What's the difference between invariable and unvariable?
(a.) Not given to variation or change; unalterable; unchangeable; always uniform.
(n.) An invariable quantity; a constant.
(1) In X-irradiated litters, almost invariably, the incidence of anophthalmia was higher in exencephalic than in nonexencephalic embryos and the ratio of these incidences (relative risk) decreased toward 1 with increasing dose.
(2) On the other hand, the injection of minute quantities of endotoxin into PbAc(2)-sensitized rats invariably resulted in disseminated intravascular coagulation, apparently via a complete activation of the intrinsic pathway.
(3) The cytoplasmic and membrane spanning domains of galactosyltransferase were found to be sufficient to retain all of the hybrid invariant chain in trans Golgi cisternae as judged by indirect immunofluorescence, treatment with brefeldin A and immuno-electron microscopy.
(4) The purification and concentration of these viruses in their monomeric forms is hazardous when conventional "tube" rotors are used since they invariably result in dissociation and aggregation of the virus particles.
(5) In contrast, cases of parkinsonism beginning before age 21 years were invariably familial.
(6) Examination of the two types of tissue fragments revealed that IS-treated ICMs almost invariably retained viable endoderm cells whereas MS-isolated ectoderms did so only exceptionally.
(7) It is suggested that a general manner of folding may be a common feature of the heterogeneous population of kappa-chains: one bridge which folds an invariable stretch of the chain, another bridge which folds a stretch that varies from protein to protein, and a bridge at the C-terminus which is the interchain link.
(8) An obsessional artist who was an enemy of all institutions, cinematic as well as social, and whose principal theme was intolerance, he invariably gets delivered to us today by institutions - most recently the National Film Theatre, which starts a Dreyer retrospective this month - that can't always be counted on to represent him in all his complexity.
(9) Patients with anti-NC1 antibodies were characterised by linear immune deposits along the glomerular basement membrane and the clinical outcome was invariably grim.
(10) The PCR amplified a 375-bp DNA fragment which was cloned and sequenced; the deduced amino acid sequence had significant identity with known TS sequences, including strict conservation of all phylogenetically invariant TS amino acid residues.
(11) Using confirmatory factor analysis on an independent sample (N = 377), these dimensions were tested for factorial invariance across spouse and nonspouse caregivers and between caregivers of persons with cancer and those caring for persons with Alzheimer's disease.
(12) The species invariance of this lysine residue, number 175, and the substantial conservation of adjacent sequence support the probability for a functional role in catalysis of the lysyl epsilon-amino group.
(13) Under these assumptions, any time-invariant variable may behave like a metabolite concentration, i.e.
(14) However, in conical cells the new oral apparatus and fission line form well posterior to the cell equator, so the opisthes are invariably smaller than proters.
(15) Unlike posterior tympanoplasty, this technique makes it possible to meticulously remove the osteitic bone invariably found in the facial recess when there is infection of the retraction pocket.
(16) Limited data indicates that, while enhanced thermal stability invariably results, the optimum temperature for catalysis may not change.
(17) The relative invariance of the allometric baselines of wing morphology in nature is most easily explained as the result of continuous natural selection around a local optimum of functional design.
(18) When the paper had some explaining to do, Kuttner was invariably asked to carry out that task.
(19) We found that NS1 cells express correctly sized mRNA for the MHC class II genes A alpha, E alpha and the invariant chain.
(20) When we reached our summit, or whatever spot was deemed by my father to be of adequately punishing distance from the car to deserve lunch, Dad would invariably find he had forgotten his Swiss army knife (looking back, I begin to doubt he ever had one) and instead would cut cheese into slices with the edge of his credit card.
(1) Essential features are the use of reagent grade chemicals only, a pretreatment solution to ensure optimal impregnation of different organs from different animals and species, and an unvarying procedure.
(2) In the preimplantation period, ER patterns remained unvarying on days 2-6 of gestation in both cytoplasmic and nuclear compartments; their levels in nuclear fraction were significantly higher from day 3 onwards while, total cytoplasmic ER concentrations were higher from day 4 of gestation compared with the values obtained for secretory phase tissues from normal ovulatory cycles.
(3) The sum of life events, several SCL-90R scores and the scores of distress in relationships were already elevated in hypomanics 7 years before diagnosis of hypomania, indicating an increased activity level, a generalized increase in neuroticism, and a relatively unvarying behaviour pattern in social relationships.
(4) The action of E2 on the pituitary in the presence of unvarying GnRH pulsation may, however, be limited to an early transient inhibition of responsiveness to GnRH, with no subsequent direct stimulation during the period of the surge.
(5) This relation remained substantially unvaried when nonsmokers and smokers were analyzed separately.
(6) In terms of the present model, B and deltaVh are explicit functions of the internal K+ concentrations and are thus constant only as long as this is unvaried.
(7) When MgCl2 replaced MnCl2, the kinetic parameters for oxaloacetate remained substantially unvaried, whereas the Km and Vm values for L-malate have been found to vary depending on the metal ion.
(8) It is suggested that the survival advantage and hence the prevalence of sickle cell trait may be greatest in some hyperendemic areas and less where malaria transmission is extremely high or when it is high and unvaried.
(9) In addition, the reanalysed data show that yield strain is strongly strain-rate dependent, but that Young's modulus is rather unvarying over physiological strain rates.
(10) A series of 24 visually evoked potentials was obtained from a normnal human subject under a set of unvarying experimental conditions.
(11) Also intracellular Na+ and K+ levels remained unvariable.
(12) In athyreotic insulin-administered dogs, the circulating T4 and T3 remain at more or less unvarying values, the plasma disappearance slope of radiothyroxine is not altered.
(13) Simple unvarying or repetitive speech sounds were not sufficient to induce the irrelevant speech effect (Experiment 1): in addition, simple analogues of speech, possessing regular or irregular envelopes and using a range of carriers, failed to imitate the action of speech (Experiment 2).
(14) Head circumference greater than the 90th percentile for age was associated with unvarying behavior and clumsiness; tactile agnosia with unvarying behavior; asymmetry of the eyes with hyperactivity; and asymmetrical position of the child's head with underachievement.
(15) The 188 phylogenetically informative sites (i.e., those positions that neither were unvaried nor had only autapomorphic substitutions) supported a single tree topology 481 steps in length with a consistency index of 0.65 in which the monophyly of the Apicomplexa was supported.
(16) Exposure of male edible dormice all year round to an unvarying photoperiod and warm temperature disrupted their biological cycles; hibernation was almost completely suppressed, and short lived infradian cycles of body weight, and of plasma testosterone and thyroxine were measured instead of the normal annual pattern.
(17) In 70% of the cases an improvement was observed in the symptomatology and a decrease in total serum IgE, while specific IgE remained unvaried.
(18) Repeated measures of CSF 5-HIAA and HVA in another 22 males living in unvarying settings showed that individual differences in these measures persisted over time.
(19) The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior.
(20) In LRP rats gonadotropin levels remained low and unvarying throughout the experiment; PRL levels were high in the morning, low at 1300 h, and then surged in the afternoon.
