PROBLEM: Question: Does stopcock lumen contamination reflect the full burden of bacterial intravenous tubing contamination : analysis using a novel injection port?
Answer: Effluent culture is a more sensitive marker of IV fluid system contamination than injection port lumen culture. A novel protective device on the stopcock (Port Guide) significantly reduced IV fluid system bacterial contamination.

SOLUTION: no

PROBLEM: Question: Is retinol-binding protein-4 strongly associated with insulin sensitivity in normal pregnancies?
Answer: The increased fat mass and insulin resistance during normal pregnancy was best explained by measures of fat mass. However, the increase in RBP4 from early to late pregnancy, associated with a decline in insulin sensitivity, potentially indicates interactions with glucose metabolism.

SOLUTION: no

PROBLEM: Question: Are methotrexate-loaded lipid-core nanocapsules highly effective in the control of inflammation in synovial cells and a chronic arthritis model?
Answer: The MTX-LNC were better than the MTX solution at reducing proinflammatory cytokines and T-cell-derived cytokines such as interferon-gamma and interleukin-17A. This result, combined with the reduction in the dose required for therapy, shows that MTX-LNC are a very promising system for the treatment of RA.

SOLUTION:
yes
