Fat-soluble vitamin regulation is of particular significance in cystic fibrosis. A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. In the present study, we had developed a simple method to estimate the fat soluble vitamin by Spectrophotometer. The vitamin A, D, E and K were estimated by spectrophotometer at 325 nm, 264 nm, 525 nm and 635 nm respectively. Af...

The stability of the natural sweetener stevioside during different processing and storage conditions as well as the effects of its interaction with water-soluble vitamins, food relevant organic acids and other common low calorie sweeteners and its application in coffee and tea beverages were evaluated. Incubation of the solid sweetener stevioside at elevated temperatures for 1 h showed good sta...

PURPOSE Some scientific studies show decreased bone mineral density and increased fracture frequency in adult patients with cystic fibrosis (CF). The mechanism for early bone loss in CF patients are multifactorial: chronic pulmonary inflammation, malnutrition, reduced physical activity, delayed pubertal maturation. The aim of this study was to assess bone metabolism markers with special attenti...

BACKGROUND There is evidence for a role of oxidant stress and inflammation in atrial fibrillation (AF). Statins have both antioxidant and antiinflammatory properties. We compared the effects of simvastatin with those of antioxidant vitamins on AF promotion by atrial tachycardia in dogs. METHODS AND RESULTS We studied dogs subjected to atrial tachypacing (ATP) at 400 bpm in the absence and pre...

Although there are numerous methods for quantitative determination of antioxidative vitamins: C, E, and A, there are no methods favourable for the broadly understood analytic practice – they have various faults and limitations or require expensive apparatus. Therefore, we have elaborated modifications of valuable spectrophotometric methods for determination each of those vitamins, which origina...
