| steady-state rate | The velocity of an enzyme-catalyzed reaction in which, over the time course of the study, the concentration of any enzyme species is constant (i.e., for an enzyme-substrate binary complex, ES, d[ES]/dt&apprxeq;00; for this to hold true, the total enzyme concentration must be much less than the initial substrate concentration. Synonym: steady-state rate. (05 Mar 2000) |

| decerebrate state | A peculiar neurologic condition elicited in vertebrates as a consequence of the elimination of brain function by transecting the brainstem or interrupting function by other techniques. Clinically, brain damage can result in neurological signs resembling those of a decerebrate animal. The state consists of exaggerated postures, grossly abnormal reflexes, convulsions, and extreme muscular rigidity and spasticity. (12 Dec 1998) |
| decorticate state | A unilateral or bilateral postural change, consisting of the upper extremities flexed and adducted and the lower extremities in rigid extension; due to structural lesions of the thalamus, internal capsule, or cerebral white matter. Synonym: decorticate state. (05 Mar 2000) |
| dreamy state | The saemiconscious state associated with an epileptic attack. Synonym: absent state. (05 Mar 2000) |
| imperfect state | In fungi, the state or stage at which only asexual spores such as conidia are formed; most such species are classified as Deuteromycetes (Fungi Imperfecti). (05 Mar 2000) |
| triplet state | A second excited state of a molecule (e.g., chlorophyll) produced by absorption of light to produce the singlet state, then loss of some energy (fluorescence) to arrive at the longer-lived triplet state The molecule may remain sufficiently long in the triplet state for a second activating light quantum to be effective in producing a "second triplet" state, obviously at still a higher level of excitation, hence reactivity. Alternatively, it may lose the triplet state energy directly and return to the ground state. (05 Mar 2000) |
| eunuchoid state | An imprecisely delineated condition of a male manifesting signs of inadequate androgen secretion during adolescent growth, regardless of the cause; usually referring to long legs, short trunk, and boyish beardless faces. (05 Mar 2000) |
| twilight state | A condition of disordered consciousness during which actions may be performed without the conscious volition of the individual and with no memory of such actions. Compare: somnambulic epilepsy. (05 Mar 2000) |
| excited state | <chemistry, radiobiology> An atom or nucleus which possesses more energy than its ground state energy. (16 Dec 1997) |
| lacunar state | The presence of lacunes in the brain. One of the major factors underlying cerebrovascular disease; high correlation with hypertension and atherosclerosis. Symptomatic forms include pure motor hemiplegia and pure hemisensory syndrome; multiple lacunar infarcts are the most common cause of pseudobulbar palsy. (05 Mar 2000) |
| local excitatory state | Increased irritability of a nerve fibre or muscle fibre which is produced by an ineffective electrical stimulus; summation of the stimuli may occur, resulting in a propagated impulse if two or more subliminal stimuli are applied in rapid succession. (05 Mar 2000) |
