Regeneration of the body
Is there a method to stimulate collagene proliferation in the body? 2A02:908:424:9D60:1D3E:5FB6:8A8A:44A6 (talk) 18:22, 16 December 2022 (UTC)
 * Not sure, but this article may give you some leads for your research. -- Jayron 32 18:39, 16 December 2022 (UTC)
 * Collagen is a collective noun for a large class of proteins with very different characteristics, from the smooth and elastic cartilage found in joints to the tough ossein in the bone matrix. If collagen production is stimulated artificially, it should be of just the right type in just the right place by just the right amount; of the many disorders associated with collagen, a large number is caused by overproduction. In cases caused by a genetic disorder, gene therapy may offer a spot of light on the horizon. Severe nutritional deficiency can contribute to low collagen production, but will then generally also result in many other problems. For otherwise healthy individuals, a balanced diet does more to stimulate healthy collagen production than available collagen supplements. This article on WebMD contains some nutritional suggestions. --Lambiam 09:17, 17 December 2022 (UTC)

Definition of dead
Why is circulatory determination of death abbreviated as DCDD rather than CDD? &mdash; Python Drink (talk) 22:16, 16 December 2022 (UTC)
 * I've only seen DCDD used in the context of death-determination for purposes of organ donation, with phrases like "donation after circulatory determination of death". So the first "D" seems like "donation". DMacks (talk) 22:21, 16 December 2022 (UTC)
 * Indeed; see this. Alansplodge (talk) 12:37, 17 December 2022 (UTC)
