APRIORI ALGORITHM APPROACH FOR AUTOMATIC TEXT PROCESSING AND GENERIC-BASED SUMMARIZATION SYSTEM

Text Processing has always existed in various forms. It makes voluminous text easily digestible, offers brief and quick overview of the subject contents and may provide critical context analysis to the reader. With the growth of digital articles in forms of news, blogs, wikis etc., there is serious need for a text processor which can adequately summarized an article or documents for the reader. This redirected and takes away the effort needed to read, assimilate and create summaries manually. This research paper proposed a system which provides unique opportunity for developing a core set text summarization system using Apriori Algorithm techniques to perform Binary Associated Rule on Data Mining. The system makes available a means of storing the automatic Generic-based summaries for future references and requirements

Genotoxicity evaluation of Chlorfenapyr in exposed freshwater African catfish Clarias gariepinus using micronucleus test

Chlorfenapyr is a new formulated insecticide targeted against insecticide resistant species. Its application in targeting harmful aquatic insects may potentially contaminate aquatic environment. This study is to evaluate its genotoxic effects on non-targeted aquatic biota. The study assessed the genotoxic potentials of chlorfenapyr in African catfish (Clarias gariepinus) using the micronucleus (MN) test. Juvenile stage of C. gariepinus were exposed to different concentrations; 5.00 – 15.00 mgL-1 of chlorfenapyr for 96 hours, peripheral blood was collected through the caudal vein and examined for micronucleus induction in the erythrocytes. The tested concentrations of chlorfenapyr did not elicit significant [F (5, 18) = 0.167, p 0.971] increase in MN formation and other nuclear abnormalities in the peripheral erythrocytes of C. gariepinus. The outcome of this study gives credence to the view that chlorfenapyr is not clastogenic and or aneugenic to non-targeted aquatic vertebrate with reference to fish (C. gariepinus)

The total antioxidant content of more than 3100 foods, beverages, spices, herbs and supplements used worldwide

Background: A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies. Methods: We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name) were registered for each individual food sample and constitute the Antioxidant Food Table. Results: The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values. Conclusions: This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non-plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies. The present antioxidant database is therefore an essential research tool to further elucidate the potential health effects of phytochemical antioxidants in diet

Metagenomics: an emerging tool for the chemistry of environmental remediation

Metagenomics is the study of genetic information, including the sequences and genomes of microorganisms present in an environment. Since 1998, the full-scale application of this technique to environmental chemistry has brought significant advances in the characterization of the nature and chemical composition/distribution of contaminants present in environmental matrices of contaminated and/or remediated sites. This has been critical in the selection of microorganisms and has contributed significantly to the success of this biological treatment over the years. Metagenomics has gone through different phases of development, which ranges from initial sequencing strategies to next-generation sequencing (NGS), which is a recently developed technology to obtain more robust deoxyribonucleic acid (DNA) profile of microorganisms devoid of chimeric sequences which reduces the quality of metagenomic data. Therefore, the objective of this review is to evaluate the applications of metagenomics in the understanding of environmental dynamics of chemical contaminants during remediation studies. Also, this review presents the relationship between biological characteristics of microorganisms and chemical properties of chemical compounds, which forms the basis of bioremediation and could be useful in developing predictive models that could enhance remediation efficiency. In conclusion, metagenomic techniques have improved the characterisation of chemical contaminants in the environment and provides a correlation for useful prediction of the type of contaminant expected in various environmental matrices

Haematological effect of chlorfenapyr-exposed freshwater African mud catfish, Clarias gariepinus (Burchell 1822)

The effects of chlorfenapyr pesticide were investigated on juvenile of Clarias gariepinus. Sub-lethal test was carried out using 5, 7, 9, 11 and 15 mgL-1 of chlorfenapyr pesticide for 96 hours, and peripheral blood was collected through the caudal vein and examined for haematological changes. There was significant reduction (P0.05) in WBC when compared to the control. RBC increase was directly proportional to increase in chlorfenapyr dose and significantly differed from control (p0.05). HGB increased in a dose-dependent manner. MCV values of all treatment groups, except 15 mgL-1, were higher when compared to control. MCH was not significantly different from control. PLT decreased with increase in concentration and was lower for all treatment when compared with control. Results obtained in this study suggest that exposure to sub-lethal concentrations of chlorfenapyr can alter the haematological indices of non-target organisms
