Carcinogenesis. 1999 Mar;20(3):493-7. Promotion of intestinal carcinogenesis by dietary methionine. Duranton B, Freund JN, Galluser M, Schleiffer R, Gossé F, Bergmann C, Hasselmann M, Raul F. The metabolism of the polyamines spermidine and spermine is known to be enhanced in rapidly proliferating cells. Methionine is a precursor of the aminopropyl moieties of these amines. Therefore, [...]
The thyroid hormones associate with three types of simple proteins in the serum: Transthyretin (prealbumin), thyroid binding globulin, and albumin. -Ray Peat, PhD Transthyretin, which carries both vitamin A and thyroid hormones, is sharply decreased by stress, and should probably be regularly measured as part of the thyroid examination. -Ray Peat, PhD Clin Chem Lab [...]
Energy production and resting body temperature regulate many functions. Ample energy is required to relax fully and sleep deeply. The key to quality sleep is high energy metabolism and maintaining optimal body temperature (98-98.6F). Children sleep well because of their ability to maintain a high body temperature and produce energy and carbon dioxide. The combination [...]
The altitude itself helps the thyroid to function normally. For example, one study (Savourey, et al., 1998) showed an 18% increase in T3 at a high altitude, and mitochondria become more numerous and are more efficient at preventing lactic acid production, capillary leakiness, etc. -Ray Peat, PhD Eur J Appl Physiol Occup Physiol. 1998;77(1-2):37-43. Pre-adaptation, [...]
Adrenaline decreases the conversion to T4 to T3, and increases the formation of the antagonistic reverse T3 (Nauman, et al., 1980, 1984). -Ray Peat, PhD Eur J Clin Invest. 1980 Jun;10(3):189-92. In vivo and in vitro effects of adrenaline on conversion of thyroxine to triiodothyronine and to reverse-triiodothyronine in dog liver and heart. Nauman A, [...]

PHYS ED | By GRETCHEN REYNOLDS June 6, 2012, 12:01 AM Source For people who exercise but fret that they really should be working out more, new studies may be soothing. The amount of exercise needed to improve health and longevity, this new science shows, is modest, and more is not necessarily better. That is the message of [...]
Also see: Glucocorticoids, Cytochrome Oxidase, and Metabolism Fat Deficient Animals – Activity of Cytochrome Oxidase Cytochrome oxidase is one of the enzymes damaged by stress and by blue light, and activated or restored by red light, thyroid, and progesterone. It’s a copper enzyme, so it’s likely to be damaged by excess iron. It is most [...]
