OBJECTIVES To investigate the clinical impact of 1-year certolizumab pegol (CZP) therapy added to the first year of 2-year methotrexate (MTX) therapy, compared with 2-year therapy with MTX alone. METHODS MTX-naïve patients with early rheumatoid arthritis (RA) with poor prognostic factors were eligible to enter Certolizumab-Optimal Prevention of joint damage for Early RA (C-OPERA), a multicent...
STUDY OBJECTIVES Evaluate the hypnotic efficacy of gaboxadol, a selective extrasynaptic GABAA agonist (SEGA), in a phase advance model of transient insomnia. DESIGN A randomized, double-blind, cross-over study in which habitual sleep time was advanced by 4 h. SETTING Sleep research laboratories. PARTICIPANTS 109 healthy subjects (18-58 y). INTERVENTIONS Gaboxadol 5 mg, 10 mg, and 15 mg ...
Methods Plasma concentrations were modeled for patients treated with CAN (n = 50) or PBO after CAN treatment (n = 50) and used to predict flare risk by a validated and qualified simulation of the CAN exposure-flare hazard relationship. The model considered both PBO and CAN treatments and multiple covariates, including baseline steroid dose, heterogeneity of the population with respect to diseas...
BACKGROUND Insecticide resistance is one of the serious problems for German cockroach control program. This study was conducted to determine the bendiocarb and Carbaryl resistance mechanisms in German cockroaches using the piperonyl butoxide (PBO). METHODS Bioassay tests were conducted with 4 to 6 different concentrations of both insecticides with four replicates of 10 susceptible strain cock...
Barium hexaferrite powder samples with grains in the μm-range were obtained from solid-state sintering, and crystals with sizes up to 5 mm grown from PbO, Na₂CO₃, and BaB₂O₄ fluxes, respectively. Carbonate and borate fluxes provide the largest and structurally best crystals at significantly lower growth temperatures of 1533 K compared to flux-free synthesis (1623 K). The maximum synthesis tempe...
TheSanRomanstrainof the southern cattle tick,Boophilusmicroplus, collected fromMexicowaspreviously reported to have a high level of resistance to the organophosphate acaricide coumaphos. An oxidative detoxification mechanism was suspected to contribute to coumaphos resistance in this tick strain, as coumaphos bioassay with piperonyl butoxide (PBO) on larvae of this resistant strain resulted in ...
واهلشگرهای(relaxor) پایه سرب در فناوری و ساخت خازنهای چند لایه ای و قطعات الکترواپتیکی مواد مهمی به شمار می آیند. یکی از مهمترین این ترکیبات سیستم (pb(mg1/3nb2/3)o3)pmn است که ثابت دی الکتریک بسیار بالایی دارد. در این پروژه تشکیل فاز pmn بوسیله روشهای کلومبایت و تارتارات بررسی شد. پودر کلومبایت (mgnb2o6) با کلسینه مخلوط mgo (با استفاده از 3% وزنی mgo اضافی) و nb2o5 در 1200 درجه سانتیگراد سنتز...
Linear Pseudo-Boolean constraints offer a much more compact formalism to express significant boolean problems in several areas, ranging from Artificial Intelligence to Electronic Design Automation. This paper proposes a new algorithm for the Pseudo-Boolean Optimization Problem (PBO) which integrates features from recent advances in Boolean Satisfiability (SAT) and classical branch and bound alg...
A new method for determination of pyrethroids, pyrethrins, and piperonyl butoxide (PBO) by high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS) was developed for aquatic sediments. The method detection limits for pyrethroids (15 compounds), pyrethrins, and PBO ranged from 0.16 to 1.50 ng/g sediment, which was suitable for detecting these chemicals at environmentally ...
