Research ArticleOpen accessIn the abstractA Comparative Analysis on the Physiological Effects of the Physical and Chemical Properties of the Trihalomethanes on Nutrient Levels, Oxidative Stress and Sterol Compositions of Leaf Oils in Solanum Lycopersicum CultivarsBabatunde C. Akande, Olalekan S. Fatoki, James P. Odendaal et al.Trihalomethane group of disinfection by-products was used to evaluate the magnitude of physiological changes induced on nutrient levels, oxidative stress and phytosterol content in two tomato cultivars. The tomato cultivars were grown as potted plants in a greenhouse and exposed to the varying concentrations of trihalomethanes and organochlorines via irrigation water for a period of 30 days. The concentration levels … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 11 May 2018 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractExpression of Metallothionein-Like Protein 2B Gene Induced by Different Concentrations of Copper in White Spruce (Picea glauca)Megan McKergow, Kabwe NkongoloThe alterations to the expressions of metal transporter genes can induce metal ion uptake to maintain cell homeostasis when metal concentrations are low. Metallothioneins (MTs) are a class of low molecular mass (4-8 kDa), cysteine (Cys)-rich proteins that can bind metals via the thiol groups of their Cys residues. Studies on MT gene expressions in higher plants, such as conifers, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 25 Dec 2022 · 5,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Household Wastes in D.R. Congo, a Case Study of LubumbashiMartin T. Mpinda, Sissou Zakari, Olusegun K. Abass et al.The insufficient supervision of household solid waste is a notorious problem in DR. Congo cities. Besides, solid waste management in Lubumbashi has been very rudimentary and unsystematic. This study aims to quantify and characterize the household solid waste in two Lubumbashi municipalities. For more than 50 years after independence from colonialism, the city trailed direct discharge of waste on exposed … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 10 Jun 2017 · 8,217 accessesView PDFCite
Research ArticleOpen accessIn the abstractEXPOSURE TO “TEXTISMS” DOES NOT LOWER SPELLING SCORES FOR ELEMENTARY SCHOOL AGED CHILDRENHolly Anderson, Robert J.F. Elsner“Textisms” are semi-standardized abbreviations and conventions uses in SMS text messaging. Students in the fourth and fifth grades (N = 136) were exposed to words on a spelling list as correctly-spelled words, incorrectly-spelled words, or “textisms” to determine whether short term exposure to “textisms” decreased spelling performance for elementary aged children. Multivariate ANOVA found exposure type significantly impacted post-exposure spelling, … …Current Research in Psychology, Vol. 5, Issue 2 · 10 Dec 2014 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn-Vivo Evaluation of Hexavalent Chromium Induced DNA Damage by Alkaline Comet Assay and Oxidative Stress in Catla catlaKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Jaya Krishna KuruvaIn the present study, the acute toxicity of Chromium in fingerlings of Catla catla, an Indian major carp, was evaluated with renewal bioassay method. In vivo studies were designed to assess the extent of Micronucleus Assay, Comet Assay under the exposure of common heavy-metal compounds, namely, Chromium Nitrate, using Catla catla (2n = 20), as a test model. The laboratory … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolymorphisms in the 5’ Flanking Region and First Exon of Insulin-Like Growth Factor 1 Gene in Southern Populations of BuffaloSaber Khederzadeh, Ahmad YazdanpanahThe Insulin-like Growth Factor 1 (IGF-1) system plays a critical endocrine role controlling nutrient metabolism in animals and it is a group of structurally-related polypeptides that regulate the growth of many types of mammalian cells. In liver, IGF-1 is dynamically regulated by lactation and energy balance. Less is known about the regulation of IGF-1 and IGF-binding protein mRNA in reproductive … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 6,846 accessesView PDFCite

Research ArticleOpen accessIn the abstractLevels of Dichlorodiphenyltrichloroethane and its Metabolites in the Blood of Agrochemicals RetailersAnthony J. Hotton, Jeoffrey T. Barminas, Sunday A. OsemeahonProblem statement: In tropical countries like Nigeria, the storage, sales and handling of pesticide by agrochemical retailers in indoor stores located in open markets and residential areas were fraught with problem of undesirable side effect. Serum levels of 1, 1, 1-trichloro-2, 2-di (4-chlorophenyl) ethane (DDT) and its metabolite were measured among agrochemicals retailers in Taraba, Nigeria. Approach: Blood samples from … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 22 Mar 2012 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Storing Temperature on Hepatotoxicity and Nephrotoxicity of Ifosfamide in Female RatFalah Mohammed AzizProblem statement: Ifosfamide (IFO) is a cytotoxic alkylating drug used for the treatment of a variety of cancers, although it has been found to induce certain hematological, hepatotoxic and nephrotoxic side effects. This drug is widely used in developing country, especially Iraq, but without caring too much to the storing temperature due to low drug maintaining facilities.
