Research ArticleOpen accessIn the abstractMOLECULAR SWITCH THAT CONTROLS THE FLUX OF LINOLEIC ACID INTO N-6 OR N-3 POLYUNSATURATED FATTY ACIDS IN MICROORGANISMSMingxuan Wang, Jianxin Chen, Huaiyuan Zhang, Yuanda SongPolyunsaturated Fatty Acids (PUFA) of the n-6 and n-3 series play important roles in nutrition. Microorganisms are important sources of n-6 and n-3 fatty acids; however, most produce either n-6 or n-3 fatty acids as the major PUFAs and very few produce both. This differential production suggests that PUFAs metabolic pathway is strictly controlled in microorganisms. The major pathway of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 2 Jul 2014 · 7,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT 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 · 6,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECTS STUDY OF NIGELLA SATIVA, ITS OIL AND THEIR COMBINATION WITH VITAMIN E ON OXIDATIVE STRESS IN RATSAmr A. RezqAntioxidants or free radical scavengers are very important in protecting the living cells against any damage induced by free radicals. The effects of Nigella Sativa Extract (NSE), Nigella Sativa Oil (NSO) and Vitamin E (Vit. E) and the combination of NSE or NSO with Vit. E on potassium bromate (KBrO3)-induced oxidative stress in male rats were investigated. Forty nine Sprague … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 23 Apr 2014 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractISOLATION AND CHARACTERIZATION OF RHIZOBIA AND PLANT GROWTH-PROMOTING RHIZOBACTERIA AND THEIR EFFECTS ON GROWTH OF RICE SEEDLINGSK. Z. Tan, O. Radziah, M. S. Halimi et al.Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were isolated from rice and legume roots, respectively, at four locations … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 15 Apr 2014 · 10,906 accessesView PDFCite

Asiedu-Gyekye Isaac, Awortwe Charles, A. Antwi DanielAllium sativum is cultivated in the northern part of Ghana and has gained widespread use as chemoprotective, in curing hypertension, impotence and erectile dysfunction. The multipurpose use together with its aphrodisiac activity has resulted in the widespread use of this plant medicine both in meals and as herbal medications. Safety assessment of this plant however is rare. The present study … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 30 Jan 2014 · 7,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractHEPATOTOXIC EFFECT OF ITRACONAZOLE IN EXPERIMENTAL RATSMohammed El-Hassan Abdelmaged KemeirItraconazole is a widely used antifungal drug. In situations such as managing patients with gastrointestinal basidiobolomycosis, third of which cases world-wide occur in the southwestern region of Saudi Arabia, prolonged treatment with this drug is required. Thus, this is study was designed to investigate the hepatotoxicity of long term administration of itraconazolein in Wistar rats. Two groups of rats were … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 1 · 30 Jan 2014 · 9,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,139 accessesView PDFCite
