Research ArticleOpen accessIn the abstractMathematical Analysis of the Non Linear Epidemic ModelLaid Chahrazed-Rahmani Fouad LazharClassical epidemic models assume that the size of the total population is constant. More recent models consider a population size variable to take into account a longer period with death and disease causing reduced reproductive. The model contains a disease-free equilibrium and one or multiple equilibria are endemic. The stability of a disease-free status equilibrium and the existence of other … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 19 Jun 2012 · 7,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling the Dynamics of Tuberculosis Transmission in Children and AdultsF. Nyabadza, M. KgosimoreProblem statement: The fight Against Tuberculosis (TB) has mainly focused on the adult population because children were perceived to pose a very low risk in TB transmission. This assumption ignores the potential risk children had as reservoirs of latent infections from which future cases evolve when they become adults. It was therefore important to investigate the dynamics of TB taking … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 5 Jun 2012 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mosquito Repellent on the Transmission Model of Chikungunya FeverSurapol Naowarat, Prasit Thongjaem, I. Ming TangProblem statement: In 2008 there was a large outbreak of Chikungunya fever in southern Thailand. Chikungunya fever is an emerging disease which tends to affect rubber plantation and fruit orchard workers more than other occupation. This study we considers the efficacy of using mosquito repellent as a way to prevent and control the spread of Chikungunya fever. The mathematical model … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 14 Feb 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical Model for Determining Human Susceptibility to Dengue FeverSurapol Naowarat, Thanon Korkiatsakul, I. Ming TangProblem statement: Mathematical models are a useful tool for understanding and describing the transmission of diseases such as dengue fever, one of the most prevalently emerging diseases common to tropical and subtropical areas throughout South East Asia. By taking into account human susceptibility to disease, the dynamics of a dengue disease model is proposed. Approach: Using standard methods for analyzing … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 28 Sep 2011 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model to Simulate Tuberculosis Disease Population DynamicsO.K. Koriko, T.T. YusufA mathematical model to depict Tuberculosis disease population dynamics was presented. The model population was compartmentalised as appropriate and the resulting model equations were solved numerically while different instances of the disease transmission were simulated. The graphical profiles of the various sub-populations with time were presented and discussed based on the results from our simulations. Also, the disease-free and endemic … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,623 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-Dimensional Model for the Transmission Dynamics of Schistosomiasis in the Human-Snail HostsG. Besigye-BafakiThe modes of transmission of schistosomiasis are considered. The transmission model is developed with an aim of establishing possible endemic equilibria within the community. Analysis of the model reveals that if the recovery rate β of human infectives and the death rate of snails δ are increased and if at the same time the contact rate κ of the human … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 6,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics of Infected Snails and Mated Schistosoma Worms within the Human HostG. Besigye-Bafaki, L. S. LuboobiMale and female worms are independently distributed within a human host each with a Poisson probability distribution mass function. Mating takes place immediately when partners are available. It was found that the mated worm function is non-linear near the origin and becomes almost linear as the worms increase. They increase with increase in the worm load due to aggregation of … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractApoptosis Inducer Capacity of Cardiotonic Steroids of Urginea maritima Extract on SH-SY5Y Neuroblastoma Cells, with Less Susceptibility among Neuron-Module CellsMaati M. Elghuol, Khalilah Abdul Khalil, Mazatulikhma Mat Zain, Mohamed Saifulaman Mohamed SaidNatural products have played a significant role in conventional treatment and in the development of new drugs for a wide range of illnesses, including malignant disease. Urginea maritima is classified as an herb is endemic to the Mediterranean area. This herb was renowned in traditional ethnopharmacological applications. Notwithstanding, there is a lack of evidence pertaining to the characterization of the … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 28 May 2016 · 7,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitric Oxide Donors with Therapeutic Strategic in Experimental Schistossomiasis MansoniWander Rogério Pavanelli, Jean Jerley Nogueira da Silva, Carolina Panis et al.Schistosomiasis, an immune disease, remains a major public health problem in endemic area. To determine the influence of Nitric Oxide (NO) on this disease, we tested two compounds (Trans-[Ru(bpy)2(NO)SO3](PF6)-PF6 and Na2[Fe(CN)5(NO)]-SNP, which releases NO when activated by biological reducing agents, in BALB/c mice infected subcutaneously by Schistosoma BH strains. The parasitic activity of NO-donors was evaluated in this model by … …American Journal of Immunology, Vol. 10, Issue 4 · 24 Feb 2015 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview of Malaria ControlEmmanuel Chanda, Mulakwa Kamuliwo, Richard W. Steketee et al.Malaria remains a serious global public health problem and a leading cause of morbidity and mortality in sub Saharan Africa. In Zambia the disease is endemic with stable transmission, accounting for 40% of all out-patient attendances and is responsible for 20% deaths among children under five. Scaling up of scientifically proven high impact preventive, curative and supportive interventions and deploying … …Current Research in Medicine, Vol. 4, Issue 1 · 29 Apr 2013 · 7,960 accessesView PDFCite
