Question: Question: Is lymphocyte inhibition compromised in mesenchymal stem cells from psoriatic skin?
Answer: This study demonstrated abnormalities in MSCs derived from psoriatic skin lesions. We suggest that the attenuated inhibitory effect on T-cell proliferation might be one of the pathogenic mechanisms of psoriasis.

Answer: yes


Question: Question: Is preoperative prolonged steroid use associated with intraoperative blood transfusion in noncardiac surgical patients?
Answer: The effect of prolonged steroid use on bleeding, if any, thus seems likely to be small and is probably of limited clinical consequence. In contrast, corticosteroid use augments the risk of both systemic and wound infections.

Answer: no


Question: Question: Does vP22 significantly enhance enzyme prodrug cancer gene therapy as a part of a VP22-HSVTk-GFP triple fusion construct?
Answer: Based on our results, VP22 fusion proteins do not seem to traffic intercellularly at detectable levels in most tumor cell types. Even though VP22 enhanced cytotoxicity in one cell line in vitro, the effect in vivo was modest. Therefore, our results do not support the utility of VP22 as an enhancer of enzyme prodrug cancer gene therapy.

Answer:
no
