Alliesthesia is greater for odors of fatty foods than of non-fat foods
2011
International audience; Alliesthesia is the modulation of the rewarding value of a stimulus according to the internal state (hungry or satiated). This study aimed to evaluate this phenomenon as a function of the nature of the stimulus (odors evoking edible and non-edible items, and the food odors evoking fatty and non-fat foods) and to compare the effectiveness of two reward evaluations (measures of pleasantness and appetence) to reveal alliesthesia. The results showed that both fatty and non-fat food odors were judged as less pleasant and less appetent when the subjects were satiated than when they were hungry, whereas no such difference was observed for non-food odors. There was a greater…
Sensory-specific satiety with simple foods in humans: no influence of BMI?
2007
Olfacto-gustatory sensory-specific satiety plays an important role in the termination of food ingestion. A defect in this mechanism, by increasing food intake, could be a factor in development of overweight. The present study was conducted to explore whether sensory-specific satiety in the overweight may be different from that in normal-weight subjects. 144 subjects (half men, half women; age range: 17–62 years; BMI range: 17–39 kg m−2). Olfactory pleasure (OP) and flavor pleasure (FP) were evaluated before and after ingestion of a single chosen food. Six foods from three classes were offered: cucumber and tomato, pineapple and banana, and peanut and pistachio. According to the subjects' pr…
Alliesthesia in visual and auditory sensations from environmental signals.
2007
'Alliesthesia' describes the fact that sensory stimuli can arouse pleasant or unpleasant sensations according to the internal state of a person. In the present work, the hedonicity aroused by stimuli from the environment in visual and auditory sensations was evaluated in 5 situations: 1) daytime without sensory stimulations (no video-tape); 2) daytime with poor sensory stimulations (uninteresting video-tape film); 3) daytime with rich sensory stimulations (interesting chosen movie on video-tape); 4) night-time without sensory stimulations (no video-tape); 5) night-time with poor sensory stimulations (uninteresting video-tape). During the day, hedonic ratings decreased with time in the no- a…
Reduction of negative alliesthesia for sweet gustatory stimuli by cyproheptadine, a serotonin antagonist
1990
Cyproheptadine (CH) is a serotonin antagonist that increases food intake and body weight. In order to elucidate its mechanism of action on the control of food intake, hunger ratings, pleasure-displeasure to sweet gustatory stimuli and negative alliesthesia induced by a 50 g glucose load were compared in 14 healthy subjects after they had received a placebo or 16 mg of CH. Cyproheptadine did not affect the hunger rating, nor the affective rating in fasted subjects, but it reduced significantly the negative alimentary alliesthesia induced by the glucose load. It was concluded that CH increases food intake more by reducing satiation than by increasing hunger. This is in line with the anti-sero…
Governare il Mezzogiorno. Gli alleati e l'occupazione/liberazione del Sud (1943-1945)
2015
In winter 1943 the United Stated and Britain planned the invasion of Axis-held Europe and decided to invade Sicily. A Military Government (Amgot) – which would be a model for the future Allied administration in Europe – was set in order to administrate the occupied territories. While the Allied propaganda presented the invasion of Italy as a «liberation» from the Axis yoke, when in summer 1943 the Allied troops landed in Sicily, Italy was actually treated as a fully-fledged enemy country. When the Amgot became operative, the contradictory role of the Allies in the occupation emerged clearly. The aim of this article is to examine the complex aspects of this military occupation in Sicily an…
“Gli Alleati sono venuti prima per fare la guerra”. Guerra, emergenza alimentare e conflitto sociale in Sicilia (1943-1945)
2015
La storiografia ha da tempo evidenziato il rapporto tra il crollo delle “basi di massa del fascismo” (Gallerano) e l’incapacità del regime, negli ultimi anni del conflitto, di trovare soluzioni alle difficoltà negli approvvigionamenti. Soprattutto nelle campagne meridionali, fame e miseria – effetti tangibili della guerra totale – determinarono insieme alle sconfitte subite in Africa e ai pesantissimi bombardamenti alleati, una diffusa disaffezione verso il regime. Non a caso, la promessa della fine dei razionamenti e della fame costituì uno degli elementi principali della propaganda anglo-americana in vista dello sbarco del luglio ‘43. E in effetti, nelle parole dei testimoni, al ricordo d…
Hedonic sensations implicated in the control of human food intake : alimentary alliesthesia and sensory-specific satiety
2011
The control of food intake is a complex and multifactorial process controlled by the CNS. It is implicated in the regulation of body weight and the supply of energy substrates, as well as the supply of a panoply of nutrients to cover the specific needs of the organism. Among all the factors involved, hedonic sensations play an important role in guiding food selection and limitation of intake. The theoretical section of this thesis takes into account the physio-anatomical aspects of the control of food intake, in particular sensory pleasure and its evaluation, within the framework of the three principal hedonic phenomena: Conditioned Satiety (CS), Alimentary alliesthesia (AA) and sensory-spe…

Isoëtes todaroana (Isoëtaceae, Lycopodiophyta), a New Species from Sicily (Italy)
2009
Isoetes todaroana, a new species from western Sicily (Italy), is described. Morpholog- ical, anatomical and ecological characters are given. The main differential characters are the presence of only two leaf air chambers, rather than four as in all other known species of the genus, and the shape of the scales, which have two lateral rounded lobes and one central spine-like lobe, together with its peculiar calcophilic habitat. So far, the species is known from a single locality.
Mechanisms involved in the control of feeding behavior in relation to food flavor
2016
Revue; IntroductionIntake is one of the most essential behaviors, since human beings, like any living organism, require adequate nutrients for their survival. Ingestive behavior is controlled to maintain energy balance by peripheral and central mechanisms. When physiological needs are not being met, they will lead to motivation. Thus, being hungry will motivate us to find food, and the motivation will cease when needs are met. Ingestive behavior is thus initially due to a need related to internal signals (Fig. 10.1), in this case, hunger (physiological need) and appetite (urge to eat a food from which we expect pleasure and satisfaction). Sensory (visual, olfactory and, to a lesser extent, …
