Question: Question: Does local lymph node involvement predict poor outcome in pediatric renal cell carcinoma?
Answer: Children with lymph node-positive RCC in the absence of distant metastatic disease had a relatively favorable long-term prognosis, with survival rate nearly triple those of adult historical controls. Until highly effective therapies for RCC are identified, these children should not be exposed to adjuvant treatment. Further investigation of the biologic differences between adult and pediatric RCC is warranted.

Answer: no

Question: Question: Does fasting induce impairment of gastric mucosal integrity in non-insulin-dependent diabetic ( db/db ) mice?
Answer: These findings indicate that fasting-induced glucose deficit causes gastric mucosal lesions and increases the susceptibility of gastric mucosa to noxious agents owing to the loss of mucus glycoprotein in db/db mice. Prolonged diabetes is likely to augment the severity of fasting-induced impairment of the gastric mucosal function.

Answer:
yes
