The enzyme is able to break down organic molecules made of amino acids, known as polypeptides and thus … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 44,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical Studies of Lipase from Germinating Oil Seeds (Glycine max)P. P. Gadge, S. D. Madhikar, J. N. Yewle et al.Problem statement: Lipase is one of the important enzymes in food, pharmaceutical, detergent and biofuels industries. Search for the lipase with distinct features, possibly from germinating seeds, is of interest for industrial applications. Approach: The lipase produced by soybean oil seeds was partially purified and characterized in terms of the optimal pH and temperature for activity as well as substrate … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 19 Jan 2012 · 9,703 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepatoprotective Effect of Taurine Against Oxidative Stress Due to Methotrexate in RatE. Issabeagloo, M. Taghizadiyeh, P. KermanizadehProblem statement: Taurine, 2-aminoethanesulphonic acid is an essential amino acid. It is present at high concentrations in many tissues. It plays important roles in numerous physiological functions including conjugation with bile acids, modulation of calcium levels and maintenance of osmolarity, antioxidation and stabilization of membranes. Methotrexate (MTX), as the most disease modifying anti-rheumatic drug used for Rheumatoid Arthritis (RA), has … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 16 Jan 2012 · 8,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeat Spoilage Mechanisms and Preservation Techniques: A Critical ReviewD. Dave, Abdel E. GhalyProblem statement: Extremely perishable meat provides favorable growth condition for various microorganisms. Meat is also very much susceptible to spoilage due to chemical and enzymatic activities. The breakdown of fat, protein and carbohydrates of meat results in the development of off-odors, off-flavor and slim formation which make the meat objectionable for human consumption. It is, therefore, necessary to control meat … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 2 Nov 2011 · 54,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanisms of Anti-Cancer Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Vernonia amygdalina (V. amygdalina) has been shown to have cancer cell inhibition and cytotoxic effects. Approach: This study discusses the multi-faceted and multi-linked mechanisms by which cancer tissue inhibition and destruction is achieved by V. amygdalina leaf extract and powder (subsequently called V. amygdalina Extract). Cancer cell inhibition by V. amygdalina is suggested to occur through inhibition of … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 26 Oct 2011 · 9,090 accessesView PDFCite
