question:
Question: Does acute ethanol always affect delay discounting in rats selected to prefer or avoid ethanol?
Answer: Our data indicate that in these lines of animals, alcohol preference or avoidance has no impact on delay discounting following acute ethanol exposure. It is possible that other genetic models or lines may be differentially affected by alcohol and exhibit qualitatively and quantitatively different responses in delay discounting tasks.
answer:
no


question:
Question: Does lactobacillus plantarum 299v reduce enteric bacteria or bacterial translocation in patients undergoing colon resection?
Answer: Lactobacillus plantarum 299v was established in the intestine, but no inhibitory effect on enteric bacteria, bacterial translocation, or postoperative complications was found. The mechanism behind the protective effects of probiotics found in animal and some human studies remain elusive and require further explorations. No adverse effects were recorded after the administration of high doses of Lactobacillus plantarum 299v.
answer:
no


question:
Question: Are dendritic cells generated from patients with androgen-independent prostate cancer impaired in migration and T-cell stimulation?
Answer: Our data suggest that MoDCs from patients with androgen-independent CaP are functionally intact and hence qualify as cellular vaccines for immunotherapy of advanced stage CaP.
answer:

no
