Q: Question: Does [ Histology accurately predict the clinical behaviour of bronchopulmonary carcinoids - results from an Icelandic population-based study ]?
Answer: BPCs usually behave as benign neoplasms, with excellent long-term survival after surgical removal. Metastases are more common in patients with atypical histology (40%), and their survival is worse. However patients with typical histology can metastasize (14.8%) and die from the disease. Therefore, histology (typical vs. atypical) can not be used with certainty to predict the clinical behaviour of these tumors.

A: no

Q: Question: Does tNF-α suppression and osteoprotegerin overexpression inhibit wear debris-induced inflammation and osteoclastogenesis in vitro?
Answer: Lenti-siTNFα-OPG can inhibit the wear debris-induced inflammatory responses and osteoclastogenesis in vitro, and may represent a promising therapeutic candidate for the treatment or prevention of wear particle-induced osteolysis.

A:
yes
