Seth Eugene Meek
Seth Eugene Meek (April 1, 1859, Hicksville, Ohio – July 6, 1914, Chicago) was an American ichthyologist at the Field Museum of Natural History in Chicago. He was the first compiler of a book on Mexican freshwater fishes. Together with his assistant, Samuel F. Hildebrand, he produced the first book on the freshwater fishes of Panama. He often collaborated with Charles H. Gilbert, and in 1884 on a collecting trip through the Ozarks, they discovered a new species, ''Etheostoma nianguae'', which only lives in the Osage River basin. Also with them on that excursion was David Starr Jordan, considered the father of modern ichthyology. After the Ozarks trip, Meek accepted the post of professor of biology and geology at Arkansas Industrial University (now the University of Arkansas). Tribute The American halfbeak The American halfbeak (''Hyporhamphus meeki''), also known as Meek's halfbeak, is a halfbeak from the family Hemiramphidae. Its specific name is in honor of American ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurotoxic
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant– alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue. This can eventually disrupt or even kill neurons, which are cells that transmit and process signals in the brain and other parts of the nervous system. Neurotoxicity can result from organ transplants, radiation treatment, certain drug therapies, recreational drug use, and exposure to heavy metals, bites from certain species of venomous snakes, pesticides, certain industrial cleaning solvents, fuels and certain naturally occurring substances. Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/o ...

Crotalus Viridis Southern Pacific Rattlesnake Juvenile
''Crotalus'' is a genus of venomous pit vipers in the family Viperidae, known as rattlesnakes or rattlers. Wright AH, Wright AA (1957). ''Handbook of Snakes of the United States and Canada''. Ithaca and London: Comstock Publishing Associates (7th printing, 1985). 1,105 pp. (in 2 volumes). . The genus is found only in the Americas from southern Canada to northern Argentina, and member species are colloquially known as rattlesnakes. The generic name ''Crotalus'' is derived from the Greek word ''krótalοn'', which means "rattle" or "castanet", and refers to the rattle on the end of the tail, which makes this group (genera ''Crotalus'' and ''Sistrurus'') so distinctive.Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 870 pp. 1,500 plates. . Currently, 32 to 45 species are recognized as being valid.

Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. ''Crossbreeding'', sometimes called "designer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ' ...

Antivenom
Antivenom, also known as antivenin, venom antiserum, and antivenom immunoglobulin, is a specific treatment for envenomation. It is composed of antibodies and used to treat certain venomous bites and stings. Antivenoms are recommended only if there is significant toxicity or a high risk of toxicity. The specific antivenom needed depends on the species involved. It is given by injection. Side effects may be severe. They include serum sickness, shortness of breath, and allergic reactions including anaphylaxis. Antivenom is traditionally made by collecting venom from the relevant animal and injecting small amounts of it into a domestic animal. The antibodies that form are then collected from the domestic animal's blood and purified. Versions are available for spider bites, snake bites, fish stings, and scorpion stings. Due to the high cost of producing antibody-based antivenoms and their short shelf lives when not refrigerated, alternative methods of production of antivenom ...

Crotalidae Polyvalent Immune Fab
Crotalidae polyvalent immune fab, sold under the brandname CroFab, is a snake antivenin, indicated for minimal or moderate North American Crotalid (Rattlesnake, Copperhead and Cottonmouth/Water moccasin) snake envenomation. CroFab is composed of several monovalent Fragment antigen-binding proteins (Fab) derived from the blood of sheep immunized with one of four snake venom: ''Crotalus atrox'' (western diamondback rattlesnake), ''Crotalus adamanteus'' ( Eastern diamondback rattlesnake), ''Crotalus scutulatus'' (Mojave rattlesnake), or ''Agkistrodon piscivorus'' (Cottonmouth or Water Moccasin). Each monospecific antivenin is purified from sheep serum, digested with the enzyme papain, and purified further resulting in specific Fab fragments. The resulting four different Fab preparations are mixed to formulate the final product. Background It was developed by the Venom Immunochemistry, Pharmacology and Emergency Response (VIPER) Institute, University of Arizona, and commercial ...
