Expression of Matrix Metalloproteinases in the Circulating Immune Cells in Children with Infection-Correlation with Clinical Factors.

gastritis is strongly associated with the upregulation of the expression of several matrix metalloproteinases (MMPs) in the gastric mucosa. However, the role of MMP-2 and MMP-9, and their inhibitors (tissue inhibitors of metalloproteinases -TIMPs) produced by immune cells in infected children have not been clearly defined. Moreover, the effects of eradication therapy on MMPs and TIMPs production has not been evaluated.

Histopathology of liver and kidneys of wild living Mallards Anas platyrhynchos and Coots Fulica atra with considerable concentrations of lead and cadmium.

Concentrations of cadmium and lead were measured in liver and kidneys of Mallard (n=60) and Coot (n=50). Free living birds were collected by hunters in years 2006-2008 in the area of fishponds near Zator in southern Poland. Age group was determined according to the appearance of the plumage (Mallards) and iris color (Coot).
