Sulla tossicità dei tannini vegetali e sintetici in ratti trattati mediante scarificazione cutanea. Rilievi anatomo-istopatologici sull’apparato tegumentario.

In ratti trattati con tannini vegetali e sintetici per scarificazione cutanea si sono rilevate espressioni reattive escariformi a diverso gradiente di gravità che mentre riparano in breve tempo i soggetti in sperimentazione con tannini vegetali, permangono a lungo con escare focali remittenti in quelli trattati con tannini sintetici

Sulla tossicità dei tannini vegetali e sintetici in ratti trattati per aerosol. Rilievi anatomo-istopatologici sull’apparato respiratorio e cardiaco.

Gli AA. descrivono i reperti anatomo-istopatologici rilevati a carico dell'apparato respiratorio e cardiaco in ratti trattati con tannini vegetali e sintetici per aerosol. Vengono messe in risalto le modificazioni vascolo-distrofiche polmonari più significative nel trattamento con tannini sintetici

The Byzantine Church of the Nutrition in Nazareth rediscovered

Although Nazareth has usually been seen by scholars as a relatively minor Byzantine pilgrimage centre, it contained perhaps the most important ‘lost’ Byzantine church in the Holy Land, the Church of the Nutrition ‐ according to De Locis Sanctis built over the house where it was believed that Jesus Christ had been a child. This article, part of a series of final interim reports of the PEF-funded ‘Nazareth Archaeological Project’, presents evidence that this church has been discovered at the present Sisters of Nazareth convent in central Nazareth. The scale of the church and its surrounding structures suggests that Nazareth was a much larger, and more important, centre for Byzantine-period pilgrimage than previously supposed. The church was used in the Crusader period, after a phase of desertion, prior to destruction by fire, probably in the 13th century

The Ecology of Crusading: Investigating the Environmental Impact of Holy War and Colonisation at the Frontiers of Medieval Europe

The Crusades in the Near East, eastern Baltic and Iberian Peninsula (in the context of the Reconquest/reconquista) were accompanied by processes of colonisation, characterising the expansion of medieval Europe and resulting in the creation of frontier societies at the fringes of Christendom. Colonisation was closely associated with ? indeed, depended on ? the exploitation of local environments, but this dimension is largely missing from studies of the crusading frontiers. This paper, the product of a European Science Foundation Exploratory Workshop on 'The Ecology of Crusading' in 2009, surveys the potential for investigating the environmental impact of the crusading movement in all three frontier regions. It considers a diverse range of archaeological, palaeoenvironmental and written sources, with the aim of situating the societies created by the Crusades within the context of medieval colonisation and human ecological niche construction. It demonstrates that an abundant range of data exists for developing this largely neglected and disparately studied aspect of medieval frontier societies into a significant research programme.
