The 80% of bone mineralisation occurs in the third trimester of pregnancy. The daily fetal requirement is 310 mg of calcium and 170 mg of phosphorus [1]. The bone mineral density (BMD) correlates positively with gestational age, weight and length [2]. At birth, extremely premature infants (ELBWI)canpresent hypocalcaemia because of interruption of the maternal calcium supply, high level of calci...
Many publications describe cryopreservation techniques but only a few studies have focused on the biochemical and physiological changes occurring in plants regenerated from seeds exposed to liquid nitrogen. This paper aims at describing the effect of common bean seed cryostorage on mineral nutrition of young plantlets. The following elements were measured on leaves of 10-dayold plantlets from n...
Bone is composed of an organic matrix of type I collagen associated with non-collagenous proteins and a large mineral component consisting of calcium hydroxyapatite. To date, measurement of bone mass only takes into account the mineral component of bone, while recognizing that the organic matrix is important in providing both structure and strength. The present paper will concentrate on the inf...
Mineral nutrient deficiencies constitute major limitations for plant growth on agricultural soils around the world. To identify genes that possibly play roles in plant mineral nutrition, we recently generated a high-density array consisting of 1,280 genes from tomato (Lycopersicon esculentum) roots for expression profiling in nitrogen (N) nutrition. In the current study, we used the same array ...
A green house experiment was conducted to investigate the effect of arbuscular mycorrhiza inoculation on plant growth and uptake of mineral nutrition in Ipomoea aquatica considering the objective of using environmental friendly biofertilizer instead of chemical fertilizer. A common leafy vegetable plant Ipomoea aquatica was grown with mycorrhiza and without mycorrhiza for 42 days. After harvest...
OBJECTIVE To understand the changes of the nutrition labeling of packaged food in China two years after the promulgation of the Regulation for Food Nutrition Labeling, which encourages food manufacturers to identify nutrition labeling. METHODS Investigators copied out the nutrition information panel, nutrition claim and nutrient function claim of packaged food in a supermarket with prepared q...
