Research ArticleOpen accessIn the abstractImmunomodulatory and In vivo Antiplasmodial Activities of Propolis ExtractsSyamsudin, Rita Marleta Dewi, KusmardiProblem statement: Malaria caused by various species of prozoan parasites, Plasmodium. The exact mechanism of humoral immunity in eliminating Plasmodium is not completely understood. However, an antimalarial antibody is strongly suspected to play important role in immunity. The purpose of this research was to evaluate the immunomodulator and antiplasmodial activities of Indonesian propolis extracts. Approach: Thirty male BALB/c mice weighing … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro and In vivo Anti-Microbial Effects of Nigella sativa Linn. Seed Extracts Against Clinical Isolates from Skin Wound InfectionsMariam A. Abu-Al-BasalcProblem statement: The developing microbial resistance to the existing anti-microbial agents has become a real challenge and a serious problem facing patients suffering from skin infections. Seeds of Nigella sativa have been used for a long time in folk medicine for the treatment of such infections. Production of new potent agents is urgently needed, especially for hospitals and health centers. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing the Urea-N Use Efficiency in Maize (Zea mays) Cultivation on Acid Soils using Urea Amended with Zeolite and TSPOsumanu Haruna Ahmed, Aminuddin Hussin, Husni Mohd Hanif Ahmad et al.Problem Statement: Ammonia loss significantly reduces urea-N use efficiency in crop production. Efforts to reduce ammonia loss are laboratory oriented, as such limited in reflecting actual field conditions. This paper reports the effects of urea amended with triple superphosphate (TSP) and zeolite (Clinoptilolite) on soil pH, soil nitrate, soil exchangeable ammonium, dry matter production, N uptake, fresh cob production and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractPM Emissions in a Urban ContextEnrico Brizio, Giuseppe Genon, Stefania BorsarelliWithin a urban environment, three different sources of particulate matter should be considered: heating plants using different combustibles (natural gas, gas oil, fuel oil, wood), industrial plants placed in the surrounding area, traffic. While the effects of the first two origins can be easily calculated on the basis of existing emission factors, the PM emissions from traffic are of two … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions To The Study Of Heavy Metals Concentration Variation In Sedimentable Dusts According To The Distance From The Pollution SourceMariana DOBRA, Vasile VIMAN, Gheorghe VÂTCĂThe environment in areas where geological and mining activities, such as the extraction of ores containing heavy metals, take place, is heavily polluted with dusts resulting from these activities, as well as with residual waters from the mines. Depending on the meteorological conditions, as well as on the conditions under which sedimentable dusts or dusts in suspension are emitted into … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffectiveness of Ultrasound on the Destruction of E. coliMohammad H. DehghaniThe aim of this study was to investigate the impact of sonication as a disinfection method for determining the effectiveness of ultrasound waves on the inactivation of E. coli. Ultrasound waves at a frequency of 42 kHz were used to expose aqueous suspension of E. coli. Ultrasound waves display a strong influence on the rate of E. coli disruption in … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical Properties Analysis of Frictional Winding Mechanism with Bobbin Elastic SupportMohammed A. Alnawafleh, Faisal M. Al-GhathianA mathematical model of the Frictional Winding Mechanism (FWM) with bobbin elastic supports for a search of optimal structural and physical parameters for developing new and updating existing FWMs has been carried out. The model was derived from bobbin equipped with pendulum suspension for forming cylinder shaped packages. In the derivation method it was considered that the model corresponds the … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Growth Medium for Centella Asiatica Cell Culture Via Response Surface MethodologyRozita Omar, M. A. Abdullah, M. A. Hasan, M. MarziahThe effects of sucrose, Indole-3-Acetic Acid (IAA) and 6-BenzylAminoPurine (BAP) concentrations on cell growth of Centella asiatica cell suspension culture were studied. The concentrations were designed using Central-composite experimental design and regression analysis was carried out to obtain response surface model describing cell growth for prediction of optimum conditions.
