Research ArticleOpen accessPhrase in the titleSIR 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 PDFCite
Research ArticleOpen accessEvery word in the titleSignaling Pathways Involved In Dengue-2 Virus Infection Induced RANTES OverexpressionYing-Ray Lee, Huan-Yao Lei, Shun-Hua Chen et al.Dengue viruses participate in liver inflammation by inducting the expression of various chemokines including Regulated on Activation Normal T-cell Expressed and Secreted (RANTES). However, the underlying signaling remains unknown. Here, we reveal that Ras, Raf-1 and three mitogen-activated protein kinases (MAPKs) p38, extracellular signal-regulated kinase (Erk), and c-jun-NH2-terminal kinase (JNK) can be activated or phosphorylated in dengue-2 virus infected hepatocyte … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,173 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe 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 PDFCite
Research ArticleOpen accessEvery word in the titleEpitope Mapping of Dengue-Virus-Enhancing Monoclonal-Antibody Using Phage Display Peptide LibraryChung-I Rai, Huan-Yao Lei, Yee-Shin Lin et al.The Antibody-Dependent Enhancement (ADE) hypothesis has been proposed to explain why more severe manifestations of Dengue Hemorrhagic Fever and Dengue Shock Syndrome (DHF/DSS) occur predominantly during secondary infections of Dengue Virus (DV) with different serotypes. However, the epitopes recognized by these enhancing antibodies are unclear. Recently, antipre-M monoclonal antibody (mAb 70-21), which recognized all DV serotypes without neutralizing activity, were … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 8,453 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction of Immunologically Active Untagged Recombinant DENV-2 NS1 in Escherichia coliDessy Natalia, Christian Heryakusuma, Fernita Puspasari et al.Dengue is an infectious disease affecting 390 millions people in tropical and subtropical region annually. Dengue virus NS1 protein plays an important role in viral replication in the host cell and it is detected in high level in the infected patient serum. A synthetic gene of untagged DENV-2 NS1 with codons optimization for expression in Escherichia coli has been generated … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 10 Oct 2018 · 10,346 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCorrelation of IFN-Inducible Protein 10 Levels in Sera with Disease Severity and Clinical Outcome of the Dengue PatientsYing-Ray Lee, Nguyen-Thanh Hung, Ching-Chuan Liu et al.Dengue Virus (DV) infection may cause life-threatening Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Although many cytokines involved in the pathogenesis of DHF/DSS have been reported, the expression status of IFN-inducible protein-10 (IP-10) in dengue patients is still unknown. This is the first report to unravel that IP-10 level was significantly elevated in the sera of Dengue Fever … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,051 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImmunopathogenesis of Dengue Hemorrhagic FeverHuan-Yao Lei, Kao-Jean Huang, Yee-Shin Lin et al.Dengue virus infection causes Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) whose pathogeneses were not clearly understood. A new hypothesis of immunopathogenesis is proposed for the development of the DHF/DSS. An aberrant immune over-activation after dengue virus infection not only impair the immune response to clear the virus, but also result in overproduction of cytokines … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 14,762 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAspergillus Niger Metabolites Efficacies Against the Mosquito Larval (Culex Quinquefasciatus, Anopheles Stephensi and Aedes Aegypti) Population after Column ChromatographyNamita Soni, Soam PrakashProblem statement: Mosquito is a very common vector of several tropical diseases such as malaria, filariasis, dengue and chikungunya. Till todate, many xenobiotics have been used to control mosquito population and protect people from mosquito born diseases but increasing rate of resistance against these xenobiotics is a major concern in the disease control management. In contrast, extensive use of these … …Current Research in Microbiology, Vol. 2, Issue 1 · 21 Dec 2011 · 15,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcalcitonin and Clinical Factors Associated with Severe Dengue Infection in Hospitalized Adults in MalaysiaHuzairi Sani, Nada Syazana, Zahir Izuan et al.Dengue Fever (DF) is the commonest mosquito-borne viral infection that results in hospitalisation amongst patients in Malaysia. The cornerstone of managing dengue virus infection is the prediction hence prevention of severe DF from developing. Warning signs proposed by WHO as clinical predictors of severe DF are insensitive. Procalcitonin (PCT) has been shown to increase in bacterial infections and is useful … …American Journal of Infectious Diseases, Vol. 15, Issue 4 · 3 Dec 2019 · 7,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractLyapunov Function for a Dengue Transmission Model where two Species of Mosquitoes are Present: Global StabilityI Ming Tang, Rattiya Sungchasit, Puntani PongsumpunIn this study, we are interested in the newly observed endemic due to the ZIKA virus. In the absence of a full knowledge of the dynamics of the infection due to this virus, we consider a model of the closely related dengue virus when there are two species of mosquitoes, A. aegypti and A. albopictus mosquitoes who are both capable … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 25 Oct 2017 · 8,274 accessesView PDFCite
