BACKGROUND AND OBJECTIVES The effectiveness of acupuncture in relieving acute postoperative pain is still controversial. This patient-evaluator blinded and sham auricular acupuncture (AA)-controlled study tested whether acupuncture is effective in controlling acute postoperative pain after total knee arthroplasty. METHODS Patients were randomly assigned(More)
Neuroinflammation is a hallmark of neurodegenerative disorders in the central nerve system (CNS). Thrombin has been known as one of the factors in pathological processes including migration, blood-brain barrier breakdown, brain edema formation, neuroinflammation, and neuronal death. Thrombin has been shown to be a regulator of matrix metalloproteinase(More)
The intercellular adhesion molecule-1 (ICAM-1) expression is frequently correlated with the lung inflammation. In lung injury, sphingosine-1-phosphate (S1P, bioactive sphingolipid metabolite), participate gene regulation of adhesion molecule in inflammation progression and aggravate tissue damage. To investigate the transduction mechanisms of the S1P in(More)
Matrix metalloproteinase-9 (MMP-9) plays a crucial role in pathological processes of brain inflammation, injury, and neurodegeneration. Thrombin has been known as a regulator of MMP-9 expression and cells migration. However, the mechanisms underlying thrombin-induced MMP-9 expression in rat brain astrocytes (RBA-1 cells) remain unclear. Here, we(More)
An elevated level of glucose has been found in the blood of hyperglycemia and diabetes patients associated with several central nervous system (CNS) complications. These disorders may be due to the up-regulation of many neurotoxic mediators by host cells triggered by high glucose (HG). Moreover, increased plasma levels of matrix metalloproteinases (MMPs),(More)
Upregulation of intercellular adhesion molecule-1 (ICAM-1) is frequently implicated in lung inflammation. Lipopolysaccharide (LPS) has been shown to play a key role in inflammation via adhesion molecule induction and then causes lung injury. However, the mechanisms underlying LPS-induced ICAM-1 expression in human pulmonary alveolar epithelial cells(More)
Thrombin has been known to activate inflammatory genes including matrix metalloproteinases (MMPs). The elevated expression of MMP-9 has been observed in patients with neuroinflammatory diseases and may contribute to the pathology of brain diseases. However, the mechanisms underlying thrombin-induced MMP-9 expression in SK-N-SH cells remain unknown. The(More)
Endothelin-1 (ET-1), a proinflammatory mediator, is elevated in the regions of several brain inflammatory disorders, implying that ET-1 may contribute to inflammatory responses. The deleterious effects of ET-1 on brain endothelial cells may aggravate brain inflammation mediated through the upregulation of cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2)(More)
It is not energy efficient to run a CPU at full speed all the time for all kinds of tasks in mobile devices. This paper proposes two energy efficient intra-task dynamic voltage scaling (DVS) algorithms for CPUs. There are three main contributions in this paper. Firstly, unlike the tedious derivation in PACE [2], we have derived the same optimal speed(More)
The inflammation-dependent adhesion molecule expressions are characterized in cardiovascular diseases and myocardial tissue infiltrations. Several pro-inflammatory cytokines are elevated in the acute myocardial injury and infarction. Tumor necrosis factor-α (TNF-α), a pro-inflammatory cytokine, is raised in the injury tissues and inflammatory regions and(More)
