A Parkinson's disease patient with deep brain stimulation (DBS) implantation experienced an acute subdural haematoma (SDH) after a fall. The DBS electrodes and brain parenchyma were shifted. Fortunately, the patient recovered after craniectomy and removal of SDH, and the DBS was re-activated with the same parameters. Patients with DBS implants who suffer a(More)
This article considers the problem of scheduling a given set of independent jobs on unrelated parallel machines to minimize the total weighted tardiness. The problem is known to be NP-hard in the strong sense. Efficient lower and upper bounds are developed. The lower bound is based on the solution of an assignment problem, while the upper bound is obtained(More)
The aim of this study was to evaluate peripheral nerve regeneration across a 15-mm gap in the sciatic nerve of the rat, using a silicone rubber nerve guide filled with different concentrations of astragaloside (0, 50, 100, and 200 microM). Collagen was also filled in the chambers to prevent the astragaloside from leakage. At the end of 8 weeks, animals from(More)
This paper addresses the open shop scheduling problem to minimize the total completion time, provided that one of the machines has to process the jobs in a given sequence. The problem is NP-hard in the strong sense even for the two-machine case. A lower bound is derived based on the optimal solution of a relaxed problem in which the operations on every(More)
An approach for generating dependent random variates with specdled margmrd distributions and measure of correlation is developed based upon an analogy between correlation and force. We first examine the mathematical transformation implied by thts analogy and attempt to construct a general algorithm for generating variates that have the desired properties.(More)
Metastasis tumor-associated protein 2 (MTA2) is a member of the MTA family that is closely associated with tumor progression and metastasis. However, the role of MTA2 in glioma cells remains unclear. The expression of MTA2 was measured using immunohistochemistry and western blotting in the human brain tumor tissue array and human glioma cell lines. The(More)
BACKGROUND High-grade primary glioma have poor prognosis and predictive biomarkers is very important. Midkine (MDK), a heparin-binding growth factor, is important in regulating carcinogenesis, cell proliferation, mitogenesis, and angiogenesis. This study aimed to identify over-expression of MDK in gliomas and correlate this with clinical outcomes. The(More)
