due to poor solubility in lipids, many of bioactive components (nutraceutical materials) show less bioactivity than optimal state in water solution. phytosomes improve absorption and bioavailability of biomaterials. liposomes, spherical shaped nanocarriers, were discovered in the 1960s by bangham. due to their composition, variability and structural properties, liposomes and phytosomes are extr...

the mobility and bioavailability of trace elements in the agricultural soils are extremely important in assessing the risk of toxicity to the growing plants. a five step sequential extraction procedure (sep) has been employed to study the speciation of as, sb, cr, cu, cd, pb, zn, ni, fe and mn in 18 soil samples neighboring an industrial complex in isfahan, central iran. enrichment factor (ef) ...

Korean ginseng (Panax ginseng C.A. Meyer) was tested to demonstrate that production of this plant with a nutritionally important selenium (Se) is possible, making it a functional ginseng with concentrated Se supplement and the Se incorporated into the enriched Korean ginseng occurs in a soluble, metabolically available form. Sequential extraction was used to assess the degree of solubility of S...

OBJECTIVE To understand the relative contributions of breast milk and the weaning diet to overall nutrient intake, with a view to designing and implementing appropriate programmes to improve complementary feeding in developing countries. METHODS Complementary food intake was measured in a sample of 250 toddlers (mean baseline age: 13.9 +/- 2.4 months) using 24-h dietary recall interviews admi...

As a key nutrient, nitrogen can limit primary productivity and carbon cycle dynamics, but also evolutionary progress. Given strong redox-dependency of its molecular speciation, environmental conditions control localization bioavailability. This particularly applies to periods in Earth history with frequent redox fluctuations, such as the Neoproterozoic. We here report on chlorophyll-derived por...

Functional foods are foods that, by nature or design, can deliver benefits beyond that of sustenance. They bridge the traditional gap between food and drugs, offering consumers greater opportunity to take their health care into their own hands. Rapidly increasing knowledge of the physiological effects of nutrients and their potential health benefits offers exciting prospects for the food indust...

Nutrient management is always a great concern for better crop production. The optimized use of nutrients plays key role in sustainable production, which major global challenge as it depends mainly on synthetic fertilizers. A novel fertilizer approach required that can boost agricultural system production while being more ecologically friendly than As nanotechnology has left no field untouched, ...

BACKGROUND Our objective was to determine if a biofortified variety of black bean can provide more bioavailable-iron (Fe) than a standard variety. Two lines of black beans (Phaseolus-vulgaris L.), a standard (DOR500; 59μg Fe/g) and biofortified (MIB465; 88μg Fe/g) were used. The DOR500 is a common commercial variety, and the MIB465 is a line developed for higher-Fe content. Given the high preva...

We discuss the concept of colimitation of primary productivity in aquatic environments, with an emphasis on reconciling this concept with recent advances in marine bioinorganic chemistry. Colimitations are divided into three categories on the basis of their mathematical formulations and visualizations: type I, independent nutrient colimitation (e.g., N and P); type II, biochemical substitution ...
