Effect of shellfish calcium on the apparent absorption of calcium and bone metabolism in ovariectomized rats. (1/1204)

Fossil shellfish powder (FS) and Ezo giant scallop shell powder (EG) were rendered soluble with lactate and citrate under decompression (FSEx and EGEx, respectively) and we examined the effects of lactate-citrate solubilization of FS and EG on mineral absorption, tissue mineral contents, serum biochemical indices and bone mineral density (BMD) in ovariectomized (OVX) rats. The apparent absorption ratios of minerals tended to be high in the rats fed with the solubilized mineral sources, those in the FSEx group being significantly higher than in the FS group. There was no significant difference in the tibia mineral content among the OVX groups. BMD at the distal femoral diaphysis was significantly increased by FSEx and EGEx feeding. It is suggested that solubilization with lactate and citrate under decompression increased the solubility and bioavailability of calcium from such natural sources of shellfish calcium as FS and EG.  (+info)

Down regulation by iron of prostaglandin E2 production by human synovial fibroblasts. (3/1204)

OBJECTIVE: To examine the effect of iron on the prostaglandin (PG) E2 production by human synovial fibroblasts in vitro. METHODS: Human synovial fibroblasts were isolated from synovial tissue of rheumatoid arthritis (RA) and osteoarthritis (OA) patients and cultured in medium. Synovial fibroblasts were stimulated by human recombinant interleukin (IL) 1 beta (0.1-10 ng/ml) with or without ferric citrate (Fe-citrate, 0.01-1 mM). The amount of PGE2 in the culture medium was measured by an enzyme linked immunosorbent assay. RESULTS: The production of PGE2 by the synovial fibroblasts was increased by stimulation with IL1 beta at all concentrations tested. Fe-citrate but not sodium citrate (Na-citrate) down regulated the production of PGE2 by the synovial fibroblasts, both with and without stimulation by IL1 beta. Fe-citrate inhibited the spontaneous PGE2 production by the cells in a dose dependent manner, and a maximum inhibition by Fe-citrate was observed at the concentration of 0.1 mM with IL1 beta stimulation. The down regulation by iron was reversed by the co-addition of desferrioxamine (100 micrograms/ml), an iron chelator. CONCLUSION: Iron down regulates the PGE2 production by synovial fibroblasts in vitro.  (+info)

Roles of oxygen radicals and elastase in citric acid-induced airway constriction of guinea-pigs. (4/1204)

Antioxidants attenuate noncholinergic airway constriction. To further investigate the relationship between tachykinin-mediated airway constriction and oxygen radicals, we explored citric acid-induced bronchial constriction in 48 young Hartley strain guinea-pigs, divided into six groups: control; citric acid; hexa(sulphobutyl)fullerenes + citric acid; hexa(sulphobutyl)fullerenes + phosphoramidon + citric acid; dimethylthiourea (DMTU) + citric acid; and DMTU + phosphoramidon + citric acid. Hexa(sulphobutyl)fullerenes and DMTU are scavengers of oxygen radicals while phosphoramidon is an inhibitor of the major degradation enzyme for tachykinins. Animals were anaesthetized, paralyzed, and artificially ventilated. Each animal was given 50 breaths of 4 ml saline or citric acid aerosol. We measured dynamic respiratory compliance (Crs), forced expiratory volume in 0.1 (FEV0.1), and maximal expiratory flow at 30% total lung capacity (Vmax30) to evaluate the degree of airway constriction. Citric acid, but not saline, aerosol inhalation caused marked decreases in Crs, FEV0.1 and Vmax30, indicating marked airway constriction. This constriction was significantly attenuated by either hexa(sulphobutyl)fullerenes or by DMTU. In addition, phosphoramidon significantly reversed the attenuating action of hexa(sulphobutyl)fullerenes, but not that of DMTU. Citric acid aerosol inhalation caused increases in both lucigenin- and t-butyl hydroperoxide-initiated chemiluminescence counts, indicating citric acid-induced increase in oxygen radicals and decrease in antioxidants in bronchoalveolar lavage fluid. These alterations were significantly suppressed by either hexa(sulphobutyl)fullerenes or DMTU. An elastase inhibitor eglin-c also significantly attenuated citric acid-induced airway constriction, indicating the contributing role of elastase in this type of constriction. We conclude that both oxygen radicals and elastase play an important role in tachykinin-mediated, citric acid-induced airway constriction.  (+info)

Citrate ions enhance taste responses to amino acids in the largemouth bass. (5/1204)

The glossopharyngeal (IX) taste system of the largemouth bass, Micropterus salmoides, is highly selective to amino acids and is poorly responsive to trisodium citrate; however, IX taste responses to specific concentrations of L- and D-arginine and L-lysine but not L-proline were enhanced by citrate but not sodium ions. Binary mixtures of L-arginine (3 x 10(-4)M and 10(-3)M) or D-arginine (10(-3)M) + trisodium citrate (10(-3)M; pH 7-9) resulted in enhanced taste activity, whereas binary mixtures of higher concentrations (10(-2)M and 10(-1)M) of L- or D-arginine + 10(-3)M trisodium citrate were not significantly different from the response to the amino acid alone. Under continuous adaptation to 10(-3)M citrate, taste responses to L-arginine were also enhanced at the identical concentrations previously indicated, but responses to 10(-2)M and 10(-1)M L-arginine were significantly suppressed. Under continuous adaptation to 10(-2)M L-arginine, taste responses to 10(-2)M, 10(-1)M, and 10(0) M citrate were significantly enhanced. Cellular concentrations of both citrate and amino acids in prey of the carnivorous largemouth bass are sufficient for this taste-enhancing effect to occur naturally during consummatory feeding behavior. Citrate acting as a calcium chelator is presented as a possible mechanism of action for the enhancement effect.  (+info)

Trophoblast cell line resistance to NK lysis mainly involves an HLA class I-independent mechanism. (6/1204)

The lack of classical HLA molecules on trophoblast prevents allorecognition by maternal T lymphocytes, but poses the problem of susceptibility to NK lysis. Expression of the nonclassical class I molecule, HLA-G, on cytotrophoblast may provide the protective effect. However, the class I-negative syncytiotrophoblast escapes NK lysis by maternal PBL. In addition, while HLA-G-expressing transfectants of LCL.721.221 cells are protected from lymphokine-activated killer lysis, extravillous cytotrophoblast cells and HLA-G-expressing choriocarcinoma cells (CC) are not. The aim of this work was therefore to clarify the role of HLA class I expression on trophoblast cell resistance to NK lysis and on their susceptibility to lymphokine-activated killer lysis. Our results showed that both JAR (HLA class I-negative) and JEG-3 (HLA-G- and HLA-Cw4-positive) cells were resistant to NK lysis by PBL and were equally lysed by IL-2-stimulated PBL isolated from a given donor. In agreement, down-regulating HLA class I expression on JEG-3 cells by acid treatment, masking these molecules or the putative HLA-G (or HLA-E) receptor CD94/NKG2 and the CD158a/p58.1 NKR with mAbs, and inducing self class I molecule expression on JAR cells did not affect NK or LAK lysis of CC. These results demonstrate that the resistance of CC to NK lysis mainly involves an HLA class I-independent mechanism(s). In addition, we show that the expression of a classical class I target molecule (HLA-B7) on JAR cells is insufficient to induce lysis by allospecific polyclonal CTL.  (+info)

Regional citrate anticoagulation in continuous venovenous hemofiltration in critically ill patients with a high risk of bleeding. (7/1204)

BACKGROUND: Systemic heparinization is associated with a high rate of bleeding when used to maintain patency of the extracorporeal circuit during continuous renal replacement therapy (CRRT) in critically ill patients. Regional anticoagulation can be achieved with citrate, but previously described techniques are cumbersome and associated with metabolic complications. METHODS: We designed a simplified system for delivering regional citrate anticoagulation during continuous venovenous hemofiltration (CVVH). We evaluated filter life and hemorrhagic complications in the first 17 consecutive patients who received this therapy at our institution. Blood flow rate was set at 180 ml/min. Ultrafiltration rate was maintained at 2.0 liters/hr and citrate-based replacement fluid (trisodium citrate 13.3 mM, sodium chloride 100 mM, magnesium chloride 0.75 mM, dextrose 0.2%) was infused proximal to the filter to maintain the desired fluid balance. Calcium gluconate was infused through a separate line to maintain a serum-ionized calcium level of 1.0 to 1.1 mM. RESULTS: All patients were critically ill and required mechanical ventilation and vasopressor therapy. Systemic heparin anticoagulation was judged to be contraindicated in all of the patients. A total of 85 filters were used, of which 64 were lost because of clotting, with a mean life span of 29.5 +/- 17.9 hours. The remaining 21 filters were discontinued for other reasons. Control of fluid and electrolyte balance and azotemia was excellent (mean serum creatinine after 48 to 72 hr of treatment was 2.4 +/- 1.2 mg/dl). No bleeding episodes occurred. Two patients, one with septic shock and the other with fulminant hepatic failure, developed evidence for citrate toxicity without a significant alteration in clinical status. Nine patients survived (52.9%). CONCLUSION: Our simplified technique of regional anticoagulation with citrate is an effective and safe form of anticoagulation for CVVH in critically ill patients with a high risk of bleeding.  (+info)

Comparative absorption of calcium sources and calcium citrate malate for the prevention of osteoporosis. (8/1204)

Anthropologically speaking, humans were high consumers of calcium until the onset of the Agricultural Age, 10,000 years ago. Current calcium intake is one-quarter to one-third that of our evolutionary diet and, if we are genetically identical to the Late Paleolithic Homo sapiens, we may be consuming a calcium-deficient diet our bodies cannot adjust to by physiologic mechanisms. Meta-analyses of calcium and bone mass studies demonstrate supplementation of 500 to 1500 mg calcium daily improves bone mass in adolescents, young adults, older men, and postmenopausal women. Calcium citrate malate has high bioavailability and thus has been the subject of calcium studies in these populations. Positive effects have been seen in prepubertal girls, adolescents, and postmenopausal women. The addition of trace minerals and vitamin D in separate trials has improved the effect of calcium citrate malate on bone density and shown a reduction of fracture risk.  (+info)

Citric acid is found naturally in citrus fruits, but producing citric acid from citrus fruits is very expensive and the demand for citric acid is greater than the available supply of citrus fruits. Therefore, when you see citric acid on a product label, you can be sure that it is a powder that was made from the fermentation of sugars. A culture of Aspergillus niger (a fungus commonly used in the pharmaceutical industry) is fed with sugar and metabolizes it into a liquid solution. The solution is mixed with lime (calcium hydroxide) which causes citrate salt to come out of the solution (precipitate). The citrate salt is then treated with sulfuric acid to make useable citric acid.. The sugars that are used for the citric acid can be derived from cane sugar, corn or wheat. In the United States, citric acid is most often derived from corn since it is a cheap, subsidized crop. In South America cane sugar is often used due to the low sugar prices, while in Europe wheat sweeteners are commonly ...

Citric acid is traditionally produced by fermentation of molds since the beginning of the 20th century. However, its overall demand continually increases due to its very widespread applications ranging from traditional food use to more specific pharmaceutical and more recent biopolymer uses.. Therefore the production of citric acid is also continually improved involving the most recent tools and techniques of the field. This book discusses the metabolism of citric acid production by Aspergillus niger; biotechnological productions of citric acid; citrus fruits compounds and aging; occurrence and metabolism of citric acid by lactic acid bacteria from fruits and fermented beverages; and citric acid treatment of cancer. (Imprint: Novinka ). ...
Citric acid -- a naturally occurring compound in citrus fruits such as oranges, lemons and grapefruit -- boasts several properties that may make it useful as either a treatment for certain medical conditions or as a dietary supplement. Citric acid is an alkalizing agent: It is able to decrease the level of acidity in body fluids. It acts as an anti-oxidant and is also able to chelate -- binding to excess calcium and allowing it to leave the body. Despite its documented health benefits, you should not take citric acid supplements without first consulting your physician.. Anti-oxidant Benefits. As an anti-oxidant, citric acid may be able to neutralize the damaging effects of free radicals, unstable compounds that can accumulate in the body from exposure to toxic chemicals, smoking and even normal cell metabolism. Free radicals can damage cell tissue and DNA and increase the risk of developing cardiovascular disease, Alzheimers disease and cancer. The Mayo Clinic website reports that citric acids ...
Citric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/l in the juices[9]).[a] The concentrations of citric acid in citrus fruits range from 0.005 mol/L for oranges and grapefruits to 0.30 mol/L in lemons and limes; these values vary within species depending upon the cultivar and the circumstances in which the fruit was grown. Industrial-scale citric acid production first began in 1890 based on the Italian citrus fruit industry, where the juice was treated with hydrated lime (calcium hydroxide) to precipitate calcium citrate, which was isolated and converted back to the acid using diluted sulfuric acid.[10] In 1893, C. Wehmer discovered Penicillium mold could produce citric acid from sugar. However, microbial production of citric acid did not become industrially important until World War I ...
Any non-trial optimisation design could only be accomplished from a consistent picture of the mycelial physiology. In this work, we have made progress on the understanding of the biochemical basis of the citric acid producing strain of Aspergillus niger using afed-batch cultivation system. This optimisation would imply the improvement of both, the citric acid synthesis and excretion rate. For citric acid fermentation, trace elements such as copper, managanese, iron, zinc and molybdenum are needed in ppm for optimum growth (Netik et al. 1997), but the concentration will depend on the carbon source used and temperature of incubation. The data in Table 1 show the screening of the best available stock cultures of Aspergillus niger for citric acid production in an agitator bioreactor. The range of citric acid was 54.50-87.98 g/l. The culture NGGCB101 (developed by UV/Chemical mutation in our labs) gave maximum yield of the product (87.98 g/l) followed by Zowang-12 (84.20 g/l) and NIAB-280 (79.40 ...
In this study, a glycerol which is a common biodiesel byproduct was used to produce citric acid by fermentation using strains of Aspergillus niger. The culture medium contained glycerol as the carbon source, yeast extract as the nitrogen source and KHzP04 and Na2HP04 as the phosphate source as well as other essential nutrients for the fungae. The parameters studied were incubation temperature, nitrogen content, phosphate content and addition of additive. Eight experiments were done to determine the most optimum conditions. Titration of the product citric acid with 0.1 M NaOH was done to obtain the concentration and yield of citric acid of all experiments. The result obtained proved that citric acid production was most optimum when the incubation temperature was at 30°C, nitrogen contents at 0.01 to 0.04 g per 100 m1 and the phosphate content at 0.7 g per 100ml. Also when ethanol at 3.0 % v/w was used as an additive in the medium the yield of citric acid increased. Experiment eight with the ...

Citric acid (citrate) is a weak acid that is formed in the tricarboxylic acid cycle or that may be introduced with diet. The evaluation of plasma citric acid is scarcely used in the diagnosis of animal diseases. On the contrary urinary citrate excretion is a common tool in the differential diagnosis of kidney stones, renal tubular acidosis and it plays also a role in bone diseases. The importance of hypocitraturia should be considered with regard to bone mass, urine crystallization and urolithiasis.

The present study examined whether infants show an acceptance for extreme sour tastes and whether acceptance of sour taste is related to infants fruit intake. Fruit intake of fifty-three infants at 6, 12 and 18 months was assessed using 3 d food records. Sour acceptance of these infants was studied at 18·1 (sd1·5) months. Acceptance for four solutions differing in citric acid concentrations (0·00 m, 0·013 m, 0·029 m and 0·065 m) was measured by allowing infants ad libitum ingestion of each solution over brief time periods. The base solution to which citric acid was added was blackcurrant squash diluted in water. Infants relative intake of each solution was used as a measure of sour acceptance. At 18 months, twelve infants readily accepted the two highest citric acid concentrations, whereas the remaining infants rejected these. Infants who accepted the most sour solutions had a significantly higher fruit intake (P = 0·025) and a higher fruit variety (P = 0·015) at 18 months than the ...

In this study we investigated the transcriptional role of the sterol regulatory element (SRE) present in the promoter of the mitochondrial citrate carrier (CIC). We show that wild-type (but not mutated) CIC SRE cloned in front of the luciferase promoter confers transcriptional activation of the gene reporter. We also demonstrate that insulin activates, and polyunsaturated fatty acids (PUFA) inhibit, the gene reporter activity driven by the CIC promoter containing wild-type (but not mutated) SRE. Finally, both insulin treatment and overexpression of SRE binding protein (SREBP-1) increase the CIC transcript and protein levels, whereas PUFA have an opposite effect. These results show that SRE/SREBP-1 play a role in the transcriptional regulation of CIC by insulin and PUF. ...

The positive results obtained with regional citrate anticoagulation were confirmed in 3 recently published large studies involving 251 patients (9,31,38). In the prospective randomized study by Kutsogiannis DJ et al (38) involving 30 patients not at high risk of hemorrhagic complications, the median hemofilter survival time was 124.5 hours in the citrate group, the time being significantly longer than the 38.3 hours in the heparin group (P , 0.001). As regards adverse effects, no definite hemorrhage occurred in the citrate group whereas seven instances did in the heparin group. Occult hemorrhage was once present in both the citrate and heparin group. After adjustment for antithrombin-III levels and illness severity score, the relative risk of hemorrhage with citrate anticoagulation was still significantly lower than that with heparin (0.14 vs 0.96). In the second considered large multi-center study involving seven US centers, 138 patients and 442 CRRT circuits were utilized to assess filter life ...

In this series, blood and urinary tests confirmed the usual features of FHHNC (15) in CLDN19 patients: (1) persistent hypomagnesemia unresponsive to Mg2+ administration, (2) thiazide-sensitive hypercalciuria with normal serum Ca2+ levels and a slightly increased parathormone level, (3) low urinary citrate excretion, and (4) progressive renal failure leading to ESRD. However, one can note some peculiar renal findings. First, although FHHNC is mostly diagnosed during the first years of life (age of diagnosis within the first decade for all patients, within the first year of life for 8 of 12 patients) (5), it can be asymptomatic until the end of the second decade as exemplified by patient F2.3. In patients with CLDN16-related FHHNC, a genotype-phenotype correlation has been established and age at onset and severity may be predicted from the CLDN16 genotype (12). Because of the recent recognition of CLDN19 mutations in humans and their low frequency, this analysis has not yet been performed in ...

Calcium citrate malate is a water-soluble calcium supplement. It is the calcium salt of citric acid and malic acid with variable composition. Calcium citrate malates bioavailability stems from its water-solubility and its method of dissolution. When dissolved, it releases calcium ions and a calcium citrate complex. Calcium ions are absorbed directly into intestinal cells, and the citrate complex enters the body through paracellular absorption.[citation needed] Calcium citrate malate is similar to calcium malate and other calcium salts. The European Food Safety Authority has concluded that calcium citrate malate is slightly more bioavailable than other forms of calcium supplementation.

Lead citrate is a key precursor for the green recycling of spent lead acid battery paste in a citric acid/sodium citrate (CA/SC) solution. In this study, the main paste component, PbSO4, was leached and crystallized to yield lead citrate. Results showed that the leaching of PbSO4 in citric acid/sodium citrate solution was remarkably enhanced by an increase in temperature from 35 °C to 95 °C and an increase in sodium citrate (SC) concentration from 50 to 650 g/L. In comparison, increasing the citric acid/sodium citrate molar ratio inhibited this leaching. Controlled crystallization through cooling the solution or adjusting the pH of the solution can effectively produce lead citrate crystals. The X-ray diffraction patterns of four products obtained in a comparison test were all consistent with Pb3(C6H5O7)2. However, the scanning electron microscopy analysis suggested that the morphology was distinct from rods to sheets, which were mainly affected by the temperature variation.

The superior ability of citrate excretion in a carrot (Daucus carota L.) mutant cell line, namely IPG (insoluble phosphate grower) [Takita et al. (1999a) Plant Cell Physiol. 40: 489] cells has been characterized in terms of citrate transport at the plasma membrane. IPG cells released about a 20-fold increase in citrate in comparison with malate, while the concentration of malate was only 35% lower than that of citrate in the cell sap. Citrate excretion was sensitive to anion channel blockers, such as niflumic acid and anthracene-9-carboxylic acid. These results indicate that IPG cells release citrate through the plasma membrane using citrate specific anion channels. The rate of citrate release from IPG cells was not affected by the concentration of aluminum (0 and 50 µM), soluble Pi (0 or 2 mM) and the pH (4.5-5.6) of the medium, suggesting that anion channels would not be regulated by such external conditions. Citrate excretion correlated with the H+ efflux, possibly from the action of ...

Y1 - 2007/3. N2 - Background: Regional citrate anticoagulation (RCA) is an effective form of anticoagulation for continuous renal replacement therapy (CRRT) in patients with contraindications to heparin. Its use has been very limited, possibly because of the need for special infusion solutions and difficult monitoring of the metabolic effects. Objective: To investigate the safety and the feasibility of an RCA method for continuous veno-venous hemofiltration (CVVH) using commercially available replacement fluid. Methods: We evaluated 11 patients at high risk of bleeding, requiring CVVH. RCA was performed using commercially available replacement fluid solutions to maintain adequate acid-base balance. We adjusted the rate of citrate infusion to achieve a post-filter ionized calcium concentration [iCa] 250 ...
The citrate-induced desorption kinetics of pre-adsorbed Se from montmorillonite (Mt) and its complexes with hydroxyaluminum (HyA-Mt) and hydroxyaluminosilicate (HAS-Mt) were studied. The mole fraction of pre-adsorbed Se released in 24 h from different clays followed the trends of Mt ,, HAS-Mt , HyA-Mt with a significant increase with elevated citrate concentration in the desorbing solution. In contrast, the amount of Se adsorbed per unit mass of different clays followed a clear-cut opposite trend of HyA-Mt , HAS-Mt ,, Mt. The Se desorption kinetics in different systems indicated multiple rate characteristics; where an initial fast reaction (0.25-2 h) was followed by a slow reaction (2-16 h). Of the six different kinetic models tested (zero-, first-, and second-order; power function, Elovich, and parabolic diffusion), the second-order rate equation showed the overall best fit to the fast and slow desorption kinetic data from the clays. Based on second-order rate constants, the rates of the mole ...

Calcium Citrate Malate is a readily-soluble form of calcium which is an easily absorbed and well-tolerated form of calcium. Calcium is an essential mineral required for healthy bone formation. Calcium bound to natural fruit acids called citric acid and malic acid results in the calcium compound, Calcium Citrate Malate. This form of calcium has been shown to have a superior benefit compared to many calcium supplements as it allows for 40% more calcium absorption than calcium carbonate or milk. Calcium Citrate Malate is easily digested and absorbed equally well with or without food.. Calcium is the basic bone-building mineral required by the body. Adequate calcium intake every day, over a lifetime, is important for maintaining sufficient bone density as we age and reducing risk for osteoporosis, a progressive bone disease leading to fragile, porous bones. Risk for osteoporosis is also influenced by age, sex, race, exercise, and many other dietary and lifestyle choices. Calcium Citrate Malate is ...

Introduction. Aim: The aim on my investigation is to find the percentage of citric acid present in lemon squash by using a method of neutralisation, by a method of titration and volumetric analysis. I will be using sodium hydroxide as an alkali, which will be neutralising the citric acid. Background Knowledge: Titration Titration is a technique for investigating the volume of solutions that react together. One solution is placed in a burette and slowly added to a fixed volume of another solution, usually measured with a pipette, until the end point of the reaction is shown using an indicator. Salts can be made by this method by repeating the titration between an acid and alkali using previously measured quantities without using the indicator.

Mixed with sodium hydrogencarbonate (commonly knows as bicarbonate of soda) and sugar, it becomes ...
Abstract: CuO-ZnO-ZrO2 (CZZ) catalysts for methanol synthesis from CO2 hydrogenation were prepared by a citric acid combustion method. The combustion reactions were analyzed in terms of propellant chemistry and the combustion behavior was recorded by thermo-gravimetric/differential thermal analysis (TG-DTA). The as-prepared CZZ powders were investigated with X-ray diffraction (XRD), N2 adsorption, temperature-programmed reduction (TPR), and reactive N2O adsorption techniques and the catalytic activities were evaluated for methanol synthesis from CO2 hydrogenation. The results show that the influence of citric acid quantity on the physicochemical and catalytic properties of CZZ is subtle, and the reason is related to the characteristics of the combustion reaction. Furthermore, the relationship between the quantity of fuel (citric acid, urea, and glycine) and the properties of the catalysts was determined. The citric acid combustion method exhibits better controllability and it is a simple, fast, ...

Several catabolic pathways converge on the citric acid cycle. Most of these reactions add intermediates to the citric acid cycle, and are therefore known as anaplerotic reactions, from the Greek meaning to fill up. These increase the amount of acetyl CoA that the cycle is able to carry, increasing the mitochondrions capability to carry out respiration if this is otherwise a limiting factor. Processes that remove intermediates from the cycle are termed cataplerotic reactions. In this section and in the next, the citric acid cycle intermediates are indicated in italics to distinguish them from other substrates and end-products. Pyruvate molecules produced by glycolysis are actively transported across the inner mitochondrial membrane, and into the matrix. Here they can be oxidized and combined with coenzyme A to form CO2, acetyl-CoA, and NADH, as in the normal cycle.[35]. However, it is also possible for pyruvate to be carboxylated by pyruvate carboxylase to form oxaloacetate. This latter ...

Civstallization is an established method used in the initial recovery of organic acids and amino acids, and more widely used for final purification of a diverse range of compounds.. [n citric acid production, the filtered broth is treated with Ca(OH)2 so that the relatively insoluble calcium citrate crystals will be precipitated from solution. Checks are made to ensure that the Ca(OH)2 has a low magnesium content, since magnesium citrate is more soluble and would remain in solution. The calcium citrate is filtered off and treated with sulphuric acid to precipitate the calcium as the insoluble sulphate and release the citric acid. After clarification with active carbon, the aqueous citric acid is evaporated to the point of crystallization (Lockwood and Irwin, 1964; Sodeck et al., 1981; Atkinson and Mavituna, 1991). Crystallization is also used in the recovery of amino acids; Samejima (1972) has reviewed methods for glutamic acid, lysine and other amino acids. The recovery of cephalosporin C as ...
Normal prostate tissue contains high levels of citrate. In the presence of prostate cancer, the citrate level is diminished. In this paper we show that it is possible to use europium-oxytetracycline complex as a citrate fluorescent probe and consequently as a prostate cancer probe. We analyzed normal nude male mice urine and urine from nude male mice in which prostate cancer was induced by intraprostatic inoculation of DU145 cells. The urine samples were collected from the animals at the 7th, 14th, 21st, and 35th days after the surgery procedures. The intensity of europium emission at 615 nm in europium-oxytetracycline complex in the presence of citrate increases linearly. The citrate concentrations were determined from a calculated calibration curve. A concentration decrease in malignant prostate urine from the normal (PBS group) urine value from ∼8.0 mM to ∼2.4 mM (tumor group at 35th day) was found. The obtained results indicated that europium-oxytetracycline provides a significant ...

Citric acid is a weak organic acid. It is a natural preservative conservative and is also used to add an acidic or sour, taste to foods and soft drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of virtually all living things.. It is colorless or white crystalline powder and mainly used as an acidulant, flavoring and preservative preservative in foods and beverages. It is also used as an antioxidant, plasticizer and detergent, builder.. Mainly used in the food, beverage trade as the sour flavor agent, flavoring agent, antiseptic as well as an antistaling agent. ...

Then, the subject will undergo a sodium citrate nasal douche at a specific concentration or will douche with sterile water. There will be three concentrations used (3%, 6% and 9%) and a control solution (sterile water). Patients will be randomly allocated to one of the four groups using a coded bottle system. Both patient and tester will be blinded to the solution used as these will be made in the pharmacy and coded for anonymity - the code will be broken at the end of the trial. Subjects will then be retested with the bottles and threshold levels will be observed for the four odours at 15 minute intervals over 2 hours. The purpose of the repeated tests is to determine the length of the effect (if present) of the citrate on the olfactory ability of the patients (NB: sodium citrate is a licensed product for use in body cavities (e.g. stomach, bladder) and can be found in the British National Formulary - the concentrations proposed do not exceed those used elsewhere). ...
