Retrospective analysis of the relationship between elevated plasma levels of TXNIP and carotid intima-media thickness in subjects with impaired glucose tolerance and early Type 2 diabetes mellitus.

Aims: Accelerated atherosclerosis is the major cause of mortality in diabetic patients and increased oxidative stress probably plays an important role in its development. The aim of our study was to evaluate the relationship between thioredoxin-interacting protein (TXNIP) as an oxidative stress parameter and carotid artery intima-media thickness (CIMT) as an indicator of atherosclerosis in patients with early-state diabetes and impaired glucose tolerance.

Methods: The study was a retrospective analysis of 90 patients with impaired glucose regulation (IGR), 80 patients with early Type 2 diabetes mellitus (T2DM), and 80 subjects with normal glucose tolerance (NGT) as the control group.

Remotely sensed assessment of water quality levels in the Pearl River Estuary, China.

In this paper, a method of assessing water quality from satellite data is introduced. The composite pollution index (CPI) was calculated from measured chemical oxygen demand (COD) and nutrient concentration. The relationships between CPI and 240 band combinations of SeaWiFS water-leaving radiance were analyzed and the optimal band combination for estimating CPI was chosen from the 240 band combinations.
