Puerarin, an isoflavone C-glycoside, has been identified as the major active component isolated from Pueraria lobata (Kudzu) responsible for suppression of alcohol drinking. In order to conduct clinical studies of Kudzu's efficacy, a method for measuring its bioavailability and pharmacokinetic profile is needed. We have developed a gradient reversed-phase(More)
BACKGROUND AND PURPOSE High blood pressure (BP) in acute stroke is associated independently with a poor outcome. Recent evidence suggests that other hemodynamic parameters may also be associated with outcomes following stroke. METHODS The relationship between baseline BP, heart rate, and other hemodynamic parameters, and early outcomes were assessed using(More)
BACKGROUND Number-needed-to-treat describes the magnitude of the effect of an intervention, underpins health economic analyses, and is typically calculated for binary events. Ordered categorical outcomes provide more clinical information and their analysis using ordinal approaches is usually more efficient statistically. However, to date, techniques to(More)
OBJECTIVES This study was undertaken to assess the pharmacokinetic profile of puerarin, the major isoflavone found in a kudzu (Pueraria lobata) extract after acute and repeated administration. METHODS Participants were given either single or repeated doses of kudzu extract, and blood samples were collected for either 8 or 72 hours for subsequent(More)
Research suggests that individuals may differ in their susceptibility to false memory in the Deese/Roediger and McDermott procedure. Prior studies of differences have focused on the effects of age, personality, personal past history of abuse, and neurological status on false memory susceptibility. This study examined whether sex might also differentially(More)
We previously demonstrated that short-term treatment with a standardized kudzu extract (NPI-031) reduced alcohol drinking by men and women in a natural setting. The present study was conducted in nontreatment-seeking heavy drinkers to assess the safety and efficacy of 4 weeks of kudzu extract in an outpatient setting. This randomized between-subject,(More)
We searched the MEDLINE, CINAHL, and Cochrane Library databases for articles published between January 1995 and April 2011. The update of this clinical practice guideline is the result of reviewing a total of 54 clinical trials and systematic reviews on incentive spirometry. The following recommendations are made following the Grading of Recommendations(More)
BACKGROUND Blood pressure (BP)-lowering trials studying efficacy mostly assesses binary outcome events, for example stroke/no stroke. Analysis of ordered categorical vascular events (e.g. three levels: fatal stroke/nonfatal stroke/no stroke) provides information on severity and is more powerful statistically than analyses using binary data, as used in(More)
