Through the examination and evaluation of expedition data, along with comprehensive research and literature analysis, the study successfully identified species that have experienced a reduction in their distribution … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 18 Aug 2023 · 5,515 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe SEIR Dynamical Transmission Model of Dengue Disease with and Without the Vertical Transmission of the VirusPratchaya Chanprasopchai, I. Ming Tang, Puntani PongsumpunThe transmission of dengue disease when there is a possibility of Vertical Transmission (VT) is studied using mathematical modeling. In the normal case, the mosquito is infected by the dengue virus when it bites an infectious human being. Evidence is gathering that the mosquitoes can also be infected through sexual contact with infected male mosquito. To see the possible consequence … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 2 Jan 2018 · 9,057 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMalaria and Climate Change: Discussion on Economic ImpactsMd. Shahin Mia, Rawshan Ara Begum, Ah-Choy Er et al.Problem statement: Climate change is a global environmental change that is adversely affecting human health by causing various health impacts in countries throughout the world. Climate is the most influential driving force of vector-borne diseases such as malaria. Changes in climate factors substantially affect reproduction, development, distribution and seasonal transmissions of malaria. Climate change increases the outbreak of malaria which … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,584 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA 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 PDF Cite

Research ArticleOpen accessIn the keywordsSIR Transmission Model of Dengue Virus Taking Into Account Two Species of Mosquitoes and an Age Structure in the Human PopulationR. Sungchasit, P. Pongsumpun, I. M. TangDengue is a vector-borne disease. It is transmitted to humans by the bites of the Aedes aegypti and Aedes albopictus mosquitoes. The human population is separated into two classes, a child class and an adult class, each class being described by a SIR model. The transmission rates of the two mosquito species are different and depend on what class the … …American Journal of Applied Sciences, Vol. 12, Issue 6 · 28 Jul 2015 · 6,511 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGlobal Analysis of an Epidemic Model with Non-Linear Incidence RateS. A.A. El-Marouf, S. M. AlihabyProblem statement: In this study the equilibrium points and their local stability are found for SIQ and SIQR epidemic models with three forms of the incidence rates. Also, we study the global stability of the equilibrium by constructing the new forms of Liapounov functions. Conclusion/Recommendations: We explored the existence of Hopf bifurcation for some parameters in the given model. …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,274 accessesView PDF Cite

Case ReportOpen accessIn the abstractBeyond Occam’s Razor: Diffuse Large B-Cell Lymphoma With Concurrent Acid-Fast Bacilli Positivity–A Case ReportOm Sharma, Shaurya Gupta, Prasan Kumar PandaIn tuberculosis-endemic regions, necrotizing lymphadenitis with Acid-Fast Bacilli (AFB) is often presumed to indicate tuberculous etiology, but this assumption may lead to misdiagnosis when immunophenotypic evaluation is not performed. In this report, we present the case of an immunocompetent elderly man who presented with prolonged high-grade fever, progressive abdominal distension, and stable cervical and submandibular lymphadenopathy. He had been empirically … …American Journal of Infectious Diseases, Vol. 22, Issue 1 · 24 Jul 2026 · 1,236 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeed Treatment-Based Biocontrol of Tomato Damping off Using Plant Essential Oil and Green Silver NanoparticlesLaila Reklaoui, Zine El Abidine Bzazou Elouazzani, El Touhami Tayebi Ouazzani et al.The fungal pathogen Rhizoctonia solani is a major causal agent of damping-off in tomato plants, leading to severe yield losses worldwide. Conventional fungicides, while effective, raise concerns regarding environmental safety and human health, highlighting the urgent need for sustainable alternatives. In this study, we report for the first time the use of Origanum compactum essential oil to biosynthesize silver nanoparticles … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 2 Jun 2026 · 1,298 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDengue Fever Prediction Empowered by Radial Basis Function Networks, Dynamic Mode Decomposition, and Learning-Based Foraging AlgorithmArchana T, Faritha Banu JDengue fever is presently considered a major health threat that must be addressed. External and internal factors that induce nonlinear oscillations in the occurrence of dengue disease have made optimal resource allocation stimulating. Public health initiatives aimed at eradicating this vector use accurate and timely data through field processes. In dengue-endemic nations, early dengue prediction remains a main concern for … …Journal of Computer Science, Vol. 22, Issue 4 · 16 Apr 2026 · 1,496 accessesView PDF Cite
