Research ArticleOpen accessIn the abstractDetermination of the Presence of Huanglongbing in Seeds and Movement of the Pathogen in Citrus reticulataHajivand Shokrollah, Thohirah Lee Abdullah, Kamaruzaman Sijam, Siti Nor Akmar AbdullahProblem statement: Huanglongbing (HLB) also known as citrus greening disease is a fastidious phloem-inhabiting bacterium in the genus Candidatus Liberibacter. Using universal primers, the 16S ribosomal DNA sequence of three strains of the bacterium were obtained by PCR. However there is very little information on seed transmission and HLB pathogen movement to find a way for control or reduce the … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,092 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEpitope 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 · 8,455 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiochemical and Genetic Responses of Fungi to the Toxic Effect of Synthetic and Natural FungicidesMarÍa-Elena Báez-Flores, Rosalba Troncoso-Rojas, Martin-Ernesto Tiznado-HernándezThe objective of the present review is to analyze the molecular basis of fungicide resistance mechanism to both synthetic fungicides and the natural fungicides isothiocyanates. The review is focused mainly on Alternaria sp., but whenever available, similar studies in other fungi have been included. Fungal resistant strains to dicarboximide and phenylpyrrole fungicides have been found to contain mutations in one … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,122 accessesView PDF Cite

Research ArticleOpen accessIn the abstractToll-Like Receptor (TLR) 2 and TLR4 Gene Expression in Canine HeartA. Linde, F. Blecha, T. MelgarejoToll-like receptors (TLRs) are archetypal pattern recognition receptors of immediate importance for an efficacious innate immune response. TLRs exhibit marked differential tissue activity and their levels within a discrete cell type can be highly dynamic. Of 13 known mammalian paralogues, three TLRs have been identified in the dog. Although cardiac TLR expression has been reported in other species, this study … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,924 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhylogeny and Molecular Study of Some Entomopathogenic Rhizobacteria Isolated from Two Regions in AlgeriaOulebsir-Mohandkaci Hakima, Benzina Farida, Khemili-Talbi Souad et al.The use of bacteria in the control of insect pests is a form of biological control whose practice is still not widespread. It is in this context that the present work falls. It concerns the isolation, characterization and identification of local bacterial strains for the purpose of their use in the control of certain pests. Indeed, 20 bacteria were isolated … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 2 Mar 2020 · 7,237 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGENE IMPRINTING: ENGRAVING THE PATHOGENESIS OF HERIDETARY DISEASESSandeep Satapathy, Roshan Kumar Singh, Harikrishnan RajendranGene imprinting has conduited the scope of our understanding of phenotypic expression and its corelation with constituent genotype. It is an epigenetic process that involves DNA methylation and histone modulation to attain monoallelic gene expression without altering the genetic sequences. A distinctive model of non-mendelian genetics, imprinting extends the control over expression of traits and selection of the allele that … …American Journal of Immunology, Vol. 10, Issue 1 · 12 Feb 2014 · 7,684 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMolecular Gender Determination of Ancient Human from Malay PeninsularZ.A. Shahrul Hisham, S. Sahidan, M. A.W. Rohaya et al.Problem statement: DNA samples from fourteen modern human bloods (seven males and seven females) and two ancient skeletal samples excavated from Kalumpang Island and Dungun, Peninsular Malaysia were subjected for molecular genders determination using specific primers of human AMELX and AMELY. Approach: A standard multiple PCR mixture with forward primer and either a human X-specific reverse primer for AMELX or … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 7,609 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCOMPARATIVE ANALYSIS OF INTER SIMPLE SEQUENCE REPEATS AND SIMPLE SEQUENCE REPEATS MARKERS: GENETIC ANALYSIS OF DESCHAMPSIA CESPITOSA POPULATIONS GROWING IN METAL CONTAMINATED REGIONS IN CANADAK.K. Nkongolo, S. Gervais, P. Michael, Y. ZhouComparative studies conducted on the genetic variation of metal-tolerant populations and their non-metal-tolerant counterparts have been performed on numerous species using isozyme markers. Analysis of genetic differences among plant populations growing in heavy metal-contaminated and uncontaminated regions are limited. The main objectives of the present study were to compare ISSR and microsatellite markers in assessing genetic variation in D. cespitosa … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 8 Apr 2014 · 7,291 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Sequence Based Validation of Gene Expression Microarray DataGerhard G. Thallinger, Eva Obermayr, Pornpimol Charoentong et al.Problem statement: Quantitative Reverse Transcription PCR (RT-qPCR) is often used to validate microarray data. Previous studies show different levels of correlation, without further investigation of influencing factors. Approach: We compared expression levels of 381 genes obtained from microarray hybridizations and from TaqMan based RT-qPCR assays. Correlation of expression levels was determined by comparing: (i) single genes across samples, (ii) all … …Current Research in Bioinformatics, Vol. 1, Issue 1 · 19 Jan 2012 · 13,722 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordGenetic Analysis of Bifidobacteriaceae in a Fermented Milk and Colostrum Product in Relation to Immune FunctionMarco RuggieroThis study investigates the microbial composition of a commercially available Swiss fermented milk and colostrum product with a history of use in chronic condition management since 2014.
