[Biological markers of exposure to toxic agents].

Revue d'epidemiologie et de sante publique, 1986
Exposure to chemical agents may be assessed either qualitatively or semi-quantitatively with the help of a questionnaire (type of exposure and duration) or quantitatively either by the measurement of the concentration of the xenobiotics in the environment (ambient monitoring) or by the measurement of biological parameters related to the internal doses (

Nitrogen Containing Heterocycles as Anticancer Agents: An Overview.

Anti-Cancer Agents in Medicinal Chemistry, 2020
BACKGROUND Cancer is spreading all over the world and it is becoming leading cause of major deaths. Today's most difficult task for every researcher is to invent a new drug that can treat cancer with minimal side effects. Many factors including pollution,

BioBadge: a personal dosimetry technology for assessment of exposures to biological agents

SPIE Proceedings, 2003
The BioBadge is a biological dosimeter product based on a personal collection device developed by MesoSystems Technology. Designed to be worn by individuals in potentially biologically hazardous environments, the BioBadge allows for real-time collection, concentration, and analysis of biological agents present in the air.

[Biosafety in laboratories concerning exposure to biological agents].

Giornale italiano di medicina del lavoro ed ergonomia, 2007
Laboratory workers are exposed to a variety of potential occupational health hazards including those deriving from infectious materials and cultures, radiations, toxic and flammable chemicals, as well as mechanical and electrical hazard. Although all of them are significant, this paper will focus on biological hazards present in clinical and research ...

Handbook of Nuclear, Biological, and Chemical Agent Exposures

2007
Treating nuclear, biological, and chemical agent exposures presents a unique set of challenges. These scenarios usually involve multiple exposures, sometimes even mass exposures, from a single, often poorly-defined, event. Early symptoms are not distinct and can often be variable.

History of the biological factor and its place in forensic medicine

Issues of establishing the severity of harm caused to human health as a result of exposure to a biological factor
The article presents historical aspects on the development of ideas about infectious agents and methods of transmission of infectious diseases. It is shown that in forensic medicine the issues of the biological factor remain poorly studied.

Exposure to chemicals, physical agents, and biologic agents in mycosis fungoides and the Sézary syndrome.

Cancer treatment reports, 1979
The history of occupational, environmental, and/or iatrogenic exposure to potential carcinogenic agents was obtained at the time of onset of skin disease in 43 of 44 patients with cutaneous T-cell lymphoma (mycosis fungoides and the Sézary syndrome) entering a National Cancer Institute therapeutic trial.

Urinary excretion of mercapturates as a biological indicator of exposure to electrophilic agents.

Journal of hygiene, epidemiology, microbiology, and immunology, 1984
The urinary excretion of mercapturates was followed photometrically in individuals exposed to styrene, a mixture of aromatic hydrocarbons, butadiene, vinyl chloride, 1,1,1-trichloroethane, trichloroethylene, tetrachloroethylene, 1,1,1-trifluoro-2-bromo-2-chloroethane (Halothane), ethylene oxide, epichlorhydrin, bis(chloromethyl)-ether, N ...

Risk Assessment of laboratory technicians' exposure to biological and chemical agents

2019
Risk prevention must be based on a correct and permanent risk assessment in the work as a core activity of health and safety services. In several activities workers are not aware of the risks they are exposed to, namely when it is not their common work.
