A series of inhibitors with a squaramide core was synthesized following its discovery in a high-throughput screen for novel inhibitors of a transcription-coupled translation assay using Escherichia coli S30 extracts. The inhibitors were inactive when the plasmid substrate was replaced with mRNA, suggesting they interfered with transcription. This was(More)
During development, hematopoiesis and neovascularization are closely linked to each other via a common bipotent stem cell called the hemangioblast that gives rise to both hematopoietic cells and endothelial cells. In postnatal life, this functional connection between the vasculature and hematopoiesis is maintained by a subset of hematopoietic progenitor(More)
BACKGROUND Surgery followed by adjuvant radiotherapy is a well-established treatment paradigm for brain metastases. OBJECTIVE To examine the effect of postsurgical whole-brain radiotherapy (WBRT) or localized radiotherapy (LRT), including stereotactic radiosurgery and intraoperative radiotherapy, on the rate of recurrence both local and distal to the(More)
Pulmonary arterial hypertension (PAH) is a heterogeneous disease characterized by severe angiogenic remodeling of the pulmonary artery wall and right ventricular hypertrophy. Thus, there is an increasing need for novel biomarkers to dissect disease heterogeneity, and predict treatment response. Although β-adrenergic receptor (βAR) dysfunction is well(More)
We present the discovery and optimization of a novel series of bacterial topoisomerase inhibitors. Starting from a virtual screening hit, activity was optimized through a combination of structure-based design and physical property optimization. Synthesis of fewer than a dozen compounds was required to achieve inhibition of the growth of(More)
TO THE EDITOR: Odden and colleagues (1) did not include stroke in their estimate of the cost-effectiveness of statins for primary prevention in adults aged 75 years or older. This results in an underestimate of the benefits of statins in this age group and an overestimate of their costs. Stroke increases dramatically with advancing age and accounts for a(More)
BACKGROUND In recent years, the population of patients with pulmonary arterial hypertension (PAH) has changed dramatically, including more advanced age at diagnosis. We hypothesized that older patients have a distinct clinical profile with different disease characteristics and response to intervention. METHODS All previously published treatment studies(More)
Second generation hepatitis C virus (HCV) Elisas are currently in use in Europe and have been submitted for approval in the United States. These new assays contain additional antigens from the putative nucleocapsid and NS-3 regions of the HCV genome in addition to the c100-3 antigen present in first generation Elisas. A supplementary test, the second(More)
With increasing emergence of multi-drug resistant infections, there is a dire need for new classes of compounds that act through unique mechanisms. In this work, we describe the discovery and optimization of a novel series of inhibitors of bacterial methionine aminopeptidase (MAP). Through a high-throughput screening campaign, one azepinone amide hit was(More)
Treatment of duodenal ulcer with the H2-receptor antagonist ranitidine, 150 mg twice daily has been assessed in a double-blind, placebo controlled study at seven centres in the United Kingdom. One hundred-and-twenty-nine patients entered the trial with endoscopically confirmed duodenal ulcer. Five patients did not comply with the protocol and were excluded(More)
