What's the difference between quenchable and thirst?
Quenchable
Definition:
(a.) Capable of being quenched.
Example Sentences:
(1) The most important effect is produced by beta subunit-mutation which decreases the quenchable fraction, one-third to one-half tryptophans being no longer accessible to iodide.
(2) Denaturation with urea or guanidine HCl plus dithiothreitol increases the fraction of quenchable fluorescence even more, but still a small fraction, about 7-13%, is buried.
(3) To more precisely define the position of the quenchable tryptophan, the experiment was repeated with lipids with the bromine atoms at the 4,5-, 6,7- or 9,10-positions.
(4) Stern-Volmer plots of the quenching data are nonlinear and indicate that there is more than one quenchable conformation of the calcium-free protein.
(5) In contrast, upon complete removal of calcium, the fluorescence is completely quenchable as shown by extrapolation of the data to infinite iodide concentration.
(6) Although the enzyme contains three tryptophan residues, Stern-Volmer plots are linear with all the fluorescence quenchable at high acrylamide concentrations.
(7) Phosphorescent probes are described that are quenchable by dioxygen and that partition into membranes.
(8) A model is presented in which the quenchability of a buried tryptophan is inversely related to the distance from the surface when diffusion through the protein is the rate-limiting step.
(9) A small decrease was observed in the quenchability of a fluorescent probe attached to the sulphydryl group and a small increase in the uptake of an hydrophobic probe.
(10) However, as opposed to native S-1, in heat-treated S-1 the addition of ATP does not induce an increase in tryptophan fluorescence, and, in the case of the treated species, the fluorescence of 1,N6-ethenoadenosine 5'-diphosphate added to the mixture is quenchable by acrylamide.
(11) Apparent quenching constants are wavelength-dependent; global analysis reveals a quenchable component corresponding to the 4.5 ns component and an "unquenchable" component superposing the 0.6-ns spectrum.
(12) At pH values close to the isoelectric points of the enzymes the electrostatic parameter suggests that the environment of the quenchable tyrosines in L-asparaginase is somewhat more positive than in ribonuclease.
(13) A really remarkable finding of studies of protein phosphorescence is that there is such variability both in phosphorescence lifetime and quenchability.
(14) The differential effectiveness of external quenchers on unliganded and liganded CPK allows the determination of the ligand binding equilibria by fluorescence-quenchability titration.
(15) Plaques are counted under a fluorescence microscope and the preparations can be made permanent and virtually non-quenchable by drying.
Thirst
Definition:
(n.) A sensation of dryness in the throat associated with a craving for liquids, produced by deprivation of drink, or by some other cause (as fear, excitement, etc.) which arrests the secretion of the pharyngeal mucous membrane; hence, the condition producing this sensation.
(n.) Fig.: A want and eager desire after anything; a craving or longing; -- usually with for, of, or after; as, the thirst for gold.
(n.) To feel thirst; to experience a painful or uneasy sensation of the throat or fauces, as for want of drink.
(n.) To have a vehement desire.
(v. t.) To have a thirst for.
Example Sentences:
(1) The possibility that the pressor effects of angiotensin II influence angiotensin-induced thirst was investigated in dogs pretreated with hexamethonium.
(2) The results suggest that angiotensin and cholinergic receptors in the brain have a physiological role in thirst.
(3) Experiments in which this method has been applied to the measurement of hunger and thirst in doves are outlined, and the results are discussed in terms of their implications for motivation theory in general.
(4) The subjects described the thirst sensations as mainly due to a dry unpleasant tasting mouth, which was promptly relieved by drinking.
(5) To determine whether centrally released vasopressin influences thirst, observations of osmotic thirst threshold, osmotic load excretion and postloading restitution of plasma osmolality were made in dogs in control experiments and during infusion of AVP antagonists into the third ventricle.
(6) The results of these studies, considered as a whole, support the view that McCleary's osmotic postingestional satiety signal acts as an intestinal distention signal rather than by inducing thirst.
(7) These findings suggest the following sequence of events: impaired A-II production caused impairment of thirst perception, renal-concentrating capacity, and AVP secretion and contributed to development of hypernatremic dehydration in these elderly patients.
(8) We postulated that the high salt content of CF patients' sweat and the consequent absence of body-fluid hyperosmolality during a long episode of sweating might deprive such patients of a thirst stimulus.
(9) The fall in plasma osmolality associated with human pregnancy is accounted for entirely by a lowering of the osmotic thresholds for thirst and vasopressin release.
(10) To investigate further the stimulus for this effect, its specificity, and association with thirst, six volunteers were deprived of water for 24 h and given a salt load on two separate occasions.
(11) Beliefs best differentiating among the three groups were: (1) superiority of taste of their "own" sodas, (2) perceived efficiency to quench thirst, and (3) perceived compatibility with other menu items.
(12) In the absence of conflict, there was no difference in the satisfaction of the thirst and the defensive motivation in animals adapted to hypoxia and in controls.
(13) A patient developed extreme thirst and polyuria after massive bleeding and prolonged shock due to placenta previa percreta with bladder invasion.
(14) The sensation of thirst did not correlate with plasma osmolality and was not always related to plasma AVP concentration.
(15) Photograph: Nerissa Sparkman This being Dublin, visitors to Stoneybatter will find no shortage of opportunities to slake their thirst.
(16) We describe a case of diabetes insipidus after head injury in which thirst persisted despite treatment with DDAVP and normal plasma osmolality.
(17) Basal levels of serum osmolality and thirst were significantly higher in alcoholics compared with controls, yet actively drinking alcoholics at the start of the study had normal vasopressin (AVP) levels, plasma angiotensin II (Ang II), plasma renin activity, plasma aldosterone (Aldo), and plasma catecholamines.
(18) Brin and Page remain joint presidents, Brin in charge of technology, Page responsible for product launches, but the rapid growth of recent years has been steered by chief executive Eric Schmidt, 53, who came on board in 2001 as the commercial 'brain', negotiating the founders' evangelism and the shareholders' thirst for profits.
(19) Involvement of the hypothalamus and pituitary can cause primary polydipsia and disordered regulation of thirst; diabetes insipidus, impaired secretion of anterior pituitary hormones (with clinically apparent hypothyroidism, hypogonadism, hypoadrenalism, or impaired growth), and increases in serum prolactin may also result.
(20) Previous reports demonstrated that hypothalamic stimulation may elicit either eating, drinking, or gnawing and emphasized both the specificity of the neural circuits mediating these behaviors and the similarity to behavior during natural-drive states such as hunger and thirst.
