Caenorhabditis elegans is an exceptionally valuable model for aging research because of many advantages, including its genetic tractability, short lifespan, and clear age-dependent physiological changes. Aged C. elegans display a decline in their anatomical and functional features, including tissue integrity, motility, learning and memory, and immunity. Caenorhabditis elegans also exhibit many age-associated changes in the expression of microRNAs and stress-responsive genes and in RNA and protein quality control systems. Many of these age-associated changes provide information on the health of the animals and serve as valuable biomarkers for aging research. Here, we review the age-dependent changes in C. elegans and their utility as aging biomarkers indicative of the physiological status of aging.

With praziquantel being the sole available drug for schistosomiasis, identifying novel anthelmintic agents is imperative. A chemical investigation of the fruiting body of the bioluminescent mushroom Berk. resulted in the isolation of new conjugated long-chain fatty acids (8,10,12,13)-12,13-dihydroxy-7-oxo-octadeca-8,10-dienoic acid () and (7,8,9,11)-7,8-dihydroxy-13-oxo-octadeca-9,11-dienoic acid () and three previously described compounds, (7,8,9)-7,8-dihydroxyoctadec-9-enoic acid (), (2)-dec-2-ene-1,10-dioic acid (), and a ketolactone marasmeno-1,15-dione ().

Copper, as a vital trace element and ubiquitous environmental pollutant, exhibits a positive correlation with the neurodegenerative diseases. Recent studies have highlighted ferroptosis's significance in heavy metal-induced neurodegenerative diseases, yet its role in copper-related neurotoxicity remains unclear. This study aimed to investigate the role of ferroptosis in copper-induced neurotoxicity.

With the increasing incidence of non-hereditary Parkinson's disease (PD), research into the involvement of specific environmental factors, in addition to aging, has become more prominent. The effects of microplastic exposure on public health have gained increased attention as it is known to cause a range of neurotoxic changes, some of which are similar to the pathological features of PD. We carried out low-dose microplastic exposure experiments on mice and Caenorhabditis elegans models and implemented a survey regarding the utilization of plastic products in the population.

Emerging contaminants in estuarine sediments, such as bis(2-ethylhexyl) phthalate (DEHP) and titanium dioxide nanoparticles (nTiO), pose ecotoxicological risks that may be exacerbated by co-contamination. This study investigated the impacts of DEHP, nTiO, and their combinations at environmentally relevant concentrations (1, 10, and 100 μg/g) on the soil nematode Caenorhabditis elegans in estuarine-like sediment (14.25‰ salinity).
