Mitochondrial activity determines aging rate and the onset of chronic diseases. The mitochondrial permeability transition pore (mPTP) is a pathological in inner membrane thought to be composed F-ATP synthase (complex V). OSCP, subunit synthase, helps protect against mPTP formation. How destabilization OSCP may contribute aging, however, unclear. We have found that loss nematode Caenorhabditis e...

The mitochondrial permeability transition pore (mPTP) is a non-selective, large-conductance channel that is closed under physiological conditions. Opening of the mPTP, leading to abolition of mitochondrial functions, is a major mechanism of myocyte necrosis by ischaemia/reperfusion, and direct inhibition of mPTP opening by use of pharmacological or genetic manipulations limits infarct size in v...

Single-loop methods based on the Karush–Kuhn–Tucker conditions are considered to be efficient reliability design optimization (RBDO) methods. The probabilistic performance functions converted deterministic for reducing computational burden of analysis. However, most probable target point (MPTP) estimated using steepest descent search directions diverges or oscillates highly nonlinear functions....

Purpose: To study the potential neuroprotective effects of tanshinone IIA, a diterpene quinone, in an experimental model 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced Parkinson disease (PD).
 Methods: Mice (C57BL/6) were administered freshly-prepared MPTP at dose 20 mg/kg body weight intraperitoneally, 4 times 2-h intervals, to induce PD. Doses 12.5, 25 and 50 IIA mice as ...

The proton-activated G protein-coupled receptor (GPCR) 4 (GPR4) is constitutively active at physiological pH, and GPR4 knockout protected dopaminergic neurons from caspase-dependent mitochondria-associated apoptosis. This study explored the role of in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated mouse model Parkinson’s disease (PD). In mice, subchronic MPTP administration cause...

Objective(s): It is known that treadmill exercise has   beneficial effects on the nervous system. The brain-derived neurotrophic factor (BDNF) plays a role in such effects. This study aimed at investigating effects of intermittent treadmill exercise-induced behavioral, histology, and immunohistochemistry (H&E;, TH) measurement of brain interleukin-10 (IL-10) in a mice m...

Norepinephrine (NE) depletion caused by damage to locus ceruleus neurons was shown to worsen experimental Parkinsonism induced by the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in monkeys and in rodents. However, it is not clear whether the lesion to the NE system enhances neurotoxicity in the nigrostriatal dopaminergic (DA) pathway and/or impairs the recovery of DA neurons ...
