An acidic intravenous source of phosphorus (Addiphos) was compared with dipotassium hydrogen phosphate in 25 preterm infants to study acid-base state. Eight infants were given either Addiphos or dipotassium hydrogen phosphate alternately for 48 hour periods and similar amounts of calcium and phosphorus were delivered. There were no significant differences in calcium and phosphorus intake, calci...

This research was performed to evaluate the utility of several serum and urine parameters as well as bone ash and plasma parathormone assay to diagnose and monitor diet-related osteopenia in growing pigs. Five diets were tested as follows: calcium-deficient, phosphorus-replete; moderate-deficiency of calcium and phosphorus; marked deficiency of calcium and phosphorus; calcium replete, phosphoru...

BACKGROUND Adequate folate supplementation in the periconceptional phase is recommended to reduce the risk of neural tube defects. Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to su...

UNLABELLED Insufficient calcium intake has been proposed to cause unbalanced energy partitioning leading to obesity. However, weight loss interventions including dietary calcium or dairy product consumption have not reported changes in lipid metabolism measured by the plasma lipidome. METHODS The objective of this study was to determine the relationships between dairy product or supplemental ...

1. 47Ca kinetic studies were performed in eight normal young adult males. Plasma, urinary and faecal stable and radioactive calcium and whole-body radioactivity were measured for up to 40 days after intravenous administration of the tracer. 2. The plasma radioactivity data could be fitted to the sum of four exponentials corresponding to a four-compartment model, but this model did not account f...

A small quantity of extracellular calcium is required for the stimulation of lymphocytes by mitogens such as plant lectins. Lectin binding to the lymphocyte surface and early postbinding events that eventually lead to DNA synthesis are calcium dependent. Mitogenic lectins such as PHA and Con-A rapidly increase the size of an exchangeable pool of cell calcium and cause a smaller rise in intracel...

BACKGROUND African Americans (AAs) have lower circulating 25-hydroxyvitamin D3 [25(OH)D3] concentrations and higher prostate cancer (CaP) aggressiveness than other racial/ethnic groups. The purpose of the current study was to examine the relationship between plasma 25(OH)D3, African ancestry and CaP aggressiveness among AAs and European Americans (EAs). METHODS Plasma 25(OH)D3 was measured us...

Synexin (annexin VII) is a member of the annexin family of calcium and phospholipid binding proteins that promote calcium-dependent aggregation and fusion of lipid vesicles or secretory granules. We have previously suggested that synexin may be involved in membrane fusion processes during exocytosis of lung surfactant since it promotes fusion in vitro of lamellar bodies with plasma membranes. I...
