Research ArticleOpen accessEvery word in the titleBioactivity of Sumac (Rhus Coriaria) Extract as a Green Alternative for Plant Pathogen InhibitionMohammed H. Al-Mamoori, Meisam Zargar, Elena N. Pakina, Fatih DadaşoğluEnvironmental stress caused by pathogenic fungi leads to considerable losses in global crop productivity. Plant-derived extracts are eco-friendly and sustainable alternatives that can inhibit biotic stresses. Sumac (Rhus coriaria) is widely used in industrial and medicinal applications due to its extract rich in secondary metabolites, similar to those found in chemical pesticides and pharmaceuticals. This study aimed to characterize the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Nov 2025 · 2,209 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Bioactivity of Fucoxanthin from Undaria pinnatifida in VitroYiting Li, Ye Liu, Yuepeng Wang et al.Fucoxanthin, a marine carotenoid, can be found in marine algae and some marine invertebrates, has remarkable biological properties for human health. It is known that fucoxanthin has anti-cancer activity on some human cancer cells such as human colon cancers, leukemia cells, prostate cancer cells, breast cancer cells. In this study, the fucoxanthin was extracted from Undaria pinnatifida, after purification by … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 7 Jun 2016 · 7,866 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysiological Active Substance Changes of Soybean Curd Residue Fermented by Preussia aemulans and its BioactivityYiting Li, Shili Meng, Min Shi, Zhenya ZhangA new species of fungus Preussia aemulans isolated from the Cordyceps sinensis fruiting body was cultured by soybean curd residue using solid-state fermentation method. The content of polysaccharide, amino acid, protein, phenolics and nucleoside were massively improved under the optimum conditions, including 10% adding dosage of glucose, 3% adding dosage of beef extract, 15 days of fermentation time. The crude … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 6 Jan 2016 · 7,453 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBioactivity of the Alkaloids, Norharman and L-N-Methylcrotonosine/LinearisineMargelette Ellis-Tabanor, Dwight Robinson, Eric HyslopThe toxic effects of the alkaloids, Norharman and a mixture of L-N-Methylcrotonosine/Linearisine (M/L mixture), on two organisms, Gambusia puncticulata and Veronicella sloanei were determined. The effect of the alkaloids on the fecundity of Thiara granifera was also investigated. Norharman was harmless to G. puncticulata but the M/L mixture inflicted 55.5% mortality on fish populations. The alkaloids had narcotizing, repellent and … …OnLine Journal of Biological Sciences, Vol. 15, Issue 1 · 11 Apr 2015 · 7,202 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSurface Bioactivity of Sol Gel Derived 3Y-TZP Bioinert Ceramic through Hydroxylation Technique Using 5M H3PO4R. Velmurugan, S. Kanagesan, S. Jesurani, T. KalaivaniProblem statement: This study presented bone like apatite formation on yttria stabilized zirconia in Simulated Body Fluid (SBF) through hydroxylation technique. Approach: Sol gel route was used to prepare yttria stabilized zirconia. Then it was hydroxylated with 5M H3PO4 for formation of Zr-OH group. Moreover, the growth rate of calcium and phosphate on zirconia substrate was examined using simulated body … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExocellular (1→6)-β-D-Glucan (Lasiodiplodan): Carboxymethylation, Thermal Behavior, Antioxidant and Antimicrobial ActivityThais Vanessa Theis, Gabrielle Cristina Calegari, Vidiany Aparecida Queiroz Santos et al.β-Glucans are biomacromolecules of industrial interest for its biological and technological properties, including ability to modify the rheology of food systems and different biological functionalities. In this study, lasiodiplodan an exocellular polysaccharide of the (1→6)-β-D-glucan type produced by the fungus Lasiodiplodia theobromae MMPI was obtained in a bench-scale bioreactor operated in discontinuous mode. Lasiodiplodan produced was derivatized by carboxymethylation and … …American Journal of Immunology, Vol. 13, Issue 1 · 29 Mar 2017 · 8,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of a Cyclachaena Xanthiifolia Extract on Trematodes Opisthorchis Felineus: An in Vitro StudyDenis Ponomarev, Elena Khramova, Natalia Gubanova et al.Cyclachaena xanthiifolia is a phytochemically rich invasive weed with documented allelopathic properties, making it a candidate source of bioactive compounds with potential medicinal applications. This study investigated the anthelmintic activity of a crude aqueous-ethanolic extract of C. xanthiifolia (CxEt), prepared from equal proportions of leaves and seeds, against the trematode Opisthorchis felineus in vitro. The effects of CxEt on the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytochemical Composition, Antibacterial, and Antioxidant Properties of Foeniculum vulgare Essential OilSaif M. Dmour, Saqr Abushattal, Sultan Ayesh Mohammed Saghir et al.This study intended to inspect the phytochemical composition and bioactivity of Fennel (Foeniculum vulgare) Seed Essential Oil (FSEO) from Jordan. The EO was extracted via hydrodistillation from air-dried samples with 4.42% (v/w) yield. Twenty compounds, constituting around 98.5% of the EO were identified using Gas Chromatography-Mass Spectrometry (GC-MS). Estragole (47.15%) and Anethole (36.2%), appeared as predominant oxygenated monoterpenes compounds in … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 1 Aug 2025 · 4,638 accessesView PDFCite
