A previously described mathematical model of Zn absorption as a function of total daily dietary Zn and phytate was fitted to data from studies in which dietary Ca, Fe and protein were also measured. An analysis of regression residuals indicated statistically significant positive relationships between the residuals and Ca, Fe and protein, suggesting that the presence of any of these dietary comp...

ABSTRACT: Using agricultural waste is one of the best ways to reduce the costs and the environmental pollution. Button mushroom´s stipe is a cheap by-product that is rich in nutrients for human nutrition. The purpose of this study is to compare the nutritional value of cap and stipe of button mushroom (Agaricus bisporus). The caps were separated from the stipes after harvesting and parameters s...

In the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. The effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. The results show that the effect of nanoparticles on composite ...

1. Though the occurrence of intestinal mucosal uptake of intact peptides, with cellular hydrolysis to amino acids, has been established, the importance of this mode of absorption in protein absorption is not known. This paper describes a comparison of the rates of intestinal absorption of pancreatic hydrolysates of four proteins with . those of the corresponding acid hydrolysates or amino acid ...

Renal damage due to an accumulation of the metal is an important factor in chronic cadmium poisoning. Absorbed cadmium from the intestine contributes to the accumulation of cadmium in the kidney of normal individuals who are free from other occupational exposures to the metal. Thus, information about intestinal cadmium absorption is important for our understanding of chronic cadmium poisoning. ...

The influence of different protein sources on Zn absorption was evaluated in healthy adults by radioisotopic labelling of single meals, followed by whole-body retention measurements 14 d after intake. Semi-synthetic liquid diets were used for the evaluation of different animal-protein sources and dephytinized soyabean-protein isolate (< 0.01 g phytic acid/kg). Zn absorption was measured in the ...

The digestive cycle following reabsorption of hemoglobin by cells of the proximal convoluted tubules in mouse kidney and the uptake of ferritin by glomerular mesangial cells in the kidney of normal and nephrotic rats were investigated by electron microscopical histochemical procedures. Mouse kidneys, sampled at closely spaced time points between 1 to 48 hours after intraperitoneal injection of ...
