fine structure of monoamine-containing basal cells in the taste buds on the barbels of three species of teleosts.the taste buds on the barbels in three species of teleosts (cyprinus carpio, misgurnus anguillicaudatus, parasilurus asotus) were studied by means of fluorescence- and electron microscopy. intensely yellow-fluorescent cells, which are disk-shaped and located exclusively in a basal position, are observed in the barbel-buds of all fishes examined. the basal cells contain a large number of small clear vesicles approximately 40-60 nm in diameter, which show a tendency to aggregate in the cytoplasm f ...19846713479
[studies on intestinal trematodes in korea xiv. infection status of loaches with metacercariae of echinostoma cinetorchis and their development in albino rats]the metacercariae of echinostoma cinetorchis (trematoda: echinostomatidae) were found infected in the loaches (misgurnus anguillicaudatus) purchased from two local markets in korea. identification of the metacercariae was done after obtaining adult worms from experimentally infected albino rats. brief course of worm development in rats was also observed up to 28th post-infection day. the results are as follows: the metacercariae of e. cinetorchis were detected from 5 (10.9 %) out of 46 loaches e ...198412891011
cdna cloning and expression characterization of serum transferrin gene from oriental weatherfish misgurnus this study, the cdna coding serum transferrin (stf) of misgurnus anguillicaudatus (mastf) was cloned. mastf cdna is composed of 2326 bp with a 2007 bp open reading frame encoding 668 amino acids. the deduced mastf protein consists of a signal peptide, two lobes (n and c-lobes) and signature motifs of transferrin (tf) family. the results of tissue distribution indicated that mastf mrna was predominantly expressed in the liver. the results indicate that the mastf expression increased significan ...201424673686
co-expression of calcium signaling components in vertebrate taste bud order to investigate the molecular mechanism of calcium signaling pathways common to the vertebrate gustatory systems, we have analyzed the expression of their molecular components. we first identified a phospholipase c (plc) beta subtype expressed in the taste buds of pond loach (misgurnus anguillicaudatus), designated dplcbeta2, which is closely related to mammalian plcbeta2 shown recently to be expressed in rat taste buds. the taste bud-specific expression of plcbeta2 in a fish species as ...200010729634

prevalence of clonorchis sinensis infection in freshwater fishes in northeastern china.the prevalence of clonorchis sinensis infection in freshwater fishes was surveyed in heilongjiang province, northeastern china, between august 2011 and september 2013. thirteen species of freshwater fish (n=3221) and one species of shrimp (n=93) were collected from songhua river, nenjiang river and other lakes or ponds in 37 sites of 15 representative cities in heilongjiang province. they were individually examined by digestion technique, and the c. sinensis metacercariae were identified morphol ...201424880648
proteocephalid tapeworms (cestoda: onchoproteocephalidea) of loaches (cobitoidea): evidence for monophyly and high endemism of parasites in the far east.the parasite fauna of loaches (cypriniformes: cobitoidea), a group of small bottom-dwelling freshwater fishes with a mostly eurasian distribution, remains a largely unknown quantity. here we revise the taxonomy of tapeworms of the genus proteocephalus weinland, 1858 (cestoda: proteocephalidae) that had been found in loaches from the palaearctic region (central europe, japan and russia [primorsky region]). molecular phylogenetic analysis based on two nuclear (ssr- and lsrdna) and two mitochondria ...201727702602
a restoration-promoting integrated floating bed and its experimental performance in eutrophication remediation.numerous studies on eutrophication remediation have mainly focused on purifying water first, then restoring submerged macrophytes. a restoration-promoting integrated floating bed (rpifb) was designed to combine the processes of water purification and macrophyte restoration simultaneously. two outdoor experiments were conducted to evaluate the ecological functions of the rpifb. trial 1 was conducted to compare the eutrophication purification among floating bed, gradual-submerging bed (gsb) and rp ...201425079639
resting metabolism and heat increment of feeding in mandarin fish (siniperca chuatsi) and chinese snakehead (channa argus).resting metabolism was measured in immature mandarin fish siniperca chuatsi weighing 42.1-510.2 g and chinese snakehead channa argus weighing 41.5-510.3 g at 10, 15, 20, 25, 30 and 35 degrees c. heat increment of feeding was measured in mandarin fish weighing 202.0 (+/-14.0) g and snakehead weighing 200.8 (+/-19.3) g fed swamp loach misgurnus anguillicaudatus at 1% body weight per day at 28 degrees c. in both species, weight exponent in the power relationship between resting metabolism and body ...200011064280
molecular evidence of cryptic diversity in paracaryophyllaeus (cestoda: caryophyllidea), parasites of loaches (cobitidae) in eurasia, including description of p. vladkae n. sp.molecular phylogenetic analysis of an extensive collection of monozoic tapeworms of the genus paracaryophyllaeus kulakovskaya, 1961 (cestoda: caryophyllidea), parasites of loaches (cypriniformes: cobitidae) in eurasia, has revealed cryptic species diversity within this long-time monotypic genus, especially in the paracaryophyllaeus gotoi (motomura, 1927) species complex [syn. paracaryophyllaeus dubininorum (kulakovskaya, 1961); type species]. three independent, well-supported clades were discove ...201425111941
clonal diploid sperm of the diploid-triploid mosaic loach, misgurnus anguillicaudatus (teleostei:cobitidae).the loach misgurnus anguillicaudatus comprises diploid, triploid and diploid-triploid mosaic individuals in a wild population of the hokkaido island, japan. previous studies revealed the presence of a cryptic clonal lineage among diploid loaches, which is maintained by uniparental reproduction of genetically identical diploid eggs. in the present study, we analyzed distribution and genetic status of diploid and triploid cells in infrequent mosaic males. flow cytometry, microsatellite genotyping ...200415181644
