OBJECTIVES This study aimed to evaluate the relationship between the 25-hydroxyvitamin D [25(OH)D] level and rheumatoid arthritis (RA) and the correlation between serum vitamin D level and RA activity. METHODS We searched the PUBMED, EMBASE, and Cochrane databases and performed a meta-analysis examining the vitamin D level and prevalence of vitamin D deficiency in patients with RA compared to...

background: rheumatoid arthritis (ra) is a chronic inflammatory disease with many genetic factors predisposing to disease susceptibility. the aim of the present study was to investigate the impact of cd226 rs727088 and rs763361 polymorphisms and susceptibility to ra in a sample of the iranian population. methods: this case-control study was carried out on 100 patients with ra and 104 healthy su...

This is the second part of a two-part paper on the application of computer-aided diagnosis to diffuse optical tomography (DOT) for diagnosing rheumatoid arthritis (RA). A comprehensive analysis of techniques for the classification of DOT images of proximal interphalangeal joints of subjects with and without RA is presented. A method for extracting heuristic features from DOT images was presente...

regarding the infl uence of anti-cyclic citrullinated peptide (CCP) on anticentromere antibody (ACA)-positive patients suff er ing from rheumatoid arthritis (RA) [1]. Th eir fi ndings explore the eff ect of ACA positivity in a patient group diff erent from the cohort of primary Sjögren syndrome (SS) patients we chose to study [2]. Due to the diff erent study population and the retrospective nat...

OBJECTIVE Autoantibodies have been demonstrated in single serum samples from healthy subjects up to 10 years before they developed rheumatoid arthritis (RA). However, the time course for the development of antibodies before onset of clinical RA is unknown, nor is it known which antibody, or combinations of antibodies, might be most sensitive or specific for predicting future development of the ...

The cations and anions of the chiral title compound, C(5)H(14)N(2) (2+)·2Cl(-)·0.42H(2)O, are linked by N-H⋯Cl hydrogen bonds into chains propagating in [100], which contain R(4) (2)(14) loops.

BACKGROUND As long-term treatment with antitumour necrosis factor (TNF) drugs becomes accepted practice, the risk assessment requires an understanding of anti-TNF long-term safety. Registry safety data in rheumatoid arthritis (RA) are available, but these patients may not be monitored as closely as patients in a clinical trial. Cross-indication safety reviews of available anti-TNF agents are li...

the basic models of data envelopment analysis (dea) are designed in such a way that the values of input and output indicators should be identified and known in them. in other words, these models are not used to consider inaccurate, interval, fuzzy, judgment data. in this paper, the aim is to not only review the past researches about the efficiency of the units by interval data and represent the...

australian grapevine viroid (agvd), an apscaviroid of the family pospiviroidae, was recently identified in vineyards of southern iran. it had a relatively wide host range and caused stunting, leaf deformation, mottling and vein clearing in experimental hosts upon mechanical inoculation of nucleic acid extracts or agroinfiltration of the viroid infectious cloned dna. predicted secondary structur...
