| duplication 6q syndrome. | duplication (partial trisomy) of the long arm of chromosome 6 has been described in 5 children [robertson et al, 1975, chen et al, 1976, clark, 1977]. we wish to report here an additional case due to a familial translocation in which the proband's karyotype is 46,xx,der(3),rcp(3;6)(p25;q21)mat. the phenotypes of the 6 children with duplication 6q are strikingly similar. each child has duplication involving approximately the distal 1/3 to 1/2 of the long arm of chromosome 6. distinctive features ... | 1979 | 474632 |
| anti-idiotypic antibodies of igm-type produced in carp (cyprinus carpio l.). | carp synthesize highly specific anti-idiotypic antibodies of the igm class. ant-idiotypic antibodies could be elicited in these animals by a human igm myeloma protein and were detected in a passive hemagglutination assay. the agglutination was completely inhibited by approximately 0.15 microgram homologous antigen, whereas a 100 000-fold excess of a heterologous igm myeloma protein of the same l chain type did not produce any inhibition. a possible subgroup specificity of carp anti-idiotypic ant ... | 1979 | 499328 |
| non-repetitive dna sequence divergence in phylogenetically diploid and tetraploid teleostean species of the family cyprinidae and the order isospondyli. | non-repetitive dna of anciently tetraploid teleostean species was analysed for the presence of duplicated sequences. closely related diploid species were investigated in comparison. from the reassociation kinetics of total nuclear dna, rate constants and fraction sizes of classes of repetitive and non-repetitive sequences were determined. dna fractions enriched in the slowest renaturing sequence class were determined. dna fractions enriched in the slowest renaturing sequence class were prepared ... | 1979 | 533669 |

| vitamin a transport in plasma of the non-mammalian vertebrates: isolation and partial characterization of piscine retinol-binding protein. | studies were conducted to explore vitamin a transport in the non-mammalian vertebrates, especially pisces, amphibia, and reptilia, and to isolate and partially characterize piscine retinol-binding protein. retinol-containing proteins in fresh plasma obtained from bullfrogs and a turtle exhibited similar properties to those found in mammalian and chicken plasma: i.e., molecular weight of about 60,000-80,000 as estimated by gel filtration and binding affinity to prealbumin on human prealbumin-seph ... | 1977 | 562910 |
| spring viremia of carp virus rna and virion-associated transcriptase activity. | an rna-dependent rna polymerase activity has been demonstrated for spring viremia of carp virus (svcv). the optimal temperature for in vitro synthesis of rna was 20 to 25 degrees c. the svcv enzyme activity was stimulated when the methyl donor s-adenosyl-l-methionine was included in the reaction mixture. s-adenosyl-l-methionine was not particularly effective in stimulating the virion rna polymerase activity of vesicular stomatitis virus or pike fry rhabdovirus. the 5' nucleotide of the svcv vira ... | 1978 | 565417 |
| histone proteolysis in fish erythrocyte nuclei. | the erythrocyte histones of trout, carp, white sucker, and chicken are subject to very different levels of autolytic activity. carp erythrocyte histones extracted from typical nuclear preparations suffer extensively from degradation; histones 1, 5, and 3 (h1, h5, and h3 respectively) are preferentially cleaved and characteristic peptides designated p1, p2, and p3 appear during the course of proteolysis. generally, erythrocytes from different fish species yield highly disparate proportions of h1 ... | 1977 | 597770 |

| regulatory effect of temperature and antigen upon immunity in ectothermic vertebrates. ii. primary enhancement of anti-hapten antibody response at high and low temperatures. | enhancement of primary anti-hapten antibody response was more efficient when carp were preimmunized with modified carrier, rather than with its native form, especially when they were challenged with a slightly substituted penicilloyl-bsa conjugate (pen5 bsa). no significant enhancement was obtained when the fish were challenged with a heavy conjugate (pen30 bsa). when fish kept at optimal temperature were preinjected with the modified carriers, rising titers of anti-hapten antibodies were obtain ... | 1977 | 611022 |
| the monoamine-containing cell in the gustatory epithelium of some vertebrates. | fluorescence histochemistry has revealed that a specific formaldehyde-induced yellow fluorescence, suggesting the presence of serotonin-like monoamines, was regularly observed in a group of cells (monoamine-containing cells: mc cells) in the normal gustatory epithelia of the carp, catfish, frog and rabbit. the present report was also concerned with the ultrastructural features of the mc cell in the rabbit's foliate bud. the mc cells were found to have synaptic contacts with the intragemmal nerve ... | 1977 | 615562 |
| partial trisomy of the short arm of chromosome 7 due to a familial translocation rcp(7;14)(p11;p11). | a boy with trisomy of the short arm of chromosome 7 is reported. he presented several congenital malformations, such as: dolicocephaly; wide fontanelle; hypertelorism; antimongoloid slanting of the palpebral fissures; small, carp-shaped mouth; thin neck; extrinsic compression of the oesophagus; congenital dislocation of the shoulders and hips; and a possible cardiac defect. the proband's mother had a balanced translocation involving the short arm of chromosomes 7 and 14. in this family the trans ... | 1978 | 699358 |
| primary structure of hemoglobin from trout (salmo irideus). amino acid sequence of alpha chain of hb trout i. | the amino acid sequence of the alpha chain of the hemoglobin component of trout's blood which is devoid of heterotropyc phenomena, i.e. hb trout i, is presented. the sequence has been determined by analyzing the soluble tryptic peptides obtained from the whole globin and the peptides obtained after redigesting the insoluble 'core' with chymotrypsin. alignment of the peptides with the structure of human as well as carp and catostomus clarkii alpha chains shows that hb trout i alpha chain differs ... | 1978 | 708770 |
| radioelectrophoresis: a specific microassay for parvalbumins. application to muscle biopsies from man and other vertebrates. | a two-dimensional radioelectrophoretic method is described, by which parvalbumins from minute biopsy samples (approx. 50 mg) can be detected and quantitated by their 45ca2+-binding properties. in the first dimension, parvalbumins are purified by sieving through a gradient polyacrylamide gel and collected at the bottom of the electrophoresis tubes. the second dimension is a disc electrophoresis in the presence of 45ca2+. parvalbumins can thus be identified and quantitated by three criteria: low m ... | 1978 | 718978 |

| infectivity of fish rhabdoviruses for drosophila melanogaster. | two fish rhabdoviruses, spring viraemia of carp virus (svc) and pike fry rhabdovirus (pfr), have been shown to multiply in drosophila melanogaster. the other two fish rhabdoviruses, viral haemorrhagic septicaemia (vhs) and infectious hematopoietic necrosis (ihn), did not multiply under the conditions used. only those viruses which multiplied (i. e. svc, pfr) conferred a co2 sensitivity on the infected drosophila. no hereditary transmission of the fish viruses was detected. | 1975 | 811150 |
