| fluorescence recovery after photobleaching | Many fluorochromes are bleached by exposure to exciting light. If, for example: the cell surface is labelled with a fluorescent probe and an area bleached by laser illumination, then the bleached patch that starts off as a dark area will gradually recover fluorescence. The recovery is due to the re population of the area by unbleached molecules and diffusion of bleached molecules to other areas. The rate and extent of recovery are a measure of the fluidity of the membrane and the proportion of labelled molecules that are free to exchange with adjacent areas. The technique is usually applied to cell surface fluidity or viscosity measurements, but is also applicable to other structures. (18 Nov 1997) |

| adenovirus early proteins | <molecular biology, protein, virology> Proteins encoded by adenoviruses that are synthesised prior to, and in the absence of, viral DNA replication. The proteins are involved in both positive and negative regulation of expression in viral and cellular genes, and also affect the stability of viral mRNA. Some are also involved in oncogenic transformation. (12 Dec 1998) |
| genes, immediate-early | Genes that show rapid and transient expression in the absence of de novo protein synthesis. The term was originally used exclusively for viral genes where immediate-early referred to transcription immediately following virus integration into the host cell. It is also used to describe cellular genes which are expressed immediately after resting cells are stimulated by extracellular signals such as growth factors and neurotransmitters. (12 Dec 1998) |
| history of medicine, early modern | The period of the history of medicine from 1451 through 1600 a.d. History of medicine, 15th cent. And history of medicine, 16th cent. Are also available. (12 Dec 1998) |
| immediate early gene | Class of genes whose expression is low or undetectable in quiescent cells, but whose transcription is activated within minutes after extracellular stimulation such as addition of a growth factor. C fos and c myc proto-oncogenes were among the first IEG's to be identified. Many IEG's encode transcription factors and therefore have a regulatory function. (18 Nov 1997) |
| immediate-early proteins | Proteins that are coded by immediate-early genes, in the absence of de novo protein synthesis. The term was originally used exclusively for viral regulatory proteins that were synthesised just after viral integration into the host cell. It is also used to describe cellular proteins which are synthesised immediately after the resting cell is stimulated by extracellular signals. (12 Dec 1998) |
| early | 1. In advance of the usual or appointed time; in good season; prior in time; among or near the first; opposed to late; as, the early bird; an early spring; early fruit. "Early and provident fear is the mother of safety." (Burke) "The doorsteps and threshold with the early grass springing up about them." (Hawthorne) 2. Coming in the first part of a period of time, or among the first of successive acts, events, etc. "Seen in life's early morning sky." (Keble) "The forms of its earlier manhood." (Longfellow) "The earliest poem he composed was in his seventeenth summer." (J. C. <philosophy> Shairp) Early English See the Note under English. Early English architecture, the first of the pointed or Gothic styles used in England, succeeding the Norman style in the 12th and 13th centuries. Synonym: Forward, timely, not late, seasonable. Origin: OE. Earlich. See Early. Source: Websters Dictionary (01 Mar 1998) |
| early ambulation | Procedure characterised by a shorter period of hospitalization or recumbency or by more rapid mobilization than is normally practiced. (12 Dec 1998) |
| early deceleration | Slowing of the foetal heart rate early in the uterine contraction phase, denoting compression of the foetal head. (05 Mar 2000) |
| early development | An early stage in the life cycle of a bacteriophage (a virus which infects bacteria) that occurs after infection but before replication of the bacteriophage genome. (09 Oct 1997) |
| early diastolic murmur | A murmur that begins with the second heart sound, as the murmur of aortic insufficiency. (05 Mar 2000) |
| early gene | <genetics, molecular biology> Genes that are expressed soon after viral infection of a host cell. (18 Nov 1997) |
| early infantile autism | A severe emotional disturbance of childhood characterised by qualitative impairment in reciprocal social interaction and in communication, language, and social development. Synonym: autistic disorder, childhood schizophrenia, early infantile autism, Kanner's syndrome. (05 Mar 2000) |
| early labour | <obstetrics> The onset of uterine (labour) contractions after 32 weeks gestation but before 38 weeks gestation. (27 Sep 1997) |
| early latent syphilis | Infection with Treponema pallidum, the organism of syphilis, after the primary and secondary phases have subsided, during the first year after infection, before any manifestations of tertiary syphilis have appeared. (05 Mar 2000) |
