoinositols from phosphoinositides was operating in rat heart and could be stimulated by alpha1-adrenergic agonists. PLA2/lysophospholipase activity was found in homogenates from rat right ventricles. The stimulation of PLA2/lysophospholipase activity by noradrenaline (NA) was prevented either by the alpha1-adrenergic antagonist prazosin or arachidonyl trifluoromethyl ketone, a selective inhibitor of the 85-110 kDa, sn-2-arachidonyl-specific cytosolic PLA2. The selective alpha1-adrenergic agonist phenylephrine induced a concentration- and time-dependent increase in glycerophosphoinositol (GroPIns) and glycerophosphoinositol 4-phosphate (GroPIns4P) in rat right ventricle slices prelabelled with D-myo-[3H]inositol. In electrically driven strips of rat right ventricles, prelabelled with D-myo-[3H]inositol, the positive inotropic effect induced by 20 microM NA in the presence of propranolol was accompanied by the formation of GroPIns and GroPIns4P. The concentration of the formed GroPIns4P (1.33+/-0.12 microM, N = 6) was similar to that previously reported to inhibit the Na+/Ca2+ exchanger in cardiac sarcolemmal vesicles (Luciani S, Antolini M, Bova S, Cargnelli G, Cusinato F, Debetto P, Trevisi L and Varotto R, Biochem Biophys Res Commun 206: 674-680, 1995). These findings show that the stimulation of alpha1-adrenoceptors in rat heart is followed by an increase in the formation of GroPIns4P, which may contribute to the positive inotropic effect of alpha1-adrenergic agonists by inhibition of the Na+/Ca2+ exchanger
The Covid-19 pandemic as a communication responsibility and opportunity for paleopathology
No full textNarrating the famous Plague of Athens (430-426 BC) in its destructive manifestation, Thucydides was the first Western author to offer in his History of the Peloponnesian War (2.51) a compelling description of immunity acquired against a highly lethal infectious agent:[...] more often the sick and the dying were tended by the pitying care of those who had recovered, because they knew the course of the disease and were themselves free from apprehension. For no one was ever attacked a second time, or not with a fatal result [δὶς γὰρ τὸν αὐτόν, ὥστε καὶ κτείνειν, οὐκ ἐπελάμβανεν.] » (1
Paesaggi terrazzati d'Italia : eredità storiche e nuove prospettive
No full textLa presenza di versanti terrazzati a fini agricoli mostra in Italia aspetti di indubbia straordinarietà, in termini di superfici occupate e di varietà tipologiche. Il libro rende ragione di un'articolata distribuzione in rapporto ai fattori geologici, morfologici e climatico-ambientali, nonché alla luce delle specificità regionali dei processi insediativi, demografici e socio-economici.
Le profonde trasformazioni che hanno investito i rilievi alpini, appenninici e insulari soprattutto a partire dal secolo scorso, hanno comportato un destino di prevalente abbandono dei terrazzamenti, anche se con modalità di risposta diverse a seconda dei casi, e con non pochi esempi di resistenza, cui si sono affiancate negli ultimi anni esperienze di recupero e valorizzazione.
Le analisi dei processi di genesi storica e adattamento ambientale, delle forze sociali ed economiche che ne regolano l'evoluzione, restituiscono in questo volume le grandi questioni conoscitive che i paesaggi terrazzati pongono con la loro diffusa presenza in Italia, offrendo uno strumento utile per le politiche territoriali ad essi indirizzate
Paesaggi terrazzati dell’arco alpino : atlante
No full textI versanti terrazzati si trovano oggi di fronte a un bivio: abbandono per "insostenibilità" economica o riscoperta come modello di territorialità sostenibile. Il volume presenta i risultati ottenuti all'interno di un progetto europeo transnazionale, condotto in cinque Paesi e in otto aree-pilota, i quali documentano le tipologie formali e costruttive dei manufatti territoriali terrazzati in essi presenti, il loro stato di uso e conservazione, le prospettive di recupero attuale e possibile, la copertura vegetale, coltivata e spontanea, i problemi idro-geologici che li interessano, e dunque i rischi di degrado o sparizione, ma anche le opportunità di salvaguardia e valorizzazione di un paesaggio culturale di straordinario valore
