Homocysteine is a metabolite of methionine that may be remethylated by enzymes requiring folate and cobalamin (vitamin B12) to again form methionine or catabolized by the pyridoxine (vitamin B6) dependent enzyme, cystathionine beta synthase (CBS) to form cysteine (fig. 1) [1]. Homocysteine exists as a combination of various free and protein bound forms, but the total amount is what is usually measured and may be reported as homocyst(e)ine [2]. The biological plausibility that elevated homocysteine might lead to vascular disease noted in 1969 by McCully [3]. He reported that a child with abnormal cobalamin metabolism and hyperhomocysteinemia had arterial lesions similar to those seen in children with severe hyperhomocysteinemia from CBS deficiency. These findings led to the idea that moderate elevations in homocysteine, even those still within the so-called normal range, might also lead to vascular pathology through a variety of mechanisms including atherosclerosis and thrombosis [4].
This research output has an Altmetric Attention Score of 6. 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 11 October 2005.
All research outputs
#6,124,545
of 27,969,864 outputs
Outputs from Neuroepidemiology
#278
of 927 outputs
Outputs of similar age
#6,075
of 37,133 outputs
Outputs of similar age from Neuroepidemiology
#1
of 7 outputs
Altmetric has tracked 27,969,864 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 927 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.3. This one has gotten more attention than average, scoring higher than 64% 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 37,133 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 69% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
