instruction:
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:
Question: Is early reduction in number of T cells producing proinflammatory cytokines , observed after extracorporeal photopheresis , linked to apoptosis induction?
Answer: Since proinflammatory cytokines play a major role in the pathology of GvHD, their down-regulation post-ECP may produce a direct clinical benefit. The lowest number of IL2-, IFNgamma- and TNFalpha-expressing T cells occurred within the apoptotic population; however, Annexin V-negative T cells also demonstrated a marked reduction post-ECP. However, the lack of an increase in IL4 and IL10 expression indicates that this process was not a consequence of skewing toward a Th2 cytokine profile.
answer:
no


question:
Question: Does high levels of coach intent to integrate a ACL injury prevention program into training translate to effective implementation?
Answer: Coaching workshops can effectively increase coach attitudes, perceived behavioral control, and intent to implement a injury prevention program. However, high levels of behavioral determinants do not appear to translate to high levels of implementation compliance.
answer:
no


question:
Question: Are adolescent Intermittent Alcohol Exposure : Dysregulation of Thrombospondins and Synapse Formation Associated with Decreased Neuronal Density in the Adult Hippocampus?
Answer: Repeated EtOH exposure during adolescence results in long-term changes in specific astrocyte signaling proteins and their neuronal synaptogenic receptor. Continued signaling by these traditionally developmental factors in adulthood may represent a compensatory mechanism whereby astrocytes reopen the synaptogenic window and repair lost connectivity, and consequently contribute to the enduring maladaptive structural and functional abnormalities previously observed in the hippocampus after AIE.
answer:

yes
