Toxins are a subset of toxicants. The term toxicant is preferred when the poison is man-made and therefore artificial. [14] The human and scientific genetic assembly of a natural-based toxin should be considered a toxin as it is identical to its natural counterpart. [15] The debate is one of linguistic semantics.
The most prominent natural toxin groups that exist in aquatic environments are mycotoxins, algal toxins, bacterial toxins, and plant toxins (8). These marine biotoxins are dangerous to human health and have been widely studied due to their high potential to bioaccumulate in edible parts of seafood.
Most channel-forming toxins, which form pores in the target cell membrane, can be classified into two families: the cholesterol-dependent toxins and the RTX toxins. Cholesterol-dependent cytolysins; Formation of pores by cholesterol-dependent cytolysins (CDC) requires the presence of cholesterol in the target cell. The size of the pores formed ...
A toxicologist working in a lab (United States, 2008)Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations. Neurotoxins inhibit neuron control over ion concentrations across the cell membrane, [6] or communication between neurons across a synapse. [13]
Ahead of RFK Jr.’s confirmation as head of the U.S. Department of Health and Human ... toxins and all the things that are carcinogenic that have been ignored in the United States," he said ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
