Toxins: Bacterial and Marine Toxins
Clinics in Laboratory Medicine, 2006The term toxin refers in a specific way to a toxic substance of biologic origin; that is, a true toxin is a poison produced by a living organism. The purpose of this article is to review some of the most potentially dangerous toxins of concern today. Mechanisms of action, routes of exposure, diagnostic tools, and treatment recommendations are addressed.

Anesthesiology Clinics of North America, 2006
Exposures to toxins are prevalent, frequently complicate surgical emergencies, and impact critical care. A fundamental understanding of pathophysiologic principles and management strategies is essential for the anesthesiologist frequently responsible for the acute care of patients who have toxicologic exposures. Given their pervasiveness and ability to

Toxicon, 2011
Muscarinic toxins isolated from the venom of Dendroaspis snakes may interact with a high affinity, large selectivity and various functional properties with muscarinic receptors. Therefore, these toxins are invaluable tools for studying the physiological role, molecular functioning and structural organization of the five subtypes of these G-Protein ...

Trends in Microbiology, 2001
Researchers from Harvard Medical School have identified mutants of the anthrax toxin that could be used in the development of a therapeutic vaccine, as reported in Science. Rats injected with mutant protective antigen and a normally lethal dose of the anthrax toxin survived, suggesting that the mutant antigen could be useful as both a vaccine and an ...

Hormone, lectin and toxin-toxin conjugates
1988In order to better understand the relative importance of the A and B chains of diphtheria toxin and ricin, chimeras or hybrid toxins have been constructed with diphtheria toxin subunits and ricin subunits coupled to a number of different binding moieties.

Toxins and Their Phytoremediation
2010The agricultural and industrial revolutions in the last few decades have resulted in increased concentration of toxins in our environment that are now-a-days a major cause of toxicity in plants and animals. Among different toxins, increasing levels of salts, heavy metal, pesticides and other chemicals are posing a threat to agricultural as well as ...

AbstractBlue‐green algae are found in lakes, ponds, rivers and brackish waters throughout the world. In case of excessive growth such as bloom formation, these bacteria can produce inherent toxins in quantities causing toxicity in mammals, including humans. These cyanotoxins include cyclic peptides and alkaloids.
