Article Synopsis
- The study investigated the presence of natural radionuclides from the uranium decay chain in a coastal ecosystem in southern Mexico, which is minimally impacted by industrial activity.
- The researchers used high-resolution gamma-ray spectrometry and alpha-particle spectrometry to measure the activity concentrations of uranium, radium, lead, and polonium in sediment and water samples.
- Findings revealed specific activity concentration ranges in sediment and water, establishing a radiometric baseline for comparison with other coral reef ecosystems globally.
Epidemiological studies have associated long-term exposure to environmental air pollution particulate matter (PM) with the development of diverse health problems. They include infectious respiratory diseases related to the deregulation of some innate immune response mechanisms, such as the host defense peptides' expression. Herein, we evaluated in BALB/c mice the effect of long-standing exposure (60 days) to urban-PM from the south of Mexico City, with aerodynamic diameters below 2.

They include autoantibodies against fibrillarin (Fb), which are serological markers for SSc. Fb is associated with the evolutionally-conserved box C/D of small nucleolar RNAs (snoRNAs).
