Effects of matrix metallproteinases on dentin bonding and strategies to increase durability of dentin adhesion

open access: yesRestorative Dentistry & Endodontics, 2012
The limited durability of resin-dentin bonds severely compromises the longevity of composite resin restorations. Resin-dentin bond degradation might occur via degradation of water-rich and resin sparse collagen matrices by host-derived matrix ...

Strong and Consistent Social Bonds Enhance the Longevity of Female Baboons [PDF]

open access: yesCurrent Biology, 2010
Longevity is a major component of variation in fitness in long-lived iteroparous species [1-4]. Among female baboons, variation in breeding lifespan accounts for approximately 50% of the variation in lifetime fitness [5, 6]. However, we know little about the causes of variation in longevity in primates or other long-lived mammals. Savannah baboons form
