Modification of chitosan to improve its hypocholesterolemic capacity. (1/88)

Cholestyramine is the most widely used bile acid sequestrant in the treatment of hypercholesterolemia. However, cholestyramine has unpleasant side effects as a consequence of its hydrophobic backbone. Therefore, high-capacity bile acid sequestering biopolymers with cationic chitosan derivatives were developed, because electrostatic interactions are important for binding with bile acid anions. Dialkylaminoalkylation and reductive amination of chitosan were done to add dialkylaminoalkyl and an additional free amino group at a hydroxyl site in the chitosan backbone respectively and the amino-derivatized chitosan derivatives were quaternized with methyl iodide to produce a cationic polyelectrolyte. The in vitro bile acid binding capacity of the chitosan derivatives in aqueous NaCl was measured by reversed-phase HPLC. The binding capacities of sodium glycocholate (a major bile acid) to chitosan, DEAE-chitosan, quaternized DEAE-chitosan, and cholestyramine were 1.42, 3.12, 4.06, and 2.78 mmol/g resin, respectively. With quaternized DEAE-chitosan, the bile acid binding capacity increased approximately 50% over that of cholestyramine. The bile acid binding capacity of dialkylaminoalkyl chitosan derivatives increased with the number of carbons in the alkyl groups, indicating that hydrophobic interaction is a secondary factor for the sequestration of bile acids.  (+info)

Combined biochemical and electron microscopic analyses reveal the architecture of the mammalian U2 snRNP. (2/88)

The 17S U2 small nuclear ribonucleoprotein particle (snRNP) represents the active form of U2 snRNP that binds to the pre-mRNA during spliceosome assembly. This particle forms by sequential interactions of splicing factors SF3b and SF3a with the 12S U2 snRNP. We have purified SF3b and the 15S U2 snRNP, an intermediate in the assembly pathway, from HeLa cell nuclear extracts and show that SF3b consists of four subunits of 49, 130, 145, and 155 kD. Biochemical analysis indicates that both SF3b and the 12S U2 snRNP are required for the incorporation of SF3a into the 17S U2 snRNP. Nuclease protection studies demonstrate interactions of SF3b with the 5' half of U2 small nuclear RNA, whereas SF3a associates with the 3' portion of the U2 snRNP and possibly also interacts with SF3b. Electron microscopy of the 15S U2 snRNP shows that it consists of two domains in which the characteristic features of isolated SF3b and the 12S U2 snRNP are conserved. Comparison to the two-domain structure of the 17S U2 snRNP corroborates the biochemical results in that binding of SF3a contributes to an increase in size of the 12S U2 domain and possibly induces a structural change in the SF3b domain.  (+info)

Separation of nucleotide oligomers by unitary anion-exchange. (3/88)

This paper is the first report on the retention behavior of synthetic oligonucleotides and nucleotide oligomers on a continuous-bedmatrix, strong-anion-exchange column. The separation mechanism is predominantly an anion-exchange process, but hydrophobic interaction plays a role as well. The separation is based on the chain length of the oligonucleotide. Both the addition of organic mobile phase modifiers and changes in column temperature affect the retention of oligomers significantly. A volatile buffer system (e.g., triethylamine acetate) could be employed to purify oligonucleotides, and no desalting procedure would be required after the column separation step. The recoveries from the separation are 70% or higher. The maximum loading capacity of an analytical column (35 x 7-mm i.d.) was found to be more than 366 micrograms.  (+info)

Quantitation of intracellular triphosphate of emtricitabine in peripheral blood mononuclear cells from human immunodeficiency virus-infected patients. (4/88)

An analytical methodology combining solid-phase extraction (SPE) and high-performance liquid chromatography (HPLC) was developed to quantitate the intracellular active 5'-triphosphate (TP) of beta-L-2',3'-dideoxy-5-fluoro-3'-thiacytidine (emtricitabine) (FTC) in human peripheral blood mononuclear cells (PBMCs). The FTC nucleotides, including 5'-mono-, di-, and triphosphates, were successively resolved on an anion-exchange SPE cartridge by applying a gradient of potassium chloride. The FTC-TP was subsequently digested to release the parent nucleoside that was finally analyzed by HPLC with UV detection (HPLC-UV). Validation of the methodology was performed by using PBMCs from healthy donors exposed to an isotopic solution of [(3)H]FTC with known specific activity, leading to the formation of intracellular FTC-TP that was quantitated by an anion-exchange HPLC method with radioactive detection. These levels of FTC-TP served as reference values and were used to validate the data obtained by HPLC-UV. The assay had a limit of quantitation of 4. 0 pmol of FTC-TP (amount on column from approximately 10(7) cells). Intra-assay precision (coefficient of variation percentage of repeated measurement) and accuracy (percentage deviation of the nominal reference value), estimated by using quality control samples at 16.2, 60.7, and 121.5 pmol, ranged from 1.3 to 3.3% and -1.0 to 4. 8%, respectively. Interassay precision and accuracy varied from 3.0 to 10.2% and from 2.5 to 6.7%, respectively. This methodology was successfully applied to the determination of FTC-TP in PBMCs of patients infected with human immunodeficiency virus after oral administration of various dosing regimens of FTC monotherapy.  (+info)

The use of histological techniques for the demonstration of ion exchange resins. (5/88)

AIM: To establish the staining characteristics of certain ion exchange resins in histological material, with a view to enabling confident differential identification. METHODS: Various histological staining procedures were applied to selected pathological material and prepared agar blocks containing the cation exchange resin calcium polystyrene sulphonate and the anion exchange resin cholestyramine. RESULTS: Calcium polystyrene sulphonate uniquely stained strongly by a direct Schiff's reagent procedure without any preoxidation and by the Ziehl-Neelsen method. Cholestyramine was negative by the former method but stained strongly with a standard Congo red technique. CONCLUSIONS: These staining results are consistent with the known structure and properties of polystyrene sulphonate and cholestyramine resins. Polystyrene sulphonate resins have the virtually pathognomonic feature of direct Schiff positivity, while morphology, location, and strong non-birefringent Congo red positivity facilitate the identification of cholestyramine. It is possible that the intrinsic staining characteristics of cholestyramine may be lost once it has bound to its target.  (+info)

An analytical system for rapid separation of tissue nucleotides at low pressures on conventional anion exchangers. (6/88)

An analytical anion-exchange procedure has been developed for the rapid separation of acid-soluble nucleotides (the so-called "free" or tissue nucleotides). It permits assay at low pressures (275-415 kPa; 40-60 psi) in less than 1 h on 10-cm columns of Aminex resins (conventional styrene-type anion exchangers) with alkaline citrate solutions as the eluent. Separation variables have been investigated, to determine optimum conditions for the routine analysis of samples containing tissue nucleotides. Also described here is a simple solvent-extraction procedure for removing HCIO4 or CCI3CO2H quantitatively from cell extracts that contain acid-soluble nucleotides: they are removed from aqueous acid solutions with a water-insoluble amine dissolved in a water-immiscible solvent.  (+info)

Analysis of the physicochemical interactions between Clostridium difficile toxins and cholestyramine using liquid chromatography with post-column derivatization. (7/88)

A potential therapy for antibiotic-associated pseudomembranous colitis is to bind Clostridium difficile toxins A and B using cholestyramine, a hydrophobic anion exchange medium. Frontal analysis in isotonic phosphate buffer was studied using post-column derivatization with o-phthalaldehyde, which gave a highly sensitive (> or =30 ng) flow-through analysis. Following load (1.5-3.0 microg toxin/3.6 mg), toxin A was bound at a slightly higher capacity than B, due to slower kinetics. A salt gradient eluted roughly 20% of bound toxin A with 0.6 M NaCl and toxin B with 1.1 M NaCl, hence toxin A showed weaker electrostatic affinity. The remainder of toxin A (65%) and some of toxin B (10% out of 50%) were eluted using a subsequent gradient to 60% acetonitrile in normal saline, which measured predominantly hydrophobic binding. Low and high affinity populations of both toxins were observed. Glycocholic acid or amino acids were competitive binders, although these components had little effect on the toxin A population bound primarily through ionic interactions. Competitive protein constituents in hamster cecal contents were also profiled. These results help to explain the variable clinical response in using cholestyramine to treat colitis. Using quaternary amine-polyhydroxymethacrylate (PHM) ion exchange chromatography, a trend for increased binding at higher pH was observed, especially for toxin A. Binding to strong cation exchange resins (sulfonate-PHM) was not observed. A range of reversed phase media retained both toxins, although recovery was very poor relative to protein standards. Size exclusion chromatography with light scattering detection showed that toxin B exists in different aggregation states, while toxin A remains monomeric.  (+info)

Liquid-chromatographic analysis for neutral carbohydrates in serum glycoproteins. (8/88)

We describe a sensitive, reproducible procedure of analysis for the six neutral carbohydrates in glycoproteins, by high-resolution anion-exchange chromatography. As many as 16 neutral carbohydrates can be separated by elution with a concentration gradient of boric acid (pH 7, 67 to 672 mmol/liter). The carbohydrates are detected with a cerate oxidimetric detector system, which monitors the fluorescence of Ce3+ produced by the reaction of the eluted constituents with Ce4+. Sensitivity to 1 nmol of fucose is demonstrated. Analytical methods and results are presented for mannose, fucose, and galactose in serum glycoproteins for both normal women and those with metastatic breast cancer. We briefly discuss the possibility of separating and analyzing for the three neutral carbohydrates in serum glycoproteins in 4 h by isocratic (constant eluent concentration) elution from a chromatographic column.  (+info)

Radiotracer Technique in Study of Strongly Basic Anion Exchange Resins Dowex-SBR LC and Indion-454Radiotracer Technique in Study of Strongly Basic Anion Exchange Resins Dowex-SBR LC and Indion-454
The present paper demonstrates application of isotopic tracer technique in characterization of anion exchange resins Dowex-SBR LC and Indion-454 for which 131I and 82Br radio isotopes were used. The characterization was made based on iodide and bromide ion-isotopic exchange reaction kinetic data obtained for the two resins. It was observed that during iodide ion-isotopic exchange reaction performed at 35.0 °C, 1.000 g of ion exchange resins and 0.002 mol/L labeled iodide ion solution, the values of specific reaction rate (min-1), amount of ion exchanged (mmol), initial rate of ion exchange (mmol/min) and log Kd were 0.379, 0.426, 0.161 and 16.2 respectively for Dowex-SBR LC resin, which was higher than the respective values of 0.156, 0.243, 0.038 and 13.4 as that obtained by using Indion-454 resins. The identical trend was observed for the two resins during bromide ion-isotopic exchange reaction.

The counteranion exchange of quaternary 1,2,3-triazolium salts was examined using a simple method that permitted halide ions to be swap for a variety of anions using an anion exchange resin (A¯ form). The method was applied to 1,2,3-triazolium-based ionic liquids and the iodideto- anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Additionally, an anion exchange resin (N3¯ form) was used to obtain the benzyl azide from benzyl halide under mild reaction. Likewise, following a similar protocol, bis(azidomethyl)arenes were also synthesized in excellent yields.

Anion exchange resins (AERs) were compared with aluminum-based coagulants for reducing disinfection by-product (DBP) precursor concentrations from a source water collected in northeast Ohio, USA. Three AERs (IRA-910, IRA-958, and MIEX) were evaluated to determine which resin would remove the most natural organic matter (NOM) and moieties responsible for DBP formation. All the AERs were found to be highly proficient at NOM removal specifically the moieties that absorb UV254 (i.e., chromophores) over 75 min of contact time; however, MIEX removed NOM at a faster rate than IRA-910 and IRA-958 resins. Enhanced coagulation was effective at removing approximately 35% of the NOM and 40-60% of the chromophores and fluorophores (i.e., excitation-emission matrix pairs A and C). DBP formation was determined as a function of pH for the different NOM removal processes. MIEX treatment resulted in significant reduction in DBP concentrations when compared to chlorinating the raw source water. MIEX generally ...

Patent US6451123 - Process for the separation of sugars - Google PatentsPatent US6451123 - Process for the separation of sugars - Google Patents
Improved separations of xylose, mannose, galactose, arabinose, glucose, xylitol, arabitol; sorbitol, galactitol, or mannitol (and other monosaccharides and sugar alcohols) from other sugars and sugar alcohols may be achieved by chromatography over hydroxyl-form anion exchange surfaces prepared from anion exchange resins at relatively low hydroxyl concentrations. When a strong base anion exchange resin, such as a chloride-form strong base anion exchange resin, is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 mM, most preferably between 1 and 10 mM), the conditioned resin separates a number of sugars and sugar alcohols from one another, while still allowing ready desorption from the resin.

Indian Patents. 257678:AN IMPROVED PROCESS FOR THE RECOVERY OF EXTRACTION SOLVENT FORM BRINE SOLUTION
Prior art available in the literature is about the recovery of extraction solvent from degraded lean solvent stream. However, IIP has developed adsorption process for removal of salt from aqueous NMP. In this process aqueous NMP is first treated with a conditioned anion exchange resin to remove chlorides and any acidity. This is followed by treatment with cation exchange resin to remove added alkalinity. But this process does not work when salt content levels are higher than 5000 ppm. Moreover, additional infrastructure i.e. ion exchange columns are needed for this route. But present invention deals with altogether different problem i.e. recovery of extraction solvent from highly concentrated brine solution. To date no solution of such problem is discussed in the open literature. Also no patent is available. The present invention is a new idea generated in our laboratory ...

Hybrid anion exchange nanotechnology (HAIX-Nano) for concurrent trace by Michael Scott GermanHybrid anion exchange nanotechnology (HAIX-Nano) for concurrent trace by Michael Scott German
Millions of people across the Indian subcontinent are at risk of chronic exposure to arsenic and fluoride in aquifers with excess TDS (|500 mg/L). Hybrid anion exchange resins with nanoparticles of zirconium oxide (HAIX-NanoZr) were created for effective fluoride removal; zirconium oxide selectively bound fluoride, silica, and phosphate. The zeta potential of HAIX-NanoZr was directly correlated to the fluoride removal capacity. Thus, to increase fluoride capacity and achieve partial desalination concurrently, a weak acid cation (WAC) exchange pretreatment was used to lower alkalinity, hardness, pH, and TDS. Consistent partial desalination (~50%) occurred in proportion to influent alkalinity and hardness. With regular acid conditioning of WAC, the fluoride capacity of HAIX-NanoZr increased 10x, 300 bed volumes (BVs) to 3500 BVs. Upon regeneration with 2% NaOH, |95% of capacity was restored; fluoride treatment was identical over three consecutive cycles with water from a fluoride-contaminated well (Nakuru

A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A− form) in non-aqueous media. The anion loading of the AER (OH− form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A− form) method in organic solvents was then applied to several quaternary heteroaromatic salts and ILs, and the anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Relying on the hydrophobicity of the targeted ion pair for the counteranion swap, organic solvents with variable polarity were used, such as CH3OH, CH3CN and the dipolar nonhydroxylic solvent mixture CH3CN:CH2Cl2 (3:7) and the anion exchange was equally successful with both lipophilic cations and anions.

Peptide-oligonucleotide conjugates were synthesized using two strategies: a mimetic signal peptide-conjugated oligonucleotide was assembled stepwise on CPG by using 2,2-dimethyl-3-hydroxypropionic acid as a linker. To solve the precipitation problem in the coupling reaction caused by the electrostatic interaction of arginine-rich peptides and oligonucleotide, oligonucleotides were absorbed on an anion-exchange resin, and then the on-resin fragment was applied for the conjugation with arginine-rich peptide. The peptide-antisense oligonucleotides showed permeability to the cell membrane of HepG-2 cells. ...

Laboratoire de Phytopathologie Moleculaire, URA CNRS 1128, Universite Paris-sud, Orsay, France.. A new Arabidopsis thaliana (ecotype Columbia) genomic library has been constructed in Yeast Artificial Chromosomes: the CIC library (for CEPH, INRA and CNRS). Optimization of plant culture conditions and protoplast preparation allowed the recovery of large amounts of viable protoplasts. Mechanical shearing of DNA was minimized by isolation of DNA from protoplasts embedded in agarose. Cloning of large inserts was favored by including two successive size fractionation steps (after partial EcoRI digestion and after ligation with the vector arms), which selected DNA fragments larger than 350 kb. The library consists of 1152 clones with an average insert size of 420 kb. Clones carrying chloroplast DNA and various nuclear repeated sequences have been identified. Twenty-one per cent of the clones are found to contain chloroplast DNA. Therefore, the library represents around four nuclear genome equivalents. ...

De Mineralization (DM) Plant
Deionization also called as Demineralization, is an ion exchange resin based process which can generate water, free of dissolved salt. DM process configuration includes basic cationic and anionic beds. Typically, the cation resin operates in the hydrogen cycle. The cations in the water (i.e. calcium, magnesium and sodium) pass through the canion exchange resin where they are chemically exchanged for hydrogen ions. The Water then passes through the anion exchange resin where the anions (i.e. chloride, sulphate, nitrate and bicarbonate) are chemically exchange for hydroxide ions. The final water from this process consists essentially of hydrogen ions and hydroxide ions, which is the chemical composition of pure water.. ...

Colestyramine - WikipediaColestyramine - Wikipedia
Colestyramine (INN) or cholestyramine (USAN) (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin, which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them strongly in the resin matrix. The functional group of the anion exchange resin is a quaternary ammonium group attached to an inert styrene-divinylbenzene copolymer. Colestyramine removes bile acids from the body by forming insoluble complexes with bile acids in the intestine, which are then excreted in the feces. As a result of this loss of bile acids, more plasma cholesterol is converted to bile acids in the liver to normalise levels. This conversion of cholesterol into bile acids lowers plasma cholesterol levels. Bile acid sequestrants such as colestyramine were first used to treat hypercholesterolemia, but since the introduction of statins, ...

COLESTID® TABLETS (micronized colestipol HCl tablets) Warnings and Precautions | Pfizer Medical Information - NigeriaCOLESTID® TABLETS (micronized colestipol HCl tablets) Warnings and Precautions | Pfizer Medical Information - Nigeria
Since colestipol hydrochloride is an anion exchange resin, it may have a strong affinity for anions other than the bile acids. In vitro studies have indicated that colestipol hydrochloride binds a number of drugs. Therefore, COLESTID Tablets may delay or reduce the absorption of concomitant oral medication. The interval between the administration of COLESTID Tablets and any other medication should be as long as possible. Patients should take other drugs at least one hour before or four hours after COLESTID Tablets to avoid impeding their absorption.. Repeated doses of colestipol hydrochloride given prior to a single dose of propranolol in human trials have been reported to decrease propranolol absorption. However, in a follow-up study in normal subjects, single-dose administration of colestipol hydrochloride and propranolol and twice-a-day administration for 5 days of both agents did not affect the extent of propranolol absorption, but had a small yet statistically significant effect on its rate ...

Frontiers | The Effect of Antioxidants on the Properties of Red Blood Cells From Patients With Sickle Cell Anemia | PhysiologyFrontiers | The Effect of Antioxidants on the Properties of Red Blood Cells From Patients With Sickle Cell Anemia | Physiology
Oxidative damage to red blood cells (RBCs) may contribute to pathogenesis of sickle cell anemia. Reducing the deleterious effects of oxidants by exposing RBCs to a number of antioxidants has been shown to have protective effects against lipid and protein peroxidation. We hypothesize that antioxidants may also have beneficial effects on the abnormal membrane permeability of sickle cells. Increased cation permeability of these cells encourages HbS polymerization by causing RBC dehydration and also leads to externalization of the prothrombotic aminophospholipid phosphatidylserine (PS). Three antioxidants with different mechanisms of action were investigated - dithiothreitol, N-acetylcysteine, and quercetin. All three were found to inhibit the main cation pathways responsible for dehydration - the deoxygenation-induced cation conductance (or Psickle), the Ca2+-activated K+ channel (or Gardos channel), and the K+-Cl− cotransporter. They also reduced Ca2+-induced PS exposure and hemolysis. Findings provide

Hybrid ion exchangers containing Fe(III)-Cu(II) binary oxides obtained using macroreticular anion exchanger
Considering the performance of parent Fe(III)-Cu(II) binary oxide nanoparticles in removing numerous contaminants from water, in order to prevent the release of the nanostructures into the cleaned water a deposit with the same composition was introduced into the matrix of a synthetic porous material (ion exchange resin), whereby a hybrid ion exchanger (HIX) was obtained. Amberlite 900 Cl, a commercially available strongly basic macroreticular anion exchanger, was used as the supporting material. The inorganic deposit was introduced into its structure in two steps performed batchwise at ambient temperature. Fe(III)-Cu(II) binary oxide could be deposited into the matrix of the strongly basic anion exchanger owing to the affinity of its functional groups for FeCl4− and CuCl42− ions. When in the ion exchange reaction the anion exchanger bound both the ions and the reaction medium alkalized, the respective oxides FeOOH and CuO precipitated in its structure. The oxide deposit was introduced into ...

Rapid Separation of a Tuberculosis Medication using UHPLC | JASCORapid Separation of a Tuberculosis Medication using UHPLC | JASCO
Figure 2 Separation of a 1 µL sample injection using UHPLC. A flow rate of 0.8 mL/min, nearly half that of the HPLC separation, was used for elution of the sample using an X-PressPak C18S column with 2 µm particles (2.1 mm i.d. X 50 mm L). This resulted in an analysis time of 1.3 min, approximately 7 times faster than the HPLC separation. The gradient elution program of 1.5 min is 10 times shorter than that for HPLC..

Saturday 20 September 1662 (The Diary of Samuel Pepys)Saturday 20 September 1662 (The Diary of Samuel Pepys)
Lead was also used, in later times, to seal tin cans when canning of meat was first introduced: they didnt understand the connection even in the 19th century. Sams long time successor in the Navy Victualling office in the 19th century decided that HM Navy should have the new tinned meat - the ratings were suspicious of the new food preferring the old salt pork (which Sams ratings would have had). They called the new canned meat sweet FA - commenting on the unknown origins of the meat. Sweet FA was Sweet Fanny Adams a London girl who was abducted, abused, murdered and dumped. The case was a newspaper sensation - she was always called Sweet Fanny Adams. The ratings were right to be suspicious: lead poisoning is thought to have been a main cause for the disaster of the vanished Franklin expedition to discover the NW passage. Probably language hat is now going to tell us all that this is *not* the derivation of sweet FA, but it is what I read somewhere (probably to do with the Franklin ...

Here, we developed a straightforward methodology to generate TCRαβ negative (allogeneic) cells for CAR-T cell therapies. With an early and transient expression of an anti-CD3 CAR in the engineered donor T cells, we programmed these cells to self-eliminate the TCR+ cell population and obtained an ultrapure TCRαβ- population (99-99.9%) at the end of the CAR-T production.

Vadim- I have re-nickelated Ni-NTA-agarose resins with varying success. I believe Qiagen provides a protocol for doing this.

Alternatively, I have also used Ni-NTA columns many more than 5 times and have had pretty good resolution. Since these resins are available for about $5/ml, I would suggest using the resin as long as you still get good resolution and then either replace it (if it is a relatively small volume), or attempting to regenerate it if it is a large volume ...

Dental BondingDental Bonding
What does dental bonding involve?. To begin, the dentist will isolate the teeth included in the procedure, etching them in preparation for bonding. After applying the etching conditioning liquid, the surface of the teeth will have small crevices that allow the tooth stronger adhesion with the bonding agent. The dentist will then apply a bonding resin which cements the composite in place. After several layers of tooth-colored composite are applied, the composite and bonding resin are shaped and hardened with a specially calibrated light. Once the composite is fully set, the bonded areas are smoothed, buffed, and polished to blend in naturally with the surrounding teeth. If you want to regain confidence in your smile, contact our practice to learn more about bonding.. ...
