Cytotoxic neo-clerodane diterpenes from Stachys aegyptiaca
2018
Abstract Two new E/Z neo-clerodane diterpene isomers, trivially named stachaegyptin D (1) and E (2), together with known compounds, stachysolon monoacetate (3) and stachysolon diacetate (4), were isolated from an organic-solvent extract of the medicinal herb Stachys aegyptiaca. Structures were elucidated by a combination of spectroscopic methods, including HREIMS, 1H, 13C, DEPT, and 2D NMR analysis, as well as, first time X-ray analysis for stachysolone (3). All isolated metabolites showed some activity against the human hepatocellular cell line, HepG2. Compound 4 was the most active with an IC50 of 59.5 μM.
In Vitro and In Vivo Antimalarial Activity Assays of Seeds from Balanites aegyptiaca: Compounds of the Extract Show Growth Inhibition and Activity ag…
2011
Balanites aegyptiaca(Balanitaceae) is a widely grown desert plant with multiuse potential. In the present paper, a crude extract fromB. aegyptiacaseeds equivalent to a ratio of 1 : 2000 seeds to the extract was screened for antiplasmodial activity. The determined IC50value for the chloroquine-susceptiblePlasmodium falciparumNF54 strain was 68.26 . Analysis of the extract by gas chromatography-mass spectrometry detected 6-phenyl-2(H)-1,2,4-triazin-5-one oxime, an inhibitor of the parasitic M18 Aspartyl Aminopeptidase as one of the compounds which is responsible for thein vitroantiplasmodial activity. The crude plant extract had a of 2.35 and showed a dose-dependent response. After depletion…
Multiple Linear Regression to predict larvicidal activity against <em>Aedes aegypti </em>mosquito
2017
Vector-borne diseases are one of the important health problems in most tropical countries. Aedes aegypti is an important vector for transmission of dengue, yellow fever, chikungunya, arthritis, and Zika fever. According to the World Health Organization, it is estimated that Ae. aegypti causes 50 million infections and 25,000 deaths per year. The emerging scenario highlights that the eco-friendly and effective control measures for mosquito vectors is of crucial importance. One of the most effective vector control measures has been the use of larvicidal compounds however; this success was short lived due to development of resistance against them in many mosquito strains, ecological imbalance …

Political Action Beyond Resistance: Arendt and "Revolutionary Spirit" in Egypt
2016
The article examines what it calls the "politics-as-resistance" frame in contemporary political theory, originating in the works of Michel Foucault and Judith Butler. This way of organizing political experience is contrasted with Hannah Arendt's political thought, particularly her writings on revolutionary action. Arendt's often overlooked – and partly unpublished – passages on virtù and fortuna are further suggested as important additions to her thinking on action. I argue that Arendt's "world-centric" approach can illuminate certain aspects of political experience that remain dimmed in the more subject-oriented politics-as-resistance frame. Particular focus is paid to the austere notion o…
Astronomia e astrologia nella Tarda Antichità: il caso di Ipazia
2010
In the year dedicated to astronomy, the contribution is a tribute to Hypatia, the first woman scientist and symbol of love for truth, reason and science, who was born and lived in Alexandria in Egypt in the late 4th and early 5th century. The figure and the historical and cultural context in which the first woman scientist lived her life in its practical, scientific and political aspects is reconstructed through the works of Synesius, a student of Hypatia and future bishop of Ptolemais.
Diaspora żydowska w Egipcie w czasach biblijnych
2015
Deportations of Jews into the Babylonian captivity began a period of diaspora, because a part of the inhabitants of Judea took shelter in Egypt. In the fifth century BC, on the island of Elephantine – an island in the Nile, near the First Cataract – a colony of Jewish soldiers, who served in the army of Pharaoh, was created. Moreover, a temple following the templein Jerusalem was built there. After the conquest of Egypt, made by Alexander the Great, the Jewish Diaspora intensively developed. Jews were invited to settle in the newly built port city – Alexandria, which became the capital of the whole Egypt, as well as the scientific and artistic centre.The Judaic literature in Greek language,…

Induction of Hsp70 by the Herbicide Oxyfluorfen (Goal) in the Egyptian Nile Fish, Oreochromis niloticus
1999
This paper deals with the expression of the biomarker hsp70 in the liver and kidney of the freshwater fish Oreochromis niloticus following exposure to the herbicide oxyfluorfen (Goal). Fishes were exposed to three concentrations, the 96-h LC50 (3 mg/L), the 96-h (1/2)LC50 (1.5 mg/L), and the 96-h (1/4)LC50 (0.75 mg/L) of oxyfluorfen for 6, 15, and 24 days, respectively, and samples were taken at three different time periods for each concentration. The livers responded to the herbicide by an induction of the expression of both the constitutive (hsp75; Mr 75 kDa) and the inducible (hsp73; Mr 73 kDa) hsp70 proteins. In kidney, the herbicide induced a time-dependent increase in the expression o…
