The potential for the non-coding intergenic rDNA spacer (IGS) to DNA fingerprint Giardia duodenalis isolates was investigated. Conserved PCR primers, specific for the flanking large and small rDNA genes, were used to amplify the IGS from 52 in vitro-cultured Giardia isolates. Four distinct IGS-PCR size groups (1.35-1.6 kb) were observed, which correlated closely with the major genetic assemblag...

Informal urban green-space (IGS) such as vacant lots, brownfields and street or railway verges is receiving growing attention from urban scholars. Research has shown IGS can provide recreational space for residents and habitat for flora and fauna, yet we know little about the quantity, spatial distribution, vegetation structure or accessibility of IGS. We also lack a commonly accepted definitio...

The diversity of Bradyrhizobium strains nodulating three cowpea (Vigna unguiculata L. Walp.) cultivars in favorable and water-limited conditions occuring at flowering was analysed. PCRRestriction Fragment Length Polymorphism (PCR-RFLP) analysis of 16S-23S rDNA intergenic spacer region (IGS) directly applied on 85 crushed nodules distinguished four genetic profiles, IGS types I, II, III and IV. ...

Fusarium Head Blight is an important wheat disease in the Argentine Pampas region, being Fusarium graminearum the predominant pathogen. DNA polymorphism of the isolates was analyzed by IGS-RFLP and ISSR. IGS-RFLP and ISSR profiling were carried out using six endonucleases and eight primers, respectively. IGS-RFLP yielded 41 bands, 30 of which were polymorphic while ISSR produced 87 bands with 4...

BACKGROUND: The inositol glycans (IGs) are glycolipid-derived carbohydrates produced by insulin-sensitive cells in response to insulin treatment. IGs exhibit an array of insulin-like activities including stimulation of lipogenesis, glucose transport and glycogen synthesis, suggesting that they may be involved in insulin signal transduction. However, because the natural IGs are structurally hete...

The application of image-guided systems to sinus surgery is gaining in popularity. This study tried to evaluate the efficacy of image-guided surgery (IGS) in the fenestration of the sphenoid sinus in patients with chronic rhinosinusitis (CRS) who received revision functional endoscopic sinus surgery (FESS). A total of 51 CRS patients who received revision FESS incorporating IGS between January ...

The 45S ribosomal DNA (rDNA) units are separated by an intergenic spacer (IGS) containing the signals for transcription and processing of rRNAs. For the first time, we sequenced and analyzed the entire IGS region from three original species within the genus Saccharum, including S. spontaneum, S. robustum, and S. officinarum in this study. We have compared the IGS organization within three origi...

submitted to WPGM, 2006 The IGS precise orbits of GPS have been widely used in the world ever since the beginning of their broadcast in 1994. Major changes have taken place both in the data processing softwares and the reference frame over the years, but the orbits have not been updated. In this study we reanalyzed the GPS data from the IGS global tracking station since 1994 and compared our re...

We have analysed the role of tryptophan-derived secondary metabolites in disease resistance of Arabidopsis to the oomycete pathogen Phytophthora brassicae. Transcript analysis revealed that genes encoding enzymes involved in tryptophan, camalexin and indole glucosinolate (iGS) biosynthesis are coordinately induced in response to P. brassicae. However, a deficiency in either camalexin or iGS acc...
