Research ArticleOpen accessIn the abstractBioaugmentative Approaches for Dairy Wastewater TreatmentIrina Schneider, Yana TopalovaProblem statement: The achievement of a good ecological status of water receivers after discharge of waste or partially treated water from dairy industry requires harmonic interaction between water treatment technology and self-purification processes. Approach: The present research included two modules. First: an anaerobic treatment process for dairy wastewater in broadly spread sequencing batch bioreactor with fixed biomass was studied. As … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 8,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractGlomalin Production and Microbial Activity in Soils Impacted by Gypsum Mining in a Brazilian Semiarid AreaAdalia Cavalcanti do Espírito Santo Mergulhao, Helio Almeida Burity, Fabio Sérgio Barbosa da Silva et al.Problem statement: Mining activities involve the removal of the vegetal cover and the soil organic layer, causing a severe environmental impact. In Northeast Brazil, 40% of the world’s crude gypsum is found in a semiarid area, making this region responsible for 95% of the gypsum demand in the national market. Although economically important, this activity is harmful to the environment. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 11 Nov 2010 · 9,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensity Functional Theory Based Quantitative Structure Activity Relationship Study of 2,5-Bis(1-Aziridinyl)-p-Benzoquinones with Lymphoid LeukemiaBahjat A. Saeed, Rita S. EliasProblem statement: QSAR techniques increase the probability of success and reduce time and coast in drug discovery process. The study presented QSAR investigation on 32 bioactive aziridinylbenzoquinones that have activity against lymphoid leukemia. Approach: Molecular descriptors, molecular weight, total energy, hardness, chemical potential, electrophilicity index, HOMO and LUMO energies were calculated. Initial geometry optimizations were carried out with the AM1 … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntitumor and Quantitative Structure Activity Relationship Study for Dihydropyridones Derived from CurcuminBahjat A. Saeed, Kawkab Y. Saour, Rita S. Elias et al.Problem statement: Pyridones are known to have variety of biological activities like antitumor, antibacterial, antiinflamatory and antimalarial activities. This study presented antitumor evaluation of dihydropyridones derived from curcumin, as well as curcumin for comparison. Approach: The compounds evaluated for a preliminary estimation of the in vitro tumor inhibiting activity against 11 of tumor cell lines by using Microculture Tetrazolium assay … …American Journal of Immunology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Polyoxypregnane Glycoside from the Roots of Dregea volubilis (L.f) Benth. ex Hook. f and its Chondroprotective EffectSaksri Sanyacharernkul, Akanit Itghiarbha, Prachya Kongtawelert et al.Problem statement: Dregea genus (Asclepiadaceae) is well known for the rich of steroid pregnane contents and these plants are famous for the potential to be applied as alternative biological activities. Dregea volubilis is the only species of Dregea genus in Thailand. The chemical and biological investigations of this plant are interesting to bioassay-guided fractionation, particularly chondroprotective effect.
