Objective This in situ study investigated the ability of a CPP-ACP chewing gum in preventing erosive enamel loss. Material and Methods: During three experimental crossover phases (one phase per group) of seven days each, eight volunteers wore palatal devices with human enamel blocks. The groups were: GI - Sugar free chewing gum with CPP-ACP; GII - Conventional sugar free chewing gum; and GIII -...

Two experiments re-examined whether chewing spearmint gum affects initial word learning and/or immediate recall for a word list. Both experiments failed to show effects of chewing gum at learning or recall, nor did they suggest that chewing gum produces a context-dependent memory effect. This was true when extraneous contextual cues at learning and recall were minimised (Experiment 2). Together...

Two experiments examined whether chewing spearmint gum can affect the initial learning or subsequent recall of a word list. Comparing those participants in Experiment 1 who chewed gum at the learning or the recall phases showed that chewing gum at initial learning was associated with superior recall. In addition, chewing gum led to context-dependent effects as a switch between gum and no gum (o...

Medicated chewing gum has been recognised as a new advanced drug delivery method, with promising future. Its potential not yet fully exploited because currently there is no gold standard for testing the release of agents from in vitro. This study presents novel humanoid robot capable closely replicating human motion closed environment, incorporating artificial saliva and allowing measurement xy...

The proposition that chewing gum can improve alertness was investigated via both physiological and self-rated measures. The Pupillographic Sleepiness Test (PST) provided a measure of pupillary unrest (PUI); a physiological index of daytime sleepiness. Chewing gum reduced the extent of sleepiness as measured by both PUI and self-rated sleepiness. Specifically, in comparison with sham chewing and...

RATIONALE Recent research suggests that chewing gum may increase alertness and lead to changes in cognitive performance. The present study examined effects of chewing gum on these functions within the context of a single study. OBJECTIVES This study had four main aims. The first was to examine whether chewing gum improved learning and memory of information in a story. The second aim was to de...

The experiment examined the prediction that chewing gum at learning and/or recall facilitated subsequent word recall. Chewing gum at learning significantly impaired recall, indicating that the chewing of gum has a detrimental impact upon initial word encoding. In addition, a context-dependent memory effect was reported for those participants who both learned and recalled in the absence of gum; ...

HYPOTHESIS Gum chewing after elective open colon resection may stimulate bowel motility and decrease duration of postoperative ileus. DESIGN AND SETTING Prospective, randomized study in a community-based teaching hospital. PATIENTS Thirty-four patients undergoing elective open sigmoid resections for recurrent diverticulitis or cancer. MAIN OUTCOME MEASURES First feelings of hunger, time t...
