Chronic neuropathic pain is a major morbidity of neural injury, yet its mechanisms are incompletely understood. Hypersensitivity to previously non-noxious stimuli (allodynia) is a common symptom. Here, we demonstrate that the onset of cold hypersensitivity precedes tactile allodynia in a model of partial nerve injury, and this temporal divergence was associated with major differences in global ...

Two independent experiments were conducted with broilers to determine the effect of threonine and vitamin A on immune system. In first experiment, dietary treatments contained 0.8%, 0.87%, 0.94 % and 1.01 % total threonine. In second experiment, diets were as follows: basal diet without vitamin A; basal diet plus 1500 IU/Kg vitamin A; basal diet plus 6250 IU/Kg vitamin A; basal diet plus 11000 ...
