Neuraxial anesthesia and analgesia provide several advantages over systemic opioids, including superior analgesia, reduced blood loss and need for transfusion, decreased incidence of graft occlusion,… Expand
Antidiabetic effects of Panax ginseng berry extract and the identification of an effective component.
Antihyperglycemic and anti-obese effects of Panax ginseng berry extract and its major constituent, ginsenoside Re, in obese diabetic C57BL/6J ob/ ob mice and their lean littermates were evaluated, suggesting that other constituents in the extract have distinct pharmacological mechanisms on energy metabolism.

Methylnaltrexone for reversal of constipation due to chronic methadone use: a randomized controlled trial.
It is demonstrated that intravenous methylnaltrexone can induce laxation and reverse slowing of oral cecal-transit time in subjects taking high opioid dosages and may have clinical utility in managing opioid-induced constipation. Expand
Ginsenoside Rh2 induces apoptosis and paraptosis-like cell death in colorectal cancer cells through activation of p53.
It is shown that Rh2 exhibited significantly more potent cell death activity than the ginsenoside Rg3 in HCT116 and SW480 colorectal cancer cells, suggesting that the anti-cancer effect of Rh2 can be enhanced by antioxidants. Expand
Tolerability, Gut Effects, and Pharmacokinetics of Methylnaltrexone Following Repeated Intravenous Administration in Humans
This study showed that repeated administration of intravenous methylnaltrexone is well tolerated in humans, with no significant adverse events or changes in opioid subjective ratings and no clinically noteworthy alterations in pharmacokinetics, and suggested that endogenous opioids modulate human gut motility.

Subcutaneous methylnaltrexone may have clinical utility in treating opioid-induced constipation and reducing morphine-induced unpleasant subjective symptoms and pharmacokinetic data after subcutaneous drug injection were studied. Expand
American ginseng: potential structure-function relationship in cancer chemoprevention.
The different ginsenosides in American ginseng, both the naturally occurring compounds and those resulting from steaming or biotransformation are introduced, and the possible structural-function relationship with a focus on sugar molecules, hydroxyl groups and stereoselectivity in gINSenosides is explored.

Crocin from Crocus sativus possesses significant anti-proliferation effects on human colorectal cancer cells.
Data from this study demonstrated that Crocus sativus extract and its major constituent, crocin, significantly inhibited the growth of colorectal cancer cells while not affecting normal cells. Expand
