Disease relevance of Crustacea

• Effect of ambient oxygen concentration upon the acute toxicity of chlorophenols and heavy metals to the groundwater copepod Parastenocaris germanica (Crustacea) [1].

High impact information on Crustacea

• Although crustacean tissue cholesterol content is high, Crustacea, like other arthropods; are incapable of cholesterol synthesis, and presumably are dependent for maintaining tissue cholesterol stores on the intestinal absorption of ingested sterol [2].
• A new, simplified and overarching theory of noradrenaline function is inspired by an invertebrate model: neuromodulators in crustacea abruptly interrupt activity in neural networks and reorganize the elements into new functional networks determining the behavioral output [3].
• Blue/purple AXT proteins are ubiquitous among invertebrate marine animals, particularly the Crustacea [4].
• These findings allow consideration of MTH as a zinc thionein and question the view of all crustacea MT structures as copper thioneins [5].
• It is speculated that homarine is not only a "methyl" donor but may serve as a reservoir of methyl groups in crustacea [6].

Chemical compound and disease context of Crustacea

• A diverse set of reference compounds suspected of having an endocrine-disrupting mode of action (i.e., testosterone, flutamide, ethinylestradiol, precocene, nonylphenol, fenoxycarb, and methoprene) were tested for acute toxicity to the estuarine mysid Neomysis integer (Crustacea: Mysidacea) [7].
• Differences in the acute toxicities of tributyltin between the Caprellidea and the Gammaridea (Crustacea: Amphipoda) [8].
• Toxicity of toxaphene to Bosmina longirostris and Daphnia spp. (Crustacea) [9].
• Acute and chronic toxicity of Potassium Chloride (KCl) and Potassium Acetate (KC(2)H(3)O(2)) to Daphnia similis and Ceriodaphnia dubia (Crustacea; Cladocera) [10].

Biological context of Crustacea

• Large-scale gene rearrangements in the mitochondrial genomes of two calanoid copepods Eucalanus bungii and Neocalanus cristatus (Crustacea), with notes on new versatile primers for the srRNA and COI genes [11].
• Molecular population genetic diversity of two planktonic copepods of the North Atlantic, Calanus finmarchicus and Nannocalanus minor (Crustacea, Copepoda, Calanoida), was characterized using the sequence variation in a 350 bp region of the mitochondrial 16S rRNA gene [12].
• Bioconversion of desmosterol to cholesterol at various stages of molting cycle in Palaemon serratus Pennant, Crustacea, Decapoda [13].

Anatomical context of Crustacea

• Molecular cloning of a cDNA that encodes a serine protease with chymotryptic and collagenolytic activities in the hepatopancreas of the shrimp Penaeus vanameii (Crustacea, Decapoda) [14].
• An examination of the ability of inositol 1,4,5-trisphosphate to induce calcium release and tension development in skinned skeletal muscle fibres of frog and crustacea [15].
• Histamine has been proposed as a photoreceptor neurotransmitter in two major groups of arthropods, the insects and the crustacea [16].
• Hemolymph ecdysteroids and molt cycle in males and females of Siriella armata M-Edw. (Crustacea: Mysidacea): possible control by the MI-ME X-organ of the eyestalk [17].
• Colchicine, cytochalasin B, cyclic AMP, and pigment granule translocation in melanophores of Uca pugilator and Hemigrapsus oregonensis (Crustacea: Decapoda) [18].

Associations of Crustacea with chemical compounds

• IgE reactivity against a cross-reactive allergen in crustacea and mollusca: evidence for tropomyosin as the common allergen [19].
• It is found in primitive vertebrates, insects, and crustacea and has effects on growth and glucose uptake in animals low on the evolutionary ladder, yes even unicellular organisms [20].
• However, 5-HT has not been detected to date in Mysidacea (Crustacea, Peracarida) [21].
• How a low tissue O2 strategy could be conserved in early crustaceans: the example of the podocopid ostracods [22].
• Chitosan is a polysachharide consisting of copolymers of N-acetylglucosamine and glucosamine that is derived from chitin, a material found in the shells of crustacea [23].

Gene context of Crustacea

• Immunochemical and biochemical characterization of gastrin/cholecystokinin-like peptides in Palaemon serratus (Crustacea Decapoda): intermolt variations [24].
• An area of continued interest, but of no consensus or general findings, relates to the presence and inducibility of CYP1 family members in crustacea [25].
• Cytochromes P450 in crustacea [25].
• Regional variation in the spatial scale of selection at MPI* and GPI* in the acorn barnacle Semibalanus balanoides (Crustacea) [26].
• IgE-antibody reactivity to oysters and crustacea of sera from six oyster-sensitive, seven oyster- and crustacea-sensitive, and 12 crustacea-sensitive subjects was investigated [27].

Analytical, diagnostic and therapeutic context of Crustacea

• Evidence for the presence of serotonin in Mysidacea (Crustacea, Peracarida) as revealed by fluorescence immunohistochemistry [21].
• The distribution of metals within the hepatopancreas of Oniscus asellus (Crustacea, Isopoda) from two uncontaminated sites, and two sites contaminated with zinc, cadmium and lead, has been studied by atomic absorption spectrophotometry, light microscopy, transmission and scanning electron microscopy and X-ray microanalysis [28].
