question:
Question: Does resident participation affect surgical outcomes , despite introduction of new techniques?
Answer: In the context of this single surgical operation, resident participation does not substantially affect major complication rates. The common residency training paradigm provides clinical experience and supervision without necessarily impacting patient safety. Analysis of additional operations in different settings will be necessary.
answer:
no

question:
Question: Does wNT2 promote Cervical Carcinoma Metastasis and Induction of Epithelial-Mesenchymal Transition?
Answer: WNT2 might be a novel predictor of PLNM and a promising prognostic indicator in cervical cancer.
answer:
yes

question:
Question: Does hypoxia interfere with connective tissue growth factor ( CTGF ) gene expression in human proximal tubular cell lines?
Answer: We provide evidence that hypoxia inhibits CTGF synthesis in human proximal tubular epithelial cells, involving HIF-1alpha. Under hypoxic conditions, induction of CTGF by TGF-beta was repressed. The reduced synthesis of the profibrotic factor CTGF may contribute to a potential protective effect of hypoxic preconditioning in acute renal injury.
answer:
yes
