The mechanism of calcium ...

Amorphous Calcium Phosphate (ACP) is an essential mineral phase formed in mineralized tissues and the first commercial product as artificial hydroxyapatite. ACP is unique among all forms of calcium phosphates in that it lacks long-range, periodic atomic scale order of crystalline calcium phosphates. The X-ray diffraction pattern is broad and diffuse with a maximum at 25 degree 2 theta, and no o...

The stimulation of the formation of inositol phosphates by various cholinergic agonists and antagonists was studied in rat brain cortical slices. Incubation of the slices with [3H]inositol led to the incorporation of radioactivity into inositol lipids. The accumulation of inositol phosphates was then followed in the presence of 8 mM lithium which blocks the hydrolysis of inositol phosphate. The...

In order to improve soil quality, size, and appearance of plants, various types fertilizers are used in Poland. They rich nitrogen, phosphorus, calcium, potassium. Plants fertilized before sowing, during germination, crop growth. Such agricultural activity can have a negative effect on the chemical composition atmospheric aerosols, which be transported with air masses far away from sources regi...

The elemental and chlorine isotope compositions of calcium-phosphate minerals are key recorders the volatile inventory Mars, as well planet’s endogenous magmatic hydrothermal history. Most martian meteorites have clear evidence for exogenous impact-generated deformation metamorphism, yet effects these shock metamorphic processes on isotopic records contained within calcium phosphates not been e...

BACKGROUND Bioinorganics have been explored as additives to ceramic bone graft substitutes with the aim to improve their performance in repair and regeneration of large bone defects. Silicon (Si), an essential trace element involved in the processes related to bone formation and remodeling, was shown not only to enhance osteoblasts proliferation but also to stimulate the differentiation of mese...

Materials based on Mg2+-containing phosphates are gaining great relevance in the field of bone tissue repair via regenerative medicine methods. Magnesium ions, together with condensed phosphate play substantial roles process remodeling, affecting early stage regeneration through active participation osteosynthesis. In this paper we provide a comprehensive overview usage biomaterials magnesium a...

Acidification is an important process in the production of several dairy products and has impact taste, viscosity, shelf life products. This paper deals with development empirical mathematical model to describe milk acidification terms pH dynamics. The built upon experiments pasteurized skimmed for acid-induced casein precipitation extended predict partitioning calcium phosphates whey dynamics ...

Experimental data were collected on the solubility equilibrium of the mineral of bone, tooth enamel and calcium phosphate renal stones. Evaluation in the form of potential diagrams of Ca(OH)2 versus H3PO4 shows that Ca/P ratios of 1, 4/3, 10/7, 3/2 and 5/3, related to phases like brushite, octocalcium phosphate, whitlockite, defective apatite and hydroxyapatite respectively can be important.
