Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Iron deficiency is a common nutritional problem and results in anemia in human population. Heme iron (HI) is known to be a better iron supplement than non-HI because of its fewer gastrointestinal side effects. HI polypeptide (HIP) is prepared by enzymatic digestion of hemoglobin from animal blood and subsequent ultrafiltration or dialysis. Here we find a polymerized form of HIP with high iron content and provide an efficient method to prepare the HIP polymer. The molecular weight of the HIP polymer was around 250 kDa, which was determined by gel filtration. The polymer was soluble in a wide range of pH, and iron content was about 1.8%, that is the highest among any other forms of HIP. Moreover, when administered to healthy human, the polymer increased serum iron level twofold, 5 h after the administration. These data indicate that the HIP polymer containing high level of iron can be used as an ideal iron supplement in anemic patients. © 2010, Wiley Periodicals, Inc.
