Also, It describes the operations of the four core functions: land tenure, land valuation, land use, and land development in land administration under a single sustainable national land policy, underpinned by spatial information under the e-Governance mechanism. Further, the paper identifies the stakeholders and their main responsibilities in each of the four core functions with the current issues in sharing information across stakeholders. Finally, the paper describes setting up a Land administration entity thereby empowering the LAC and introduces spatial information layers at different resolution levels in a centralized land administration spatial database to keep track of all land transactions carried out by each stakeholder. This approach will enable the top-level decision-making authority (the central level) to manage all land-related activities under one platform to contribute towards the sustainable land development of the country. It is proposed to implement this approach as a pilot activity in the district of Colombo and expand it in the entire country gradually with its output.展开更多

Together with the 2003 Mass Housing Act, 14 legal regulations were enacted between 2002 and 2008 to expand the field of activity and increase the funds of TOKI (Governmental Mass Housing Administration) which was already established during ANAP (the Motherland Party) Government in 1980s. As a result of those regulations, TOKI, as the "latest goddess of the construction myth", became the only authorized organization in the field of housing and land production in AKP's cities. It acquired new duties from generating profit-oriented projects to protecting historical texture, and it was authorized to make and approve zoning plans for the lands and plots handed over to TOKI of the last government (the Justice and Welfare Party) created as an investor-entrepreneur-contractor-performer group. This paper's aim is to indicate the transformation of TOKI foundation during the last twenty years, and also to prove that TOKI, as a governmental profit-oriented design tool, has demolished the unique DNA/morphological textures of the contemporary Turkish big cities by producing low profiled similar architecture and urbanity in the recent past.展开更多

OBJECTIVE: To examine the effects of intraplantar and intrathecal injection of Glu on c-Fos expression in the L5 spinal cord dorsal horn Ⅰ/Ⅱ and Ⅲ/Ⅳ layers after spinal nerve ligation, and to study the effects of the N-methyI-D-aspartic acid (NMDA) receptor antagonist, D-2-amino-5-phosphonopentanoate (D-AP5), and a selective group I mGluR antagonist, 7-hydroyiminocyclo propan[a]chromen-lacarboxylic acid ethyl ester (cpccoEt). DESIGN, TIME AND SETTING: A randomized, controlled animal study was performed at the Department of Pharmacology, Oral Anatomy, and Neurobiology, Osaka University Graduate School of Dentistry, from December 2005 to December 2006. MATERIALS: Glu (5 μmol), D-AP5 (50 nmot) and cpccoEt (250 nmol) were provided by Wako Pure Chemical Industries, Osaka, Japan, and diluted in saline (50 μL). The pH of all solutions was adjusted to 7.4. METHODS: Twelve rats were randomly divided into sham operation (n = 6) and spinal nerve ligation (SNL; n = 6) groups for behavioral assessments of neuropathic pain after ligation surgery of the left L5-6 nerve segment. Another 60 rats were randomly divided into sham operation, SNL, saline-intraplantar, saline-intrathecal, Glu-intraplantar, Glu-intrathecal, D-AP5-intrathecal, Glu-D-AP5-intrathecal, cpccoEt-intrathecal, and Glu-cpccoEt-intrathecal groups, with 6 rats in each group. All groups except sham operation group received a similar SNL. On day 14, rats received a 50-μL injection of saline, Glu, D-AP5, and/or cpccoEt into the left intraplantar or intrathecal L5-4 segments. MAIN OUTCOME MEASURES: The number of c-Fos positive neurons in both Ⅰ/Ⅱ and Ⅲ/Ⅳ spinal layers at L6 was observed using immunohistochemistry 2 hours after administration. RESULTS: (1) SNL increased the level of c-Fos expression in two sides of the spinal cord, particularly on Ⅲ/Ⅳ spinal layers of the ligated side. (2) Intraplantar or intrathecal administration of saline significantly increased the c-Fos labeled neurons in Ⅰ/Ⅱ spinal layers of the ligated side, compared with SNL alone (P 〈 0.01). (3) Intraplantar Glu (5 μmol) increased the number of c-Fos positive neurons in Ⅰ/Ⅱ spinal layers compared with intraplantar saline (P〈 0.01). (4) The number of c-Fos neurons in Ⅰ/Ⅱ spinal layers on both the ipsilateral and contralateral side after intraplantar Glu was lower than intrathecal Glu (P〈 0.01), with a 3-fold higher induction by intrathecal Glu. (5) Co-administration of D-AP5 or cpccoEt reduced the effects of intrathecal Glu (P 〈 0.01). CONCLUSION: Intrathecal Glu increases c-Fos expression more than intraplantar Glu. Antagonists of NMDA and group I mGluRs block this effect.展开更多

However, evidence of intraoperative fluid(IOF) administration affecting clinical outcomes following McKeown esophagogastrectomy remains limited. This study investigated the impact of IOF on clinical outcomes after McKeown esophagogastrectomy.Methods: Patients who underwent McKeown esophagogastrectomy between July 2013 and July 2016 were identified. Preoperative, intraoperative and postoperative variables for each eligible patient were retrospectively collected from our electronic medical records and anesthetic records. IOF rates were determined and their relationships to postoperative clinical outcomes were compared.Results: A total of 546 patients were enrolled in the analysis. The median IOF rate was 8.87 mL/kg/h. We divided the patients into two groups: a low fluid volume group(LFVG <8.87 mL/kg/h, n=273) and a high fluid volume group(HFVG ≥8.87 mL/kg/h, n=273). No statistically significant differences in postoperative clinical outcomes were found between LFVG and HFVG either before or after propensity score matching.Conclusions: No effect of IOF administration on clinical outcomes in patients undergoing McKeown esophagogastrectomy was identified. Further high-quality studies examining the influence of IOF administration on clinical outcomes following McKeown esophagogastrectomy are still needed.展开更多

The oxidative enzymes cytochrome P450 (CYP)3A and the drug efflux pump P-glycoprotein (P-gp) are two potential factors in the processes of metabolism. Pharmacogenetic study of immunosuppressive drugs has focused on these two enzymes. This review was undertaken to assess the role of single nuclear polymorphisms (SNPs) of these two enzymes in the individual administration of immunosuppressive drugs. DATA SOURCES: An English-language literature search was made using MEDLINE for articles on CYP3A and P-gp in organ transplantation. RESULTS: The SNPs of CYP3A and P-gp are closely correlated to the large variations of cyclosporine and tacrolimus dosage between different patients, although conflicting results were obtained by some authors. CONCLUSIONS: More studies should be conducted to elucidate further the pharmacogenetics of immunosuppressive drugs in organ transplantation, a deep understanding of which would provide an important step toward drug regimen individualization in the posttransplant therapy.展开更多

Based on the proposed model, the performances of two time scales for bursting oscillations in the HTGS are investigated and the effect of periodic excitation of frequency disturbance is analyzed by using the bifurcation diagrams, time waveforms and phase portraits. We find that stability and operational characteristics of the HTGS change with the value of system parameter kd. Furthermore, the comparative analyses for the effect of the bursting oscillations on the system with different amplitudes of the periodic excitation a are carried out. Meanwhile, we obtain that the relative deviation of the mechanical torque mt rises with the increase of a. These methods and results of the study, combined with the performance of two time scales and the fast-slow coupled engineering model, provide some theoretical bases for investigating interesting physical phenomena of the engineering system.展开更多

文摘BACKGROUND: Injection of glutamate (Glu) in normal animals can cause neuronal c-Fos expression; however, whether Glu can induce spinal neuronal c-Fos expression in pain models is unclear. OBJECTIVE: To examine the effects of intraplantar and intrathecal injection of Glu on c-Fos expression in the L5 spinal cord dorsal horn Ⅰ/Ⅱ and Ⅲ/Ⅳ layers after spinal nerve ligation, and to study the effects of the N-methyI-D-aspartic acid (NMDA) receptor antagonist, D-2-amino-5-phosphonopentanoate (D-AP5), and a selective group I mGluR antagonist, 7-hydroyiminocyclo propan[a]chromen-lacarboxylic acid ethyl ester (cpccoEt). DESIGN, TIME AND SETTING: A randomized, controlled animal study was performed at the Department of Pharmacology, Oral Anatomy, and Neurobiology, Osaka University Graduate School of Dentistry, from December 2005 to December 2006. MATERIALS: Glu (5 μmol), D-AP5 (50 nmot) and cpccoEt (250 nmol) were provided by Wako Pure Chemical Industries, Osaka, Japan, and diluted in saline (50 μL). The pH of all solutions was adjusted to 7.4. METHODS: Twelve rats were randomly divided into sham operation (n = 6) and spinal nerve ligation (SNL; n = 6) groups for behavioral assessments of neuropathic pain after ligation surgery of the left L5-6 nerve segment. Another 60 rats were randomly divided into sham operation, SNL, saline-intraplantar, saline-intrathecal, Glu-intraplantar, Glu-intrathecal, D-AP5-intrathecal, Glu-D-AP5-intrathecal, cpccoEt-intrathecal, and Glu-cpccoEt-intrathecal groups, with 6 rats in each group. All groups except sham operation group received a similar SNL. On day 14, rats received a 50-μL injection of saline, Glu, D-AP5, and/or cpccoEt into the left intraplantar or intrathecal L5-4 segments. MAIN OUTCOME MEASURES: The number of c-Fos positive neurons in both Ⅰ/Ⅱ and Ⅲ/Ⅳ spinal layers at L6 was observed using immunohistochemistry 2 hours after administration. RESULTS: (1) SNL increased the level of c-Fos expression in two sides of the spinal cord, particularly on Ⅲ/Ⅳ spinal layers of the ligated side. (2) Intraplantar or intrathecal administration of saline significantly increased the c-Fos labeled neurons in Ⅰ/Ⅱ spinal layers of the ligated side, compared with SNL alone (P 〈 0.01). (3) Intraplantar Glu (5 μmol) increased the number of c-Fos positive neurons in Ⅰ/Ⅱ spinal layers compared with intraplantar saline (P〈 0.01). (4) The number of c-Fos neurons in Ⅰ/Ⅱ spinal layers on both the ipsilateral and contralateral side after intraplantar Glu was lower than intrathecal Glu (P〈 0.01), with a 3-fold higher induction by intrathecal Glu. (5) Co-administration of D-AP5 or cpccoEt reduced the effects of intrathecal Glu (P 〈 0.01). CONCLUSION: Intrathecal Glu increases c-Fos expression more than intraplantar Glu. Antagonists of NMDA and group I mGluRs block this effect.
文摘Objective: Fluid therapy is one of the key components of perioperative management. However, evidence of intraoperative fluid(IOF) administration affecting clinical outcomes following McKeown esophagogastrectomy remains limited. This study investigated the impact of IOF on clinical outcomes after McKeown esophagogastrectomy.Methods: Patients who underwent McKeown esophagogastrectomy between July 2013 and July 2016 were identified. Preoperative, intraoperative and postoperative variables for each eligible patient were retrospectively collected from our electronic medical records and anesthetic records. IOF rates were determined and their relationships to postoperative clinical outcomes were compared.Results: A total of 546 patients were enrolled in the analysis. The median IOF rate was 8.87 mL/kg/h. We divided the patients into two groups: a low fluid volume group(LFVG <8.87 mL/kg/h, n=273) and a high fluid volume group(HFVG ≥8.87 mL/kg/h, n=273). No statistically significant differences in postoperative clinical outcomes were found between LFVG and HFVG either before or after propensity score matching.Conclusions: No effect of IOF administration on clinical outcomes in patients undergoing McKeown esophagogastrectomy was identified. Further high-quality studies examining the influence of IOF administration on clinical outcomes following McKeown esophagogastrectomy are still needed.

文摘BACKGROUND: The immunosuppressive drugs used worldwide have a narrow therapeutic index, which results in a need to individualize the dose regimen for different recipients. The oxidative enzymes cytochrome P450 (CYP)3A and the drug efflux pump P-glycoprotein (P-gp) are two potential factors in the processes of metabolism. Pharmacogenetic study of immunosuppressive drugs has focused on these two enzymes. This review was undertaken to assess the role of single nuclear polymorphisms (SNPs) of these two enzymes in the individual administration of immunosuppressive drugs. DATA SOURCES: An English-language literature search was made using MEDLINE for articles on CYP3A and P-gp in organ transplantation. RESULTS: The SNPs of CYP3A and P-gp are closely correlated to the large variations of cyclosporine and tacrolimus dosage between different patients, although conflicting results were obtained by some authors. CONCLUSIONS: More studies should be conducted to elucidate further the pharmacogenetics of immunosuppressive drugs in organ transplantation, a deep understanding of which would provide an important step toward drug regimen individualization in the posttransplant therapy.

文摘Bortezomib,the first potent therapeutic proteasome inhibitor,has been suggested as a standard care in patients with newly diagnosed and relapsed multiple myeloma(MM).However,evidence bearing on the efficacy and safety of subcutaneous(SC) versus intravenous(IV) administration of bortezomib for MM patients is controversial.Randomised controlled trials(RCTs) and observational studies were enrolled in our meta-analysis to investigate the efficacy and safety of bortezomib via SC vs.IV administration on MM patients.Sixteen trials with a total of 2575 patients with MM(SC,n=1191;IV,n=1384) were included in our meta-analysis.There were no significant differences between these two arms regarding overall response rate(ORR),complete response(CR),or very good partial response(VGPR).The pooled RRs for rate of adverse events(AEs),such as thrombocytopenia and bortezomib-induced peripheral neuropathy(BIPN),were 0.79(95% CI:0.68–0.92) and 0.63(95% CI:0.51–0.79),respectively.Moreover,there was much more largely decreased incidence of grade 3 and higher thrombocytopenia and BIPN in bortezomib SC administration than IV route.In general,alternative SC administration should be considered instead of IV administration in use of bortezomib for patients with MM.

文摘A fast-slow coupled model of the hydro-turbine governing system (HTGS) is established by introducing frequency disturbance in this paper. Based on the proposed model, the performances of two time scales for bursting oscillations in the HTGS are investigated and the effect of periodic excitation of frequency disturbance is analyzed by using the bifurcation diagrams, time waveforms and phase portraits. We find that stability and operational characteristics of the HTGS change with the value of system parameter kd. Furthermore, the comparative analyses for the effect of the bursting oscillations on the system with different amplitudes of the periodic excitation a are carried out. Meanwhile, we obtain that the relative deviation of the mechanical torque mt rises with the increase of a. These methods and results of the study, combined with the performance of two time scales and the fast-slow coupled engineering model, provide some theoretical bases for investigating interesting physical phenomena of the engineering system.
