Prefix (mathematics)
A prefix is an affix which is placed before the stem of a word. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the word to which it is affixed. Prefixes, like other affixes, can be either inflectional, creating a new form of a word with the same basic meaning and same lexical category, or derivational, creating a new word with a new semantic meaning and sometimes also a different lexical category. Prefixes, like all affixes, are usually bound morphemes. English has no inflectional prefixes, using only suffixes for that purpose. Adding a prefix to the beginning of an English word changes it to a different word. For example, when the prefix ''un-'' is added to the word ''happy'', it creates the word ''unhappy''. The word ''prefix'' is itself made up of the stem ''fix'' (meaning "attach", in this case), and the prefix ''pre-'' (meaning "before"), both of which are derived from Latin roots.

Anti-inflammatory
Anti-inflammatory is the property of a substance or treatment that reduces inflammation, fever or swelling. Anti-inflammatory drugs, also called anti-inflammatories, make up about half of analgesics. These drugs reduce pain by inhibiting mechanisms of inflammation, as opposed to opioids, which affect the central nervous system to block pain. Common anti-inflammatory drugs include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antileukotrienes, and monoclonal antibodies. Drugs Clinically approved Nonsteroidal anti-inflammatory drugs NSAIDs alleviate pain by counteracting the cyclooxygenase (COX) enzyme involved in pain mechanisms. Some common examples of NSAIDs are aspirin, ibuprofen, and naproxen. Selective COX-2 inhibitors, such as celecoxib, block the enzymatic conversion of arachidonic acid into prostaglandin, inhibiting inflammation and pain. Analgesics commonly associated with anti-inflammatory drugs, such as acetaminophen (paracetamol), hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allotransplantation
Allotransplant (''allo-'' meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and xenotransplantation (from other species). Allografts can be referred to as "homostatic" if they are biologically inert when transplanted, such as bone and cartilage.(W. P. Longmire, ''J. National Cancer Institute'' 14, 669: ''The term ''homostatic graft'' might be applied to inert tissues such as bone and cartilage when transferred from one individual to another of the same species; and the term ''homovital graft'' might be used in reference to grafts whose ...
