If chewing gum is exposed to moisture, over time water migration may occur, making the gum soggy. In lollipops with a gum center, water migration can lead to the end of the product's shelf life, as it causes the exterior hard candy shell to soften and the interior gum center to harden.
Vesalius noted many structural characteristics of both the brain and general nervous system during his dissections. [12] In addition to recording many anatomical features such as the putamen and corpus callosum , Vesalius proposed that the brain was made up of seven pairs of 'brain nerves', each with a specialized function.
Healthy gums fill and fit each space between the teeth, unlike the swollen gum papilla seen in gingivitis or the empty interdental embrasure seen in periodontal disease. Healthy gums hold tight to each tooth in that the gum surface narrows to "knife-edge" thin at the free gingival margin. On the other hand, inflamed gums have a "puffy" or ...
[5] [6] it was an early example of a functional gum – chewing gum as a drug delivery system. It was significant in the recognition of aspirin's antithrombotic effect, when general practitioner Lawrence Craven reported in 1953 that patients who chewed Aspergum as an analgesic after tonsillectomy tended to bleed more easily.
Research during this time was focused on the search for a painkiller that did not have the addictive character or overdose risk of morphine. [11] [12] Rabi Simantov and Solomon H. Snyder isolated morphine-like peptides from calf brain. [13] Eric J. Simon, who independently discovered opioid receptors, later termed these peptides as endorphins. [14]
There were more than 492,000 traumatic brain injuries, mostly mild concussions, in the military between 2000 and 2023, the most recent year with available data, Defense Department statistics show.

Cementum is a specialized bone like substance covering the root of a tooth. [15] It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Cementum is excreted by cementoblasts within the root of the tooth and is thickest at the root apex. Its coloration is yellowish and it is ...
