The effects of boron supplementation on bone mineral density, blood and urinary calcium, magnesium, phosphorous and urinary boron in female athletes
The effects of boron supplementation on blood and urinary minerals were studied in 17 female college athletes and 11 sedentary college control subjects. The subjects were similar in age (19.8 ± 1.4 and 20.3 ± 1.1 years for athletes and sedentary groups, respectively) and weight (61.8 ± 9.1 and 59.6 …

Protein-associated calciuria in a free living population
… day dietary record and collected their total urinary output for the last three days of the five. Urinary calcium, magnesium, sulfate and nitrogen were determined on these samples. There was a significant correlation of r = .31 (p < .0001) between dietary protein and urinary calcium. Linear …

Investigation of the effect of hydroxycitric acid on urinary calcium oxalate risk factors for kidney stone formation in artificial urine: theoretical modelling and in vitro crystallisation experiments
… stones are composed of different mineral types. Calcium Oxalate is the most common kind of stone. The principal aim of this research was to establish whether hydroxycitrate (HCA) affects and/or inhibits calcium oxalate crystallisation. A three-pronged approach was adopted, involving the …

Investigation of the effect of a solution of lime powder on urinary calcium oxalate kidney stone risk factors in artificial and real urines : in vitro and in vivo studies
… appear to affect the ability of urine to inhibit calcium oxalate crystallization. In South Africa, previous studies have demonstrated that black and white individuals respond differently to lithogenic and antilithogenic dietary supplements. OBJECTIVES: The current project was undertaken to study …

ΜΕΤΑΒΟΛΙΣΜΟΣ ΤΟΥ ΑΣΒΕΣΤΙΟΥ ΚΑΙ ΟΣΤΕΟΠΑΘΕΙΑ ΣΕ ΧΡΟΝΙΟΥΣ ΑΛΚΟΟΛΙΚΟΥΣ
… HEPATITIS OR CIRRHOSIS. LOW DIETARY CALCIUM ANDHIGH URINARY CALCIUM EXCRETION, CORRELATED WITH OSTEOPENIA AND BONE DEMINERALIZATION, SUGGESTING BOTH FACTORS CONTRIBUTE TO THE BONE DISEASE OBSERVED IN ALCOHOLIC POPULATIONS. PLASMA 25-OH-D3 CONCENTRATIONS WERE LOW BUT DID NOT CORRELATE …

Dose-Dependent Effects of Salmon Calcitonin on Bone Turnover in Ovariectomized Rats.
… were noted between groups for levels of urinary helical peptides or serum pyridinoline [ELISA], indicators of bone resorption. Urinary calcium excretion [capillary ion electrophoresis] was significantly higher in subjects receiving 50 IU/kg of calcitonin than other ovariectomized subjects …

The Effect of Long Term High Protein Induced Calciuria on Calcium Metabolism and Bone Status in Adult Rats
… of osteoporosis. The source of increased urinary calcium is controversial and has been attributed to either increased absorption, increased bone resorption or both. A 20 week study was conducted to determine long-term effects of various protein sources on calcium metabolism and bone status …

Effect of dietary calcium and phosphorus levels on magnesium utilization in sheep
… to study the effects of feeding two levels of calcium and phosphorus alone and in combination, on magnesium utilization in ruminants. Twelve wether lambs were used in two metabolism trials. The two levels of calcium were 0.4 and 1.4% and the two levels of phosphorus were 0.3 and 1.3%. Apparent …

Evaluating the inclusion of alfalfa hay in diets fed to pregnant and non-lactating Holstein cows during the prepartum period
… or alfalfa hay (AH) with the inclusion of either calcium chloride (CL) or polyhalite mineral (PO). Eighty Holstein cows in their 2nd parity or greater were fed an experimental diet according to a 2 2 factorial arrangement of treatments during the prepartum period (21 d before calving). All diets …

Cadmium, kidney and bone
… study, the relationships between kidney cadmium, urinary calcium and bone mineral density were investigated. A positive association was found between kidney cadmium and calcium excretion in women, but not in men. Negative correlations were found between kidney cadmium and bone mineral density, but …

Effect of a Low-Carbohydrate, High-Protein Diet on Bone Mineral Density, Biomarkers of Bone Turnover, and Calcium Metabolism in Healthy Pre-Menopausal Females
… bone turnover, indicators of acid-base balance, calcium homeostasis and fasting lipids in healthy pre-menopausal women was conducted. Women, aged 32 - 45 y, with a body mass index between 25-41 kg/m2 were randomized into one of two diet groups: LCHP (n = 13) or high-carbohydrate, low-fat (HCLF) …

Investigation of the potential beneficial effects of supplemental polyunsaturated fatty acids and glycosaminoglycans on the risk factors for calcium oxalate kidney stone formation using theoretical, experimental and human models
Introduction: Two hypotheses with regard to calcium oxalate (CaOx) renal stone formation were tested in this thesis. The first hypothesis is that fatty acid (FA) supplementation (n-6 and n-3) and chondroitin sulphate (CS) supplementation may reduce the plasma (FA) and urinary (FA and CS) risk …

Dietary protein and bone health: Harmonizing conflicting theories
… of research. Protein unambiguously increases urinary calcium losses, which is completely attributable to the dietary acid load imposed by metabolism of sulfur containing amino acids into acid equivalents. Although alternate dietary sources of fixed acid cause demineralization of bone and …

The effect of Ascorbic acid ingestion on the risk of calcium oxalate kidney stone formation
… ingestion of ascorbic acid on the risk of calcium oxalate kidney stone formation. Ten healthy male subjects (ages 20 to 30 years) participated in the study. Each was required to ingest a daily dose of 4 g ascorbic acid per day for a period of 5 days. Twenty-four hour urines were collected …
