Research ArticleOpen accessIn the abstractInfluence of Decreasing Temperature on Soil Microbial Activity in a Boreal Shield EcozoneAlistar Moy, Kabwe NkongoloAlthough the focus on warming is imperative to address climate change, addressing the effects of cooling is arguably just as relevant in characterizing the enzyme response to temperature fluctuations. In this study, the response of enzyme activity to diminishing temperatures in the field was evaluated. The targeted sites were located in the City of Greater Sudbury in Northern Ontario, Canada. … …American Journal of Environmental Sciences, Vol. 18, Issue 2 · 17 Apr 2022 · 6,665 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Humic Acid Dosage and Fermentation Time with Bacillus subtilis on Nutrient Content and Quality of Palm Kernel CakeMirnawati, Gita Ciptaan, Yoga Seftiadi, Malik MakmurThis study aims to determine the effects of humic acid dosage and fermentation time with Bacillus subtilis on the nutrient content and quality of Palm Kernel Cake (PKC). A Completely Randomized Design (CRD) with a 3 × 4 factorial pattern and 3 replications was applied. The present experiment considered two major parameters, termed A and B. Factor A represents the … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 15 Feb 2022 · 6,702 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn Silico Cholinesterase and Monoamine Oxidase Inhibitory Activities of Perillaldehyde and D-Limonene, Main Compounds of Essential Oil of Algerian Ammodaucus leucotrichusNesrine Sadaoui-Smadhi, Souad Khemili-Talbi, Wadood Abdul et al.In a continuation of our previous work for the exploration of novel enzyme inhibitors, molecular modeling was used to inspect the binding mode of perillaldehyde and D-limonene, the major compounds of essential oil of Algerian Ammodaucus leucotrichus into the active site pocket of cholinesterase (AChE and BuChE) and Monoamine Oxidase (MAO). The molecular docking was carried out using Molecular Operating … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 28 Feb 2020 · 7,317 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGadolinium at Low Concentration Suppresses both Osteoclastic and Osteoblastic Activities in the Scales of GoldfishNobuo Suzuki, Kazuki Watanabe, Aika Sekimoto et al.For determining the effect of environmental pollutants on fish bone metabolism, we have developed an in vitro bioassay system using teleost scales that has osteoclasts, osteoblasts and bone matrix as markers: alkaline phosphatase (ALP) for osteoblasts and tartrate-resistant acid phosphatase (TRAP) for osteoclasts. Using this bioassay, the influence of gadolinium (Gd) on osteoclasts and osteoblasts of goldfish scales was examined … …American Journal of Environmental Sciences, Vol. 15, Issue 4 · 20 Sep 2019 · 8,457 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction, Extraction and Characterization of Lipases from the Antarctic Yeast Guehomyces pullulansLuis Lascano-Demera, Patricia Portero Barahona, Enrique Javier Carvajal BarrigaThe production of extracellular lipases from the Antarctic yeast Guehomyces pullulans is induced using an olive oil medium as an inductor substrate and a first characterization of its enzyme, using the protein extract obtained from the medium, is described. For this, the effect of pH and temperature on the lipase activity are evaluated and the enzyme kinetic for the lipase … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 11 Apr 2019 · 10,031 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtilization of Banana, Pineapple and Watermelon Wastes-Substrate: As Consortiums to Remediating Cyanide Polluted SoilFlorence Obiageli Nduka, Samuel Chibuike Ubani, Victor Eshu Okpashi et al.The act of processing cassava for varied food products has come with unguided and wide-spread contamination of cyanide in the environment. The need for effective reduction in cost to enable remediation of cyanide-contaminated sites from cassava mill factories is the purpose of this investigation. This involves bio-stimulation of organic wastes with indigenous microorganisms to degrade cyanide. The application of organic … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Apr 2018 · 9,934 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSerum Ornithine Carbamoyltransferase Activity and Correlation with Fatty Liver in Dairy Cows with Displaced AbomasumKen Onda, Reiichiro Sato, Yosuke Sasaki et al.Ornithine Carbamoyltransferase (OCT) is a hepatocyte-specific enzyme; elevated serum activity indicates liver damage. Displaced abomasum frequently occurs around the time of parturition in dairy cattle and is associated with fatty liver. We analyzed serum OCT activities to investigate the relationship between displaced abomasum and fatty liver. Lactating Holstein cows, 75 clinically healthy and 22 with displaced abomasum, were used. Serum … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 3 · 13 Jul 2016 · 7,662 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Cement Dust on the Physiological Activities of Arabidopsis thalianaSaeid Abu-Romman, Jarrah AlzubiAir pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation, lipid per oxidation … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 17 Nov 2015 · 8,117 accessesView PDF Cite

CULTIVARSZeinab A. Salama, El-Zanaty A.A. Abou El-Nour, Mohamed M. El Fouly, Alaa A. GaafarA water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 16 May 2014 · 7,906 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCELL DETACHMENT BY PROLYL-SPECIFIC ENDOPEPTIDASE FROM WOLFIPORIA COCOSNicole Mika, Katharina Cierpka, Michaela C. Lange et al.As requirements for Advanced Therapy Medicinal Product (ATMP) production differ from other production processes (e.g., therapeutic protein production), cell detachment is often a crucial step for the process success. In most cases, cell detachment is done enzymatically. Although many peptidases are established in cell culture in R&D, e.g., Trypsin as gold standard, many of them seem to be unsuitable in … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 8 Feb 2014 · 8,159 accessesView PDF Cite
