The aim of this study was to evaluate the influence of using Citric Acid on false negative rates induced by PPIs during 14C–UBT in dyspeptic patients with H. pylori infection. In a crossover randomized controlled clinical trial, one hundred dyspeptic patients (46 females and 54 males) with determined H. pylori infection who referred to gastrointestinal Outpatient Clinic of Razi Hospital-Rasht, ...

Infection is one of the most important obstacles in the wound-healing process. Conventional methods used for the treatment of wound infections have their own limitations and hence, are difficult to control. If infection is not addressed well in time, it will further increase morbidity and cost of treatment. An attempt was made to develop a simple and effective treatment modality by using citric...

The “citric acid cycle” hypothesis of carbohydrate oxidation has stimulated an interest in the general relationship of citric acid to carbohydrate metabolism. Krebs and Johnson (1937, a) and Krebs (1937) have presented evidence which they believe demonstrates that a catalytic system composed of certain dicarboxylic acids and citric acid “outlines the principal pathway of the oxidative breakdown...

Gastroesophageal acid reflux into the airways can trigger asthma attacks. Indeed, citric acid inhalation causes bronchoconstriction in guinea pigs, but the mechanism of this effect has not been fully clarified. We investigated the role of tachykinins, bradykinin, and nitric oxide (NO) on the citric acid- induced bronchoconstriction in anesthetized and artificially ventilated guinea pigs. Citric...

Citric acid is a regular ingredient in many vase solution formulations but pre-harvest use of citric acid is a novel method in vase life extension of cut flowers, which is reported on tuberose earlier. In order to verify previous result, and check for possible substitution of citric acid by malic acid, the current research was designed. Citric acid (0, 0.075, 0.15% w/v) and malic acid (0, 0.075...

Among the various fungal strains screened for citric acid production, Aspergillus niger is known to produce considerable amounts of citric acid and other organic acids when cultivated in carbohydrate-rich medium of fermentation. A number of indigenous raw materials such as cane molasses and pumpkin have been carried out in present study for citric acid production by using gamma ray induced muta...

The aim of this study was to evaluate the influence of using Citric Acid on false negative rates induced by PPIs during (14)C-UBT in dyspeptic patients with H. pylori infection. In a crossover randomized controlled clinical trial, one hundred dyspeptic patients (46 females and 54 males) with determined H. pylori infection who referred to gastrointestinal Outpatient Clinic of Razi Hospital-Rasht...

Citric acid is mainly produced by solid state fermentation by the filamentous fungus Aspergillus niger. Production of citric acid depends strongly on an appropriate strain and on operational conditions such as aeration, type and concentration of carbon source, nitrogen and phosphate limitation, pH, temperature, concentration of trace elements and morphology of the producer organism. The yield o...

There is a great worldwide demand for citric acid consumption due to its low toxicity when compared with other acidulants used mainly in the pharmaceutical and food industries. Other applications of citric acid can be found in detergents and cleaning products, cosmetics and toiletries, and other. Global production has now reached 1.4 million tonnes and there is annual growth of 3.5–4.0 % in dem...

Two experiments were conducted. The first tested the hypothesis that KC1 or citric acid or both increase plasma clearance of Mg by lowering tubular reabsorption of Mg in the kidney. Plasma and urinary responses in mature ewes to intraruminal KC1, citric acid, KC1 + citric acid and a water control were evaluated in a 4 • 4 Latin square design. An IV injection of Mg (300 mg) at time 0 was used to...
