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.

Q: Question: Is terlipressin more effective in decreasing variceal pressure than portal pressure in cirrhotic patients?
Answer: Our results demonstrate that terlipressin produces significant and prolonged decreases in variceal pressure and variceal wall tension and has intrinsic effects on portal pressure and systemic hemodynamics. Variceal pressure provides a better assessment of the effects of terlipressin administration on esophageal varices than hepatic venous pressure gradient.

A: yes

Q: Question: Does portal venous stasis during liver resection affect platelet aggregability?
Answer: Induced platelet aggregability is not affected by the method of surgical bleeding control used in liver resection. Platelet aggregability seems to be resistant even to portal venous stasis of up to 50 min during Pringle manoeuvre.

A: no

Q: Question: Do identification of UQCRB as an oxymatrine recognizing protein using a T7 phage display screen?
Answer: In this study, using the T7 phage display system, we have identified UQCRB as a direct binding protein of oxymatrine. Furthermore, the specificity and molecular interaction of oxymatrine with UQCRB were also determined. The binding of UQCRB to oxymatrine suggests that UQCRB is a potential target of oxymatrine in treating CHB. These results provide new understanding into the mechanism of oxymatrine and insights into the strategy on the treatment of CHB.

A:
yes
