Golimumab in real-world practice in patients with ulcerative colitis:Twelve-month results

BACKGROUND The introduction of biologics has revolutionized the management of the chronic inflammatory bowel disease,ulcerative colitis(UC),with many patients experiencing significant improvements not only in their symptoms but in other outcomes relevant to individuals and society as a whole.In Germany,there are no prospective data>3 mo that assess the work productivity,daily activities and quality of life(QoL)of patients with moderate-to-severe UC treated with golimumab.AIM To assess change in work productivity,capacity for daily activities and QoL in UC patients treated with golimumab in Germany.METHODS The validated Work Productivity Activity Impairment(WPAI)Questionnaire was used to analyze the change in work productivity,the capacity for daily activities after three months(primary endpoint)and disease specific and health related QoL(HRQoL)up to 1 year(secondary endpoints).The changes in work productivity and activity impairment were evaluated every three months until month twelve compared to baseline.Disease-specific and health-related QoL were assessed with the inflammatory bowel disease questionnaire and with the short-form 12 health survey questionnaire(SF-12).RESULTS This prospective non-interventional study included 287 patients.The analysis population was comprised of 282 patients who had completed at least two visits.At baseline,61%of patients had moderate UC and 18%had severe UC.Furthermore,75%of patients worked full-time or part-time at baseline.A total of 212 patients who were employed at the start of the study(employed population)were evaluated for the primary endpoint.Golimumab significantly reduced all WPAI sub-scores compared to baseline after three,six,nine and twelve months after the start of treatment(P<0.0001).In addition,disease-specific QoL and HRQoL,as measured by the SF-12 questionnaire,improved significantly with golimumab at all evaluation times(P<0.0001 in each case vs baseline).CONCLUSION Treatment of moderate-to-severe UC with golimumab leads to significant improvements in patient´s work productivity,daily activity and QoL over twelve months.

The hypoxia-inducible factor-1α activates ectopic production of fibroblast growth factor 23 in tumor-induced osteomalacia

Tumor-induced osteomalacia （TIO） is a rare paraneoplastic syndrome in which ectopic production of fibroblast growth factor 23 （FGF23） by non-malignant mesenchymal tumors causes phosphate wasting and bone fractures. Recent studies have implicated the hypoxia-inducible factor-la （HIF-la） in other phosphate wasting disorders caused by elevated FGF23, including X-linked hypophosphatemic rickets and autosomal dominant hypophosphatemia. Here we provide evidence that HIF-la mediates aberrant FGF23 in TIO by transcriptionally activating its promoter. Immunohistochemical studies in phosphaturic mesenchymal tumors resected from patients with documented TIO showed that HIF-la and FGF23 were co-localized in spindle- shaped cells adjacent to blood vessels. Cultured tumor tissue produced high levels of intact FGF23 and demonstrated increased expression of HIF-la protein. Transfection of MC3T3-E1 and Saos-2 cells with a HIF-la expression construct induced the activity of a FGF23 reporter construct. Prior treatment of tumor organ cultures with HIF-la inhibitors decreased HIF-la and FGF23 protein accumulation and inhibited HIF-la-induced luciferase reporter activity in transfected cells. Chromatin immunoprecipitation assays confirmed binding to a HIF-la consensus sequence within the proximal FGF23 promoter, which was eliminated by treatment with a HIF-la inhibitor. These results show for the first time that HIF-la is a direct transcriptional activator of FGF23 and suggest that upregulation of HIF-la activity in TIO contributes to the aberrant FGF23 production in these patients.

It also makes an analysis of the basic and improved PAC (Production Activity Control) Architecture in the Control System for Integrated Manufacturing. The PAC Architecture and the improvement will further enhance the flexibility and adaptability of the architecture in the ever changing environment of the Shop Floor Control (SFC) Systems.

An Improved PAC Architecture for Shop Floor Information System in Digital Manufacturing

In order to overcome the weakness of the former production activity control （PAC） architecture, this paper presents an improved PAC architecture. The BIT-PAC architecture has been applied with the use of information technology. It facilitates the information flow from Shop Floor to other areas of the organization and makes the organizations more integrated and productive. This architecture also facilitates the expansion of the Shop Floor functions without disturbing the basic infrastructure. Effectiveness of the BIT-PAC architecture was checked by developing and running application software on a network PC which has supported the dynamic flow of information from Sub-Producers and Sub-Movers to other areas of organization.

APPLICATION OF IMPROVED PRODUCTION ACTIVITY CONTROL ARCHITECTURE FOR SHOP FLOOR INFORMATION SYSTEM IN DIGITAL MANUFACTURING

Shop floor control （SFC） is responsible for the coordination and control of the manufacturing physical and information flow within the shop floor in the manufacturing system. Weaknesses of the production activity control （PAC） architecture of the shop floor are addressed by the Maglica＇s new system architecture. This architecture gives rise to unlimited number of movers and producers thus evolving more complex but decentralized architecture. Beijing Institute of Technology - production activity control （BIT-PAC） architecture introduces an idea of sub-producars and sub-movers thus reducing the complexity of the architecture. All the equipments including sub-producars and sub-movers are considered to be passive in the proposed shop floor information system. The dissemination of information from sub-producers and sub-movers is done manually through a PC. Proposed BIT-PAC SFC architecture facilitates the information flow from shop floor to the other area of the organization. Effective use of interact information services （IIS） and SQL2000 is done along with the ASP.NET technology to implement the application logic. Applicability of the software based on BIT-PAC architecture is checked by running application software on a network PC that supports the dynamic flow of information from sub-producers and sub-movers to the other parts of the organization. Use of software is also shown at the end for BIT training workshop thus supporting the use of SFC architecture for similar kind of environments.

Formation and removal of active oxygen species for the non-catalytic CO oxidation on Au/TiO_2 catalysts

Applying quantitative temporal analysis of products reactor measurements, we studied the reactive removal of active oxygen present on Au/TiO2 catalysts after calcination at elevated temperatures （400 ＆#176;C） by CO pulses and its replenishment by O2 pulses at 80 ＆#176;C, focusing on the nature of the active oxygen species. In contrast to previous studies, which mainly focused on and clarified the nature of the active oxygen species for the catalytic CO oxidation, which is reversibly formed and replenished under typical reaction conditions, this study demonstrates that directly after calcina‐tion an additional oxygen species is present. This species is also active for the CO oxidation, but it is not or only very little formed under typical reaction conditions. Implications of these results on the mechanistic understanding of the CO oxidation on Au/TiO2, in particular on the role of different active oxygen species, will be discussed.

Textile Industry to See Slow Growth Analysis of industrial production activities in the first four months

Textile industry, a major driver of the Chinese economy, has fallen victim to the global credit crisis and weaker demand. In the first two months, the output, sale, investment and export of textile industry grew at a slower pace than last year. But things began to pick up after that as the economy slowly begins to recover since March. Signif icant gains at that time will be hard to come by, and won’t be nearly enough to prevent other sizeable slippage in overall textile and apparel activity.

ACTIVATION OF BOVINE FACTOR IX BY THE REACTION PRODUCT OF BOVINE FACTOR VII AND HUMAN TISSUE FACTOR

A study was carried out on the alternate activation of factor IX （FIX） by bovine FVII and human tissue factor （TF） rather than by activated factor XI （FXI）. The reaction product of bovine FVII and human TF functioned as a FIX activator in the assay system used. Published studies suggest that in the presence of Caions, the complex of human FVII-TF readily activates both human FIX and human FX,and at low TF concentrations, FIX appears to be the preferred substrate for the reaction product of FVII and TF. This may explain the discrepancy between the mild bleeding of hereditary FXI deficiency and the severe bleeding of hereditery FIX deficieney. The results obtained with bovine FVII and a crude human TF preparation confirm that at low TF concentrations,bovine FIX is the preferred substrate rather than FX. At higher TF concentrations, bovine FX was rapidly activated.

Potential acute effects of suspended aluminum nitride (AlN) nanoparticles on soluble microbial products (SMP) of activated sludge

The study aims to identify the potential acute effects of suspended aluminum nitride（Al N）nanoparticles（NPs） on soluble microbial products（SMP） of activated sludge.Cultured activated sludge loaded with 1,10,50,100,150 and 200 mg/L of Al N NPs were carried out in this study.As results showed,Al N NPs had a highly inverse proportionality to bacterial dehydrogenase and OUR,indicating its direct toxicity to the activated sludge viability.The toxicity of Al N NPs was mainly due to the nano-scale of Al N NPs.In SMP,Al N NPs led to the decrease of polysaccharide and humic compounds,but had slight effects on protein.The decrease of tryptophan-like substances in SMP indicated the inhibition of Al N NPs on the bacterial metabolism.Additionally,Al N NPs reduced obviously the molecular weight of SMP,which might be due to the nano-scale of Al N.
