An irreversible inhibitor of complex II in the mitochondria, 3-nitropropionic acid (3-NP), induces bilateral striatal lesions with many neuropathological features of Huntington’s disease (HD) in rats. It is widely used as a model of HD. Chronic systemic treatment of 3-NP for 4 days in rats (10, 15 and 20 mg/kg) caused a significant dose-dependent reduction in succinate dehydrogenase activity, w...
In this paper we show that the Inverse problems of HAMILTONIAN CYCLE and 3D-MATCHING are coNP complete. This completes the study of inverse problems of the six natural NP-complete problems from [GJ79] and answers an open question from [Ch03]. We classify the inverse complexity of the natural verifier for HAMILTONIAN CYCLE and 3D-MATCHING by showing coNP-completeness of the corresponding inverse...
Motivated by a conjecture of Liang [Y.-C. Liang. Anti-magic labeling of graphs. PhD thesis, National Sun Yat-sen University, 2013.], we introduce a restricted path packing problem in bipartite graphs that we call a V-free 2-matching. We verify the conjecture through a weakening of the hypergraph matching problem. We close the paper by showing that it is NP-complete to decide whether one of the ...
The striatum is particularly sensitive to the irreversible inhibitor of succinate dehydrogenase 3-nitropropionic acid (3-NP). In the present study, we examined early changes in behavior and dopamine and glutamate synaptic physiology created by a single systemic injection of 3-NP in Fischer 344 rats. Hindlimb dystonia was seen 2 h after 3-NP injections, and rats performed poorly on balance beam ...
