We investigated compounds related to the previously reported antistaphyloccocal agent AVE6971 in an effort to attenuate inhibition of hERG potassium channel current that has been noted for this and related antibacterial drug classes. While most modifications of the original thiophene group compromised antibacterial activity, one selenophene analogue displayed (i) improved activity against the primary target enzyme DNA gyrase, (ii) similar activities against a panel of MRSA clinical isolates, and (iii) reduced hERG channel inhibition. 相似文献

The initial antibody response to HIV-1 is targeted to envelope (Env) gp41, and is nonneutralizing and ineffective in controlling viremia. To understand the origins and characteristics of gp41-binding antibodies produced shortly after HIV-1 transmission, we isolated and studied gp41-reactive plasma cells from subjects acutely infected with HIV-1. The frequencies of somatic mutations were relatively high in these gp41-reactive antibodies. Reverted unmutated ancestors of gp41-reactive antibodies derived from subjects acutely infected with HIV-1 frequently did not react with autologous HIV-1 Env; however, these antibodies were polyreactive and frequently bound to host or bacterial antigens. In one large clonal lineage of gp41-reactive antibodies, reactivity to HIV-1 Env was acquired only after somatic mutations. Polyreactive gp41-binding antibodies were also isolated from uninfected individuals. These data suggest that the majority of gp41-binding antibodies produced after acute HIV-1 infection are cross-reactive responses generated by stimulating memory B cells that have previously been activated by non-HIV-1 antigens. 相似文献

Obesity has become a serious global health issue affecting both adults and children. Recent devolopments in world demographics and declining health status of the world's population indicate that the prevalence of obesity will continue to increase in the next decades. As a disease, obesity has deleterious effects on metabolic homeostasis, and affects numerous organ systems including heart, kidney and the vascular system. Thus, obesity is now regarded as an independent risk factor for atherosclerosis-related diseases such as coronary artery disease, myocardial infarction and stroke. In the arterial system, endothelial cells are both the source and target of factors contributing to atherosclerosis. Endothelial vasoactive factors regulate vascular homeostasis under physiological conditions and maintain basal vascular tone. Obesity results in an imbalance between endothelium-derived vasoactive factors favouring vasoconstriction, cell growth and inflammatory activation. Abnormal regulation of these factors due to endothelial cell dysfunction is both a consequence and a cause of vascular disease processes. Finally, because of the similarities of the vascular pathomechanisms activated, obesity can be considered to cause accelerated, 'premature' vascular aging. Here, we will review some of the pathomechanisms involved in obesity-related activation of endothelium-dependent vasoconstriction, the clinical relevance of obesity-associated vascular risk, and therapeutic interventions using 'endothelial therapy' aiming at maintaining or restoring vascular endothelial health.

The aim of this study was to investigate the complex association pattern of the extended major histocompatibility complex (xMHC) region with rheumatoid arthritis (RA) susceptibility to identify effects independent of HLA-DRB1. A total of 1804 RA cases and 1474 controls were included. High-resolution HLA-DRB1 typing was performed. Subjects were genotyped for 1546 single-nucleotide polymorphisms (SNPs) using Affymetrix GeneChip 500?K (Santa Clara, CA, USA) as part of the Wellcome Trust Case Control Consortium Study. Statistical analysis was carried out using PLINK. To avoid confounding by RA-associated HLA-DRB1 alleles, we analyzed xMHC SNPs using a data set with pairwise matching of cases and controls on DRB1 genotypes. A total of 594 case-control pairs with identical DRB1 genotypes were identified. After this adjustment, 104 SNPs remained significantly associated with RA (P<0.05), suggesting that additional RA loci independent of HLA-DRB1 can be found in the xMHC region. Of these, four loci showed the strongest associations with RA (P<0.005): ZNF391, the olfactory receptor (OR) gene cluster, C6orf26-RDBP and HLA-DPB1-COL11A2. An additional locus mapping to the BTN (butyrophilin) cluster showed independent association with RA in anti-cyclic citrullinated peptide-positive patients exclusively. We have validated the previously described independent association of the HLA-DPB1-COL11A2 locus with RA. In addition, association with three novel independent RA loci in the xMHC region (ZNF391, OR2H1 and C6orf26-RDBP) has been detected. 相似文献

barton d . & mashlan w. (2011) Journal of Nursing Management 19, 943–949 An advanced nurse practitioner-led service – consequences of service redesign for managers and organizational infrastructure Aim A service review of a secondary care advanced nurse practitioner-led service. Background An acute hospital-based elderly care rehabilitation service evolved over a 9-year period from a traditional consultant/junior doctor configuration to a consultant/advanced nurse practitioner configuration. The review evaluated the advanced nurse practitioner team’s role in the clinical setting, and the constraints experienced as a result of the traditions of the hospital organization. Evaluation The review drew its conclusions from opinion data collected from 38 professionals and non-professionals within the rehabilitation service. Key issues The organizational infrastructure and traditions that had an impact on service delivery by the advanced nurse practitioner team. There is a demand for senior management to act on developmental constraints. Conclusions The advanced nurse practitioner-led rehabilitation service was fit for purpose and an emerging model of a non-medical led care. However, important organizational constraints were identified. Implications for nursing management An advanced nurse practitioner team, working in collaboration with medical consultants, was a model for future service redesign in the acute hospital setting. Nevertheless, it presented challenges to senior health-care managers on current organizational infrastructures. 相似文献
