The emission potential of different land use patterns for the occurrence of coliphages in surface water.

Different land use patterns were investigated for their potential as non-point sources of coliphage emissions into surface waters. Water samples were taken regularly at five locations in the upper reaches of the river Swist, Germany. Samples of surface and subsurface run-off were taken within the same catchment area after rainfall events using a newly developed device that made it possible to collect current concentrations of the effluent compounds.

Are advanced glycation end products cardiovascular risk factors in patients with CRF?

Background: Chronic renal failure (CRF) is characterized by enhanced formation and accumulation of advanced glycation end products (AGEs), which are involved in the pathogenesis of vascular damage. Their role as risk factors for cardiovascular complications is still unknown. This study aims to investigate whether elevated serum levels of the AGEs pentosidine, N(epsilon)-carboxymethyllysine (CML), and the 3-deoxyglucosone-derived imidazolone involve a greater risk for cardiovascular events (CVEs) and left ventricular hypertrophy (LVH).
