Effects of Exposure to 5.8 GHz Electromagnetic Field on Micronucleus Formation, DNA Strand Breaks, and Heat Shock Protein Expressions in Cells Derived From Human Eye
Authors not listed · 2019
Acute cold exposure increased energy expenditure by 52% and altered inflammatory and lipid biomarkers in twenty subjects.
Plain English Summary
Twenty subjects underwent 30 minutes of acute cold exposure with blood drawn at baseline, during exposure, and two hours after. Acute cold exposure increased heart rate by 11%, shivering sensations fourfold, pain twofold, oxygen consumption by 50%, and energy expenditure by 52%. IL-1? rose 24% at 30 minutes and 65% at two hours post-exposure, alpha-2-macroglobin rose 16% at 30 minutes then returned to baseline, and HDL rose 15% at two hours. Sex differences were observed for IL-2, IL-6, IL-8, ferritin, alpha-2-macroglobin, and HDL.
Why This Matters
The study aimed to fill a gap in data on inflammatory and lipid biomarkers related to cardiovascular disease after acute cold exposure. Researchers measured ten cytokines, nine acute phase proteins, and five lipid biomarkers in plasma. Heart rate, oxygen consumption, energy expenditure, shivering, and pain were recorded before and during the cold exposure. The authors concluded that acute cold exposure increases energy expenditure and modifies inflammation, the acute phase response, and lipid metabolism.
