Chlamydia pneumoniae has proved to be difficult to isolate and propagate in cell culture. We compared the growth of three strains of C. pneumoniae, TW-183 and two clinical isolates from Brooklyn, N.Y., in five cell lines, including HeLa 229, McCoy, HL, HEp-2, and HTED, an immortalized human tracheal cell line. HEp-2 was the most sensitive cell line tested. When 10-fold dilutions of three C. pne...
BACKGROUND Herpes Simplex Virus (HSV) keratitis is a leading cause of corneal blindness. Definitive laboratory diagnosis is essential for timely management. Collection of corneal scrapings in patients with advanced epithelial keratitis and corneal thinning poses perforation risks; tear fluid is a feasible and convenient alternative but has not been widely evaluated for HSV detection. METHODS ...
INTRODUCTION There is increasing evidence to suggest that bone marrow lesions (BMLs) play a key role in the pathogenesis of osteoarthritis (OA). However, there is a lack of long term data. The aim of this study was to describe the natural history of knee BMLs, their association with knee pain and examine predictors of BML change over eight years. METHODS A total of 198 subjects (109 adult off...
Aim: Abnormal expression patterns of beta-tubulin isotypes may provide a molecular rationale for the behaviour of lymphoma subtypes. In the present study class II and III beta-tubulin expression was assessed in non-neoplastic and neoplastic lymphoid tissues with reference to potential utility as new tumour biomarkers. Methods and results: In this cross-sectional study class II and III beta-tubu...
BACKGROUND Bevacizumab and erlotinib have been demonstrated to prolong overall survival in patients with non-squamous non-small cell lung cancer (NSCLC). We designed a four-arm Phase III trial to evaluate the efficacy and toxicity of the combination of docetaxel, carboplatin, bevacizumab, and erlotinib in the first-line treatment of patients with NSCLC. METHODS A total of 229 patients with st...
