Negative anticipatory contrast (NAC) corresponds to the suppression in consumption of a first rewarding substance (e.g., saccharin 0.15%) when it is followed daily by a second preferred substance (e.g., sucrose 32%). The NAC has been interpreted as resulting from anticipation of the impending preferred reward and its comparison with the currently available first reward [Flaherty, C.F., Rowan, G...

Artificially sweetened beverage consumption has been linked to obesity, and it has been hypothesized that considerable exposure to nonnutritive sweeteners may be associated with impaired energy regulation. The reward system plays an integral role in modulating energy intake, but little is known about whether habitual use of artificial sweetener (i.e., diet soda consumption) may be related to al...

BACKGROUND There has been a dramatic escalation in sugar intake in the last few decades, most strikingly observed in the adolescent population. Sugar overconsumption has been associated with several adverse health consequences, including obesity and diabetes. Very little is known, however, about the impact of sugar overconsumption on mental health in general, and on reward-related behavioral di...

The commensal bacteria Lactobacillus are widely used as probiotic organisms conferring a heath benefit on the host. They have been implicated in promoting gut health via the stimulation of host immunity and anti-inflammatory responses, as well as protecting the intestinalmucosa against pathogen invasion. Lactobacilli grow by fermenting sugars and starches and produce lactic acid as their primar...

Leptin receptors are present in taste buds and previous research indicates that leptin administration modified electrophysiological and behavioral responses to sweet taste. It is now known that sweet taste is temperature dependent. We examined the influence of (1) stimulus temperature on chorda tympani (CT) nerve responses to sucrose, saccharin and NH(4)Cl; and (2) leptin administration on CT n...

Back Cover: In this cover, cats (diene monomers) enjoy playing with the special ball (saccharin methacrylamide). They are combined together in alternating fashion to become like a giant cord. Herein, subsequent transformation makes balls shiny, and seem be satisfied connection mysterious toy. The cord is relatively soft because flexible. This cover picture associated article number 2100249 by M...

The effect of sodium saccharin fed to male F344 rats at levels of 5.0, 2.5, 1.0, 0.5, and 0.1% of the diet for 10 weeks was evaluated by autoradiography and scanning electron microscopy. A dose response was evident with both techniques. The labeling index was statistically significantly elevated at all doses above 0.1%. As observed by scanning electron microscopy, the number of foci containing ...
