Individualized Piano Instruction for Improving Cognition in Breast Cancer Survivors.

Purpose: To evaluate the use of individualized piano instruction (IPI) for improving cognition among breast cancer survivors.

Participants & Setting: Six participants were included in an eight-week piano program with three data collection time points at baseline, midpoint, and postintervention. Participants were recruited from the breast cancer clinic of a university cancer center in South Florida.

Sex differences in preferences for humor: a replication, modification, and extension.

Evolutionary-minded scientists have proposed that humor is a sexually selected trait in men that signals mate quality. Indeed, women tend to prefer men who make them laugh and men tend to prefer women who laugh at their jokes. However, it is unclear how robust this pattern is.

A compressive strength study of complete ceramic crowns. Part II.

The original study by this group compared the crushing strength of Cerestore crowns with porcelain-fused-to-metal crowns and porcelain jackets. Since that time, two porcelains, Dicor and Renaissance, have become available. This study compares Cerestore, Dicor, and Renaissance crowns using a porcelain-fused-to-metal crown as a standard for the type of crown with maximum strength that is currently available and an all-porcelain crown to represent the porcelain with the least strength.

A compressive strength study of an all-ceramic crown.

Eighteen crowns were subjected to the same occlusal loading. The porcelain-fused-to-metal crown was more than twice as resistant to the load than the Cerestore crown and almost four times stronger than the porcelain crown. These tests show that porcelain fused to metal has demonstrated its capability as a strong posterior restoration.
