oxidized low density lipoprotein inhibits lipopolysaccharide-induced binding of nuclear factor-kappab to dna and the subsequent expression of tumor necrosis factor-alpha and interleukin-1beta in macrophages.a large body of evidence suggests that oxidized ldl (oxldl) has a role in atherogenesis. one effect is the impact on macrophage function. we have studied the effects of oxldl and oxysterols on the binding of the transcription factors nuclear factor (nf)-kappab and ap-1 to dna. these transcription factors are involved in the regulation of several genes and expressed during activation of macrophages, for example by endotoxin (lps). oxldl did not induce binding of nf-kappab. however, the lps-induce ...19968690807
macrophage function in deer.macrophage inflammatory and immune functions were characterised in red deer (cervus elaphus), for use as a model for natural infection with bovine tuberculosis. highly enriched populations of deer macrophages were obtained from 14 day cultures of plastic-adherent peripheral blood mononuclear cells. cervine macrophages produced superoxide anion in response to respiratory burst stimuli (serum-opsonised zymosan and phorbol myristic acetate), but nitric oxide production could not be detected under t ...19968677637
multiple p21ras effector pathways regulate nuclear factor of activated t cells.the transcription factor, nuclear factor of activated t cells (nfat) is a major target for p21ras and calcium signalling pathways in the il-2 gene and is induced by p21ras signals acting in synergy with calcium/calcineurin signals. one p21ras effector pathway involves the map kinase erk-2, and we have examined its role in nfat regulation. expression of dominant negative mapkk-1 prevents nfat induction. constitutively active mapkk-1 fully activates erk-2 and the transcription factor elk-1, but do ...19968670897
determinants of dna-binding specificity of ets-domain transcription factors.several mechanisms are employed by members of transcription factor families to achieve sequence-specific dna recognition. in this study, we have investigated how members of the ets-domain transcription factor family achieve such specificity. we have used the ternary complex factor (tcf) subfamily as an example. erk2 mitogen-activated protein kinase stimulates serum response factor-dependent and autonomous dna binding by the tcfs elk-1 and sap-la. phosphorylated elk-1 and sap-la exhibit specifici ...19968668149
cdna cloning, molecular characterization, and chromosomal localization of net(epht2), a human eph-related receptor protein-tyrosine kinase gene preferentially expressed in brain.by screening a human fetal brain cdna expression library using a monoclonal anti-phosphotyrosine antibody, we have isolated a cdna clone encoding a receptor type protein-tyrosine kinase belonging to the eph family, net (neuronally expressed eph-related tyrosine kinase). net shows 87% homology in nucleotide sequence and 99% homology in the deduced amino acid sequence to rat elk, suggesting that net is the human homologue of elk. the net gene is mapped to human chromosome 3q21-q23 by pcr screening ...19958666391
primary care physicians' use of office resources in the provision of preventive care.to assess (1) the extent to which office resources (eg, chart aids, educational materials, office staff) are used by primary care physicians in the provision of preventive care; (2) the characteristics of physicians associated with this use; and (3) the relationship of office resource use to reported preventive service provision.19968664998

forest planning in an oregon case study: defining the problem and attempting to meet goals with a spatial-analysis techniquefive major management goals were identified for the upper grande ronde river basin on the wallowa-whitman national forest in northeastern oregon: to produce high-quality fish habitat, to maintain elk habitat, to restore and maintain forest conditions within the natural range of viability, and to contribute to community economic stability. from the broad goals, specific goals for stream temperature, habitat effectiveness index (hei), habitat corridors, maintenance of land in late or old seral sta ...19968661622
the gene encoding lerk-7 (eplg7, epl7), a ligand for the eph-related receptor tyrosine kinases, maps to human chromosome 5 at band q21 and to mouse chromosome 17.the eph-related receptors are the largest subfamily of receptor tyrosine kinases. recently, we and others have identified seven different, but related, cdnas encoding membrane-bound ligands for this family of receptors. one member, lerk-7, is attached to the cell membrane via glycosyl-phosphatidylinositol linkage and has been found to be a ligand for the eph-family receptors hek, elk, eck, and rek. using pcr-based screening of human x rodent somatic cell hybrid dnas, we have assigned the gene th ...19968661153
the genes encoding the eph-related receptor tyrosine kinase ligands lerk-1 (eplg1, epl1), lerk-3 (eplg3, epl3), and lerk-4 (eplg4, epl4) are clustered on human chromosome 1 and mouse chromosome 3.hek and elk are members of the eph-related family of receptor tyrosine kinases. recently, we isolated five cdnas encoding membrane-bound ligands to hek and elk. because of the promiscuous nature of their binding, we have termed these proteins ligands of the eph-related kinases or lerks. the lerks can be divided into two subgroups by virtue of their sequence identity, binding properties, and mode of cell membrane attachment. for example, lerk-2 (eplg2, epl2) and lerk-5 (eplg5, epl5) are type 1 tr ...19968660976

structural changes in fluorosed dental enamel of red deer (cervus elaphus l.) from a region with severe environmental pollution by fluorides.a macroscopic, microradiographic and scanning electron microscope study was performed on the structure of fluorosed dental enamel in red deer from a fluoride polluted region (north bohemia, czech republic). as was revealed by analysis of mandibular bone fluoride content, the rate of skeletal fluoride accumulation in the fluorotic deer was about 6 times that in controls taken from a region not exposed to excessive fluoride deposition. in all fluorosed mandibles, the 1st molar was consistently les ...19968655406
selective interaction of jnk protein kinase isoforms with transcription factors.the jnk protein kinase is a member of the map kinase group that is activated in response to dual phosphorylation on threonine and tyrosine. ten jnk isoforms were identified in human brain by molecular cloning. these protein kinases correspond to alternatively spliced isoforms derived from the jnk1, jnk2 and jnk3 genes. the protein kinase activity of these jnk isoforms was measured using the transcription factors atf2, elk-1 and members of the jun family as substrates. treatment of cells with int ...19968654373
occupational asthma due to deer dander.the literature on allergy to deer is limited. the allergenic component remains to be identified.19968630715
susceptibility of elk (cervus elaphus) to experimental infection with anaplasma marginale and a. ovis.anaplasma ovis was experimentally transmitted from domestic sheep to elk (cervus elaphus) and back to splenectomized sheep. no rickettsemias were detected but serum from three of seven experimentally inoculated elk developed anaplasma spp.-reactive antibody as measured by indirect immunofluorescence (iif) or by the rapid card agglutination and complement fixation assays. three elk were experimentally infected with a. marginale. the rickettsiae were detected in blood of these elk and caused disea ...19968627938
seroprevalence of psoroptes sp. mites in free-ranging elk (cervus elaphus) as determined by kinetic elisa.western blots and a kinetic enzyme-linked immunosorbent assay (elisa) were used to characterize and quantify the prevalence of antibodies to psoroptes sp. mites in elk (cervus elaphus) from nine herds in north america. sera from infested (n = 18) and non-infested (n = 22) elk were used to optimize test methodology and to define cut-off values for negative, suspect, and positive samples. among 357 samples, 35 (9.8%) of the animals were seropositive, 259 (73%) were negative, and 63 (18%) were susp ...19968627936
leptospira interrogans exposure in free-ranging elk in washington.exposure to one or more serovars of leptospira interrogans was observed in five of six sampled elk (cervus elaphus roosevelti) killed in november 1993, from an isolated herd in southwest washington, usa (46 degrees 45'n, 123 degrees 6'w). in april 1994, exposure to l. interrogans serovars was documented in nine of 11 captured cow elk from the same herd. leptospires were not isolated from any of the exposed elk, and 10 of the 11 cows were pregnant. the high seroprevalence is evidence that exposur ...19968627923
mkk3- and mkk6-regulated gene expression is mediated by the p38 mitogen-activated protein kinase signal transduction pathway.the p38 mitogen-activated protein (map) kinase signal transduction pathway is activated by proinflammatory cytokines and environmental stress. the detection of p38 map kinase in the nucleus of activated cells suggests that p38 map kinase can mediate signaling to the nucleus. to test this hypothesis, we constructed expression vectors for activated mkk3 and mkk6, two map kinase kinases that phosphorylate and activate p38 map kinase. expression of activated mkk3 and mkk6 in cultured cells caused a ...19968622669
multiple requirements for shptp2 in epidermal growth factor-mediated cell cycle progression.using transient overexpression and microinjection approaches, we examined shptp2's function in growth factor signaling. overexpression of catalytically inactive shptp2 (ptp2cs) but not catalytically inactive shptp1, inhibited mitogen-activated protein (map) kinase activation and elk-1 transactivation following epidermal growth factor (egf) stimulation of 293 cells. an shptp2 mutant with both c-terminal tyrosyl phosphorylation sites converted to phenylalanine (ptp2yf) was also without effect; mor ...19968622663
phosphorylation-dependent formation of a quaternary complex at the c-fos sre.the rapid and transient induction of the human proto-oncogene c-fos in response to a variety of stimuli depends on the serum responses element (sre). in vivo footprinting experiments show that this promoter element is bound by a multicomponent complex including the serum response factor (srf) and a ternary complex factor such as elk-1. srf is thought to recruit a ternary complex factor monomer into an asymmetric complex. in this report, we describe a quaternary complex over the sre which, in add ...19968622654
signal transduction pathways regulated by mitogen-activated/extracellular response kinase kinase kinase induce cell death.mitogen-activated/extracellular response kinase kinase (mek) kinase (mekk) is a serine-threonine kinase that regulates sequential protein phosphorylation pathways, leading to the activation of mitogen-activated protein kinases (mapk), including members of the jun kinase (jnk)/stress-activated protein kinase (sapk) family. in swiss 3t3 and ref52 fibroblasts, activated mekk induces cell death involving cytoplasmic shrinkage, nuclear condensation, and dna fragmentation characteristic of apoptosis. ...19968621725
the conserved elk-homeodomain of knotted-1 contains two regions that signal nuclear localization.nuclear localization serves as a regulatory mechanism in the activity of several transcription factors. knotted-1 (kn1) is a homeodomain protein likely to regulate vegetative development in maize. at least twelve genes related to kn1 are known in maize and six in arabidopsis. ectopic expression of the maize, rice and arabidopsis kn1-related genes have been shown to alter cell fate determination. in this paper, we study the nuclear localization capabilities of the kn1 homeodomain and the proximal ...19968616227
elk-1 can recruit srf to form a ternary complex upon the serum response element.the initial genomic response to serum growth factors is the transcriptional activation of a set of immediate-early genes. serum-induced transcriptional activation of several of these genes involves the formation of a ternary complex that includes the serum response factor (srf), a 62 kda ternary complex factor (tcf) and a serum response element (sre). tcf alone does not bind the sre of the protooncogene c-fos, but requires the prior assembly of the srf-sre binary complex for it to be recruited i ...19968614640
transcriptional regulation by map kinases.tyrosine kinase growth factor receptors activate map kinase by a complex mechanism involving the sh2/3 protein grb2, the exchange protein sos, and ras. the gtp-bound ras protein binds to the raf kinase and initiates a protein kinase cascade that leads to map kinase activation. three map kinase kinase kinases have been described--c-raf, c-mos, and mekk--that phosphorylate and activate mek, the map kinase kinase. activated mek phosphorylates and activates map kinase. subsequently, the activated ma ...19958607977
radionuclide uptake by red deer (cervus elaphus) on mountain grazing.forty-two red deer (cervus elaphus) were shot during the 1992 annual cull in glenveagh national park, ireland. samples of rumen, kidney and faeces were removed from each animal. kidney samples were used to estimate flesh radiocaesium (137cs) concentrations and the 95% confidence interval for the mean was 203 +/- 12 bq kg-1. the maximum recorded 137cs concentration in kidney was 367 bq kg-1 (fresh weight). the altitude of the cull, the age and sex of each animal were recorded. neither age nor sex ...19958605580
effects of season and nutrition on growth hormone and insulin-like growth factor-i in male red deer.gh and insulin-like growth factor (igf)-i are important components of the growth axis. we undertook to determine how plasma levels of these hormones altered with different seasonal and nutritional states in young male red deer to provide an insight into how the growth axis changes under these conditions. growth rate alters dramatically with season in male red deer, providing an opportunity to sample the same animals at two different growth rates within a short period of time. gh was measured eve ...19968593820
[serologic investigations on the occurrence of maedi-visna antibodies in game ruminants].the lentiviruses of small domestic ruminants (maedi-visna and caprine arthritis-encephalitis virus) have been shown to be infective for each other. there are only few investigations of virus susceptibility of other species of animals. the aim of our study reported here was to evaluate sera of wild animal species for lentivirus antibodies. 344 sera of capreolus capreolus, cervus elaphus and dama dama from a territory with known sheep populations prevalence were tested in the agar gel immunodiffus ...19958593775
diagnosing pregnancy in free-ranging elk using fecal steroid metabolites.we validated fecal metabolite analysis as a noninvasive means of diagnosing pregnancy in uncaptured, free-ranging rocky mountain elk (cervus elaphus nelsoni). during november 1991, we collected blood samples from 21 radiocollared, 1- to 10-year-old female elk in yellowstone national park, wyoming (usa), and determined their pregnancy status by radioimmunoassay of serum pregnancy specific protein b and serum progesterone concentrations. from december 1991 through april 1992, we collected three to ...19958592383
studies on the hypodermosis affecting red deer in central and southern spain.from november 1992 to february 1993, 455 red deer (cervus elaphus) were surveyed in order to estimate the prevalence of warble fly (hypoderma actaeon) larvae under the skin of this ungulate species. material came from montes de toledo, sierra morena, sierra de alcaraz, and sierras de cazorla, segura y las villas natural park (central and southern spain). we observed a prevalence of 92%, with a mean +/- sd intensity of 35.7 +/- 41.3 grubs per parasitized host; there was a maximum of 317 larvae pe ...19958592379
experimental infections of sarcocystis spp. in rocky mountain elk (cervus elaphus) calves.four 4-mo-old elk calves (cervus elaphus) obtained from northeastern oregon (usa) each were inoculated orally with 250,000 sporocysts of sarcocystis spp., including s. sybillensis and s. wapiti. three similar elk calves of comparable ages and weights served as uninoculated controls maintained with the inoculated elk during the experimental period between september and december 1993. body weights were evaluated at 0 and 90 days postinoculation (pi); packed cell volumes of whole blood were evaluat ...19958592375
application of a competitive elisa for the detection of bluetongue virus antibodies in llamas and wild ruminants.a competitive enzyme-linked immunosorbent assay (c-elisa), using a group-specific monoclonal antibody against bluetongue virus (btv), was applied to detect anti-btv antibodies in serum samples from two llamas (llama glama) experimentally infected with btv serotype 10. antibodies were detected in both llamas by 1 wk or 2 wk post-infection. antibodies to btv increased exponentially during the first 4 wk in both llamas and stabilized at an elevated level during the remaining 5-wk-period of the expe ...19958592352
simultaneous comparison between transtympanic and extratympanic electrocochleography.electrocochleography (ecog) has become a mainstay in the diagnostic armamentarium used by otolaryngologists and audiologists in the evaluation of patients suffering auditory and vestibular symptoms. controversy exists, however, regarding the relative accuracy of ecog when recorded with a non-invasive external auditory canal (eac) electrode as compared to that recorded using a transtympanic electrode. in an effort to resolve this controversy, 19 healthy volunteers (37 ears) with no history of oto ...19958588643
neither erk nor jnk/sapk map kinase subtypes are essential for histone h3/hmg-14 phosphorylation or c-fos and c-jun induction.the effects of egf, tpa, uv radiation, okadaic acid and anisomycin on erk and jnk/sapk map kinase cascades have been compared with their ability to elicit histone h3/hmg-14 phosphorylation and induce c-fos and c-jun in c3h 10t1/2 cells. egf and uv radiation activate both erks and jnk/sapks but to markedly different extents; egf activates erks more strongly than jnk/sapks, whereas uv radiation activates jnk/sapks much more strongly than erks. anisomycin and okadaic acid activate jnk/sapks but not ...19958586671
immobilization of rocky mountain elk with telazol and xylazine hydrochloride, and antagonism by yohimbine hydrochloride.ten trapped rocky mountain elk (cervus elaphus nelsoni) were successfully immobilized with a combination of 500 mg telazol and 60 mg xylazine hydrochloride (hcl) from 9 july to 25 august 1993 in custer state park, south dakota (usa). mean (sd) dosages of 2.5 (0.6) mg/kg telazol and 0.3 (0.1) mg/kg xylazine hcl, respectively, were administered, resulting in a mean (sd) induction time of 4.6 (0.8) min. induction time varied with weight and dosage. respiratory rate (breaths/min) increased following ...19958583649
bovine virus diarrhea and mucosal disease in free-ranging and captive deer (cervidae) in germany.from 1990 until 1992, 355 blood samples of roe deer (capreolus capreolus) (n = 123), red deer (cervus elaphus) (n = 60), fallow deer (dama dama) (n = 87) and other cervid species (n = 85) from three different habitats (n = 180) and 11 wildlife parks or zoos (n = 175) in germany were tested for prevalence of pestivirus antibodies. seventeen samples were seropositive for bovine viral diarrhea virus (bvdv); only one animal had antibodies for border disease virus. microneutralization test titers ran ...19958583646
[evaluation of the meat quality of game].the carcasses of 140 roe deer, 129 wild boars, 81 red deer and 55 fallow deer were examined to determine meat quality with respect to the influence of typical hunting situations. after hunting, many carcasses had not been cooled, which significantly influenced meat-quality parameters. the ph-value, detected electrochemically, gave the most reliable results out of all the meat-quality parameters investigated. determination of the ph-value with regard to the ph indexes ascertained for different po ...19958578914
locations of the ets subfamily members net, elk1, and sap1 (elk3, elk1, and elk4) on three homologous regions of the mouse and human genomes.net, elk1, and sap1 are related members of the ets oncoprotein family. we show by in situ hybridization on banded chromosomes with specific cdna probes that their map positions on mouse and human chromosomes (respectively) are net, 10c-d1 and 12q22-q23 (now called elk3), sap1, 1e3-g and 1q32 (elk4), and elk1, xa1-a3 and xp11.2-p11.1 (elk1), as well as a second locus 14q32 (elk2) unique to the human genome. the results for the mouse net, sap1, and elk1 and human elk3 genes are new. the human elk1 ...19958575773
ligands for eph-related tyrosine kinase receptors are developmentally regulated in the cns.elk is a member of the eph family of receptor-like tyrosine kinases. although its function is unknown, elk is postulated to play a role in nervous system development. using northern analysis, we examined the developmental regulation of rnas encoding elk, and several ligands for the eph family of rtks, the lerks. expression of elk, lerk-1, and lerk-2 rnas is high in all regions examined in the embryonic and postnatal rat brain and decreases to low levels with age. one exception is the adult olfac ...19958568920
plant compositional constituents affecting between-plant and animal species prediction of forage intake.the purpose of the study was to identify plant compositional constituents that influence forage intake. emphasis was put on the ratio in vitro digestibility of organic matter (ivdom):ndf because preliminary work with cattle and a limited number of forages showed the ratio to account for more variation in intake than either ivdom or ndf alone. the compositional constituents were tested in intake prediction models using local and published data (n = 302) on grass pastures, silages, hays, straws, l ...19958567482
pasteurellosis in elk (cervus elaphus): dna fingerprinting of isolates. 19958560727
isolation of lerk-5: a ligand of the eph-related receptor tyrosine kinases.hek and elk are members of the eph-related family of receptor tyrosine kinases. recently we isolated four cdnas encoding membrane-bound ligands to hek and elk [beckman et al. (1994) embo j. 13, 3757-3762; kozlosky et al. (1995) oncogene 10, 299-306]. because of the promiscuous nature of their binding, we have termed these proteins ligands of the eph-related kinases or lerks. a search of genbank revealed an expressed sequence tag (est) with homology to the lerks. using this est as a probe, we hav ...19958559144
activation of ternary complex factor elk-1 by stress-activated protein kinases.the mammalian response to stress results in the activation of stress-activated protein kinases (also known as cjun n-terminal kinases; sapks or jnks), which are a sub-group of the mitogen-activated protein (map) kinase family. the sapks are involved in the upregulation of activity of the transcription factor ap-1 by post-translational modification of two of its components, cjun and atf2. ap-1 activity can also be elevated by increased expression of the fos protein, a further ap-1 component. elk- ...19958548291
serum response element and flanking sequences mediate the synergistic transcriptional activation of c-fos by 12-o-tetradecanoylphorbol-13-acetate and cholera toxin in akr-2b cells.12-o-tetradecanoylphorbol-13-acetate (tpa) and cholera toxin have been shown previously to act synergistically to stimulate traverse of g0-g1 and entry into s phase in quiescent mouse fibroblasts. these agents also have a synergistic effect on the induction of the endogenous c-fos gene, as well as a transfected reporter construct containing the mouse fos promoter/enhancer region from -397 to +1 cloned upstream of luciferase. a detailed mutational analysis of the c-fos-regulatory region revealed ...19958547224
embryo brain kinase: a novel gene of the eph/elk receptor tyrosine kinase family.a new gene belonging to the eph/eck/elk receptor tyrosine kinase family has been cloned from mouse brain. the gene maps to mouse chromosome 4. in the adult brain it is expressed exclusively and abundantly in the hippocampus. we propose to name it ebk (embryo brain kinase), as in situ hybridisation shows expression in many parts of the developing mouse brain. the most abundant expression is in the subcommissural organ, and the earliest expression is in the forebrain neural folds, in rhombomeres 2 ...19958541219

occurrence and overlapping of pharyngeal bot flies pharyngomyia picta and cephenemyia auribarbis (oestridae) in red deer of southern spain.from 1985 to 1990, 372 red deer (cervus elaphus) from southern spain were examined for larvae of pharyngeal bot flies pharyngomyia picta and cephenemyia auribarbis. the infestation was related to age, sex and intensity of infection. fawns and adult deer (more than 5 years old) had a significantly (p < 0.05) higher prevalence and intensity of infection than younger deer. conversely, no significant difference has been noted between sexes. ninety percent of deer were found to be infested. a simulta ...19938493758
[microstructure of fossil mammalian bones from the rixdorfer horizon of weichsel-kaltzeit at niederlehme near königs wusterhausen (brandengurg)].the structure is reported of bones of glacial-period mammals, which were found in 1973 to 1989 in gravel-sandy soil of the fossiliferous layer "rixdorfer horizont" at niederlehme near königs wusterhausen. the findings, probably, date from one of the interstages of the glacial period "weichsel-kaltzeit" before the stage "brandenburger stadium". their embedding took place more than 20,000 years ago. changes of the deposit of bones and teeth from older sediments are not to exclude in the finding pl ...19938489038
[occurrence of leptospira antibodies in the blood of game animals].the blood serum of game was examined for the presence of antibodies to leptospiras in 1987-1989. a total of 792 blood sera from animals belonging to 14 zoo-species were examined (tab. i). the blood serum of red deer (cervus elephus) was examined the most often within the group of animals, in 398 cases, i.e. 50.2%, followed by 165 blood sera of wild boar (sus scrofa), representing 20.8%, and by 136 blood sera of roedeer (capreolus capreolus), representing 18.6%. small numbers of blood sera of the ...19938488630
functional analysis of a growth factor-responsive transcription factor complex.serum response factor (srf) forms a ternary complex at the c-fos serum response element (sre) with an accessory factor, elk-1. we constructed altered-binding specificity derivatives of srf and elk-1 that form a ternary complex at a mutated, inactive sre; like elk-1, the elk-1 variant only binds its target as part of a ternary complex with srf. simultaneous expression of these srf and elk-1 derivatives restores serum-regulated activity to the mutated sre in transfected cells. efficient transcript ...19938477450
nematode egg output and plasma concentration of ivermectin after its administration to red deer (cervus elaphus elaphus).blood and faecal samples were analysed in a study to evaluate the use of ivermectin in red deer hinds (cervus elaphus elaphus). it was demonstrated that ivermectin, when used at 400 micrograms/kg bodyweight, proved to be more efficient than 200 micrograms/kg bodyweight although positive worm egg counts together with the isolation of lungworm (dictyocaulus species) larvae were recorded from hinds having received the anthelmintic at the higher dose.19938456547
