Due to the properties of tumor cell, the tumor establishes itself in the organ and grows there, so there is a competition between the tumor cells and host cell (normal cells) for nutrients. Evidences show that high dietary phosphorus increases the rate of protein synthesis and thus the cell number. So, other than oxygen, sulfur, the important element that both tumor cells and normal cells need ...

backgroundrickets is a disorder due to impaired metabolism of bone mineralization which caused by low concentrations of extra-cellular calcium or phosphate. in children, hypophosphatemic rickets (hr) happen malabsorption of phosphate and increasing of renal tubular loss.case presentation we present the case of a 4-year-old girl who had medical history of hr with failure to thrive (ftt). child h...

objective(s) matrix metalloproteinases comprise a family of enzyme that is able to degrade components of extra cellular matrix. there are single nucleotide polymorphisms in the promoter regions of several genes with ability to influence cancer susceptibility. the aim of this study was to analyses association between mmp2 and mmp9 promoter polymorphisms and head and neck squamous cell carcinoma ...

traumatic brain injury (tbi) results from a sudden and external physical impact to the head, and often leads to motor and cognitive impairment. using tissue engineering strategies, we aimed to review aspects of extra cellular matrix (ecm) based scaffold that could be delivered to the injured brain. the ecm is produced intracellularly and secreted to form a dense network of proteins and glycans,...

One possibility to measure the extra-phosphoric effect of exogenous phytase is to use a higher concentration of this enzyme in the diets not limiting in phosphorus, to be sure that any observed effect is not caused by an increase in phosphorus digestibility. However, it is important to know how the requirements of the bird relate to the phosphorus content of the basal diet, because when the bas...

Phosphorus plays a critical role in cellular biology (5). Many cellular processes require phosphorus in one form or another and include nucleic acid synthesis and metabolism (37), energy metabolism (42, 46), cellular signaling (38), membrane integrity (53, 58), muscle function (10, 33), enzyme activity (74), lipid metabolism (25), and bone mineralization (30). Phosphorus is present in virtually...

there is a new technique to measure total body water named bio-electrical impedance analysis (bia), used in healthy subjects and patients. bia determines the total body water (tbw), fat-free mass (ffm), body cell mass (bcm), extra cellular water (ecw), and intra cellular water (icw) in subjects without significant fluid and electrolyte imbalance. there are several methods such as segmental bia,...
