Biologic response to environmental toxins

The American Journal of Forensic Medicine and Pathology, 1983
Biological response to environmental toxins results from the sum of natural, environmental, avocational, inapparent, and occupational exposures. These external exposures result in acceptable or unacceptable levels of absorption or internal exposure based on anticipated biological effects.

Verification of Biological and Toxin Weapons Disarmament

Science & Global Security, 1991
This chapter summarizes the characteristics of biological and toxin weapons; the nature, capabilities, and limitations of protective measures; and the existing provisions and agreements for confidence-building and international verification of compliance with the Biological Weapons Convention (BWC).

Chemistry and Biological Activity of AAL Toxins

1996
AAL toxins and fumonisins comprise a family of highly reactive, chemically related mycotoxins that disrupt cellular homeostasis in both plant and animal tissues. Two critical issues to resolve are the detection of the entire family in food matricies and the mode of cellular disruption.

Therapy and prophylaxis of inhaled biological toxins

Journal of Applied Toxicology, 2003
AbstractThis review highlights the current lack of therapeutic and prophylactic treatments for use against inhaled biological toxins, especially those considered as potential biological warfare (BW) or terrorist threats. Although vaccine development remains a priority, the use of rapidly deployable adjunctive therapeutic or prophylactic drugs could be ...

Biological properties of staphylococcal α-toxin

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1974
Abstract The biological properties of staphylococcal α-toxin were examined. 1. 1. We have confirmed that α-toxin, at a concentration of 1 μg/ml, induced spastic paralysis of isolated mammalian smooth muscle, which was not released by isoproteranol and was not responsive to added Ca2+ or K+. 2. 2.

Trends in Biological Degradation of Cyanobacteria and Toxins

2011
Cyanobacteria are known as blue-green algae, blue-green bacteria, and Cyanophyta. They are present in both toxic and non-toxic forms and it is actually the toxic form which proliferates in the aquatic environment. There are principally two types of toxins (neurotoxin and hepatotoxin) which lead to adverse environmental and human health impacts.

Aerosolized biologic toxins as agents of warfare and terrorism

Respiratory Care Clinics, 2004
Incomplete participation in the 1972 Biological Weapons Convention treaty and noncompliance by several signatory nations makes the malicious use of aerosolized biologic toxins a continuing threat. Unfortunately,prompt diagnosis of toxin exposure may be confounded by a paucity of pathognomonic features and limited diagnostics, but the scenario of ...

Detection of Biological Toxins on an Active Electronic Microchip

Analytical Biochemistry, 2001
An electric-field-driven assay for fluorescein-labeled staphylococcal enterotoxin B and cholera toxin B was developed on an active electronic microchip. An array of microlocations was transformed into an immunoassay array by electronically biasing electrodes at each microlocation to attract biotinylated capture antibodies.

The Biological Disposition of Drugs and Inorganic Toxins

2009
This chapter is a discussion of how some foreign substances get into the body, how they become distributed, what their effects are, and how they are eliminated from the body. Lead is the exemplar in the biological discussion, but the biological concepts can be applied to many other substances.
