In this work, the different fuels (citric acid, glycine and urea) were used for solution combustion synthesis of CoFe2O4 powders. X-ray diffraction, Raman spectroscopy, electron microscopy and vibrating sample magnetometry techniques were employed for characterization of phase evolution, cation distribution, microstructure and magnetic properties of the as-combusted CoFe2O4 powders. Single phas...

Berries such as strawberries are recognized a significant constituent of healthy human diets owing to their bioactive secondary metabolites. To improve crop sustainability, yield and berry quality, alternative production systems should be proposed organic farming the use biostimulants. Thus, we have compared within complete randomized block design seven biostimulant treatments: 1-control, 2-sea...

in this study, variations of the pasting properties, swelling power and solubility of two rice starches, low amylose (8.7%) and high amylose (26%) at two citric acid concentrations (0 and 0.01 m) was investigated. the results showed that the peak viscosity and breakdown viscosity of rice starch decreased significantly (p 0.05).the swelling power and solubility of both starch pastes with and wit...

Nano-crystalline TiO2 were synthesized by combustion method using metal nitrate solution and urea, glycin and citric acid fuels. Microwave irradiation was used as heating source. X-ray diffraction, scanning electron microscope as well as Fourier transform infrared spectroscopy were performed to characterize the obtained samples. X-ray diffraction patterns revealed that in the case of citric aci...

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...

Soil samples were collected from the different locations in Sathuragiri Hills (Western Ghats, Tamilnadu). The Total Fungal Counts in the soil samples of the different locations were analyzed. The percentage frequencies of occurrence of fungal isolates are identified. The fungal isolates were identified based on the morphological and cultural characteristics they were identified as Cladosporium ...

Epsilon poly-L-lysine (ε-PL) is a homo-biopolymer with approximately 25-30 L-lysine residues. It is a promising natural biopolymer widely used in food and pharmaceutical industry. The present work reports enhanced production of ε-PL with a novel producer Bacillus cereus using amino acids and TCA cycle intermediates in the fermentation medium. Among the various amino acids and TCA cycle intermed...

objective: today, esophageal cancer (ec) has become one of the most common cancer types in china. therefore, new drug and therapeutic strategies are urgently needed to improve postoperative survival rate of patients with ec. as a food additive, several lines of evidence have shown that citric acid can be served as glycolysis suppressor to inhibit growth of some tumor cells. however, little is k...

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...

Citric acid has been shown to act as an agent for increasing the solubility of aluminum oxyhydroxides in aqueous solutions of high (>2.47 mol/mol) hydroxide-to-aluminum ratios. Conversely, citric acid also colloidally stabilizes particles in aqueous suspensions of aluminum-containing particles. Solutions of aluminum chloride, with and without citric acid added, were titrated with NaOH(aq). The ...
