Objectives: Parkinson's disease (PD) ranks the second among the neurodegenerative disorders. Proteins involved in Parkinson's disease (PD) have been investigated but none as the diagnostic markers in blood. Design and methods: In this study, we applied a proteomic strategy, by utilizing two-dimensional electrophoresis and mass spectrometry, to analyze two sample pools of plasma from the healthy individuals and PD subjects. Results: IgGκL and human serum amyloid P component (SAP) were found differentially expressed between these pools. SAP level increased by approximately 5-fold in PD samples, and the ELISA procedure revealed a significant (P< 0.001) increase in SAP concentration (65.9 ± 18.7 μg/mL) in the plasma of PD subjects (healthy individuals, 35.0 ± 12.5 μg/mL), with sensitivity of 94.1% and specificity of 87.5%. Conclusion: Our results indicated a potential feasibility of plasma SAP as a marker to approach PD. © 2011 The Canadian Society of Clinical Chemists. Source

Our previous report has shown that berberine effectively inhibits LPS- and IFN-γ-induced neuroinflammation in microglia cells. Recently, we also reported that HO-1 (Heme oxygenase-1) may be a therapeutic target to regulate neuroinflammation in microglia cells. The present study examined the ability of berberine, the major constituents of Chinese herb Rhizoma coptidis, to induce expression of HO-1, and analyzed its signaling mechanism in rat brain astrocytes. HO-1 is known as an antioxidant enzyme which helps to protect against cellular damage and maintains tissue homeostasis. Here, we found that berberine increased HO-1 mRNA and protein expression concentration- and time-dependently. In addition, berberine-induced HO-1 expression was attenuated by PI 3-kinase (phosphatidylinositol 3-kinase) inhibitors LY294002 and wortmannin, and an AKT inhibitor. Treatment of astrocytes with berberine also induced p85 (PI 3-kinase) and AKT phospholation, and increased AKT kinase activity. Berberine also increased NF-E2-related factor-2 (Nrf2) accumulation in the nucleus and increased Nrf2-DNA binding activity as determined by the EMSA (electrophoretic mobility shift assay). Moreover, berberine-induced increase of Nrf2-DNA binding activity was reduced by PI 3-kinase and AKT inhibitors. Berberine-increased HO-1-luciferase activity was also inhibited by co-transfection with dominant-negative (DN) mutants of p85 and AKT. Moreover, berberine-mediated increase of HO-1 transcriptional activity and protein expression were reduced by transfection with siRNA againt Nrf2. These findings suggest that berberine-increased HO-1 expression is mediated by Nrf2 activation through the PI 3-kinase/AKT pathway in astrocytes. Thus, berberine may be useful as a therapeutic agent for the treatment of neuroinflammation-associated disorders. © 2011 Elsevier B.V. All rights reserved. Source

Ghrelin is a newly discovered gastric peptide which stimulates food intake, energy balance, and growth hormone release. Recent reports have also shown that circulating ghrelin can efficiently reach the brain. However, the molecular mechanisms and pathophysiologic roles underlying ghrelin-induced glioma migration remain unclear. Glioma is the most common primary adult brain tumor with poor prognosis because of the spreading of tumor cell to the other regions of brain easily. In present study, we found that application of recombinant human ghrelin enhances the glioma cell migration in both rat C6 and human U251 cells. Ghrelin and its receptor GHS-R (growth hormone secretagogue receptor) are expressed in a wide variety of tissues and cell types, including various cancer cells. However, little is known about the expression of ghrelin or GHS-R in brain tumors. Here, we found that ghrelin increased GHS-R receptor up-regulation, and the enhancement of ghrelin-induced glioma cell motility markedly inhibited by a GHS-R antagonist. In addition, ghrelin-mediated migration was attenuated by treatment of CaMKII inhibitor, and AMPK inhibitors and pre-transfection with AMPK siRNA. Moreover, ghrelin stimulation also increased the phosphorylation of CaMKII and AMPK. Treatment with three different types of NF-κB inhibitors or pre-transfection with KM-IKKα, or KM-IKKβ also reduced ghrelin-induced glioma cell migration. Moreover, treatment of ghrelin also induced IKKα/β activation, IκBα phosphorylation, p65 phosphorylation at Ser 536, and increased NF-κB-DNA binding activity and κB-transcriptional activity. These results indicate that ghrelin enhances migration of glioma cells is mainly regulated by the GHS-R, CaMKII, AMPK, and NF-κB pathway. Copyright © 2011 Wiley-Liss, Inc. Source

As information and communication technology applied to telecare has become a trend in elder care services, evaluation of the program is vital for further program design and development. This study evaluated the variables influencing the use of a telecare service program by the elderly. A questionnaire survey was used to explore the relationship between quality of life and technology acceptance of a telecare program in Taiwan. In addition, open-ended questions were used to elicit qualitative information regarding the experience of technology use. The results revealed that elderly persons with better social welfare status and health condition, who used the device frequently, had higher quality of life and accepted technology use. The correlation results also indicated that elderly persons who perceived telecare as useful in solving health problems, had the intention to use the program, and were willing to continue use, also had a better perception toward quality of life regarding their interpersonal relationships and living environment. Nonetheless, cost may be an issue that will impede their willingness to use the technology in care service. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source

Subcutaneous intravenous infusion port (SIIP) has become an increasingly and widely adopted technique in the management of oncology patients. This route has been used not only for chemotherapy but also for parenteral nutrition provision, blood transfusion, medication administration, blood sample collection, hemodialysis, and so on. This system provides a safe vascular access with low complication rate which helps preventing patients from vascular infection and catheter associated thrombosis. In this study, we reviewed 1247 cases of breast cancer patients that had subcutaneous intravenous infusion port implanted for chemotherapy in our general surgery department from 1990 to 2008. The result indicates that complication decreases as our technique and experience mature. We hereby share our accrued experience and improved technique, hoping to be of help to young surgeons. © 2010 Elsevier Ltd. All rights reserved. Source
