Previous toxicological research has suggested the potential neurotoxicity of ultrafine particulate matter (UFP, particles ≤0.1 μm in diameter). However, evidence from human beings, particularly regarding the neurodevelopmental impacts of UFP, is still limited.

DNA methylation is a critical step in brain development, 5-Methyl-2'-deoxycytidine (5mdC) is one of the global DNA methylation markers. Arsenic and lead exposures have been associated with neurotoxicity, which may be linked to epigenetic changes. Our research sought to investigate the correlation between 5mdC and developmental delay (DD) among preschoolers.

The posterior parietal cortex (PPC) is an associative neocortical region that integrates multiple streams of information and is implicated in spatial cognition and decision making. In some cases, however, the PPC is not required for these functions. One possibility is that the PPC is recruited when spatial complexity is high.

College of Life Science, Henan Normal University, Xinxiang 453007, China. Electronic address:
The widespread application of quantum dots (QDs) in recent years has raised concerns about potential environmental and human health risks. Although the toxicity of cadmium telluride quantum dots (CdTe QDs) has been partially studied, their effects on stem cells, tissue regeneration, neurodevelopment, and neurobehavioral toxicity remain unclear. This study aimed to investigate the combined toxic effects and mechanisms of CdTe QDs on planarians at the individual, tissue, cellular, and molecular levels.

Trans R Soc Trop Med Hyg
January 2025
School of Tropical Medicine and Global Health, Nagasaki University, Nagasaki 852-8102, Japan.
Background: Little is known about snakebites by Naja samarensis, a species unique to the Philippines. The aim here is to describe the clinical and epidemiological characteristics of patients bitten by this medically important cobra in the Eastern Visayas.
Methods: A hospital-based prospective study analysed the features of snakebite patients attending Eastern Visayas Medical Center between June 2022 and May 2023.
