Active transport of calcium by intestine: effects of dietary calcium
American Journal of Physiology-Legacy Content, 1961The small intestine of the rat responds facultatively to a diet low in Ca by increasing the active transport of the cation. The effects of calcium deprivation were studied with everted gut sacs and with duodenal slices in vitro, and the experiments demonstrate that following this stimulus almost the entire small intestine of a young rat can transfer ...

Dietary Calcium Perturbation in Patients with Abnormal Calcium Deposition
The Journal of Clinical Endocrinology & Metabolism, 1970ABSTRACT The response to dietary calcium perturbation was studied in 3 individuals with pathologic calcium deposition. In all 3 subjects, base-line kinetic studies on normal dietary calcium intake revealed an increased bone accretion rate, increased bone resorption rate and decreased renal excretion rate as compared to normal subjects on a similar ...

Dietary Calcium and Osteoprotegerin
2015Calcium is an essential trace element of human body. It is both the constructor and regulator of the body, and the source of our human life. Osteoprotegerin (OPG) is a glycoprotein involved in bone metabolism and plays a regulatory role in the immune, the skeletal and the circulatory systems.

Dietary calcium, calcium supplements, and the risk of calcium oxalate kidney stones
American Journal of Health-System Pharmacy, 2006Kidney stones are concentrated masses of crystallized substances, such as calcium, oxalate, or uric acid, that are excreted by the kidneys into the urine. The formation of calcium oxalate stones depends on the level of urinary supersaturation with calcium and oxalate.

Dietary Requirements for Calcium
1988Normal, healthy adults must be assumed to be in a state of nutritional equilibrium — at least over a period of time. They must be taking in nitrogen, phosphorus, sodium and other elements at the same rate as they are excreting them. For some of these elements, the calculation of a body balance is very difficult, but in the case of calcium it is ...

Dietary Calcium and Metacarpal Growth in Ewes
The Journal of Nutrition, 1988The effects of excess dietary calcium on bone growth were quantified in 44 ewes fed ad libitum diets that contained one of four levels of dietary calcium (0.37, 0.56, 1.13 and 1.80%) and 0.42% phosphorus. Animals were slaughtered at one of six ages, circulating concentrations of hormones and minerals were measured and bone morphometry was evaluated ...

Dietary Protein Increases Urinary Calcium
The Journal of Nutrition, 1990A partir de donnees disponibles dans la litterature, on etudie l'influence de la teneur en proteines, calcium et phosphore dans l'alimentation sur l'equilibre calcique chez l'individu adulte. Relations entre les apports en calcium et proteine par l'alimentation ainsi qu'entre proteine et phosphore sur la retention en ...

The Effects of Dietary Calcium on Hypertension
2015The role of Ca in the prevention of hypertension is controversial, with some research showing a lowering of blood pressure due to Ca supplementation and other studies that were not able to detect any ipotensive effect of this mineral. According to recent and less recent studies, Ca can lower blood pressure in two ways: (1) by increasing the endothelial

The incidence of obesity in the United States is reaching epidemic proportions, and it is estimated that 97 million adults are overweight or obese (1). Obesity substantially increases morbidity from a variety of diseases, including hypertension, dyslipidemia, type 2 diabetes, and stroke.
