Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Comparative transcriptomics and phylostratigraphy of Argentine ant odorant receptors.

PLoS ONE
Nestmate recognition in ants is regulated through the detection of cuticular hydrocarbons by odorant receptors (ORs) in the antennae. These ORs are crucial for maintaining colony cohesion that allows invasive ant species to dominate colonized ...

Identification of morphological and chemical markers of dry- and wet-season conditions in female Anopheles gambiae mosquitoes

Parasites & Vectors, 2014
Background Increased understanding of the dry-season survival mechanisms of Anopheles gambiae in semi-arid regions could benefit vector control efforts by identifying weak links in the transmission cycle of malaria.

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...

Specialized odorant receptors in social insects that detect cuticular hydrocarbon cues and candidate pheromones

Nature Communications, 2017
Cuticular hydrocarbons (CHC) mediate the interactions between individuals in eusocial insects, but the sensory receptors for CHCs are unclear. Here the authors show that in ants such as H.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Review of the cuticular lipids of spiders (Araneae)

European Journal of Entomology
Cuticular lipids are essential for the functioning of all arthropods. They maintain water balance, are involved in intraspecific and interspecific chemical communication and prevent fungal and bacterial infections.

Real‐World Effectiveness, Treatment Course, and Safety of Tapinarof Cream 1% for Atopic Dermatitis and Plaque Psoriasis in Japan

The Journal of Dermatology, EarlyView.
ABSTRACT Background Tapinarof cream 1%, a non‐steroidal topical aryl hydrocarbon receptor‐modulating agent, is approved in Japan for atopic dermatitis (AD) and plaque psoriasis. Real‐world data on longitudinal outcomes, treatment continuation, interruption and restart, and adverse‐event timing are limited. Methods This single‐center retrospective study

HOST MATTER: Parasite infection drives chemical reconfiguration of decomposing host and shapes insect behavioural responses

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host–parasite interactions shape ecosystems by driving species dynamics, yet their influence is typically considered in terms of host mortality rather than the chemical environments generated during infection and decomposition.
