There have been few systematic studies of the non-malignant health effects of alpha-particle radiation in humans. Animal studies and a report on plutonium-exposed workers from Russia suggest an association between high doses to the lung from plutonium exposure and the development of fibrotic lung disease. Prompted by a case of lung fibrosis in a retired plutonium worker, we tested the hypothesi...

Traditional film-screen radiography (FSR) has been useful in the recognition and evaluation of interstitial lung diseases, but is becoming increasingly obsolete. To evaluate the applicability of storage phosphor digital computed radiography (CR) images in the recognition of small lung opacities, we compared image quality and the profusion of small opacities between FSR and CR radiographs. We sc...

Over the past 20 years, practice guidelines have become an increasingly popular tool for synthesis of clinical information. Clinical practice guidelines are commonly defined as systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. The objectives of guidelines are to enhance appropriateness of practice,...

OBJECTIVE Fas/APO-1 (CD95) and Fas Ligand (FasL) is a major mediator system that activates programmed cell death (apoptosis) and is most important for pulmonary cellular homeostasis. Another form of Fas, circulating soluble Fas (sCD95), produced by alternative mRNA splicing antagonizes the cell-surface Fas function. It was the aim of the study to test the hypothesis that the Fas/FasL system is ...

OBJECTIVES Pneumoconiosis in China remains a disease with substantial public health significance. Diagnostic standards for the pneumoconioses are based on traditional film-screen radiography (FSR). However, FSR is increasingly being replaced with digital radiographic imaging, which has become the predominant technology available in Chinese clinical practice. To evaluate the applicability of dig...

BACKGROUND Construction workers are exposed to quartz containing respirable dust, at levels that may cause fibrosis in the lungs. Studies so far have not established a dose-response relation for radiographic abnormalities for this occupational group. AIMS To measure the extent of radiographic abnormalities among construction workers primarily exposed to quartz containing respirable dust. ME...

I propound a few heresies, and indulge in some dubious speculations. 1 Process Calculi as Generic Theories What counts as a successful theory in Computer Science? Consider obvious exemplars such as • Process Calculi • Type Systems • Model-checking It is not the case that there is a single agreed model, notation, formalism, tool or language in any of the above areas. In fact there are a profusio...

BACKGROUND In Idiopathic pulmonary fibrosis (IPF) irreversibly progressive fibrosing parenchymal damage, leads to defects in mechanics and gas exchange, manifesting with disabling exertional dyspnea. Previous studies have shown a relationship between fibroblast foci (FF) profusion and severity and survival and a relationship between dyspnea grade and severity and outcome. We hypothesized a rela...
