Inhibition mechanism of Microcystis aeruginosa in coculture of Lemna and Azolla: Insights from non-targeted Metabonomics.

Microcystis aeruginosa, a harmful alga in cyanobacterial blooms, damages aquatic ecosystems. Species diversity may control the blooms by increasing ecosystem stability and resource utilization. The growth and photosynthetic systems of M.

Subcutaneous route is a reliable alternative for ACTH-stimulated steroid profiling.

Purpose: Intramuscular acton prolongatum is most often used as an alternative for intramuscular or intravenous tetracosactide for ACTH stimulation in some countries. Intramuscular administration of acton prolongatum is cumbersome whereas intended intramuscular acton prolongatum or tetracosactide may often turn subcutaneous. Hence, we compared the subcutaneous ACTH-stimulated steroid profiling with those of the intramuscular routes.

Shared Pheromone Compounds in Neotropical Rice Stink Bugs: The Role of Zingiberenol and Sesquipiperitol.

The small black stem bug, Paratibraca (= Glyphepomis) spinosa (Campos and Grazia 1998), is a rice pest in Brazil and is part of a complex of stink bugs that includes Oebalus poecilus (Dallas) and Tibraca limbativentris Stål. Together, these pentatomid species pose a serious threat to rice crops throughout South America. In this study, we identified the sex pheromone of P.

Approaches for the preparation and evaluation of hydrophilic polyethylene and polyethylene terephthalate microplastic particles suited for toxicological effect studies.

When performing effect studies to investigate the impact of microplastic (MP) on cell lines, algae, or daphnia, it is advantageous if such experiments can be performed without the use of surfactants. The need for surfactants arises from the fact that finely milled pristine MP particles generally are hydrophobic. Methods for the preparation of larger amounts of hydrophilic and hence artificially aged MP particles and approaches for their characterization are of high importance.

2024 White Paper on Recent Issues in Bioanalysis: Three Way-Cross Validation; Urine Clinical Analysis; Automated Methods; Regulatory Queries on Plasma Protein Binding; Automated Biospecimen Management; ELN Migration; Ultra-Sensitivity Mass Spectrometry ( - Recommendations on Advanced Strategies for Mass Spectrometry Assays, Chromatography, Sample Preparation and BMV/Regulated Bioanalysis - Regulatory Agencies' Inputs on Regulated Bioanalysis/BMV).

The 18 Workshop on Recent Issues in Bioanalysis (18 WRIB) took place in San Antonio, TX, USA on May 6-10, 2024. Over 1100 professionals representing pharma/biotech companies, CROs, and multiple regulatory agencies convened to actively discuss the most current topics of interest in bioanalysis. The 18 WRIB included 3 Main Workshops and 7 Specialized Workshops that together spanned 1 week to allow an exhaustive and thorough coverage of all major issues in bioanalysis of biomarkers, immunogenicity, gene therapy, cell therapy and vaccines.
