Linkage mapping of quantitative trait loci requires analysis of a large number of animals. Although genetic markers isolated by representational difference analysis (RDA) and its modifications meet the needs, the number of these markers has been limited. In the present study, we established the arbitrarily primed (AP)–RDA method to isolate virtually an unlimited number of the high throughput ge...

OBJECTIVE This study reports on the energy, macro- and micronutrient intakes of a true longitudinal group of 143 urban black South African children from the Birth-to-Twenty (Bt20) study at two interceptions (2000 and 2003) when they were 10 and 13 years old, respectively. METHODS Subjects resided in the urban Johannesburg/Soweto area of the Gauteng Province in South Africa. Dietary intake was...

MANETs (Mobile ad hoc networks) are overloaded with their heavy usage choking traffic. Recent studies have been attempting to find feasibility of routes in these networks. Most proposed schemes failed consider the network traffic or MANET requirements. routing done by RPs (Routing Protocols) would perform better when they adhere QoS (Quality Service) application As a result, must satisfy numero...

Rapidly destructive arthritis (RDA) of the shoulder is a rare disease. Here, we report two cases, with different destruction patterns, which were most probably due to subchondral insufficiency fractures (SIFs). Case 1 involved a 77-year-old woman with right shoulder pain. Rapid destruction of both the humeral head and glenoid was seen within 1 month of the onset of shoulder pain. We diagnosed s...

Photoinduced electron transfer (PET) has been investigated in organized monolayers at the air-water interface and in monolayer assemblies on glass in an effort to evaluate the influence of solvent reorganization and molecular dynamics on PET. The donor monolayer contained an amphiphilic thiacyanine dye, and the electron acceptors were methyl viologen and dioctadecyl viologen, respectively. The ...

This study compared the traditional radiotracer method (Rt) for determination of dentifrice abrasivity to the recently introduced surface profile (Sp) method (ISO 11609). Specimens from human root dentin were prepared for each method and randomly assigned to 8 dentifrice/abrasive groups (n1⁄48), of wide abrasivity range. Aqueous dentifrice slurries or abrasive suspensions were used to brush spe...

cDNA representational difference analysis (cDNA-RDA) is a polymerase-chain-reaction-coupled subtractive and kinetic enrichment procedure for the isolation of differentially expressed genes. In this study, the technique was used to isolate novel genes specifically expressed in pancreatic cancer. cDNA-RDA was done on cDNA reverse transcribed from a poly(A)+ mRNA pool made from 10 cancer tissues (...
