Ascorbic acid metabolism in castrated rats.
TL;DR: In castrated rats there was an appreciable decrease in the ascorbic acid and dehydroascorbic acid contents of the liver, while on the other hand, there was a significant increase in the diketogulonic acid content of liver.

Ascorbate-dependent expression of ubiquitin genes in guinea pigs
TL;DR: In an attempt to characterize a gene(s), of which the expression is ascorbate-dependent, a cDNA fragment encoding ubiquitin was isolated from a subtracted cDNA library constructed from spleen RNAs of as Corby-deficient or -replete guinea pigs, the ubiX gene was expressed animal-dependently.

TL;DR: In this paper, the authors used colorimetric detections of DPPH and ORAC, ESR-ST methods were employed for evaluating antioxidant ability, which can determine scavenging activities against naturally-occurring ROS i.e. superoxide anion radical (·O2−), hydroxyl radical (HO·), alkoxyl radical(RO·) and singlet oxygen (1O2), individually.
