Research ArticleOpen accessIn the author namesApplication of Optimal Control to the Epidemiology of Fowl Pox Transmission Dynamics in PoultryUdofia Ekere Sunday, Inyama Simeon ChiomaProblem statement: In this study, we present the mathematical model of the transmission dynamics of fowl pox infection in poultry. Approach: It describes the interaction between the susceptible and the infected birds which results in a system of ordinary differential equation. Introducing the control which represents the effort in applying chemoprophylaxis control u1 and treatment control u2 in birds with … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 13 Jun 2012 · 6,957 accessesView PDFCite
Research ArticleOpen accessIn the author namesLevels 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 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the author namesUrine Turbidity and Microhaematuria as Rapid Assessment Indicators for Schistosoma haematobium Infection among School Children in Endemic AreasHassan Adesola, Ntiaidem Uduak, Morenikeji Olajumoke et al.Problem statement: Urinary schistosomiasis is highly endemic in Nigeria and for effective control measure, an efficient, quick and yet cheap diagnosis should be integrated. This will ensure the proper management of infection due to Schistosoma haematobium in low resource communities of Nigeria. Approach: This cross-sectional study recruited a total of 456 (252 males, 204 females) school children aged 3-20 years … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 21 Mar 2012 · 9,099 accessesView PDFCite
Research ArticleOpen accessIn the author namesToxicity evaluation of yoyo 'cleanser' bitters and fields Swedish bitters herbal preparations following sub-chronic administration in ratsMartins Ekor, Odusoga Adewale Osonuga, Adesina Olalekan Odewabi et al.Problem statement: Owing to numerous adverse effects of most orthodox pharmaceuticals, the use of herbal remedies in treatment and prevention of diseases is gaining much attention, especially in developing countries. The increase patronage of these remedies is often predicated on the assumption that they are harmless since they are prepared from natural sources. However, toxicity related to herbal medicines is … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 4 · 13 Jun 2011 · 10,205 accessesView PDFCite
