Research ArticleOpen accessIn the abstractChlorophyll and Protein Changes Observed Post Co-Cultivation of Explants with Agrobacterium Tumefaciens in Soybean (Glycine max L. Merr.)Phetole MangenaAlthough, Agrobacterium-mediated genetic transformation represents a major milestone in agricultural biotechnology for crop improvement against biotic and abiotic stresses. Further insights on the interactions between this bacterium and explants required for in vitro plant regeneration remain scant. This study investigated the changes in chlorophyll content and protein profiles of cotyledonary node explants co-cultivated with A. tumefaciens in soybean. Soybean seeds … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 7 Dec 2022 · 5,046 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPreparation, 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 · 5,207 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrasound-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 · 6,126 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign, Fabrication and Operational Evaluation of a Co-Pyrolysis System for Waste-Plastics Derived Fuels: A Study of Edo NorthKevin Otoikhian, Ubani Oluwaseun Amune, Kennedy Edogamhe et al.This research work designed, developed and assessed the performance of a co-pyrolysis system generating waste-plastic extract fuels from mixed Municipal Waste Plastics (MWP) while evaluating High-Density Polyethylene (HDPE), Polypropylene (PP) and Polystyrene (PS) as the main municipal waste plastic sources. The materials selected for the reactor were carefully studied to meet the pyrolysis system's strength, operability and safety requirements.

EditorialOpen accessIn the abstractIs Rerum® the New Coley's Vaccine?Marco RuggieroColey's Vaccine and Cancer Immunotherapy Dr. William B. Coley is credited for having been the first to translate the observation of an association between bacterial infections, high fever and cancer remission into a successful cancer treatment. However, it is worth noting that such an association dates back to at least one century before Coley's times; as Wiemann and Starnes from … …American Journal of Immunology, Vol. 13, Issue 2 · 31 May 2017 · 12,281 accessesView PDF Cite

EditorialOpen accessIn the abstractChasing the Fat Demon: Fat Chance, Buddy?David L. Katz, Joachim Storsberg, Christian SchmidtScience is an interesting profession. At times, one could get caught up in his or her own world of thoughts, perception, far away from reality, sometimes referred to as the proverbial ivory tower (Lederberg, 1972). Science for the sake of science is, per se, not without merit, with our fragmented understanding of a given issue providing ample justification for experimentation … …American Journal of Immunology, Vol. 13, Issue 2 · 29 May 2017 · 8,134 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of Ferrous Ion Chelating Properties of Collagen Peptides from Dried and Fresh Cod SkinMengqian Chen, Cen Chen, Junchao Wu et al.Fish skin is a potential source of collagen and collagen is a protein source of bioactive peptides including iron chelating peptides. The aim of this study is to compare physicochemical properties of collagen extracted from fresh and dried cod skin and the ferrous ion chelating properties of collagen hydrolysates. Then the fresh and dried cod skin extracted collagen was hydrolyzed … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 2 Jul 2021 · 7,155 accessesView PDF Cite
