The incidence of pseudotumor formation has been reported to be 1% in patients with metal-on-metal resurfacing arthroplasties. This complication is not exclusive to these patients. We report a case of pseudotumor formation secondary to femoral head-neck corrosion after a metal-on-polyethylene uncemented total hip arthroplasty.
Isolation of nuclei is widely used in analyses such as DNA footprinting, gel retardation and runon transcription assays. When we applied the NP-40 lysis method of Nevins (1) to progenitors of the monocytic lineage, we found that these cells have a very fragile nuclear membrane which is easily susceptible to partial premature lysis. Therefore, we developed a(More)
INTRODUCTION We investigated whether a group of pathologists could reproducibly apply the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) classification for lung adenocarcinoma to a cohort of stage 1 tumors and whether this architectural classification and/or other parameters(More)
In order to investigate the molecular basis for the regulated expression of plasminogen activator inhibitor type 2 (PAI-2), we sought to identify monocyte-derived nuclear factors which interact with the PAI-2 gene. We have explored the application of Southwestern blot mapping as an approach for identifying specific DNA-protein interactions and targeting(More)
BACKGROUND Patients with metastatic breast cancer often have pulmonary symptoms with varying aetiologies. Transtuzumab is an extremely important drug used in the treatment of Her 2 neu over-expressing breast cancers. In this report we describe a case of organizing pneumonia associated with use of transtuzumab in metastatic breast cancer. Only three such(More)
Purpose: Reliable and reproducible methods for identifying PD-L1 expression on tumor cells are necessary to identify responders to anti-PD-1 therapy. We tested the reproducibility of the assessment of PD-L1 expression in non-small cell lung cancer (NSCLC) tissue samples by pathologists.Experimental Design: NSCLC samples were stained with PD-L1 22C3 pharmDx(More)
