Khalil, W. K. B., W. S. Hasheesh, M. - A. S. Marie, H. H. Abbas, and E. A. Zahran, "Assessment the Impact of 17α-Methyltestosterone Hormone on Growth, Hormoneconcentration, Molecular and Histopathological Changes in Muscles and Testis of Nile Tilapia, Oreochromis Niloticus", Life Science Journal, vol. 8, issue 3, 2011. AbstractCU-PDF.pdf

The present study was designed to explain clearly why methyltestosterone is widely used by the Egyptian producers of farmed tilapia and also to investigate its fate in treated fish to guarantee that no hazards on consumers, producers and on the environment. In this study, samples of untreated and treated Nile tilapia were collected at several time intervals. Water quality parameters were within the acceptable range for fish growth. The present analyses showed highly significant increase in body weight, body length, condition factor (K), HSI and GSI, between different time intervals (April - November, 2009) in the untreated control and treated groups. On the other hand, plasma testosterone and residual concentration of testosterone hormone in muscle showed highly significant differences between the studied months in untreated control and treated groups. Molecular biological analyses revealed that methyltestosterone was able to induce DNA fragmentation and molecular genetic variability (using RAPD- PCR fingerprinting pattern) in the testis tissues of the treated Nile tilapia; Oreochromis niloticus, which was higher in the first four studied months than the untreated control tilapia. Additionally, histopathological examination showed no changes and no traces of hormone accumulation in the muscle structure. Testis showed moderate number of spermatozoa followed by increasing in number of spermatozoa at the end of the study.

Ibrahem, M. D., Iman, B. Shaheed, A. H. El-Yazeed, and H. Korani, "Assessment of the Susceptibility of Polyculture Reared African Catfish and Nile Tilapia to Edwardsiella Tarda", Journal of American Science, 2011. Abstract

The study aimed to clarify the relative susceptibility of polyculture rearing African sharptooth catfish (Clarias gariepnus) and Nile tilapia (Oreochromis niloticus) , the two main reared species in Egypt to Edwardsiella tarda. Experimental infection of catfish and Nile tilapia with E. tarda was carried out after determination of the Mean lethal dose in African catfish (LC50). Infectivity pattern and pathology of E. tarda in catfish and Nile tilapia were tested via intra-peritoneal inoculation of 0.2ml of 104 CFU/ml of the bacteria at 25 oC. The mortality rates were 70% and 60% in catfish and Nile tilapia respectively.

Attallah, A. A., S. O. Abdallah, M. M. Omran, K. Farid, and Y. M. Shaker, "Assessment of Hepatic Fibrosis Stages in Hepatitis C Virus Infected Patients Using Biomarkers in the Blood", Journal of American Science, vol. 7, issue 12, pp. 799-805, 2011. AbstractCU-PDF

Background: An intensive research effort in the field of non-invasive evaluation of liver fibrosis has recently permitted the description of several blood markers of fibrosis, mainly in chronic hepatitis C (CHC) patients. Our aim was to evaluate the diagnostic performance of a panel of simple blood markers of liver fibrosis in CHC patients. Materials and Methods: One hundred and thirty two patients with CHC evaluated for deciding on antiviral therapy were included. We used receiver operating characteristic (ROC) curves and a stepwise combination algorithm was developed to assess and compare the diagnostic accuracy of blood markers. Results: The areas under the ROC curves of AST/ALT ratio, albumin, platelet count, APRI and fibronectin for discriminating advanced liver fibrosis (F3-F4) were 0.58, 0.73, 0.76 , 0.73 and 0.74; respectively. The AUC of combined markers score based on AST-ALT ratio, albumin, fibronectin and platelets count was 0.86 for advanced liver fibrosis patients. The combined markers correctly classified 35 positive patients from 43 patients with 81% sensitivity and classified 64 patients as negative from a total of 89 patients with 72% specificity. Discussions.we have developed multivariate discriminate analysis (MDA), a function may contribute to differentiating advanced fibrosis in patients with CHC. The MDA function is based on easily and routinely analyzed four blood markers as noninvasive, reproducible, quantitative, precise, accurate and low cost method that can be applied to patients who either have contraindications or refuse liver biopsy for the management of their HCV infection.

Abu-Taleb, A. M., K. E. - Deeb, and F. O. Al-Otibi, "Assessment of Antifungal Activity of Rumex Vesicarius L. and Ziziphus Spina-christi (L.) Willd.extracts Against Two Phytopathogenic Fungi", African Journal of Microbiology Research, 2011. Abstract

The preliminary phytochemical screening of extracts of Rumex vesicarius L. and Ziziphus spina-christi (L.) Willd. showed the presence of compounds that are biologically active against the two root rot pathogens Drechslera biseptata and Fusarium solani in vitro. The relative efficacy of this action, however, differed according to the extracted plant, solvent used, extract concentration, the target fungus and phase of growth. Ethanolic extract ranked first, followed by the remaining aqueous layer fraction. Eight flavonoid subfractions (rutin, quercetin, myricetin, apigenin, quercetin-3-O-galactoside, luteolin, kaempherol and kaempherol-3-O-robinoside) and six flavonoid subfractions (apigenin-7-O-glucoide, quercitrin, quercetin, isovitexin, rutin and quercetin-3-O lucoside-7-O-rhamnoside) were isolated from the remaining aqueous layer fraction of R. vesicarius and Z. spina-christi, respectively. Generally, spore production and germination as well as cellulolytic and pectolytic activity of F. solani were affected by plant extracts more than that of D. biseptata. F. solani failed completely to produce spores when treated

Afify, A. E. - M. M. R., E. A. Shalaby, and H. S. El-Beltagi, "Antioxidant Activity of Aqueous Extracts of Different caffeine Products", Journal of Medicinal Plants Research, vol. 5, issue 20, pp. 5071-5078, 2011. AbstractCU-PDF.pdf

The antioxidant activity of water extracts (cold and hot) of six caffeine products were carried out. The extracts were screened for total polyphenol contents and antioxidant activity using DPPH, ABTS methods and reducing power method at 50 and 100 ?g/ml after 15 and 30 min using BHA and Caffeine as standard compounds. The results indicated that, the hot water extracts for different caffeine products showed high antioxidant activity more than cold extracts and this activity was time and concentration dependent. In addition, the activity was higher against ABTS radical more than DPPH and reducing power methods. Also, there is positive correlation between the antioxidant and reducing compounds presented in water extracts of different caffeine products. The results of HPLC showed that fresh tea leaves are rich in flavanol monomers known as catechins. The most abundant catechin derivatives in green tea are EGC, EGCG and GC. On the other hand, EGCG and GC are major catechin derivative in different caffeine product except El-Fakher tea and Cacao. Generally, these beverages had high antioxidant capacities and total phenolic contents and could be important dietary sources of antioxidant phenolic for prevention of diseases caused by oxidative stress.
