Research ArticleOpen accessIn the abstractPyritization of the Coastal Sediments in the Kelantan Plains in the Malay Peninsula during the HoloceneM.S.K. Enio, J. Shamshuddin, C.I. Fauziah, M.H.A. HusniProblem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of L-Carnitine and Cinnamon Extract Treatment on Lens Crystallins of Rats Fed High Fructose DietMohamed H. Mahfouz, Amany Abd El-Ghaffar, Mona A. Mohamed, Hala M. GhanemProblem statement: Rats fed high dietary fructose are documented to form an acquired model of insulin resistance; the present study aims to investigate possible changes in lens crystallins of rats fed high fructose diet and the effects of administration of each exogenous L-Carnitine (CA) and Cinnamon Extract (CE) on protein glycation, oxidative stress and redox homeostasis in this rat model. … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 3 Aug 2011 · 8,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Soil Biological Properties of Natural and Planted Forests in the Malaysian Tropical Lowland Dipterocarp ForestDaljit Singh Karam, Arifin Abdu, O. Radziah et al.Problem statement: A study was conducted to evaluate and compare the soil biological properties of a natural forest and an 18-year-old stand of Shorea leprosula in Chikus Forest Reserve, Perak, Malaysia. Approach: Soils were sampled at depths of 0-15 cm (topsoil) and 15-30 cm (subsoil) in six subplots (20×20 m) of natural forest (C1) and of a planted S. leprosula … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 29 Jul 2011 · 7,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Evaporation in Degrading the "Oil Lakes"Al Rashed Ahamad, Colin BarkerProblem statement: Oil Spills are degraded by aerobic bacteria, water washing, evaporation and oxidation. In the absence of water the first two of these processes cannot operate. This is the situation in the low rainfall environment of the Kuwaiti desert where oil lakes still persist 20 years after the initial spills. The oils contain longer chain n-alkanes but have lost … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Prevention of Browning in Plantain CultureInnocent Chimereze Onuoha, Chinonye Jemimah Eze, Chibuikem I.N. UnambaProblem statement: The in vitro propagation of plantain (Musa paradisiaca) is still faced with lots of challenges such as blackening or browning of tissues prior to culture due to the oxidation of phenolic compound by polyphenolic oxidase enzyme present in the tissue when excised. Approach: Understanding browning processes in plantain and possible ways of minimizing it during excision of explants … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 15,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccurate Determination of Nonlinear Refractive Index for Some Binary Glass SystemsElSayed MoustafaProblem statement: This study investigates the relation between the nonlinear optical susceptibility (χ(3)) and the ratio (α1/αo-2), then the nonlinear index determination for some binary glass systems. Recently suitable relationship between the oxidation polarizability and the nonlinear optical properties was established for simple oxides glasses. So in this study more attention and investigation is paid to the trend of that … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractCardioprotective Effect of Lagenaria siceraria (Molina) Standley (Cucurbitaceae) Fruit Juice on Doxorubicin Induced Cardiotoxicity in RatsM. Hassanpour Fard, G. Naseh, S. L. Bodhankar, M. DikshitProblem statement: The cardio toxicity of Doxorubicin (Dox) has limited its use as an anticancer drug. The aim of present study was to investigate the cardio protective effect of Lagenaria Siceraria (Cucurbitaceous) Fruit Juice (LSFJ) against the cardio toxicity of Dox in rats. Approach: Male wistar rats (250-300 g) were randomly divided into four groups. Group I- was control, Group … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 8,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoltammetric Detection of Mn(II) in Blood Sample at C60 and MWCNT Modified Glassy Carbon ElectrodesMuhammed Mizher Radhi, Wee Tee Tan, Mohamad Zaki B. Ab Rahman, Anuar Bin KassimProblem statement: Glassy carbon electrode GCE was modified with different microparticles to increase the efficiency of analysis Mn2+ in blood samples by cyclic voltammetry and applied for the detection of trace Mn(II) by oxidation process. Approach: The structure and composition of the modified GCE processed by using Carbon Nanotubes CNT and C60 to produce two modified electrodes CNT/GCE and C60/GCE, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,489 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDFCite
