Calcium and Phosphate Homeostasis

The normal concentration of calcium and phosphate in blood and extracellular fluid is near the saturation point elevations can lead to diffuse precipitation of calcium phosphate in tissues leading to widespread organ dysfunction and damage Preventing hypercalcemia and hypocalcemia is largely the result of robust endocrine control systems

Neonatal Parenteral and Enteral Nutrition

You will need to consider the percent of enteral fluids or feeds and the percent of TPN For example a 1 0 kg baby on 100 ml/kg/day of TPN and 25 ml/kg/day of feeds is receiving about TPN and enteral nutrition (EN) The TPN should reflect this proportion Protein lipids and electrolytes should equal about of the total nutritional

Calcium phosphate co‑precipitation

Calcium phosphate facilitates the binding of the condensed DNA in the co-precipitate to the cell surface and the DNA enters the cell by endocytosis Aeration of the phosphate buffer while adding the DNA-calcium chloride solution helps to ensure that the precipitate that forms is as fine as possible which is important because clumped DNA will
