Oxygen consumption of burbot, Lota lota(L.), fed different rations of vendace, Coregonus albula L.
2000
Summary The oxygen consumption of adult burbot, Lota lota (L.), was examined to determine the effects of fasting and meal ration on oxygen consumption rates. The temperature (2.1 °C) was selected to represent ambient conditions for burbot in winter. The average pre-feeding oxygen consumption rate was 29.5 mg kg−1 h−1. Feeding affected the oxygen consumption rates since the apparent heat increment correlated significantly with the meal ration. However, the meal ration (i.e. vendace, Coregonus albula L.) did not affect the proportion of the ingested meal energy used in the apparent heat increment. When the meal ration was increased, peak oxygen consumption ranged from 1.2 to 2.2 times higher …
Satiety in face of variety: On sensory-specific satiety and perceived food variety
2013
Sensory-specific satiety (SSS) is the relative decrease in sensory pleasure derived from a specific food or drink with its consumption. Such satiation does not require ingestion, but hinges on exposure to a given flavour. As it affects meal termination, it is important in determining overall intake. Variety in a meal or dish undermines SSS and promotes consumption of the meal. In the present study, the hypothesis that the mere presentation and suggestion of food variety can undermine SSS was examined in a sample of 92 undergraduate students. All participants ate several bite-sized servings of a test food to induce SSS, but participants in the experimental group were shown another food durin…
Food choices and environmental responsibility – protect the Baltic Sea
2012
‘The Baltic environment, food and health: from habits to awareness – FOODWEB’ is a project that aims to raise public awareness about the links between food quality and its origin, focusing on the Baltic Sea and its surroundings. Cultivation of food for humans and related production activities can impact negatively on the Baltic Sea, and aquatic food products from the Baltic Sea may cause problems to humans as a result of toxins in the marine environment. This is a circular problem in the Baltic ecosystem. The project is a part of Central Baltic IVA Programme 2007- 2013. Finland, Estonia and Latvia take part in the Foodweb-project. The population is projected to grow in Finland and decrease …
Dynamics of Aroma Release during Cheese Consumption
2014
The influence of satiation before and after a pasta meal was studied through the evaluation of aroma release and chewing activity during the consumption of a flavored model cheese. Aroma release during cheese consumption was found to be higher after satiation than before. The difference can be explained by an increase in the duration of the chewing sequence and an increase in the chewing muscular work after satiation. However, the pulmonary flow was not affected by satiation.
The diagnosis and management of gastric cancer: Expert discussion and recommendations from the 12th ESMO/World Congress on Gastrointestinal Cancer, B…
2011
Well-recognized experts in the field of gastric cancer discussed during the 12th European Society Medical Oncology (ESMO)/World Congress Gastrointestinal Cancer (WCGIC) in Barcelona many important and controversial topics on the diagnosis and management of patients with gastric cancer. This article summarizes the recommendations and expert opinion on gastric cancer. It discusses and reflects on the regional differences in the incidence and care of gastric cancer, the definition of gastro-esophageal junction and its implication for treatment strategies and presents the latest recommendations in the staging and treatment of primary and metastatic gastric cancer. Recognition is given to the ne…
Effects of differential relevance of external stimuli on heart rate under food deprivation
1972
Ss were deprived of food for 24 h, after which heart rate (HR) was recorded with food placed before the Ss and also after they had eaten it. It was predicted, according to Malmo’s interaction hypothesis, that HR in both situations would be higher than at a control level but that the increase after food ingestion would be greater than that found in the presence of visual cues. The results did not wholly support these predictions. Only after eating were significant HR increases found. Possible reasons for the discrepancies between findings in this area were discussed.

Transfer of Water and Volatiles at Interfaces: Application to Complex Food Systems
2013
International audience; During processing, storage and consumption, mass transfer of various small molecules (water, gases, flavour compounds or other solutes) occurs between the different phases in complex food products, or between complex food and its surroundings. These mass transfers can lead to physical or chemical changes and thus induce food quality modifications.The objective of this paper is to better understand the behaviour of small molecules at the interfaces, especially in model heterogeneous food systems. Different techniques have been designed to characterize mass transfers of these small molecules and their effects on food properties. In particular, techniques such as rotati…
Testing the assumptions of conditional handicap theory: costs and condition dependence of a sexually selected trait
2000
Conditional handicap models of sexual selection predict that sexual traits are reliable signals of male quality because they are (a) condition dependent and (b) costly to produce or maintain. In this study, my objective was to experimentally investigate whether the drumming of male Hygrolycosa rubrofasciata wolf spiders is a condition-dependent costly trait. Males court females by drumming dry leaves with their abdomen and females preferentially mate with males drumming at higher rates. I manipulated male phenotypic condition and drumming rate simultaneously by keeping males on three different food rations and either introducing or not introducing them to a female. Food ration treatment aff…
Virus entéricos humanos en alimentos: detección y métodos de inactivación
2020
[ES] Los principales patógenos víricos que podemos adquirir ingiriendo alimentos contaminados son los norovirus, el virus de la hepatitis A y el virus de la hepatitis E que se propagan principalmente a través de la vía fecal oral. En los últimos años, la incidencia de brotes de transmisión alimentaria causados por estos patógenos ha experimentado un aumento considerable, en parte debido al comercio globalizado y a los cambios en los hábitos de consumo. Las matrices alimentarias que mayor riesgo representan para el consumidor son los moluscos bivalvos, vegetales de IV gama, frutas tipo baya y platos listos para comer. Actualmente las técnicas moleculares son las más habituales para la detecc…
