Association of dietary total antioxidant capacity and its distribution across three meals with all-cause, cancer, and non-cancer mortality among cancer survivors: the US National Health and Nutrition Examination Survey, 1999-2018.

The effect of the antioxidant capacity of diet and its distribution across three meals on mortality risk among cancer patients remains unexplored. We aimed to prospectively investigate the association of dietary total antioxidant capacity (DAC) and its distribution across three meals with all-cause, cancer, and noncancer mortality among cancer survivors. We included 5,009 patients with cancer from the National Health and Nutrition Examination Survey conducted between 1999 and 2018.

Determination of uric acid in serum by SERS system based on V-MnCoO/Ag nanozyme.

The level of uric acid is crucial to human health. Octahedral oxygen vacancy MnCoO/Ag (V-MnCoO/Ag) nanozyme was successfully prepared by simple hydrothermal, calcination and self-reduction methods. V-MnCoO/Ag nanozyme is rich in Mn/Mn and C/C redox electron pairs, large specific surface area and oxygen vacancies.
