Beryllium

01/01/2003 - "Brush Wellman, the world's leading producer and supplier of beryllium products, has systematically hidden cases of beryllium disease that occurred below the threshold limit value (TLV) and lied about the efficacy of the TLV in published papers, lectures, reports to government agencies, and instructional materials prepared for customers and workers. "
03/01/2001 - "Efficacy of serial medical surveillance for chronic beryllium disease in a beryllium machining plant."
07/01/2007 - "The aims of this study were to determine the relationship between CD57 expression, a marker of T-cell senescence, and severity of chronic beryllium disease (CBD) and to determine the phenotypic and functional characteristics that differentiate beryllium-specific CD4(+) T cells in lung and blood. "
04/01/2005 - "The goal of this study was to characterize activation pathways of beryllium-responsive bronchoalveolar lavage (BAL) CD4(+) T cells from chronic beryllium disease patients to identify possible therapeutic interventional strategies. "
10/01/2004 - "We recommend that the results of this study be used to target at-risk audiences for hazard communications intended to prevent beryllium sensitization and chronic beryllium disease."

06/01/1951 - "Spontaneous remission of chronic beryllium poisoning from fluorescent lamp manufacturing; report of a case."
06/01/2012 - "Study the effect of beryllium reflector poisoning on the Syrian MNSR."
11/30/1965 - "[Experimental animal studies on beryllium poisoning]."
07/01/1951 - "Studies on the mechanism of acute beryllium poisoning."
06/01/2012 - "This paper illustrates the impact of poisoning accumulation in the beryllium reflectors on reactivity for the Syrian MNSR research reactor. "

02/01/2006 - "For arc furnace particles, k (1.6 +/- 0.6 x 10(-7)) was significantly greater than observed for the BeO materials (p < 0.00001), despite the fact that the chemical form of beryllium in the aerosol was BeO. "
02/01/2006 - "To better understand the dissolution of beryllium materials associated with elevated prevalence of sensitization and CBD, single-constituent (beryllium oxide (BeO) particles sampled from a screener operation, finished product BeO powder, finish product beryllium metal powder) and multi-constituent (particles sampled from an arc furnace during processing of copper-beryllium alloy) aerosol materials were studied. "

11/01/2014 - "This study confirmed the lack of an increase in mortality from lung cancer and nonmalignant respiratory diseases related to insoluble beryllium compounds. "
11/01/2014 - "This study investigated lung cancer and other diseases related to insoluble beryllium compounds. "
05/01/2011 - "This study provides evidence that lung cancer risk is elevated at levels near the current US Occupational Safety and Health Administration beryllium exposure limit of 2.0 μg/m(3) DWA for workers."
04/01/2009 - "Exposure to beryllium and occurrence of lung cancer: findings from a cox proportional hazards analysis of data from a retrospective cohort mortality study."
01/01/2007 - "Occupational medicine practitioners may want to integrate findings from this study into advice they give beryllium-exposed workers concerned about lung cancer."

10/01/1970 - "In vitro studies on granulomatous hypersensitivity to beryllium."
11/01/1965 - "[Study of the ability of beryllium compounds to produce delayed type allergy]."
10/01/1951 - "Cutaneous hypersensitivity due to beryllium; a study of thirteen cases."
04/01/2012 - "It has been used in beryllium-health effects, and its role is expanding in metal allergy. "
08/01/2009 - "Contrary to common understanding, these cases suggest that ABD and CBD represent a continuum of disease, and both involve hypersensitivity reactions to beryllium. "
