Research ArticleOpen accessIn the keywordsSpectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted SoilsA. Mihaly-Cozmuta, L. Mihal Cozmuta, V. Viman et al.The study presents the level of soil pollution in the area adjacent to three sedimentation ponds as a result of an environmental accident. Soil samples from various sites have been collected and analyzed to determine the concentration of heavy metals (Cu, Pb, Zn) and total cyanides. The analysis methods used were ICP-AES for heavy metals and the colorimetric for total … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractQualitative Analysis of the Chemical Composition of Cinnamomum tamala leaves and Biological ActivityQianwen Gong, Pin Chen, Linyang Wang, Shuge TianCinnamomum tamala (Buch.-Ham.) Nees and Ebermaier. (Lauraceae) is a less explored medicinal plant in Uyghur medicine, with limited knowledge about its non-volatile compounds. We utilized chemical pre-screening in conjunction with UPLC-Q-Orbitrap-MS to analyze the phytochemical makeup of C. tamala leaves. Total polyphenols were measured using the Folin-Ciocalteu method, while total flavonoids were quantified through NaNO2-Al (NO3)3 colorimetric analysis across four … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 659 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Biochemical and Hormonal Parameters in Male Patients with MigraineDua’a AlHassoon, Omar Atrooz, Husni FarahMigraine is a complex neurological disorder, including hormonal and biochemical imbalances. The physiological changes include neural variations due to genetic, environmental, and lifestyle factors. Therefore, the research aims to investigate total testosterone levels, Acetylcholine (Ach), prolactin, and clinical markers (calcium, magnesium, glucose, and lipid profile) across migraine patients. The research employed a case-control observational design conducted at Al-Ahliyya Amman University, … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 22 Jul 2026 · 815 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Multi-Enzyme Machine Cleaning, Multi-Enzyme Soaking, and Traditional Tap Water Cleaning on the Cleanliness of Blood-Contaminated Hemostatic ForcepsLi Kang, Qingmin Gao, Yi FengEffective cleaning of surgical instruments is critical for infection prevention in healthcare settings. This study compared the cleaning efficacy, efficiency, and resource consumption of three methods, multi-enzyme machine cleaning (Group S1), multi-enzyme soaking (Group S2), and traditional tap water cleaning (Group S3), on blood-contaminated hemostatic forceps. A total of 600 blood-contaminated hemostatic forceps collected from the disinfection supply room of … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 24 Apr 2026 · 1,881 accessesView PDFCite
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 abstractPotential of Fig Leaf (Ficus carica L.) as Immunomodulatory Agent in vitro and in SilicoAnita Dewi, Fitri Rahmayanti, Haidar Bagir et al.Natural remedies are increasingly being used as alternatives to conventional medicine, and their popularity is growing. The fig plant (Ficus carica L.), which is known to contain secondary metabolites such as alkaloids, flavonoids, phenolics, terpenoids, steroids, and saponins, has the potential to act as an immunomodulator. The purpose of this study was to determine the content of flavonoid compounds based … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 19 Jan 2023 · 6,232 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
