Research ArticleOpen accessIn the author namesSolving the Robust Design Problem for a Two-Commodity Flow Network with Node FailureNoha Hamdy Radwan, Moatamad Refaat Hassan, Mohamed Eid HusseinThe robust design in a flow network is one of the most important problems. It is defined as searching the optimal capacity that can be assigned to the nodes such that the network still survived even under the node’s failure. This problem is considered NP-hard. So, this study presents a genetic-based algorithm to determine the maximum node capacity for a … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 28 Dec 2020 · 6,593 accessesView PDFCite
Research ArticleOpen accessIn the author namesTHE IMPACT OF ANTIOXIDANTS ON INFLAMMATION AND OXIDATIVE STRESS MARKERS IN OSTEOARTHRITIS RAT MODEL: SCANNING ELECTRON MICROSCOPE INSIGHTSEl Hassan Heidar, FareedF Al Faya, Waleed N. Hassan et al.Osteoarthritis (OA) is characterized by degradation of matrix and destruction of articular cartilage. Articular chondrocytes are solely responsible for the production and maintenance of the extracellular matrix. Therefore, chondrocyte disruption is implicated in cartilage degeneration. Numerous studies have shown that antioxidant treatments are promising therapeutics in cases of OA. This study was designedto examine whether vitamin E protects rat articular … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 19 May 2014 · 7,616 accessesView PDFCite
Research ArticleOpen accessIn the author namesEFFECT OF PIOGLITAZONE ON HEPATIC ULTRA-STRUCTURE AND METABOLIC CHANGES INDUCED BY A HIGH SUCROSE DIET IN RATSMohamed D. Morsy, Ahmed S. Khashaba, Ahmed I. Agamy, Refaat A. EidPioglitazone (Pio) is a PPAR-γ agonist insulin sensitizer has anti-inflammatory activity. Our novel aspect was to investigate its hepatic anti-inflammatory activity at the level of ultra-structure and enzymatic changes in a high sucrose diet animal model. Forty male Sprague Dawley rats were divided into four equal groups: Control; control Pio; high sucrose diet; high sucrose diet Pio treated groups. Fourteen … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 23 Apr 2014 · 6,732 accessesView PDFCite
Research ArticleOpen accessIn the author namesQUERCETIN AMELIORATES DIABETIC NEPHROPATHY IN RATS VIA MODULATION OF RENAL NA+, K+-ATPASE EXPRESSION AND OXIDATIVE STRESSSalah O. Bashir, Mohamed Darwesh Morsy, Hussein F. Sakr et al.Diabetic Nephropathy (DN) is one of most prevalent complications of Diabetes Mellitus (DM), therefore prevention of its development is a important field for researches. Quercetin is a plant flavenoid with hypoglycemic and antioxidant properties that is claimed to have a reno-protective effect in diabetes. This study was designed to investigate the reno-preventive role of Quercetin treatment in terms of biochemical … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 14 Feb 2014 · 8,047 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Effect of Citrullus colocynthis Pulp Extract on the Liver of Diabetic Rats a Light and Scanning Electron Microscopic StudyMohammad Khalil, Gamal Mohamed, Mohammad Dallak et al.Problem statement: The goal of the current investigation was to clarify the effects of Citrullus colocynthis pulp extract on the structure of the liver of diabetic rats at both light and scanning electron microscopic levels. Approach: Forty-eight adult male albino rats were equally allocated into four groups: Group1: control, Group 2: Citrullus colocynthis-treated, Group 3: diabetic rats and Group4: diabetic … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 9,478 accessesView PDFCite
