Calcium Deficiency in Diet Decreases the Magnesium Content in Bone and Affects Femur Physicochemical Properties in Growing Rats.

This study evaluates the effect of three calcium levels in the diet (normal, moderate, and severe calcium depletion) on bone metabolism of male Wistar rats during their growth period. Bone mineral density (BMD) and femur length were determined in vivo during the growth stage using a single X-ray transmission system. The apparent calcium absorption was calculated in the rat adolescent and adulthood stages.

Effect of the addition of potassium and magnesium ions on the thermal, pasting, and functional properties of plantain starch (Musa paradisiaca).

Starch is a biopolymer widely used in the industry; however, rarely used in its native form, making necessary its modification. This work studied the effect of the inclusion of potassium and magnesium ions on the physicochemical properties of plantain starch. Ionic solutions were prepared at five concentrations between 0.
