Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor mediating the adverse effects of dioxins and polycyclic aromatic hydrocarbons (PAHs). In this study, we investigated the genetic-, time-, dose-, species- and tissue-dependent AhR-mediated agonistic/ antagonistic activities of three food flavonoids: quercetin, chrysin and genistein. To that end, four stably transfected cell lines were used in cell-based luciferase reporter gene assays: three lines were transformed with the ptKLuc vector harbouring four dioxinresponsive elements (DREs) upstream of the thymidine kinase promoter and the luciferase gene (HepG2-Luc, T-47D-Luc and H4IIE-ULg). The fourth is a patented cell line transformed with a different construct: H4IIE DR-CALUX®. Both H4IIE cells were compared for their genetic construction. Human hepatoma (HepG2-Luc) and human breast tumour (T-47D-Luc) cells were compared for tissue-dependent effects. Rat hepatoma (H4IIE-ULg) and human hepatoma (HepG2-Luc) cellswere compared for species-dependent activities.We concluded that quercetin, chrysin and genistein act in a time-, dose-, species- and tissue-specific way. For example, genistein displayed agonistic activities when exposed to rat hepatoma cells during 6h but not after 24 h. Flavonoids displayed agonistic/antagonistic activities in human breast tumour cells, depending on the exposure time, while in human hepatoma cells, only antagonistic activities of flavonoids were measured. In addition, we report, in all the cells, a synergy between an isoflavone and two food contaminants; the 2,3,7,8-tetrachlorodibenzop- dioxin and 3-methylcholanthrene, a PAH. In rat cells, this synergy occurred when cells were exposed to flavonoids and contaminant for 6h, while it was observed in human cells only after 24 h. [less ▲]

Introduction: Kashin-Beck disease (KBD) is a bone and joint pathology. KBD begins during childhood, causes deformities, pain, lack of mobility, and short stature. The pathophysiology of the disease is unknown. Nutrition possibly plays a role. Children living in KBD endemic areas in Central Tibet present severe growth retardation, signs of chronic malnutrition and a high prevalence of rickets. A food consumption study was conducted. We have focused our attention on total energy intake, calcium, phosphorus and vitamin D. Material and methods: Prospective food intake measurements have been performed. The investigation concerned children from 9 to 16 years old living in KBD endemic areas. All food and drinks have been measured during several days at the 4 seasons of the year. Anthropometric data were obtained. Results: 30,5% of the children presented with stunting (height for age ratio below -2 z score); 13,8% of the cohort suffered from acute malnutrition (body mass index below -2 z score). Mean total energy intake was 87% of the recommended value. Calcium and vitamin D intakes never covered the needs (44 % and 14 %, respectively). Phosphorus intake was high. Mean Ca / P ratio was 0.54. Conclusion: Calcium and vitamin D deficiency may play a role in the etiology of bone and joint diseases in this population. To improve the nutritional status of the children, a large program of calcium and vitamin D supplementation among 0 - 5 years old children living in KDB endemic areas was started. Besides, chemical analyses of locally grown foods are performed, in order to have a more precise evaluation of nutrient intake. In the future, the effect of increased energy intakes will be evaluated. [less ▲]

Several species of kingfisher occur on Lake Nokoué, southern Bénin, including Malachite (Alcedo cristata) and Pied Kingfishers (Ceryle rudis). Here, we compare their diet and estimate the degree of overlap in food niche by analysing contents of regurgitated pellets collected near nesting sites of Pied Kingfishers or inside the nest chambers of Malachite Kingfishers. Characteristic fish skull bones were identified using a reference collection of local fish skeletons. Malachite Kingfishers feed most frequently on fish that occur around floating vegetation, mainly Kribia sp. (56%), Hemichromis fasciatus (28%) and Sarotherodon melanotheron (8%). Important differences were found between different pairs, and between adults and nestlings, the latter being fed almost exclusively on Kribia sp. Larger fish are fed to nestlings than are eaten by the adults. Pied Kingfishers prey upon 14 different fish species, some of them being caught in the pelagic region of the lake, particularly clupeids taken by hovering. By comparison with Malachite Kingfishers, Pied Kingfishers feed on a wider diversity of prey, and take larger fish, so that the dietary overlap between the species is relatively low (O = 0.181).

Ichthyoplankton samples were collected from 19 to 31 January 2004 in the Dumont d’Urville Sea (East Antarctic shelf). The Nototheniidae Pleuragramma antarcticum comprised more than 90 % of the sampled larvae. Gut contents of 95 P. antarcticum larvae were examined. Most larvae fed on phytoplankton, especially diatoms, whereas some other specimens had a mixed diet with phyto- and zooplankton prey. A single specimen fed exclusively on copepods. The stomach contents was dominated by three diatoms taxa, such as Thalassiothrix antarctica, Fragilariopsis spp. and Chaetoceros spp. Prey selection was apparently food density dependent, with an inverse relationship between food abundance and selection feeding. Larvae selected positively some diatoms, such as Coscinodiscus spp. and T. antarctica, presenting a low concentration in the water column compared to Fragilariopsis spp., which were strongly negatively selected. During summer, larvae were opportunistic feeders with a broad trophic niche, which allowed them to switch between different food types. [less ▲]

Most previous research on nonhuman primates reported increased levels of agonistic behaviors associated with food provisioning by humans. To further investigate the permanence of this effect of increased social competition in long-term commensal-living primates, we examined the immediate impact of food provisioning on agonistic behavior rates in a commensal population of long-tailed macaques (Macaca fascicularis) at Uluwatu Temple, Bali (Indonesia). We compared proportions of agonistic behaviors between various food provisioning levels defined by the absence/presence and the quantity of food provisioned. We collected data using focal and scan sampling methods during a four-month study period (June to October 2010). We performed non-parametric statistical tests (Wilcoxon Test & Friedman Test; p < .05) on a population sample of 66 individuals. Results did not show obvious impact of provisioning on agonism rates, nor increase of potential appeasement strategies such as sexual behaviours, grooming or self-directed behaviours, often associated with the presence of provisioned food. These data suggest that the long-tailed macaques at Uluwatu Temple are responding effectively to high provisioning level, that is, without increasing social competition. We hypothesize that the high spatiotemporal abundance of human food, associated with the species’ eco-behavioural flexibility and the long term story of human-macaque commensal relationships in Uluwatu may explain the absence of provisioning impact on agonistic rates.

Numerous works are related to the use of unconventional feed resources, and particularly to Mucuna Spp., in poultry diet. This review aims at describing the context of their use, their nutritional values and the constraints related to their upgrading, before considering the effects of the various methods of treatment on the reduction of the toxic substances that they could contain and on their chemical compositions. The methods of treatment are very variable and their standardisation should allow using them in rural area. Those feed could thus constitute an alternative to costly conventional feed usually used in poultry production. [less ▲]

Throughout history, there have been periods of civil unrest. From religious wars to wars of conquest, historians believe that the causes of wars are closely related with religious, political or economic reasons. But when we discuss about civil unrest inside a country with the power of transforming it into a civil war and expanding at regional level, the triggering factors have yet to be discovered. From the period of the Qing Dinasty (1644-1911) in China to the Great Depression in the 1930s in the USA or the beginning of the second World War in France, these periods have two common points: civil unrest and food shortages.
