Research ArticleOpen accessPhrase in the titleEffect of Super Absorbent Application on Antioxidant Enzyme Activities in Canola (Brassica napus L.) Cultivars under Water Stress ConditionsH. R. Tohidi-Moghadam, A. H. Shirani-Rad, G. Nour-Mohammadi et al.Problem statement: Drought stress significantly limits Canola (Brassica napus L.) growth and crop productivity. Hence, efficient management of soil moisture and study metabolic changes which occur in response to drought is important for agricultural production of this Crop. Approach: For a better understanding of drought tolerance mechanisms and improving soil water content management strategies, an experiment was laid out in … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIn vitro Ruminal Cumulative Gas and Methane Production, Enzyme Activity, Fermentation Profile and Nutrient Digestibility on Feed Supplemented with Organic SeleniumMoh. Sofi’ul Anam, Andriyani Astuti, Budi Prasetyo Widyobroto et al.Methane (CH4) emissions are indeed a global environmental concern and ruminants are a significant source of these emissions; however, there is limited understanding regarding the contribution of organic Selenium (Se) in mitigating CH4 emissions. Hence, this study investigated the impact of supplementing organic Se from Selenomethionine (Se-Met) on the in vitro ruminal cumulative gas and CH4 production, fermentation profile, enzyme … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 26 Oct 2023 · 5,215 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBinding Studies of Natural Product Berberine with DNA G-QuadruplexNagendra K. Sharma, Pooja Lunawat, Manjusha DixitProblem statement: The ends of chromosome had highly repetitive short G and C-rich sequences of DNA. These sequences were known to form stable tetraplex type of secondary structures which help to maintain gene integratity after cell divison. Approach: Any reagent which controls the random cell division would be useful to design anticancer drugs. Therefore a many natural and synthesized molecules … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 8,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory and Antioxidant Effects of Stachys Japonica Miq. Ethanol Extract on Cyclophosphamide-Induced Immunosuppressed Mice and its Phytochemical CompositionXueping Jiang, Jianglong He, Yanjun Chen, Fang WangStachys japonica Miq. is an edible wild botanical drug and a traditional medicine in China. This study focused on examining the phytochemical profile and antioxidant properties of the ethanol extract of S. japonica Miq (SJEE) in vitro, as well as its immunomodulatory and antioxidant activities in cyclophosphamide (Cy)-induced immunosuppressed mice. The SJEE was analysed by UPLC-HRMS/MS. 36 Polyphenols, including flavonoids, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 13 Apr 2026 · 1,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractPurification, Structural Characterization and Anti-Aging and Stress Activities of Cordyceps Mycelium Polysaccharides from Paecilomyces HepialiXiaokang Hu, Huixiu Ma, Guicai Chen et al.This study identified and characterized the bioactive polysaccharide components from Cordyceps mycelium powder (CMP) derived from Paecilomyces hepiali, evaluating their anti-aging and stress-protective activities. Initial screening using Drosophila melanogaster revealed that crude Cordyceps polysaccharides (CCP) exhibited comparable effects to CMP and Cordyceps aqueous extracts (CAE) on natural lifespan and UV stress resistance, suggesting CCP as the primary bioactive component. CCP … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnveiling the Potential of Dombeya buettneri K.Schum As a Drug Agent: Molecular Docking of Compounds With Enzymes Linked to Diabetes and Neurodegenerative DiseaseEsther Emem Nwanna, Samuel Chima Ugbaja et al.This study investigated the mechanisms of Dombeya buettneri (snowball leafy) extracts on diabetes, hypertension, and neurodegenerative diseases. It compared extracts obtained using steep water (a by-product of corn wet milling) and aqueous water. The extracts were analyzed for total phenol, total flavonoid content, antioxidant activities such as FRAP, ABTS, NO, DPPH, iron-induced lipid peroxidation assay, degradation of deoxyribose (Fenton’s reaction), … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Feb 2026 · 2,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on the Enhancement of Hypoglycemic and Antioxidant Activities of Compound Herbal Tea through Solid-State FermentationQing Liu, Xiaowen Que, Yueping Yang et al.This study utilized Aspergillus niger KY2295 for the Solid-State Fermentation (SSF) of a compound tea made from Cinnamomum cassia bark, Glycyrrhiza glabra, Morus abla L. leaf, and Crataegus oxyacantha L. to enhance its hypoglycemic effects. The fermentation process was optimized using single-factor experiments and a Central Composite Design (CCD), with α-amylase and α-glucosidase inhibitory activities as evaluation indices. Following fermentation, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 May 2025 · 5,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Soil Storage at Freezing Temperatures on Soil Enzymatic ActivitiesAinsley Lougheed, Kabwe NkongoloSoil enzyme activities are good indicators of soil health. It has been hypothesized that soil storage before analysis might affect microbial function. The objective of the present study was to determine if soil storage at -20 and -80°C affects soil enzymatic activities. Soil samples were collected and stored for four weeks at -20 and -80°C. Activities of nine enzymes were … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 12 Aug 2024 · 4,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Enzymatic Role of Lipid Metabolism in Yarrowia lipolytica Grown on GlycerolRuixue Wang, Feifei Xin, Yufei Chang et al.More attention has been paid to the production of commercial fatty acids by microbial fermentation. The basic biochemistry of lipid accumulation in oleaginous microorganisms under nitrogen limitation has been extensively studied. As an oleaginous microorganism, Yarrowia lipolytica can produce fatty acid-derived biofuels and biochemicals. However, the response of the enzymes in Y. lipolytica to glycerol remains unclear.
