(5) It was concluded that collagenase is a major factor in the aetiology of necrotic arachnidism.
(6) The geographical spread of Tegenaria agrestis spiders parallels the appearance of necrotic arachnidism in several areas.
(7) These intramembranous particle rows are novel structural modifications, called here 'linker' junctions, and are quite distinct from conventional tight or septate junctions found between the outer glial cells in more highly evolved arthropods such as the insects and arachnids.
(8) His Spider design is particularly fun, coming from "the interpretation of the ultimate heavy metal instrument through the lens of arachnids".
(9) There is an association of cytoskeletal components with these septate, linker, and tight junctions; the role of the cytoskeleton in tight junctions, which can be seen by freeze fracture to be based on simple ridges in insects or a more complex network of them in arachnids, may also be important in the regulation of paracellular permeability.
(10) Cross says that these arachnids, also known as vampire spiders, “love” feeding on human blood as it gives them an odour that renders them sexually attractive to potential mates.
(11) Guanine is the major nitrogenous waste product in arachnids.
(12) Ivermectin is a macrocyclic lactone (fermentation) product and actinomycete (Streptomyces avermitilis) that possesses an unusually broad spectrum of potent activity against several species of nematodes, arachnids, and insects that parasitize domestic animals.
(13) Necrotizing dermatitis, or arachnidism, is a new life-threatening syndrome of which many clinicians are unaware.
(14) A comparative analysis of cardiotropic activity of toxins has been studied in experiments on isolated heart of the poisonous animals from different systematic groups living on the territory of the USSR: reptiles (the venom of cobra, Vipera lebetina, Ancistrodon blomhoffi), amphibian (the venom of Bufo, Bombina, salamander), arachnids (the venom of Apis, Scolopendra, scorpion).
(15) Such a system is unknown in insects or crustaceans, but may be typical for arachnids.
(16) Similar to the heavily armoured arachnid seen in the E3 demo, it takes multiple hits to bring down, and coordinating fire from the three team members is crucial.
(17) Although they are very common arachnids, the scorpions (Euscorpius, sp.)
(18) Absorption spectra of visual screening pigments obtained in vitro with a microspectrophotometer using frozen sections are given for the insects Musca domestica, Phormia regina, Libellula luctuosa, Apis mellifera (worker honeybee only), Drosophila melanogaster (wild type only) and the arachnids Lycosa baltimoriana and Lycosa miami.
(19) Arachnidism can be manifested either through the skin or systemically.
(20) Since guanine is not only an essential constituent of vital nucleic acids, but also the main end product of nitrogenous waste excretion in arachnids, it is a potential candidate for a hygienic index for mite activity in house dust.
Chela
Definition:
(n.) The pincherlike claw of Crustacea and Arachnida.
Example Sentences:
