The lateral entorhinal cortex (LEC) contains glutamatergic projections that innervate the nucleus accumbens (NAc) and may be involved in the encoding of contextual associations with both positive and negative valences, such as those encountered in drug cues or fear conditioning. To determine whether LEC-NAc neurons are activated by the encoding and recall of contexts associated with cocaine or footshock, we measured c-fos expression in these neurons and found that LEC-NAc neurons are activated in both contexts. Specifically, activation patterns of the LEC-NAc were observed in a novel context and reexposure to the same context, highlighting the specific role for LEC-NAc neurons in encoding rather than the valence of a specific event-related memory.

- Surfactants are unique molecules that can reduce surface tension and help break down oils, making them essential in products like detergents and cleaners.
- Two major types of nonionic surfactants, alkylphenol ethoxylates (APEOs) and alcohol ethoxylates (AEOs), are widely used in many household and industrial applications, but they are also contributing to environmental contamination.
- Recent studies show that these surfactants can disrupt metabolic health, particularly through affecting thyroid hormone signaling, highlighting the need to further explore their harmful effects in various biological models.
In vitro endocrine and cardiometabolic toxicity associated with artificial turf materials.
Environ Toxicol Pharmacol
October 2024
Artificial turf, a consumer product growing in usage in the United States, contains diverse chemicals, some of which are endocrine disruptive. Endocrine effects from turf material extracts have been primarily limited to one component, crumb rubber, of these multi-material products. We present in vitro bioactivities from non-weathered and weathered turf sample extracts, including multiple turf components.

While there is growing evidence for effects on births in hydraulic fracturing/UOG regions and good mechanistic evidence for potential reproductive toxicity, there is much research still needed to make firm conclusions about these practices and reproductive health.
Abstract: Unconventional oil and natural gas (UOG) operations have emerged over the last four decades to transform oil and gas production in the United States and globally by unlocking previously inaccessible hydrocarbon deposits.
