Usage Information
Abstract
Androgen was given to male rats to determine if it exerted effects on the aortic wall distinct from those of estrogen deficit. Although a general anabolic effect was avoided, significant vascular effects were observed. The amounts of mural fibrous proteins, elastin and collagen, were significantly increased in treated animals; noncollagenous, alkali-soluble protein, thought to reflect the cellular component, was unchanged with treatment. These effects were not detectable on microscopic examination and measurement of the vessel wall despite attempts to duplicate closely in vivo wall dimensions before study. These findings of distinct and marked effects of androgen on vascular metabolism extend the growing evidence for an important role of sex hormones in vessel wall structure and function.

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.
