One gram of samples were then extracted using 50 mL (1:50 w/v) of 100% methanol and shaken at 200 rpm using orbital shaker (Protech Model 719) for 1 h at room temperature. new ed. Methods: Viral factors, such as dengue serotype and genotype, are the components of interest in this study. copy and thermogravimetric analysis of tannins and tannic acid. An equal volume of various concentrations of extracts or, tannic acids serially diluted in fourfold starting at non-, toxic concentration were incubated with 30 foci-forming, µL of extract-virus mixture was inoculated on Vero cells, tion, the inoculums were replaced by 2% CMC overlay, medium. The bigger porcupine bezoar, also known as porcupine stone or porcupine date, demonstrates better quality and higher medicinal value. Our findings revealed that all the extracts of porcupine dates exhibited antiviral activity against DENV-2 in Vero cells. Regarding overall samples, 77.3 % were caused by DENV-1, 16.1 % by DENV-4, 6.4 % by DENV-2, and 0.2 % by DENV-3. PLoS Negl T, gue viremia titer, antibody response pattern, and virus serotype correlate. Meanwhile, patients with DENV 2 infection showed significant warning signs and developed severe dengue (p = 0.007). and 2.287 mg ml−1, respectively. Broad-spectrum antiviral activity of chebulagic acid and, punicalagin against viruses that use glycosaminoglycans for entry. (Saururaceae) and three of its constituent flavonoids (quercetin, quercitrin and rutin) against murine coronavirus and dengue virus (DENV). The purpose of this study is to better understand the impacts of … Dengue fever is currently endemic in tropical and subtropical countries worldwide and effective drug. The frequencies of the positive photopatch test reactions were 2-hydroxy-4-methoxybenzophenone (oxybenzone) (n = 6), 2-hydroxymethoxymethylbenzophenone (mexenone) (n = 3), 2-ethylhexyl-4-dimethylaminobenzoate (n = 1), ketoprofen gel (n = 1) and the patient's own product (n = 9). Levels of porcupine poaching aren’t known, despite urgent calls for research into the problem from organizations such as Traffic, the Environmental Investigation Agency, a … There were 20 positive photopatch test reactions found in these 10 patients, and all 20 positive reactions were of current relevance. In recent years, India has reported increased incidences of concurrent infection with multiple serotypes of dengue viruses (DENV). SSH and YYL conceived the study. The Porcupine Abyssal Plain is vast plain situated at a water depth between 4000 and 4850 m. This site has been studied from the surface to the abyss since the mid-1980s. Moreover, the, results of the virucidal and attachment assays correlated, well with each other in term of antiviral effect, in which, the porcupine dates extracts particularly the tannin frac, tions exerted the greatest antiviral activity against DENV-, 2. Trichobezoars are … Lyophilized samples were dissolved in deuterated DMSO at 10 mg/mL. How, ever, some minor differences in the spectra such as 1121, mercial tannic acid standard. lection, analysis, and interpretation of data and in the writing the manuscript. In: Pinto CA, editor. Moreover, distinct composition and classification of plant materials found in the phytobezoars and their potential benefits in cancer treatment are also discussed. BDTF and PDTF also exerted a similar higher virucidal effect (IC50 of 11 µg/mL) than methanol crude extracts (IC50 ≈ 52-66 µg/mL). as there was a lack of dose–response effect for MBD. The widespread use of the bezoar as an alternative medicine for treatment of deadly illnesses in Malaysia was passed down from generations of the multi-diverse ethnicity environment that existed here. Dengue fever is currently endemic in tropical and subtropical countries worldwide and effective drug against DENV infection is still unavailable. As illustrated in, MBD and MPD exhibited similar lower antiviral activ, respectively, and a selectivity index (SI) of more than, 2 when compared to both BDTF and PDTF (Fig., was not in a dose-dependent manner, thus the, MBD may not be accurate. Efficacy of a tetravalent dengue vaccine in. Twenty-two patients were included. from generations of the multi-diverse ethnicity environment that existed here. DENV-1 genotype 1 and DENV-2 cosmopolitan were the predominant genotypes identified.
