In a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of aging are normal or red flags for disease, scientists are describing how the protein content of women's saliva change with advancing age. The discovery could lead to a simple, noninvasive test for better diagnosing and treating certain age-related diseases in women, they suggest in a report in ACS' Journal of Proteome Research. These diseases include lupus, Sjögrens syndrome (associated with dry mouth and dry eye), and other immune-related disorders that affect millions of women worldwide, often at higher rates than in men.
