The use of histological techniques for the demonstration of ion exchange resins. (1/144)
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)Nonbiological fractionation of iron isotopes. (2/144)
Laboratory experiments demonstrate that iron isotopes can be chemically fractionated in the absence of biology. Isotopic variations comparable to those seen during microbially mediated reduction of ferrihydrite are observed. Fractionation may occur in aqueous solution during equilibration between inorganic iron complexes. These findings provide insight into the mechanisms of iron isotope fractionation and suggest that nonbiological processes may contribute to iron isotope variations observed in sediments. (+info)Reconcentration of poliovirus from sewage. (3/144)
Virus can be adsorbed from effluents of sewage treatment plants on large-surface membranes. Subsequent elution of virus requires large volumes, which in turn requires reconcentration of virus for assay. However, reconcentration of such viral eluates on small adsorbent surfaces is difficult because certain soluble sewage components are adsorbed along with the virus on the initial virus adsorbent and are removed along with the virus by the eluent. Upon acidification of the initial eluate to reconcentrate the virus on smaller membrane surfaces, flocs are formed that interfere with the reconcentration process. To circumvent this problem, the interfering sewage components can be removed by activated carbon and ion-exchange resins. The virus is then readily reconcentrated on small membranes. (+info)Concentration and purification of enteroviruses by membrane chromatography. (4/144)
A simple procedure for the concentration and partial purification of enteroviruses from tissue culture harvests is described. After removal of acid-precipitating components with a cationic detergent, the detergent and most membrane-coating components were removed by treatment with a cationic-exchange resin. The resin effluent was then acidified, and the virus was adsorbed to epoxy-fiberglass membranes. Virus was then eluted with pH 11.5 glycine-NaOH buffer. Since this eluate contains no orgcentrated simply by acidifying the eluate and passing it through a smaller membrane than that used for the first concentration. As high as 500-fold concentrations can be achieved, with a high efficiency of recovery. (+info)Actin-like properties from Escherichia coli: concept of cytotonus as the missing link between cell metabolism and the biological ion-exchange resin. (5/144)
A protein fraction (A-L fraction) with characteristics reminiscent of muscle actin has been isolated from Escherichia coli. The A-L fraction undergoes reversible aggregation under the same conditions in which actin is polymerized and depends primarily on potassium for its polymerization. This fraction, upon electrophoresis on acrylamide gels in the presence of sodium dodecyl sulfate, exhibits a distinct peak at the characteristic molecular weight of 45,000. Passage of skeletal muscle myosin through the A-L fraction specifically removes this 45,000-molecular weight peak. Examination of the myosin by sodium dodecyl sulfate electrophoresis after the passage reveals a new band at the proper molecular weight. The A-L fraction from wild-type E. coli is compared with the protein from a potassium transport mutant. Important catalytic differences exist between the A-L fractions of the two strains. The A-L fraction from the mutant fails to polymerize in low-K media in the K+ concentration range in which the mutant fails to take up to K+. In low-K+ media, the parent strain accumulates potassium and the A-L fraction from this organism polymerizes. The cell swelling reaction of both strains has been studied. Parent cells swell during low-K+ uptake, whereas the mutant does not. It is construed from this that the differences in the characterization of the A-L fraction relative to that of the wild type are related to the loss of cell swelling in the mutant and hence to the loss in alkali cation selectivity. The possible role of contractile proteins in biological ion exchange is discussed. (+info)Acute colitis in the renal allograft recipient. (6/144)
Four renal allograft recipients with evidence of ischemic damage to the colon are presented and compared with 11 cases from 5 major series. Similarities in the patients included: deterioration of renal function, multiple immunosuppressive and antibiotic regimens, the use of cadaver renal allografts, and diagnostic and therapeutic measures requiring frequent enemas with barium and ion-exchange resins. Two of our patients underwent surgery for the removal of segments of necrotic colon after several weeks of fever and abdominal pain initially attributed to either acute rejection, viral infection, or pancreatitis. One patient had three days of melena and responded to non-operative therapy. The fourth patient developed ischemic colonic changes 10 weeks after allograft nephrectomy and was receiving no immunosuppression at the time. Broad spectrum antibiotics were used at various times in all patients. Early aggressive evaluation of gastrointestinal complaints--including barium enema, upper gastrointestinal series with small bowel follow-through, proctosigmoidoscopy or colonoscopy, and arteriography--is indicated, in view of the lethality of the complication of colonic ulceration. The clinical pictures presented emphasize the fact that recipients of renal allografts are commonly heir to many complications which may be considered rare in the normal population. (+info)The measurement of iron-binding capacity in serum and purified transferrin with the aid of chemical affinity chromatography. (7/144)
In a mew method for the estimation of transferrin by iron-binding capacity iron is added as the tartrate in NaCl with about 10 mM bicarbonate. The excess iron is removed by passage through DEAE-Sephadex A-50 previously treated with the iron chelator disodium catechol-3,5-disulphonate. The iron remaining bound to transferrin is measured without protein precipitation by the use of ferrozine. The method is applicable to fresh, frozen, or lyophilized serum, purified transferrin, and some quality control preparations. Validation experiments confirm that transferrin in serum and in pure solution is saturated with iron and give some evidence of specificity. The possible use of commercially available transferrin preparations as analytical reference standards is discussed. (+info)The losozyme from Asterias rubens. (8/144)

The quantitative amino acid composition, the molecular weight and the N-terminal sequence determined by a sequencer are reported. This new invertebrate enzyme presents important differences when compared to previously studied lysozymes. (+info)Ion exchange resins are insoluble, cross-linked polymeric materials that contain functional groups which can exchange ions with surrounding solutions. These resins are typically used in water treatment and purification processes to remove unwanted dissolved ions, molecules, or gases. They operate through the principle of ion exchange, where ions held on the resin are exchanged for ions in the solution. The process can be used to soften water, remove heavy metals, treat wastewater, and deionize water, among other applications.
The resins consist of a three-dimensional network of cross-linked polymer chains, providing a large surface area for ion exchange. They are often made from styrene and divinylbenzene monomers, which form a rigid structure that can withstand repeated ion exchange cycles without losing its shape or functionality. The functional groups on the resins can be cationic (positively charged) or anionic (negatively charged), allowing them to attract and retain ions of opposite charge from the surrounding solution.
Cation exchange resins are used to remove positively charged ions, such as calcium, magnesium, sodium, and potassium, while anion exchange resins are used to remove negatively charged ions, such as chloride, sulfate, nitrate, and bicarbonate. The resins can be regenerated by washing them with a strong solution of the ion to be recovered, allowing them to be reused multiple times before they need to be replaced.
Cation exchange resins are a type of ion exchange resin that are positively charged and used to remove cations (positively charged ions) from aqueous solutions. They are often used in water treatment to soften water by removing calcium and magnesium ions, which can cause scale buildup in pipes and appliances. Cation exchange resins can also be used to remove heavy metals and other contaminants from water.
The resin itself is typically made of a cross-linked polymer matrix, such as polystyrene or polyacrylate, which contains functional groups that give the resin its ion exchange properties. The most common type of cation exchange resin is the sulfonated styrene divinylbenzene copolymer (SSDVB), in which the functional group is a sulfonic acid (-SO3H) group. When this resin comes into contact with a solution containing cations, such as a water supply, the cations in the solution will replace the hydrogen ions on the resin, causing the resin to become positively charged and the solution to become deionized.
Cation exchange resins can be regenerated by washing them with a strong acid, which replaces the captured cations with hydrogen ions, allowing the resin to be reused. The regeneration process must be done carefully to avoid damaging the resin and to ensure that it is properly rinsed of any residual acid before being put back into service.
Cation exchange resins are widely used in various industries such as pharmaceuticals, food and beverage, power generation, chemical processing and metal finishing for purification of water and wastewater treatment.
Anion exchange resins are a type of ion exchange resin that are positively charged and used to remove anions (negatively charged ions) from aqueous solutions. These resins contain functional groups such as quaternary ammonium or tertiary amine groups, which can attract and retain anions like chloride, sulfate, or nitrate ions.
Anion exchange resins are commonly used in water treatment to remove excess dissolved salts, heavy metals, and other impurities from drinking water, industrial wastewater, and process water. They can also be used in the pharmaceutical industry for the purification of drugs and biomolecules, as well as in research and analytical applications.
When anions come into contact with the resin, they are attracted to the positively charged functional groups and exchanged for hydroxide ions (OH-) present on the resin surface. This exchange results in the formation of water and the release of the anion from the resin. The resin can then be regenerated by washing it with a strong base, which replaces the hydroxide ions and restores its ability to exchange anions.
Overall, anion exchange resins are important tools for removing unwanted anions from various types of solutions, including water, biological samples, and industrial process streams.
I apologize for any confusion, but "Pinus ponderosa" is not a medical term. It is the scientific name for a species of pine tree commonly known as the western yellow pine or ponderosa pine. This tree is native to North America and is one of the most widely distributed pine species in the continent.
Here's a brief overview of its botanical characteristics:
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales
Family: Pinaceae
Genus: Pinus
Species: P. ponderosa
The ponderosa pine is a large evergreen tree, reaching heights of 150-250 feet (46-76 meters) tall and trunk diameters up to 8 feet (2.4 meters). Its needle-like leaves are grouped in bundles of three, and its cones are long and slender, typically 3-6 inches (7.6-15.2 cm) in length.
If you have any questions related to medical terminology or healthcare topics, please feel free to provide them, and I'd be happy to help.
Synthetic resins are artificially produced substances that have properties similar to natural resins. They are typically created through polymerization, a process in which small molecules called monomers chemically bind together to form larger, more complex structures known as polymers.
Synthetic resins can be classified into several categories based on their chemical composition and properties, including:
1. Thermosetting resins: These resins undergo a chemical reaction when heated, resulting in a rigid and infusible material that cannot be melted or reformed once it has cured. Examples include epoxy, phenolic, and unsaturated polyester resins.
2. Thermoplastic resins: These resins can be repeatedly softened and hardened by heating and cooling without undergoing any significant chemical changes. Examples include polyethylene, polypropylene, and polystyrene.
3. Elastomeric resins: These resins have the ability to stretch and return to their original shape when released, making them ideal for use in applications that require flexibility and durability. Examples include natural rubber, silicone rubber, and polyurethane.
Synthetic resins are widely used in various industries, including construction, automotive, electronics, and healthcare. In the medical field, they may be used to create dental restorations, medical devices, and drug delivery systems, among other applications.
Epichlorohydrin is an industrial chemical with the formula C3H5ClO. It is a colorless liquid with an irritating odor, and it is used primarily as a building block in the production of other chemicals, including epoxy resins, synthetic gums, and plastics. Epichlorohydrin is produced by reacting chlorine with propylene in the presence of a catalyst. It is classified as a probable human carcinogen based on evidence from animal studies, and exposure to this chemical can cause irritation of the eyes, skin, and respiratory tract. Therefore, it is important to handle epichlorohydrin with care and to use appropriate safety measures when working with this chemical.
Ion exchange chromatography is a type of chromatography technique used to separate and analyze charged molecules (ions) based on their ability to exchange bound ions in a solid resin or gel with ions of similar charge in the mobile phase. The stationary phase, often called an ion exchanger, contains fixed ated functional groups that can attract counter-ions of opposite charge from the sample mixture.
In this technique, the sample is loaded onto an ion exchange column containing the charged resin or gel. As the sample moves through the column, ions in the sample compete for binding sites on the stationary phase with ions already present in the column. The ions that bind most strongly to the stationary phase will elute (come off) slower than those that bind more weakly.
Ion exchange chromatography can be performed using either cation exchangers, which exchange positive ions (cations), or anion exchangers, which exchange negative ions (anions). The pH and ionic strength of the mobile phase can be adjusted to control the binding and elution of specific ions.
Ion exchange chromatography is widely used in various applications such as water treatment, protein purification, and chemical analysis.
Diphenhydramine is an antihistamine medication used to relieve symptoms of allergies, such as sneezing, runny nose, and itchy or watery eyes. It works by blocking the action of histamine, a substance in the body that causes allergic reactions. Diphenhydramine can also be used to treat motion sickness, insomnia, and symptoms of the common cold.
In addition to its antihistamine effects, diphenhydramine also has anticholinergic properties, which means it can help to reduce secretions in the nose and throat, and may have a drying effect on the mouth and eyes. It is available over-the-counter in various forms, including tablets, capsules, liquid, and topical creams or ointments.
It's important to note that diphenhydramine can cause drowsiness, so it should be used with caution when operating heavy machinery or driving a vehicle. It may also interact with other medications, so it's important to speak with a healthcare provider before taking this medication.
I'm sorry for any confusion, but "Polystyrenes" is not a medical term. Polystyrene is a type of synthetic aromatic hydrocarbon polymer that is used in a variety of commercial and industrial products, such as packaging materials, insulation, and disposable cutlery. It's important to note that some polystyrene products may contain potentially harmful chemicals, such as styrene, which can leach out into food or drink, posing potential health risks. However, the medical community primarily deals with the health effects of exposure to these chemicals rather than defining the material itself.
Ion exchange is not a medical term per se, but it is a process that is used in various medical and healthcare applications. Here's a general definition:
Ion exchange is a reversible chemical reaction where ions are exchanged between two electrolytes or between an electrolyte and a solid phase. In the context of medical and healthcare applications, ion exchange resins are often used to remove unwanted ions or to add beneficial ones in various settings such as water treatment, dialysis, and drug delivery systems.
In water treatment, for example, ion exchange resins can be used to soften hard water by exchanging calcium and magnesium ions with sodium ions. In hemodialysis, ion exchange membranes are used to selectively remove waste products and excess fluids from the blood of patients with kidney failure. Ion exchange resins are also used in some drug delivery systems to control the release of drugs in a targeted and sustained manner.
In a medical context, "resins, plant" refer to the sticky, often aromatic substances produced by certain plants. These resins are typically composed of a mixture of volatile oils, terpenes, and rosin acids. They may be present in various parts of the plant, including leaves, stems, and roots, and are often found in specialized structures such as glands or ducts.
Plant resins have been used for centuries in traditional medicine and other applications. Some resins have antimicrobial, anti-inflammatory, or analgesic properties and have been used to treat a variety of ailments, including skin conditions, respiratory infections, and pain.
Examples of plant resins with medicinal uses include:
* Frankincense (Boswellia spp.) resin has been used in traditional medicine to treat inflammation, arthritis, and asthma.
* Myrrh (Commiphora spp.) resin has been used as an antiseptic, astringent, and anti-inflammatory agent.
* Pine resin has been used topically for its antimicrobial and anti-inflammatory properties.
It's important to note that while some plant resins have demonstrated medicinal benefits, they should be used with caution and under the guidance of a healthcare professional. Some resins can have adverse effects or interact with medications, and it's essential to ensure their safe and effective use.
Composite resins, also known as dental composites or filling materials, are a type of restorative material used in dentistry to restore the function, integrity, and morphology of missing tooth structure. They are called composite resins because they are composed of a combination of materials, including a resin matrix (usually made of bisphenol A-glycidyl methacrylate or urethane dimethacrylate) and filler particles (commonly made of silica, quartz, or glass).
The composite resins are widely used in modern dentistry due to their excellent esthetic properties, ease of handling, and ability to bond directly to tooth structure. They can be used for a variety of restorative procedures, including direct and indirect fillings, veneers, inlays, onlays, and crowns.
Composite resins are available in various shades and opacities, allowing dentists to match the color and translucency of natural teeth closely. They also have good wear resistance, strength, and durability, making them a popular choice for both anterior and posterior restorations. However, composite resins may be prone to staining over time and may require more frequent replacement compared to other types of restorative materials.
