[amino acid sequence of corticotropins from seiwhale (balaenoptera borealis) and pinwhale (balaenoptera physalus)].the corticotropins from two species of whales, e. g. seiwhale (balaenoptera borealis) and finwhale (balaenoptera physalus) were subjected to hydrolysis by trypsin, chymotrypsin and pepsin. the peptide fragments were separated by gel-filtration through sephadex and partition paper chromatography. the study of the amino acid sequence of the peptides obtained allowed to establish the primary structure of corticotropin from both species, which was found structurally identical to human corticotropin.1977201308
viruses and virus diseases of marine mammals.poxvirus and several serotypes of calicivirus cause recognizable disease in marine mammals. pox lesions in pinnipeds are raised and proliferative and are seen most frequently after confinement in captivity. in cetaceans, a poxvirus is associated with a much more benign and chronic lesion called a "tattoo." numerous caliciviruses of differing antigenic types have been isolated from vesicular lesions and aborted fetuses of northern fur seals and california sea lions as well as from clinically norm ...1979230170
prevalence of vesicular exanthema of swine antibodies among feral mammals associated with the southern california coastal zones.serum-neutralizing antibodies to both vesicular exanthema of swine virus (vesv) and san miguel sea lion virus (smsv) were found in a number of animal species having an association with the southern california coastal zones. california sea lions (zalophus californianus) had antibodies to 9 vesv types (a48, c52, d53, e54, f54, g55, i55, j56, and k56). fur seals (callorhinus ursinus) and elephant seal pups (mirounga angustirostris) were tested for antibodies to 6 vesv types and all were negative. c ...1978629463
studies on the blood clotting and fibrinolytic system in the plasma from a sei (baleen) whale.blood clotting and fibrinolytic systems were studied in the plasma of a sei whale (balaenoptera borealis). the sei whale belongs to the suborder baleen whales of the order cetacea. whale plasma had a greatly prolonged kaolin-activated partial thromboplastin time and was deficient in hageman factor (factor xii), fletcher factor (a plasma prekallikrein), and pta (factor xi). all other clotting factor activities were present in amounts comparable to that of normal human plasma. whale plasminogen wa ...1976967876
[primary structure of cyanogen bromide fragments of sei whale (balaenoptera borealis) pituitary somatotropin].5 fragments are isolated after the degradation of somatotropin from sei whale pituitary glands with cyanogen bromide: n-terminal 4-segmented; c-terminal 12-segmented with the internal disulfide bond; middle 25- and 30-segmented and a high molecular weight fragment following n-terminal tetrapeptide and bound with disulfide bond to 30-segmented fragment. complete amino acid sequence of three shortest cyanogen bromide fragments is deciphered and n- and c-terminal sequence is investigated in two lar ...19761022273
analysis of the c4 genes in baleen whales using a human cdna probe.we have used a human c4 cdna probe to investigate the complement component c4 gene in four members of the family balaenopteridae: fin whale (balaenoptera physalus), sei whale (b. borealis), minke whale (b. acutorostrata), and bryde's whale (b. edeni). restriction mapping of genomic dna from the first three species suggests the presence of only one locus in these species, and also shows that the c4 genes in the three species are very similar. we have used 14 restriction endonucleases to investiga ...19901975799
contribution of chemical 6-o-sulfation of the aminodeoxyhexose residues in whale heparin with high affinity for antithrombin iii to its anticoagulant properties.the tributylammonium salt of whale (balaenoptera borealis l.) intestinal heparin with high affinity for antithrombin iii, whose degrees of sulfate-substitution in d-glucosamine and l-iduronic acid residues are glcns 0.738, glcn6s 0.384, and idoa2s 0.510 mol, was reacted with 2.5, 5.0, or 10.0 mol of pyridine-sulfur trioxide/mol of available hydroxyl groups in n,n-dimethylformamide at -10 degrees c for 1 h. both chemical and nmr spectroscopic analyses revealed that an exclusive 6-o-sulfation of t ...19902341372
anticoagulant properties of heparin preparations from different animal sources with equivalent high affinity for antithrombin iii.three kinds of heparins from different animal sources--hog-intestinal heparin (167 usp units/mg), bovine-lung heparin (149 usp units/mg) and whale-intestinal heparin (balaenoptera borealis l., 174 usp units/mg)--were fractionated through an antithrombin iii-sepharose column and high-affinity (ha) subfractions (1.2-1.8 m nacl eluted fractions) were separated. these ha heparin specimens, which were confirmed to be equivalent in strength of binding to antithrombin iii, were compared with respect to ...19846725227
[neurotropic effect of hypophyseal somatotropin and its fragment].the effect of sei whale somatotropin and its biologically active fragment 77-107 (under conditions of microionophoresis) on the cortical, caudate nucleus and amygdala single neuron electrical activity of the rat brain as well as on the neuron sensitivity to noradrenaline was studied. the neurons, responded to somatotropin and its fragment inhibitory action, were revealed in all the brain regions examined. the majority of neurons did not react to noradrenaline, part of them responded to noradrena ...19836866954
[viruses of whales and dolphins].dna- and rna-genome viruses of whales and dolphins belong to families poxviridae, herpesviridae, adenoviridae, orthomyxoviridae, paramyxoviridae, togaviridae, picornaviridae. virological, serological and pathomorphological signs of infection have been registered in odontoceti (bottle-nosed dolphin, atlantic white-sided dolphin, striped dolphin, harbona porpoise, white-beaked dolphin, common dolphin, sperm whale, pilot whale, white whale) and musticeti (sei whale, fin whale, gray whale, and bowhe ...19969044706
evidence of brucella infection in marine mammals in the north atlantic ocean.between 1983 and 1996 a total of 1386 samples of serum were taken from four species of seal and three species of whale in the waters west of iceland, the area of pack-ice north-west of jan mayen, the northern coast of norway and the kola peninsula, the waters west of svalbard, and the barents sea; they were tested for the presence of anti-brucella antibodies with an indirect elisa (protein g conjugate). the positive sera were re-tested with classical brucellosis serological tests, such as the se ...199910378290
attempts at in vitro fertilization and culture of in vitro matured oocytes in sei ( balaenoptera borealis) and bryde's ( b. edeni) whales.the cumulus-oocyte-complexes (cocs) recovery rates with respect to reproductive status per sei (balaenoptera borealis) and bryde's (b. edeni) whales were determined in experiment 1. the number of cocs recovered ranged from 16.0 to 30.6 and from 6.7 to 26.8 per sei and bryde's whales, respectively. the effects of cocs grades and protein supplementation in embryo culture medium on development of in vitro fertilized (ivf) embryos were evaluated in sei and bryde's whales in experiment 2. the cocs we ...200918925980
production of sei whale (balaenoptera borealis) cloned embryos by inter- and intra-species somatic cell nuclear transfer.the objectives of this study were to choose an effective embryo reconstruction method and an effective post-activation agent for in vitro production of sei whale (balaenoptera borealis) interspecies somatic cell nuclear transfer (iscnt) embryos. moreover, trichostatin a (tsa) treatment of whale iscnt embryos was performed to improve the in vitro embryo development. in experiment 1, the fusion rate was significantly higher (88.1%) in embryos reconstructed using the intracytoplasmic cell injection ...201019893277
production of cloned sei whale (balaenoptera borealis) embryos by interspecies somatic cell nuclear transfer using enucleated pig oocytes.in this study, we examined the feasibility of using subzonal cell injection with electrofusion for interspecies somatic cell nuclear transfer (iscnt) to produce sei whale embryos and to improve their developmental capacity by investigating the effect of osmolarity and macromolecules in the culture medium on the in vitro developmental capacity. hybrid embryos produced by the electrofusion of fetal whale fibroblasts with enucleated porcine oocytes were cultured in modified porcine zygote medium-3 ...200919934592
a generalized baleen whale call detection and classification system.passive acoustic monitoring allows the assessment of marine mammal occurrence and distribution at greater temporal and spatial scales than is now possible with traditional visual surveys. however, the large volume of acoustic data and the lengthy and laborious task of manually analyzing these data have hindered broad application of this technique. to overcome these limitations, a generalized automated detection and classification system (dcs) was developed to efficiently and accurately identify ...201121568392

endoparasite survey of free-swimming baleen whales (balaenoptera musculus, b. physalus, b. borealis) and sperm whales (physeter macrocephalus) using non/minimally invasive methods.a number of parasitic diseases have gained importance as neozoan opportunistic infections in the marine environment. here, we report on the gastrointestinal endoparasite fauna of three baleen whale species and one toothed whale: blue (balaenoptera musculus), fin (balaenoptera physalus), and sei whales (balaenoptera borealis) and sperm whales (physeter macrocephalus) from the azores islands, portugal. in total, 17 individual whale fecal samples [n = 10 (b. physalus); n = 4 (p. macrocephalus); n = ...201626593736
marine mammal strandings in the new caledonia region, southwest pacific.four hundred twenty three marine mammals, in 72 stranding events, were recorded between 1877 and 2005 in new caledonia, the loyalty islands, and vanuatu in the southwest pacific. sixteen species were represented in this count, including: minke whale, balaenoptera acutorostrata (1 single stranding), sei whale, b. borealis (1 single stranding), blue whale, b. musculus (1 single stranding), humpback whale, megaptera novaeangliae (2 single strandings), giant sperm whale, physeter macrocephalus (18 s ...200616644500
long-term and large-scale epidemiology of brucella infection in baleen whales and sperm whales in the western north pacific and antarctic oceans.in a long-term, large-scale serologic study in the western north pacific ocean, anti-brucella antibodies were detected in common minke whales (balaenoptera acutorostrata) in the 1994-2010 offshore surveys (21%, 285/1353) and in the 2006-2010 japanese coastal surveys (20%, 86/436), in bryde's whales (b. edeni brydei) in the 2000-2010 offshore surveys (9%, 49/542), in sei whales (b. borealis) in the 2002-2010 offshore surveys (5%, 40/788) and in sperm whales (physeter macrocephalus) in the 2000-20 ...201627320816
extensively remodeled, fractured cetacean tympanic bullae show that whales can survive traumatic injury to the ears.underwater human activities and anthropogenic noise in our oceans may be a major source of habitat degradation for marine life. this issue was highlighted by the opening of the united states eastern seaboard for seismic oil and gas exploration in 2014, which generated massive media coverage and widespread concern that seismic surveys could kill or deafen whales. we discovered 11 new specimens of fractured and healed cetacean ear bones, out of a survey of 2127 specimens housed in museum collectio ...201626391309
a protein a/g indirect enzyme-linked immunosorbent assay for the detection of anti-brucella antibodies in arctic wildlife.a species-independent indirect enzyme-linked immunosorbent assay (ielisa) based on chimeric protein a/g was established for the detection of anti-brucella antibodies in arctic wildlife species and compared to previously established brucellosis serological tests for hooded seals (cystophora cristata), minke whales (balaenoptera acutorostrata), sei whales (balaenoptera borealis), fin whales (balaenoptera physalus), and polar bears (ursus maritimus), as well as bacteriology results for reindeer and ...201323572454
cdna-derived amino acid sequences of myoglobins from nine species of whales and dolphins.we determined the myoglobin (mb) cdna sequences of nine cetaceans, of which six are the first reports of mb sequences: sei whale (balaenoptera borealis), bryde's whale (balaenoptera edeni), pygmy sperm whale (kogia breviceps), stejneger's beaked whale (mesoplodon stejnegeri), longman's beaked whale (indopacetus pacificus), and melon-headed whale (peponocephala electra), and three confirm the previously determined chemical amino acid sequences: sperm whale (physeter macrocephalus), common minke w ...200616962803
bones as biofuel: a review of whale bone composition with implications for deep-sea biology and palaeoanthropology.whales are unique among vertebrates because of the enormous oil reserves held in their soft tissue and bone. these 'biofuel' stores have been used by humans from prehistoric times to more recent industrial-scale whaling. deep-sea biologists have now discovered that the oily bones of dead whales on the seabed are also used by specialist and generalist scavenging communities, including many unique organisms recently described as new to science. in the context of both cetacean and deep-sea inverteb ...201120702457
identifying the "demon whale-biter": patterns of scarring on large whales attributed to a cookie-cutter shark isistius sp.the presence of crater-like wounds on cetaceans and other large marine vertebrates and invertebrates has been attributed to various organisms. we review the evidence for the identity of the biting agent responsible for crater wounds on large whales, using data collected from sei (balaenoptera borealis), fin (b. physalus), inshore and offshore bryde's (b. brydeii sp) and sperm whales (physeter macrocephalus) examined at the donkergat whaling station, saldanha bay, south africa between march and o ...201627055057
stable isotope ratios and mercury levels in red meat products from baleen whales sold in japanese markets.we analyzed the δ(13)c, δ(15)n and δ(18)o values and hg concentration in red meat products originating from the predominant types sold in japan for human consumption: two populations of common minke (j- and o-types), bryde's and sei whales in the western north pacific ocean, and fin and antarctic minke whales in the southern ocean. the order of the trophic positions, evaluated by δ(15)n values and hg concentrations, coincided with their known feeding habits: common minke (j-type)=common minke (o ...201222364843
chemical characterization of the oligosaccharides in bryde's whale (balaenoptera edeni) and sei whale (balaenoptera borealis lesson) milk.samples of milk from a bryde's whale and a sei whale contained 2.7 g/100 ml and 1.7 g/100 ml of hexose, respectively. both contained lactose as the dominant saccharide along with small amounts of neu5ac(alpha2-3)gal(beta1-4)glc (3'-n-acetylneuraminyllactose), neu5ac(alpha2-6)gal(beta1-4)glc (6'-n-acetylneuraminyllactose) and neu5ac(alpha2-6)gal(beta1-4)glcnac(beta1-3)gal(beta1-4)glc (lst c). the dominance of lactose in the carbohydrate of these milks is similar to that of minke whale milk and bo ...200717113803
complete amino acid sequence of the myoglobin from the pacific sei whale, balaenoptera borealis.the complete amino acid sequence of the major component myoglobin from pacific sei whale, balaenoptera borealis, was determined by specific cleavage of the protein to obtain large peptides which are readily degraded by the automatic sequencer. the acetimidated apomyoglobin was selectively cleaved at its two methionyl residues with cyanogen bromide and at its three arginyl residues by trypsin. from the sequence analysis of four of these peptides and the apomyoglobin, over 75% of the covalent stru ...1979454658
baleen wear reveals intraoral water flow patterns of mysticete filter feeding.a survey of macroscopic and microscopic wear patterns in the baleen of eight whale species (cetacea: mysticeti) discloses structural, functional, and life history properties of this neomorphic keratinous tissue, including evidence of intraoral water flow patterns involved in filter feeding. all baleen demonstrates wear, particularly on its medial and ventral edges, as flat outer layers of cortical keratin erode to reveal horn tubes, also of keratin, which emerge as hair-like fringes. this study ...201626825852
omura's whales (balaenoptera omurai) off northwest madagascar: ecology, behaviour and conservation needs.the omura's whale (balaenoptera omurai) was described as a new species in 2003 and then soon after as an ancient lineage basal to a bryde's/sei whale clade. currently known only from whaling and stranding specimens primarily from the western pacific and eastern indian oceans, there exist no confirmed field observations or ecological/behavioural data. here we present, to our knowledge, the first genetically confirmed documentation of living omura's whales including descriptions of basic ecology a ...201526587244
source level estimates for sei whale (balaenoptera borealis) vocalizations off the azores.sei whale calls have been documented on very few occasions and never in the azores archipelago, an area transited by this species during their migration to northern latitudes in spring and early summer. using a combination of video range tracking (vrt) and acoustic methods, vocalizations are described from an encounter with two sei whales in april 2012 off pico island, azores. recordings analyzed post-survey revealed 53 low frequency downsweep calls with average maximum frequencies of 100 hz [st ...201526520318
discrimination of frequency-modulated baleen whale downsweep calls with overlapping frequencies.automatic classification of fin, sei, and blue whale frequency modulated downsweeps has been a challenging task for bioacousticians. these calls overlap in frequency range and have similar time durations. the traditional spectrogram methodology, the short time fourier transform, tends to be ineffective because of the large temporal ambiguities needed to achieve the necessary frequency resolution to study the fine time-frequency (tf) structures. spectrograms generated with the pseudo wigner-ville ...201526093394
low-frequency vocalizations of sei whales (balaenoptera borealis) in the southern ocean.simultaneous sightings and acoustic detections of sei whales (balaenoptera borealis) are scarce, and there are few published data describing their vocalizations. analysis of recordings from directional frequency analysis and recording sonobuoys in the presence of sei whales in the southern ocean in march 2013 identified both downsweep and upsweep calls. sound frequencies within all calls were between 34 and 87 hz with an average call duration of 1.1 s. these very low-frequency sounds share chara ...201425480092
juvenile morphology in baleen whale phylogeny.phylogenetic reconstructions are sensitive to the influence of ontogeny on morphology. here, we use foetal/neonatal specimens of known species of living baleen whales (cetacea: mysticeti) to show how juvenile morphology of extant species affects phylogenetic placement of the species. in one clade (sei whale, balaenopteridae), the juvenile is distant from the usual phylogenetic position of adults, but in the other clade (pygmy right whale, cetotheriidae), the juvenile is close to the adult. diffe ...201425081817
long distance passive localization of vocalizing sei whales using an acoustic normal mode approach.during a 2 day period in mid-september 2006, more than 200, unconfirmed but identifiable, sei whale (balaenoptera borealis) calls were collected as incidental data during a multidisciplinary oceanography and acoustics experiment on the shelf off new jersey. using a combined vertical and horizontal acoustic receiving array, sei whale movements were tracked over long distances (up to tens of kilometers) using a normal mode back propagation technique. this approach uses low-frequency, broadband pas ...201222352607
low frequency vocalizations attributed to sei whales (balaenoptera borealis).low frequency (<100 hz) downsweep vocalizations were repeatedly recorded from ocean gliders east of cape cod, ma in may 2005. to identify the species responsible for this call, arrays of acoustic recorders were deployed in this same area during 2006 and 2007. 70 h of collocated visual observations at the center of each array were used to compare the localized occurrence of this call to the occurrence of three baleen whale species: right, humpback, and sei whales. the low frequency call was signi ...200818681619
sei whale sounds recorded in the antarctic.sei whales are the least well known acoustically of all the rorquals, with only two brief descriptions of their calls previously reported. recordings of low-frequency tonal and frequency swept calls were made near a group of four or five sei whales in waters west of the antarctic peninsula on 19 february 2003. these whales also produced broadband sounds which can be described as growls or whooshes. many of the tonal and frequency swept calls (30 out of 68) consist of multiple parts with a freque ...200516419837
genetic characteristics of western north pacific sei whales, balaenoptera borealis, as revealed by microsatellites.genetic characteristics of sei whales, balaenoptera borealis, inhabiting the western north pacific were analyzed at 17 microsatellite loci in a total of 89 whales obtained from the area between 37 degrees n-45 degrees n and 147 degrees e-166 degrees e in 2002 (n=39) and 2003 (n=50). all the loci analyzed were polymorphic over the samples, some of the loci had more than 10 alleles, indicating a high level of genetic variation within samples. no significant deviation from the expected hardy-weinbe ...200816328098
the separation of whale myoglobins with two-dimensional electrophoresis.five myoglobins (sperm whale, sei whale, hubbs' beaked whale, pilot whale, and amazon river dolphin) were examined using two-dimensional electrophoresis. previous reports indicated that none of these proteins could be separated by using denaturing (in the presence of 8-9 m urea) isoelectric focusing. this result is confirmed in the present study. however, all the proteins could be separated by using denaturing nonequilibrium ph-gradient electrophoresis in the first dimension. additionally, all t ...19883242499
inhibitory activities for thrombin and factor xa of whale heparin: comparative studies on two preparations from different species.whale intestinal heparin preparations from balaenoptera physalus l. (bp) and balaenoptera borealis l. (bb) were fractionated by affinity chromatography on a column of antithrombin iii (at)-sepharose 4b. the yields of high-affinity fractions for at (ha) from bp and bb were 86.8 and 13.3%, respectively, in total. the inhibitory activities for thrombin of bp and bb and their ha and those for factor xa of the latter were compared in the presence of at. the results indicated that the inhibitory activ ...19863775773
conservation of highly repetitive dna in cetaceans.it is controversial whether odontocetes (toothed whales) and mysticetes (whalebone whales) have a common ancestry. cetacean karyological uniformity, which is unique among mammalian orders, suggests a monophyletic origin; however, several anatomical authorities have maintained that odontocetes and mysticetes are diphyletic. we investigated the issue using southern blot hybridization. two labelled restriction fragment probes from the dna of the sei whale (a mysticete) were hybridized to restricted ...19846325102
lipids of the antarctic sei whale, balaenoptera borealis.the blubber, liver, and muscle of the antarctic sei whale were analyzed for total lipid content, composition of lipid by classes and positional distribution of fatty acids in individual lipids. the major glycerolipids (triglycerides, phosphatidylcholine, and phosphatidylethanolamine) were fractionated by silver nitrate thin layer chromatography. the phospholipid fractions were analyzed for fatty acid positional distribution. the whale stomach contained almost exclusively the amphipod parathemist ...1978628313
on urea formation in marine mammals.ornithine carbamoyltransferase (ec 2.1.3.3) has been determined in homogenates of liver of the sei whale (balaenoptera borealis), the bottle-nose dolphin (porpoise) (tursiops truncatus) and california sea lion (zalophus californianus). these marine mammals show levels of this ornithine-urea cycle enzyme which are typical of terrestrial mammals.1977862778
