| post-transcriptional processing | The enzymatic processing of the primary RNA transcript, which producesmessenger RNA and transfer RNA. (09 Oct 1997) |
|---|---|
| post-translational modification | The enzymatic processing of a polypeptide chain after translation from messenger RNA and after peptide bond formation has occurred. Examples include glycosylation, acylation, limited proteolysis, phosphorylation, isoprenylation. (10 Oct 1997) |
| post-tympanic | <anatomy> Situated behind the tympanum, or in the skull, behind the auditory meatus. Origin: Pref. Post- + tympanic. Source: Websters Dictionary (01 Mar 1998) |
| heart rupture, post-infarction | Rupture of the heart after myocardial infarction. (12 Dec 1998) |
| protein processing, post-translational | Any of various enzymically catalyzed post-translational modifications of peptides or proteins in the cell of origin. These modifications include carboxylation, hydroxylation, acetylation, phosphorylation, methylation, glycosylation, oxidation-reduction, degradation and lysis, peptide bond formation, and changes in molecular weight and electrophoretic motility.

| bag-gel implant | An implant composed of a silicone rubber bag containing a silicone gel; used in augmentation mammaplasty. (05 Mar 2000) |
| breast implant | <procedure, surgery> A sac inserted under the skin of the chest wall to restore or improve the shape of the breast. (16 Dec 1997) |
| magnetic implant | A tissue-tolerated, magnetised metal placed within the bone to aid in denture retention; a similar magnet is placed in the overlying denture to complete the field. (05 Mar 2000) |
| penile implant | A rigid, flexible, or inflatable device surgically placed in the corpora cavernosa to produce an erection. (05 Mar 2000) |
| cochlear implant | An electronic device implanted under the skin with electrodes in the middle ear on the promontory or cochlear window or in the inner ear in the cochlea to create sound sensation in total sensory deafness. A microphone behind the ear feeds sound waves into a microprocessor carried on the body, which analyzes the data and sends information back to a radio transmitter that triggers the electrodes in the middle or inner ear to produce the appropriate electrical pulses. This does not enable the patient actually to hear, but rather to distinguish different sounds according to the neural sensation they produce. The first successful cochlear implant was performed in 1978 in Melbourne, Australia. Such devices are among many implanted aids which have been made possible by the advent of microchip technology. Synonym: cochlear prosthesis. (05 Mar 2000) |
| pin implant | A type of implant usually rod-shaped, used in the area of the maxillary sinuses. (05 Mar 2000) |
| silicone implant | Implant composed of silicone; common form of breast implant for augmentation. (05 Mar 2000) |
| submucosal implant | An implant resting beneath the mucosa. See: implant denture. (05 Mar 2000) |
| subperiosteal implant | An artificial metal appliance made to conform to the shape of a bone and placed on its surface beneath the periosteum. See: implant denture substructure. (05 Mar 2000) |
| supraperiosteal implant | An alloplastic graft inserted superficial to the periosteum to change the contour of an area. (05 Mar 2000) |
