A multicenter, open-label, dose-escalation phase 1/2 study was undertaken to evaluate the optimal subcutaneous tocilizumab dose that would result in exposure comparable to the intravenous tocilizumab 8-mg/kg approved dose in patients with rheumatoid arthritis. A pharmacokinetic and biomarker approach was used to estimate the clinical optimal dose regimen of subcutaneous tocilizumab. Safety and ...

The Yersinia protein tyrosine phosphatase (PTPase) Yop51, a C235R point mutation (Yop51*), and a protein lacking the first 162 amino acids at the NH2 terminus (Yop51*delta 162) have been overexpressed in Escherichia coli and purified to homogeneity through the use of CM Sephadex C25 cation exchange chromatography followed by Sephadex G-100 gel filtration. Greater than 50 mg of homogeneous Yop51...

The cellular mechanisms of high dose systemic acetylcholine receptor (AChR) T cell epitope, alpha 146--162 peptide-induced tolerance in experimental myasthenia gravis were examined. CD4 cells are the prime target for alpha 146--162 peptide-induced tolerance. The expression of CD69, Fas, and B7.2 molecules on AChR-immune lymphocytes was enhanced within 4--12 h after tolerance induction. A high d...

We report on the characterization and target analysis of the small (s)RNA(162) in the methanoarchaeon Methanosarcina mazei. Using a combination of genetic approaches, transcriptome analysis and computational predictions, the bicistronic MM2441-MM2440 mRNA encoding the transcription factor MM2441 and a protein of unknown function was identified as a potential target of this sRNA, which due to pr...

AIMS To compare the culture and PCR methods for detection of Brucella melitensis in blood and lymphoid tissue samples obtained from slaughtered sheep (n = 162) testing positive/negative in serological tests (Rose Bengal test and serum agglutination test). METHODS AND RESULTS Of 162 sheep examined, 45 were positive and 117 negative in serological tests. A PCR assay based on a pair of Br. melit...

objective the aim of this study was to compare the sensitivity and specificity of acid fast and auramine-rhodamine staining and multiplex pcr for the detection of mycobacterium tuberculosiscomplex and non tuberculosis mycobacteria on formalin fixed paraffin embedded tissues (ffpe) materials and methods forty cases of ffpe pleural and bronchial tissue with chronic granulomatous inflammation and ...

Our analysis of 2707 news stories explores the framing of flooding in Britain over the past quarter century and the displacement of a once dominant understanding of flooding as an agricultural problem of land drainage by the contemporary concern for its urban impacts, particularly to homes and property. We document dramatic changes in the volume and variety of reporting about flooding since 200...
