The Claim

Selenium nanoparticles of 40.4 nm size, administered at 50 μg Se/kg/day for 24 weeks to apolipoprotein E-deficient mice on a high-fat diet, are associated with greater increases in atherosclerotic lesions and oxidative stress compared to selenium nanoparticles of 23.1 nm or 86.8 nm size under the same conditions.

Source: Long-term administration of low-dose selenium nanoparticles with different sizes aggravated atherosclerotic lesions and exhibited toxicity in apolipoprotein E-deficient mice.

In plain English

In mice genetically predisposed to atherosclerosis and fed a high-fat diet, selenium nanoparticles of 40.4 nanometers caused larger increases in arterial plaque and oxidative stress markers than nanoparticles of 23.1 or 86.8 nanometers when given at the same dose for the same duration.

See the scientific wording

Selenium nanoparticles of 40.4 nm size, administered at 50 μg Se/kg/day for 24 weeks to apolipoprotein E-deficient mice on a high-fat diet, are associated with greater increases in atherosclerotic lesions and oxidative stress compared to 23.1 nm or 86.8 nm nanoparticles.

Why this might work

Selenium nanoparticles of 40.4 nm size enter the body more efficiently than other sizes, settle in the liver and blood vessels, block natural antioxidant enzymes, cause a buildup of harmful molecules that damage fats and cells, and disrupt the liver's ability to manage fats. This leads to more fat in the blood and more damage to artery walls, making plaques grow larger and become more unstable.

  1. Study: Long-term administration of low-dose selenium nanoparticles with different sizes aggravated atherosclerotic lesions and exhibited toxicity in apolipoprotein E-deficient mice.

    In mice prone to heart disease, scientists gave three different sizes of selenium nanoparticles for six months. The 40.4 nm ones made the arteries worse and caused more cell damage than the smaller or larger ones.
