Research ArticleOpen accessIn the abstractWeissella cibaria Fungistatic Activity against Fusarium spp. affecting Yellow PitahayaLeidy Johana Valencia-Hernández, Karina López-López, Liliana Serna-CockFungistatic activity of a Lactic-Acid Bacteria (LAB) was assessed in vitro while isolated from its rumen fluid, against Fusarium oxysporum and Fusarium fujikoroi, basal-rot related species in yellow pitahaya. Fed batch was used to reproduce said LAB. Fungistatic activity kinetic tests were performed on the ferment (S1) and on two of the fractions obtained through centrifugation, supernatant (S2) and biomass … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 10 Dec 2016 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiation-Induced Cognitive Dysfunction After Different Schemes of Fractionated Whole Brain IrradiationZorkina Yana Alexandrovna, Zubkov Eugene Andreevich, Yusubalieva Gaukhar Maratovna et al.Radiation-induced cognitive dysfunction is a serious complication of radiation therapy. In humans, numerous cases of radiation damage have been recorded after irradiation for therapeutic purposes. The degree of cognitive dysfunctions and its dependence on biological effective doses should be tested in animal preclinical models to minimize radiation side effects. Fractionated whole brain irradiation was performed according to the following schemes: … …Neuroscience International, Vol. 5, Issue 2 · 14 Jan 2015 · 7,256 accessesView PDFCite

Research ArticleOpen accessIn the abstractComparative Physiological and Molecular Study of Some Sheep Breeds in Saudi ArabiaMohammad S. AL-Harbi, Hamed S. Alwagdany, Sayed A.M. AmerNaemi, Heri, Najdi and Sawakni sheep breeds inhabiting Kingdom of Saudi Arabia were studied on both physiological and molecular bases. Native polyacrylamide gel-electrophoreses for two enzymes Malate Dehydrogenase (Mdh) and Malic Enzyme (Me) recorded 5 isoenzyme loci from which 4 were polymorphic and 1 was monomorphic. Mdh showed three fractions, the first was recorded in Sawakni and Najdi breeds, the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeciation and Availability of Cr, Ni and Co IN Serpentine Soils of Ranau, SabahMahsa Tashakor, Wan Zuhairi Wan Yaacob, Hamzah MohamadProblem statement: Serpentine soils are known as a geogenic source of heavy metal pollution because they are anomalously rich in chromium, nickel and cobalt. Approach: However, only that portion of these metals which is available in the ecosystem and incorporates in the bio-transformation processes, is dangerous for the environment. Availability of Cr, Ni and Co depends on their speciation into … …Current Research in Geoscience, Vol. 2, Issue 1 · 20 Mar 2013 · 13,551 accessesView PDFCite
