Sample Preparation of Caenorhabditis elegans for GC-MS-Based Metabolomics in Toxicity Assessment.
Methods Mol Biol
January 2025
Fytagoras BV, Leiden, The Netherlands.
The nematode Caenorhabditis elegans, widely recognized as a model organism due to its ease of breeding and well-characterized genomes, boasts complete digestive, reproductive, and endocrine systems, as well as conserved signaling pathways shared with mammals. It has become an invaluable resource for metabolomics research, particularly in examining responses to chemical or environmental factors and toxicity assessments. In this article, we provide detailed, step-by-step protocols for cultivating C.

In vitro models that can faithfully replicate critical aspects of kidney tubule function such as directional drug transport are in high demand in pharmacology and toxicology. Accordingly, development and validation of new models is underway. The objective of this study was to characterize physiologic and transport functions of various sources of human renal proximal tubule epithelial cells (RPTECs).

Managing conflicts of interest (COIs) in scientific decision-making is important for minimizing bias and fostering public trust in science. Proper management of COIs has added significance when scientists are making decisions that impact public policy, such as assessing substances for carcinogenicity. The International Agency for Research on Cancer (IARC) organizes expert working groups to identify putative carcinogens and determine whether or not the hazard is likely to present significant potential harm to humans.

College of Chemistry and Pharmacy, Qingdao Agricultural University, Qingdao 266109, Shandong, PR China. Electronic address:
The presence of a synergistic effect between carrier and insecticide in controlled release formulations is highly desirable to improve efficacy to target pests and reduce insecticide use. Herein, controlled release microparticles of avermectin (AVM) were fabricated using natural chitosan (CTS) as a carrier by a pH adjustment method. The resulted AVM@CTS microparticles displayed high encapsulation efficiency (73.

One of the main factors that have made it difficult to control malaria is the large number of parasites that are resistant to the usual antimalarial drugs. Therefore, the development of new drugs that are more effective and with low toxicity for humans is necessary. In this work, we evaluated the adduct 2-(3-hydroxy-1-methyl-2-oxoindolin-3-yl) acrylonitrile, also called CHISACN, as a potential antimalarial through in vitro studies, and evaluated its effects in silico and in vivo toxicology.
