Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography. The molecular weight and monosaccharide composition of the isolated polysaccharides were analyzed using HPGPC and HPLC. The antioxidant activities of these tobacco polysaccharides were tested using DPPH, ABTS, hydroxyl radicals … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 15 Jan 2025 · 5,103 accessesView PDFCite

Research ArticleOpen accessIn the abstractPreliminary Study of Tomato Hybrids for Yield and Morphological Quality Attributes Under Khumaltar Condition, NepalSudip Devkota, Surendra Lal Shrestha, Amita PandeyAn experiment was conducted to evaluate tomato hybrids (Lycopersicon esculentum) for qualitative attributes of tomato fruits in Horticulture Research Division, Nepal Agriculture Research Council, Khumaltar, Lalitpur, Nepal. Fruits from newly developed eleven hybrids from council and an existing popular tomato hybrid, "Srijana" were selected to evaluate and characterize yield and quality attributes. In this study vegetative character, fruit quality parameters … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 20 Nov 2019 · 7,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of Biological Nitrogen Fixation in Critical Dryland PastureSyamsuddin Hasan, Budiman, Asmuddin Natsir et al.The aim of the study is to determine the production and growth of dwarf napier grass (Pennisetum purpureum cv.mott) integrated with siratro legumes (Macroptilium atropurpureum) contributing to the availability of preferred forage for ruminants on critical dryland. The study applied randomized block design consisted of 4 groups and 4 treatments; P0 consisted of 100% control Pennisetum purpureum cv.mott; P1 consisted … …OnLine Journal of Biological Sciences, Vol. 19, Issue 3 · 26 Jul 2019 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractModulation of Aging in Yeast Saccharomyces cerevisiae by Roselle Petal Extract (Hibiscus sabdariffa L.)Sarima, Rika Indri Astuti, Anja MeryandiniCellular aging drives diseases. Free radicals are called the main cause of cellular aging. Antioxidants can protect the body from free radical attack by reducing its negative effects. An antioxidant source can be obtained from plants, such as roselle (Hibiscus sabdariffa. L). This research was conducted to analyze the ability of roselle petals extract to increase the life span of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 6 Apr 2019 · 9,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow-Homology Protein Structural Class Prediction from Secondary Structure Based on Visibility and Horizontal Visibility NetworkZhi-Qin Zhao, Liang Luo, Xiao-Yan LiuIn this study, based on the predicted secondary structures of proteins, we propose a new approach to predict protein structural classes (α,β,α/β,α+β) for three widely used low-homology data sets. Fist, we obtain two time siries from the chaos game representation of each predicted secondary structure; second, based on two time series, we construct visibility and horizontal visibility network, respectively and … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 12 Mar 2018 · 9,668 accessesView PDFCite
