Research ArticleOpen accessIn the abstractSpirulina protects against cadmium-induced hepatotoxicity in ratsAmr Amin, Alaaeldin A. Hamza, Sayel Daoud, Waleed HamzaCadmium (Cd) is an environmental and industrial cumulative pollutant that most affects many organs specially the liver. The protective effect of Spirulina, filamentous blue green algae, on Cd – induced oxidative stress and hepatotoxicity was evaluated in male rats. Oral administration of water extract of Spirulina for seven days followed by an acute toxic dose of Cd (3.5 mg kg … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 2 · 30 Jun 2006 · 11,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model for Bioaccumulation of Metals in Crassostrea virginica from Apalachicola Bay, FloridaDennis A. Apeti, Elijah Johnson, Larry RobinsonKinetics of bioaccumulation of the trace metals (Cd and Zn) by C. virginica were investigated in this study. A computer program, Oyster Bioaccumulation Model (OBM), was developed to simulate the accumulation of the metals from both dissolved (water column) and particulate (food) phases by C. virginica. The model is based on two main attributes: (1) the oyster biological characteristics such … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrogen Peroxide Biosensor Based on the Direct Electrochemistry of Myoglobin Immobilized in Poly-3-Hydroxybutyrate FilmXiang Ma, Rongwu Yang, Genxi LiDirect electrochemistry of myoglobin (Mb) was observed in a stable film composed of a natural lipid polymer (poly-3-hydroxybutyrate) and Mb, the film of which was modified on a pyrolytic graphite electrode. The apparent formal potential of Mb was at about -260 mV in an acetate buffer solution with pH 5.0. Moreover, Mb in the polymer film exhibited catalytic activity towards … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant, Free Radical Scavenging and Metal Chelating Characteristics of PropolisHikmet Geckil, Burhan Ates, Gokhan Durmaz et al.This study was undertaken to determine the reducing characteristics, metal chelating capability, anti-lipid peroxidative and antiradical properties of propolis compared to two widely used artificial antioxidants, Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT). The water and ethanol extracts of propolis showed significantly a different degree of metal chelating, radical scavenging activity and reducing power. In general, ethanol extracts of propolis … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 9,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,091 accessesView PDFCite
