Incorporation of L-leucine-14C into proteins and immunoglobulins in vitro was determined in jejunal biopsy specimens from normal volunteers, patients with celiac sprue before and after introduction of gluten into the diet, patients with Whipple's disease in remission, and patients with immune deficiency states.

Usage data is cumulative from December 2021 through December 2022.
Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
