| Abstract |
Apolipoprotein E knockout (apoE-KO) mice present synaptic loss, cognitive dysfunction, and high plasma lipid levels that may affect brain function simulating Alzheimer disease. Plasma and brain sterols were measured in apoE-KO and in wild type control mice on a cholesterol-free, phytosterol-containing diet by gas chromatography coupled to a mass spectrometer. Plasma cholesterol and phytosterols (campesterol and sitosterol) were higher in apoE-KO compared to control mice. Cholesterol precursors (desmosterol and lathosterol) were not detected in plasma of control mice but were present in apoE-KO mice. In the brain amounts of cholesterol, desmosterol, campesterol and 24-hydroxycholesterol were significantly lower in apoE-KO than in controls. There is a tendency in apoE-KO for lower values of 7α-hydroxycholesterol and 7β-hydroxycholesterol. Cholesterol content, synthesis rates (desmosterol) and export of 24-hydroxycholesterol are reduced in the brain of the severe hypercholesterolemic apoE-KO mice. |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 April 2018.
All research outputs
#4,461,115
of 23,867,274 outputs
Outputs from Journal of Bioenergetics and Biomembranes
#39
of 466 outputs
Outputs of similar age
#84,375
of 330,214 outputs
Outputs of similar age from Journal of Bioenergetics and Biomembranes
#2
of 9 outputs
Altmetric has tracked 23,867,274 research outputs across all sources so far. Compared to these this one has done well and is in the 80th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 466 research outputs from this source. They receive a mean Attention Score of 3.3. This one has done particularly well, scoring higher than 90% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 330,214 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 73% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
