Aims: To compare the values and acuracy of the test in anticyclic citrullinated peptides (Anti-CCP /ACPA) antibodies, Rheumatoid factor (RF), C-Reactive Protein (CRP) and disease activity index (PASI) in early diagnosis of untreated Psoriatic arthritis(PsA). Methods: Using the ELISA method of DIA-STATTM Anti CCP (Axis–Shield Diagnostics), sera of 70 participants were examined (35 untreated pati...

Thin-layer chromatography of α-amino acids has been performed on layers prepared from a 1:4 stannic arsenate–cellulose mixture. RF values of the amino acids were determined after development with a variety of mobile phases. Important synthetic ternary separations have been achieved on the basis of different RF values. Lysine and threonine have been selectively separated and quantitatively deter...

Missing values in a databases one of critical problem faced by the researchers in Data analysis and data mining. This work presents a suggested method for handling missing data values in data sets using Random Forest (RF) Technique. The use of RF present new principles to random splitting, it alters the tree growing process by narrowing its focus during split selection. For example, if the data...

Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of  non-homogeneity in RF receive and transmit. This can be the most effective source of error in  quantitative  studies  in  MRI  imaging.  Part  of  this  non-homogeneity  demonstrates  the  characteristics of RF coil and part of it is due to the interaction of RF field with the material being  imaged...

HPTLC analysis was carried out to determine the steroid compounds profile in the whole-plant samples of selected Polygonum species (P. chinense, P. glabrum and P. barbatum). The methanol extract of whole-plant samples obtained from Polygonum species (P. chinense, P. glabrum and P. barbatum) showed 6, 6 and 5 compounds, respectively, and were compared with stigmasterol and solasodine standards. ...

BACKGROUND RF(Rheumatoid factor) is usually thought to cause positive interference in immunoassay. Recently, our study showed that high-concentration RFs caused negative interference as well as positive interference in serum HBsAg(Hepatitis B surface antigen) ELISA(Enzyme-linked immunosorbent assay), but it is unclear that RF causing negative interference is an anomaly produced by a certain ELI...

Factors affecting the performance of 1 H heteronuclear decoupling sequences for magic-angle spinning (MAS) NMR spectroscopy of organic solids are explored, as observed by time constants for the decay of nuclear magnetisation under a spin-echo (T2' ). By using a common protocol over a wide range of experimental conditions, including very high magnetic fields and very high radio-frequency (RF) nu...

two dimensional thin layer chromatography on polyamide sheets is a useful method for identification of pth-amino acids which have very close rf-values. the solvent systems described here are particularly effective and have an edge over other solvent systems used for the separation of pth-amino acids. the solvent systems provide a clear separation of all pth-amono acids except lle / leu in a rel...

Developing countries have embarked on the promotion of “ICT access for all” through subsidized Information and Communication Technologies (ICTs), especially in underserviced areas of such countries. The main aim of the “ICT access for all” is to extend the communication services to the large areas of underserviced regions through subsidized communication services. In some instances, subsidies m...
