| eye, artificial | A ready-made or custom-made prosthesis of glass or plastic shaped and coloured to resemble the anterior portion of a normal eye and inserted for cosmetic reasons in the socket of an enucleated or eviscerated eye. (12 Dec 1998) |
| yeast artificial chromosome | <molecular biology> A vector system that allows extremely large segments of DNA to be cloned. Useful in chromosome mapping, contiguous yeast artificial chromosomes covering the whole Drosophila genome and certain human chromosomes are available. Acronym: YAC (15 Nov 1997) |
| yeast artificial chromosomes | Yeast DNA sequences that have incorporated into them very large foreign DNA fragments; the recombinant DNA is then introduced into the yeast by transformation; the use of yeast artificial chromosomes permits the cloning of large genes with their flanking regulatory sequences. (05 Mar 2000) |
| kidney, artificial | Device(s) which can substitute for normally functioning kidneys in cleansing the blood. (12 Dec 1998) |
| urinary sphincter, artificial | An artifical implanted device, usually in the form of an inflatable silicone cuff, inserted in or around the bladder neck in the surgical treatment of urinary incontinence caused by sphincter weakness. Often it is placed around the bulbous urethra in adult males. The artificial urinary sphincter is considered an alternative to urinary diversion. (12 Dec 1998) |
| larynx, artificial | A device, activated electronically or by expired pulmonary air, which simulates laryngeal activity and enables a laryngectomised person to speak. Examples of the pneumatic mechanical device are the tokyo and van hunen artificial larynges. Electronic devices include the western electric electrolarynx, tait oral vibrator, cooper-rand electrolarynx and the ticchioni pipe. (12 Dec 1998) |
| liver, artificial | Devices for simulating the activities of the liver. They often consist of a hybrid between both biological and artificial materials. (12 Dec 1998) |
| agonal infection | An acute infection, commonly pneumonic or septic, occurring toward the end of any disease and often the cause of death. Synonym: agonal infection. (05 Mar 2000) |
| airborne infection | A mechanism of transmission of an infectious agent by particles, dust, or droplet nuclei suspended in the air. (05 Mar 2000) |
| apical infection | Implantation of microorganisms at the apex of a tooth, usually the result of the migration of microorganisms from the pulp canal through the apical foramen. (05 Mar 2000) |
| arbovirus infection | <virology> A type of viral infection that is transmitted by mosquitoes in late spring to early autumn. One manifestation is encephalitis (central nervous system infection). (27 Sep 1997) |
| ascariasis infection | <microbiology> Infection by the nematode Ascaris lumbricoides and is characterised by an early pulmonary phase related to larval migration and a later, prolonged intestinal phase. Adult worms are 15-40 cm in length and maintain themselves in the lumen of the small intestine. Infection occurs after ingesting eggs contained in contaminated food or more commonly, by transmission to the mouth by the hands after contact with contaminated soil. Treatment is with mebendazole or pyrantel pamoate. (27 Sep 1997) |
| atypical mycobacterial infection | <microbiology> Infection with organisms from the Mycobacterium genus other than tuberculosis. Risk factors include immunocompromised patients and those with AIDS. Mycobacterium avium intracellulare is an example which frequently infects AIDS patients. Atypical mycobacterial infections can cause abscesses, septic arthritis and osteomyelitis. Treatment can be difficult due to the emergence of resistance to standard antitubercular antibiotics. (27 Sep 1997) |
| bacterial infection | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
