Research ArticleOpen accessEvery word in the titleReflectivity of Reflectarrays Based on Dielectric SubstratesM. Y. Ismail, M. Inam, A. M.A. ZaidiProblem statement: Reflectarrays provide a low cost and low profile solution for antennas required for high gain applications but their use is restricted in some applications due to the narrow bandwidth and high loss performance. These performance limitations can be attributed to different sources of reflectivity of the reflectarrays. This work provides a thorough investigation on the reflectivity performance of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,628 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Endoribonuclease Domain of IRE1 and its Substrate HAC1 are Structurally Linked Components of the Unfolded Protein Response in FungiLuis David Maldonado-BonillaThe unfolded protein response sustains the folding capacity of the endoplasmic reticulum under conditions that increase the activity of the secretory pathway. In fungi, the unfolded protein response exclusively depends on the kinase/endoribonuclease IRE1, which senses the accumulation of unfolded proteins in the endoplasmic reticulum lumen and catalyzes the committed step in the unconventional splicing of HAC1 mRNA that encodes … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 14 Oct 2020 · 6,541 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCellulolytic Enzymes Production by Solid State Culture Using Pecan Nut Shell as Substrate and SupportMiguel A. Medina-Morales, José L. Martínez-Hernández, Heliodoro de la Garza, Cristóbal Noé AguilarProblem Statement: Great interest in the use of lignocellulosic biomass is increasing in order to diminish the accumulation of residues, such as pecan nut shells. One of the alternatives is the fungal degradation of these residues. Approach: The capacity of Trichoderma (coded as T1, T2 and T3) strains to produce cellulase and xylonite was evaluated. Results: Pecan nut shell fibers … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,023 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInhibition of Sphingolipid Biosynthesis in Cultured Cells Enhances the Oligosaccharide Production from Exogenous Artifical SubstrateTomohisa Kato, Maria Carmelita Z. Kasuya, Kenichi HatanakaThe effect of fumonisin B1 which is an inhibitor of ceramide synthesis on saccharide elongation of dodecyl β-lactoside (Lac-C12), which is the analogue of lactosyl ceramide (LacCer), in mouse melanoma B16 cells and African green-monkey kidney (Vero) cells was examined. By adding fumonisin B1 in the culture medium used for glycosylation of Lac-C12, mouse melanoma B16 cells synthesized GM3-type analogue … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,669 accessesView PDFCite
