| The aim of the study was to validate the 24-hour recall as a tool for nutrition surveys in Algeria. The reference was the weighing method. The study took place in a rural district of North-Eastern Algeria. The subjects were 50 women of child-bearing age, chosen at random in the district population. The methods, recall and reference, were used to measure food intake over the same two days. We computed differences in paired observations (recall-reference) to detect a level-dependent bias, and a constant bias when the former was absent, and we assessed the precision of the method. We detected a level-dependent bias for lipid, vitamin A and iron intakes. High lipid intake was markedly underestimated with the recall. For vitamin A and iron, the bias was of... |

| Nosema ceranae, a microsporidian parasite originally described in the Asian honey bee Apis cerana, has recently been found to be cross-infective and to also parasitize the European honey bee Apis mellifera. Since this discovery, many studies have attempted to characterize the impact of this parasite in A. mellifera honey bees. Nosema species can infect all colony members, workers, drones and queens, but the pathological effects of this microsporidium has been mainly investigated in workers, despite the prime importance of the queen, who monopolizes the reproduction and regulates the cohesion of the society via pheromones. We therefore analyzed the impact of N. ceranae on queen physiology. We found that infection by N. ceranae did not affect the fat body... |

| Fish unlike terrestrial animals, use a large amount of protein as an energy source for their energy metabolism. When fed on a high protein raiton, the fish itself may choose which amount of protein in food will be converted into body growth and which will be burned through the catabolism. Therefore, in the study one diet was designed with a high protein content and fed to fish with different levels : 0, 5, 15, 25, 35 and 45 g crude protein kg/d. #P. bocourti$ has a higher growth rate than #P. hypophthalmus$ at the same food intake. However, the higher growth observed in #P. bocourti$ is obviously associated to higher fat accumulation in the body. The protein efficiency, NPU and PER, tends to be reduced at higher protein intake in both species. Energy and... |
