| HIV long-terminal repeat | Regulatory sequences important for viral replication that are located on each end of the HIV genome. The ltr includes the HIV enhancer, promoter, and other sequences. Specific regions in the ltr include the negative regulatory element (nre), nf-kappa b binding sites , sp1 binding sites, tata box, and trans-acting responsive element (tar). The binding of both cellular and viral proteins to these regions regulates HIV transcription. (12 Dec 1998) |
| small bowel disease involving terminal ileum | <radiology> Crohn's, TB, Yersinia (12 Dec 1998) |
| NH2-terminal | <biochemistry> The end of a protein or polypeptide chain with the unattached amino group or the aminoacyl residue containing it. Each amino acid in the chain has an amino group on one side, which is attached to the carboxyl group (COOH group) of the previous amino acid, and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the carboxyl terminal. Synonym: NH2-terminal. (14 Aug 2000) |

| direct terminal repeat | A particular sequence of nucleotides which appears on both ends of a DNA or RNA molecule. (09 Oct 1997) |
| ileitis, terminal | Crohn's disease, a chronic inflammatory disease of the intestine involving only the end of the small intestine (the terminal ileum). Crohn's disease affects primarily the small and large intestines but which can occur anywhere in the digestive system between the mouth and the anus. Named after burrill crohn who described the disease in 1932. The disease often strikes persons in their teens or early twenties. It tends to be chronic, recurrent with periods of remission and exacerbation. In the early stages. It causes small scattered shallow crater-like areas (erosions) called apthous ulcers in the inner surface of the bowel. With time, deeper and larger ulcers develop, causing scarring and stiffness of the bowel and the bowel becomes increasingly narrowed, leading to obstruction. Deep ulcers can puncture holes in the bowel wall, leading to infection in the abdominal cavity (peritonitis) and in adjacent organs abdominal pain, diarrhoea, vomiting, fever, and weight loss can be symptoms. Crohn's disease can be associated with reddish tender skin nodules, and inflammation of the joints, spine, eyes, and liver. Diagnosis is by barium enema, barium X-ray of the small bowel, and colonoscopy. Treatment includes medications for inflammation, immune suppression, antibiotics, or surgery. (12 Dec 1998) |
