Research NotesOpen accessEvery word in the titleHistopathological Characterization and Expression of Vitamin D Receptor in the Prostate of Healthy Dogs and Dogs with Prostatic CarcinomaAkiko Ikeda, Masanori Kobayashi, Tatsuya Hori et al.Vitamin D Receptor (VDR) expression is implicated in human Prostatic Carcinoma (PC), but its role in canine PC is unclear. To investigate how VDR expression is affected by age and castration in healthy dogs and how it changes with PC, we evaluated prostates from 8-month-old (n = 5) or 6-year-old (n = 8) intact males, 1-8-year-old healthy castrated males (n … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 24 Feb 2023 · 5,295 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation, Characterization and Antioxidant Activity of a Novel Acetylated Polysaccharide from Flammulina VelutipesYingyun Peng, Han Jiang, Yufeng Wu et al.In this study, a novel polysaccharide FVP2a wasextracted and purified from F. velutipes. Ac-FVP2a was prepared bychemical acetylation. The preparation process of Ac-FVP2a was optimized usingthe response surface method based on three experimental factors includingreaction time, reaction temperature, and the ratio of FVP2a to aceticanhydride. The physicochemical characteristics andantioxidant activities of Ac-FVP2a in vitro were investigated. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,212 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasound-Assisted Enzymatic Extraction of Polysaccharides from Waste Corn Bract: Process Optimization, Characterization, Antioxidant and Anti-Diabetic PotentialsYihui Liu, Yayi Li, Na Niu et al.Corn bract is the main agricultural waste of corn production and processing. Little information is focused on its value-added utilization. In the present study, the Ultrasound-Assisted Enzymatic Extraction (UAEE) was used for the first time to extract Corn Bract Polysaccharides (CBPs). The optimum conditions of UAEE for CBPs extraction were: Cellulase amount of 0.7%, enzymolysis for 58 min, and ultrasound … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 28 Jun 2022 · 6,129 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation 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 · 6,652 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Ultrasonic-Assisted Total Flavonoids Extraction from Flower of Albizia Julibrissin Durazz. by Response Surface Methodology for Characterization of Chemical Profile and Evaluation of Antioxidant and Tyrosinase Inhibitory ActivitiesYijie Cheng, Yuwen Zhang, Hanzhang Sun et al.To investigate the flavonoids in flower of Albizia julibrissin (‘He Huan Hua’ in Chinese), the ultrasonic-assisted extraction of total flavonoids from ‘He Huan Hua’ was optimized by response surface methodology and the chemical profile was characterized by HPLC- QTOF-MS/MS. What’s more, the antioxidant and tyrosinase inhibitory activities of ‘He Huan Hua’ were also evaluated in this study. The extraction time, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 14 Mar 2022 · 6,737 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of Flavor Properties of Sufu by HS-SPME/GC-MS, Electronic Nose and Electronic Tongue Combined with Multivariate Statistical AnalysisXiaoli Xi, Yanli Ma, Jingxuan Ke et al.Flavor is the main quality characteristic of sufu. The flavor of different types of sufu varies greatly, which will affect the preference and selectivity of consumer for sufu. To explore the flavor characteristics and distinguishing methods in different types of sufu, the volatile flavor components and free amino acids of 5 kinds of commercial sufu were determined by HS-SPME/GC-MS and … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 12 Jan 2022 · 6,400 accessesView PDFCite
