Research ArticleOpen accessIn the abstractComparative Characterization of Small Mammal Communities in Forest-Steppe and Steppe Landscapes of the South of Western and Central SiberiaZarina Mukhtarovna Sergazinova, Alexander Vladimirovich Makarov, Aliya Toleuzhanovna Toleuzhanova et al.This study analyzes the fauna, population, and distribution patterns of small mammals of forest-steppe and steppe landscapes of the south of Western and Central Siberia for the period between 1998 and 2021 on the basis of literature data and authors' own materials. Most of these studies were local in nature, while our work is characterized by a generalizing and comparative … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 4 Dec 2024 · 4,549 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractStable Isotope Diet Reconstruction of Feral Horses on the Sheldon National Wildlife Refuge, Nevada, USAMegan K. Nordquist, Todd F. Robinson, Gail H. Collins et al.Feral horse management has become a subject of significant controversy in the United States, resulting in part from opposing views of best management practices and limited empirical data. Feral horse densities increase in response to high reproductive rates and limited horse removal. with this increase, land managers are challenged with accurately quantifying horse diet selection and subsequent impacts on western … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 4 Mar 2024 · 5,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Impact of Acidity and Alkalinity on the Microbial Community Structure in Urban RiversDongmei Shen, Cairui Yu, Xinwei Song et al.To address the impact of low-temperature pH on the microbial community structure of river sediment in urban rivers during winter, the sediment of the Pi River was sampled to investigate. Four experimental samples were designed by varying the pH to 5.0, 7.0, and 8.5 based on the original sample (pH = 5.5) and the characteristics of the microbial community were … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 8 Aug 2023 · 4,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractMarine-Derived Extracts as Economically Sustainable and Ethical Alternatives to Fetal Bovine Serum in HEK293 Cell CultureKian Kenneth Francisco Sanchez, Jennifer Seki-Wong et al.Fetal Bovine Serum (FBS) is a staple supplement in cell culture, providing key growth factors that promote cell health and proliferation. Since 1885, cell culture has been a cornerstone of both basic and applied research, leading to significant discoveries of cell communication and function. However, the use of FBS presents economic and ethical challenges. Millions of bovine fetuses are euthanized … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 7 Aug 2026 · 1,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Metformin Treatment on Inflammatory Factors and Gut Microbial Diversity in Patients with Type II Diabetes MellitusLei Tong, Jingjing Zhang, Li Xiao Yue et al.With the persistent rise in the prevalence of Type 2 Diabetes Mellitus (T2DM), traditional treatment evaluations have primarily focused on glycemic control, often overlooking the multidimensional effects of medications. As a first-line therapeutic agent, the anti-inflammatory effects and gut microbiota regulation mechanisms of metformin remain incompletely elucidated. This prospective cohort study established a metformin treatment group and a T2DM control … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 20 Jul 2026 · 774 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitric Oxide Treatment Improves the Antioxidant Capacity While Inhibiting Anthocyanin Biosynthesis of Peach Fruit (‘Xiahui-8’) During RipeningZiqi Wang, Yanyan Li, Yingling Deng et al.Nitric Oxide (NO) is an important bioactive signal molecule that plays an important role in diverse physiological processes. This study aimed to explore the effects of Nitric Oxide (NO) treatments on postharvest peach fruit. Specifically, we examined changes in quality attributes, antioxidant ability, and anthocyanin profiles during storage, given the important role of NO as a bioactive signal molecule in … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,392 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Proteins in Two Typical Chinese Thin-Shell WalnutsXu Meng, Tian YilingThis study compared functional properties and molecular characteristics of proteins from two thin-shelled walnut (Juglans regia L.) cultivars predominantly grown in China: Wen 185 and Lvling. Wen 185 walnut protein demonstrated significantly superior performance compared to Lvling across multiple functional parameters, including solubility, emulsifying capacity, foaming capacity, water absorption, and oil absorption. Molecular weight distribution analysis revealed that both proteins … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Changes in Forage Vegetation for Saiga (Saiga Tatarica) On Natural Pastures in The Steppe Zone of the West Kazakhstan RegionAmanay Myrzabayev, Zhanbolat Ibraibekov, Zhangeldi Ussenov et al.This study investigates the impact of recent climate changes and reduced anthropogenic pressure on the vegetation cover in the steppe regions of Russia and Kazakhstan, particularly focusing on the effects on saiga (Saiga tatarica) populations. By the late 1990s, a significant shift towards the dominance of grasses and the reduction of herbaceous plants in semi-arid and arid regions was observed, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Feb 2026 · 1,765 accessesView PDFCite
