| potassium-efflux channels in extensor and flexor cells of the motor organ of samanea saman are not identical. effects of cytosolic calcium. | leaflet movements in the mimosa-family tree samanea saman stem from coordinated volume changes of cells in the leaf motor organs in the adaxial and abaxial motor cells ("flexors" and "extensors"). shrinking, initiated by dissimilar light signals in extensors and in flexors, depends in both cell types on k(+) efflux via depolarization-dependent potassium (k(d)) channels. to compare between flexor and extensor k(d) channels and to test for a possible interaction of these channels with the ca(2+)-m ... | 2000 | 11027738 |
| chemistry and biology of plant leaf movements. | the leaves of mimosa pudica l. are well known for their rapid movement when touched. recently, we were able to isolate an excitatory substance in small quantities from this plant, which consists of three different components (potassium l-malate, magnesium trans-aconitate, and dimethylammonium salt). many plants close their leaves in the evening, as if to sleep, and open them early in the morning (nyctinastic leaf movement). this circadian rhythm is known to be controlled by the biological clock ... | 2000 | 10777626 |
| antioxidant and free radical scavenging activities in extracts from medicinal trees used in the 'caatinga' region in northeastern brazil. | the in vitro antioxidant and free radical scavenging properties of bark extracts of anadenanthera macrocarpa brenan (fabaceae), astronium urundeuva engl. (anacardiaceae), mimosa verrucosa benth. (fabaceae) and sideroxylon obtusifolium t.d. penn. (sapotaceae), four trees used as anti-inflammatory agents in the brazilian state of bahia, were studied using different bioassays. the total reactive antioxidant potential (trap) of the aqueous and methanolic extracts was determined by monitoring the int ... | 1999 | 10616962 |
| role of galactomannan composition on the binary gel formation with xanthan. | the influence of the galactomannan characteristic ratios (m/g) on the temperature of gelation (tg) and the gel strength of mixtures of galactomannan with xanthan is reported. two galactomannans were investigated: one highly substituted from the seeds of mimosa scabrella (m/g = 11), and the other, less substituted, from the endosperm of schizolobium parahybae, with (m/g = 30) [ganter jlms, zawadzki-baggio sf, leitner sc, sierakowski mr, reicher f. j carbohydr chem 1993;12:753]. the xanthan:galact ... | 1999 | 10569283 |
| rhizobium etli bv. mimosae, a novel biovar isolated from mimosa affinis. | fifty rhizobial isolates from root nodules of mimosa affinis, a small leguminous plant native to mexico, were identified as rhizobium etli on the basis of the results of pcr-rflp and rflp analyses of small-subunit rrna genes, multilocus enzyme electrophoresis and dna-dna homology. they are, however, a restricted group of lineages with low genetic diversity within the species. the isolates from m. affinis differed-from the r. etli strains that orginated from bean plants (phaseolus vulgaris) in th ... | 1999 | 10555329 |
| inhalational and local anesthetics reduce tactile and thermal responses in mimosa pudica. | in reaction to a variety of stimuli, the sensitive plant mimosa pudica closes its leaflets and drops its stems. the objective was to investigate the effects of anaesthetics on the reaction of mimosa pudica to a variety of stimuli. | 1999 | 10210057 |
| an apyrase from mimosa pudica contains n5,n10-methenyl tetrahydrofolate and is stimulated by light. | an apyrase (ntp/ndpase) implicated in the response of mimosa pudica to stimuli, such as touch, has been cloned, sequenced and expressed in escherichia coli. while purifying and characterizing this enzyme, it was observed that a chromophore is associated with it, having absorption in the ultraviolet-a/blue region of the spectrum. the absorbance maximum of the chromophore, purified from the enzyme complex by gel filtration and hplc, is around 350 nm. the chromophore has been identified as n5,n10-m ... | 1998 | 9990319 |

| mimosa pudica apyrase requires polysaccharide and ca2+ for the activity. | mimosa pudica linn leaves with pulvini contain unique isoforms (i and ii) of apyrase enzyme (ec 3.6.1.5). the activity of isoform i depends on divalent cation mn2+. this isoform is associated noncovalently with the polysaccharide, containing mainly of galactose and arabinose sugars. the apparent molecular mass of these 2 isoforms are 36 and 34 kd respectively. the association of the polysaccharide with the isoform i has been found to be ca2+ dependent which is endogenously present in this isofor ... | 1998 | 9788742 |
| standardization in the field of medical image management: the contribution of the mimosa model. | this paper deals with the development of standards in the field of medical imaging and picture archiving and communication systems (pacs's), and notably concerning the interworking between pacs's and hospital information systems (his). it explains, in detail, how a conceptual model of the management of medical images, such as the medical image management in an open system architecture (mimosa) model, can contribute to the development of standards for medical image management and pacs's. this con ... | 1998 | 9617908 |
| kainate receptors exhibit differential sensitivities to (s)-5-iodowillardiine. | characterization of the role of kainate receptors in excitatory synaptic transmission has been hampered by a lack of subtype-selective pharmacological agents. (s)-5-iodowillardiine (iw), an analog of willardiine [(s)-1-(2-amino-2-carboxyethyl)pyrimidine-2,4-dione], a heterocyclic amino acid found in acacia and mimosa seeds, was previously shown to be highly potent on native kainate receptors in dorsal root ganglion neurons. we examined the responses evoked by iw from recombinant homomeric and he ... | 1998 | 9584222 |
| image management in pacs: how should they be decomposed into well-defined and interoperable industrial products? | we consider that no consensus currently exists on how pacs should be decomposed into well-defined and interoperable industrial products. we believe that this lack of consensus hampers the development of multi-vendor pacs and makes the standardization process slower. this paper tries to understand the ins and outs of these choices. to realize this we have used the mimosa functional model (euripacs project) as a reference model. we have then delineated the borders between several possible industri ... | 1997 | 9509402 |
| the enzyme involved in sulfation of the turgorin, gallic acid 4-o-(beta-d-glucopyranosyl-6'-sulfate) is pulvini-localized in mimosa pudica. | a sulfotransferase (st) which catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate (paps) to gallic acid glucoside was characterized from microsomal preparations of mimosa pudica. the product of the reaction was found to co-elute on hplc with the periodic leaf movement factor 1 (plmf-1)(gallic acid beta-d-gluco-pyranosyl-6'-sulfate). the distribution of the enzyme activity was restricted to plasma membrane preparations from primary, secondary and tertiary pulvini. the m. ... | 1997 | 9375396 |
| galactomannan from the seeds of mimosa scabrella: a scale-up process. | in view of the wide industrial applications of galactomannans as a thickening agent, those of mimosa scabrella (bracatinga), a leguminous tree abundant in southern brazil, are under investigation. seeds of bracatinga were processed on a pilot plant scale in order to obtain its galactomannan. the process consisted of successive milling, enzyme inactivation, aqueous extraction, precipitation of polysaccharide, and drying and milling. the product was obtained in 20% yield, with characteristics simi ... | 1997 | 9283028 |
| mimosine blocks cell cycle progression by chelating iron in asynchronous human breast cancer cells. | mimosine is a toxic nonprotein amino acid that is a major constituent of the tropical legumes leucaena and mimosa. mimosine has been shown to cause acute and chronic toxicosis in livestock fed from forage containing these plants. recently, mimosine has been demonstrated to reversibly block cell cycle progression in mammalian cells in culture. in this study, we compared the effects of mimosine to desferrioxamine (dfo), a well-characterized iron chelator, and found that both chemicals similarly al ... | 1996 | 8806853 |
| [effect of aging on distortion product otoacoustic emissions]. | the effect of aging on distortion product otoacoustic emissions (dpoae) was investigated in 58 ears of 32 volunteers with normal hearing dpoae levels to tones with a fixed frequency ratio (f2/f1 = 1.2) were measured with the cubdis system (mimosa acoustics, usa). age dependency of dpoae level was clearly observed both in frequency plots (dp-gram) and input-output functions. in elderly persons, dpoae levels for higher frequency primaries were significantly lower than in younger persons, when no r ... | 1996 | 8776970 |
| mimosine arrests the cell cycle after cells enter s-phase. | l-mimosine (beta-n-[3-hydroxy-4-pyridone]-alpha-aminopropionic acid)--a rare amino acid derived from mimosa and leucaena plants--arrests cells reversibly late during g1 phase or at the beginning of s-phase. if mimosine were to arrest cells immediately before s-phase, it would provide a superb tool for the investigation of the initiation of dna synthesis. therefore, we reexamined the point of action of mimosine. mitotic hela cells were released into 200 microm mimosine and grown for approximately ... | 1996 | 8598214 |
| pharmacognosy of mimosa tenuiflora (willd.) poiret. | a chemical investigation of the bark of mimosa tenuiflora (willd.) poiret, performed in our laboratory, allowed the isolation and identification of three new triterpenoid saponins (mimonosides a, b and c), three steroid saponins (3-o-beta-d-glucopyranosyl campesterol, 3-o-beta-d-glucopyranosyl stigmasterol and 3-o-beta-d-glucopyranosyl beta-sitosterol) together with lupeol, campesterol, stigmasterol and beta-sitosterol. the three new triterpenoid saponins were subjected to in vitro biological te ... | 1993 | 8510463 |
| cold stability of microtubules of mimosa pudica. | the unique property of mimosa pudica microtubules is that they are cold stable in nature. they do not dissociate at 0 degrees c unlike animal microtubules. no other protein fractions of m. pudica are responsible for the cold-resistance property of these microtubules. it seems that tubulin, itself, has an intrinsic cold resistance which makes it unique compared with animal tubulin. moreover, m. pudica microtubule makes cold-sensitive goat brain microtubule cold-resistant when used in greater than ... | 1993 | 8485459 |
| [immobilization of a sensitive plant, mimosa pudica l., by volatile anesthetics]. | the disappearance of thigmonastic mobility of a sensitive plant, mimosa pudica l., caused by volatile anesthetic agents such as methoxyflurane, chloroform, halothane, enflurane or sevoflurane revealed that the response to anesthetic agents in plants maybe similar to that in animals. in terms of reversible anesthesia, animals seem to equal plants in order of potency of anesthetics, and the minimum immobilizing concentration (mic; %) in the plant shows a good correlation with mac in the human (mic ... | 1993 | 8366560 |
| hypersensitivity to pollen allergens on the adriatic coast. | in central south croatia, i.e., the adriatic coast with the city of split at the center, year-long pollen concentrations in the air were determined for typical local plants, and the area's plant pollination calendar was established. high concentrations of parietaria officinalis pollen dominated during the year (up to 20% from april to june). pollens of pistacia lentiscus, olea europaea, pinus halepensis, juniperus oxycedrus, mimosa and cistus monspeliensis were found in lower concentrations and ... | 1994 | 7921334 |
| mimosa: a functional model of the management of medical images. | the concept of picture archiving and communication system (pacs) appeared in 1982. twelve years later most pacs prototypes still do not satisfy the medical community requirements: too much emphasis has been put on technical solutions and little effort devoted to the management of images itself. a common approach to this problem is needed more than ever to allow cost-effective systems to be developed. modelling is a way to reach this objective, and the mimosa topic within the aim/eurlpacs project ... | 1994 | 7799695 |
| medicinal plants from riau province, sumatra, indonesia. part 1: uses. | one hundred and fourteen species of flowering plants, claimed to have medicinal uses, were recorded from a previously uninvestigated area of sumatra. of the specimens, which belonged to 51 families, 50% were used to combat fever, 33% for diarrhoea and 31% for other gastrointestinal problems. external applications were often used to treat internal conditions, particularly fever. species new to the ethnomedical literature are garcinia parvifolia, scleria purpurescens, galearia filiformis, litsea e ... | 1995 | 7776664 |
| galactomannans from brazilian seeds: characterization of the oligosaccharides produced by mild acid hydrolysis. | galactomannans with man:gal ratios ranging from 1.1:1 to 3:1, obtained from the seeds of mimosa scabrella, stryphnodendron barbatiman, schizolobium parahybum and schizolobium amazonicum, were submitted to mild acid hydrolysis. the products were fractionated by gel permeation chromatography on biogel p2 yielding fractions with degrees of polymerization (dp) of 1 to 6. those with dp 2 to 6 from each species were analysed by ion-exchange high-performance liquid chromatography and characterized by 1 ... | 1995 | 7772557 |
| survival of cultured plant cells grafted into the subcutaneous tissue of rats (preliminary report). | to evaluate the survival of plant tissue in an animal environment, cultured calli from a mexican medicinal plant (mimosa tenuiflora poir.) were transplanted under sterile conditions into the subcutaneous tissue of rats. microscopic studies of grafted areas were carried out at the 30th, 60th and 120th days after transplantation. histological evidence of plant graft survival was found in specimens of all groups. during the first month of subcutaneous grafting a moderate inflammatory reaction aroun ... | 1995 | 7711454 |
| plasmalemmal, voltage-dependent ionic currents from excitable pulvinar motor cells of mimosa pudica. | plasmalemmal ionic currents from excitable motor cells of the primary pulvinus of mimosa pudica were investigated by patch-clamp techniques. in almost all of the enzymatically isolated protoplasts, a delayed rectifier potassium current was activated by depolarization, while no currents were detected upon hyperpolarization. this sustained outward current was reversibly blocked by ba and tea and serves to repolarize the membrane potential. outward single channel currents that very likely underly t ... | 1993 | 7684082 |
| triterpenoid saponins from mimosa pigra. | two novel triterpene glycosides have been isolated from mimosa pigra. the aglycone of these two compounds was identified as machaerinic acid by 1h- and 13c-nmr spectroscopy and by comparison with an authentic sample. this aglycone is substituted at position c-3 by an identical oligosaccharide chain in these glycosides, and at position c-21 by either a z/e-methoxycinnamic [1] unit or an e-cinnamic acid [2] unit. | 1995 | 7595593 |
| vibriocidal activities of some local herbs. | four of the seven tested medicinal plants exhibited antimicrobial activity against vibrio cholerae. these 7 plants are: ficus capensis, mitragyna stipulosa, entada africana, piliostigma reticulatum, terminalia avicennoides, mimosa pudica, and lannea acida. of them terminalia avicennoides showed higher antimocrobial activity than others. potentials of these herbs in the control of cholera need to be determined. | 1995 | 7594314 |
| calcium-sensitivity of the plasmalemmal delayed rectifier potassium current suggests that calcium influx in pulvinar protoplasts from mimosa pudica l. can be revealed by hyperpolarization. | isolated protoplasts from pulvinar motor cells of mimosa pudica were studied using conventional whole-cell patch clamp techniques. with internal solutions weakly buffered for ca2+ (0.2 mm egta), a rundown of the outward delayed rectifier k+ current was induced by hyperpolarizing the holding potential, and this effect was strongly promoted by high external ca2+ concentrations. this rundown could be reversed by coming back to less hyperpolarized holding potentials or by lowering the external [ca2+ ... | 1995 | 7473689 |
