genetic polymorphism of erythrocyte diaphorase in red deer, cervus elaphus l.nadh diaphorase polymorphism was identified in red deer erythrocyte lysates using starch gel electrophoresis and activity staining. the inheritance of the polymorphism was consistent with predictions of autosomal codominant inheritance of two alleles dia1f and dias. in new zealand's four main feral red deer populations (n = 188) the dia1f allele frequency ranged from 0.491 to 0.985. a sample of north american wapiti (n = 42) was monomorphic for the dia1f allele.19921416251
spatial flexibility in ternary complexes between srf and its accessory proteins.we investigated the sequence requirements for ternary complex formation by the transcription factor srf and its ets domain accessory factors elk-1 and sap-1. ternary complex formation is specified by an srf consensus site cc(a/t)6gg and a neighbouring ets motif (c/a)(c/a)gga(a/t), which is contacted by elk-1/sap-1. both the spacing of these sequences and their relative orientation can be substantially altered with little effect on the efficiency of ternary complex formation. efficient ternary co ...19921425594
purification, partial characterization, and heterologous radioimmunoassay of growth hormone (cgh) in red deer growth hormone (cgh; 3.3 mg) was purified from an aqueous extract of seven pituitary glands (4.01 g wet weight) by preparative gel filtration on sephadex g-100, gel filtration on sephadex g-100 sf, and anion exchange chromatography on deae-sepharose cl-6b. purified cgh gave a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis with a molecular weight under reducing conditions of 20,000 da and gave a single peak on reverse-phase high-performance liquid chromatography ...19921426952
relationship between the onset of oestrus, the preovulatory surge in luteinizing hormone and ovulation following oestrous synchronization and superovulation of farmed red deer (cervus elaphus).the timing of ovulation relative to the onset of oestrus and the preovulatory surge in luteinizing hormone (lh) was studied in red deer following treatments to synchronize oestrus and induce either a monovulatory or superovulatory response. mature hinds (n = 36) were allocated randomly to two mating groups (n = 16 + 20), with respective treatments staggered by 4 weeks during the 1990 rut (march-april). each hind was treated with an intravaginal controlled internal drug releasing (cidr)-type s de ...19921432958
elk-1 domains responsible for autonomous dna binding, sre:srf interaction and negative regulation of dna binding.the ets oncogene superfamily consists of a family of sequence-specific dna-binding transcriptional activator proteins. we have previously identified, cloned and characterized one of the divergent ets-related members elk-1 and shown that it codes for a sequence-specific dna-binding transcriptional activator. we have also shown that elk-1 forms srf (serum response factor) dependent ternary complex with sre (serum response element), similar to p62tcf. in this report, we have mapped the dna-binding ...19921437156
affinity purification of histidine-tagged proteins transiently produced in hela order to produce eukaryotic proteins in a functional state, it is often necessary to use eukaryotic instead of prokaryotic expression systems. we have designed vectors which can be employed to express either n- or c-terminally histidine-tagged proteins in transiently transfected eukaryotic cells. the histidine tag allows the rapid enrichment of these proteins by metal chelate affinity chromatography in a native and functional state. yields of up to 5 micrograms protein/5 x 10(7) cells were ac ...19921446830
mycobacterium bovis infection in north american elk (cervus elaphus).a naturally occurring outbreak of mycobacterium bovis infection in captive wild elk (wapiti) in montana was confirmed by mycobacteriologic examination. twenty-eight of 143 elk responded to m. bovis purified protein derivative (ppd) tuberculin injected intradermally in the cervical region (sct). the results of comparative cervical tuberculin skin tests conducted within 9 days of sct revealed greater responses to m. bovis ppd tuberculin than to m. avium ppd tuberculin in 23 of 28 elk responding. a ...19921457545
gross and microscopic lesions of naturally occurring tuberculosis in a captive herd of wapiti (cervus elaphus nelsoni) in colorado.a mycobacterium bovis-infected herd of captive wapiti (cervus elaphus nelsoni) in colorado was depopulated after lesions of bovine tuberculosis were confirmed in 8 of 10 tuberculin skin test reactors. of the 43 animals > 1 year of age, 26 had gross lesions suggestive of tuberculosis, 24 had microscopic lesions of tuberculosis, and 23 had acid-fast bacilli associated with the lesions. lungs and retropharyngeal lymph nodes were the most frequently affected sites. most lesions grossly and microscop ...19921457546

studies on the blood of fallow deer (dama dama) and red deer (cervus elaphus): haematology, red cell enzymes, metabolic intermediates and glycolytic rates.1. blood samples were obtained from fallow deer (dama dama) and red deer (cervus elaphus). basic haematology, red cell enzymes, and metabolic intermediates and the glycolytic rate of the red cells incubated with different substrates were measured. 2. the major findings were (i) the activity of glucose phosphate isomerase was notably high in the red blood cells of the red deer; (ii) red deer cells also utilized adenosine more efficiently than those of fallow deer and (iii) red cells of both speci ...19921478069
big game species identification by deoxyribonucleic acid (dna) probes.species identification is important in many big game forensic science cases but cannot always be accomplished because of the lack of adequate techniques. the authors have developed deoxyribonucleic acid (dna) probes for elk, deer, and antelope by isolating highly repeated satellite sequences. these dna probes distinguish among deer, elk, and antelope, although not between different species of deer. because of the high number of sequence copies per genome, these probes are extremely sensitive, re ...19921500901
the ets gene family.ets proteins have a conserved dna-binding domain and regulate transcriptional initiation from a variety of cellular and viral gene promoter and enhancer elements. some members of the ets family, ets-1 and ets-2, cooperate in transcription with the ap-1 transcription factor, the product of the proto-oncogene families, fos and jun, while others, elk-1 and sap-1, form ternary complexes with the serum response factor (srf). certain ets gene family members possess transforming activity while others a ...19921502727
genetic polymorphism of plasminogen and vitamin d binding protein in red deer (cervus elaphus l.).genetic polymorphism was detected in the red deer (cervus elaphus l.), plasma proteins, plasminogen (plg) and vitamin d binding protein (gc) using antiserum to human proteins. the affinity of the antisera to deer plasma was less than 10% that of a human standard but they bound specifically to proteins of molecular weight expected for gc and plg. three codominant alleles of gc and five of plg were observed. in a set 124 farmed deer calves and their parents, six calves had genotypes which were not ...19921503269
seasonal variation in venison quality of mature, farmed red deer stags in new zealand.two studies involving 20 red deer (cervus elaphus) stags were conducted to determine the effects of season on venison quality. in each study, five sexually mature red deer stags were slaughtered immediately preceding the rut (autumn) and five were slaughtered after the rut. stags slaughtered postrut had lower carcass weights (25 to 30%) than those slaughtered prerut. average bodywall thickness measurements above the 12th rib (an indicator of fat thickness) were approximately 31 mm prerut compare ...19921526907
requirement of thyroid function for the expression of seasonal reproductive and related changes in red deer (cervus elaphus) stags.the effect of thyroid function on regulation of seasonal reproduction was investigated in three red deer stags thyroidectomized (thx) in summer (january 1988) in comparison with five thyroid-intact controls. responses of luteinizing hormone (lh) and testosterone to a bolus injection of 10 micrograms gonadotrophin-releasing hormone (gnrh) were tested in july, october, december, february and april. blood samples were collected at weekly intervals from december 1987 to june 1989 for measurement of ...19921552486
cryptosporidiosis in newborn red deer (cervus elaphus).red deer calves dying at 24 to 72 hours old were infected with cryptosporidia. the clinical signs were extreme depression and weakness, but they did not consistently have diarrhoea. one calf was severely uraemic, and evidence from subsequent cases suggested that cryptosporidium infection in very young red deer calves may result in terminal uraemia. the possibility of intrauterine infection is considered. the factors which could have predisposed to the outbreak of infection were investigated; the ...19921561743

[spongiform encephalopathies with special reference to bovine spongiform encephalopathy].in switzerland bovine spongiform encephalopathy (bse) was detected for the first time in november 1990. it is a transmissible disease of the central nervous system similar to creutzfeldt-jakob disease (cjd), gerstmann-sträussler-scheinker syndrome (gss) and kuru in man, and, in animals, scrapie in sheep and goats, chronic wasting disease (cwd) in captive mule deer and elk of north america and transmissible mink encephalopathy (tme) of farm reared mink. the infectious agent of the spongiform ence ...19921615298
spongiform encephalopathies in cervidae.the known host range of naturally-occurring transmissible spongiform encephalopathies has expanded in recent years to include wild ruminants. chronic wasting disease (cwd) occurs in mule deer (odocoileus hemionus hemionus) and rocky mountain elk (cervus elaphus nelsoni) in colorado and wyoming, united states of america. these species belong to the family cervidae. cases have occurred primarily in captive animals but a few affected free-ranging animals have been identified. clinical disease in bo ...19921617203
effects of melatonin implants on insulin-like growth factor 1 in male red deer (cervus elaphus).red deer stags have a seasonal pattern of growth, alternating between periods of summer weight gain and winter weight loss that are influenced by photoperiod and by exogenous melatonin. a seasonal pattern of plasma insulin-like growth factor 1, also influenced by photoperiod, underlies the seasonal growth pattern. the present studies aimed to determine the influence of exogenous melatonin, administered at various times of the year, on plasma igf1 in adult red deer stags in new zealand at 45 degr ...19921624090
elk-1 protein domains required for direct and srf-assisted dna-binding.the ets-related elk-1 protein can bind to purine-rich dna target sites in a sequence specific fashion and, in addition, can form a ternary complex with the c-fos serum response element (sre) and the serum response factor (srf). we demonstrate that elk-1 can readily interchange between its different interaction partners. the amino terminal ets-domain of elk-1 was shown to be necessary and sufficient for direct dna-binding activity. for ternary complex formation with the sre and srf, both the elk- ...19921630903
creep fracture in bones with different stiffnesses.creep fracture experiments were used to examine the differences in time to fracture of bones with very different young's moduli (bovine bone and red deer antler) and the implications of these differences for the 'cumulative-damage' model of caler and carter [j. biomechanics 22, 625-635 (1989)] for bone fracture. using normalised stress as the explanatory variable, the slopes of the distributions agreed quite well with that of caler and carter for human bone. however, antler took far longer to fr ...19921733979
a divergent ets-related protein, elk-1, recognizes similar c-ets-1 proto-oncogene target sequences and acts as a transcriptional activator.the ets oncogene superfamily consists of a family of sequence-specific dna-binding proteins that activate transcription. we have previously identified two new members of the ets oncogene superfamily, namely elk-1 and elk-2. in this report we show that the recombinant elk-1 protein expressed in bacteria, like the c-ets-1 proto-oncogene, binds in a sequence-specific manner to moloney murine sarcoma virus long terminal repeat, e74 target sequences and the pea3 motif (polyoma enhancer), but does not ...19921741166
occurrence of fumonisin in forage grass in new zealand.fumonisin b(1) (fb(1)) was isolated from samples of forage grass originating in paddocks associated with an idiopathic disease of canadian wapiti and wapiti-red deer hybrids characterized by "ill thrift" and liver dysfunction. four of 40 samples contained 1, 3, 6, and 9 ppm (micrograms per gram) of fb(1) and 4, 0.5, 2, and 0.5 ppm, respectively, of the methyl ester of fb(1). analyses were done by ion spray mass spectrometry and confirmed by both fast atom bombardment (solids probe) and mass spec ...199216348778
behavioural and heart rate responses to velvet antler removal in red deer.heart rate and behaviour during and following velvet antler removal were monitored in yearling red deer stags to determine the extent to which this procedure was perceived by the deer to be aversive. nine stags normally kept at pasture were habituated over 5 weeks to the following daily handling procedure. each deer was fitted with a harness containing a heart rate monitor. it was then allowed to run through a fixed course in a deer yard, restrained for 40 s in a mechanical deer crush, and then ...199216031658
red urine from red deer grazed on pure red clover swards.twenty-four red deer hinds with their calves were released on to a newly established pure red clover sward and, 2 days later, red staining of the tail, perineum and hocks was observed. this was presumed to be of urinary origin. observation of micturition showed that when urine was passed, it was a normal straw colour but it turned scarlet-red about 1 hour after exposure to air. midstream urine remained the normal colour when held under a pure nitrogen atmosphere immediately after micturition, bu ...199216031683
electrical stunning of red deer (cervus elaphus).eighteen of 23 red deer (cervus elaphus) at a deer slaughtering premises were successfully stunned with an apparatus modified from that normally used to stun sheep. the five unsuccessful electrical stuns were associated with poor head restraint and poor head contact by the electrodes. the median stunning current was 0.9 a, and in the majority of cases the duration of stunning was less than 1 second. the signs of the electrically induced epileptiform seizures in the deer were dissimilar to those ...199316031710
efficacy of slow-release albendazole capsules in controlling lungworms and gastro-intestinal nematodes in red deer (cervus elaphus).one hundred and fifteen young red deer (cervus elaphus), heavily infected with lungworm (dictyocaulus viviparus) and lightly infected with gastro-intestinal nematodes, were divided into three groups. one group of 50 animals was treated with one adult sheep dose of a slow-release albendazole capsule, another group of 50 was dosed orally five times with liquid albendazole and 15 were left as untreated controls. the capsule eliminated faecal lungworm larvae during the 103-day trial period. there wa ...199316031711

noninvasive electrodes for electrocochleography in the chinchilla.this study compares noninvasive vs invasive electrodes for electrocochleography in chinchillas. summating potential (sp) amplitude, action potential (ap) amplitude, and ap threshold, recorded with five types of noninvasive electrodes, were compared with simultaneous bulla recordings. noninvasive electrodes included a needle electrode over the bulla, gold tiptrode (etymotic research, elk grove village, ill), enhancer i (nicolet instrument corp, madison, wis), coats (lifetech inc, austin, tex) ele ...19938318207
hormones and hair growth: variations in androgen receptor content of dermal papilla cells cultured from human and red deer (cervus elaphus) hair follicles.many hair follicles produce different types of hair in response to environmental changes or the mammals age, that are translated to the follicle by hormones. androgens cause many changes, such as transforming vellus follicles producing insignificant hairs on the face to terminal beard ones at puberty or the reverse on the scalp. in male red deer the breeding season rise in androgens causes the annual production of a mane on the neck that is lost during the spring. because the dermal papilla situ ...19938326143
pharyngeal bot flies (oestridae) from sympatric wild cervids in southern spain.the prevalence of 2 species of pharyngeal bot flies parasitizing sympatric wild ungulates from southern spain is given. pharyngomyia picta was found in all red deer and fallow deer whereas cephenemyia auribarbis was found in 59% of fallow deer and 81% of red deer examined. the mean number of p. picta larvae was 3-6 times more than that of c. auribarbis larvae. these data suggest that red deer are more heavily parasitized than fallow deer and that they are predominantly infested with p. picta lar ...19938331487
analysis of the dna-binding and transcriptional activation functions of human fli-1 protein.three of the ets oncogene superfamily members v-ets, spi-1/pu.1 and fli-1, have been shown to be directly involved in retroviral-mediated acute erythroleukemias. the fli-1 gene was found to be rearranged in 75% of the erythroleukemias induced by friend murine leukemia virus (f-mulv), suggesting that it could play a key role in cellular transformation. we have previously isolated and characterized the human fli-1 gene and have found it to be highly homologous (80%) to the human erg-2 gene. human ...19938336942
elk-1 proteins are phosphoproteins and activators of mitogen-activated protein kinase.mitogen-activated protein kinases (map kinases) or meiosis-activated myelin basic protein kinase (p44mpk) are known to be activated by a mechanism involving dual phosphorylation at both tyrosine and serine/threonine in response to many extracellular stimuli. there has been considerable speculation as to whether map kinases are autophosphorylated and activated by an upstream protein kinase (map kinase kinase) or an activator of autophosphorylation or both. here we report that the ets-related prot ...19938339245
genetic analysis of evolutionary relationships among deer (subfamily cervinae).the evolutionary relationships among 10 taxa of deer from the four genera of the subfamily cervinae (cervus, elaphurus, axis, and dama) were examined by a comparison of their electrophoretic types for 22 proteins. we analyzed the data using both phenetic and cladistic methods and found that the genera of the cervinae were not monophyletic. the genus cervus was split into two distinct groups with red deer, wapiti (c. elaphus ssp.), and sika (c. nippon) in one clade and sambar (c. unicolor) and ru ...19938340615

a serologic survey for some bacterial and viral zoonoses in game animals in the czech republic.between 1986 and 1991, sera were collected from 33 roe deer (capreolus capreolus), 24 red deer (cervus elaphus), four fallow deer (dama dama), two mouflon (ovis musimon), 34 wild boars (sus scrofa), and 48 hares (lepus europaeus) shot in two areas of the czech republic. collectively, the sera contained antibodies to coxiella burnetii (prevalence of 12%), francisella tularensis (4%), brucella spp. (2%), central european tick-borne encephalitis virus (8%), tahyna (california serogroup) virus (36%) ...19938258864
activation of ternary complex factor elk-1 by map kinases.ternary complex factors (tcfs), one of which is elk-1, have been implicated in mediation of c-fos induction. they have been shown to be phosphorylated by mitogen-activated protein kinases (mapks) in vitro. we demonstrate that recombinant elk-1 is hyperphosphorylated in vivo upon joint overexpression of mapks and constitutively activated raf-1 kinase, the latter serving as an indirect in vivo activator of mapks. this phosphorylation is accompanied by a conformational change and results in an elev ...19938262053
multimedia environmental monitoring: 50 years at hanford.environmental monitoring has been an ongoing activity on the u.s. department of energy's hanford site in southeastern washington for almost 50 years. objectives are to detect and assess potential impacts of site operations on air, surface and ground waters, foodstuffs, fish, wildlife, soil and vegetation. data from monitoring effects are used to calculate the overall radiological dose to humans working onsite or residing in nearby communities. in 1989, measured hanford site perimeter concentrati ...199324220840
evidence for the promotion of aboveground grassland production by native large herbivores in yellowstone national park.we examined the effect of native large herbivores on aboveground primary production of nonforested habitat in yellowstone national park, wyoming. productivity of vegetation grazed by elk (cervus elaphus) and bison (bison bison) was compared with that of ungrazed (permanently fenced) vegetation at four sites. two methods were used that, we believed, would provide the most accurate measurements under the different grazing regimes encountered in the study. production of ungrazed vegetation in perma ...199328313410
winter ecology of nonmigratory alpine red winter, red deer (cervus elaphus hippelaphus) that are not receiving supplementary feeding emphasize and rely on energy-saving strategies. in severe winters with deep snow, they select a home-range habitat-windblown alpine pastures above the timberline-that meets the requirements of this strategy: a much lower sinking depth and good forage availability are due to patchy snow distribution, while the open area provides higher radiation, permits group formation and thus sociobiological wellbeing ...199328312946
feeding-patch choice by red deer in relation to foraging efficiency : an experiment.we tested the idea that ruminants allocate their feeding time to habitat patches in relation to foraging efficiency. we used five tame red deer (cervus elaphus) in an enclosure planted with four treatment of timothy grass (phleum pratense) differing in their stage of growth. older swards offered higher biomass but lower nutritional quality than younger swards. we observed time spent feeding in each treatment during each of seven trials. we measured goodness-of-fit between observed times and pred ...199328312938

'double-head' antlers in red deer cervus elaphus ssp. in which the antler cores survived the death of the unusual case of spike antlers in male red deer is described in which the antler core apparently survived the partial mineralization of the cortex in the first rut and then in the next year supported a new, "antleroma-like" growth. on one side of the antler beam a "separation gap" developed between the living core and the dead cortex. on the opposite side a new growth of antler tissue was observed; this was made of spongious bone which in some areas partially resembled peruke-like growth and i ...19947819606
cells cultured from the growing tip of red deer antler express alkaline phosphatase and proliferate in response to insulin-like growth factor-i.deer antler growth provides a unique natural model of rapid and complete bone regeneration. in this study, the distal antler tips of male red deer (cervus elaphus) were collected post-mortem during the annual growth period (april-august), and an in vitro system established for the culture of cells from three regions; the inner layer of the perichondrium, the reserve mesenchyme and the cartilage zone. alkaline phosphatase (alp) expression by cultured cells, as demonstrated by enzyme histochemistr ...19947829985
the establishment of a hybrid zone between red and sika deer (genus cervus).japanese sika deer (cervus nippon nippon) were introduced to scotland around 80 years (20 generations) ago. the sika phenotype is expanding its range and hybridizing extensively with native red deer (cervus elaphus) leading to the establishment of a hybrid zone. this zone is currently moving and cannot be considered to be at equilibrium. cervid genotypes and mitochondrial haplotypes were mapped across the sika phenotype range, using diagnostic protein isozymes, microsatellite nuclear dna markers ...19947834107
effects of insulin-like growth factor-i (igf-i) and igf-ii on the growth of antler cells in vitro.the effects of insulin-like growth factors -i and -ii (igf-i and -ii) on the growth of undifferentiated (fibroblast zone) cells from the growing tip of red deer velvet antlers and from cells 1.5 cm distal to the growing tip (cartilage zone) were investigated in primary cell culture. the addition of igf-i or igf-ii to the medium of cultures preincubated in serum-free medium for 24 h increased the rate of [3h]thymidine uptake in a dose-dependent manner in both cell types, with maximal stimulation ...19947836891
immunolocalization of the nuk receptor tyrosine kinase suggests roles in segmental patterning of the brain and axonogenesis.neural kinase (nuk) encodes a murine receptor-like tyrosine kinase belonging to the eph/elk/eck family. protein localization studies indicate that during early embryogenesis nuk is confined to the developing nervous system, where it marks segments along the axis of the neural tube in the hindbrain (rhombomeres r2, r3 and r5) and specific morphological bulges of the midbrain and forebrain. subcellular localization of nuk indicates that this receptor is concentrated at sites of cell-cell contact, ...19948134103
functional dissection of the transcription factor elk-1.the ternary complex factor elk-1 belongs to the ets oncoprotein family. we demonstrate that this transcription factor is localized predominantly in the nucleus, for which at least two regions of elk-1 are required. one of these regions is part of the n-terminal ets-domain, while the other encompasses amino acids 137-157. in conjunction with the ets-domain, which mediates autonomous binding of elk-1 to some dna target sequences, the conserved b-region is both necessary and sufficient for ternary ...19948134131
isolation and characterization of bsk, a growth factor receptor-like tyrosine kinase associated with the limbic system.neuronal degeneration has been shown to be involved in various neurological disorders. growth/trophic factors and their receptors are known to be important for the regeneration and survival of neurons. we report here the molecular cloning of a receptor-like protein tyrosine kinase, bsk, (for brain specific kinase). bsk is highly related to the eph/elk receptor-like kinase family members. northern blot analysis shows that it is expressed specifically in the brain, with no expression detected in a ...19948145300
concurrent sick building syndrome and chronic fatigue syndrome: epidemic neuromyasthenia revisited.sick building syndrome (sbs) is usually characterized by upper respiratory complaints, headache, and mild fatigue. chronic fatigue syndrome (cfs) is an illness with defined criteria including extreme fatigue, sore throat, headache, and neurological symptoms. we investigated three apparent outbreaks of sbs and observed another more serious illness (or illnesses), characterized predominantly by severe fatigue, that was noted by 9 (90%) of the 10 teachers who frequently used a single conference roo ...19948148452
the transcription factors elk-1 and serum response factor interact by direct protein-protein contacts mediated by a short region of elk-1.transcriptional induction of the c-fos gene in response to epidermal growth factor stimulation is mediated in part by a ternary nucleoprotein complex within the promoter consisting of serum response factor (srf), p62tcf/elk-1 and the serum response element (sre). both srf and p62tcf/elk-1 contact the dna and bind in a cooperative manner to the sre. in this study, we demonstrate that srf and elk-1 interact directly in the absence of the sre. a 30-amino-acid peptide from elk-1 (b-box) is both nece ...19948164681
some toxic and trace metals in big game hunted in the northern part of poland in animal meats (muscle, liver and kidneys) collected from different regions in northern part of poland in 1987-1991 were analysed for mercury, cadmium, lead, copper, manganese, zinc and iron. toxic mercury, cadmium and lead occurred in relatively low concentrations in muscle and organ meats, with the exception of lead in muscle and cadmium in kidneys, which were relatively more contaminated. the concentrations of essential trace metals in samples examined seemed to be natural. roe-deer contai ...19948178124
