| reactivity and ionization constants of the lysine residues in apovitellenin i of emu egg yolk low-density lipoprotein by competitive labelling. | competitive labelling with[14c]acetic anhydride over a range of ph values has been used to explore the surface topography of the apovitellenin i moiety in emu egg yolk low-density lipoprotein. the reaction of the lysine xi-amino groups with acetic anhydride has been related to ph in a set of titration curves; from these, the reactivities relative to alanine and the ionization constants of all but the amino terminal lysines have been determined. all lysines have near normal pka values around 10, ... | 1975 | 5069 |
| immunoabsorption of membrane-specific antibodies for determination of exposed and hidden proteins in human erythrocyte membranes. | human erythrocyte membrane proteins solubilized with the non-ionic detergent berol emu-043 have been characterized by crossed immunoelectrophoresis with rabbit antibodies raised against the membrane material. three out of sixteen membrane-specific immunoprecipitates disappeared when the antisera were first absorbed with intact erythrocytes. this finding indicates that three antigens are exposed on the outside of the erythrocyte membrane. one of these antigens showed acetylcholinesterase activity ... | 1975 | 49198 |
| quantitative immunoelectrophoresis of proteins in human erythrocyte membranes. analysis of protein bands obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. | 1. we have defined conditions that permit quantitative immunoelectrophoresis in agarose gels of dodecyl sulfate-solubilized erythrocyte membrane proteins. 2. using human serum albumin, transferrin, mn-glycoprotein (glycophorin) and crude spectrin as test proteins, we found that accurate analyses are possible if samples and gels are 1% in non-ionic detergent (berol emu-043) or triton x-100) and if no more than 100 nmol free dodecyl sulfate is applied per sample. 3. dodecyl sulfate treated membran ... | 1975 | 52375 |
| urinary hydroxyproline excretion in carcinoma of the prostate. a comparison of 4 different modes of assessment and its role as a marker. | urinary hydroxyproline (hp) excretion has been estimated without prior dietary restriction in 33 patients with carcinoma of the prostate and expressed as either 24-h hp output or as the hydroxyproline/creatinine (hp/cr) ratio in 24-h urine sample, an early morning urine sample or a spot urine sample. the early morning urine hydroxyproline/creatinine ratio (emu hp/cr) appears to be the most accurate and avoids the disadvantages of formal dietary restriction and prolonged urine collection. the res ... | 1979 | 534843 |
| lipid-protein globules of avian egg yolk. isolation and properties of globules stable in concentrated sodium chloride solution. | a new type of globular particle, the 'insoluble yolk globule', was isolated from the egg yolk of three avian species (hen, duck, and emu) by centrifugation or gel-filtration chromatography. these globules are stable in nacl and urea solutions at concentrations that dissolve or disrupt other constituents of yolk, the isolated globules are about 1% of the dry yolk of hen's and duck's eggs but about 8% emu's-egg yolk. most of these globules are less than 2 micrometer in diameter. electron micrograp ... | 1977 | 563717 |

| primary structure of apovitellenin i from hen egg yolk and its comparison with emu apovitellenin i. | the amino acid sequence of apovitellenin i from hen egg yolk has been determined using both automatic and manual procedures; it comprises 82 residues. hen apovitellenin shows considerable homology with emu apovitellenin i which contains 84 residues. besides two deletions in the sequence, the hen protein differs in 28 positions from the emu protein; 26 of these positions may have arisen from single base changes. the changes are largely conservative ones, which suggest that the structure and funct ... | 1976 | 988817 |
| chemoreceptors in the paleopulmonic lung of the emu: discharge patterns during cyclic ventilation. | 1976 | 1013516 | |
| response to co2 of intrapulmonary chemoreceptors in the emu. | we studied discharge frequencies of 12 intrapulmonary chemoreceptors in the paleopulmonic lung of an emu (dromiceius novaechollandiae) during unidirectional, artificial ventilation when step changes and static co2 concentrations were given. discharge frequency in afferent neurons from the receptors increased as intrapulmonary co2 decreased. the response of the receptors to various static intrapulmonary co2 concentrations was similar to that previously demonstrated for the duck and chicken. the m ... | 1976 | 1019429 |
| studies on the apoproteins of the major lipoprotein of the yolk of hen's eggs. i. isolation and properties of the low-molecular-weight apoproteins. | in a continuing study of protein-lipid interactions in egg yolk, the total apoprotein mixture (i.e. the 'apovitellenins') from the high-lipid, low-density lipoprotein (density 0.97 g/ml) of the yolk from hen's eggs has been isolated in a soluble form. by gel-filtration chromatography in 6m urea the mixture has been separated into several fractions from which three new low-molecular-weight proteins (i, ia, and ii), making up about 30% of the total, have been isolated. the most plentiful of these ... | 1975 | 1167127 |
| urinary protein/creatinine index in follow up of patients with wilms' tumour after nephrectomy. | the protein/creatinine index (p/c) was determined in early morning urine (emu) samples from available patients with wilms' tumour who had had a nephrectomy and whose diagnosis had been made between january 1970 and december 1989. clinical details were obtained by case note review. results were obtained from 36 boys and 40 girls. the mean interval between nephrectomy and measurement of the emup/c was 9.0 years (2-23). eleven patients had a emup/c greater than 20 mg/mmol (normal range less than 20 ... | 1992 | 1336953 |
| estrone 3-glucuronide chemiluminescence immunoassay (lia) and 17beta estradiol radioimmunoassay (ria) in the monitoring of superovulation for in vitro fertilization (ivf): correlation with follicular parameters and oocyte maturity. | many works in the literature of the last years had reported that urinary approach to superovulation study is a suitable method to evaluate ovarian response to pharmacological stimulation. before applying urinary determination of hormonal levels with a chemiluminescence immuno assay (lia) method in early morning urine (emu) samples, we had studied the correlation of ria-lia procedures with reference to follicular volumes at hcg day and to recovered oocyte maturity; in fact follicular growth and o ... | 2013 | 1338258 |
| eastern equine encephalitis in a flock of emus (dromaius novaehollandiae). | eastern equine encephalitis (eee) was diagnosed in a flock of emus in southeastern louisiana. the outbreak involved juvenile and adult breeders ranging in age from 20 to 36 months, with an attack rate of 76% and a case fatality rate of 87%. the diagnosis was confirmed by isolation and characterization of the viral agent, and by detection of eee antibody in two recovered emus. high mortality was preceded by marked depression, hemorrhagic diarrhea, and emesis of blood-stained ingesta. on postmorte ... | 1992 | 1417619 |
| assessment of potential doses at the maralinga and emu test sites. | an assessment has been undertaken of potential doses to future aboriginal inhabitants of the maralinga and emu areas of south australia, where nuclear weapons tests in the 1950s and 1960s have resulted in residual radioactive contamination. radioactive material due to this program of tests and other experiments is still detectable several tens of kilometers from some of the test sites. continued occupancy by individuals following an aboriginal lifestyle could give rise to annual effective dose e ... | 1992 | 1428882 |
| inhalation doses for aboriginal people reoccupying former nuclear weapons testing ranges in south australia. | the australian government plans to rehabilitate the former nuclear weapons testing ranges at maralinga and emu in south australia and to allow access to the areas for the pitjantjatjara (aboriginal) people who are the traditional owners of the land. the major radiological hazard posed by reoccupation of the ranges arises from inhalation of residual plutonium. the committed effective dose that these people might receive from inhalation on reoccupation of the lands is computed for a range of sites ... | 1992 | 1428883 |
| reference serum biochemical values for emus and ostriches. | reference serum biochemical values were determined in blood samples from 15 male, 18 female, and 4 unsexed emus (dromaius novaehollandiae) 1 to 48 months old. serum biochemical values also were obtained for 19 male, 26 female, and 4 unsexed ostriches (struthio camelus) 1 to 60 months old. parametric (mean +/- 2 sd) and non-parametric (fifth to 95th percentile) reference ranges and linear trends as influenced by age were determined for enzyme activities and concentrations of glucose, inorganic ph ... | 1992 | 1456516 |
| down-regulation of c-myc antigen expression in lymphocytes of emu-c-myc transgenic mice treated with anti-c-myc dna methylphosphonates. | in transgenic mice bearing a murine immunoglobulin enhancer/c-myc fusion transgene (emu-myc), it was found that antisense dna methylphosphonates targeted against c-myc mrna inhibited production of c-myc protein in peripheral lymphocytes. the decrease in protein was measured 3-4 h after i.v. administration of a 300-nmol dose. c-myc was detected by immunofluorescence of fixed cells stained with an anti-c-myc antiserum. in addition, dna methylphosphonates did not induce acute toxicity following i.v ... | 1992 | 1458461 |
| urinary tuberculosis: experience of a teaching hospital in syria. | this study was designed to show our experience of urinary tuberculosis in one of the large teaching hospitals in syria. it was a prospective study involving 48 patients (29 males and 19 females) with confirmed tuberculous lesions in the urinary tract. the study period was between 1982-1987. the presenting symptoms were protean, and there were often delays between onset of symptoms and eventual diagnosis. the highest age incidence was in the second and fourth decades. beside the suggestive clinic ... | 1992 | 1459824 |
| strain dependency of cell-type specificity and onset of lymphoma development in emu-myc transgenic mice. | c-myc is a nuclear proto-oncogene that, when activated, induces malignancies in a variety of tissues. most murine plasmacytomas and human burkitt's lymphomas have been shown to carry a chromosomal translocation involving c-myc and immunoglobulin genes. to study genetic or epigenetic factors that affect myc-induced lymphoid cell tumors, we previously introduced the emu-myc delta gene lacking its own promoter and first exon into two inbred strains of mice, c57bl/6 and c3h/hej. we observed three ch ... | 1992 | 1582889 |
| immunochemical tests of potential fertility. | there are many methods of determining the physiological basis of cyclical periods of potential fertility: calculations, sensations, or physical or chemical biosensors. this article reviews the development of self-tests of potential fertility using immunoassay of hormone metabolites in urine. indices of potential fertility in urine are the concentration of principal metabolites of steroid hormones and luteinizing hormone (lf). the ovaries produce an estimated 50-800 mcg of estradiol/day, the most ... | 1992 | 1633952 |
| transient expression of the coat protein of sugarcane mosaic virus in sugarcane protoplasts and expression in escherichia coli. | the coat protein (cp) of strain sc of sugarcane mosaic virus (scmv-sc) was expressed transiently in sugarcane protoplasts after electroporation with one of two plasmids encoding the cp gene. the cp gene was fused with either the cauliflower mosaic virus 35s promoter or the synthetic monocotyledon promoter "emu". the coat protein gene was also inducibly expressed in escherichia coli when fused to the trc promoter. the protein expressed in both systems had the same electrophoretic mobility and ant ... | 1992 | 1642548 |
| evaluation of endocrine parameters in clinical trials with beta-hcg vaccine. | this report presents data on various endocrine parameters with respect to pituitary-ovarian axis in-depth in control vs 18 subjects immunized with three beta-hcg based vaccine formulations. hormonal parameters such as tsh, prl, acth, progesterone, cortisol, t3 and t4 were measured by ria in sera in control pre-vaccine cycles as well as at 3, 6, and 12 months after primary vaccine immunization. in 6 women urinary e1g, pdg, lh and fsh were measured by elisa/ria tests on early morning urine (emu) s ... | 1991 | 1706244 |
| activation of immunoglobulin control elements in transgenic mice. | to assess the role interleukins and mitogens play in regulating immunoglobulin (ig) gene expression via the ig enhancer and promoter, transgenic mice carrying two different ig gene regulatory regions were generated. one, emukcat, contains the ig heavy chain enhancer (emu) and the kappa light chain promoter driving the chloramphenicol acetyltransferase (cat) gene. in the other, delta emukcat, cat is under the control of the kappa promoter alone. emu and kappa relative activity were assessed by ca ... | 1992 | 1729170 |
| sequence conservation in avian cr1: an interspersed repetitive dna family evolving under functional constraints. | cr1 is a short interspersed repetitive dna element originally identified in the domestic chicken (gallus gallus). however, unlike virtually all other such sequences described to date, cr1 is not confined to one or a few closely related species. it is probably a ubiquitous component of the avian genome, having been detected in representatives of nine orders encompassing a wide spectrum of the class aves. this identification was made possible by using the polymerase chain reaction (pcr), which rev ... | 1991 | 1829530 |
| spermatozoa and relationships in palaeognath birds. | in this paper the authors describe the ultrastructure of the mature spermatozoon and the spermatid in struthio camelus and dromaius novaehollandiae. the first species is characterized by a rod-like perforatorium within an endonuclear canal in the anterior third of the nucleus, while the second is characterized by an extremely reduced completely extranuclear perforatorium. other differences are in the sperm dimensions, the number of mitochondria and the length of the axonemal accessory fibers. co ... | 1991 | 1912945 |
| selection of the t-cell repertoire in transgenic mice expressing a transplantation antigen in distinct thymus subsets. | transgenic mice that expressed a transplantation antigen, h-2kb, in an unusual tissue distribution have been developed. gene-regulatory elements from the immunoglobulin heavy-chain locus (emu enhancer and heavy chain promoter) were linked to the class i kb gene and the construct microinjected into fertilized mouse eggs of a different haplotype. it was expected that such gene-regulatory elements would direct expression of the foreign class i molecules only to b and t lymphocytes. however, express ... | 1990 | 1979441 |
| carcinogen-induced lymphomagenesis in pim-1 transgenic mice: dose dependence and involvement of myc and ras. | transgenic mice overexpressing the pim-1 oncogene in their lymphoid compartments are predisposed to t-cell lymphomagenesis but only to the extent that approximately 10% of the transgenic mice develop lymphomas within 34 weeks after birth. recently, we have shown that lymphomagenesis in pim-1 transgenic mice can be accelerated by infecting pim-1 transgenic mice with murine leukemia viruses or by treating the mice with a relatively low dose of 60 mg of the carcinogen n-ethyl-n-nitrosourea (enu) pe ... | 1991 | 1988138 |
| the epidermal melanin unit in the pathophysiology of malignant melanoma. | the epidermal melanin unit (emu) denotes the symbiotic relationship between a melanocyte and a pool of associated keratinocytes. we propose to show that alterations in the biology of the emu are the main determinant of the different patterns of intraepidermal growth of melanocytes in lentigo maligna melanoma (lmm) and superficial spreading melanoma (ssm). they also appear to affect the biosynthesis of melanin and melanosomes during malignant transformation. findings in histochemical studies with ... | 1991 | 2029092 |
| restricted utilization of vh and dh genes in leukemic rabbit b cells. | polyclonal b cell leukemias have been generated in 17- to 20-day old emu-myc transgenic rabbits. to analyze the repertoire of vh genes utilized in early b cells, eight vdj genes were cloned from these leukemic cells. the nucleotide sequences of these genes indicated that seven of the eight vdj genes encoded prototype vha1, vha2 or vha3 allotypes. the two vdj genes encoding vha1 molecules had vh segments with identical nucleotide sequences; similarly, the vh segments of the four vdj genes encodin ... | 1990 | 2107085 |
| igh enhancer deregulated expression of l-myc: abnormal t lymphocyte development and t cell lymphomagenesis. | transgenic constructs containing the murine l-myc gene under the control of the immunoglobulin transcriptional enhancer element (emu) are expressed at unexpectedly high levels in thymocytes and proliferating t cells compared with cells from bone marrow and proliferating b cells. in contrast, double transgenic animals bearing constructs containing the l- and n-myc genes similarly linked to the emu element maintain preferential l-myc expression in t cells but express the n-myc transgene preferenti ... | 1990 | 2120050 |
| partial amino acid sequence of osteocalcin from an extinct species of ratite bird. | osteocalcin the major gamma carboxyglutamic acid containing protein of vertebrate bone has been purified from the bones of a specimen of pachyornis elephantopus, a species of the extinct class of new zealand ratite birds, the moas. the sequence of the n-terminal region of moa osteocalcin was determined using gas phase n-terminal sequencing. the n-terminal sequences of the ostrich and rhea osteocalcins were also determined. alignment of the n-terminal sequence of osteocalcin from the extinct moa ... | 1990 | 2222494 |
| abelson murine leukemia virus transforms preneoplastic emu-myc transgene-carrying cells of the b-lymphocyte lineage into plasmablastic tumors. | e mu-myc transgenic mice were back-crossed to balb/c mice up to back-cross generation 3. the offspring that included transgene-carrying and -negative mice in approximately equal proportions were randomly divided into 2 groups. thirty-four mice (group i) were treated with pristane, followed by a-mulv, and 40 (group ii) were injected with a-mulv alone. altogether, 16 lymphoid tumors developed in group i and 17 in group ii. nine of the tumors in group i and 4 in group ii appeared as ascitic tumors. ... | 1990 | 2228313 |
| rearrangement of vha1-encoding ig gene segment to the a2 chromosome in an a1/a2 heterozygous rabbit. evidence for trans recombination. | vdj genes were cloned from leukemic b cells of an a1/a2 heterozygous emu-cmyc transgenic rabbit. restriction mapping and nucleotide sequence analysis indicated that one clone, 5c3, had a vha1-encoding gene segment functionally rearranged to a jh gene segment from the a2 chromosome. this vdj gene may be the result of a trans recombination between a vh gene on the a1 chromosome and a jh gene segment on the a2 chromosome or, it may be the result of a cis recombination if the a2 chromosome contains ... | 1990 | 2307849 |
| urinary hormonal profile during the first cycle of low-dose oral contraceptive pills in women. | ovarian function was studied in ten normal fertile women before and during the first cycle on a low-dose micropill containing 30 mcg ethinyl estradiol and 150 mcg l-norgestrel. in a control cycle and the first treatment cycle, steroid metabolites estrone-3-glucuronide (e1-3g) and pregnanediol-3 alpha-glucuronide (pd-3g) were measured in daily early morning urine (emu) samples. also, luteinizing hormone (lh) was estimated during the expected periovulatory period. during the first cycle of micropi ... | 1990 | 2387153 |
| use of superparamagnetic particles for isolation of cells. | this report describes the preparation and characterization of synthetic ferritin-like particles produced by precipitation of magnetite from a mixture of ferrous and ferric ions in the presence of dextran. the 3-nm diameter particles, containing magnetite cores surrounded by chemisorbed dextran, had a magnetization of 46.7 emu/g of iron with mössbauer quadrupole splitting of 2 delta = 0.76 mm/s. the application of these particles as a laboratory reagent for isolation of legionella from other wate ... | 1986 | 2418094 |
| hemopoietic lineage switch: v-raf oncogene converts emu-myc transgenic b cells into macrophages. | hemopoietic lineage commitment can be breached by concomitant expression of the c-myc and v-raf oncogenes. switching to the myeloid lineage occurred frequently when b lineage cells, from either lymphomas or preleukemia bone marrow cells of emu-myc transgenic mice, were infected with a retrovirus bearing v-raf. cloned pre-b and b cell lines changed into either mature or immature macrophages as assessed by morphology, adherence, phagocytic activity, surface markers, and lysozyme production, but re ... | 1988 | 2454746 |
| acceleration of b-lymphoid tumorigenesis in e mu-myc transgenic mice by v-h-ras and v-raf but not v-abl. | emu-myc transgenic mice constitutively express the c-myc oncogene from before birth, but their inexorable development of b-lymphoid tumors appears to require rare spontaneous alterations within b-lineage cells. to determine whether other oncogenes can cooperate with myc to induce b-lymphoid transformation, we infected neonatal emu-myc mice and normal littermates with helper-free retroviruses bearing the v-h-ras, v-raf, or v-abl oncogene. the v-h-ras and the v-raf oncogene dramatically accelerate ... | 1989 | 2549487 |
| the lung of the emu, dromaius novaehollandiae: a microscopic and morphometric study. | qualitative and quantitative characteristics suggest that the lung of the emu is poorly adapted for gas exchange when compared with that of other birds. the granular epithelial cells extend over the air capillaries, and the squamous epithelial cells have microvilli indicating a poor differentiation of the epithelium of the exchange tissue. the surface area of the blood-gas tissue barrier per unit body mass was only 5.4 cm2/g, the volume of the pulmonary capillary blood per unit body mass was onl ... | 1989 | 2606782 |

| lymphomagenesis in emu-myc transgenic mice does not require transgene rearrangement or mutation of myc exon 1. | in most human burkitt's lymphomas, translocation of the myc oncogene to an immunoglobulin locus is associated with loss of myc exon 1 or with mutations near its 3' border, a region where myc transcription is attenuated and translation of a larger myc polypeptide initiates. emu-myc transgenic mice, which bear the three myc exons coupled to an immunoglobulin enhancer, provide a model for the development of such lymphomas, because their lymphomagenesis appears to require events other than expressio ... | 1989 | 2699507 |
| occurrence of magnetic material in teleosts. | fishes representing the main groups of teleosts have been investigated for magnetic material by susceptibility measurements. all the investigated species contain magnetic material. bone samples from the skull and the vertebral column contain magnetic particles which yield a saturation magnetization in the range 10(-4) emu g-1 to 10(-3) emu g-1 in a sample. the localization of the magnetization is diffuse within the tissues connected to the bone. there are no significant differences between the a ... | 1987 | 2881648 |
| properties of the liquid crystals of some biopolymers. | nematic liquid-crystalline solutions of polypeptides such as pblg and pelg orient in the direction of a very low static electric field as if the polypeptide molecules were a collection of rod-like molecular clusters having a huge, permanent electric dipole moment. this dipole moment originates from fluctuation of the distribution of polymer helices in both directions of the rod-like molecular cluster with roughly equal likelihood. the molecular cluster of pblg is estimated to be composed of some ... | 1988 | 3077236 |
| specific guidance of motor axons to duplicated muscles in the developing amniote limb. | the effect of alteration of limb pattern upon motor axon guidance has been investigated in chick embryos. following grafting of the zone of polarizing activity (zpa) into the anterior margin of the early limb bud, limbs develop with forearms duplicated about the anteroposterior axis. the position of motoneurones innervating the duplicated posterior forearm extensor emu was mapped by retrograde transport of horse radish peroxidase (hrp). the motor pool labelled from injection into the anteriorly ... | 1988 | 3197635 |
| simplified quantification of urinary protein excretion in children. | the protein/creatinine ratio (up/uc) measured in 71 early morning urine samples (emu) correlated closely with timed overnight urine (onu) protein excretion rates (r = 0.96). the relationship was linear throughout the entire range of normal and abnormal protein excretion, an onu rate of 1 mg/h/m2 body surface area being proportional to an emu up/uc of 5 mg/mmol. using the coomassie blue dye-binding method the upper limit of up/uc in 377 apparently healthy children and adolescents aged 3-19 years ... | 1988 | 3214967 |

| the amino acid sequence of emu osteocalcin: gas phase sequencing of gla-containing proteins. | osteocalcin (oc), the major gamma carboxyglutamic acid (gla)-containing protein of vertebrate bone, has been isolated from bones of the emu (dromaius novaehollandae) and the primary structure determined by a combination of gas phase n-terminal sequencing of the intact molecule and a proteolytic fragment, and carboxypeptidase y c-terminal sequencing. gla residues were located by counting tritium radioactivity in fractions from the n-terminal sequencing of the tritiated/thermally decarboxylated mo ... | 1987 | 3501719 |
| [iatrogenic inguinal injury of the spermatic cord from a treatment and forensic viewpoint]. | iatrogenic obstruction of the spermatic duct or iatrogenic occulusive azospermia, in a wider context, is more frequently diagnosed today than it used to be in the past. this is attributable to general improvement of the system of andrological care. hints are given on avoidance of that lesion by surgical tactics as well as on provisional treatment and on compulsory notification of injuries that occurred to the spermatic duct. a rating of 20 to 30 per cent of disablement is proposed for irreversib ... | 1987 | 3591044 |
| prediction and detection of ovulation by the measurement of urinary pregnanetriol-3 alpha-glucuronide. a multicentre study. | the urine excretion pattern of pregnanetriol 3 alpha-glucuronide (pt-3g) throughout the menstrual cycle in 26 normal ovulating women was evaluated in a multicentre study. the concentration of pt-3g was measured by radioimmunoassay in daily samples of early morning urine (emu) from 20 women for three consecutive cycles and from 6 women who conceived during the period of study. pt-3g was also measured in 24-h urine samples from 5 additional women. the peak of urine lh was used as a reference point ... | 1986 | 3702465 |
| lymph heart musculature in birds. | development and innervation of the lymph heart musculature of chicken, emu, rhea, and duck was studied by electron microscopy at post-hatch ages from 3 days to adulthood. development of innervation was monitored by acetylcholinesterase staining. horseradish peroxidase was used to determine the extent of the transverse tubule network. chickens were unusual among these birds in that lymph heart myocytes had already undergone a definitive differentiation and degeneration by 3 days. in ducks and rat ... | 1987 | 3820312 |
| multimeric analysis of von willebrand factor in megakaryocytes. | von willebrand factor (vwf) is a glycoprotein that appears to play a major role in subserving the adhesion of platelets to subendothelium during hemostasis. endothelial cells have been shown capable of synthesizing and releasing this large, multimeric glycoprotein that normally circulates in the plasma in association with the factor viii coagulant molecule. megakaryocytes, the precursor cells of blood platelets, also appear to possess vwf biosynthetic capacity, since cultured guinea pig megakary ... | 1985 | 3875163 |
| osmotic and ionic regulation during dehydration in a large bird, the emu (dromaius novaehollandiae): an important role for the cloaca-rectum. | the emu, a large (40 kg) flightless bird, has low water requirements yet it has a limited ability to produce concentrated urine. to clarify the factors involved in excretion and water conservation by the emu the patterns of excretion during water restriction were examined. additionally, kidney function was studied, as also was the role of the cloaca and rectum in the final modification of excreta. following water restriction the osmolality of the excreta fluid increased to a maximum level at 6 d ... | 1985 | 4034920 |

| amino-acid sequence of feather keratin from fowl. | the amino acid sequence of a single polypeptide chain, b-4, from fowl feather barbs has been determined. the b-4 chain was found to consist of 96 amino acid residues and to have a molecular weight of 10206 in the s-carboxymethylated form. the n terminus of this protein was an n-acetylserine residue. the b-4 protein contained seven s-carboxymethylcysteine residues, six of which are located in the n-terminal region (residues 1-26), and other one in c terminus. the central region of the peptide cha ... | 1983 | 6189711 |
| some histochemical properties of the fiber types in the pectoralis muscle of an emu (dromaius novaehollandiae). | the muscle fibers of the cranial slip of m. pectoralis pars thoracica of an emu (dromaius novaehollandiae) were studied histochemically for intracellular lipid, succinic dehydrogenase, myofibrillar adenosine triphosphatase, and acetylcholinesterase. it was concluded that the muscle consisted of approximately 28% slow-tonic and 72% fast-twitch glycolytic fibers. the tonic fibers were considered to be characteristic of a postural muscle, and the fast-twitch glycolytic fibers to reflect the inabili ... | 1984 | 6235756 |
| the effect of two chemical mutagens enu and mms on mr-mediated reversion of an insertion-sequence mutation in drosophila melanogaster. | the effects of two mutagens enu and mms characterized by different alkylation patterns have been studied on the reversion of an mr-induced singed mutation to wild-type. reversion of this unstable singed mutation under the influence of mr is assumed to represent the removal or transposition of an insertion element. since mr acts primarily in spermatogonia, the mutagens were fed to 1st instar larvae. recessive lethal tests were carried out simultaneously to calibrate for the mutagenic effectivenes ... | 1983 | 6308435 |
| the measurement of urinary lh, by a solid-phase chemiluminescence immunoassay. | ovulation in women may be predicted or detected by a simple, solid-phase, chemiluminescence immunoassay for the measurement of urinary lh. an igg fraction of a donkey antiserum to rabbit immunoglobulins is passively adsorbed to the walls of polystyrene tubes. human chorionic gonadotrophin-succinyl-butyl-ethyl-isoluminol and a primary antibody (rabbit anti-human lh) is incubated with samples of early morning urine. after the binding reaction, the solution is removed by aspiration. the antibody-bo ... | 1984 | 6385812 |
| panting in the emu causes arterial hypoxemia. | the purpose of this study was to determine the effect of heavy thermal panting on arterial oxygen (pao2) and carbon dioxide (paco2) tension in emus. the birds showed no significant change in body temperature during a 3-4 h heat stress caused by increasing ambient air temperature from 21 to 46 degrees c. however, the emus increased their respiratory frequency 10-fold (from 5.3 to 52.9 breaths x min-1). the high respiratory frequency resulted in a slight but significant decrease in paco2 (from 33. ... | 1983 | 6420859 |
| ratites as oldest offshoot of avian stem--evidence from alpha-crystallin a sequences. | one of the most disputed issues in avian phylogeny is the origin of the ratites, the large flightless birds of the southern hemisphere (reviewed in refs 1-3). it is still not generally agreed whether the ostriches, rheas, emus and cassowaries, and probably kiwis, form a natural, monophyletic group, although much recent evidence supports this view. also, their phylogenetic relationship with the other avian orders remains unresolved, comparative protein sequence studies might shed new light on thi ... | 1984 | 6482951 |

| pharmacokinetics and tissue concentrations of tylosin in selected avian species. | tissue and plasma concentrations and the biological half-life of tylosin in avian species of a variety of body sizes and metabolic rates were studied. the species chosen were eastern bobwhite quail (colinus virginianus virginianus), pigeons (columba livia), greater sandhill cranes (grus canadensis tabida), and emus (dromaius novaehollandiae). in the 1st phase of this study, tylosin was administered im to quail, pigeons, and emus at a dosage rate of 25 mg/kg of body weight and to cranes at a dosa ... | 1982 | 7149381 |
| the measurement of urinary steroid glucuronides as indices of the fertile period in women. world health organization, task force on methods for the determination of the fertile period, special programme of research, development and research training in human reproduction. | the concentrations of various estrogen glucuronides and pregnanediol-3 alpha-glucuronide have been measured in daily samples of early morning urine (emu) and 24 h pooled collections throughout a total of 70 menstrual cycles (58 subjects). the immediate objective was to identify and assess the potential value of measuring hormone metabolites to locate the fertile period in women, with the ultimate aim of developing a non-invasive immunochemical test. the project was undertaken in five centres and ... | 1982 | 7176659 |
| the epididymis and its development in ratite birds (ostrich, emu, rhea). | the epididymis of ratitae is subdivided into a main part and a appendix epididymidis. the appendix epididymidis consists of the ductus aberrans and ductuli aberrantes. the ductus aberrans is the cranial continuation of the ductus epididymidis. the appendix epididymidis is cranially attached to the adrenal gland. in the main part of the epididymis the largest part of the rete testis is found. the rete testis is composed of an intratesticular rete (also named tubuli recti), and intracapsular rete ... | 1981 | 7270904 |
| the horizontal magnetic dance of the honeybee is compatible with a single-domain ferromagnetic magnetoreceptor. | although honeybees are able to sense the geomagnetic field, very little is known about the method in which they are able to detect it. the recent discovery of biochemically precipitated magnetite (fe3o4) in bees, however, suggests the possibility that they might use a simple compass organelle for magnetoreception. if so, their orientation accuracy ought to be related to the accuracy of the compass, e.g. it should be poor in a weak background fields and enhanced in strong fields. when dancing to ... | 1981 | 7295911 |
| practical detection of epileptiform discharges (eds) in the eeg using an artificial neural network: a comparison of raw and parameterized eeg data. | we have developed and tested "off-line" an artificial neural network (ann) that successfully detects epileptiform discharges (eds) when trained on eeg records marked by an electroencephalographer (eeger). the system was trained on both parameterized and raw eeg data and can process 49 channels of eeg data in real time on an 80486/33 mhz personal computer, making it capable of processing eeg on-line in long-term monitoring units. our detector consists of 2 stages: (1) a threshold detector identif ... | 1994 | 7522148 |
| the arachidonic acid content of the australian diet is lower than previously estimated. | linoleic acid [18:2(n-6)] is the most abundant polyunsaturated fatty acid in the western diet and is considered to be the primary source of tissue arachidonic acid [20:4(n-6)]. dietary 20:4(n-6) may also contribute to tissue 20:4(n-6) levels in humans, but the extent of this contribution is unclear. we believe that literature estimates of 20:4(n-6) intake of 200-1000 mg/d are too high, possibly because of incorrect values in food composition tables where high amounts of 20:4(n-6) are recorded in ... | 1995 | 7562087 |
| usefulness of early morning urine estrone-3-glucuronide assay in the monitoring ovarian secretory function in precocious puberty. | to evaluate the usefulness of the urinary estrone-3-glucuronide (ei-3-g) in the monitoring of the ovarian function in girls, we studied 11 girls with idiopathic central precocious puberty (icpp) treated with lhrh analogs (lhrha) for 2-5 years. plasma lh, fsh, 17-beta-estradiol (e2) levels, early morning urine (emu) e1-3-g concentrations, were assessed before and 3, 6, 12 months after the onset of treatment. as expected, mean basal plasma lh, fsh and e2 concentrations, as well as mean basal emu e ... | 1995 | 7629394 |
| the emu-bcl-2 transgene enhances antigen-induced germinal center formation in both balb/c and sjl mice but causes age-dependent germinal center hyperplasia only in the lymphoma-prone sjl strain. | emu-bcl-2 transgenic and littermate control balb/c and sjl mice were immunized in the front footpads with trinitrophenylated brucella abortus and the germinal center (gc) response in draining brachial lymph nodes was studied by staining with peanut agglutinin peroxidase and methyl green. although the gcs induced were not larger in transgenic than in control young mice, there was a significant increase in the percentage of b cell follicles exhibiting gcs 7 to 8 days after primary and secondary an ... | 1995 | 7639335 |
| gangliosidosis in emus (dromaius novaehollandiae). | a 6-month-old female emu (dromaius novaehollandiae) died following acute central nervous system signs. hematoxylin-and-eosin-stained sections revealed that neurons of the brain were distended with nonstaining 1-to-2-microns vacuoles. ultrastructural examination of the affected neurons revealed numerous membranous cytoplasmic bodies (mcbs) similar in appearance to the mcbs seen in mammalian gangliosidoses. a full sibling of this emu was donated for study. this 7-month-old female emu was stunted c ... | 2007 | 7677649 |
| the functional basis of c-myc and bcl-2 complementation during multistep lymphomagenesis in vivo. | oncogenes are known to be deregulated by chromosomal translocations occurring at high frequency in specific malignancies. among the most well characterized of these are c-myc, associated with the t(8;14) in burkitt's lymphomas, and bcl-2, associated with the t(14;18) in follicular lymphomas. in addition to their role in regulating rates of proliferation, it is known that oncogenes and tumor suppressor genes can also regulate rates of apoptotic cell death. the contribution of c-myc and bcl-2 to t ... | 1995 | 7698223 |
| general pattern and morphological specializations of the avian cochlea. | in different bird species, there is a common pattern in the hair-cell morphology and innervation of the basilar papilla; the absolute values, however, are species-specific. in the barn-owl papilla, an extreme being case, the basal high-frequency part of the papilla is greatly expanded. in this behaviorally most important frequency range of the barn owl, the number of afferent nerve terminals to neural hair cells is extensively increased. instead of about 2 afferent terminals as in other species, ... | 1994 | 7701304 |
| incidence of campylobacters in the intestine of avian species in alabama. | avian species necropsied at the c. s. roberts veterinary diagnostic laboratory, auburn, alabama, from december 1993 until may 1994 were examined for the incidence of intestinal campylobacters. ninety-one intestinal swabs, representing 66 separate cases and 17 different avian species, were collected and placed into cary-blair transport medium. selective enrichment and culture media were used for initial isolation of campylobacter spp. presumptive colonies were identified as campylobacter spp. by ... | 1995 | 7794175 |
| presence of avian influenza virus (aiv) subtypes h5n2 and h7n1 in emus (dromaius novaehollandiae) and rheas (rhea americana): virus isolation and serologic findings. | avian influenza virus (aiv) subtypes h5n2 and h7n1 were isolated from emus (dromaius novaehollandiae) and rheas (rhea americana) in texas and north carolina. all the rheas and emus had a history of respiratory disease except one emu, which was clinically normal. the isolates were not pathogenic for chickens and turkeys under the conditions of the experiment. humoral antibodies to all known hemagglutinin (h) subtypes except h10, h13, and h14 and to all nine neuraminidase (n) subtypes were found i ... | 1995 | 7794192 |
| regulatory regions 3' of the immunoglobulin heavy chain intronic enhancer differentially affect expression of a heavy chain transgene in resting and activated b cells. | we have compared the expression patterns of three ig heavy chain transgenes. the three constructs differ only by deletion of j-c intron sequences located downstream of the emu enhancer region. when stably transfected into a myeloma cell line, all three constructs are expressed at comparable levels. however, transgenic mice carrying each construct show dramatic differences in transgene expression. our results indicate that, in addition to the emu enhancer, at least two regions, rega and regs, wit ... | 1995 | 7868895 |
| sensitive and specific colorimetric dot assay to detect eastern equine encephalomyelitis viral rna in mosquitoes (diptera: culicidae) after polymerase chain reaction amplification. | a sensitive and specific colorimetric dot assay following polymerase chain reaction (pcr) method has been developed to detect 0.1 pg of eastern equine encephalomyelitis viral (eeev) rna. the assay is 250-fold more sensitive than analysis by electrophoresis and is based on converting a 291-nucleotide sequence of the viral coat protein amino terminus into a double-stranded dna (dsdna) and amplifying the dna using a specific primer pair and pcr. the amplified complementary dna (cdna) is denatured a ... | 1995 | 7869341 |
