| diameter obliqua | A measurement across the pelvic inlet from the sacroiliac joint of one side to the opposite iliopectineal eminence. Synonym: diameter obliqua. (05 Mar 2000) |
|---|---|
| diameter transversa | The transverse diameter of the pelvic inlet, measured between the terminal lines. Synonym: diameter transversa. (05 Mar 2000) |
| oblique diameter | A measurement across the pelvic inlet from the sacroiliac joint of one side to the opposite iliopectineal eminence. Synonym: diameter obliqua. (05 Mar 2000) |
| occipitofrontal diameter | The diameter of the foetal head from the external occipital protuberance to the most prominent point of the frontal bone in the midline. (05 Mar 2000) |
| occipitomental diameter | The diameter of the foetal head from the external occipital protuberance to the midpoint of the chin. (05 Mar 2000) |
| total end-diastolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in diastole. (05 Mar 2000) |
| total end-systolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in systole. (05 Mar 2000) |
| trachelobregmatic diameter | The diameter of the foetal head from the middle of the anterior fontanelle to the neck. (05 Mar 2000) |
| transverse diameter | The transverse diameter of the pelvic inlet, measured between the terminal lines. Synonym: diameter transversa. (05 Mar 2000) |
| zygomatic diameter | The extreme breadth of the skull at the zygomatic arches. (05 Mar 2000) |
| vaccines, conjugate | Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognised by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection. (12 Dec 1998) |
| wheat germ agglutinin-horseradish peroxidase conjugate | <chemical> The lectin wheatgerm agglutinin conjugated to the enzyme horseradish peroxidase. It is widely used for tracing neural pathways. Pharmacological action: molecular probes. (12 Dec 1998) |
| conjugate | Paired together. In chemistry, this refers to an acid and a base which can convert to each other by the gain or loss of a proton (a hydrogen nucleus), which together are called a conjugate acid-base pair. It can also refer to two liquids in equilibrium with each other. In mycology (the study of fungi), this refers to a dikaryon with two haploid nuclei in it. (09 Oct 1997) |
| conjugate acid | The protonated compound of two compounds that differ in structure only by the presence of the labile proton. (05 Mar 2000) |
| conjugate acid-base pair | In prototonic solvents (e.g., H2O, NH3, acetic acid), two molecular species differing only in the presence or absence of a hydrogen ion (e.g., carbonic acid/bicarbonate ion or ammonium ion/ammonia); the basis of buffer action. (05 Mar 2000) |
