Metric Options: Counts1 Year3 YearSelecting 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
Oxidative stress has been implicated in the pathophysiology of chronic diseases and cigarette smoking is known to be one of the major sources of oxidants. In this study, we investigated whether Korean black raspberry (BR) supplementation could reduce smoke-induced oxidative stress in healthy male smokers. Thirty nine healthy male smokers received either 30 g of freeze-dried BR or placebo for four weeks. Anthropometric and dietary data, smoking history, blood lipid profiles, lipid peroxidation, DNA damage, and antioxidant enzyme activities were assessed at baseline and after supplementation. There was no difference of age, smoking history, anthropometry, and nutrient intake between groups. BR supplementation had no effect on plasma lipid profiles, LDL oxidation, and DNA damage. However, it significantly increased the activity of the antioxidant enzymes, glutathione peroxidase and catalase, and reduced plasma lipid peroxidation. In conclusion, BR supplementation may decrease cigarette smoke-induced oxidative stress through increase of endogenous antioxidant enzyme activities.
