Carbon monoxide (CO) is a toxic gas that can be lethal in large doses and may also cause physiological damage in lower doses. Epidemiological studies suggest that CO in lower doses over time may impact on embryo development, in particular cardiac development, however other studies have not observed this association. Here, we exposed chick embryos in ovo to CO at three different concentrations (1ppm, 8ppm, 25ppm) plus air control (4 protocols in total) for the first nine days of development, at which point we assessed egg and embryo weight, ankle length, developmental stage, heart weight and ventricular wall thickness. We found that heart weight was reduced for the low and moderate exposures compared to air, and that ventricular wall thickness was increased for the moderate and high exposures compared to air. Ventricular wall thickness was also significantly positively correlated with absolute CO exposures across all protocols. This intervention study thus suggests that CO even at very low levels may have a significant impact on cardiac development.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
