One of the main features quality Dnieper water is content natural organic substances which determine oxidizability and color indexes. A special problem that are poorly removed by treatment plants. significant in operation plants unpredictability annual changes water, complicates logistics management, for example, supply reagents. Many years experience related to station Kyiv (DnWS) have led hyp...

Constructing step-scheme (S-scheme) heterojunctions has been confirmed as a promising strategy for enhancing the photocatalytic activity of composite materials. In this work, series sulfur-doped g-C3N4 (SCN)/TiO2 S-scheme photocatalysts were synthesized using electrospinning and calcination methods. The as-prepared SCN/TiO2 composites showed superior performance than pure TiO2 SCN in degradatio...

In human populations, there is an association between coronary artery disease and a polymorphism in the apolipoprotein B (apo B) gene detected with the enzyme EcoKl. This polymorphism gives rise to two apo B alleles, one (E) encoding glutamic acid and the other (E~) encoding lysine at position 4,154 in apo B-100, the protein of low density lipoprotein (LDL). We have tested the hypothesis that t...

A randomized, double-masked, crossover clinical trial was carried out to evaluate whether lovastatin therapy (60 mg daily) affects the initiation of oxidation of low density lipoprotein (LDL) in cardiac patients on a-tocopherol supplementation therapy (450 IU daily). Twenty-eight men with verified coronary heart disease and hypercholesterolemia received a-tocopherol with lovastatin or with dumm...

Oxidative stress plays an important role in the pathogenesis of neurodegenerative diseases, such as Parkinson's disease (PD). There are several methods to measure oxidative stress, being lipid peroxidation (LPO) one of the most frequently used. Endogenous plasma LPO was determined by a spectrofluorimetric method in fifty two patients with sporadic PD and in forty controls. To know the maximum c...

LDL oxidation may promote atherosclerosis. We found that polyenyphosphatidylcholine (PPC), a mixture of polyunsaturated phospholipids extracted from soybeans, has antioxidant effects in in vivo models of oxidative stress. To assess whether components of PPC affect the in vitro oxidizability of LDL, plasma from 15 healthy volunteers was incubated with 10 microM of either dilinoleoyl-, palmitoyl-...
