Omani citrus fruits were analyzed for their Vitamin C (ascorbic and AA) content by a titration method involving N-bromosuccinimide (NBS) as an oxidizing agent and by high performance liquid chromatography. Vitamin C content was also determined after storage at different temperatures. Vitamin C contents of the fruits we …
… PRK surgery. The patients were randomly divided into two groups as follows: case group who received oral ascorbic acid 250 mg once daily for 7 days and control group that took placebo 3 days before and 4 days after the surgical operation. The patients underwent a surgical operation on day 0. Then, the following factor …
… and sensory assessments were done. In chemical analysis, it was found that variances in the scores of pH, ascorbic acid, titratable acidity, total sugar and reducing sugar were significant (p< 0.05). Squash formulations showed an increasing trend in titratable acidity (0.43 % -0.64 %), pH (3.37 - 4.08), total sugar (11 …
… ts were evident for a promising efficiency of OGO-GCE on the simultaneous determination of dopamine (DA), ascorbic acid (AA) and uric acid (UA). In addition, the selectivity of the proposed sensor for DA quantification in the presence of high concentrations of AA and UA was achieved successfully with a detection limit …
… 22 ppb). It was also applied for selective determination of NOR in the presence of high concentrations of ascorbic acid (AA) and uric acid (UA). The interference study highlighted the great stability of the proposed sensor by generating a similar sensitivity as in the pure NOR solution. The analytical performance of th …
… or turned chocolate brown. After the resolution of COVID-19 in 10 days, the patient was treated with oral ascorbic acid and successful atrial septal defect repair. It is important to suspect dyshemoglobin disorder in a patient who presents with hypoxia/hypoxemia.
