question:
Question: Are front-of-pack symbols a reliable indicator of products with healthier nutrient profiles?
Answer: FOP symbols are being used to market foods that are no more nutritious than foods without this type of marketing. Because FOP symbols may influence consumer perceptions of products and their purchases, it may be a useful public health strategy to set minimum nutritional standards for products using FOP symbol marketing.
answer:
no

question:
Question: Do natural triterpenic diols promote apoptosis in astrocytoma cells through ROS-mediated mitochondrial depolarization and JNK activation?
Answer: Overall, we provide a significant insight into the anticarcinogenic action of erythrodiol and uvaol that may have a potential in prevention and treatment of brain tumors and other cancers.
answer:
yes

question:
Question: Do physico-chemical characteristics of lipoplexes influence cell uptake mechanisms and transfection efficacy?
Answer: These findings suggest that, in addition to endocytosis, lipoplexes may enter cell via a temperature-independent mechanism, which could be mediated by lipid mixing. Such characteristics might arise from the specific lipoplex ultrastructure and should be taken into consideration when developing lipoplexes designed for in vivo or ex vivo nucleic acid transfer.
answer:
yes
