Background. This study compared the cyclic fatigue resistance, bending resistance and cross-sectional areas of Reciproc Blue (RPC Blue), WaveOne Gold (WOG), and Genius File (GF) NiTi rotary systems. Methods. Forty RPC Blue R25 (25/.08), 40 WOG Primary (25/.07) and 40 GF (25/.04) files were used in the present study. Flexibility of the files was determined by 45° bending test. The instruments we...
The levels of beta 2-microglobulin (beta 2-m) in serum and urine of 24 seropositive patients with rheumatoid arthritis (RA) treated with regular gold (sodium aurothiomalate) injections have been investigated. The values obtained were compared with levels from 20 seropositive patients with RA treated only with nonsteroidal anti-inflammatory drugs and 20 age and sex matched normal controls who ha...
For developing a free radical-quenched surface-enhanced Raman scattering (SERS) probe, starch, a linear molecule, was used as a protective layer to coat gold nanoshells (GNSs) as enhancement substrates and then, methylene blue (MB) was absorbed on the starch-coated GNSs as a free radical-responsive element. By detecting the change of the SERS intensity of MB on GNSs, the free radical-quenched S...
Serum soluble interleukin 2 receptor (sIL-2R) concentrations reflect lymphocyte activation in vivo. An investigation was carried out to determine if sIL-2R concentrations correlate with existing disease activity parameters in patients with rheumatoid arthritis (RA) and whether these concentrations are modulated by treatment with second line drugs. Seventy nine patients with rheumatoid arthritis...
Our objective was to evaluate methods for identifying cattle with high concentrations of Escherichia coli O157 in their feces. In two experiments, feces were collected from cattle orally inoculated with nalidixic acid (Nal)-resistant E. coli O157, and direct plating of diluted feces on sorbitol MacConkey agar with cefixime and potassium tellurite (CT-SMAC) containing Nal was considered the gold...
Objectives It was aimed to compare the cyclic fatigue resistances of ProTaper Universal (PTU), ProTaper Next (PTN), and ProTaper Gold (PTG) and the effects of sterilization by autoclave on the cyclic fatigue life of nickel-titanium (NiTi) instruments. Materials and Methods Eighty PTU, 80 PTN, and 80 PTG were included to the present study. Files were tested in a simulated canal. Each brand of ...
BACKGROUND Sodium aurothiomalate has been reported to have in vitro activity against Helicobacter pylori. Intramuscular gold, as given to patients with rheumatoid arthritis (RA), may therefore influence the colonisation of the gastric mucosa with H pylori. METHODS Two groups were compared. One group of 42 patients was treated with intramuscular gold; the other group of 58 patients was treated...
INTRODUCTION Both methotrexate (MTX) and gold sodium thiomalate (GSTM) have been shown to be very effective in the treatment of rheumatoid arthritis (RA) and to slow x-ray progression. The combination of both drugs could be useful because of their different and complimentary mechanisms of action. However, there is only one long-term study comparing this combination with MTX monotherapy. METHO...
OBJECTIVE To compare the efficacy of hydroxychloroquine, penicillamine, sodium aurothiomalate and auranofin in the treatment of active rheumatoid arthritis over a period of 5 yr. METHOD Five hundred and forty-one patients with definite or classical rheumatoid arthritis were entered into an open randomized controlled trial with a flexible dose regimen designed to reflect clinical practice. Dec...
Chondroitin sulfate proteoglycans (CSPGs) are glial scar-associated molecules considered axonal regeneration inhibitors and can be digested by chondroitinase ABC (ChABC) to promote axonal regeneration after spinal cord injury (SCI). We previously demonstrated that intrathecal delivery of low-dose ChABC (1 U) in the acute stage of SCI promoted axonal regrowth and functional recovery. In this stu...
