European interlaboratory comparison of breath 13CO2 analysis. (1/522)

The BIOMED I programme Stable Isotopes in Gastroenterology and Nutrition (SIGN) has focused upon evaluation and standardisation of stable isotope breath tests using 13C labelled substrates. The programme dealt with comparison of 13C substrates, test meals, test conditions, analysis techniques, and calculation procedures. Analytical techniques applied for 13CO2 analysis were evaluated by taking an inventory of instrumentation, calibration protocols, and analysis procedures. Two ring tests were initiated measuring 13C abundances of carbonate materials. Evaluating the data it was found that seven different models of isotope ratio mass spectrometers (IRMS) were used by the participants applying both the dual inlet system and the continuous flow configuration. Eight different brands of certified 13C reference materials were used with a 13C abundance varying from delta 13CPDB -37.2 to +2.0/1000. CO2 was liberated from certified material by three techniques and different working standards were used varying from -47.4 to +0.4/1000 in their delta 13CPDB value. The standard deviations (SDs) found for all measurements by all participants were 0.25/1000 and 0.50/1000 for two carbonates used in the ring tests. The individual variation for the single participants varied from 0.02 /1000 (dual inlet system) to 0.14/1000 (continuous flow system). The measurement of the difference between two carbonates showed a SD of 0.33/1000 calculated for all participants. Internal precision of IRMS as indicated by the specifications of the different instrument suppliers is < 0.3/1000 for continuous flow systems. In this respect it can be concluded that all participants are working well within the instrument specifications even including sample preparation. Increased overall interlaboratory variation is therefore likely to be due to non-instrumental conditions. It is possible that consistent differences in sample handling leading to isotope fractionation are the causes for interlaboratory variation. Breath analysis does not require sample preparation. As such, interlaboratory variation will be less than observed for the carbonate samples and within the range indicated as internal precision for continuous flow instruments. From this it is concluded that pure analytical interlaboratory variation is acceptable despite the many differences in instrumentation and analytical protocols. Coordinated metabolic studies appear possible, in which different European laboratories perform 13CO2 analysis. Evaluation of compatibility of the analytical systems remains advisable, however.  (+info)

Direct EPR detection of the carbonate radical anion produced from peroxynitrite and carbon dioxide. (2/522)

The biological effects of peroxynitrite have been recently considered to be largely dependent on its reaction with carbon dioxide, which is present in high concentrations in intra- and extracellular compartments. Peroxynitrite anion (ONOO-) reacts rapidly with carbon dioxide, forming an adduct, nitrosoperoxocarboxylate (ONOOCO2-), whose decomposition has been proposed to produce reactive intermediates such as the carbonate radical (CO-3). Here, by the use of rapid mixing continuous flow electron paramagnetic resonance (EPR), we directly detected the carbonate radical in flow mixtures of peroxynitrite with bicarbonate-carbon dioxide over the pH range of 6-9. The radical was unambiguously identified by its EPR parameters (g = 2.0113; line width = 5.5 G) and by experiments with bicarbonate labeled with 13C. In this case, the singlet EPR signal obtained with 12C bicarbonate splits into the expected doublet because of 13C (a(13C)= 11.7 G). The singlet spectrum of the unlabeled radical was invariant between pH 6 and 9, confirming that in this pH range the detected radical is the carbonate radical anion (CO-3). Importantly, in addition to contributing to the understanding of nitrosoperoxocarboxylate decomposition pathways, this is the first report unambiguously demonstrating the formation of the carbonate radical anion at physiological pHs by direct EPR spectroscopy.  (+info)

Islet cell membrane antigens activate diabetogenic CD4+ T-cells in the BB/Wor rat. (3/522)

Type 1 diabetes is a major histocompatibility complex (MHC) class II-associated autoimmune disease mediated by beta-cell-specific T-cells and characterized by circulating autoantibodies to beta-cell molecules. In the BB/Wor diabetes-prone (DP) rat, type 1 diabetes develops spontaneously with an incidence of >90%. BB diabetes can be adoptively transferred to naive syngeneic or MHC class II-compatible rats with islet cell-activated T-cell lines derived from diabetic BB/Wor rats. However, the target beta-cell autoantigen(s) in BB diabetes has not yet been defined. BB rat T-cell lines activated in vitro with antigen-presenting cells (APC) and BB islet cell crude membranes (CM), but not islet cell cytosol, adoptively transfer diabetes into young DP recipients. To determine if the target autoantigen is an integral or peripheral membrane protein, islet cell CM were treated with 0.5 mol/l KCl or 0.2 mol/l Na2CO3 (pH 11). Both treatments selectively extract peripheral proteins from the cell membrane without affecting the disposition of integral (transmembrane) proteins. T-cell lines activated in vitro with APC and 0.5 mol/l KCl, or pH 11 (0.2 mol/l Na2CO3)-treated islet cell CM, transferred diabetes into young DP rats. Conversely, T-cell lines activated in vitro with APC and the supernatant of 0.5 mol/l KCl-treated CM (containing extracted peripheral proteins), did not adoptively transfer diabetes. After activation in vitro with islet cell membrane antigens, the diabetes-inducing cell lines were comprised of both CD4+ CD8- T-cells and 10-30% B-cells. We conclude that a major CD4+ T-cell target autoantigen in BB diabetes is a membrane-associated beta-cell molecule with the characteristics of an integral beta-cell membrane protein. The identification of this MHC class II-restricted beta-cell target molecule will allow the design of antigen-specific intervention protocols to prevent the onset of type 1 diabetes in genetically susceptible individuals.  (+info)

A 60 kDa plasma membrane protein changes its localization to autophagosome and autolysosome membranes during induction of autophagy in rat hepatoma cell line, H-4-II-E cells. (4/522)

We previously reported the preparation and characterization of an antibody against membrane fraction of autolysosomes from rat liver (J. Histochem. Cytochem. 38, 1571-1581, 1990). Immunoblot analyses of total membrane fraction of a rat hepatoma cell line, H-4-II-E cells by this antibody suggested that H-4-II-E cells expressed several autolysosomal proteins, including a protein with apparent molecular weight of 60 kDa. It was suggested that this 60 kDa protein was a peripheral membrane protein, because it was eluted from the membrane by sodium carbonate treatment. We prepared an antibody against this 60 kDa protein by affinity purification method, and examined its behavior during induction of autophagy. Autophagy was induced by transferring the cells from Dulbecco's modified Eagle medium (DMEM) containing 12% fetal calf serum into Hanks' balance salt solution. In DMEM, the 60 kDa protein showed diffused immunofluorescence pattern, and immunoelectron microscopy suggested that this protein was located on the extracellular side of the plasma membrane. After inducing autophagy, the immunofluorescence configuration of the 60 kDa protein changed from the diffused pattern to a granulous one. Immunoelectron microscopy showed that the 60 kDa protein was localized on the luminal side of the limiting membrane of autolysosomes and endosomes. In the presence of bafilomycin A1 which prevents fusion between autophagosomes and lysosomes, the 60 kDa protein was localized on the limiting membrane of the autophagosomes and endosomes. These results suggest that the 60 kDa protein is transported from the plasma membrane to the autophagosome membrane through the endosomes.  (+info)

Degradation of polycarbonate by a polyester-degrading strain, Amycolatopsis sp. strain HT-6. (5/522)

Amycolatopsis sp. strain HT-6, a poly(tetramethylene succinate) (PTMS)-degrading actinomycete, was observed to degrade poly(tetramethylene carbonate) (PTMC). In a liquid culture with 150 mg of PTMC film, 59% degradation was achieved, but with a low yield of cell growth. On the other hand, PTMS copolymerized with a small amount of PTMC, forming a copolyester carbonate (PEC) that was completely and rapidly degraded with a high yield of cell growth.  (+info)

T-1095, an inhibitor of renal Na+-glucose cotransporters, may provide a novel approach to treating diabetes. (6/522)

T-1095A and T-1095 are synthetic agents derived from phlorizin, a specific inhibitor of Na+-glucose cotransporters (SGLTs). Unlike phlorizin, T-1095 is absorbed into the circulation via oral administration, is metabolized to the active form, T-1095A, and suppresses the activity of SGLTs in the kidney. Orally administered T-1095 increases urinary glucose excretion in diabetic animals, thereby decreasing blood glucose levels. Indeed, the postprandial hyperglycemia after a meal load was shown to be suppressed by this compound in streptozotocin (STZ)-induced diabetic rats. With long-term T-1095 treatment, both blood glucose and HbA1c levels were reduced in STZ-induced diabetic rats and yellow KK mice. In addition, there was amelioration of abnormal carbohydrate metabolism, i.e., hyperinsulinemia and hypertriglyceridemia, and of the development of microalbuminuria, in yellow KK mice. Thus, T-1095 may be a useful antidiabetic drug, providing a novel therapeutic approach for diabetes.  (+info)

The age of the carbonates in martian meteorite ALH84001. (7/522)

The age of secondary carbonate mineralization in the martian meteorite ALH84001 was determined to be 3.90 +/- 0.04 billion years by rubidium-strontium (Rb-Sr) dating and 4.04 +/- 0.10 billion years by lead-lead (Pb-Pb) dating. The Rb-Sr and Pb-Pb isochrons are defined by leachates of a mixture of high-graded carbonate (visually estimated as approximately 5 percent), whitlockite (trace), and orthopyroxene (approximately 95 percent). The carbonate formation age is contemporaneous with a period in martian history when the surface is thought to have had flowing water, but also was undergoing heavy bombardment by meteorites. Therefore, this age does not distinguish between aqueous and impact origins for the carbonates.  (+info)

Antibodies against pex14p block ATP-independent binding of matrix proteins to peroxisomes in vitro. (8/522)

The membrane protein Pex14p is a key component of the protein import machinery of peroxisomes. Antibodies raised against human Pex14p recognise a 66 kDa protein in sunflower glyoxysomes (HaPex14p) and immunoprecipitate in vitro-translated Arabidopsis Pex14p (AtPex14p). These antibodies inhibit the ATP-independent binding to sunflower peroxisome membranes of peroxisome targeting signal type (PTS) 1- and PTS2-targeted matrix proteins, but not an integral membrane protein. These results suggest that Pex14p functions before the ATP-dependent step of peroxisome assembly.  (+info)

Three parameters such as temperature, reaction time, and Na2CO3 concentration were identified as experimental factors, and yield was selected as a response parameter. The experimental factors were optimised employing Response Surface Methodology (RSM). Maximum yield of 29.6% was obtained at reaction time of 20.41 min, Na2CO3 of 0.51% at 90 °C. To overcome this limited lactulose yield, due to the conversion of lactulose to galactose, fed batch system was applied using dried cheese whey as lactose source. By this system, limit was broken, and 15.8 g/L of lactulose is produced in hour.

  • Magnesium carbonate crystallizes in the calcite structure wherein Mg 2+ is surrounded by six oxygen atoms. (
  • Calcium carbonate has two major crystalline forms - two different geometric arrangements of the calcium ions and carbonate ions that make up the compound - aragonite and calcite. (
  • In its pure form, calcium carbonate is a white powder with a specific gravity of 2.71 in the calcite form or 2.93 in the aragonite form. (
  • Evidence for significant quantities of carbonate deposits on the surface began to increase in 2008 when the Thermal and Evolved Gas Analyzer (TEGA) and WCL experiments on the 2007 Phoenix Mars lander found between 3-5wt% calcite (CaCO3) and an alkaline soil. (
  • Calcium carbonate exists in nature as mineral aragonite and calcite (as in limestone, chalk and marble). (
  • The calcite in carbonate minerals is a unique mineral as its cleavage takes three distinct directions and has double refraction. (
  • It had been known that calcium carbonate is initially present in amorphous, i.e., disordered form and only later takes on the regular structure of calcite. (
  • Other examples of carbonates include calcite, dolomite, and marble. (
  • Sedimentary rocks containing calcite and other carbonates are plentiful in the earth. (
  • Calcium carbonate deposits can be formed in sea-water when calcium ions dissolved from other minerals react with dissolved carbon dioxide ( carbonic acid , H 2 CO 3 ). (
  • Carbonates are salts of carbonic acid. (
  • 1) The metallic carbonates are the salts of carbonic acid, H 2 CO 3 . (
  • 2) The organic carbonates are the esters of carbonic acid, H 2 CO 3 , and of the unknown ortho-carbonic acid, C(OH) 4 . (
  • Anhydrous sodium carbonate is the waterless crystalline form of sodium carbonate, the sodium salt of carbonic acid. (
  • The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group O=C(O-) 2 . (
  • It is the conjugate base of the hydrogen carbonate (bicarbonate) ion, HCO 3 − , which is the conjugate base of H 2 CO 3 , carbonic acid. (
  • In aqueous solution , carbonate, bicarbonate, carbon dioxide, and carbonic acid exist together in a dynamic equilibrium . (
  • When the partial pressure of CO 2 is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate (carbonate, bicarbonate, carbon dioxide, and carbonic acid) shifts until the concentration of CO 2 in the solution is equal to the solubility of CO 2 at that temperature and pressure. (
  • Potassium carbonate, K 2 CO 3 (s), (IRRITANT) - see CLEAPSS Hazcard. (
  • When heated with ammonia it yields guanidine, and on boiling with alcoholic potash it yields potassium carbonate. (
  • Potassium carbonate is the inorganic compound with the formula K 2 CO 3 . (
  • Potassium carbonate is mainly used in the production of soap and glass . (
  • Potassium carbonate is the primary component of potash and the more refined pearl ash or salts of tartar. (
  • German gingerbread recipes often use potassium carbonate as a baking agent, although in combination with hartshorn . (
  • The process of adding potassium carbonate to cocoa powder is usually called "Dutching" (and the products referred to as Dutch-processed cocoa powder), as the process was first developed in 1828 by Coenrad Johannes van Houten , a Dutchman. (
  • In this study, we focused on the regeneration temperature of carbon aerogel-potassium carbonate (CA-KC) nanocomposites, where KC nanocrystals were formed in the mesopores of the CAs. (
  • Sodium carbonate ("soda" or "natron") and potassium carbonate ("potash") have been used since antiquity for cleaning and preservation, as well as for the manufacture of glass . (
  • Potassium Carbonate (also called Salt of Tartar or Pearl Ash) is an inorganic salt that appears as a white, odorless powder. (
  • Notify me when Potassium Carbonate is in stock. (
  • The joint venture is one of the world's largest producers of potassium carbonate and potassium bicarbonate and sells its products in the international market through the International Sales Department of OxyChem. (
  • Potassium carbonate is an inorganic compound important to many industries and its use is as old as recorded history. (
  • Centuries ago in Pompeii potassium carbonate was leached from ashes and mixed with slaked lime for soap making. (
  • Today, potassium hydroxide (caustic potash or KOH), produced through the electrolysis of potassium chloride brine, is reacted with carbon dioxide to form potassium carbonate. (
  • Anhydrous potassium carbonate can be purchased in 50-pound bags, 25-kilogram bags, drums, super sacks, bulk trucks and bulk rail car quantities. (
  • Liquid potassium carbonate is sold in drums, totes, tank trucks and tank cars. (
  • Anhydrous potassium carbonate is also sold as a milled product in quantities of 50-pound bag-in-box, drums, or super sacks. (
  • Students should find that sodium and potassium carbonates give no carbon dioxide or any other sign that decomposition has taken place, even after prolonged heating. (
  • They manufactured shells and skeletons of calcium carbonate using the calcium ions and carbon dioxide in the oceans, just as clams, oysters, and corals do today. (
  • At that time, carbonates would have formed from water and the carbon dioxide-rich atmosphere. (
