TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Transmissible spongiform encephalopathies (TSEs) are neuropathological diseases caused by prions. Prions are infectious particles (PrPSc) which can induce bovine spongiform encephalopathy and most likely also the related infectious disease, variant of Creutzfeldt-Jakob disease (vCJD). The exposure of humans to orally ingested BSE agent in contaminated meat products presumably led to the emergence of vCJD. In vCJD, prions can be detected immunohistochemically not only in neuronal tissue but also in lymphoreticular tissue. vCJD is of significance in transfusion medicine because of the hypothetical transmission of prions by blood products.', 'An immunohistochemistry method was used to allow screening for vCJD in human lymphoreticular tissue.', 'PrPSc can be detected in the cerebrum and cerebellum of patients with sporadic Creutzfeldt-Jakob disease (sCJD) and in the lymph nodes, tonsils, and spleen of vCJD patients. This method has the major advantage of working in fixed specimens which are routinely saved in departments of pathology and therefore allows screening of large numbers of archived human lymphoreticular tissues in different regional areas and from different time points. Scrapie-positive lymphoreticular sheep tissue reacts similarly to human tissue of vCJD affected patients and is available in sufficient amounts to be used as positive control in screening programs.'] Is role of variant Creutzfeldt-Jakob disease for safety of treatment with blood components : screening of lymphatic tissue a potential tool for risk assessment?
OUTPUT:
