| van Horne's canal | <anatomy> The major efferent lymph duct into which lymph from most of the peripheral lymph nodes drains. Recirculating lymphocytes that have left the circulation in the lymph node return to the blood through the thoracic duct. (18 Nov 1997) |

| Van Slyke's formula | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula.

| ellis-van creveld syndrome | <radiology> Chondro-ectodermal dysplasia, hereditary (especially seen in Amish of Pennsylvania), polydactyly (100%), congenital heart disease (60%), abnormalities of cutaneous appendages (skin, hair, nails) More info: Ellis-van Creveld syndrome (12 Dec 1998) |
| exon trapping vincent van buren | <molecular biology, technique> A technique used to identify vector. The vector has two exons that are normal, splicedtogether in a transcript.Fragments of DNA can be inserted into the intron, and when the insert is an exon, the exon is splicedinto the transcript, thereby giving a longer transcript that can be detected by Northern blotanalysis.
