According to current views on the intermediary metabolism of carbohydrate, both thiamine and citric acid are significant factors in the oxidation of this foodstuff, Thiamine in its phosphorylated form has been shown (Banga, Ochoa, and Peters, 1939) to be required for the oxidative removal of the pyruvic acid produced in the course of carbohydrate breakdown. Likewise, according to Krebs and John...

A solution based economically low cost, eco-friendly, and energetically advantageous alternative route for the fabrication of ultrafine LiFe0.95Ti0.05PO4 (LFTP) LiFePO4 (LFP) polycrystalline materials by semi-wet combustion sol–gel synthesis is presented in this chapter. The energy dispersive X-ray (EDX) spectra LFP LFTP material were observed with high-resolution transmission electron microsco...

Citric acid is recognized and utilized as a dietary supplement for its ability to eliminate fatigue. However, the molecular and cellular mechanism underlying this effect has not been elucidated. This study investigated the effect of intragastric citric acid administration on the energy metabolism and gene expression in the skeletal muscles of mice that had been fasted without exercise, using bi...

Aconitase and NADand NADP-linked isocitric dehydrogenases were examined in two strains of Aspergillus niger. The mutant strain 72-44 produced higher yields of citric acid on the culture medium used than did the parent strain 7 2 4 . After growth for 22 hr on a medium in which citric acid did not accumulate, the amounts of each enzyme in the parent strain were approximately the same as those in ...

BACKGROUND Cough is an important symptom of patients with chronic obstructive pulmonary disease (COPD). The cough threshold to citric acid and capsaicin in patients with COPD and in normal volunteers was measured, as well as bronchial hyperresponsiveness to methacholine. METHODS Nineteen patients with COPD and 22 controls were recruited. Subjects underwent a methacholine bronchoprovocation te...

AIM To evaluate and compare ex vivo the decalcifying effect of 15% EDTA, 15% citric acid, 5% phosphoric acid and 2.5% sodium hypochlorite on root canal dentine. METHODOLOGY Two 2-mm-thick slices were cut from the coronal third of the root of 10 human incisors. Each slice was sectioned into two equal parts. Specimens were assigned to one of four groups (n = 10) for immersion in 20 mL of either...

abstract mefenamic acid is a nonsteroidal anti-inflammatory drug (nsaid) that has analgesic,anti-infammatory and antipyretic actions. it is used to relieve mild to moderate pains. solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . poly allyl glycidyl ether/iminodiacetic acid-co-n, n-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

This paper reports a study on nanocrystalline ceria powder prepared by high energy ball-milling and combustion synthesis methods. The combustion synthesis was carried out using ceric ammonium nitrate as oxidizer and citric acid, glycine or citric acid plus glycine as fuel. The minimum crystallite size of ceria powder is obtained by combustion synthesis of ceric ammonium nitrate and citric acid....

Chicken breast dipped with citric acid (CA) was treated by sous vide processing and stored in a refrigerated state for 0, 3, 6, 9, and 14 d. A non-dipped control group (CON) and three groups dipped in different concentrations of citric acid concentration were analyzed (0.5%, 0.5CIT; 2.0%, 2CIT and 5.0%, 5CIT; w/v). Cooking yield and moisture content increased due to the citric acid. While the r...

An experiment was conducted to study the effects of xylanase and citric acid on the performance, nutrient retention, jejunal viscosity, and size and pH of the gastrointestinal tract of broilers fed a low-P wheat-based diet. The experiment was conducted as a 2 × 3 factorial arrangement with 2 levels of xylanase (0 and 200 mg/kg) and 3 levels of citric acid (0, 20, and 40 g/kg). Each of the 6 die...
