New Strategy Could Thwart Periodontal Disease Progress

A new study suggests that blocking a specific molecular receptor on white blood cells could prevent periodontitis from developing, as well as halting the progression of the disease once it has already developed. More...

Aged Cells Retain Capacity for Rejuvenation via Enhanced Extracellular Support

Researchers have found that aged human skin fibroblasts retain their capacity for a high degree of reactivation and that this capacity can be significantly restored simply by enhancing the aged extracellular structural support. More...

Hormone Therapy Response Associated with Signaling Activity in Circulating Cancer Cells

A study monitoring hormone receptor activity in tumor cells from patients being treated for resistant metastatic prostate cancer has found that such monitoring may be useful for indicating which patients will be more likely to respond well to continued therapy. More...
