PURPOSE The comparison of nutrition of children with high level of physical activity in dependence on antioxidative efficiency expressed in Ferric Reducing Ability of Plasma--FRAP adapted for saliva. MATERIAL AND METHODS The group consisted of 74 pupils (43 boys and 31 girls) from swimming classes of Sport Championship School in Kraków. FRAP was measured in saliva with the use of colorimetric...

An infusion of the wolfberry (Lycium barbarum L.) is a traditional Asian herbal tea. This is the most commonly consumed form of dried wolfberry worldwide, yet little scientific information on wolfberry infusions is available. We investigated the effects of making infusions with hot water on the color, the content of bioactive compounds (polysaccharides, polyphenols, flavonoids and carotenoids) ...

A rapid and highly sensitive bicinchoninic acid (BCA) reagent-based protein quantitation tool was developed using competitive resonance Raman (RR) and surface-enhanced resonance Raman scattering (SERRS) methods. A chelation reaction between BCA and Cu(+), which is reduced by protein in an alkaline environment, is exploited to create a BCA-Cu(+) complex that has strong RR and SERRS activities. U...

OBJECTIVE Determination and comparison of the effect of infusion time on the antioxidant activity and total polyphenol contents of bagged and loosely packed black teas. MATERIALS AND METHODS For twenty loosely packed and eleven bagged tea samples, the antioxidant activity and total polyphenol content were analyzed using FRAP and Folin-Ciocalteau methods, respectively. The ANOVA with Tukey pos...

Comparative analysis of antioxidant capacity was performed using FRAP and DPPH methods on extracts containing carotenoids acquired from fruits of Sea buckthorn. The examination included nine varieties of Sea buckthorn growing in the comparative cultivation. Conducted analysis allowed to compare the antioxidant capacity with carotenoids content measured with spectrophotometric and HPLC methods. ...

This paper focuses on the problem of bringing a business process document to a consistent state after exceptional occurrences. Although many traditional recovery methods can support exception handling, they are mainly concerned with process backtracking, forward stepping, and compensation. However, prior to the use of recovery algorithms, it is essential to find a rollback activity for organiza...

To determine the role of intramitochondrial protein synthesis (PS) and degradation (PD) in contractile activity-induced mitochondrial biogenesis, we evaluated rates of [(35)S]methionine incorporation into protein in isolated rat muscle subsarcolemmal (SS) and intermyofibrillar (IMF) mitochondria. Rates of PS ranged from 47 to 125% greater (P < 0.05) in IMF compared with SS mitochondria. Intense...

a new chemical compound is developed at petroleum university of technology to enhance therecovery of the free imbibition process and simultaneously hinder asphaltene precipitation. thecompound is tested on heavy oil samples from marun oil field, bangestan reservoir. the effects ofthe chemical compound on viscosity, hydrocarbon composition, and average molecular weight ofthe heavy oil are invest...

Modern economies experience recurrent fluctuations in business activity. As output and employment fall in recessions and busts and rise in recoveries and booms, other variables of economic significance also go through lows and highs. One such variable is real wages. Generally speaking, real wages are he cyclical behavior of real wages — wages adjusted for inflation — has changed over time. Befo...

Writing a college self-study can have two personal outcomes for the author. One is to cheer that the damn thing is over and cleanse the mind by turning to radically different matters. But the other is to get hooked on making sense of the place, where it’s come from, where it’s going, and why. For some pieces of the self-study, I found that the former outcome applied in spades. But for others, p...
