This paper presents an optimal economic dispatch for power plants by using modified particle swarm optimization (PSO) algorithm. The economic dispatch problem in power systems is to determine the optimal combination of power outputs for all generating units in order that the total fuel cost can be minimized, furthermore, all practical constraints can be(More)
Bone marrow mesenchymal stem cells (BMSCs) are non-hematopoietic multipotent stem cells capable of differentiating into mature cells. Studies in animal models have indicated that hepatocellular carcinoma (HCC) may originate from genetically mutated BMSCs. Moreover, it has been shown that BMSCs are influenced by and can modulate their micro-environment via(More)
Stem cell‑derived hepatocyte precursor cells represent a promising model for clinical transplantation to diseased livers, as well as for establishment of in vitro systems for drug metabolism and toxicology studies. The present study aimed to establish a new method of induction of hepatocyte differentiation using various factors and evaluate the effect of(More)
PURPOSE Recent studies showed that oncolytic adenoviruses not only have capacity for destruction of tumors but also can be used as potential vectors to express therapeutic genes for therapy of cancer. However, better specificity and mode of transgene expression are required to improve the efficacy and safety if this vector is applied for clinical(More)
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most difficult tumors to be treated. Overexpression of human telomerase reverse transcriptase (hTERT) and dysfunction of retinoblastoma (RB) have been implicated in HCC. Oncolytic viruses have been used as targeting therapy for different malignancies. In study, we have engineered oncolytic adenovirus(More)
Although the pathogenetic mechanisms of diabetic nephropathy (DN) have not been elucidated thoroughly, an inflammatory mechanism has been suggested to contribute to its development and progression. Moncyte chemoattractant protein (MCP)-1 is a chemokine that can attract macrophages and T cells from the circulation to the local kidney, then activate them, and(More)
PURPOSE To investigate the distribution of Ki67+ cells in breast cancer in relation to clinical-pathological parameters and prognosis. MATERIALS AND METHODS Ki67 expression status was detected in 1,086 breast cancer specimens using immunohistochemistry staining and examining the relationship between the Ki67+ cells' location. Subsequently,(More)
PURPOSE To translate the Breast Cancer and Lymphedema Symptom Experience Index (BCLE-SEI) into Chinese language and evaluate its psychometric properties among breast cancer survivors with and without lymphedema in China. METHODS The BCLE-SEI was translated from English to Chinese language using an integrative translation method. The Chinese version was(More)
Sustained stress and elevated glucocorticoid reduces neurogenesis, whereas chronic treatment with antidepressants increases neurogenesis and blocks the effects of stress. Recently, TREK-1, a two-pore domain (K2p) potassium channel, has been shown to be involved in the mechanisms of major depression. This study aimed to investigate whether TREK-1 is involved(More)
Direct millimeter-wave (MMW) holographic imaging, which provides both the amplitude and phase information by using the heterodyne mixing technique, is considered a powerful tool for personnel security surveillance. However, MWW imaging systems usually suffer from the problem of high cost or relatively long data acquisition periods for array or single-pixel(More)
