BACKGROUND & AIMS Osteopenia and increased risk for fractures in IBD result from several factors. AIM OF THE STUDY To investigate the dietary intake of calcium in IBD patients. METHODS A 22-item quantitative validated frequency food questionnaire was used for quantifying dietary calcium in relation to gender and age, in 187 IBD patients, 420 normal- and 276 diseased controls. STATISTICAL ...

1. Forty-two mothers from social classes I, II and III non-manual and twenty-one from social classes III manual M), IV and V were studied longitudinally. The mean daily nutrient intakes in months 4-9 of pregnancy, months 2-4 of lactation and 3 and 6 months post-lactation are presented and are compared with the UK and the US recommended daily allowances (RDA). 2. The quality of the diets (nutrie...

Rumen microbiota has been previously related to phenotypic complex traits of relevance in dairy cattle. The joint analysis the host's genetic background and its can be statistically modelled using similarity matrices between microorganism communities different hosts. Microbiota relationship (K) enable considering whole cumbersome interrelations taxa, rather than analyzing single taxa one at tim...

Insect parasitoids and their insect hosts represent a wide range of parasitic trophic relations that can be used to understand the evolution of biotic diversity on earth. Testing theories of coevolution between hosts and parasites is based on factors directly involved in host susceptibility and parasitoid virulence. We used controlled encounters with potential hosts of the Aphidius ervi wasp to...

Nematode species are widely tolerant of environmental conditions and disperse passively. Therefore, the species richness distribution in this group might largely depend on the topological distribution of the habitats and main aerial and aquatic dispersal pathways connecting them. If so, the nematode species richness distributions may serve as null models for evaluating that of other groups more...

As natural eggs can contribute significantly to overcoming dietary deficits, we have designed and studied the composition of multiple-enriched eggs (Benefic eggs) whose composition is close to the natural egg. They are obtained by feeding laying hens in the usual way, but using additional autoclaved linseed, minerals, vitamins and lutein to provide the extra components. These eggs have greater ...

Arcellinida (testate lobose amoebae) were examined in surface-sediment samples collected 2015 from throughout Harvey Lake, New Brunswick, Canada to assess whether the passage of Post-Tropical Storm Arthur 2014 impacted distribution taxa and assemblages. Cluster analysis non-metric multidimensional scaling (NMDS) revealed four distinct arcellinidan assemblages: (1) Deep Water Reworking Assemblag...

Consecutive tomato monoculture cropping (CTM) obstacles severely restrict the development of facility industry in China. However, effect CTM on soil fungal community greenhouses is still unclear. Here, we aim to identify variation chemical properties and associated with for 1, 3, 5, 9 13 cycles. The results indicated that led a significant increase total phosphorus (TP) electrical conductivity ...

Using the recommended daily allowance (RDA) to assess dietary adequacy implies making a direct comparison between RDA and some measure of dietary intake. The value and usefulness of doing so must clearly depend on the limitations of each. By definition the RDA are intended to cover ‘the average amount of the nutrient, which should be provided per head in a group of people if the needs of practi...
