Animal disease regionalization and its impact on tropical countries.
This paper reviews progress that has been made around the world in animal disease regionalization. Signatory countries of the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) and other free-trade associations are currently implementing regionalization, one of the cornerstone provisions of the Uruguay Round of the GATT and the World Trade Organization's (WTO) Sanitary and Phytosanitary Agreement. ⋯ The implementation of regionalization by importing countries affects export markets of tropical nations. Veterinary officials of tropical countries must give regionalization due priority such that import and export trade in animals and animal products is not hindered, and the public and animal herd health are protected.

Aging is associated with the loss of brain neurotransmitter function, which apparently is the substrate for an adverse constellation of age-associated symptoms. In particular, cholinergic deficits have been associated with cognitive impairment in aging. ⋯ In addition to correcting cholinergic neurochemistry, it improves spatial learning and memory impairment, and restores the number and the size of the cholinergic neurons in the basal forebrain and striatum. The induced neuronal recovery by GM1 is long-lasting.
