| selective medium | <cell culture> A medium which allows the growth of certain types of microorganisms in preference to others. For example: an antibiotic-containing medium allows the growth of only those microorganisms which are resistant to this antibiotic. (09 Oct 1997) |
| selective memory | <psychology> Reception or retrieval of only some of the events in an experience. (05 Mar 2000) |
| selective oestrogen-receptor modulator | <pharmacology> An antioestrogen which possesses some, but not all, of the actions of oestrogen. For example, raloxifene (evista) is classified as a SERM because it prevents bone loss (like oestrogen) and lowers serum cholesterol (like oestrogen) but (unlike oestrogen) does not stimulate the endometrial lining of the uterus. Acronym: SERM (17 Jul 2002) |
| selective reduction | <obstetrics> A technique for intrauterine termination of one or more foetuses while leaving one or more foetuses undisturbed, usually in pregnancies with foetal anomalies or with multiple gestations. (05 Mar 2000) |
| selective serotonin reuptake inhibitor | <pharmacology> This is a class of drug that are used as antidepressants. Functionally, they increase the levels of serotonin in the body. These drugs can be dangerous if they are mixed with other drugs such as other antidepressants, illicit drugs (LSD, cocaine, methamphetamine), some antihistamines (Seldane, Histmanal), some antibiotics, and calcium channel blockers. Side effects include lethargy, confusion, flushing, sweating and muscle spasms. Overdose can cause damage to red blood cells, breathing problems and kidney damage. Examples include: Prozac, Zoloft and Paxil. Acronym: SSRI (12 Jan 1998) |
| selective stain | <technique> A stain that colours one portion of a tissue or cell exclusively or more deeply than the remaining portions. (05 Mar 2000) |
| selectivity | <pharmacology> The degree to which a dose of a drug produces the desired effect in relation to adverse effects. (18 Nov 1997) |
| selector gene | <molecular biology> A group of genes that determines which part of a developmental pattern cells will be allocated within a developmental segment. (18 Nov 1997) |
| selective amnesia |
loss of memory for a group of related events but not for other events occurring during the same period of time.

| selection bias |
Selection bias is the error of distorting a statistical analysis by pre- or post-selecting the samples. Typically this causes measures of statistical significance to appear much stronger than they are, but it is also possible to cause completely illusory artifacts. Selection bias can be the result of scientific fraud which manipulate data directly, but more often is either unconscious or due to biases in the instruments used for observation. ...

| selective |
Natural selection is a process by which biological populations are altered over time, as a result of the propagation of heritable traits that affect the capacity of individual organisms to survive and reproduce. It is one of several mechanisms that give rise to the evolution of biological species (other mechanisms include genetic drift and gene flow. ...

| selection |
In the context of evolution, certain traits or alleles of a species may be subject to selection. Under selection, individuals with advantageous or "adaptive" traits tend to be more successful than their peers reproductively--meaning they contribute more offspring to the succeeding generation than others do. Selection therefore increases the prevalence of these traits, because offspring inherit traits from their parents. ...

| selective serotonin reuptake inhibitor |
Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressants. They act within the brain to increase the amount of the neurotransmitter, serotonin (5-hydroxytryptamine or 5-HT), in the synaptic gap by inhibiting its reuptake. One notable characteristic of SSRIs is that, unlike other classes of antidepressants, SSRIs were rationally designed drugs. Instead of being discovered by accident, SSRIs were specifically designed while considering the biological causes of depression. ...
