Results higher than the MBD and MPD, respectively. Chi-square test, Fisher exact test, Mann-Whitney U test, and logistic regression were performed to assess associations between different serotypes and dengue severity, while considering gender and age. Subsequently, the dengue serotype and genotype data were statistically analyzed for 101 of 120 corresponding patientsâ clinical manifestations to generate a descriptive relation between the genetic components and clinical outcomes of dengue infected patients. Dengue serotype-speciï¬c diï¬erences in clinical manifestation, labora-, tory parameters and risk of severe disease in adults, Singapore. Interestingly, the scientific proofs of the usage of bezoar were limited. The EA fraction of H. cordata inhibited viral infectivity up to 6 d. Cinanserin hydrochloride was able to inhibit MHV for only 2 d. The 50% inhibitory concentrations (IC50) of the EA fraction of H. cordata added before the viral adsorption stage were 0.98 Î¼g/mL for MHV and 7.50 Î¼g/mL for DENV-2 with absence of cytotoxicity. The compounds in H. cordata contribute to the superior antiviral efficacy of the EA fraction which lacked cytotoxicity in vitro and acute toxicity in vivo. copy and thermogravimetric analysis of tannins and tannic acid. The spectra represent the average of 15 scans, llustration of the distinct functional group in tannic acid detected by FTIR analysis. Our ï¬ndings revealed that all the extracts of porcupine dates exhibited antiviral activity against DENV-2 in, of 11 Âµg/mL) than methanol crude extracts, This study suggests that porcupine dates possess antiviral properties against DENV-2, which is attrib-. Dengue fever is the most prevalent mosquito-bor, viral disease with high morbidity and mortality that is, currently endemic in more than 100 countries within, tropical and subtropical regions worldwide [. To ascertain this, virus attachment, assay was conducted and conï¬rmed that the porcupine, dates extracts inhibited the DENV-2 infection by block, ing virus attachment to the host cells. Our Core Strength is in the Application of Asian Traditional Medical Philosophy to Assist Our Clients Gain and Protect Health Vitality, and Quality of Life.

Geneva: World Health Organization; ï¬avivirus life cycle. However, the synergistic efficacy of the flavonoid combination was still less than that of the EA fraction. Moreover, results from time-of-addition study showed that the inhibitory effect of CBX on DENV was exhibited by targeting the virus itself, not the host cells. îen, three col, the tannins bound to Sephadex LH-20 beads which were, then collected as tannins fraction (sample of BDTF or, PDTF). îis study, for the ï¬rst, time, provides the scientiï¬c evidence on the anti-DENV, property of the porcupine dates as well as its mode of, more in-depth nuclear magnetic resonance (NMR) analy, sis of the chemical content of porcupine dates was also, Raw material of porcupine dates, BD and PD obtained, from a local Chinese medicinal shop were ï¬nely ground, using pestle and mortar. They were although pragmatic in their economic policy focus, they did not adopt any common model or blueprint policy rather their strategies were followed by their specific strength, weakness and goals. Data were statistically analysed using ordinary one-way ANOVA followed by Dunnettâ, used in this study was isolated from a patient with severe, dengue, it is highly likely that the DENV-2 strain was less, îe antiviral activity ascribed to the interaction, between the extracts and host cells was also investi, gated; pre-treating the cells with BDTF prevented the, DENV-2 infection by at least 75% and similar result was, due to the presence of speciï¬c chemical structure in the, FT tannic acid that is similar to the one in BDTF, be implied that the tannins in porcupine dates might, DENV-2 attachment to the host cells, preventing the ini, ST and FT tannic acids, in which only 9.8% of virus inhi, virus inhibition by FT. îis might be attributed to the, diï¬erences in the chemical composition between ST and, porcupine dates could be the key compounds that con, tribute to the antiviral eï¬ect of porcupine dates extracts, against DENV-2 infection. Porcupine bezoar was found in the gastrointestinal tract of porcupine and made up of indigestible plant matters. In, contrast, the antiviral activity of the pre-treatment with, MPD or ST showed only 8.0â9.8% of inhibition and there, the infectivity of DENV-2, which is similar to the previ, results suggest that the tannins in BDTF and PDTF could. The increasing interest of the individuals in this industry is that the major reason for the expansion of this market”.
