| different sensitivity of the sarcoplasmic reticulum ca(2+)-atpase enzyme to fluorescein-isothiocyanate in rabbit and carp muscles. | 1. carp and rabbit sarcoplasmatic reticulum ca(2+)-atpase enzymes were compared with respect to their sensitivity to fitc labelling. 2. the carp enzyme showed much lower sensitivity to fitc in the ca(2+)-mg2+ activated atpase activity. fifty percent inhibition was observed at 20 microm labelling fitc concentration; in rabbit enzyme this inhibition was already achieved at 2 microm fitc. 3. the tryptic cleavage products of the carp enzyme identified with immunoblot analysis as well as with fitc fl ... | 1992 | 1388116 |
| effects of polyoxyethylene (20) sorbitan monooleate on the acute toxicity of linear alkylbenzenesulfonate (c12las) to fish. | effects of polyoxyethylene (20) sorbitan monooleate (smoe20) on the acute toxicity of linear alkylbenzenesulfonate (c12las) to fish were investigated in red killifish (orizias latipes) and carp (cyprinus carpio). by adding polyoxyethylene sorbitan ester to c12las solution, the acute toxicity of c12las decreased. as a decreasing toxic effect of these nonionic surfactants, the depression of gill damage was histopathologically observed. no significant hematological and blood biochemical differences ... | 1992 | 1385076 |
| the effect of malathion, diazinon, and various concentrations of zinc, copper, nickel, lead, iron, and mercury on fish. | acute and chronic toxicity tests for malathion, diazinon, copper (cu), mercury (hg), lead (pb), zinc (zn), nickel (ni), and iron (fe) were conducted. mortalities of barilius vagra and cyprinus carpio (common carp) were variable but lc50-96 hr were similar for pesticides. adult b. vagra seem to be more sensitive to malathion than juvenile carp. both juvenile carp and adult b. vagra were extremely sensitive to diazinon. long-term exposure to pesticides modified morphology and behavior. the lc50-96 ... | 1992 | 1384613 |
| neuropeptides in the torus semicircularis of the carp (cyprinus carpio). | the distribution of fibers and cell bodies containing neurotensin, neurokinin a, galanin, or somatostatin-28(1-12) immunoreactivity in the torus semicircularis of the carp was studied using an indirect immunoperoxidase technique. in this mesencephalic region, a high-density of galanin-immunoreactive fibers was found, whereas neurokinin a or somatostatin-28(1-12)-immunoreactive processes were observed at a moderate density and neurotensin-immunoreactive fibers at a low density. cell bodies contai ... | 1992 | 1377585 |
| the effect of pesticides on carp (cyprinus carpio l). acetylcholinesterase and its biochemical characterization. | the activity and molecular forms of acetylcholinesterase (ache) were characterized in tissues of the carp (cyprinus carpio). tissue ache activity was determined in response to specific inhibitors (ethopropazine, bw 284 c51) or pesticides (cuso4, paraquat (pq), methidathion (md)). the highest ache activity was found in the serum (878 +/- 100 u/liter), followed by the brain (113 +/- 12 u/liter), heart (89 +/- 6 u/liter), and trunk muscle (35 +/- 5 u/liter). experiments with specific choline estera ... | 1992 | 1375147 |
| organization and nucleotide sequence of carp gonadotropin alpha subunit genes. | we have used pcr to amplify and align the sequence of two genes encoding cgth alpha. both genes comprise four exons and three introns. the organization of cgth alpha genes is very similar to that of mammalian gth alpha genes. however, the cgth alpha genes only span a region of 1.2 kb which is much smaller than those mammalian gth alpha genes. | 2003 | 1370380 |
| gene expression following transfection of fish cells. | various genes containing different transcriptional regulatory elements (tre) and the bacterial marker gene coding for chloramphenicol acetyl transferase were transfected into several fish cell lines to evaluate the efficiency of expression in comparison with mammalian cells. the cmv and rsv tre were the most efficient non-inducible promoters in directing reporter gene expression. rsv and cmv appeared of similar potency in a stable fish cell line. the human hsp-70 promoter showed high potency in ... | 1992 | 1369156 |
| development of expression vectors for transgenic fish. | genetic alteration of fish is important for aquatic biotechnology as well as for investigating molecular interactions that occur during vertebrate development. the numerous, large, transparent, and externally fertilized eggs of many fish species make them ideally suitable for genetic manipulation, especially for production of transgenic animals. genetic engineering of fish requires suitable expression vectors. accordingly, we developed two fish expression vectors, fv-1 and fv-2, which contain th ... | 2005 | 1366961 |
| an initial screen of a series of neuroactive peptides for activity on identified central neurones of helix aspersa. | 1. intracellular recordings were made from identified neurones in the suboesophageal ganglia of helix aspersa. seven neuropeptides were tested for activity and their actions compared with acetylcholine and fmrfamide. 2. three peptides isolated from nematodes, af-1, af-2 and pan-1 had mainly inhibitory effects with thresholds of around 1 nm. this inhibition was due to an increase in potassium conductance. 3. the molluscan neuropeptides lssfvriamide, carp and acep-1 were all active on certain neur ... | 1992 | 1363295 |
| effects of hypoxia on renal function in carp, cyprinus carpio. | 1. changes in urine and blood properties and heart rate (hr) of carp were investigated during and following hypoxia. 2. when carp were exposed to hypoxic conditions, urine flow in some carp increased immediately. however, it decreased gradually with time. osmotic pressure and na+, cl-, ca2+ and mg2+ levels in urine increased in contrast to urine flow. k+, p, ammonium, and lactic acid levels in urine increased gradually. 3. when carp lost their balance, blood ph and plasma k+ were lower, and rbc, ... | 1992 | 1351452 |
| xenobiotic-metabolizing enzyme systems in test fish--iv. comparative studies of liver microsomal and cytosolic hydrolases. | 1. the initial slopes of the substrate-activity curves of several hydrolases were determined in the microsomal and cytosolic fractions of the liver of several fish recommended by oecd for the regulatory testing of chemicals. 2. inter-species differences ranged within a factor of 7-17 for the esterases and reached a factor of 60 for the amidase. guppy and carp appeared endowed with hydrolase activities which, overall, are much higher than zebra fish, trout and golden orfe. 3. the comparison with ... | 1992 | 1350956 |
| immunochemical characterization of rat testicular asparagine synthetase. | we studied immunochemical properties of rat testicular asparagine synthetase. western blot analysis of testis extract with polyclonal antibody raised against purified asparagine synthetase revealed an immunoreactive band at 62 kda. the pancreas, brain, thymus, and spleen also showed 62-kda bands. the intensities of these bands were roughly proportional to the specific activities of the enzyme in these tissues. the antibody showed some degree of cross-reactivity to asparagine synthetases from hum ... | 1992 | 1349469 |
| mechanisms for anoxic survival in the vertebrate brain. | when energy supplies to the mammalian brain are significantly reduced by anoxia, for a very short time energy requirements are curtailed by such routes as the suppression of synaptic transmission, while energy supply is enhanced by an increase in cerebral blood flow and an increase in glycolysis. the reduction of atp consumption is insufficient to match the greatly curtailed supply of atp coming from anaerobic glycolysis and the hydrolysis of pcr, and within minutes atp falls, there is a loss of ... | 1992 | 1348613 |
| oral absorption of biologically active insulin in common carp (cyprinus carpio l.). | 1. bovine insulin dissolved in 0.05 m deoxycholic acid was absorbed through oral intubation in fish weighing 200-300 g. 2. the peak of absorption appeared in all fish, 30-45 min after intubation and was followed by a gradual decrease. the extent of absorption was extremely variable, with up to a 20-fold difference between individuals. no detectable insulin was found in fish intubated with vehicle. 3. the absorbed hormone retained 17-88% of its lipogenic bioactivity in vitro. the absorbed insulin ... | 1992 | 1347729 |
| [production of a carp-based hamburger-like product by reducing the water activity]. | the experimental conditions were determined in order to conserve lean fish by means of combined factors based on aw and ph reduction as well as the addition of an antifungal. theoretical aw was determined in formulas containing fish, sodium chloride, glycerol and sorbitol applying a mathematic model. from the results of the prediction, 4 formulas were prepared experimentally with (cyprinus carpio). phosphoric acid was added to the products in order to obtain a 5.5-6.0 ph. the final formulas were ... | 1992 | 1341858 |
| switches in fish myosin genes induced by environment temperature in muscle of the carp. | fish are cold blooded animals and their muscle function is expected to be greatly affected by environmental temperature. species that live in the antarctic ocean have evolved a different contractile system to fish that live in the tropical waters. in the case of antarctic fish they have a higher specific myofibrillar atpase activity but 'the trade off' seems to be a lower thermal stability. they are thus capable of a greater muscle power output at low temperatures but the lower thermal stability ... | 1992 | 1341032 |
| electroporation: a method for transferring genes into the gametes of zebrafish (brachydanio rerio), channel catfish (ictalurus punctatus), and common carp (cyprinus carpio). | recombinant plasmids containing the rous sarcoma virus long-terminal repeat (rsvltr) promoter linked to either rainbow trout (oncorhyncus mykiss) growth hormone 1 (rtgh1) or growth hormone 2 (rtgh2) cdna were linearized and introduced into the fertilized eggs of zebrafish (brachydanio rerio), channel catfish (ictalurus punctatus), and common carp (cyprinus carpio) by both electroporation and microinjection. the latter two species had these rainbow trout constructs (rsvltr-rtgh1cdna or rsvltr-rtg ... | 1992 | 1339228 |
| low concentrations of neuroactive peptides modulate cholinergic transmission and cyclic amp levels in helix aspersa. | 1. fmrfamide and the catch relaxing peptide (carp) at 0.01-0.1 nm modulate acetylcholine (ach) induced currents of identified neurons of helix aspersa, but have no direct effect on membrane current and conductivity. 2. both fmrfamide and carp noncompetitively inhibit ach cl- responses while having either no effect or increasing ach na+/k+ response. 3. the inhibitory effect of fmrfamide and carp on the ach cl- response was eliminated following pretreatment with forskolin (20 microm), an activator ... | 1992 | 1338559 |
| dopamine decreases receptive field size of rod-driven horizontal cells in carp retina. | receptive field size of rod-driven horizontal cells (hcs) in the carp retina was measured by the spread of responses to the slit of light stimulus with changing the distance from the recording electrode and it was found to decay with a single exponential function. by perfusing 10 microm dopamine (da) the length constant of rod-driven hcs was reduced to half and the response amplitude in the centre increased approximately two-fold, and the input resistance was markedly increased. this suggests th ... | 1992 | 1337637 |
| [the characteristics of carbohydrate transport in the intestines of fresh-water fishes]. | the maximal level of carbohydrate transport was found in the proximal portion of the intestine and in the distal one in the bream and carp. after 48-hr starvation the carbohydrate transport was decreased along the whole length of the intestine. anoxia and some inhibiting agents changed the intensity of glucose and galactose transport in the fish intestine. | 1992 | 1335912 |
| the effects of atp, inorganic phosphate, protons, and lactate on isolated myofibrillar atpase activity. | the purpose of this study was to examine the effects of lactate, protons, inorganic phosphate, and atp on myofibrillar atpase activity. myofibrils were isolated from carp (cyprinius carpio l.) fast-twitch white muscle, and myofibrillar atpase activities were assessed under maximal activating calcium levels (pca 4.0) at 10 degrees c in reaction media containing metabolic profiles similar to those seen in fatiguing muscles. the ca(2+)-activated atpase activity was assessed by an atp regenerating a ... | 1992 | 1335356 |
| phototransduction in cones as examined in excised membrane patch. | phototransduction mechanisms have been so far investigated mostly in rods, whereas those in cones are much less known. in the present experiment, we investigated phototransduction mechanisms in inside-out patches excised from cone outer segments of the carp. cyclic gmp-activated channels on the patch became light-sensitive when both gtp and mg2+ were supplied by perfusion. when the channels were activated by a hydrolysis-resistant analogue of cgmp, activities were not suppressed by light even th ... | 1992 | 1331581 |
| characterization of gonadotropin-releasing hormone (gnrh) receptors in the ovary of common carp (cyprinus carpio). | gonadotropin-releasing hormone (gnrh) binding sites have been characterized in the fully mature common carp ovary, using an analog of salmon gnrh ([d-arg6,trp7,leu8,pro9-net]-gnrh; sgnrh-a) as a labeled ligand. binding of sgnrh-a to carp follicular membrane preparation was found to be time-, temperature-, and ph-dependent. optimal binding was achieved after 40 min of incubation at 4 degrees c at ph 7.6; binding was found to be unstable at room temperature. binding of radioligand was a function o ... | 1992 | 1325864 |
| [effects of prolonged darkness and background illumination on cone horizontal cells in carp retina: a correlative study of morphology and physiology]. | using intact, immobilized carp preparations, changes in light responsiveness of cone horizontal cells and ultrastructures of their terminals in cone pedicles (hcts) were correlatively examined in prolonged (greater than 2 h) darkness and after the presentation of a dim background light. following background illumination cone horizontal cells exhibit high light responsiveness and hcts give rise to a lot of long, fingerlike or ball-like extensions, called slender or round spinules. when the retina ... | 1992 | 1320293 |
| m-phase-specific histone h1 kinase in fish oocytes. purification, components and biochemical properties. | we demonstrate, for the first time in fish, that a ca(2+)-independent and cyclic-nucleotide-independent histone h1 kinase activity oscillates according to the cell cycle of the oocyte, peaking at the first and the second meiotic metaphase with a transient drop between them. the kinase, m-phase-specific histone h1 kinase (m-h1k), was purified from mature carp oocytes by using two exogenous substrates for assaying its activity: histone h1 and a synthetic peptide (sp peptide, kkaakspkkakk) containi ... | 1992 | 1315270 |
| selection of promoters for gene transfer into fish. | a variety of gene constructs containing carp beta-actin regulatory sequences were tested for their ability to drive transient expression of the chloramphenicol acetyltransferase reporter gene in 3 fish cell lines: carp epithelial cells (epc), rainbow trout hepatoma cells (rth149), and rainbow trout fibroblasts (rtg2). the constructs showed a wide variation in their levels of expression, and there were significant differences in the effects of transcriptional elements in the 3 cell lines. sequenc ... | 2008 | 1308823 |
| fish transgene expression by direct injection into fish muscle. | the ability of a promoter sequence to drive expression of a reporter gene can be determined by direct injection of copies of the cloned sequence into fish muscle, followed by biopsy of muscle from the site of injection. we describe a set of experiments in which copies of the constructs fv1 and fv2, both comprising a carp beta-actin promoter sequence spliced to the bacterial reporter gene cat, were injected into the muscle of tilapia fish )oreochromis niloticus) of between 5 and 8 cm body length. ... | 1992 | 1308819 |
| introducing foreign genes into fish eggs with electroporated sperm as a carrier. | a new method has been developed for introduction of foreign genes into fish eggs. the procedure is based on the incubation of fish sperm cells suspended in dilute citrate solution with plasmid dna, followed by application of high-field-strength electrical pulses (electroporation) to increase dna binding., uptake, or both. tissue homogenates and genomic dna extracts of free swimming fry developed from eggs fertilized with treated sperm was tested to evaluate the efficiency of gene transfer. dot b ... | 2012 | 1308817 |
| isolation and sequence analysis of carp gonadotropin beta-subunit gene. | using the cdna encoding the beta subunit of carp gonadotropin (cgth-beta) as a probe, 14 clones containing cgth-beta gene have been isolated from a carp genomic library. nucleotide sequence analysis indicated that the transcriptional unit of the cgth-beta gene is 1.2 kb. similar to mammalian gth-beta genes, cgth-beta gene contains three exons and two introns. the locations of the exon/intron junctions also correspond to those of mammalian gth-beta gene. using the primer extension assay, the star ... | 1992 | 1308812 |
| chemical identification of catfish growth hormone and prolactin. | isolation and primary structure of growth hormone (gh) and prolactin (prl) from the pituitary gland of catfish (ictalurus punctatus) are described. alkaline extract of the pituitary glands was fractionated by gel filtration on sephadex g-75, ion-exchange chromatography on deae-cellulose, and reversed-phase high-performance liquid chromatography on octadecyl silica ods. catfish gh and prl were identified by western blotting with antisera against chum salmon gh and prl. the catfish gh consists of ... | 1992 | 1308206 |
| protease activities in carp retina. | protease of carp retina were examined by electrophoresis and fluorogenic assays. a 70 kd serine protease with an alkaline ph optimum was detected in gelatin-containing polyacrylamide gels. a similar enzyme was found in carp brain and muscle, but not in lens. using aminomethylcoumarin (mca) substrates, activities that hydrolysed z-phe-arg-mca, boc-ala-gly-pro-arg-mca and various aminoacyl-mcas were detected. the z-phe-arg-mca hydrolase was an acidic cysteine protease, whereas the boc-ala-gly-pro- ... | 1992 | 1303734 |
| peptidergic regulation of muscle movements in a prosobranch mollusc, rapana thomasiana. | peptidergic regulation of the contraction of radula muscles and the heart beat in a prosobranch mollusc, rapana thomasiana was investigated. in the radula muscles, fmrfamide-related peptides were suggested to act on presynaptic sites to enhance their contraction elicited by nerve stimulation, possibly by increasing the release of a main transmitter. a catch-relaxing peptide (carp) was demonstrated to depress the contraction by acting on postsynaptic sites. in the heart, fmrfamide enhanced the am ... | 1992 | 1299108 |

| [evoked potentials in the optic tectum of the carp brain upon electric stimulation of the facial nerve]. | the evoked potentials in the carp tectum opticum in response to stimulation of the afferent pathway for chemical nonolfactory reception, the facial nerve, are positive deflections of 5-25 ms latency which do not reverse during microelectrode submersion. according to the evoked potential amplitude and latent period 7 active zones were distingnished in the ipsilateral tectum differing from each other either in one or in both parameters. the dependence of the response evoked by facial nerve stimula ... | 1976 | 1264291 |
| a somatotopic and functional representation of the respiratory muscles in the trigeminal and facial motor nuclei of the carp (cyprinus carpio l.). | the place of the cells innervating six most important respiratory muscles in the carp (cyprinus carpio l.) were determined by means of the horseradish peroxidase technique. it was found that these muscles are represented in the rostral and caudal subdivisions of the trigeminal and facial motor nuclei. all connections were ipsilateral. the distribution of the various cell populations over the different subnuclei has been related to the function of the respective muscles in the respiratory cycle. ... | 1976 | 1262554 |
| effects of calcitonin and ultimobranchialectomy (ubx) on calcium and bone metabolism in the eel, anguilla anguilla l. | prolonged administration of synthetic salmon calcitonin (sct) to immature female silver eels, maintained in sea water, provoked a decrease of the serum calcium concentration and an increase of both the osteoblastic apposition and of the degree of mineralization of the intercellular matrix in the vertebral bone. the osteoclastic resorption and osteocytic osteolysis were not significantly affected, however the osteoclastic index was reduced. the ultimobranchial body, site of ct secretion, was caut ... | 1976 | 1260486 |
| polymorphism of transferrin in carp (cyprinus carpio l.): genetic determination, isolation, and partial characterization. | seven transferrin variants (a,b,c,d,e,f, and g) have been found in carp sera (cyprinus carpio l.). genetic analysis involves five variants and agrees with the hypothesis of simple codominant autosomal inheritance at one transferrin (tf) locus in spite of the fact that the carp is a tetraploid in relation to other species of the same family. carp populations from three regions were studied which differed in gene frequencies. individual populations were in hardy-weinberg equilibrium. the polymorph ... | 1976 | 1259703 |

| [peptide hydrolase activity during embryonic carp development]. | it was established that in the carp the process of embryonic and early postembryonic development was accompanied by the increase in the activity of both the trypsin- and chemotrypsin-like peptide hydrolases. this increase is most evident in larvae with resorbing yolk. the total and protein nitrogen content suffers no changes during embryonic and early postembryonic development. the content of non-protein nitrogen increases from the stage of the middle of segmentation on attaining the maximum lev ... | 1975 | 1214997 |
| water flow dynamics in the respiratory tract of the carp (cyprinus carpio l.). | simultaneous measurements of water velocity in the buccal chamber, and buccal and opercular hydrostatic pressure of carp have revealed surprisingly high water velocities. the high flow velocities mean that, at times, the kinetic energy of flow makes a substantial contribution to the total fluid energy. this suggests that there may be unequal distribution of hydrostatic pressures within the buccal chamber. anatomical examinations showed that fluid channels in the buccal chamber and gill raker sie ... | 1975 | 1214116 |
| the use of carp, cyprinus carpio (linnaeus, 1758), instead of rabbit as antibody donor in immunological research on fishes. | antisera produced by carp were tested in the differentiation between two cyprinid fishes, bream and roach, and between the lipovitellins of two grey mullets, mugil cephalus and liza ramada. these antisera were more specific in the recognition of different fish species than those produced by rabbits. an antiserum against carp lipovitellin was produced with male carp as antibody donor. | 1975 | 1211668 |
| [structural and immunochemical studies of the immunoglobulins of carp (cyprinus carpio l.) ii. analysis of the subunits]. | the 14 s immunoglobulin of the carp (cyprinus carpio l.) was split into subunits with 0,01 m dithioerythritol. these 5,7 s subunits have a molecular weight of 104 000 and a hexose and hexosamine content of 6.2%. it is likely that the subunits represent hl-half-molecules and not h2l2-monomeres. the values for the molecular of h- and l-chains were 77 000 and 24 000, respectively. | 1975 | 1210999 |
