In Britain, 14 carcinogenic agents and occupational circumstances currently account for 86% of estimated occupation attributable cancer. The future burden associated with these carcinogens has been forecast, using attributable fractions for forecast scenarios representing patterns of past and predicted future exposure, and exposure levels representing the introduction of new occupational exposu...

Dental plaque is a bacterial biofilm structure, neatly organized and attached to the tooth surface, which contains inorganic components such as calcium phosphorus derived from saliva. Bacteria in that stick surface of teeth will provide place for new bacteria grow. Disclosing solution coloring agent works change color dental contrast with white surface. Erythrosine red commonly used disclosing ...

Cancer is considered as major leading cause for death in India and around world. Modern drug-targeted therapies have undoubtedly improved treatment to the cancer patients but also evoke severe side effects. Organ failure and immunosuppression is also a reason for death of cancer patients. However, advanced metastasized stage of cancers remained untreatable at present. So, there is need for the ...

Even though epidemiological studies have identified arsenic compounds as carcinogenic to humans, they are not mutagenic in bacterial and mammalian test systems. However, they increase the mutagenicity and clastogenicity in combination with other DNA damaging agents and there are indications of inhibition of DNA repair processes. We investigated the effect of arsenic(III) on nucleotide excision ...

The carcinogenic process in the liver was monitored from early nonneoplastic changes to the development of tumors in two well-known models; IP administration of dimethylnitrosamine (DMN) to newborn mice, and feeding of rats with acetylaminofluorene (AAF). Liver parenchyma cells and liver tumor cells were isolated by collagenase treatment and prepared for flow cytometric (FCM) measurements of nu...

BACKGROUND Previous studies tried to assess the association between socioeconomic status and laryngeal cancer. Alcohol and tobacco consumption explain already a large part of the social inequalities. Occupational exposures might explain a part of the remaining but the components and pathways of the socioeconomic contribution have yet to be fully disentangled. The aim of this study was to evalua...

This fifty-ninth volume of IARC Monographs on the Evaluation of Carcinogenic Risks ta Humans contains monographs on three human hepatotropic viruseshepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HD~ also known as the delta agent). Until now, the subjects of IARC Monographs have been mainly single chemical compounds and, to a lesser extent, groups of chemicals, complex m...

Melatonin is a hormone that exhibits many bioactivities such as antioxidant, anti-inflammatory, anti-carcinogenic, anti-diabetic, neuroprotective, and anti-aging activity. In addition, melatonin has been used to strengthen the effect of drugs or agents for treatment in different disease models cancer, tumor, bacterial infection, autoimmune diseases, gastrointestinal diseases. According recent s...

The textile manufacturing industry consists of a wide range of occupations including spinning, weaving, knitting, dyeing and finishing of natural and synthetic fibres to produce fabrics, yarns and carpets. The range of exposures in the industry includes textile related dusts, chemicals used in making synthetic textiles, sizing agents, oil mist, dyes, solvents, crease-resistance agents, flame re...

This article is a discussion of occupational cancer in Italy. The introduction provides the necessary context of Italian industrialization and occupational health regulation. This is followed by a review of Italian epidemiologic studies of occupational cancer risks considered in terms of relative measures of risk and attributable risk of carcinogenic agents or exposure circumstances. We attempt...
