This analysis documents the process and results of reliability determination of the PhotoMultiplier Tube (PMT) components of the JEM-EUSO telescope under the different radiation sources, UV radiation, Total Ionizing Doses (TIDs), and Single Event Transients. In terms of UV Ionization, the transmittance of the glass of the PMTs during the 5-year duration of the mission is greater than 99.98%, th...
MATERIALS AND METHODS Stock cultures of T. aceti were grown axenically at 27 °C in a liquid medium described by Castillo and Krusberg (2) . Female nematodes from two cultures were examined, one of which had been maintained at East Wareham for 4 yr and the other obtained from the Department of Cell Physiology, Boston Biomedical Research Institute . Age at sacrifice for electron microscopy was de...

In MS lesions, perivascular activation of microglia ...
We investigated the association between occupational exposure to extremely low-frequency magnetic fields (MFs) and the risk of glioma and meningioma. Occupational exposure to MF was assessed for 489 glioma cases, 197 meningioma cases, and 799 controls enrolled in a hospital-based case-control study. Lifetime occupational history questionnaires were administered to all subjects; for 24% of jobs,...

Indeed, increasing evidence suggests that qualitative rather than quan...
JEM © The Rockefeller University Press $8.00 Vol. 203, No. 1, January 23, 2006 15–20 www.jem.org/cgi/doi/10.1084/jem.20051753 15 Innate immune cell activation via Toll-like receptors induces the release of infl ammatory cytokines, chemokines, and mediators. A rapid and robust response of macrophages and dendritic cells is needed for the control and elimination of fast-growing microbial invaders...
