| hemizona assay | <investigation> The hemizona assay is a laboratory test of the ability of sperm to penetrate into a human egg, first the egg is split in half, then one half is tested against the husband's sperm and the other half against sperm from a fertile man. (09 Oct 1997) |
| hemizygosity | The state of being hemizygous. (05 Mar 2000) |
| hemizygote | <cell biology, genetics> Nucleus, cell or organism that has only one of a normally diploid set of genes. In mammals the male is hemizygous for the X chromosome. (18 Nov 1997) |
| hemizygotic | <genetics> A situation within a cell where only one copy of a gene or group of genes is present instead of the usual two copies per gene in a diploid genome. The word is used as in the following example: the cell is hemizygous for gene X. (09 Oct 1997) |
| hemizygous | <genetics> A situation within a cell where only one copy of a gene or group of genes is present instead of the usual two copies per gene in a diploid genome. The word is used as in the following example: the cell is hemizygous for gene X. (09 Oct 1997) |
| hemizygous gene | <genetics> Any gene which is present as only one copy in a diploid genome, when most other genes in the genome are present as two copies. The genes on the sex chromosomes of members of the heterogametic sex of a species are all hemizygous genes (for example: in humans, males have hemizygous genes on their X and Y chromosomes because they do not have two copies of either of those chromosomes).

| hemlock | 1. <botany> The name of several poisonous umbelliferous herbs having finely cut leaves and small white flowers, as the Cicuta maculata, bulbifera, and virosa, and the Conium maculatum.

| hemming filter | <apparatus> A filter placed between two tubes attached to each other, often used with centrifuges to selectively remove a substance of interest from a mixture in one tube and deposit the substance into the other tube. (09 Oct 1997) |
| hemocyanin | <chemical> Blue, oxygen transporting, copper containing protein found in the blood of molluscs and crustacea. A very large protein with 20-40 subunits and molecular weight of 2-8 million and having a characteristic cuboidal appearance under the electron microscope. Prior to the introduction of immunogold techniques, it was used for electron microscopic localisation by coupling to antibody. (18 Nov 1997) |
| hemocyte | <haematology> Blood cell, associated with a haemocoel, particularly those of insects and crustacea. Despite the name they are more leucocyte like, being phagocytic and involved in defence and clotting of haemolymph and not involved in transport of oxygen. (18 Nov 1997) |
| hemodialysis | <nephrology, procedure> The removal of certain elements from the blood by virtue of the difference in the rates of their diffusion through a semipermeable membrane, for example, by means of a haemodialysis machine or filter. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| hemoglobin | <cell biology, haematology> Four subunit globular oxygen carrying protein of the erythrocytes of vertebrates and some invertebrates. It is a conjugated protein containing four haem groups and globin. There are two alpha and two beta chains (very similar to myoglobin) in adult humans, the haem moiety (an iron containing substituted porphyrin) is firmly held in a nonpolar crevice in each peptide chain. There are four globin polypeptide chains, designated alpha, beta, gamma, delta in the adult. Each is composed of several hundred amino acids. (08 Mar 2000) |
