AIMS The effect of local anaesthetics on optic nerve function can be investigated by quantifying the relative afferent pupillary defect (RAPD). METHODS The study compared the depth of induced RAPD following posterior sub-Tenon's, retrobulbar, and peribulbar local anaesthetics using crossed polarising filters before cataract surgery (time 1 = 5 minutes), immediately after surgery (time 2 = 42 ...

Species-specific Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) markers were used to identify four species related to Anopheles (Nyssorhynchus) albitarsis Lynch-Arribàlzaga from 12 sites in Brazil and 4 in Venezuela. In a previous study (Wilkerson et al. 1995), which included sites in Paraguay and Argentina, these four species were designated "A", "B", "C" and "D". It was...

The random amplified polymorphic DNA (RAPD) technique has been used widely for purposes such as the construction of linkage maps, QTL analysis, evaluation of genetic diversity, and parentage tests. However, some minor bands of RAPD display a low reproducibility and low reliability. We describe a simple and efficient method for making minor RAPD bands clearer. The first step of this method is to...

Random amplified polymorphic DNA (RAPD) analysis was used to evaluate genetic diversity among 13 soil Penicillium strains originating from widely dispersed areas. Twenty one of the 34 synthetic random primers were found to identify polymorphism in amplification products. The results show a high level of diversity of RAPD markers among the strains. All the strains could be identified by their ch...

PCR-based DNA fingerprinting was used to characterize 48 clinical isolates of Yersinia enterocolitica. The samples were examined by random amplified polymorphic DNA (RAPD-PCR) and inter-repeat PCR (IR-PCR). IR-PCR with two enterobacterial repetitive intergenic consensus primers resulted in patterns which were poorly discriminated; 2 of 11 arbitrary primers (RAPD-PCR) provided sufficient discrim...

Wine quality is determined by the particular yeast strains prevailing at various stages of fermentation. Therefore, ability to make an easy, fast, and unambiguous discrimination yeasts strain level great importance. Here, tandem repeat-tRNA (TRtRNA) method with 5GAC or ISSR-MB primer sets random amplified polymorphic DNA (RAPD) analysis (GTG)3, R5, RF2 oligonucleotides were tested on non-Saccha...

Genetic relationships among 24 genotypes of Hyophila involuta collected from five different natural populations Mount Abu (Rajasthan) is analysed using RAPD and SSR markers. Based on efficiency parameters calculated for each marker system such as polymorphic information content (RAPD = 0.34; 0.66), index 2.78; 2.62) resolving power 8.13; 2.23), the shows higher values some indices but microsate...

ABSTRACT Collections of Puccinia triticina, the wheat leaf rust fungus, were obtained from Great Britain, Slovakia, Israel, Germany, Australia, Italy, Spain, Hungary, South Africa, Uruguay, New Zealand, Brazil, Pakistan, Nepal, and eastern and western Canada. All single-uredinial isolates derived from the collections were tested for virulence polymorphism on 22 Thatcher wheat lines that are nea...
