Macrolide pollution has attracted a great deal of attention because its ecotoxic effects on microalgae, but the role phycospheric bacteria under antibiotic stress remains unclear. This study explored toxic erythromycin (ERY) growth and nitrogen metabolism Auxenochlorella pyrenoidosa; then, it analyzed predicted composition ecological function microalgae ERY stress. We found that 0.1, 1.0, 10 mg/L inhibited chlorophyll gradually showed enhanced abilities over course 21 days. As exposure time progressed, nitrate reductase activities increased, remained significantly lower than control group at d. NO3− concentrations in all treatment groups decreased were consistent with growth. NO2− three those during changed community diversity bacteria. The relative abundance bacteria, such as unclassified-f-Rhizobiaceae, Mesorhizobium, Sphingopyxis, Aquimonas, Blastomonas, varied to different degrees. Metabolic functions, ABC transporters, microbial diverse environments, biosynthesis amino acids, upregulated treatments higher (1.0 mg/L). Higher denitrification, nitrous oxide nitrite respiration. findings this suggest alleviate restore by regulating system.

Introduction Sodium dodecyl sulfate (SDS), a widely used surfactant in detergents, has raised concerns due to its potential health risks, particularly children. This study evaluates the impact of SDS exposure on GH secretion GH3 cells, focusing oxidative stress as key mechanism. Methods cells were treated with varying concentrations (0.001–10 mM) for 24 or 48 h. Cell viability was assessed using MTT assay, while quantified via ELISA. Oxidative levels evaluated through ROS fluorescence assays, and gene expression Nrf2, IL-6, TNF-α, caspase-3 analyzed qPCR. Additionally, antioxidant N-acetylcysteine (NAC) determine protective effects against SDS-induced stress. Results led dose-dependent decrease cell viability, identified primary driver. Nrf2 exhibited biphasic response, showing transient upregulation at low doses but suppression higher concentrations, exacerbating damage. NAC treatment reduced partially restored secretion, confirming role toxicity. Discussion These findings suggest that may disrupt endocrine function, warranting further risk assessment safety consumer products. Given SDS’s prevalence household products, future research should focus long-term children therapeutic interventions mitigate

Published: March 1, 2024

To date, the radiation-adaptive response has been reported as a low-dose-related phenomenon and associated with radiation hormesis. Well-known cancers are caused by non-radiation active reactants, in addition to radiation. A model of suppression for radiation-specific was previously reported, but did not target radiation-nonspecific cancers. In this paper, we describe kinetic models radiation-induced suppressors general non-specific cancers, estimating dose M that induces maximum hormesis effect while satisfying condition risk is approximately proportional above NOAEL (No Observed Adverse Effect Level). The maximal when rate constant generation risk-reducing factor same its decomposition. When two constants different, at which maximized depends on both constants, increases approach each other, reaching dose. theory proposed paper can only explain existing experiments extremely short error bar lengths. This may lead discovery unknown low doses development methods future.

Setaria viridis (green foxtail) is an invasive weed species in various agricultural systems, prompting the search for effective compounds to control its germination. The has primary and secondary dormancy depending on time elapsed since post-harvesting, making management strategies more difficult. Several plants, such as Lantana camara L., can be a source of allelochemicals with herbicidal effects, being potential candidate S. viridis. We investigated effects L. extracts germination initial growth seeds different degrees revealed dose-dependent bioherbicide effect. Aqueous were analyzed by HPLC-DAD applied (0.1 5.0 mg/mL) 12- 110-day post-harvest seeds. Seeds evaluated daily percentage (GP), speed index (SGI), radicle length (RL) calculated. Phenolic acids flavonoids major components extract. Lower concentrations 0.5 stimulated accelerated viridis, breaking dormancy. Both 1.0 mg/mL hindered germination, especially 12 dph concentration resulted longer roots, whereas inhibited root development. potentially stimulate at low while inhibiting these parameters higher doses. These results may open new possibilities using weed-control strategies.
