Abstract
We found the alterations of Paneth cells including abnormal Paneth cell granules and expression of lysozyme and defensin 5 in response to lymphocyte depletion by alemtuzumab. Lymphocyte depletion resulted in decreased expression of TNF-alpha, IFN-gamma, IL-10 and TGF-beta in the intestine. The diver...

Abstract
The inhibitory effect of free ammonia (NH(3) or FA) and free nitrous acid (HNO(2) or FNA) on the ammonia oxidizing bacteria (AOB) and the dependence of the AOB activity on the concentration of total inorganic carbon (TIC) are well-established. In contrast, less is know about the effect of high FA an...
