Ex Input:
Question: Is dietary docosahexaenoic acid-induced generation of liver lipid peroxides suppressed further by elevated levels of glutathione in ODS rats?
Answer: Higher than normal levels of dietary methionine are not necessarily associated with decreased dietary DHA-induced generation of tissue lipid peroxides and VE consumption except that the GSH requirement is increased in a condition such as acetaminophen feeding.

Ex Output:
no

Ex Input:
Question: Are ethnic variations in uterine leiomyoma biology caused by differences in myometrial estrogen receptor alpha levels?
Answer: Neither on a transcriptional nor on a protein level were there statistically relevant differences in steroid hormone receptor levels. A causative role for these receptors in the ethnic variation of leiomyoma biology seems unlikely.

Ex Output:
no

Ex Input:
Question: Does preoperative transarterial chemoembolization increase hepatic artery complications after liver transplantation : A single center 12-year experience?
Answer: Our single institution experience showed that it might be safe to perform pre-TACE in HCC patients before OLT. It would not increase postoperative HAC risk.
