T1  - Nomes of Lower Egypt in the early Fifth Dynasty
JF  - E&G Quaternary Science Journal
N2  - Having control over the landscape played an important role in the geography and economy of Egypt from the predynastic period onwards. Especially from the beginning of the Old Kingdom, we have evidence that kings created new places (funerary domains) called (centers) and (Ezbah) for the equipment of the building projects of the royal tomb and the funerary cult of the king, as well as to ensure the eternal life of both kings and individuals. Kings used these localities in order to do so, and they oftentimes expanded the border of an existing nome and created new establishments. Consequently, these establishments were united or divided into new nomes. The paper discusses the geography of Lower Egypt and the associated royal domains in the early Fifth Dynasty based on the new discoveries from the causeway of Sahura at Abusir.
N2  - Die geographische Unterteilung des Landes als Voraussetzung des Zugriff auf die Ressourcen des Landes spielte für die Wirtschaft Ägyptens und königliche Bauprojekte seit der prädynastischen Zeit eine wichtige Rolle. Um die landwirtschaftliche Nutzung des Landes auszuweiten und diesen Zugriff gleichzeitig zu sichern, begründeten die ägyptischen Könige Wirtschaftsanlagen (Grabdomänen) an schon bestehenden oder neu geschaffenen Siedlungen. Da sich der größte Teil der agrarisch nutzbaren Fläche im Delta befand, wurde im Laufe der Zeit auch das bestehende Gausystem dieses Gebietes mehrfach verändert. Das Papier erörtert die Geographie des Deltas in der frühen fünften Dynastie auf der Grundlage neuer Entdeckungen vom Aufweg des Pyramidenbezirkes des Sahure in Abusir (Abstract was translated by Eva Lange-Athinodorou.).

T1  - Hepatoprotective potential of Malvaviscus arboreus against carbon tetrachloride-induced liver injury in rats
JF  - PLoS ONE
N2  - Malvaviscus arboreus Cav. is a medicinal plant belonging to family Malvaceae with both ethnomedical and culinary value; however, its phytochemical and biological profiles have been scarcely studied. Accordingly, this work was designed to explore the chemical composition and the hepatoprotective potential of M. arboreus against carbon tetrachloride (CCl\(_4\))-induced hepatotoxicity. The total extract of the aerial parts and its derived fractions (petroleum ether, dichloromethane, ethyl acetate, and aqueous) were orally administered to rats for six consecutive days, followed by injection of CCl\(_4\) (1:1 v/v, in olive oil, 1.5 ml/kg, i.p.) on the next day. Results showed that the ethyl acetate and dichloromethane fractions significantly alleviated liver injury in rats as indicated by the reduced levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TB), and malondialdehyde (MDA), along with enhancement of the total antioxidant capacities of their livers, with the maximum effects were recorded by the ethyl acetate fraction. Moreover, the protective actions of both fractions were comparable to those of silymarin (100 mg/kg), and have been also substantiated by histopathological evaluations. On the other hand, liquid chromatography-high resolution electrospray ionization mass spectrometry (LC‒HR‒ESI‒MS) metabolomic profiling of the crude extract of M. arboreus aerial parts showed the presence of a variety of phytochemicals, mostly phenolics, whereas the detailed chemical analysis of the most active fraction (i.e. ethyl acetate) resulted in the isolation and identification of six compounds for the first time in the genus, comprising four phenolic acids; β-resorcylic, caffeic, protocatechuic, and 4-hydroxyphenylacetic acids, in addition to two flavonoids; trifolin and astragalin. Such phenolic principles, together with their probable synergistic antioxidant and liver-protecting properties, seem to contribute to the observed hepatoprotective potential of M. arboreus.
