It is speculated that the propolis production involves partial digestion or mixing with saliva of the materials gathered from plant bark, buds and flowers4, however, there is no positive evidence of such chemical changes1. Bees colonies that produce substantial quantities of propolis have been ...
They studied the compound's chemical structure. It is applied in a cream and can protect the skin from the sun and heal chemical burns, according to the team. Laura Baisas, Popular Science, 2 Nov. 2023 In the United States, the act of euthanasia is always by chemical means at the ...
elicitation,evocation,induction- stimulation that calls up (draws forth) a particular class of behaviors; "the elicitation of his testimony was not easy" kick- the sudden stimulation provided by strong drink (or certain drugs); "a sidecar is a smooth drink but it has a powerful kick" ...
A reconsideration of literature data reveals that the incorporation of vacancies, Na, K, Sr, Cl, and CO 3 into hydroxyapatite increases its apparent solubility product, whereas that of F decreases it. It is further shown that the composition of saliva is regulated so that a steady state is ...
compound, in chemistry, a substance composed of atoms of two or more elements in chemical combination, occurring in a fixed, definite proportion and arranged in a fixed, definite structure. A compound is often represented by its chemical formula. The formula for water is H2O, and for sodium ...
saliva, food, and beverages. Intermittent exposure occurs during eating or drinking until teeth are cleaned. Continuous exposure may, however, occur as chemical agents can be absorbed by adherent debris (such as calculus or food particles) at the margin of restorations or be produced by bacterial...
Since the structure of PNIPAM is a three-dimensional network, the problem of pre-release of loaded chemicals leaking from the network structure is unavoidable. To address this problem, You et al. prepared a controlled release carrier with a gated structure by grafting PNIPAM onto the surface of...
those found in tears and saliva (e.g., lysozyme, lactoferrin, lactoperoxidase). Secretions in the trachea and lungs also contain lysozyme and lactoferrin, as well as a diverse group of additional chemical mediators, such as the lipoprotein complex calledsurfactant, which has antibacterial properties...

miosis, mydriasis, increased salivation, lacrimation, piloerection, and urination. Such acute clinical signs were not considered of relevance for mixture risk assessment of chronic exposure in Nielsen et al. (2012) and also not in the current project. A CAG at level 2 “Functional alteration ...
