Correlating biochemical and chemical oxygen demand of effluents – A case study of selected industries in Kumasi, Ghana
FK Attiogbe, M Glover-Amengor, KT Nyadziehe
West African Journal of Applied Ecology , 2007,
Abstract: The study aims at establishing an empirical correlation between biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) of effluents from selected industries in the Kumasi Metropolis to facilitate speedy effluent quality assessment or optimal process control. Hourly effluent samples were collected for an 8-h period three times per week for analysis of the principal parameters BOD5 and COD, using the Standard Methods for the Examination of Water and Wastewater. Measured BOD5 and COD of the effluents were above the required discharged guideline of 50 mg/l and 250 mg/l, respectively, specified by the Environmental Protection Agency, Ghana. These levels of BOD5 and COD of the wastewaters could pose potential pollution to the waterbodies in which they are discharged since untreated. Results also indicate that the degree of common variation between the two variables COD and BOD5 is highly positive for the effluents from Ghana Brewery Limited (GBL), Guinness Ghana Limited GGL) and Coca-Cola Bottling Company of Ghana (Coca-Cola), thus, the variables are correlated. However, the degree of common variation between the variables was low for the effluent from the Kumasi Abattoir. The fitted equations were GBL, y = 0.6558x – 270, r = 0.93; Coca-Cola, y = 0.3536x + 113.6, r = 0.81; GGL, y = 0.225x + 1343.7, r = 0.83; Kumasi Abattoir, y = 0.1331x + 54806, r = 0.22) with x and y representing COD and BOD5, respectively. The BOD5/COD ratio for the wastewater from the selected industries can also be approximated to the gradient of their respective fitted equations, i.e. GBL, 0.66; Coca-Cola, 0.35; GGL, 0.23. The fitted equations for GBL, Coca-Cola and GGL can be used to facilitate rapid effluent assessment or optimal process control by these industries once the chemical oxygen demand is measured.
TNF and anti-TNF agents in Beh?et's disease

Arthritis Research & Therapy , 2003, DOI: 10.1186/ar981
Abstract: Hassard (2001) reported rapid and dramatic improvement in gastrointestinal and extraintestinal symptoms and findings of the disorder after treatment with infliximab. Similar response was seen in two other patients treated by Travis (2001). This experience was followed by the report of Robertson (2001) of a patient free of oral and genital ulcerations for the first time in 10 years after three infusions of infliximab. Remission of mucocutaneous symptoms for one year followed two infusions of infliximab in a patient previously uncontrolled by multiple immunosuppressive agents (Goossens, 2001). Mucocutaneous lesions remitted with infliximab in a patient with Beh?et's disease associated with rheumatoid arthritis (Rozenbaum, 2002). At EULAR 2002, Turkish investigators reported the results of the first double-masked, placebo-controlled study (n = 40) of anti-TNF therapy with etanercept in mucocutaneous Beh?et's disease (Melikoglu, 2002). This agent suppressed disease manifestations with resurgence after the drug was discontinued. Additional recent reports of anti-TNF therapies in Beh?et's disease were presented at several international meetings.The experience with anti-TNF-α treatments for the ocular manifestations of Beh?et's disease has been growing and very positive. Sfikakis (2001) reported the benefits of infliximab in five patients with panuveitis in Beh?et's disease. This included two patients treated with infliximab therapy without an increase in conventional treatment. At the ACR meeting in 2002 these Greek investigators reported successful monotherapy with infliximab in acute ocular inflammation in Beh?et's disease in 14 patients. The authors suggested that the dramatic and rapid response in these patients would favor the use of this agent over conventional therapy. Positive responses to anti-TNF agents in ocular Beh?et's disease have been documented in numerous case reports in the literature or presentations at international meetings.Significant differences exi
Interactions of viruses in Cowpea: effects on growth and yield parameters
KT Kareem, MA Taiwo
Virology Journal , 2007, DOI: 10.1186/1743-422x-4-15
Abstract: Cowpea is an annual tropical grain legume, which plays an important role in the nutrition of people in developing countries of the tropics and subtropics, especially in sub-Saharan Africa, Asia Central and South America. Due to its high protein content (20 – 25%), cowpea has been referred to as "poor man's meat". It is very palatable, highly nutritious and relatively free of metabolites or other toxins [1,2].Cowpeas are susceptible to a wide range of pests and pathogens that attack the crop at all stages of growth [3]. These include insects, bacteria, fungi and viruses. Estimated losses due to virus infection have been variously put at between 10 and 100% [4,5], depending on the virus-host-vector relationships as well as the prevailing epidemiological factors. Host- plant resistance is currently the most effective method for the control of cowpea virus diseases in Africa. Thus, an adequate knowledge of the viruses and the strains occurring in the main cowpea-growing areas of Africa is a pre-requisite for effective control [6].Out of more than 20 viruses reported on cowpea from different parts of the world [7-9] nine are known to infect the crop naturally in Nigeria [10-12]. They include the following viruses: Cowpea aphid-borne mosaic virus (CABMV), genus Potyvirus, Cowpea yellow mosaic virus (CPMV), genus Comovirus, Southern bean mosaic virus (SBMV), genus Sobemovirus, Cowpea mottle virus (CMeV), genus Carmovirus, Cowpea golden mosaic virus (CPGMV), genus Bigeminivirus, Cucumber mosaic virus (CMV), genus Cucumovirus, Cowpea mild mottle virus (CPMMV), genus Carlavirus, Sunn-hemp mosaic virus (SHMV), genus Tobamovirus and Blackeye mosaic virus (BICMV), genus Potyvirus. On the basis of geographical distribution, pathogenic variability and yield losses, CABMV, CPMV and occasionally SBMV are the most important viruses in Nigeria. CMeV, CPGMV and CMV are of localized importance while CPMMV and SHMV are not important. BICMV has a low rate of occurrence. Separation and ide

Evaluation of Solid Waste Generation, Categories and Disposal Options in Developing Countries: A Case Study of Nigeria
JO Babayemi, KT Dauda
Journal of Applied Sciences and Environmental Management , 2009,
Abstract: The quantity and generation rate of solid wastes in Nigeria have increased at an alarming rate over the years with lack of efficient and modern technology for the management of the wastes. The generation rate, collection and disposal of solid wastes are functions of several factors which if well considered and appropriated could bring the desired solution to the waste management problems in Nigeria. The quantity and rate of solid waste generation in several cities in Nigeria, factors influencing the generation, solid waste types and categories, collection, disposal, reuse and recycling, and environmental problems were investigated in this study. The results indicated large generation at high rate without a corresponding efficient technology to manage the wastes. Of 201 respondents to questionnaire in Abeokuta, 35.8% used waste collection services, 64.2% used other waste disposal options, 16.4% used both, 68.7% and 58.7% were aware of waste collection service and waste management regulations, respectively; while 28.4% separated their solid wastes at source
The temptation of Realpolitik and vox populi in the ecclesiology of the Emerging Apostolic Churches with special reference to the fivefold ministry
KT Resane, J Buitendag
HTS Theological Studies/Teologiese Studies , 2008,
Abstract: The Emerging Apostolic Churches do not have a uniform church polity since the power of governance is claimed to be with the fivefold ministers, while at the same time embracing either the Episcopal, Presbyterial, or Congregational church governments. The fivefold ministry is a generally accepted term that refers to the five ministries given by Christ to the Church to stand in unique spiritual offices, as found in Ephesians 4:11. This article tries to answer the question: “Are the Emerging Apostolic Churches ecclesiologically correct by centring the authority of governance in the fivefold ministers and the popular voices of the followers?” At the same time it is endeavored to argue that due to Biblical and theological grounds the fivefold ministry is untenable to church polity hence Realpolitik and vox populi dominating the ecclesiastical life and polity of the Emerging Apostolic Churches. The aim is to demonstrate that these two concepts (Realpolitik and vox populi) play a significant part in shaping the church polity and structures of this ecclesiastical phenomenon.

Hypoglycemic Effect of Methanolic Extract of Anacardium occidentale leaves in Alloxan-Induced Diabetic Rats
TR Fagbohun, KT Odufunwa
Nigerian Journal of Physiological Sciences , 2010,
Abstract: Anacardium occidentale Leave (Anacardiaceae), a plant natively grown in wastelands in Africa is used as a folk remedy for diabetes mellitus. Previous studies, reported the hypoglycemic effect of the aqueous leaf extract of A. occidentale in diabetic rats and its prophylactic activity against the diabetogenic action of streptozotocin This study evaluated the hypoglycemic effect of a methanolic extract of streptozotocin leaves and its fractions in Alloxan-induced diabetic rats in comparison to Tolbutamide, a reference drug. For moderately diabetic rat, A. occidentale caused a 79.2 % change over 4 hours and Tolbutamide caused a 63.1 % change over this same time period. When the rat were considered to be severely diabetic, the A. occidentale decreased the blood glucose levels by 20.8% change over four hours and the mean percent change over 4 hours for Tolbutamide was 47.63 %. These values were not considered significant (p>0.05). So the same conclusion can be made about the efficacy of A. occidentale, when compared to the reference drug, Tolbutamide. These results that show that A. occidentale has a similar ability compared with Tolbutamide to lower blood glucose levels.

Journal of Analytical Methods in Chemistry , 2009, DOI: 10.1155/2009/502527
Abstract: Designing new medical drugs for a specific disease requires extensive analysis of many molecules that have an activity for the disease. The main goal of these extensive analyses is to discover substructures (fragments) that account for the activity of these molecules. Once they are discovered, these fragments are used to understand the structure of new drugs and design new medicines for the disease. In this paper, we propose an interactive approach for visual molecule mining to discover fragments of molecules that are responsible for the desired activity with respect to a specific disease. Our approach visualizes molecular data in a form that can be interpreted by a human expert. Using a pipelining structure, it enables experts to contribute to the solution with their expertise at different levels. In order to derive desired fragments, it combines histogram-based filtering and clustering methods in a novel way. This combination enables a flexible determination of frequent fragments that repeat in molecules exactly or with some variations.
In vitro genotoxicity of piperacillin impurity-A
M Vijayan, M Deecaraman, KT Pudupalayam
African Journal of Biotechnology , 2007,
Abstract: The manufacturing and storage of the piperacillin produce different impurities of various concentrations, which may influence the efficacy and safety of the drug. Since no report of genotoxicity data is available on the impurities of piperacillin, further studies were designed and conducted to provide information for establishing the safety profile and qualification of the piperacillin impurity-A. Salmonella typhimurium strains were exposed to Piperacillin impurity-A for Ames tests. Neither increase in number of revertants indicative of mutagenic activity nor inhibition of bacterial growth, indicative of cytotoxicity were observed up to 5 mg/plate both in the presence and absence of metabolic activation. Similarly, chromosomal aberration assay did not reveal any significant alterations up to 5 mg/culture as compared to the negative control both in the presence and absence of metabolic activation (S9 mix). The results of these studies indicate that Piperacillin impurity-A is non-mutagenic in Ames test and non-clastogenic in chromosomal aberration study.
