BACKGROUND: In Parkinson's disease there is progressive loss of dopamine containing neurons in the substantia nigra pars compacta. The neuronal damage is not limited to the substantia nigra but progresses to other regions of brain, leading to loss of motor control as well as cognitive abnormalities. The purpose of this study was to examine causes of progressive damage in the caudate nucleus, which plays a major role in motor coordination and cognition, in experimental Parkinson's disease.

RESULTS: Using chronic 1-methyl-4phenyl-1,2,3,6-tetrahydropyridine treatment of rhesus monkeys to model Parkinson's disease, we found a upregulation of Cathepsin D, a lysosomal aspartic protease, in …

The prevalence of bovine viral diarrhea virus (BVDV) in 406 cattle was evaluated of both sexes and older than 6 months. Animals belonged to 114 small farmers from three rural communities of the province of Espinar, Cusco, Peru. Blood samples were collected according to three age groups Ɩ-12, 13-23, >24 months old). Serum samples were tested for antibodies against BVDV using the viral neutralization test. The 56.2 ± 4.8% 鴤/406) of samples had antibodies against BVDV. Persistently infected animals were not detected. Antibodies were present in the three age groups, but the highest prevalence ࿡.4%) was detected in animals older …
