Research ArticleOpen accessIn the abstractDietary Inclusion of Sunflower Seed Alters Blood Plasma and Endometrium Lipid Profile in Beef CowsMariângela Bueno Cordeiro Maldonado, Ricardo de Oliveira Rodrigues, Dante Pazzanese Duarte Lanna et al.Polyunsaturated Fatty Acids (PUFA)-enriched diets are recognized as a significant approach for improving the reproductive efficiency of cattle. The aim of this study was to evaluate the effects of sunflower seed, a PUFA-rich feed source, supplementation on plasma and endometrium lipid profiles in beef cattle. It was hypothesized that feeding of sunflower seed has an additional effect on PUFA that … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 2 · 25 Jul 2023 · 5,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Anatomical Characteristics and Phytochemical Components Between Two Species of Hedysarum (Fabaceae)Adil Kusmangazinov, Meruyert Sakenovna Kurmanbayeva, Irina Zharkova et al.Hedysarum L. is one of the large genus of the Fabaceae Lindl. family, consisting of 200 species. Species in the genus Hedysarum are valuable forage and medicinal resources. In this study, we studied Hedysarum theinum Krasnob and Hedysarum neglectum Ledeb growing in the western Altai of Eastern Kazakhstan. H. theinum is a perennial, herbaceous, valuable medicinal plant, a rare species, … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 14 Jun 2023 · 5,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Characterization of Phosphate Solubilizing Activity of Endophytic Fungi from Zingiberaceous SpeciesErman Munir, Yurnaliza, Anisa Lutfia, Adrian HartantoPhosphorus (P), which is one of the less available soil macronutrients, is important for plant growth and metabolism. A promising strategy to increase the P uptake by plants is by introducing Phosphate-Solubilizing Microorganisms (PSM) into the P-deficient regions, to convert P into soluble forms through organic acids secreted by the PSMs. The aim of this study was to characterize the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 27 Mar 2022 · 6,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Milk Fatty Acids Health Index as Milk Value Added Determinant using FT-NIRSDespal Despal, Dwitamy Anzhany, Idat Galih Permana et al.The current milk price system based on Total Plate Count (TPC) and Total Solids (TS) are less sensitive in determining milk quality. Milk fatty acids profiles reflected milk quality for human health. However, their determination using Gas Chromatography (GC) is impracticable to be included as a daily price decision determinant. The study aimed to find a model for milk value … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 23 Dec 2021 · 6,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction Optimization of Essential Oil from Medicago hispida and Preliminary Inhibitory Mechanism Against Escherichia coliXiulan Chu, Qianfeng Chen, Tong Wang et al.In this study, the extraction optimization, characterization, antioxidant evaluation and preliminary inhibitory mechanism against Escherichia coli of the essential oil from dried Medicago hispida (EOMH) were explored to uncover the pending questions that had been raised in our previous work and to enlarge the industrial potential of EOMH production. The optimal parameters for EOMH extraction were: Extraction time of 7 … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 5,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Constituents and Bacteriostatic Activity of Essential Oil Extracted from Sea Buckthorn Seeds by Different MethodsHepeng Zhao, Fuyin Zhao, Qian Xiao et al.Sea buckthorn is a homologous plant listed in Chinese pharmacopoeia. The Essential Oils (EOs) of Sea Buckthorn Seeds (SBTS) are widely used in medicine and health products in China, Russia and other countries. The extraction methods of SBTS with advantages of low cost, high yield and high activity have attracted considerable attention. In this study, the extraction rate, chemical compositions … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 4 Jun 2021 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractEssential Oils from The Dropped Flowers of Camellia japonica: Extraction Optimization, Chemical Profile and Antibacterial PropertyYunqi Kong, Gaochao Wang, Xinyu Wang et al.Camellia japonica is one of the most economically valuable species that can be taxonomically placed in the Theaceae family. Many horticultural varieties of C. japonica have been cultivated as ornamental trees worldwide, owing to their charming flowers. However, young C. japonica flowers usually drop in a “decapitated” form during the peak flowering stage, causing a resource waste. In this study, … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 27 Jan 2021 · 6,985 accessesView PDFCite
Research NotesOpen accessIn the abstractThe Phytol-rich Essential Oil from Fresh Medicago hispida Exerts Significant Inhibitory Activity against Escherichia coliLixue Zheng, Leijie Ben, Zhumei Cui et al.Medicago hispida is one of the most widely distributed and commonly cultivated plants of the genus Medicago in China. It is mainly consumed as a vegetable. In this paper, the extraction, chemical composition and antimicrobial potential of the essential oil from fresh M. hispida (EOFMH) were conducted and evaluated for the first time. The extraction yield of EOFMH was found … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 28 Dec 2019 · 7,355 accessesView PDFCite
