September 2013
Digital macro photography and settling tests were carried out to investigate the morphological and settling characteristics of ANAMMOX granules in a high-rate reactor. The ANAMMOX granules could be divided into settling and floating granules. The settling granules with an average diameter of 2.

The results showed that the anammox granules were irregular in shape and uneven on surface, and their structure included granule, subunit, microbial cell cluster and single cell. The gas pockets were often observed in the anammox granules, and they originated from the obstruction of gas tunnel by extracellular polymer substances (EPSs) and the inflation of produced dinitrogen gas.

Article Synopsis
- The study aimed to explore the early stages of multiple organ injuries in rats caused by ischemia and reperfusion of the intestines and liver.
- Researchers used 75 male Wistar rats, dividing them into groups for hepatic ischemia, intestinal ischemia, and combined ischemia, measuring various biochemical markers at specific time points.
- Results indicated a significant decrease in superoxide dismutase (SOD) activity and an increase in markers for organ damage and stress, suggesting that intestinal ischemia may cause more severe early-stage injuries compared to hepatic ischemia.
