AIMS To develop a job-exposure matrix (JEM) from personal and static respirable crystalline silica (RCS) measurements in UK industrial silica sand workers. METHODS A total of 2429 personal and 583 static RCS dust samples were collected using cyclone samplers at seven UK quarries between 1978 and 2000. These data were combined, and analysis of variance using general linear models was used to e...
Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension characterised by predominant remodelling of pulmonary venules. Bi-allelic mutations in the eukaryotic translation initiation factor 2α kinase 4 (EIF2AK4) gene were recently described as the major cause of heritable PVOD, but risk factors associated with PVOD remain poorly understood. Occupational exposures have bee...
Magnetic nanostructures that are magnetized perpendicular to their surface are central to many developing technologies, including spintronics devices and patterned media, because of the requirement to maintain thermal stability as device dimensions are scaled further into the nanoscale. Multilayer or superlattice materials such as Co(Fe)/Pd are convenient for these applications due to their hig...
To critically evaluate the association between diesel exhaust (DE) exposure and the risk of lung cancer, we conducted a systematic review of published epidemiological evidences. To comprehensively identify original studies on the association between DE exposure and the risk of lung cancer, literature searches were performed in literature databases for the period between 1970 and 2013, including...
JEM © The Rockefeller University Press $8.00 Vol. 203, No. 1, January 23, 2006 27–33 www.jem.org/cgi/doi/10.1084/jem.20051787 27 Graft versus host disease (GVHD) is an immune reaction of donor lymphoid cells to antigens expressed by recipients of hematopoietic stem cell transplantation (HSCT). In the acute form, occurring within 100 d after transplant, GVHD is a signifi cant cause of transplant...
Lorentz TEM enables to map quantitatively magnetic induction fields in the sample. A specifically designed objective lens, a coherent electron source, and a biprism filament can achieve magnetic imaging at the nanometer scale through off-axis electron holography experiments. However, this equipment is specialized and therefore not suited to many microscopy labs. In this article, we describe an ...
The changes reflect our ongoing determination to offer the speediest publication times and the most accurate figure reproduction. No more paper please Our new instructions to authors are geared entirely toward online submission. Beyond saving trees, this switch to accepting only electronic manuscripts means faster processing of papers from submission to review to publication. Currently, most re...
