Research ArticleOpen accessIn the abstractInternalizing Versus Non-internalizing Receptors for Targeting L-Methioninase to Cancer CellsXiao-Ping Zang, Naveen R. Palwai, J. T. Pento, Roger G. HarrisonWe reported previously that L-methioninase targeted to the urokinase receptor of MCF-7 breast cancer cells is significantly more effective in inhibiting cell proliferation and migration than free L-methioninase both in vitro and in vivo. L-methioninase was targeted by linking at its amino terminus to an amino-terminal fragment (ATF) of urokinase. The ATF was selected for targeting because is has previously … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 3 · 30 Sep 2006 · 7,817 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEFFECT OF POLYETHYLENE BLACK PLASTIC MULCH ON GROWTH AND YIELD OF TWO SUMMER VEGETABLE CROPS UNDER RAIN-FED CONDITIONS UNDER SEMI-ARID REGION CONDITIONSAtif Y. MahadeenWater use efficiency in agriculture can be enhanced by several strategies mainly by reducing evaporation from the soil surface. The mulching techniques were being used widely in irrigated crop production worldwide. The mulching techniques can be also implemented in summer vegetables production under rain-fed conditions. The current study aimed at evaluating the effect of polyethylene black plastic mulch on growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 29 Jan 2014 · 9,007 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,983 accessesView PDF Cite

Research ArticleOpen accessIn the abstractControlling Ammonia Volatilization by Mixing Urea with Humic Acid, Fulvic Acid, Triple Superphosphate and Muriate of PotashShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Inefficient use of inorganic fertilizer such as urea is caused by substantial losses of ammonia when urea is surface-applied. Ammonia losses can be controlled by adding acidic material such as TSP, HA or FA. In order to reduce ammonia loss and retain soil exchangeable ammonium and available nitrate as well as producing complete organic based fertilizer, this study … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 9,540 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReduction of Ammonia Loss from Urea through Mixing with Humic Acids Isolated from Peat Soil (Saprists)Regis Bernard, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Application of urea as a source of nitrogen fertilizer has an adverse effect on ammoniacal loss to the environment. This study was conducted to reduce ammonia loss from urea by mixing with Humic Acids (HA) isolated from Saprists peat. Approach: The effects of urea amended with four different amounts of humic acids, 0.25, 0.50, 0.75 and 1.00 g … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,846 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSPECTRAL DOMAIN FEATURES FOR OVARIAN CANCER DATA ANALYSISAhmed Farag Seddik, Riham Amin Hassan, Mahmoud A. FakhreldeinThe early detection of cancer is crucial for successful treatment. Medical researchers have investigated a number of early-diagnosis techniques. Recently, they have discovered that some cancers affect the concentration of certain molecules in the blood, which allows early diagnosis by analyzing the blood mass spectrum. Researchers have developed several techniques for the analysis of the mass-spectrum curve analysis and used … …Journal of Computer Science, Vol. 9, Issue 8 · 9 Jul 2013 · 6,915 accessesView PDF Cite
