Gene expression profiles in asbestos-exposed epithelial and mesothelial lung cell lines
…The authors noted that cell experiments cannot precisely reflect conditions in the body, and that many changes probably reflect general responses to toxic substances. The authors concluded that the study identified several targets for further investigation…

The in vitro activities of a highly carcinogenic mineral fibre--potassium octatitanate
…with present techniques, genotoxicity tests cannot rank mineral fibres by carcinogenicity, and that general cytotoxic activity remains the best predictor. They noted that the weak, poorly dose-related transformation response may indicate activity near the assay…

Microwave polymerisation of epoxy resin: rapid processing technique in ultrastructural pathology
…than 2mm across polymerised slightly unevenly. A lymphoma sample given both microwave fixation and polymerisation was of very acceptable quality. The authors concluded that microwave polymerisation is practicable, although its general usefulness remained to be established.

The social context of occupational disease: asbestos and South Africa
General issues of industrial health are raised in relation to the production of asbestos and asbestos-related diseases in South Africa., A historical analysis of these diseases and their control in Britain demonstrates some general problems…

The relationship between respiratory impairment and asbestos-related pleural abnormality in an active work force
With the general improvement in environmental controls in workplaces where asbestos is used, an increasing number of workers are seen who exhibit isolated pleural plaques. The question as to whether these are associated with respiratory impairment…

Environmental asbestos pollution -- situation in Poland
Environmental exposure of the general population to asbestos in Poland is mainly due to degradation of very popular asbestos-cement products and the resultant release of the elementary asbestos fibres into the ambient air. Assessments of…

Mortality among United Kingdom servicemen who served abroad in the 1950s and 1960s
The Registrar General's decennial supplements on occupational mortality provide only limited information on mortality in the armed forces in the United Kingdom. Mortality has therefore been studied among a group of 30,619 United Kingdom…

UK Naval Dockyards asbestosis study: survey of the sample population aged 50-59 years
As part of a general morbidity study of all civilian employees in the four Royal Naval Dockyards, the clinical, radiological and physiological effects of exposure to asbestos in 1200 men aged 50-59 years were studied…

Occupational life course and lung cancer risk in men. Findings from a socio-epidemiological analysis of job-changing histories in a case-control study
Psychosocial factors in general, and the social and psychological conditions of work and occupation in particular, have attracted little attention to the epidemiological investigation into the occupational-related causes of lung cancer. There is some evidence…

Pleural abnormalities in the Framingham Heart Study: prevalence and CT image features
The prevalence of pleural abnormalities in the general population is an epidemiologically important index of asbestos exposure, which has not been investigated since a radiography-based study in 1980. We examined 2633 chest CT scans (mean…

Pleural malignant mesothelioma in Tuscany, Italy (1970-1988): I. Anatomo-pathologic aspects
Our investigation did not confirm the general experience that significant numbers of cases initially considered malignant mesothelioma or metastatic carcinoma are actually found to be metastatic carcinoma or malignant mesothelioma, respectively, upon deeper investigation using ancillary…

Use of death certificates in epidemiological studies, including occupational hazards: variations in discordance of different asbestos-associated diseases on best evidence ascertainment
There is extensive information on discordance in general between accuracy of medical diagnoses on death certificate categorization of cause of death and available clinical and histopathological data. This is as true for occupational disease as for…

Extrapolation from occupational studies: a substitute for environmental epidemiology
Extrapolation from occupational data to general environmental exposures gives some interesting results, and these results might be useful in our decision-making process. These results could never be observed by environmental epidemiology and this method probably…

Asbestos and other ferruginous bodies: their formation and clinical significance
…with asbestos. At the highest levels of exposure, numbers of asbestos bodies correlate in a general way with the presence of asbestosis, although no precise value has been determined above which asbestosis is always found. In…

Quantitative Assessment of Asbestos Fibers in Normal and Pathological Pleural Tissue-A Scoping Review
pleural mesothelioma is a rare cancer in the general population, but it is more common in subjects occupationally exposed to asbestos. Studies with asbestos fiber quantification in pleural tissue are scarce: for this reason, we aimed…

Dextrose-Containing Carrier Solution for Hyperthermic Intraperitoneal Chemotherapy: Increased Intraoperative Hyperglycemia and Postoperative Complications
Intraoperative hyperglycemia is associated with infectious complications in general surgery patients. This study aimed to determine if the use of lactated Ringer's (LR) carrier solution during hyperthermic intraperitoneal chemotherapy (HIPEC) would lower the incidence of…

Comparative carcinogenicity study of a thick, straight-type and a thin, tangled-type multi-walled carbon nanotube administered by intra-tracheal instillation in the rat
Multi-walled carbon nanotubes can be divided into two general subtypes: tangled and straight. MWCNT-N (60 nm in diameter) and MWCNT-7 (80-90 nm in diameter) are straight-type MWCNTs, and similarly to asbestos…

Developing Asbestos Job Exposure Matrix Using Occupation and Industry Specific Exposure Data (1984-2008) in Republic of Korea
The goal of this study is to develop a general population job-exposure matrix (GPJEM) on asbestos to estimate occupational asbestos exposure levels in the Republic of Korea. Three Korean domestic quantitative exposure datasets collected from…
