The effects of Niguldipine pretreatment on cerebral vasospasm after subarachnoid haemorrhage in rabbits
(JOHN WILEY & SONS LTD, 2004)Several different mechanisms contribute to the pathogenesis of cerebral vasospasm after subarachnoid haemorrhage. Whatever these mechanisms are, the vessel contraction is ultimately induced by an increase of free intracellular ... -
Effects of Rhus coriaria L. (Anacardiaceae) on lipid peroxidation and free radical scavenging activity
(JOHN WILEY & SONS LTD, 2004)In order to evaluate the antioxidant potential of Rhus coriaria L. (Anacardiaceae), a well-known spice, the methanolic extract (water-soluble part) was prepared and investigated using free radical-generating systems in ... -
GEOLOGICAL SETTING, PETROGRAPHIC AND GEOCHEMICAL CHARACTERISTICS OF THE CRETACEOUS AND TERTIARY IGNEOUS ROCKS IN THE HEKIMHAN HASANCELEBI AREA, NORTH-WEST MALATYA, TURKEY
(JOHN WILEY & SONS LTD, 1993)Upper Cretaceous to Tertiary igneous rocks outcrop in the Hekimhan-Hasancelebi area, about 80 km to the north-west of Malatya, Central-Eastern Anatolia. These igneous rocks consist of Maastrichtian Bahcedam volcanics, the ... -
Grain size and clay mineralogy of Late Quaternary sediments on a tectonically active shelf, the southern Sea of Marmara: clues to hydrographic, tectonic and climatic evolution
(JOHN WILEY & SONS LTD, 1999)The clay mineral content and grain size composition of sediments obtained from 29 cores (up to 350 cm in length) on the southern Marmara shelves have been analysed in order to determine the effects of climatic, neotectonic ... -
The in vitro antioxidant and antimicrobial activities of the essential oil and methanol extracts of Achillea biebersteini Afan. (Asteraceae)
(JOHN WILEY & SONS LTD, 2004)The essential oil and methanol extracts from A. biebersteinii Afan. (Asteraceae) were evaluated for their antimicrobial and antioxidant activities in vitro. The oil showed stronger antimicrobial activity than the extracts. ... -
