Research ArticleOpen accessIn the abstractDifferential Gene Transcription in Red Oak (Quercus rubra) Genotypes Resistant to Copper ToxicityProulx Migueal, Paul Michael, Charnelle Djeukam, Kabwe NkongoloToxicity of metals is a major abiotic stressor of plants. Copper (Cu) is one of the most abundant metals in soils from the Greater Sudbury Region (GSR) due to its mining history. Recent studies have described several transporters and chelating proteins involved in copper resistance. Quercus rubra (Red Oak) is a common species that grows in metal contaminated soils in … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 11 Dec 2017 · 8,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Bioactivity of Fucoxanthin from Undaria pinnatifida in VitroYiting Li, Ye Liu, Yuepeng Wang et al.Fucoxanthin, a marine carotenoid, can be found in marine algae and some marine invertebrates, has remarkable biological properties for human health. It is known that fucoxanthin has anti-cancer activity on some human cancer cells such as human colon cancers, leukemia cells, prostate cancer cells, breast cancer cells. In this study, the fucoxanthin was extracted from Undaria pinnatifida, after purification by … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 7 Jun 2016 · 7,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Biological Evaluation of 6-Hydroxy-4-Methyl-5,7-(Bis-p-ChlorophenylAzo) CoumarinDalal M. Ibrahim, Juliana Jumal, Farah Wahida Harun6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarinhas been synthesized and characterizedby CHN elemental analysis, FTIR, 1H-NMR-spectroscopy andmass-spectral data. Cytotoxic screening by MTT assay was carried out on the compoundagainst breast cancer cells. The overall results from preliminary screeningprogram revealed that the cell proliferation was highly inhibited by 6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarin with the value of 2.81%, at concentration of 30 µg mL-1 comparedwith the untreated control cells and also … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 21 Dec 2015 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMPARISON OF EDTA AND EDDS ENHANCTED PHYTOEXTRACTION OF Cr AND Pb FROM CONTAMINATED SOIL BY ANANAS COMOSUS (L.) MERR.Pantawat Sampanpanish, Tippawan PojanapornThe effects of chelating agents on Chromium (Cr) and lead (Pb) absorption were studied by planting pineapple, Ananas comosus (L.) Merr. in contaminated soil. All plant samples were grown in a nursery for 30 days and then separated into seven sets: Set (1) had nothing added (Blank); (2) had Pb added as Pb(II) Nitrate (Pb(NO3)2) at 500 mg kg-1 soil; … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Apr 2014 · 7,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractCYCLIC CHOLECYSTOKININ ANALOGUES EXHIBIT HIGH BLOOD STABILITY AND BINDING AFFINITY WITH CHOLECYSTOKININ RECEPTOREun-Ha Joh, Jae Cheong Lim, Jin Joo Kim et al.Recently, incidence of Cholecystokinin (CCK) receptor is recognized as a factor that determines the aggressive phenotype of pancreatic cancer. In this study, a novel Cholecystokinin (CCK) analogues; DOTA-Nle-cyclo (Glu-Trp-Met-Asp-Phe-Lys-NH2) (DOTA-cCCK) and DOTA-Nle-cyclo (Glu-Trp-Nle-Asp-Phe-Lys-NH2) (DOTA-[Nle]-cCCK) were synthesized and radiolabeled and the targeting abilities on the CCK receptor were evaluated for new CCK receptor targeting agents searching. Peptides were prepared through a … …OnLine Journal of Biological Sciences, Vol. 14, Issue 1 · 2 Jan 2014 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Extraction of Pectic and Polyphenols from Mexican Lime Pomace and BagasseDaniela Sanchez-Aldana, Cristobal Noe Aguilar, Guadalupe Virginia Nevarez-Moorillon, Juan Carlos Contreras EsquivelMexican lime bagasse and pomace are rich in pectin and they also represent an important source of value-added compounds such as polyphenols. Two different options for the combined recovery of pectin and phenolic compounds from Mexican lime bagasse and pomace, two byproducts of industrial lime processing, were developed. Conventional and microwave-assisted extraction methods were used. All pectic extracts presented a … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 29 Oct 2013 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombined Chelation Therapy with Deferasirox and Desferrioxamine In Removing Lead from RatsFaezeh Dahooee Balooch, Seyed Jamilaldin Fatemi, Marzieh Iranmanesh, Batool HosseinkhaniThe present study aimed to evaluate the potential efficiency of Deferasirox (DFX) and Desfferioxamine (DFO) as chelating agents in removing lead from rats as a biological model. Two different doses of lead (II) chloride (40 and 80 mg kg-1 body weight) were used for 45 days.
