The aim of this study was to provide an overview the approaches and methods used assess dynamics soil organic matter (SOM). This included identifying relevant processes that describe estimate SOM decomposition, lability, humification for purpose sustainable management. Various existing techniques models qualitative quantitative assessment were evaluated gain a better understanding advances in t...

Oxidation has been proposed to be an important factor in the pathogenesis of Alzheimer’s disease (AD) and amyloid is considered to induce oxidation. In biological fluids, including cerebrospinal fluid (CSF), amyloid is found complexed to lipoproteins. On the basis of these observations, we investigated the potential role of lipoprotein oxidation in the pathology of AD. Lipoprotein oxidizability...

The membrane of vesicular stomatitis virus could be readily enriched with exogenous cholesterol by exposing virion suspensions to serum lipoproteins forming complexes with cholesterol or to a carrier of polyvinylpyrrolidone/bovine serum albumin mixed with cholesterol. These procedures increased the cholesterol content of the virion membrane f rom -35 to -60% of the total lipid. Endogenous chole...

Sweet potato (Ipomoea batatas L.) leaves are consumed as vegetables around the world, especially in Southeast Asia. The aim of this study was to investigate the inhibitory effect of sweet potato leaves on low-density lipoprotein oxidation in vitro and in human subjects. We compared the antioxidant activity of 8 kinds of sweet potato leaves. Every sweet potato leaf had high radical scavenging ac...

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 EcoRI. 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 ...

AIMS Vitamin C (ascorbic acid) is a powerful antioxidant but there is limited information on its ability to prevent LDL oxidation and its interaction with other natural antioxidants in vivo. We assessed the effect of 4 weeks pharmacological supplementation with vitamin C 1 g day(-1) on copper induced LDL oxidation and lipid peroxidation. METHODS Blood samples were obtained at baseline and at ...

There are some evidences that the increased oxidative stress and thus increased oxidizability of lipoproteins and DNA can contribute to the development of certain human diseases, such as cardiovascular disease. To confirm the association of DNA damage with cardiovascular disease, we investigated susceptibility of DNA to oxidation in lymphocytes and oxidative stress related parameters in blood o...

Water filter pitchers s are the simplest and most affordable devices for local purification of drinking water from centralized decentralized sources. The main element such is a cartridge containing mixture sorption materials that able to absorb certain impurities water. However, as previous studies demonstrated, quality water, purified with pitcher cartridges currently available on market, does...
