Urea is authorised in the European Union (EU) as feed additive for ruminants. Because of its high molecular nitrogen content, it a substance potential protein adulteration non-ruminant feed. The EU defines spectro-colorimetric method an official control determination urea feed, whereas Association Official Analytical Chemists (AOAC) United States recommends enzymatic method. Discrepancies betwe...

Polycyclic aromatic hydrocarbons (PAHs) are compounds widespread in the environment, many of them showing carcinogenic effects. These compounds can reach the food chain by different ways and, therefore, the analysis of PAHs in food is a matter of concern. The purpose of this paper is to determine the polycyclic aromatic hydrocarbons from fruit juices using high performance liquid chromatography...

Generally fatty liver disease (FLD) is attributed either to alcohol, diabetes mellitus, or obesity. To evaluate this commonly held clinical belief, a case-control study of FLD in Western Pennsylvania was conducted with 19 cases being identified over a two year period. Cases of FLD were significantly heavier and were significantly more likely than controls to have exposures to either agents with...

Iron limitation affects one-third of the cultivable land on Earth and represents a major concern for agriculture. It causes decline of many photosynthetic components, including the Fe-S protein ferredoxin (Fd), involved in essential oxidoreductive pathways of chloroplasts. In cyanobacteria and some algae, Fd down-regulation under Fe deficit is compensated by induction of an isofunctional electr...

Chloroplast ferredoxin (Fd) plays a pivotal role in plant cell metabolism by delivering reducing equivalents to various essential oxidoreductive pathways. Fd levels decrease under adverse environmental conditions in many microorganisms, including cyanobacteria, which share a common ancestor with chloroplasts. Conversely, stress situations induce the synthesis of flavodoxin (Fld), an electron ca...

BACKGROUND The purpose of this survey was to confirm the prevalence and adverse profiles of fatty liver disease among different ethnic public servants in Urumqi of Xinjiang. METHODS The cross-sectional study were implemented among serving and retired public servants who participated in the annual physical check-up including abdominal ultrasonography from April 2012 to April 2013 at the health...

As part of the certification campaign of three candidate reference materials for the determination of aflatoxin M1 (AfM1) in whole milk powders, homogeneity, short- and long-term stability tests of naturally contaminated milk powders have been performed. The homogeneity of two AfM1-contaminated milk powders was studied by taking samples at regular intervals of the filling sequences and analysin...
