The Pseudomonas aeruginosa enzyme GDP-mannose dehydrogenase (GMD) is encoded by the algD gene, and previous genetic studies have indicated that it is a key regulatory and committal step in the biosynthesis of the polysaccharide alginate. In the present study the algD gene has been cloned into the broad-host-range expression vector pMMB66EH and GMD overexpressed in mucoid and genetically-related...
A range of monthly series are currently available giving indications of short-term movements in output in the UK. The main aim of this paper is to suggest a formal and coherent procedure for grossing these monthly data up to represent the whole of GDP. Although the resultant estimates of GDP would be worse than those obtained by direct measurement, they should be more satisfactory than simply m...
Nighttime light data offer a unique view of the Earth’s surface and can be used to estimate the spatial distribution of gross domestic product (GDP). Historically, using a simple regression function, the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) has been used to correlate regional and global GDP values. In early 2013, the first global Suomi National Polar...
Newspaper advertising expenditures depend more strongly on economic development than advertising spent in other media. Gross domestic product (GDP), therefore, predicts ad spending better in countries where newspapers are an important advertising medium. GDP also predicts ad spending better in countries where a larger proportion of GDP is spent on advertising. Intermedia competition, on the oth...
BACKGROUND The Global Vaccine Action Plan will require, inter alia, the mobilization of financial resources from donors and national governments - both rich and poor. Vaccine Procurement Assistance (VPA) and Vaccine Procurement Baseline (VPB) are two metrics that could measure government performance and track resources in this arena. VPA is proposed as a new subcategory of Official Development ...
To survive in its sand fly vector, the trypanosomatid protozoan parasite Leishmania first attaches to the midgut to avoid excretion, but eventually it must detach for transmission by the next bite. In Leishmania major strain Friedlin, this is controlled by modifications of the stage-specific adhesin lipophosphoglycan (LPG). During differentiation to infective metacyclics, d-arabinopyranose (d-A...
SelB is a specialized translation factor that binds GTP and GDP and delivers selenocysteyl-tRNA (Sec-tRNA(Sec)) to the ribosome. By analogy to elongation factor Tu (EF-Tu), SelB is expected to control the delivery and release of Sec-tRNA(Sec) to the ribosome by the structural switch between GTP- and GDP-bound conformations. However, crystal structures of SelB suggested a similar domain arrangem...
PURPOSE For patients with relapsed or refractory aggressive lymphoma, we hypothesized that gemcitabine-based therapy before autologous stem-cell transplantation (ASCT) is as effective as and less toxic than standard treatment. PATIENTS AND METHODS We randomly assigned 619 patients with relapsed/refractory aggressive lymphoma to treatment with gemcitabine, dexamethasone, and cisplatin (GDP) or...
Heterotrimeric G protein α subunits are activated upon exchange of GDP for GTP at the nucleotide binding site of Gα, catalyzed by guanine nucleotide exchange factors (GEFs). In addition to transmembrane G protein-coupled receptors (GPCRs), which act on G protein heterotrimers, members of the family cytosolic proteins typified by mammalian Ric-8A are GEFs for Gi/q/12/13-class Gα subunits. Ric-8A...
