Photorhabdus luminescens is a symbiont of nematodes and a broad-spectrum insect pathogen. The complete genome sequence of strain TT01 is 5,688,987 base pairs (bp) long and contains 4,839 predicted protein-coding genes. Strikingly, it encodes a large number of adhesins, toxins, hemolysins, proteases and lipases, and contains a wide array of antibiotic(More)
On the line and its tensor products, Fekete points are known to be the Gauss–Lobatto quadrature points. But unlike high-order quadrature, Fekete points generalize to non-tensor-product domains such as the triangle. Thus Fekete points might serve as an alternative to the Gauss–Lobatto points for certain applications. In this work we present a new algorithm(More)
In vitro recombinant receptor-reporter gene assays have been used to assess and rank the potency of chemicals and complex mixtures suspected of possessing estrogen and (or) aryl hydrocarbon receptor (AhR) mediated activity. The environmental estrogen (E2) bioassay consists of a Gal4-human estrogen receptor chimeric construct (Gal4-HEGO) and a Gal4-regulated(More)
The genome of the Autographa californica Multinucleocapsid Polyhedrosis Virus (AcMNPV) contains nine interspersed homologous regions (hrs) that function as potent enhancer sequences when linked in cis to either viral or heterologous RNA polymerase II-dependent promoters. Their activity is strongly increased by the binding of the major immediate early viral(More)
Class II genes of the human major histocompatibility complex (MHC) are polymorphic. Allelic variation of the coding region of these genes is involved in the antigen presentation and is associated with susceptibility to certain autoimmune diseases. The DR region is unique among human class II regions in that multiple DRB genes are expressed. Differential(More)
The first prophylactic human immunodeficiency virus type 1 (HIV-1) vaccine trial in Africa, with a clade B immunogen, is currently under way in Uganda, in a region where clades A and D are endemic. The use of a B clade vaccine is based on anticipated cross-recognition of endemic strains of HIV-1 in Uganda, but, in fact, little is known about the cytotoxic T(More)
Scleroderma is an umbrella term for a spectrum of rare and complex autoimmune connective tissue diseases, the cause and pathogenesis of which is only partially defined. Scleroderma can be divided into two main subgroups--systemic and localized--but the hallmark of both is skin fibrosis. As yet no drug has been found to be effective in reversing the disease(More)
We have identified cuticular pheromones that sustain the integrity of the six Drosophila paulistorum semispecies. Hexane extracts of male and female cuticles were separated on a silica gel column and analyzed using gas chromatography/mass spectrometry. Both sexes of each of the six semispecies have the same fifteen major cuticular components, all(More)
