| synthesis of nonmammalian angiotensins and their comparative pressor properties in dogfish shark, domestic chicken, and rat. | to understand how vertebrates utilize angiotensins during evolutionary development, we undertook studies to synthesize and/or characterize angiotensin-like peptides from nonmammalian species. the present paper describes the synthesis of [asp1,val5,asn9] angiotensin i (bull frog, rana catesbeiana) (i), [asn1,val5,his9] angiotensin i (japanese goosefish, lophius litulon) (ii), [asn1, val5,asn9] angiotensin i (chum salmon, oncorhynchus keta) (iii), and [asn1, val5,tyr9] angiotensin i (related to na ... | 1983 | 6654463 |
| a microsporidian parasite of the genus spraguea in the nervous tissues of the japanese anglerfish lophius litulon. | in the present study, a high percentage of japanese anglerfish, lophius litulon (jordan, 1902), contained a microsporidian infection of the nervous tissues. xenomas were removed and prepared for standard wax histology and transmission electron microscopy (tem). dna extractions were performed on parasite spores and used in pcr and sequencing reactions. fresh spores measured 3.4 x 1.8 microm and were uniform in size with no dimorphism observed. tem confirmed that only a single developmental cycle ... | 2004 | 15357394 |

| description and phylogeny of ceratomyxa anko sp. n. and zschokkella lophii sp. n. from the japanese anglerfish, lophius litulon (jordan). | two new species of myxozoans from the japanese anglerfish, lophius litulon, are described using myxospore morphology and small subunit rdna sequences. ceratomyxa anko sp. n. is a parasite of the gall bladder and had a prevalence of 57%. mature spores of c. anko sp. n. are arcuate to crescent shaped with valves tapering to rounded tips. a prominent sutural line runs centrally between the round adjacent polar capsules containing the polar filament coiled two to three times. spore measurements: len ... | 2008 | 18803583 |
| inaccuracy of labeling and visual inspection for microsporidian parasites in anglerfish lophius litulon (jordan, 1902) collected from chinese retail markets in sardinia, italy. | the aim of the present study was to evaluate the accuracy of labeling and the efficacy of visual inspection to detect the lesions by visible parasites in anglerfish lophius litulon. one hundred samples were collected over a 2-year period (2011 to 2012) from chinese retail markets in sardinia, italy. to assess the conformity of the items with the trade name, a preliminary visual inspection of the samples by a simple morphological analysis was performed. according to the council regulations (ec) 1 ... | 2015 | 26038919 |
| [effects of macro-jellyfish abundance dynamics on fishery resource structure in the yangtze river estuary and its adjacent waters]. | based on the bottom trawl survey data in may 2007 and may and june 2008, this paper analyzed the effects of the abundance dynamics of macro-jellyfish on the species composition, distribution, and abundance of fishery resource in the yangtze river estuary and its adjacent waters. from may 2007 to june 2008, the average catch per haul and the top catch per haul of macro-jellyfish increased, up to 222.2 kg x h(-1) and 1800 kg x h(-1) in june 2008, respectively. the macro-jellyfish were mainly distr ... | 2011 | 22384604 |
| purification and sequence characterization of chondroitin sulfate and dermatan sulfate from fishes. | chondroitin sulfate (cs) and dermatan sulfate (ds) were extracted and purified from skins or bones of salmon (salmo salar), snakehead (channa argus), monkfish (lophius litulon) and skipjack tuna (katsuwonus pelamis). size, structural sequences and sulfate groups of oligosaccharides in the purified cs and ds could be characterized and identified using high performance liquid chromatography (hplc) combined with orbitrap mass spectrometry. cs and ds chain structure varies depending on origin, but m ... | 2017 | 28091940 |
| hysterothylacium simile n. sp. and h. aduncum (rudolphi, 1802) (nematoda: raphidascarididae) from marine fishes in the bohai and yellow sea, china, with comments on the record of h. paralichthydis (yamaguti, 1941) from chinese waters. | hysterothylacium simile n. sp., collected from the japanese seabass lateolabrax japonicus (cuvier) (perciformes: lateolabracidae) in the bohai sea off china, is described using both light and scanning electron microscopy. the new species differs from its congeners in the presence of narrow lateral alae originating a short distance posterior to the base of the ventrolateral lips, a long intestinal caecum (60.4-79.1% of oesophageal length) and a relatively short ventricular appendix (intestinal ca ... | 2013 | 23263941 |
