| DGCR | DiGeorge syndrome chromosome region |
|---|---|
| ER | efficiency ratio; epigastric region; ejection rate; electroresection; emergency room; endoplasmic re... |
| EWSR | Ewing sarcoma breakpoint region |
| HSR | Harleco synthetic resin; heated serum reagin; homogeneously staining region |
| hv | hypervariable region |
| pubic region | The lower central region of the abdomen below the umbilical region. Synonym: hypogastrium, regio pubica. (05 Mar 2000) |
|---|---|
| homogeneously staining region | <molecular biology> A region on a chromosome which, when stained, is uniform in appearance. (Normally, a stained chromosome shows a banding pattern.) Homogeneously staining regions contain multiple copies of a single gene. (09 Oct 1997) |
| Shine Dalgarno region | A poly purine sequence found in bacterial mRNA about 7 nucleotides in front of the initiation codon, AUG. The complete sequence is 5' AGGAGG 3' and almost all messengers contain at least half of this sequence. It is complementary to a highly conserved sequence at the 3' end of 16s ribosomal RNA, 3' UCCUCC 5' and it is thought to be involved in the binding of the mRNA to the ribosome. (18 Nov 1997) |
| hypervariable region | <immunology> Those regions of the heavy or light chains of immunoglobulins in which there is considerable sequence diversity within that set of immunoglobulins in a single individual. These regions specify the antigen affinity of each antibody. (18 Nov 1997) |
| hypochondriac region | <anatomy> The region on each side of the abdomen covered by the costal cartilages; it is lateral to the epigastric region. Synonym: regio hypochondriaca, hypochondrium. (05 Mar 2000) |
| S region | <molecular biology> The nonMHC gene in the midst of the H 2 major histocompatability complex of the mouse genome that codes for complement component C4. Sometimes confusingly known as the gene for the type III MHC product in mice. (12 Jan 1998) |
| nasal region | The region of the nose. Synonym: regio nasalis. (05 Mar 2000) |
| sternocleidomastoid region | The region overlying the sternocleidomastoid muscle, including the lesser supraclavicular fossa. Synonym: regio sternocleidomastoidea. (05 Mar 2000) |
| suboccipital region | Upper back of neck, inferior to occipital region of head and above the level of the second cervical vertebra; overlies (or includes, deeply) the suboccipital triangle. (05 Mar 2000) |
| nuchal region | The back of neck, including the suboccipital region. Synonym: regio nuchalis, nuchal region, posterior neck region, regio cervicalis posterior. (05 Mar 2000) |
| nucleoid region | Area in a prokaryotic cell that contains the genetic material. (14 Nov 1997) |
| nucleolus organiser region | The chromosome region which is active in nucleolus formation and which functions in the synthesis of ribosomal RNA. (12 Dec 1998) |
| sural region | The muscular swelling of the back of the leg below the knee, formed chiefly by the bellies of the gastrocnemius and soleus muscles. Synonym: regio suralis, sura, calf. (05 Mar 2000) |
| deltoid region | The lateral aspect of the shoulder demarcated by the outlines of the deltoid muscle. Synonym: regio deltoidea. (05 Mar 2000) |
| switch region | <molecular biology> The nucleotide sequences in heavy chain immunoglobulin genes located in the introns at the 5' end of each CH locus concerned with DNA recombination events that lead to changes in the type of heavy chain produced by a B-cell, for example IgM to IgG switching. These regions are highly conserved sequences. See: isotype switching. (19 Jan 1998) |
