Keloids tend to have a genetic component, which means one is more likely to have keloids if one or both of their parents has them. However, no single gene has yet been identified which is a causing factor in keloid scarring but several susceptibility loci have been discovered, most notably in Chromosome 15.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The researchers were surprised to discover that ketolides, which are known to be better antibiotics, allow for many more proteins to be made compared to the older, less efficient macrolides. As a result, it is now believed that allowing cells to make some proteins could be much more damaging for a microbe than not letting it make any proteins ...
In addition to the described above monomeric alkaloids, there are also dimeric, and even trimeric and tetrameric alkaloids formed upon condensation of two, three, and four monomeric alkaloids. Dimeric alkaloids are usually formed from monomers of the same type through the following mechanisms: [ 193 ]
The use of the name probably originated from Captain James Cook's description of one of these shrubs that he used to make an infusion to drink in place of tea. [ 35 ] The commercial tea tree oil industry originated in the 1920s when Australian chemist Arthur Penfold investigated the business potential of a number of native extracted oils; he ...
PAs are compounds made up of a necine base, a double five-membered ring with a nitrogen atom in the middle, and one or two carboxylic esters called necic acids. [17] Four major necine bases are described, with retronecine and its enantiomer Heliotridine being the largest group, and highly toxic.
Cell metabolism is the process by which individual cells process nutrient molecules. Metabolism has two distinct divisions: catabolism, in which the cell breaks down complex molecules to produce energy and reducing power, and anabolism, in which the cell uses energy and reducing power to construct complex molecules and perform other biological ...
Triamcinolone acetonide, sold under the brand name Kenalog among others, is a synthetic corticosteroid medication used topically to treat various skin conditions, [13] to relieve the discomfort of mouth sores, and by injection into joints to treat various joint conditions.
