superoxide production by thylakoids during chilling and its implication in the susceptibility of plants to chilling-induced photoinhibition.	factors influencing the rate of superoxide (o 2 (-) ) production by thylakoids were investigated to determine if increased production of the radical was related to injury induced by chilling at a moderate photon flux density (pfd). plants used were spinacia oleracea l., cucumis sativus l. and nerium oleander l. grown at either 200° c or 45° c. superoxide production was determined by electron-spin-resonance spectroscopy of the (o 2 (-) )-dependent rate of oxidation of 2-ethyl-1-hydroxy-2,5,5-trim ...	1991	24193624
digoxin-specific fab fragments in the treatment of oleander toxicity in a canine model.	to examine the efficacy of digoxin-specific fab fragments (dsfab) in the treatment of experimentally induced nerium oleander cardiac glycoside toxicity in a dog model.	1991	1928877
the effect of changing the composition of phosphatidylglycerol from thylakoid polar lipids of oleander and cucumber on the temperature of the transition related to chilling injury.	the composition and phase behavior of some lipid classes and mixtures of thylakoid polar lipids were measured to investigate their role as determinants of the temperature of the transition associated with chilling injury. for nerium oleander l., a plant which acclimates to growth temperature, a mixture of the phosphatidylglycerol (pg) and sulfoquinovosyldiacylglycerol (sqdg) showed transition temperatures of 22° and 10° c for plants grown at 45° and 20° c, respectively. this difference was simil ...	1990	24196686
zeaxanthin and the induction and relaxation kinetics of the dissipation of excess excitation energy in leaves in 2% o(2), 0% co(2).	the relationship between the carotenoid zeaxanthin, formed by violaxanthin de-epoxidation, and nonphotochemical fluorescence quenching (q(np)) in the light was investigated in leaves of glycine max during a transient from dark to light in 2% o(2), 0% co(2) at 100 to 200 micromoles of photons per square meter per second. (a) up to a q(np) (which can vary between 0 and 1) of about 0.7, the zeaxanthin content of leaves was linearly correlated with q(np) as well as with the rate constant for radiati ...	1989	16666893
detection of poisoning by plant-origin cardiac glycoside with the abbott tdx analyzer.	cardiac glycoside poisoning caused by ingestion of plant material is common in tropical and sub-tropical areas. in evaluating the use of the abbott tdx digoxin ii assay to detect such cases of poisoning, we found it a rapid and convenient method for confirming the ingestion of glycosides from the plants nerium oleander, thevetia peruviana, and adonis microcarpa, and from the toad bufo marinus. here we report some clinical cases illustrating our experience with the use of this assay, and describe ...	1989	2914377
oleander poisoning: treatment with digoxin-specific fab antibody fragments.	a 37-year-old man presented two hours after the ingestion of "a handful" of oleander leaves (probably nerium oleander) in a suicide attempt. cardiotoxicity was evidenced by the presence of bradycardia (rate, 30 to 45) with sinoatrial nodal arrest and junctional escape consistent with a cardiac glycoside effect. the patient was treated empirically with a single dose of five vials (200 mg) of digoxin-specific fab antibody fragments (digibind). the pretreatment digoxin level was 1.5 ng/ml. after tr ...	1988	3382077
phase transitions in thylakoid polar lipids of chilling-sensitive plants: a comparison of detection methods.	the phase behavior of thylakoid polar lipids from plants sensitive to chilling injury was investigated by calorimetry, electron spin resonance spectroscopy of spin labels, and fluorescence intensity after labeling with trans-parinaric acid. the plants used were oleander (nerium oleander), mung bean (vigna radiata l. var mungo), and tomato (lycopersicon esculentum cv grosse lisse). for all plants the initiation temperature for the calorimetric exotherm was coincident (+/-1 degrees c) with the tra ...	1986	16664677
naturally occurring cardiac glycosides.	cardiac glycoside poisoning from the ingestion of plants, particularly of oleanders, occurs with reasonable frequency in tropical and subtropical areas. we have assessed a variety of plant specimens for their cardiac glycoside content by means of radioimmunoassays with antibodies that differ in their specificity for cardiac glycosides. significant amounts of immunoreactive cardiac glycoside were found to be present in the ornamental shrubs: yellow oleander (thevetia peruviana); oleander (nerium ...	1986	3086679
regulation of 3-indoleacetic acid production in pseudomonas syringae pv. savastanoi. purification and properties of tryptophan 2-monooxygenase.	the oxidative decarboxylation of l-tryptophan to yield 3-indoleacetamide, catalyzed by tryptophan 2-monooxygenase, represents a controlling reaction in the synthesis of indoleacetic acid by pseudomonas savastanoi (pseudomonas syringae pv. savastanoi), a gall-forming pathogen of olive (olea europea l.) and oleander (nerium oleander l.). production of indoleacetic acid is essential for virulence of the bacterium in its hosts. tryptophan 2-monooxygenase was characterized to determine its role in in ...	1985	3997822
a case report of nerium oleander poisoning in cattle.	nerium oleander leaves caused the death within 36 hours of 7 of 17 cattle which had access to boughs of the plant. arrhythmia and auriculo-ventricular block at ecg were found in three cattle surviving on day 4. in one animal which died on day 4, postmortem examination revealed subendocardial and abomasal hemorrhages. epidermic tissues of the leaves of n oleander were found in the rumen content. recovery occurred in the three animals with marked cardiac signs.	1984	6540502
comparison of water potentials measured by in situ psychrometry and pressure chamber in morphologically different species.	leaf water potentials measured by in situ psychrometry were compared with leaf water potentials measured by the pressure chamber technique at various values of water potential in helianthus annuus, helianthus nuttallii, vigna unguiculata, nerium oleander, pistacia vera, and corylus avellana. in v. unguiculata, the leaf water potentials measured by the in situ psychrometer oscillated at the same periodicity as, and proportional to, the leaf conductance. in all species, potentials measured by in s ...	1984	16663415
the responses of stomata and leaf gas exchange to vapour pressure deficits and soil water content : i. species comparisons at high soil water contents.	the responses of photosynthesis, transpiration and leaf conductance to changes in vapour pressure deficit were followed in well-watered plants of the herbaceous species, helianthus annuus, helianthus nuttallii, pisum sativum and vigna unguiculata, and in the woody species having either sclerophyllous leaves, arbutus unedo, nerium oleander and pistacia vera, or mesomorphic leaves, corylus avellana, gossypium hirsutum and prunus dulcis. when the vapour pressure deficit of the air around a single l ...	1984	28311208
the effect of host plant phenology on reproduction of the milkweed bug, oncopeltus fasciatus, in tropical florida.	a field study of the relationship between host plant phenology and the reproductive pattern of the large milkweed bug, oncopeltus fasciatus, was conducted in south florida. since o. fasciatus need seeds of either milkweed or nerium oleander plants to reproduce, reproduction takes place on only those host plants that are producing seed pods.two of four major host plants, asclepias incarnata and sarcostemma clausa fruit seasonally, producing pods in early autumn and early winter, respectively. the ...	1982	28310113
