Scarless wound healing is a concept based on the healing or repair of the skin (or other tissue/organs) after injury with the aim of healing with subjectively and relatively less scar tissue than normally expected. Scarless healing is sometimes mixed up with the concept of scar free healing, which is wound healing which results in absolutely no ...
Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase. [26] Thus the use of estrogen is a future possibility for treating chronic wounds.
Removal of the salivary glands of mice [35] and rats slows wound healing, and communal licking of wounds among rodents accelerates wound healing. [36] [37] Communal licking is common in several primate species. In macaques, hair surrounding a wound and any dirt is removed, and the wound is licked, healing without infection. [38]
Disfigurement is the state of having one's appearance deeply and persistently harmed medically, such as from a disease, birth defect, or wound. General societal attitudes towards disfigurement have varied greatly across cultures and over time, with cultures possessing strong social stigma against it often causing psychological distress to ...
Irwin Stone (1907–1984) was an American biochemist, chemical engineer, and writer.He was the first to use ascorbic acid in the food processing industry as a preservative, and originated and published the hypothesis that humans require much larger amounts of Vitamin C for optimal health than is necessary to prevent scurvy.
Cardiovascular diseases are the leading cause of death worldwide, and have increased proportionally from 25.8% of global deaths in 1990, to 31.5% of deaths in 2013. [44] This is true in all areas of the world except Africa. [44] [45] In addition, during a typical myocardial infarction or heart attack, an estimated one billion cardiac cells are ...
Primary pathogens cause disease as a result of their presence or activity within the normal, healthy host, and their intrinsic virulence (the severity of the disease they cause) is, in part, a necessary consequence of their need to reproduce and spread. Many of the most common primary pathogens of humans only infect humans, however, many ...
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
