The importance of cortisol is especially evident when it becomes deficient in a state known as adrenal insufficiency [ 111].
Our division of function hypothesis, with its assumption that the proto-nucleus became deficient in certain life functions before internalization, provides a solution for this difficulty, in that a transition period in which its membrane proteins had reduced functionality would not necessarily be fatal if its symbiotic partners were providing it with proteins, ATP, and other metabolites.
Primary murine fibroblasts became deficient in a G1 checkpoint activated by ionizing radiation (IR) when both wild-type p53 alleles were disrupted.
Total myocardial copper levels became deficient in untreated diabetes but were normalized by TETA-treatment.
While we can synthesize vitamin D from the sun, it's very easy to become deficient in the darker months.
"All plant foods contain amino acids in different proportions and there is plenty of protein in plants to meet all requirements," "As long as you are eating enough calories to sustain yourself and are focusing on whole foods instead of refined foods, it would be impossible to become deficient in protein," adds the nutritionist.

In fact, it was demonstrated that relapses of ovarian carcinomas resistant to cisplatinum treatment concomitantly become deficient in argininosuccinate synthetase, a rate limiting enzyme of arginine biosynthesis, and thus potentially sensitive to arginine-degrading enzymes [ 14].
However, in diseases such as osteoporosis this process becomes deficient and microcracks can accumulate.
"It is perfectly fine to be a vegetarian, but you should take care about what you're eating to ensure you don't become deficient in nutrients such as iron, zinc and B vitamins," says Rohrmann.
The immune response itself may become deficient in human diseases involving white cells, such as multiple myeloma, macroglobulinemia, Hodgkin lymphoma, and chronic lymphocytic leukemia.
