Based on the study of motion vector distribution from several commonly used test image sequences, a new diamond search (DS) algorithm for fast block-matching motion estimation (BMME) is proposed in this paper. Simulation results demonstrate that the proposed DS algorithm greatly outperforms the well-known three-step search (TSS) algorithm. Compared with the(More)
Minocycline mediates neuroprotection in experimental models of neurodegeneration. It inhibits the activity of caspase-1, caspase-3, inducible form of nitric oxide synthetase (iNOS) and p38 mitogen-activated protein kinase (MAPK). Although minocycline does not directly inhibit these enzymes, the effects may result from interference with upstream mechanisms(More)
Minocycline is broadly protective in neurologic disease models featuring cell death and is being evaluated in clinical trials. We previously demonstrated that minocycline-mediated protection against caspase-dependent cell death related to its ability to prevent mitochondrial cytochrome c release. These results do not explain whether or how minocycline(More)
Creatine mediates remarkable neuroprotection in experimental models of amyotrophic lateral sclerosis, Huntington's disease, Parkinson's disease, and traumatic brain injury. Because caspase-mediated pathways are shared functional mechanistic components in these diseases, as well as in ischemia, we evaluated the effect of creatine supplementation on an(More)
HMGB1 is associated with human cancers and is an activator of autophagy which mediates chemotherapy resistance. We here show that the mRNA levels of HMGB1 are high in leukemia cells and it is involved in the progression of childhood chronic myeloid leukemia (CML). HMGB1 decreases the sensitivity of human myeloid leukemia cells K562 to anti-cancer drug(More)
We investigated whether permeability transition-mediated release of mitochondrial cytochrome c is a potential therapeutic target for treating acute spinal cord injury (SCI). Based on previous reports, minocycline, a second-generation tetracycline, exerts neuroprotection partially by inhibiting mitochondrial cytochrome c release and reactive microgliosis. We(More)
Epithelial to mesenchymal transition (EMT) plays an important role in many biological processes. The latest studies revealed that aggressive breast cancer, especially the triple-negative breast cancer (TNBC) subtype was frequently associated with apparent EMT, but the mechanisms are still unclear. NEDD9/HEF1/Cas-L is a member of the Cas protein family and(More)
This study was to characterize the neuroprotective effects of nortriptyline, a tricyclic antidepressant, in mouse models of chronic neurodegeneration [amyotrophic lateral sclerosis (ALS) and Huntington's disease (HD)]. Nortriptyline was originally selected from a library screening of 1040 FDA-approved drugs by using isolated mitochondria. It emerged as a(More)
BACKGROUND AND PURPOSE The identification of a neuroprotective drug for stroke remains elusive. Given that mitochondria play a key role both in maintaining cellular energetic homeostasis and in triggering the activation of cell death pathways, we evaluated the efficacy of newly identified inhibitors of cytochrome c release in hypoxia/ischemia induced cell(More)
Gliomas are extremely aggressive brain tumors with a very poor prognosis. One of the more promising strategies for the treatment of human gliomas is targeted immunotherapy where antigens that are unique to the tumors are exploited to generate vaccines. The approach, however, is complicated by the fact that human gliomas escape immune surveillance by(More)
