| splitting | In chemistry, the cleavage of a covalent bond, fragmenting the molecule involved. (05 Mar 2000) |
|---|---|
| splitting enzymes | Enzyme's that, like aldolases, catalyze the conversion of a molecule into two smaller molecules without the addition or subtraction of any atoms. (05 Mar 2000) |
| splitting of heart sounds | The production of major components of the first and second heart sounds (rarely the third and fourth) due to contribution by the left-sided and right-sided valves; thus, the first heart sound would have a mitral and a tricuspid component and the second heart sound has an aortic and pulmonic component. The latter are best appreciated during respiration, with inspiration delaying the pulmonic component and producing an earlier aortic component. (05 Mar 2000) |
| kinase-splitting membranal proteinase | <enzyme> Brush-border membrane proteinase; specifically clips the native form of the catalytic subunit of camp-dependent protein kinase Registry number: EC 3.4.99.- Synonym: ksm proteinase (26 Jun 1999) |
| paradoxical | Occurring at variance with the normal rule. (18 Nov 1997) |
| paradoxical contraction | A tonic contraction of the anterior tibial muscles when a sudden passive dorsal flexion of the foot is made. (05 Mar 2000) |
| paradoxical diaphragm phenomenon | In pyopneumothorax, hydropneumothorax, and some cases of injury, the diaphragm on the affected side rises during inspiration and falls during expiration. (05 Mar 2000) |
| paradoxical embolism | Passage of a clot (thrombus) from a vein to an artery. When clots in veins break off (embolise) , they travel first to the right side of the heart and, normally, then to the lungs where they lodge. The lungs act as a filter to prevent the clots from entering the arterial circulation. However, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism. Once in the arterial circulation, a clot can travel to the brain, block a vessel there, and cause a stroke (cerebrovascular accident). Because of the risk of stroke from paradoxical embolism, it is usually recommended that even small atrial septal defects be repaired. Also called crossed embolism. (12 Dec 1998) |
| paradoxical extensor reflex | <clinical sign> Extension of the great toe and abduction of the other toes instead of the normal flexion reflex to plantar stimulation, considered indicative of pyramidal tract involvement ("positive" Babinski). Synonym: Babinski reflex, Babinski's phenomenon, great-toe reflex, paradoxical extensor reflex, toe phenomenon. (05 Mar 2000) |
| paradoxical flexor reflex | Dorsal flexion of the great toe produced by firm lateral pressure on the calf muscles. Synonym: paradoxical flexor reflex. (05 Mar 2000) |
| paradoxical incontinence | Involuntary loss of urine associated with overdistention of the bladder, with or without a detrusor contraction. Synonym: paradoxical incontinence. (05 Mar 2000) |
| paradoxical movement of eyelids | Spontaneous, involuntary elevation or lowering of the eyelids, associated with movement of extraocular muscles or muscles of mastication (external pterygoids). See: jaw winking. (05 Mar 2000) |
| paradoxical patellar reflex | A tap on the patellar tendon causes contraction of the adductor, sudden passive extension of the leg causes a contraction of the extensor muscles of the leg. (05 Mar 2000) |
| paradoxical pulse | An exaggeration of the normal variation in the pulse volume with respiration, becoming weaker with inspiration and stronger with expiration; characteristic of cardiac tamponade, rare in constrictive pericarditis; so called because these changes are independent of changes in the cardiac rate as measured directly or by electrocardiogram. Synonym: pulsus paradoxus, pulsus respiratione intermittens. (05 Mar 2000) |
| paradoxical pupil | See: paradoxical pupillary reflex. Pinhole pupil, an extremely constricted pupil. (05 Mar 2000) |
