Ionic currents underlying spontaneous action potentials in isolated cerebellar Purkinje neurons. (1/1232)

Acutely dissociated cell bodies of mouse Purkinje neurons spontaneously fired action potentials at approximately 50 Hz (25 degrees C). To directly measure the ionic currents underlying spontaneous activity, we voltage-clamped the cells using prerecorded spontaneous action potentials (spike trains) as voltage commands and used ionic substitution and selective blockers to isolate individual currents. The largest current flowing during the interspike interval was tetrodotoxin-sensitive sodium current (approximately -50 pA between -65 and -60 mV). Although the neurons had large voltage-dependent calcium currents, the net current blocked by cobalt substitution for calcium was outward at all times during spike trains. Thus, the electrical effect of calcium current is apparently dominated by rapidly activated calcium-dependent potassium currents. Under current clamp, all cells continued firing spontaneously (though approximately 30% more slowly) after block of T-type calcium current by mibefradil, and most cells continued to fire after block of all calcium current by cobalt substitution. Although the neurons possessed hyperpolarization-activated cation current (Ih), little current flowed during spike trains, and block by 1 mM cesium had no effect on firing frequency. The outward potassium currents underlying the repolarization of the spikes were completely blocked by 1 mM TEA. These currents deactivated quickly (<1 msec) after each spike. We conclude that the spontaneous firing of Purkinje neuron cell bodies depends mainly on tetrodotoxin-sensitive sodium current flowing between spikes. The high firing rate is promoted by large potassium currents that repolarize the cell rapidly and deactivate quickly, thus preventing strong hyperpolarization and restoring a high input resistance for subsequent depolarization.  (+info)

Electrostatic interactions during activation of coagulation factor IX via the tissue factor pathway: effect of univalent salts. (2/1232)

Interaction between the Gla-domain of coagulation proteins and negatively charged phospholipid membranes is essential for blood coagulation reactions. The interaction is calcium-dependent and mediated both by electrostatic and hydrophobic forces. This report focuses on the electrostatic component of factor IX activation via the extrinsic pathway. Effective charges during the reaction are measured by ionic titration of activity, according to the Debye-Huckel and Gouy-Chapman models. Rates of activation decrease with ionic strength independently of the type of monovalent salt used to control ionic strength. Moreover, the effect of ionic strength decreases at concentrations of charged phospholipid approaching saturation levels, indicating that membrane charges participate directly in the ionic interaction measured. The effective charge on calcium-bound factor IX during activation on phospholipid membranes is 0.95+/-0.1. Possible sites mediating contacts between the Gla-domain and membranes are selected by geometrical criteria in several metal-bound Gla-domain structures. A pocket with a solvent opening-pore of area 24-38 A2 is found in the Gla-domain of factors IX, VII, and prothrombin. The pocket contains atoms with negative partial charges, including carboxylate oxygens from Gla residues, and has a volume of 57-114 A3, sufficient to accommodate additional calcium atoms. These studies demonstrate that electrostatic forces modify the activity coefficient of factor IX during functional interactions and suggest a conserved pocket motif as the contact site between the calcium-bound Gla-domain and charged membranes.  (+info)

Modulation of slow inactivation in human cardiac Kv1.5 channels by extra- and intracellular permeant cations. (3/1232)

1. The properties and regulation of slow inactivation by intracellular and extracellular cations in the human heart K+ channel hKv1.5 have been investigated. Extensive NH2- and COOH-terminal deletions outside the central core of transmembrane domains did not affect the degree of inactivation. 2. The voltage dependence of steady-state inactivation curves of hKv1.5 channels was unchanged in Rb+ and Cs+, compared with K+, but biexponential inactivation over 10 s was reduced from approximately 100 % of peak current in Na+ to approximately 65 % in K+, approximately 50 % in Rb+ and approximately 30 % in Cs+. This occurred as a result of a decrease in both fast and slow components of inactivation, with little change in inactivation time constants. 3. Changes in extracellular cation species and concentration (5-300 mM) had only small effects on the rates of inactivation and recovery from inactivation (tau recovery approximately 1 s). Mutation of residues at a putative regulatory site at R487 in the outer pore mouth did not affect slow inactivation or recovery from inactivation of hKv1.5, although sensitivity to extracellular TEA was conferred. 4. Symmetrical reduction of both intra- and extracellular cation concentrations accelerated and augmented both components of inactivation of K+ (Kd = 34.7 mM) and Cs+ (Kd = 20.5 mM) currents. These effects could be quantitatively accounted for by unilateral reduction of intracellular K+ (K+i) (Kd = 43.4 mM) or Cs+i with constant 135 mM external ion concentrations. 5. We conclude that inactivation and recovery from inactivation in hKv1.5 were not typically C-type in nature. However, the ion species dependence of inactivation was still closely coupled to ion permeation through the pore. Intracellular ion modulatory actions were more potent than extracellular actions, although still of relatively low affinity. These results suggest the presence of ion binding sites capable of regulating inactivation located on both intracellular and extracellular sides of the pore selectivity filter.  (+info)

Gating current studies reveal both intra- and extracellular cation modulation of K+ channel deactivation. (4/1232)

1. The presence of permeant ions can modulate the rate of gating charge return in wild-type human heart K+ (hKv1.5) channels. Here we employ gating current measurements in a non-conducting mutant, W472F, of the hKv1.5 channel to investigate how different cations can modulate charge return and whether the actions can be specifically localized at the internal as well as the external mouth of the channel pore. 2. Intracellular cations were effective at accelerating charge return in the sequence Cs+ > Rb+ > K+ > Na+ > NMG+. Extracellular cations accelerated charge return with the selectivity sequence Cs+ > Rb+ > Na+ = NMG+. 3. Intracellular and extracellular cation actions were of relatively low affinity. The Kd for preventing slowing of the time constant of the off-gating current decay (tau off) was 20.2 mM for intracellular Cs+ (Cs+i) and 358 mM for extracellular Cs+ (Cs+o). 4. Both intracellular and extracellular cations can regulate the rate of charge return during deactivation of hKv1.5, but intracellular cations are more effective. We suggest that ion crystal radius is an important determinant of this action, with larger ions preventing slowing more effectively. Important parallels exist with cation-dependent modulation of slow inactivation of ionic currents in this channel. However, further experiments are required to understand the exact relationship between acceleration of charge return and the slowing of inactivation of ionic currents by cations.  (+info)

Kir2.1 encodes the inward rectifier potassium channel in rat arterial smooth muscle cells. (5/1232)

1. The molecular nature of the strong inward rectifier K+ channel in vascular smooth muscle was explored by using isolated cell RT-PCR, cDNA cloning and expression techniques. 2. RT-PCR of RNA from single smooth muscle cells of rat cerebral (basilar), coronary and mesenteric arteries revealed transcripts for Kir2.1. Transcripts for Kir2.2 and Kir2.3 were not found. 3. Quantitative PCR analysis revealed significant differences in transcript levels of Kir2.1 between the different vascular preparations (n = 3; P < 0.05). A two-fold difference was detected between Kir2.1 mRNA and beta-actin mRNA in coronary arteries when compared with relative levels measured in mesenteric and basilar preparations. 4. Kir2.1 was cloned from rat mesenteric vascular smooth muscle cells and expressed in Xenopus oocytes. Currents were strongly inwardly rectifying and selective for K+. 5. The effect of extracellular Ba2+, Ca2+, Mg2+ and Cs2+ ions on cloned Kir2.1 channels expressed in Xenopus oocytes was examined. Ba2+ and Cs+ block were steeply voltage dependent, whereas block by external Ca2+ and Mg2+ exhibited little voltage dependence. The apparent half-block constants and voltage dependences for Ba2+, Cs+, Ca2+ and Mg2+ were very similar for inward rectifier K+ currents from native cells and cloned Kir2.1 channels expressed in oocytes. 6. Molecular studies demonstrate that Kir2.1 is the only member of the Kir2 channel subfamily present in vascular arterial smooth muscle cells. Expression of cloned Kir2.1 in Xenopus oocytes resulted in inward rectifier K+ currents that strongly resemble those that are observed in native vascular arterial smooth muscle cells. We conclude that Kir2.1 encodes for inward rectifier K+ channels in arterial smooth muscle.  (+info)

Properties and functional roles of hyperpolarization-gated currents in guinea-pig retinal rods. (6/1232)

1. The inward rectification induced by membrane hyperpolarization was studied in adult guinea-pig rods by the perforated-patch-clamp technique. 2. CsCl blocked the rectification observed in both voltage- and current-clamp recordings at voltages negative to -60 mV, while BaCl2 blocked the inward relaxation observed at voltages positive to -60 mV. The current activated at -90 mV had a low selectivity between sodium and potassium and reversed at -31.0 mV. 3. These observations suggest that two inward rectifiers are present in guinea-pig rods: a hyperpolarization-activated (Ih) and a hyperpolarization-deactivated (Ikx) current. The functional roles of Ih and Ikx were evaluated by stimulating rods with currents sinusoidally modulated in time. 4. Rods behave like bandpass amplifiers, with a peak amplification of 1.5 at about 2 Hz. For hyperpolarizations that mainly gate Ikx, amplification and phase shifts are fully accounted for by a rod membrane analogue model that includes an inductance. For hyperpolarizations that also gate Ih, a harmonic distortion became apparent. 5. Bandpass filtering and amplification of rod signals, associated with Ih and Ikx gating by membrane hyperpolarization, are strategically located to extend, beyond the limits imposed by the slow phototransductive cascade, the temporal resolution of signals spreading to the rod synapse.  (+info)

Mechanisms of delta-hexachlorocyclohexane toxicity: II. Evidence for Ca2+-dependent K+-selective ionophore activity. (7/1232)

delta-Hexachlorocyclohexane (delta-HCH) interacts with cardiac ryanodine-sensitive Ca2+ channels (RyR2), accounting in part for altered Ca2+ transients and contractility (reported in companion report). Analysis of channel gating kinetics in the presence of delta-HCH also revealed a nonfluctuating membrane current that remained even after RyR2 channels were blocked. We further elucidated the nature of a direct interaction between delta-HCH and biological membranes by measuring ionic currents across planar lipid bilayers made from defined lipids lacking cellular protein using voltage-clamp. Dimethyl sulfoxide, in the presence or absence of 50 microM gamma-HCH (lindane) or delta-HCH, produced negligible steady-state current with symmetric 100 mM CsCl in the range of +/-50 mV. However, the addition of 50 microM Ca2+ to the bilayer chamber in the presence of delta-HCH induced a profound increase in ionic permeability that was not seen in the presence of gamma-HCH or dimethyl sulfoxide control. Significantly, the permeability increase 1) was proportional with increasing Ca2+ to approximately 600 microM and saturated between 1 and 2 mM Ca2+ regardless of holding potential, 2) occurred only when delta-HCH and Ca2+ were added to the same side of the membrane, and 3) was independent of the order of addition or of the side of the membrane to which delta-HCH and Ca2+ was added. The Ca2+-dependent current produced by delta-HCH was highly selective for monovalent cations (K+ >> Cs+ > Na+), with negligible conductance for Ca2+ or Cl-. In symmetric 100 mM K+, the conductance induced with 50 microM concentration each of delta-HCH and Ca2+ was 4.25 pA/mV. The results show that delta-HCH increases the ionic permeability of phospholipid membranes by two distinct Ca2+-dependent mechanisms: one mediated through RyR and the other mediated by a unique ionophore activity.  (+info)

Coordinate regulation of gonadotropin-releasing hormone neuronal firing patterns by cytosolic calcium and store depletion. (8/1232)

Elevation of cytosolic free Ca2+ concentration ([Ca2+]i) in excitable cells often acts as a negative feedback signal on firing of action potentials and the associated voltage-gated Ca2+ influx. Increased [Ca2+]i stimulates Ca2+-sensitive K+ channels (IK-Ca), and this, in turn, hyperpolarizes the cell and inhibits Ca2+ influx. However, in some cells expressing IK-Ca the elevation in [Ca2+]i by depletion of intracellular stores facilitates voltage-gated Ca2+ influx. This phenomenon was studied in hypothalamic GT1 neuronal cells during store depletion caused by activation of gonadotropin-releasing hormone (GnRH) receptors and inhibition of endoplasmic reticulum (Ca2+)ATPase with thapsigargin. GnRH induced a rapid spike increase in [Ca2+]i accompanied by transient hyperpolarization, followed by a sustained [Ca2+]i plateau during which the depolarized cells fired with higher frequency. The transient hyperpolarization was caused by the initial spike in [Ca2+]i and was mediated by apamin-sensitive IK-Ca channels, which also were operative during the subsequent depolarization phase. Agonist-induced depolarization and increased firing were independent of [Ca2+]i and were not mediated by inhibition of K+ current, but by facilitation of a voltage-insensitive, Ca2+-conducting inward current. Store depletion by thapsigargin also activated this inward depolarizing current and increased the firing frequency. Thus, the pattern of firing in GT1 neurons is regulated coordinately by apamin-sensitive SK current and store depletion-activated Ca2+ current. This dual control of pacemaker activity facilitates voltage-gated Ca2+ influx at elevated [Ca2+]i levels, but also protects cells from Ca2+ overload. This process may also provide a general mechanism for the integration of voltage-gated Ca2+ influx into receptor-controlled Ca2+ mobilization.  (+info)

The ionic compound cesium chloride adopts a cubic crystal structure bearing the same name. However, ab initio electronic structure calculations based on density functional theory methods using generalized gradient approximation functionals do not predict that cesium chloride adopts this phase. In this paper we apply semiempirical methods (density functional theory plus a pairwise dispersion correction) to account for missing van der Waals interactions within cesium chloride. The C6 and R0 dispersion parameters for cesium are established within Grimmes DFT+D2 formalism. Inclusion of the dispersion corrections is found not only to improve the quality of structures in comparison to experiment for all cesium halides, but also leads to the correct prediction of the ground-state phase under ambient conditions.. ...

The use of cesium salts as an alternative or "natural" treatment for cancer is based on the unproven theory that somehow they raise the pH inside neoplastic cells, damaging them. Advocates of cesium believe that the low incidence of cancer seen in the Hunza tribe of North Pakistan can be attributed to a diet high in cesium. These claims have never been tested. Unfortunately, the adverse effects caused by cesium have been well demonstrated both clinically and in the laboratory, and are all too real.. Cesium (atomic number 55) is an alkali metal with an ionic charge of +1. It appears on the periodic table in the same column as sodium and potassium. When ingested, it is absorbed in the small intestine and distributed throughout the body as if it were potassium. Manifestations of cesium toxicity include diarrhea, hypo-kalemia, and cardiac arrhythmia. Cesium blocks potassium re-entry into the myocardial cell during phase 3 of the action potential, delaying repolarization and prolonging the QT ...

ˈsiːziəm/ SEE-zee-əm) is the chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at (or near) room temperature.[note 2] Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium. The metal is extremely reactive and pyrophoric, reacting with water even at −116 °C (−177 °F). It is the least electronegative element that has stable isotopes, of which it has only one, caesium-133. Caesium is mined mostly from pollucite, while the radioisotopes, especially caesium-137, are extracted from waste produced by nuclear reactors.. Two German chemists, Robert Bunsen and Gustav Kirchhoff, discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for caesium have been as a "getter" in vacuum tubes and in photoelectric cells. In 1967, a specific ...

The particularities of cesium incorporation into synthetic calcium phosphates with either apatite or whitlockite-type structures were investigated using the sorption process from aqueous solution and further heating to 700 °C. The nanoparticles for sorption were prepared by wet precipitation from aqueous solutions at a fixed molar ratio of Ca/P = 1.67 and two different ratios of CO32−/PO43− (0 or 1). The obtained substituted calcium phosphates and corresponding samples after the sorption of cesium from solutions with different molar concentrations (c(Cs+) = 0.05, 0.1 and 0.25 mol L−1) were characterized by powder X-ray diffraction, FTIR spectroscopy, scanning electron microscopy and elemental analysis. Based on the combination of X-ray diffraction and elemental analyses data for the powders after sorption, the cesium incorporated in the apatite- or whitlockite-type structures and its amount increased with its concentration in the initial solution. For sodium-containing calcium phosphate even

Here, we demonstrate the successful synthesis of brightly emitting colloidal cesium lead halide (CsPbX3, X = Cl, Br, I) nanowires (NWs) with uniform diameters and tunable compositions. By using highly monodisperse CsPbBr3 NWs as templates, the NW composition can be independently controlled through anion-exchange reactions. CsPbX3 alloy NWs with a wide range of alloy compositions can be achieved with well-preserved morphology and crystal structure. The NWs are highly luminescent with photoluminescence quantum yields (PLQY) ranging from 20% to 80%. The bright photoluminescence can be tuned over nearly the entire visible spectrum. The high PLQYs together with charge transport measurements exemplify the efficient alloying of the anionic sublattice in a one-dimensional CsPbX3 system. The wires increased functionality in the form of fast photoresponse rates and the low defect density suggest CsPbX3 NWs as prospective materials for optoelectronic applications.

Semi-conservative replication of DNA was proved by the work of Mathew Meselson and Franklin Stahl (1958). They grew Escherichia coli for many generations in a medium having heavy isotope of nitrogen, in the form of 15NH4Cl, till the bacterial DNA became com-pletely labelled with heavy isotope.. The labelled bacteria were then shifted to fresh medium hav-ing normal or 14N nitrogen. Samples were taken for each generation (one generation takes 20 minutes as E. coli divides in 20 minutes) and the DNA was tested for the heavy isotope of nitrogen through density gradient centrifugation using caesium chloride. Caesium chloride is highly water soluble heavy salt.. When spun in centrifuge at high speed (say 50,000 revolutions per minute) the salt forms a density gradient with heaviest most concentrated region at the bottom and successively less concentrated lighter one towards the surface. When DNA is mixed with caesium chloride it will settle down at a particular height in centrifugation, heavier ...

Co-authors of the paper include Justin Brown, David Butts, Joseph Kinast, and Richard Stoner of Draper Laboratory.. A shift in Time. The team came up with the new atomic timekeeping approach by making several "tweaks" to the standard method.. The most accurate atomic clocks today use cesium atoms as a reference. Like all atoms, the cesium atom has a signature frequency, or resonance, at which it oscillates. Since the 1960s, one second has been defined as 9,192,631,770 oscillations of a cesium atom between two energy levels. To measure this frequency, fountain clocks toss small clouds of slow-moving cesium atoms a few feet high, much like a pulsed fountain, and measure their oscillations as they pass up, and then down, through a microwave beam.. Instead of a microwave beam, the group chose to probe the atoms oscillations using laser beams, which are easier to control spatially and require less space -- a quality that help in shrinking atomic clock apparatuses. While some atomic clocks also ...

Each of these changes was made because the precision with which we could make the measurements became greater than the precision with which we could realize, or make use of, the previous definition. Today, we choose definitions based on fundamental physical constants and atomic properties because they provide more stable and universally available standards. They may also generally be measured relatively easily and with high precision. Each change of definition is chosen to maintain unchanged the previous value of the standard, to the accuracy with which it had previously been known.. It is important to note that the effect of each new definition is to set a fixed value for some relevant constant. Thus, the present definition of the second sets the value of the frequency of the caesium transition to be exactly 9,192,631,770 Hertz, and the present definition of the metre sets the speed of light to be exactly 299,792,458 metres per second. The 1793 definition of the metre set the distance from the ...
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a UC Berkeley team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.

However, none of the diverse methods of rectification provides the desired safety or assurance.

Caesium auride (CsAu) is an ionic compound containing the unusual Au− ion first discovered in 1978 in the laboratory of Joseph Lagowski. It is obtained by heating a stoichiometric mixture of caesium and gold; the two metallic-yellow liquids react to give a clear product. The solution in liquid ammonia is brown, and the solid is yellow (the colour of both metals making up the compound); the ammonium adduct is dark blue. Despite being a compound of two metals, CsAu lacks metallic properties since the free electrons in both metals are used up, as in all ionic compounds. The compound reacts violently with water, yielding caesium hydroxide, metallic gold, and hydrogen gas; in liquid ammonia it can be reacted with a caesium-specific ion exchange resin to produce tetramethylammonium auride.

A simple and robust technique for the extraction of DNA under tropical field conditions is described. It requires minimal equipment and is based on lysing cells in whole blood and precipitating the nuclei containing the DNA by centrifugation. The DNA solution can be stored in guanidinium buffer for many months without being refrigerated. Further purification of the DNA can then be carried out in a laboratory with facilities for ultracentrifugation by banding the DNA through cesium chloride. This method yields DNA of sufficient quality and purity for Southern blotting and probing and alleviates the need to transport whole blood between different countries and laboratories.. ...
2. Time is conceptualizable as the use of durations called time-intervals (TIs) as units of temporal measurement for the measurement of the occurrences of events. Humans and machines who/which need to record or coordinate events use time via TIs to measure the time at which events occurred in the past and the present and to predict/coordinate the occurrences of events of events in the future. The essence of time is the time-interval (TI), the unit of measurement of time, which is a duration, most often modeled from the duration of a regularly recurring periodic or cyclic motion, such as the duration of the yearly orbit of the Earth about the Sun, or the regularly recurring oscillations of a cesium atom. Once chosen, a TI becomes an abstraction which can be manifested/made real/actualized/realized in machines including clocks. A TI as a unit of measurement of the occurrences of events sets the rate of operation (RoO) for machines and the rate of ticking (RoT) for clocks, and describes the ...
The invention of the hamburger was a way of homogenising cows. Take whatever you want from any number of animals (but one hopes cows), grind it all up and suddenly you now have a consistent and uniform beef unit: the hamburger "patty". In this same manner, humanity took time as it was once experienced and converted it into seconds, minutes and hours. A second is basically a "time patty", or "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the Caesium 133 atom".1 Romantic ...

atented Oct. 28, 1952 PURIFICATION .OF BOROHYDRIDES F ALKALI METALS Thomas R. P. Gibb, Jr., Marblehead, Mass as signor to .Metal ,Hydrides Incorporated, Beverly, Mass., a corporation of Massachusetts NoDrawing. Application November 14, 1949, Serial ,No. 127,239 4 Claims. 1 This invention relates to the preparation of sodium borohydride and borohydrides of other alkali metals and more especially to the purification of such borohydrides. Borohydrides of the alkali metals can be produced by reacting an alkyl borate with an alkali metal hydride. The principal products of the reaction are the borohydride of the alkali metal and the alkoxide of the alkali metal. vThus, if methyl borate isbrought in contact with sodium hydride while heated to a temperature of about 245 C. to 265 C. a mixture of sodiumborohydride and sodium methoxide is produced. Thereaction may be illustrated by the following equation: The sodium borohydride may be separated from the sodium methoxide by dissolving with ...

In all of them the alkali metal cation is placed away from the Ti-C,sub,α1,/sub,-C,sub,α2,/sub, plane at the distance: Li,sup,+,/sup, 0.511 Å, Na,sup,+,/sup, 1.023 Å and Cs,sup,+,/sup, 0.521 Å. The reason for the deviation of Li,sup,+,/sup, in ,strong,2a,/strong, is the asymmetrical orientation of the THF ligands in the [Li(THF),sub,2,/sub,],sup,+,/sup, cation with respect to the Ti-C,sub,α1,/sub,-C,sub,α2,/sub, plane, which seems to release the steric congestion between the THF ligands and the ...
Summary: Caesium accumulation by Chlorella salina, from buffer (pH 8.0) supplemented with 50 μM-CsCl and 137Cs, continued for approximately 15 h and displayed first-order kinetics, indicating a single rate-limiting transport process. Efflux of Cs+ from Cs+-loaded cells occurred in two distinct phases: a rapid initial loss, representing approximately 11% of total cellular Cs+, corresponded to release from the cell surface, whereas a second, slower, phase of efflux corresponded to loss from the cytoplasm and vacuole. Analysis of subcellular Cs+ compartmentation revealed that most Cs+ was accumulated into the vacuole of C. salina, with lesser amounts being associated with the cell surface or located in the cytoplasm. Uptake of Cs+ into the vacuole was correlated with a stoichiometric exchange for K+. However, no loss of K+ from the cell surface or cytoplasm was evident nor was Cs+ or K+ associated with insoluble intracellular components. Calculated values for the Cs+ flux across the vacuolar membrane were
Radioactive cesium of up to 30.8 becquerels per kilogram has been found in baby formula manufactured and sold by Meiji Co., sources familiar with the matter said Tuesday, citing a sampling by the major food company.
In the new study, Yu, Kim and their colleagues looked for VNO potassium channels, which admit positively charged potassium ions. They began by setting up whole-cell patch clamp tests, in which tiny electrodes measure the net flow of charged ions through the membranes of neurons in a slice of mouse VNO tissue. To determine the contribution of potassium ions to these currents, they replaced the potassium ions in the neurons with chemically similar cesium ions, which cannot get through potassium channels. When these potassium-depleted VNO neurons were exposed to pheromone-containing mouse urine, the usual net inward flow of positive charge was significantly greater than it had been when the neurons contained potassium.. That and other experiments with the VNO tissue slices suggested that potassium ions normally flow out of VNO neurons through potassium channels when a VNO receptor is activated. This was not completely unexpected; neurons typically have a greater concentration of potassium ions ...
A family of novel and unique synthetic alkali metal alumino-silicates (SAMS) are produced by the hydrothermal reaction between kaolin and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition of xM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 O where x is the number of moles of alkali metal oxides and is an integer from 0.01 to 2.0, M is the alkali metal, y is the number of moles of SiO2 in the unique SAMS compositions and is an integer greater than 2.0, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.
Human activities lead to increasing concentration of the stable elements cesium (Cs) and strontium (Sr) and their radioactive isotopes in the food chain, where plants play an important part. Here we investigated Plantago major under the influence of long-term exposure to stable Cs and Sr. The plants were cultivated hydroponically in different concentrations of cesium sulfate (between 0.002 and 20â ¯mM) and strontium nitrate (between 0.001 and 100â ¯mM). Uptake of Cs and Sr into leaves was analyzed from extracts by inductively coupled plasma mass spectrometry (ICP-MS). It was increased with increasing external Cs and Sr concentrations. However, the efficiency of Cs and Sr transfer from solution to plants was higher for low external concentrations. Highest transfer factors were 6.78 for Cs and 71.13 for Sr. Accumulation of Sr was accompanied by a slight decrease of potassium (K) and calcium (Ca) in leaves, whereas the presence of Cs in the medium affected only uptake of K. The toxic effects of ...

Japan may have buried its twenty thousand dead-at least those who did not vanish under the debris or the waves-but thousands of people continue to await the return of their livelihoods, lost amid the wreckage and the nuclear nightmare. They hope for the day when they might go back to their homes and work to rebuild their lives. Most do not know, and have not been informed by the government or Tokyo Electric, that they can never return to the hometowns where contamination will remain lethal far beyond their life spans.. The power company and the government, joined at the hip, lecture Japanese that we have received the benefit of nuclear power generation and, because of such power, we enjoyed postwar prosperity. Hence we should not complain. Did ordinary people have any choice in deciding that Japan would develop nuclear power? No, other than the residents of small, remote communities on the shoreline who were wooed by promises of huge tax benefits, jobs for local people, and new infrastructure ...

Rydberg matter is an exotic phase of matter formed by Rydberg atoms; it was predicted around 1980 by É. A. Manykin, M. I. Ozhovan and P. P. Poluéktov. It has been formed from various elements like caesium, potassium, hydrogen and nitrogen; studies have been conducted on theoretical possibilities like sodium, beryllium, magnesium and calcium. It has been suggested to be a material that diffuse interstellar bands may arise from. Circular Rydberg states, where the outermost electron is found in a planar circular orbit, are the most long-lived, with lifetimes of up to several hours, and are the most common. Rydberg matter consists of usually hexagonal planar clusters; these cannot be very big because of the retardation effect caused by the finite velocity of the speed of light. Hence, they are not gases or plasmas; nor are they solids or liquids; they are most similar to dusty plasmas with small clusters in a gas. Though Rydberg matter can be studied in the laboratory by laser probing, the largest ...

Radioactive cesium (137Cs) has inevitably become a human concern due to exposure from nuclear power plants and nuclear accident releases. Many efforts have been focused on removing cesium and the remediation of the contaminated environment. In this study, we elucidated the ability of Prussian blue-coated magnetic nanoparticles to eliminate cesium from radioactive contaminated waste. Thus, the obtained Prussian blue-coated magnetic nanoparticles were then characterized and examined for their physical and radioactive cesium adsorption properties. This Prussian blue-coated magnetic nanoparticle-based cesium magnetic sorbent can offer great potential for use in in situ remediation.
The method used for the isolation of large scale cosmid and plasmid DNA is an unpublished modification (16) of an alkaline lysis procedure (17,18) followed by equilibrium ultracentrifugation in cesium chloride-ethidium bromide gradients (1). Briefly, cells containing the desired plasmid or cosmid are harvested by centrifugation, incubated in a lysozyme buffer, and treated with alkaline detergent. Detergent solubilized proteins and membranes are precipitated with sodium acetate, and the lysate is cleared first by filtration of precipitate through cheesecloth and then by centrifugation. The DNA-containing supernatant is transferred to a new tube, and the plasmid or cosmid DNA is precipitated by the addition of polyethylene glycol and collected by centrifugation. The DNA pellet is resuspended in a buffer containing cesium chloride and ethidium bromide, which is loaded into polyallomer tubes and subjected to ultracentrifugation overnight. The ethidium bromide stained plasmid or cosmid DNA bands, ...
When explosive emission cathodes are used in higher power 100 MW devices, microwave pulse shortening occurs because of motion of the cathode plasma at speeds 1 to 5 x 10exp 6 cmsec. This limited duration in turn can limit present-day high power microwave HPM sources to a few hundred joules. The introduction of cathodes made from Cesium Iodide-coated CsI carbon fiber has shown plasma speeds reduced by factors of a few from uncoated carbon fiber, but previous work was at low diode fields of a few 10s of kVcm. We have demonstrated reduced CsI plasma speed for macroscopic electric fields of 265 kVcm, sufficient for the diodes of GW microwave sources. Carbon fiber coated with CsI in saturated solution gives plasma speeds at these high electric fields of -0.6 x 10exp 6 cmsec, about three times less than the bare carbon fiber. The apparatus had oil-free high vacuum conditions and the cathode was baked both before assembly at atmospheric pressure and in vacuum after assembly, to temperatures of 600 deg C. A
Probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium or cesium.
