Results: We show that galanin, a neuropeptide expressed in the small intestine, decreases duodenal contraction by stimulating
nitric oxide release from enteric neurons.
This is associated with modification of
hypothalamic nitric oxide release that favors glucose uptake in metabolic tissues such as skeletal muscle, liver, and adipose tissue.
But, since tryptophan is a very strong promoter of bacterial growth, and bacterial infections trigger interferon gamma and
nitric oxide release which can induce ulcerative dermatitis and compulsive behavior in this breed, the possibility can't be ruled out.
In a paper published June 5 in Science, the group traces the source of nitrates to
nitric oxides released through fossil fuel burning that parallels the beginning of the Industrial Revolution.
Our findings suggest that selenium restores a normal metabolic profile and ameliorates vascular responses and endothelial dysfunction in diabetes by regulating antioxidant enzyme and
nitric oxide release.
