Intravenous iron, used for the treatment of anemia in chronic renal failure andother diseases, represents a possible source of free iron in tissue cells, particularly in the liver. In this study we examined the effect of different sources of intravenous iron (IVI) on the labile iron pool (LIP) which represents the nonferritin-bound, redox-active iron that is implicated in oxidative stress and cell injury. Furthermore, we examined the role of the LIP for the synthesis of ferritin.

The enzymatic properties of chitinase A fromVibrio carchariaehave been studied in detail by using combined HPLC and electrospray MS. This approach allowed the separation ofaandbanomers and the simultaneous monitoring of chitooligosaccharide products down to picomole levels. Chi-tinase A primarily generated b-anomeric products, indicating that it cata-lyzed hydrolysis through a retaining mechanism.

Pesticides are used to protect crops from insects, weeds and diseases both in dryland and irrigated crop production in Viet Nam. However, reliance on pesticides in crop production system has the potential to cause environmental problems due to contamination of waterways and of produce, adversely affecting the Vietnamese environment and human health.
