BACKGROUND Flavor perception, the integration of taste and odor, is a critical factor in eating behavior. It remains unclear how such sensory signals influence the human brain systems that execute the eating behavior. METHODS WE TESTED CEREBRAL BLOOD FLOW (CBF) IN THE FRONTAL LOBES BILATERALLY WHILE SUBJECTS CHEWED THREE TYPES OF GUM WITH DIFFERENT COMBINATIONS OF TASTE AND ODOR: no taste/no ...

The current series of experiments investigated the effects of the timing of gum chewing on cognitive function, by administering a battery of cognitive tasks to participants who chewed gum either prior to or throughout testing, and comparing their performance to that of controls who did not chew gum. Chewing gum was associated with performance advantages on multiple measures when gum was chewed ...

Chewing gum allergy is a rare condition in emergency settings. A 48-year-old man presented to the emergency department with generalised itchiness which was more prominent on the periorbital areas, nausea, vomiting, and dyspnoea after taking chewing gum. Vital signs showed hypotension with a blood pressure of 72/45 mmHg, and heart rate 95 beats per minute. Auscultation of the chest revealed diff...

Postoperative gastrointestinal dysfunction remains a source of morbidity and the major determinant of length of stay after abdominal operation. There are many different reasons for postoperative gastrointestinal dysfunction such as stress response, perioperative interventions, bowel manipulation and so on. The mechanism of enhanced recovery from postoperative gastrointestinal dysfunction with t...

Background & aim: Cesarean section (CS) accounts for 35% of all surgical operations in Iran. Post cesarean ileus is a complication of CS. There are various pharmaceutical and non-pharmaceutical ways for the treatment of this condition. Given the fact that the non-pharmaceutical approaches are better tolerated and often inexpensive, the present study was conducted to evaluate the effect of chewi...

BACKGROUND Enhanced recovery, in part, aims to reduce postoperative gastrointestinal dysfunction (PGID). Acquired - or established- vagal dysfunction may contribute to PGID, even for surgery not involving the gastrointestinal tract. However, direct evidence for this is lacking. We hypothesized that chewing gum reduces morbidity (including PGID) by preserving efferent vagal neural activity posto...

BACKGROUND The goal of this prospective study was to estimate the absorbed (radiation) doses to salivary glands in radioiodine therapy of thyroid cancer under chewing-gum stimulation using (124)I positron emission tomography (PET)/computed tomography (CT) imaging. METHODS Duplex ultrasonography was conducted in three test persons for visual comparison of the glandular blood flow with three di...

background: chewing sugar-free gums is a convenient way to increase salivary flow. salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli, and chewing gum can provide both of these stimuli. the aim of this study was to compare the effect of five different flavors of sugar-free chewing gum on the salivary flow rate (sfr) and ph. materials and methods: fift...

This study tests the hypothesis that chewing gum leads to cognitive benefits through improved delivery of glucose to the brain, by comparing the cognitive performance effects of gum and glucose administered separately and together. Participants completed a battery of cognitive tests in a fully related 2 x 2 design, where one factor was Chewing Gum (gum vs. mint sweet) and the other factor was G...
