Calcium lactate crystals that sometimes form on Cheddar cheese surfaces are a significant expense to manufacturers. Researchers have identified several postmanufacture conditions such as storage temperature and packaging tightness that contribute to crystal formation. Anecdotal reports suggest that physical characteristics at the cheese surface, such as roughness, cracks, and irregularities, ma...

background: milk fever in cattle, sheep and goats occurs  around the time of parturition and is caused by hypocalcemia. objectives: the aim of this study was to investigate the physiological effects of experimental hypocalcemia on electrocardiography, hematology and serum biochemical changes in markhoz goat breed. methods: ethylene diamine tetra- acetate solution 4.6% was intravenously infused ...

1. Rachitic bone lesions may be produced in rats by a diet containing an excess of calcium, but deficient in phosphates. 2. Similar lesions follow a diet deficient in calcium, but containing an excess of phosphates. The endochondral lesions, however, are less pronounced. 3. A diet deficient in both calcium and phosphate induces atypical rickets. 4. Inorganic salts other than calcium or phosphat...

The effects of various forms of acidosis on ionized calcium concentrations were investigated in vivo in rabbits and in vitro in human plasma. Calculation of least square regression equations of ionized calcium (mM) on pH yielded the following regression coefficients in human plasma: bypercapnic acidosis —0.53±0.07; hydrochloric acidosis —0.65 ±0.06; lactic acidosis —0.27±0.05. These findings in...

INTRODUCTION Liver failure patients might be at risk for citrate accumulation during continuous venovenous hemodialysis (CVVHD) with regional citrate anticoagulation. The aim of this study was to investigate the predictive capability of baseline liver function parameters regarding citrate accumulation, expressed as an increase in the calcium total/calcium ionized (Ca(tot)/Ca(ion)) ratio ≥ 2.5, ...

Roux-en-Y gastric bypass (RYGB) surgery leads to bone loss in humans, which may be caused by vitamin D and calcium malabsorption and subsequent secondary hyperparathyroidism. However, because these conditions occur frequently in obese people, it is unclear whether they are the primary causes of bone loss after RYGB. To determine the contribution of calcium and vitamin D malabsorption to bone lo...

AIMS to design calcium and zinc-loaded bioactive and cytocompatible nanoparticles for the treatment of periodontal disease. METHODS PolymP-nActive nanoparticles were zinc or calcium loaded. Biomimetic calcium phosphate precipitation on polymeric particles was assessed after 7 days immersion in simulated body fluid, by scanning electron microscopy attached to an energy dispersive analysis syst...

The purpose of this study was to examine plaque and saliva composition after a fluoride rinse and subsequent sucrose application. Fifteen subjects accumulated plaque for 48 h, and then rinsed with a fluoride rinse based on 228 microg/g (ppm) Na2SiF6 and some received no rinse. After 60 min, upper and lower buccal molar plaque samples and 1-min saliva samples were collected. The subjects then ri...
