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.

Question: Are flexible magnets effective in decreasing pain perception and recovery time after muscle microinjury?
Answer: No significant therapeutic effects on pain control and muscular dysfunction were observed in subjects wearing flexible magnets.
no

Question: Is resistive heating more effective than metallic-foil insulation in an experimental model of accidental hypothermia : A randomized controlled trial?
Answer: Resistive heating more than doubles the rewarming rate compared with that produced by reflective metal foil and does so without producing an afterdrop. It is therefore likely to be useful in the prehospital setting.
yes

Question: Is plasmin protective in experimental renal interstitial fibrosis?
Answer: Plasminogen, the key proenzyme in the plasminogen-plasmin system, does not protect mice from experimental interstitial fibrosis and may have significant pathogenetic effects. These findings, together with other recently published studies in the biology of renal fibrosis, imply that effects of proteins such as plasminogen activator inhibitor-1 (PAI-1), tissue-type plasminogen activator (tPA), and urokinase-type plasminogen activator receptor (uPAR) on renal fibrosis occur independently from the generation of plasmin.

no
