OBJECTIVE Assess golimumab efficacy/safety through 5 years in patients with active ankylosing spondylitis (AS). METHODS 356 patients with AS were randomly assigned to placebo, golimumab 50 mg or 100 mg every 4 weeks. At week 16, patients with inadequate response early escaped with blinded dose adjustments (placebo to 50 mg, 50 mg to 100 mg). At week 24, all patients receiving placebo crossed ...
Background and Objectives: Serum amylase increases and its excretion fraction decreases in patients with renal failure. Excretion fraction can be used as a diagnostic way in individuals with acute renal transplant rejection. In this study, the association between amylase excretion fraction and acute renal transplant rejection, was investigated in pediatrics. Methods: in this case - control s...
Background: Cardiac resynchronization therapy (CRT) has proved as an efficient treatment in patients with end stage Heart failure. Previous studies showed the beneficial long term effects of CRT on the severity of mitral regurgitation (MR). The aim of this study was to evaluate acute effects of CRT on severity of MR. Methods: This study was a double blind randomized trial performed from 1387 t...
Pathogenic factors that may contribute to hypertriglyceridemia were studied in 55 patients who have been undergoing chronic hemodialysis treatment. Increased levels of triglyceride were observed in the patient group compared to normal controls (19o±93 mg/dL vs. 121±45 mg/dL, p<O.05). Similarly, augmented concentrations of VLDL-C were observed among patients compared to the control subjects...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
