The Middle Euphrates region extends between the regions Jazirah and Northern Levant; it follows the course of the Euphrates from the south flanks of the Taurus mountains in Turkey almost to the modern borderline to Iraq. The settlement area drawn out between steppes in the east and in the west owes its particular character to just that life line with its fat soils but also to the trade routes meeting at the Euphrates Bend and connecting Anatolia to Mesopotamia and the Syrian east to the Levant. Especially for the 3rd millennium, finds and findings from the area under consideration show great cultural variety and demonstrate the different influences by the neighbouring regions that meet here…
The oxidizing agent tertiary butyl hydroperoxide induces disturbances in spindle organization, c-meiosis, and aneuploidy in mouse oocytes
1996
It has been recently proposed that a concomitant generation of oxidative stress of oocytes with increasing maternal age may be a major factor responsible for the age-related increase in aneuploid conceptions. As a preliminary step in the testing of this hypothesis, we need to confirm that oxidative stress in itself can induce errors in chromosome segregation. In order to achieve this goal, germinal vesicle (GV)-stage mouse oocytes from unstimulated ICR and (C57BL x CBA) F1 hybrid female mice were matured in vitro for 9 h for metaphase I (MI) oocytes or 16 h for metaphase II (MII) oocytes in the presence of varying concentrations of the oxidizing agent tertiary-butyl hydroperoxide (tBH). MII…
Assaying waterborne psychoactive drugs by the response to naturalistic predator cues in the stickleback (Gasterosteus aculeatus)
2020
Abstract Ecotoxicological effects of psychiatric drugs and drug metabolites released by the human population are of increasing environmental concern. In this study we evaluate behavioral responses to visual predator cues in wild caught three-spined stickleback (Gasterosteus aculeatus) after exposure to water-born citalopram, a widely prescribed selective serotonin reuptake inhibitor with antidepressant and anxiolytic effects. Fish were exposed to ecological relevant concentrations of citalopram (0.15 or 1.5 μg L−1) for 10 or 20 days. After drug exposure, individual fish were moved to a test arena where they were exposed to two naturalistic visual predator cues; a shadow from beneath, which …
THE ROLE OF CYTOKININS AND ETHYLENE INHIBITORS ON LENTICEL HYPERTROPHY GENERATION AND ETHYLENE PRODUCTION IN IN VITRO CULTURES OF POPULUS EUPHRATICA …
1995
Populus euphratica Olivier is native to the Irano—Turanian areas (Middle East). Elche (Alicante province, SE Spain) is known to be its only European location. Nodal segments from root shoots were established in vitro in a Murashige and Skoog medium supplemented with several cytokinins. Ethylene inhibitors AgNO3 and CoCl2 were used in combination with kinetin. Hormone-free media supplemented with sucrose (20–60 mg 1−1) was also tested. Ethylene was measured by gas chromatography, and both the percentage of sprouting shoots and lenticel hypertrophy in cultures were recorded. Ethylene production was higher in cultures supplemented with cytokinins (especially with meta-topolin), with high sprou…

Parasitoids of Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) recovered in western North America and first record of its egg parasitoid …
2012
The parasitoid complex of the western conifer seed bug, Leptoglossus occidentalis, was studied in British Columbia and California on Pinus monticola and P. contorta var. latifolia. Three egg-parasitoid species were identified: Gryon pennsylvanicum (Hymenoptera: Platygastridae), Ooencyrtus johnsoni (Hymenoptera: Encyrtidae) and Anastatus pearsalli (Hymenoptera: Eupelmidae). Leptoglossus occidentalis represents a new host record for O. johnsoni, and California is a new distribution record for G. pennsylvanicum. Gryon pennsylvanicum was the dominant species during the entire oviposition period of the bug, reaching peak parasitization levels in July (25%). Ooencyrtus johnsoni and A. pearsalli e…
Eupelmus spermophilus Silvestri (Hymenoptera: Chalcidoidea), an Indigenous Olive Seed Wasp Potentially Harmful to Olive Growing in the Western Cape, …
2021
The objectives of this study were the specific taxonomic confirmation of the main olive seed wasp (OSW) attacking commercial olives in the Western Cape, to investigate monitoring methods and seasonal occurrence of OSW, to determine the potential economic damage of infestations, and to ascertain the geographic distribution of OSW in the regions where olives are cultivated in the Western Cape. Morphological and molecular methods were used to identify all the species obtained from cultivated olives at two trial sites near Stellenbosch and Agter-Paarl. Eupelmus spermophilus Silvestri (Hymenoptera: Chalcidoidea) was by far the most frequent and widespread olive seed wasp. Monitoring with yellow …
Chemical constituents and antiproliferative activity of Euphorbia bivonae
2011
Euphorbia is a genus of plants belonging to the family Euphorbiaceae, consisting of about 2160 species. This family occurs mainly in the Indo-Malayan region and tropical America. Euphorbia also has many species in non-tropical areas such as the Mediterranean area, the Middle East, South Africa, and southern USA. Phytochemical studies of species from the genus Euphorbia report the presence of skin-irritating and tumor-promoting diterpenoids, several macrocyclic diterpenoids with antibacterial, anticancer, PGE2-inhibitory, antifeedant, anti-HIV, and analgesic activities. Some of the Euphorbiaceae species are used in folk medicine for the treatment of skin diseases, gonorrhea, migraines, intes…

Nuova stazione di Euphorbia serrata in Sicilia
2007
A new record of Euphorbia serrata (Euphorbiaceae) from Sicily. - Euphorbia serrata L. is reported from a new locality in Sicily near Mazara del Vallo (Trapani). Data on the biological cycle and the phytocoenosis in the new Sicilian locality are also reported.
