OBJECTIVE To compare the efficacy and safety of two different doses of celecoxib and diclofenac in the treatment of Norwegian patients with ankylosing spondylitis. METHODS In this 12-week, double-blind, non-inferiority trial patients were randomized to 200 mg once daily (qd) celecoxib, 400 mg qd celecoxib, or 50 mg three times daily (tid) diclofenac. The primary objective compared patients' a...

Established a three-dimensional model of treadmill, structural diagram of mechanical transmission, structural optimization model and kinematic analysis model, derived the values of connecting rods were 0.425 m, 1.673 m and 0.662 m by solving the optimization model, did kinematic analysis for treadmill using this set of parameters and kinematic simulation software Motion, Given the simulation cu...

In the present study, the effects of intrastriatal administration of different concentrations (40 microM, 400 microM, and 4 mM) of inorganic mercury (HgCl(2)) on the dopaminergic system of rat striatum were evaluated, using a microdialysis technique coupled to liquid chromatography-electrochemical detection. In previous studies, we discussed the effects of organic mercury (MeHg) administration ...

Hydroxyapatite (HA) is one of the most commonly used materials for the coating of bioceramic titanium (Ti) alloys. However, HA has poor mechanical properties and a low bonding strength. Accordingly, the present study replaces HA with a composite coating material consisting of fluorapatite (FA) and 20 wt % yttria (3 mol %) stabilized zirconia (ZrO₂, 3Y-TZP). The FA/ZrO₂ coatings are deposited on...

The 80-400 f/4.5-5.6G is a relatively large and bulky lens for the genre but overall, given its size I did not find it very heavy and found it to be well balanced even on a light D7100 without optional vertical grip. If this lens had the same metal construction as the 300 f/4 or 70-200 f/2.8 it would be even heavier. There is a lot of polycarbonate in the lens similar to the other recent f/4 ra...

As a sensitive and selective analytical technique, gold nanoparticles-based colorimetric sensing was characterized by its simplicity and cost-effectiveness. Specific methods have been extensively developed for different targets in diverse samples. In this study, a label-free method for sensing Co in aqueous solutions was described. The target was achieved by the induced aggregation of thiosulfa...

Consolidation of pure molybdenum through laser powder bed fusion and other additive manufacturing techniques is complicated by a high melting temperature, thermal conductivity ductile-to-brittle transition temperature. Nano-sized SiC particles (0.1 wt%) were homogeneously mixed with the printing characteristics, chemical composition, microstructure, mechanical properties compared to for scan sp...

In this paper, we perform unbiased structure searches combined with first-principles calculations to predict the stable structures and possible superconductivity of ErHn (n = 4~6) under pressures 50~300 GPa. Two novel compounds, ErH4 ErH6, are identified as thermodynamically dynamically above 50 GPa; ErH6 can stabilize in clathrate I4/mmm Im3¯m space groups, respectively. An analysis electronic...
