Tissue engineering represents a promising method for generating chondrogenic grafts for reconstructive surgery. In cultured chondrocytes, the dedifferentiation of cells seems unavoidable for multiplication. Stem cells, however, displaying unlimited self-renewal and the capacity to differentiate towards chondrocytes, might be usable after further characterization. As the interactions between the...

Impaired insight is common in psychosis, and is related to poor adherence to treatment regimens. Aleman and colleagues (pp. 204–212) have used meta-analytic techniques to demonstrate that certain cognitive deficits, particularly of executive functions, may be linked with insight. However, these have relatively small effect sizes and the authors highlight the need for research into metacognitive...
