Central pontine myelinolysis scenario the CPM is caused by polydipsia leading to low blood sodium levels (hyponatremia). In schizophrenic patients with psychogenic polydipsia, inadequate thirst reception leads to excessive water intake, severely diluting serum sodium. With this excessive thirst combined with psychotic symptoms, brain damage such as CPM may result from hyperosmolarity caused by excess intake of fluids, (primary polydipsia) although this is difficult to determine because such patients are often institutionalised and have a long history of mental health conditions. It has been observed following hematopoietic stem cell transplantation. CPM may also occur in patients prone to hyponatraemia affected by: The currently
Fetal bovine serum which they can survive, grow, and divide. FBS is not a fully defined media component, and as such may vary in composition between batches. As a result, serum free and chemically defined media (CDM) have been developed as a matter of good laboratory practice. Fetal bovine serum is a by-product of the dairy industry. Fetal bovine serum, as with the vast majority of animal serum used in cell culture, is produced from blood collected at commercial slaughterhouses from dairy cattle that also supply meat intended for human consumption. The first stage of the production process for fetal bovine serum is
