Drug combination assays using Caenorhabditis elegans as a model system.

The C. elegans drug combination assay evaluates the effects of drug combinations in the nematode Caenorhabditis elegans, serving as a valuable tool to assess the efficacy of pharmaceutical agents and natural compounds. Using C.

Rhythms in lipid droplet content driven by a metabolic oscillator are conserved throughout evolution.

The biological clock in eukaryotes controls daily rhythms in physiology and behavior. It displays a complex organization that involves the molecular transcriptional clock and the redox oscillator which may coordinately work to control cellular rhythms. The redox oscillator has emerged very early in evolution in adaptation to the environmental changes in O levels and has been shown to regulate daily rhythms in glycerolipid (GL) metabolism in different eukaryotic cells.

Novel interplay between agonist and calcium binding sites modulates drug potentiation of α7 acetylcholine receptor.

Drug modulation of the α7 acetylcholine receptor has emerged as a therapeutic strategy for neurological, neurodegenerative, and inflammatory disorders. α7 is a homo-pentamer containing topographically distinct sites for agonists, calcium, and drug modulators with each type of site present in five copies. However, functional relationships between agonist, calcium, and drug modulator sites remain poorly understood.

Developmental exposure to arsenic reduces anxiety levels and leads to a depressive-like behavior in female offspring rats: Molecular changes in the prefrontal cortex.

Exposure to inorganic arsenic (iAs) detrimentally affects the structure and function of the central nervous system. In-utero and postnatal exposure to iAs has been connected to adverse effects on cognitive development. Therefore, this investigation explores neurobehavioral and neurochemical effects of 0.

Evaluating anthelmintic activity through egg hatching assay.

The egg hatching methodology is a valuable tool for assessing the anthelmintic activity of drugs and compounds and evaluating anthelmintic drug efficacy. Isolated eggs from gravid adults are exposed to different concentrations of selected drugs and the percentage of egg hatching is determined with respect to the control condition. The assay allows the construction of concentration-response curves and determination of EC or EC values for egg hatching inhibition.
