Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[EX Q]: Question: Does increased endometrial thickness on the day of human chorionic gonadotropin injection adversely affect pregnancy or implantation rates following in vitro fertilization-embryo transfer?
Answer: No adverse effects of a thickened endometrium were demonstrated on implantation, pregnancy, or abortion rates in the first IVF-ET cycle. These findings fail to corroborate with those of Weissman et al. and support those of Yakin et al.
[EX A]: no

[EX Q]: 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.
[EX A]: yes

[EX Q]: Question: Are the effects of high glucose on human endothelial cell growth and gene expression mediated by transforming growth factor-beta?
Answer: These combined observations indicate that (a) endothelial cells exposed to high glucose do not secrete TGF-beta in excess of control cells, (b) there are growth-inhibitory effects of high glucose that are independent of TGF-beta, and (c) high glucose and TGF-beta exert their effects through distinct pathways and at different loci.
[EX A]:
no
