Chelation is the process whereby an organic moiety acts as a ligand to bind a metal ion through two or more coordination bonds. Some low-molecular-weight compounds that may be released during the digestion of food can act as metal chelators and increase metal solubility in the intestinal lumen. In some circumstances, chelated forms of metals are naturally present in food, such as heme iron (part of hemoglobin or myoglobin protein) found in meat. Heme is a stable protoporphyrin ring-containing compound that protects a central iron atom from interacting with other potentially deleterious compounds, such as phytic acid, that would reduce its availability and inhibit iron absorption. Nonheme iron bioavail-ability is affected by various enhancing and inhibitory substances found in food. In contrast, heme iron bio-availability is not. The heme moiety is absorbed intact by the enterocyte. Inside the enterocyte a cytosolic enzyme heme oxygenase breaks apart the protopor-phyrin ring and...

Discussion And Summary

The negative effects of phytate in food on human health are likely to be most pronounced in people on marginal subsistence diets that consist mainly of seeds grains fruits. Over two billion humans, largely located in developing countries, have micronutrient deficiencies 42-44 . Considerable scientific literature indicates that the strong chelation capacity of PA can decrease the uptake of elements such as Ca, Fe, and Zn in monogastric digestive tracts 20,45-47 .

Isolation and Purification of DNA Fragments for Microinjection

Tris-Borate EDTA buffer (TBE) 89 mM Tris-HCl (pH 8.3), 89 mM boric acid, 2 mM EDTA. Made as a 5X stock solution and diluted to 1X as required with the addition of deionized water (Elga, High Wycombe, Bucks, UK) containing 0.5 g mL ethidium bromide (from a 10 mg mL stock). 11. Microinjection buffer 10 mM Tris-HCl, pH 7.4, 0.1 mM EDTA. Make up using high-quality, endotoxin-free water that has preferably been embryo-tested (e.g.,W1053, Sigma). Sterilize by passage through a 0.22- im filter. Store in 10-mL aliquots at -20 C.

Measurement of Blood Levels

Blood sample collection and processing are critical factors in the determination of homocysteine concentrations. Typically, blood samples for homocys-teine analysis are collected in tubes containing an anticoagulant (e.g., EDTA, heparin). Prompt separation of plasma from the blood cells after centrifuga-tion is required to avoid excess release of intracellular homocysteine into the plasma or removal of homocysteine from the plasma by meta-bolically active leucocytes after blood draw. Keeping the blood sample cold until centrifugation and separation (ideally within 4 h of blood draw) minimizes this problem. Serum homocysteine concentrations typically exceed plasma concentrations by 20 . This is likely due to the fact that blood collected to isolate serum (i.e., without an anticoagulant) must clot at room temperature for 30-60 min before centrifugation and separation. Therefore, plasma is preferred for measurement of homocys-teine. Once separated from the blood cells, the concentration...

Chemical Components

Ferrous sulfate Is the most widely studied form. Other ferrous forms Include ascorbate, carbonate, citrate, fumarate, gluconate, lactate, succinate and tartarate (non-haem Iron). Iron from ferrous sulfate has a significantly greater bioavailability than ferrous glycine chelate or ferric EDTA (Ferreira da Silva et al 2004). Other ferric forms include ammonium citrate, chloride, citrate, pyrophosphate and sulfate. Amino acid chelates, such as iron glycine, are also available. Dietary ferritin is equally well absorbed as ferrous sulfate and therefore food sources are likely to be effective (Davila-Hicks et al 2004). Cooking in iron pots may also improve iron status (Geerligs et al 2003).

Ivpotential Adverse Effects

Very few studies have addressed the question of adverse effects of consuming high quantities of spice extracts or polyphenolic antioxidants. Since one of the postulated mechanisms of antioxidant action is chelation of pro-oxidant metals such as iron, a recent human study examined the effect of polypheno-lic-rich green tea and rosemary extracts on the absorption of nonheme iron (71). It was found that green tea and rosemary extracts added to foods decreased absorption of nonheme iron by around 20 , indicating that indeed

Ivflavonoids And Cardiovascular Disease

Flavonoids are powerful antioxidants, and their activity is related to their chemical structures (76-78). Plant flavonoids can act as potent inhibitors of LDL oxidation, via several mechanisms, including scavenging of free radicals, chelation of transition metal ions, and preservation of serum para-oxonase (PON1) activity (and as a result hydrolysis of LDL-associated lipid peroxides).

Applications To Health Promotion And Disease Prevention

Moringa oleifera seed extracts are rich sources of a number of vitamins and minerals (Table 92.1), which may contribute significantly to its antioxidant, therapeutic, and nutritional values. Extending its utility as a water purifier, we reported therapeutic potential of MOS in arsenic poisoning in vivo (Mishra et al., 2009). MOS contain natural coagulants useful for chelation and for their antioxidant property. These beneficial effects are both direct and indirect, and may be attributed to high concentrations of methionine, cysteine, and anti-oxidants such as vitamins C, E, b-carotene, etc. Methionine and cysteine are rich in the SH group, which provides a binding site for arsenic. In the oxidative methylation reaction, where trivalent forms of arsenic are sequentially methylated to form mono- and di-methy-lated products, S-adenosyl methionine (SAM) functions as a methyl donor and glutathione (GSH) as an essential co-factor. SAM is synthesized from condensation of ATP with L- Major...

Potential Importance of Flavonoids to Human Health Molecular Mechanisms of Action

Membrane function is understood to be of vital importance to many cellular processes, including the role of membrane enzymes and receptors in cell growth and signalling. Membrane function may be influenced by dietary components directly by altering membrane fluidity or indirectly by protection against the free radical-mediated process of membrane lipid peroxidation. This can arise from oxida-tive stress and result in oxidative membrane damage. Flavonoids such as quercetin and myrecetin have been widely found to inhibit membrane lipid peroxidation. Flavonoids inhibit lipid peroxidation in vitro by acting as chain-breaking antioxidants They donate a hydrogen atom to lipid radicals, thus terminating the chain reaction of lipid peroxidation. Additionally, flavonoids can act as metal chelating agents. Furthermore, kaempferol-3-O-galactoside protected mice against bromobenzene-induced hepatic lipid peroxidation. The relative potencies of flavonoids as antioxidants is governed by a set of...

Salmonella Pathogenicity Island

Genes encoded by Salmonella pathogenicity island 2 (SPI2) have been shown to be iron-responsive with transcription upregulated during iron chelation (Zaharik et al. 2002). The S. Typhimurium SPI2-associated genes are required for intramacrophage survival and systemic infection, which are iron-deplete environments. Microarray analysis indicates that the transcription of 13 SPI2-associated genes (Fig. 13.2,

Phytate As An Antioxidant In Chicken And Beef

Graf and coworkers 2,12 were the first to evaluate phytate as an antioxidant in a meat system. In cooked, minced chicken breast muscle +10 added water, phytic acid (1.5 mM, pH 6.0) was highly effective in reducing thiobarbituric acid (TBA) values (Figure 12.1) and warmed-over flavor (WOF) intensity (Figure 12.2), compared to controls 12 . Phytic acid (2 mM) was more effective than other antioxidants (2 mM ascorbic acid, BHT, or EDTA) for lowering TBA values in fresh beef homogenates incubated for 60 min at 37 C 13 .

Defining Alternative Therapies

Identify a specific condition and attempting to treat the condition with specific medications, rehabilitative therapies, and sometimes surgery. The terms conventional and allopathic are often used when referring to Western-based therapies. A larger variety of terms are used when referring to alternative therapies. These include alternative, Eastern medicine, complementary medicine, CAM, integrative, functional, natural, and holistic medicine. In essence, what all of these terms imply is a form of therapy not considered to be a standard Western medical approach. Hence, the list of alternative therapies is infinite and might include a variety of treatments such as aroma therapy, magnet therapy, chelation, acupuncture, and meditation. Because there is such a vast array of different alternative approaches, it is important to define the specific therapy such as a particular herbal remedy or exercise when discussing and assessing the response to a therapy rather than using the term...

Possible Mechanisms Of Anticancer Effects

Also due to its structure, PA can chelate polyvalent cations, such as iron, calcium and zinc 83 Figure 14.3(C) . These minerals are required for vital cellular functions, and their chelation may affect cellular growth kinetics. The chelation of minerals vital to DNA synthesis and cell growth may be a factor in studies that have shown a decrease in cell proliferation with PA supplementation 13,17 . This may also be a mechanism in the protective effects of PA on human rhabdomyosarcoma 59 and HepG2 liver cancer cells in athymic mice, where PA was injected directly into the tumor. In fact, studies have shown that PA can reduce increased colonic cell proliferation 15 and inhibit colon tumorigenesis 33 induced by the addition of minerals such as iron to the diet. Because the iron necessary to catalyze hydroxyl radical production may be diet derived 88 , its chelation by PA may inhibit hydroxyl radical production and subsequent oxidative damage Figure 14.3(C) . In fact, individuals consuming...

How I Was Cured of Chronic Fatigue

There are no longer any silver mercury amalgam dental fillings in my mouth. I have been through 6 chelation treatments. Chelation is a method of extracting mercury from human chemistry. By directing my efforts at removing the silver mercury amalgam fillings in my teeth, and by going through chelation to remove the accumulation of mercury in

Antibacterial activity

Ellison et al. (1988) hypothesized that the iron-binding proteins could affect the Gram-negative outer membrane in a manner similar to that of the chelator EDTA. Further, both the whole protein and a cationic N-terminus peptide fragment directly damage the outer membrane of Gram-negative bacteria suggesting a mechanism for the supplemental effects. Several groups have also shown that LF could synergistically interact with immunoglobins, complement, and neutrophil cationic proteins against Gram-negative bacteria.

Muscle Strength Stamina Collagen Metabolism

The molecular mechanism of this antimutagenic activity may be related to its reported antioxidant properties. Leaf extract of Du-Zhong had an inhibitory effect on oxidative damage in biomolecules such as deoxyribose, DNA, and 2'-deoxyguanosine (2'-dG) as induced by the Fenton reaction (22). All of the Du-Zhong extract inhibited the oxidation of deoxyribose induced by Fe(3+)-EDTA H2O2 ascorbic acid in a concentration-dependent manner. At a concentration of 1.14 mg mL, the inhibitory effect of the extracts of leaves, roasted cortex, and raw cortex was 85.2 , 68.0 , and 49.3 , respectively. The extract of leaves inhibited the strand breaking of DNA induced by the Fenton reaction at concentrations of 5 and 10 Ag iL. The leaf extract had a marked inhibitory effect on Fenton-reaction-induced oxidative damage in biomolecules. The extract of roasted cortex exhibited modest inhibition while the extract of raw cortex had the least inhibitory effect on oxidative damage in biomolecules. This is...

Gynemed Gm501 Composition

Embryo Culture Media culture media consists of inorganic ions from salts. All commercial human embryo culture media share the same six inorganic ions Na+, K+, Cl-, Ca2+, Mg2+, and SO42-, which are the same ones that were included in the first defined mouse embryo culture media formulated in the 1950s (1, 2). Most media also contain PO42-, although several that were created specifically for eggs and cleavage stage embryos are phosphate-free. Of these six or seven inorganic ion species, Na+ and Cl- are present at by far the largest concentrations in every medium. In addition, much lower concentrations of other inorganic ions are likely present during embryo culture, mainly introduced when the media are supplemented with protein sources such as serum or serum albumin, since serum albumin has a high binding capacity for ions such as Cu2+ and Zn2+ (3). Serum albumin and similar medium constituents, and EDTA, also exert a beneficial effect by chelating these and other ions that can be toxic...

Stressor Induced Bacterial Translocation

Several studies have demonstrated that immobilizing rats in a cold environment significantly increased jejunal permeability to 51Cr-EDTA and mannitol (Saunders et al. 1994) via a cholinergic dependent mechanism (Saunders et al. 1997 Soderholm and Perdue 2001). In the colon, permeability was also increased by immobilization in a cold environment, an effect that could be mimicked by peripheral injection of CRH (Saunders et al. 2002 Soderholm and Perdue 2001).

Phytatemineral Interactions

The relative binding strengths of different minerals to phytic acid vary greatly. Chelation strength increases with increasing atomic number of the mineral moving from the alkaline earth metals through transition metals in the periodic table. Vohra et al. 13 , using titration curves of phytate as free acid in the presence of single cations, reported that phytate forms complexes with cations in the following descending order of strength

Dietary Management of Secondary Overnutrition

Chelating agents in Wilson's disease and recurrent phlebotomy in hemochromatosis. In a related variant condition, African hemosiderosis, common among Bantu in southern Africa, removing concentrated iron sources from the diet, specifically the iron-loaded native beers, provides effective long-term control.

Phenetylurea See dulcin

Polyphenol oxidase (catechol oxidase, laccase EC is a calcium-dependent enzyme responsible for browning of cut fruit and vegetables. It acts on catechols and other polyphenols, including flavonoids. Inhibited by chelating compounds such as edta, also by sulphites and cysteine. phenolphthalein See laxatives.

The Role of Tetrahydrobiopterin in Nitric Oxide Synthase

Amide Anion

Three human redox enzymes, and a variety of bacterial enzymes, contain molybdenum chelated by two sulfur atoms in a modified pterin molybdopterin (see Figure 10.1). In sulfite oxidase, the other two chelation sites of the molybdenum are occupied by oxygen in xanthine oxidase dehydrogenase (Section 7.3.7) and aldehyde oxidase, one site is occupied by oxygen and one by sulfur. In some bacterial enzymes, molybdopterin occurs as a guanine dinu-cleotide rather than free. In others, tungsten rather than molybdopterin is the chelated metal there is no evidence that any mammalian enzymes contain tungsten. As shown in Figure 10.12, four of the six chelation sites of the cobalt atom of cobalamin are occupied by the nitrogens of the corrin ring and one by the nitrogen of the dimethylbenzimidazole side chain. The sixth site may be occupied by the following ligands in biologically active vitamers

Nuclear Transplantation Reagents and Equipment

Lumbar Drain

Linearized plasmid (200-250 ng L) Although we have primarily used plasmid linearized with XbaI or NotI in transplantation reactions, we have also used Xhol, BamHI, and EagI successfully. We think that most enzymes that function in the moderately high salt conditions of the egg extract are likely to work. We commonly purify linearized plasmid for transgenesis using the Geneclean kit by Bio 101, Inc. (cat. no. 1001-200 1070 Joshua Way, Vista CA 92083 1-800-4246101). Plasmid DNA can be eluted in either dH20 or in TE (10 mM Tris-HCl, pH 8.0 1 mM EDTA). If linearized plasmid DNA needs to be concentrated, standard precipitation with 0.1 vol sodium acetate (3 M stock pH 5.2) and 2.5 vol absolute ethanol, followed by a 70 ethanol wash, can be used. We have found that plas-mid DNA purified in this manner works well for making transgenic embryos and does not adversely effect embryonic development.

System Calibration with Tissue Simulating Phantoms

We have systematically examined the impact of the properties and size of the homogeneous calibration phantom on image quality by calibrating with different homogeneous phantoms before repeatedly imaging the same heterogeneous phantom. We developed a heterogeneous phantom with a cavity that could be filled with a mixture of water, Intralipid, and blood at varying concentrations, allowing a direct measure of an object with well-established optical properties. Photographs of one heterogeneous phantom and six homogeneous calibration phantoms are shown in Figure 6. The heterogeneous phantom is 84 mm in diameter, with a single, 20 mm-diameter hole parallel to the depth-axis of the cylinder. This hole was filled with different ratios of water, Intralipid, and blood to provide a target with variable contrast. The human blood used in the experiment was kept in a 7 ml tube with liquid additive to reduce the clotting of the platelets (volume, 0.07ml of 15 solution buffered weight 10.5 mg EDTA k3...

Read that toxins can cause MS Is this true Can I be detoxified

One continuing concern is whether mercury in dental amalgam, the material used in dental fillings, is a health issue for MS. Although industrial mercury pollution was a major health problem in Japan and elsewhere, mercury in dental amalgam is a very different issue. There are inconsequential differences in serum and tissue levels of mercury in MS patients as compared with normals. We have found no differences in urinary excretion of mercury in MS patients. In studies of edentulous MS patients who had never had any dental repairs, we found they had higher levels of mercury simply because they consumed more fish. Thus, there is no medical justification for removal of amalgam dental fillings, and the concept of detoxification has no place in the management of MS. Increased excretion of metals after chelation with drugs does not mean toxic levels were present in the person prior to chelation. Many of the measurements reported by laboratories are unreliable. Hair analysis is preferred, but...

Supplementation and Fortification

Fortification of staple foods with 3-10 mg iron daily, depending on the needs of the population, is a long-term preventative strategy. In the United States, bread and cereal products are routinely fortified with 20 mg iron per pound (460 g) of flour, and additional fortification at the option of food suppliers is common. However, fortification is difficult when food processing is decentralized, as is common in poor populations. Food fortification carries the additional challenge that the chemical forms of iron most bioavailable also tend to be the most reactive with the food fortified, resulting in adverse changes in flavor, color, and shelf life. Promising approaches include the fortification of food sauces with iron chemically bound with amino acids or with EDTA (sodium iron ethylenediaminetetraacetic acid), which are well absorbed even in the presence

Human Zinc Deficiency

In addition to dietary inadequacy, there are several routes that lead to zinc deficiency. Acrodermatitis enteropathica, the genetic disorder of zinc malabsorption, has already been mentioned. Other, more generalized, malabsorption syndromes (e.g., coeliac disease) can also lead to zinc deficiency. Deficiency has also resulted from inappropriate intravenous feeding and the use of chelation therapy. Children are likely to be particularly at risk of zinc deficiency, because of its involvement in growth.

Effect of Malnutrition on the Course of Tuberculosis

In addition, anemia and hypoalbuminemia are associated with severity of the clinical course of TB. Severe anemia has been negatively correlated with the response to treatment and is associated with early mortality from TB. Anemia in TB patients may be normocytic and normochromic, or it may be microcytic and hypochromic, suggesting a relationship to iron homeostasis in some cases. Iron metabolism is disrupted in active TB. Mycobacterium tuberculosis requires iron to grow and avidly scavenges iron from its environment. One aspect of the host response to TB is intense sequestration of iron that restricts microbial growth. Whether iron supplementation or iron chelation may play a role in the treatment of TB remains speculative.

Effects of bleaching agents on enamel surface

Tezel et al (Tezel et al., 2007) claimed that the Ca2+ loss as a result of bleaching process can be named as erosion since the erosion is defined as the physical result of a pathologic, chronic and localized loss of dental hard tissue which is chemically etched away from tooth surface by acid and or chelation without bacterial involvement (Imfeld, 1996). However it should also be mentioned that with in the presence of dental plaque, the outcomes could be very different.

Complications And Prognosis

To corticosteroid therapy cataracts may develop from long-term use of these agents. Appropriate management of these complications provides the best opportunity for avoiding adverse visual outcomes. Band keratopathy is a complication specifically associated with JRA and is treated by chelation and excimer laser (Fig. 1D). CME is the most common cause of decreased visual acuity in patients with posterior uveitis (Fig. 1E). Finally, other complications may result from systemic treatments (1,14,16).

Subtractive Hybridization

Prepare first-stranded target cDNA (see Note 17) from poly (A)+ mRNA as described above (preferred) or in vitro sense RNA derived from a target cDNA library. In the latter case one should use 5 pg of random hexamers as primers, since one cannot be sure that the poly A tail is present after XhoI digestion. Remove the RNA by adding 10 pL of 0.25 M EDTA and 30 pL 0.15 N NaOH, and incubating for 60 min at 65 C. Neutralize with 30 pL of 0.15 N HCl, ethanol-precipitate, rinse, and dry. 4. Short hybridization spin an appropriate amount of biotinylated driver RNA precipitate (10-fold molar excess to the cDNA) rinse and dry it. Resuspend the RNA in 20 pL of hybridization buffer (HBS 50 mM HEPES, pH 7.6, 0.2 SDS, 2 mM EDTA, 500 mM NaCl).

Postantibody Washes and Histochemistry

For in situ hybridizations using a single probe, stop the reaction by washing thoroughly in PBT containing 20 mM EDTA or in 1X TBST. Refix in 4 paraform-aldehyde prior to storing at 4 C or sectioning. Embryos can also be stored at 4 C in autoclaved 90 v v glycerol, 1X PBS.

Isolation of Primordial Germ Cells

Tissue-culture reagents can be purchased from Grand Island Biological Company (Gibco, Grand Island, NY, 1-800-828-6686). Trypsinization solution is 0.25 trypsin, 1 mM EDTA in Hank's balanced salts (cat. no. 25200-056). Dulbecco's phosphate-buffered saline (PBS) is 0.2 g L KCl, 0.2 g L KH2PO4, 8 g L NaCl, 1.15 g L Na2HPO4, and 2.16 g L Na2HPO47H2O. (cat. no. 14190). Medium is Dulbecco's Modified Eagle's Medium (DMEM) supplemented with 4.5 g L glucose (cat. no. 11965-084). For the culture of PGCs, this medium is further supplemented with 0.01 mM nonessential amino acids (cat. no. 11140-019), 2 mM glutamine (cat. no. 25030-016), 50 g mL gentamycin (cat. no. 15750-011), 0.1 mM 2-mercaptoethanol (cat. no. 21985-023), and 15 fetal bovine serum (ES cell tested, from either Summit Biotechnology, Fort Collins, CO, 1800-933-0909 or HyClone Laboratories, Logan, UT, 1-800-492-5663). For the routine culture of fibroblast feeder cells, the DMEM with glucose is supplemented with 10 fetal bovine...

Of Cholesterol Gallstone Formation

Simple modifications of the curcumin structure raise the IC50 value, but complexes of the central dihydroxy groups of curcumin with boron lower the IC50 to a value as low as 6 am. The boron complexes are also time-dependent inactivators of the HIV proteases. The increased affinity of the boron complexes may reflect binding of the orthogonal domains of the inhibitor in interesecting sites within the substrate-binding cavity of the enzyme, while activation of the a,h-unsaturated carbonyl group of curcumin by chelation to boron probably accounts for time-dependent inhibition of the enzyme.

Bioavailability Of Fortified Wheat Flour

Trace element interactions are generally antagonistic, and when two chemically similar ions are present in the intestinal lumen, the one with a greater ratio tends to exclude the other. The ingestion of excess amounts of zinc induces anemia and depresses tissue iron levels in rats and chicks (Bafundo et al., 1984), but this interaction has received little attention with regard to humans. Previous studies have reported a variety of results concerning the interactive effect of dietary minerals on the iron content of organs and tissues. NaFeEDTA is thought to be highly bioavailable, and iron in it is chelated with EDTA, a commonly used food additive that prevents the iron from being bound with phytic acid. NaFeEDTA is better absorbed and not sensitive to many food iron inhibitors compared with other iron fortificants. The lower bioavailability of elemental iron compared to that of NaFeEDTA has been confirmed (Hurrell, 2002 Viteri etal., 1995).

Mechanistic Studies Of Electroporation

The influence of electrode configuration on the electric field distribution has been shown by measuring 51Cr-EDTA uptake in vivo (19,20). These studies indicated two uptake phases in which the membrane permeabilization increases, followed by irreversible membrane damage. Both plate electrodes (18,21) or a pair of wire electrodes (22) have been shown to be effective. The calculated electric field distribution was more homogenous for plate electrodes than for needle electrodes. Also, the needle diameter determines 3 parameters in rabbit liver, the decrease of the electric field intensity near the electrodes is steeper with smaller electrode diameter the area covered with a given electric field is smaller with smaller electrodes (23) and there is a more homogenous electric field with larger electrode diameter.


In one study of dialysis patients, correlations were sought between cognitive function and exposure to aluminum in both dialysis source water and administered oral gut phosfate binders. The results of the study were confusing since it found negative correlations between the cognitive measures and source water aluminum but positive correlations with the level of orally administered phosfate binder. Again, in a gold miner study, some results indicated cognitive impairment, whereas others were less conclusive. It has been noted that most studies performed to date are flawed, because they have failed to include normal aging controls. Attempts to improve cognitive scores by chelation therapy have met with very limited success. concentrations greater than 200 mgl-1. At these centers, the prevalence of the disease increased significantly with increasing cumulative exposure to aluminum and was often a direct cause of death. In terminal cases, facial grimacing, myotonic spasms, and dysphagia...

First catch your DNA

Ethylenediamine tetra-acetate (EDTA) sodium dodecyl sulfate (SDS) phenol (carbolic acid) Method 4. Add a drop or two of EDTA and SDS. Between them, these two chemicals break open the bacterial cell walls and release all the cell contents. (EDTA weakens the cell walls by removing their magnesium ions while SDS is a detergent-like chemical that dissolves the fat molecules in the cell walls.) After about 30 minutes you should have a clear, viscous quid the consistency of egg white.


Anticopper therapies may be useful in cancer treatment because cancer cells require copper for survival. For example, copper-deficient diets inhibited the growth of brain cancer cells in rats.119,120 Copper is also needed for angiogenesis, and copper-deficient diets, copper-chelating agents, or other forms of anticopper therapy can inhibit angiogenesis in rats, rabbits, and humans (see Chapter 8). As with iron, however, a certain level of copper is necessary to sustain life. Thus an optimum

Cation ic effect

LF was found to contain an antimicrobial sequence near its N-terminus, which appears to function by a mechanism distinct from iron chelation. The identified domain contains a high proportion of basic residues, like various other antimicrobial peptides known to target microbial membranes and it appears to be located on the surface of the folded protein allowing its interaction with surface components of microbial cells (Tomita et al., 1994).

Ion Exchange Methods

Because of its simplicity and low cost, ion exchange chromatography is often used for processing a large number of samples, though it is not a rapid procedure. Smith and Clarke 2 introduced the technique for separation of in-ositol phosphates using a stepwise elution with HCl. About 10 years later, an HCl gradient for qualitative analysis of phosphate esters was used by Cosgrove 3 . Since Harland and Oberleas in 1977 29 introduced an anion exchange chromatography method with step gradient elution for quantification of InsP6, several modifications to this method have been published 23,30-32 . The eluate is digested, inorganic phosphorus is measured, and InsP6-equivalent is calculated. The InsP6 value from the iron-precipitation method was indicated to be higher than values from the ion exchange method 33 . Ellis and Morris 30 suggested that substances in the acid extract were interfering with InsP6, resulting in the lower values. If EDTA was added to the sample extract and the pH was...

Detection Methods

Many species that are not chromophoric or fluorophoric can be post-column derivatized to form complexes that are detectable by UV, visible absorbance, or fluorescence monitoring. Phosphate groups can be derivatized by Fe3+ to form complexes for UV detection 50 . This principle has been used for InsP6 and other inositol phosphates 16,20,36,44 . Irth and coworkers 51 used a post-column reaction detection system based on ligand exchange between phosphate ions and an Fe3+-methylcalcein blue (MCB) reagent for fluorescence detection of Ins(1,2,6)P3. Small and Miller Jr. 52 first introduced indirect photometric chromatography (IPC), a technique that may be used to overcome the problem of UV transparency. The principle of IPC is the use of eluent containing light absorbing (usually UV) ions that displace the sample ions from the column, resulting in negative peaks in the baseline absorbance. The technique was first used for InsP6 determination in 1988 53 , although the sensitivity was quite...

Induction agents

Bacterial growth is inhibited by ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DPTA), sulfite, or benzyl alcohol depending on the manufacturer (don't use opened propofol after 6 hours to prevent inadvertent bacterial contamination). Mode of action facilitation inhibitory neurotransmission by enhancing the function of GABAa receptors in the central nervous system the modulation of glycine receptors, N-etyl-D aspartate receptors, cannabinoid receptors and voltage-gated ion channels may also contribute to propofol's actions. After the infusion it can be observed dose-dependent decreases in preload, afterload and contractility that lead to decrease in blood pressure and cardiac output. Hypotension may be marked in hipovolemic, elderly, or hemodynamically compromised patients. Heart rate is minimally affected and baroreceptor reflex is blunted. Adverse effects are venous irritation, lipid disorders, myoclonus and hiccups, propofol infusion...

EDTA As is indicated in Table 13.2 a number of disease states have been associated directly with changes in the concentrations of trace metals in tissues and body fluids. Drugs whose modus operandi is through electron donation may well complex metals, either as their central mechanism or as a side effect. Similarly chelating agents have been used as drugs designed specifically to sequester metals, especially toxic ones such as those shown in Table 13.4, and to mobilise metals from labile protein complexes into low molecular mass forms. Invariably the matching of ligands to metals is in keeping with the principles of the HSAB concept.


Some of the agents a homeopath might recommend would include diluted amounts of mercurius vivus, causticum, argentum nitricum, and zincum metallicum. Tremor might be treated with anthimonium tartaricum, mercurius corrosivus, and agaricus. Rigidity and tremor would likely be treated with rhus toxicodendron, and fatigue, weakness, and staggering gait might be treated with gelsemium. These are typically prescribed in a liquid form or in pellets that are dissolved in water and taken several times daily until the motor symptoms improve. There are no published controlled or open label studies indicating the benefit of homeopathic remedies for the treatment of PD and similar to chelation therapy, homeopathy is not accepted or recommended as a treatment for PD.

Ellison et al. (1990) studied the ability of LF and TF to damage the Gram-negative outer membrane. Lipopolysaccharide (LPS) release by the proteins could be blocked by concurrent addition of Ca2+ and Mg2+. Addition of Ca2+ also blocked the ability of LF to increase the susceptibility of i , coli to rifampicin. TF, but not LF, increased susceptibility of Gram-negative bacteria to deoxycholate, with reversal of sensitivity occurring with exposure to Ca2+ or Mg2+. In transmission electron microscopy studies polymyxin B caused finger-like membrane projections, but no morphological alterations were seen in cells exposed to EDTA, LF or TF. These data provide further evidence that LF and TF act as membrane-active agents with the effects modulated by Ca2+ and Mg2+.

2 ml peripheral blood was collected into ethylenediaminetetraacetic acid (EDTA)-anticoagulated tubes by the standard venipuncture method and DNA was extracted using the QIAamp DNA Blood Isolation kit (Qiagen GmbH, Hilden, Germany) following the manufacturer's instructions. The extracted DNA concentration was determined using a Thermo Scientific NanoDrop spectrophotometer (Wilmington, USA). The quality assessment of the extracted DNA was determined by 2 agarose gel electrophoresis.


Chelation-related drug interactions have been evaluated with concomitant use of ciprofloxacin and iron glucanoate, iron sulfate, magnesium aluminum-containing antacids, sucralafate, zinc, calcium carbonate, calcium acetate, bismuth subsalicylate, and sevelamer. Simultaneous administration of iron, magnesium, aluminum, and zinc can result in 50 to 90 reduction in both the Cmax and AUC of oral ciprofloxacin 5-7,25 . In contrast, a 30 to 40 reduction in Cmax and AUC can occur with coadministration of ciprofloxacin and calcium or sevelamer 6,25 . Bismuth interacts minimally (10 reduction in AUC) with ciprofloxacin 25 . Coadministration of these agents 2 hours prior to or 6 hours after the administration of ciprofloxacin reduces this interaction and is the manufacturer-recommended approach 26 . Most drug interactions of tetracyclines are pharmacokinetic and reflect changes in absorption and elimination of this drug class or other agents (Table 2). The plasma concentrations of tetracyclines...


An example of an effect of a nutrient on translation of a specific mRNA is that of iron in the synthesis of ferritin. Iron storage in cells occurs through chelation to a protein called ferritin. Ferritin synthesis is highly regulated by iron intake. In iron deficiency, the mRNA start site for ferritin translation is obstructed by an iron regulatory protein. This protein binds to the 5' untranslated region and inhibits the movement of the 40s ribo-some from the cap to the translation start site. When the diet contains sufficient iron and iron status is improved, the iron regulatory protein dissociates from the ferritin mRNA and translation proceeds. When iron availability is limited, the same iron regulatory protein binds to ferritin mRNA (to inhibit its translation) and to the trans-ferrin receptor mRNA, as described previously (to prevent its degradation and ensure its translation). These exquisite mechanisms serve to maintain iron homeostasis.


Insufficient controlled clinical trials have been performed to make clear-cut recommendations for pharmacotherapy for toxicity from either nickel or bismuth. Diethyl dithiocarbamide chelation therapy when promptly administered intravenously has been reported to be effective in acute nickel carbonyl poisoning. In addition, there have been anecdotal case reports of the reversal of myoclonic encephalo-pathy caused by bismuth with use of dimercaprol. However, no recommendations can be given at the present time.
